Importance of Using Fire Dampers in Commercial Areas

Aluminium Technical Engineering Factory Tecnalco -UAE

The word ‘dampers’ refers to products set up in HVAC ductwork to keep flames from propagating in the ductwork. From a safety point of view, it is essential to stop the occurrence of smoke or fire spreads at commercial buildings. As a Aluminium Technical Engineering Factory Tecnalco -UAE, we know how significant it is to use the product commercially as well.

Installed in HVAC system ducts, automatic fire dampers would automatically shut one or more doors in the damper when a rise in temperature is detected. This will keep smoke or fire from spreading through the ducts to the other areas of the commercial building, which uses this passive fire protection device. The importance of using this product is evident from how it works. Nevertheless, in the capacity of being a Aluminium Technical Engineering Factory Tecnalco , we will take a closer look at this topic.

Reasons to Use Fire Dampers at a Commercial Setting

Active fire protection products such as sprinklers can reduce the speed of spreading fire and help with occupant evacuation. However, those forms of fire protection devices alone cannot keep gases or smoke from spreading. For your information, one of the leading causes of unnatural death in commercial fire occurrences is the act of smoke or gas spreading. Operating passive fire dampers do not require the utilization of electricity. Instead, in the case of an increase in temperature, a thermal element or core would melt to allow for spring-operated damper doors or blades to close. You may want to go for horizontal or vertical damper options, according to how these shut the ducting system. Each damper type suits different applications.

It takes only a few seconds for a tiny flame to just grow and be a major occurrence of fire. Cutting off all the possible passageways where flames can travel will allow containing the situation to a single location. This will help to ensure that a building is fireproof. Being fireproof means that you will have one less thing to worry about even on holidays.

On the other hand, the utilization of motorized smoke fire dampers is to prevent the propagation of smoke through the ventilation system of a building. The dampers are typically situated in the ductwork and work by shutting off at the time of smoke detection. As with a fire occurrence, smoke is also likely to propagate fast through a commercial building. In a fire incident, one of the leading reasons for death is smoke inhalation. It is important to keep smoke inhalation from happening to keep your building occupants safe at the time of evacuation. This is where motorized smoke fire dampers have a big role to play.

Sound Attenuator and Commercial Industries: How It Works?

Sound Attenuators Manufacturers in UAE

A sound attenuator is also called a sound trap, duct silencer, or muffler. It is a noise control system of the Heating Ventilating and Air-Conditioning (HVAC) network that is designed for the reduction of noise through the ductwork that gets either from equipment in any building or occupied spaces.

There are different designs and types of HVAC duct silencers and sound attenuators in a system offered by Aluminium technical engineering factory- tecnalco. You may select from a wide range of customized or standard sound attenuator systems for residential or commercial industries that satisfy the needs of the application. The noise caused by HVAC systems becomes too high and the ventilation areas of buildings, enclosures, and equipment rooms become very noisy. The controlling measures include silencers and louvers into the system design that makes the space free from any additive noises. HVAC systems are noisy with the sounds of the electrical and mechanical devices. There are rectangular and circular sound attenuators available for absorbing the sound in the air stream and removing the HVAC noise. The sound produced by HVAC systems is very distractive and the proper installation of sound control systems can ensure the smooth and noise-free working of systems.

Cause of Noise

There are ample reasons for which HVAC systems can become noisy. These systems have an in-built sound absorption technique embedded for keeping the sound low. There are millions of air pockets contained in the Sound Attenuators Manufacturers in UAE. that reduce the noise with the absorption of the passage of acoustic energy. The fans also produce noise with the air vibration and movement of fins. The pressure drop causes the air changes in the system that is a cause of producing the annoying noise. The loose fixing of bolts and nuts even produces a loud noise.

Types of Sound attenuators for HVAC Systems

Cylindrical attenuators: These are fitted in the ducts for 犀利士 silencing the noise from inside. These come with a spinning head with a tail that has the shape of a cone. The circular attenuator has two walls.

Rectangular attenuators: These are fitted over the HVAC system for noise reduction. These include dissipative silencers delivering acoustic energy with sound-absorbing media installed inside them.

In the interior wall of the sound attenuators is the insulation made for reducing the sound to a minimum level. The noise is reduced and the pressure changes in an HVAC system are maintained for making the system flow with ease.

Working of a Sound Attenuator

Sound attenuators are used as an important part of the HVAC system and these are installed to get the best effects for noise cancellation. The Sound attenuators are suggested to be installed by aluminium technical engineering factory-tecnalco, at the time of installation of the HVAC system. The insulation varies in thickness depending on the frequency of the sound produced. Sound attenuation is increased by the enhanced length of the attenuator that controls the HVAC system pressure. Regular maintenance of the system is carried out for reducing the noise and maintaining a check that there are no loose fittings in the maintenance systems.

The silencers are backed by independent testing systems in the laboratory and have applications in the following areas:

  • Commercial, Institutional or Industrial HVAC duct systems

Uncontrolled Fire: Avoid the Risks with Fire Damper

What is a fire damper?

Fire dampers can be found in ducts, air transfer openings, and most places where fire-rated constructions like floors, walls, or other fire obstructions are constructed. If fire dampers are not installed, the fire can easily spread, causing serious damage to property and people present in that environment. The reason behind the concept of compartmentation is to stop the fire from spreading to nearby locations. This method helps a lot in limiting the outburst of fire and therefore reducing damage to property and people. So, in a nutshell, a fire damper is a tool used to stop the outburst of fires. If you’re looking for installation, the best aluminium and technical engineering factory –Tecnalco in UAE can help you in making the appropriate decision and install the Fire Dampers most appropriately to avoid the spread of fire.

Why do we need fire dampers?

One of the most harmful hazards is an outburst of fire that has the potential to be even life-threatening. In uncontrolled situations, fire can roll out through ventilation ductwork and can install systems that are efficient enough to control the fire. It is important to furnish your ventilation ductwork with superior and sturdy fire dampers that can stop smoke from outspreading and hence ensure safety for escape way out.
Fire is not the only hazardous thing in such cases. Gases and smoke released from this fire can pose a real threat to the environment and respiratory health of the people present. There are different chemical reactions taking place in our environment and the smoke and gases can be really dangerous for our ecosystem, destroying its balance in many ways. These gases travel at a high rate and even the smaller amounts can be highly fatal for human beings and animals. Fire dampers can be fitted with special seals that will help in restricting fire along with these gases thus, saving the environment and mankind in many ways.

Operation of fire dampers

Fire dampers can be operated in a very simplified way. They are very convenient and systematic as they close the moment temperature rises above the threshold limit to restrict the fire outburst. The fire dampers aluminium technical engineering factory- Tecnalco in UAE makes installation for the special quality of fire dampers fitted with a fusible link that can be selected according to the desired temperature. After this temperature is crossed, the damper automatically closes.

Fire dampers are very versatile as they can be pneumatic, electrically activated, or manually operated. Electric and pneumatically activated dampers are fitted with fusible tube links that release and block operating voltage to the spring return motor, permitting the spring to close the damper blades. They will open automatically on the change of the fire and the motor is re-established with the operating voltage. In the case of spring-operated dampers, a fusible link will release, permitting the spring to close the damper blades. The fire damper requires to be reset manually when the fuse is changed.

Installation of systems by Fire damper manufacturers in UAE

The installation process should be carried out by trained professionals only. Besides the knowledge about the installation, they should know about the usage of the building’s HVAC and the wiring system. Fire dampers require a proper strategy to be fitted. The location of installation for these devices is very specific to make sure the fire dampers close the moment the outburst starts and prevents it from spreading.

Applications of Volume Control Dampers

HVAC dampers help to monitor air volume by conducting systems and regulate them. In the ductwork with low to medial airflow velocity, control dampers are normally mounted. It can be used to produce positive shutdowns and also to monitor HVAC low-leakage systems automatically.

Dampers are often used in zoning and zone control systems. Air dampers are used to regulate material movement in industries that move gases and liquids through pipes and pipes.

Air Control Dampers come in a variety of sizes and shapes, including square, circle, and rectangular backdrafts, and it is critical to choose the right one for the task. The position, configuration, and function of a damper decide the form of the damper. Zero leakage bubble-tight dampers, volume control dampers, motorized volume dampers, and so on are examples of such dampers.

In this blog, we will discuss volume control dampers.

The Volume Control Damper is a device that regulates airflow through an air duct. Complete manual quadrant or motorized actuators are available with this unit. Volume Control Dampers are ideal for systems requiring air control and can be made of galvanized steel, stainless steel, or aluminium. If you are familiar with the characteristics of volume control dampers, it will be simple to choose from the huge list of dampers offered by VAV manufacturers in the UAE. The size of the volume damper and the area where it will be installed are often the most important factors to consider when selecting one.

The Volume Control Dampers help regulate the volume of airflow to the other sections of the device. These dampers can be fixed within the duct itself and can be manually or automatically. In determining individual HVAC technologies and entire systems, an understanding of the interdependence of HVAC technology between them, as well as other electric loads and maintenance and operational practices is fundamental. As with lighting, HVAC systems have broad and varied technology and potential configurations.

These dampers can be immovable or fixed within the air conditioning system. The volume control dampers’ doors can be opened and closed manually to change them. The ash-pan is also accessible through the volume damper, which allows for the removal of accumulated clinker and the removal of ashes.

From their wide range of products, motorized volume control damper suppliers can fabricate and supply a number of sizes and styles of quantity dampers. Volume Control Dampers made of stainless steel and aluminium sheet are recommended because they have a higher inherent resistance to corrosion and abrasion.
They are ideal for places where there is a lot of moisture and hydration because of the material and construction.

These dampers are simple to adapt to the surrounding temperature and humidity, making them effective at reducing power consumption. The use of the proper volume control damper lowers energy bills. They are effective at lowering the pressure in zone controls, which increases HVAC performance.

Volume control dampers are available for either parallel or opposed blade operation, with each design having its own set of characteristics depending on the type of operation. Parallel blade dampers are designed for all blades moving in the same direction and parallel to one another. When the damper has two positions, open and close, the parallel blade orientation is used. Opposed blade dampers are used on dampers that modulate airflow and are built with blades that pass in opposite directions. When it comes to the location of the dampers within the air conditioning system, they are either fixed or immovable.

The door of the volume control dampers can be opened or closed manually. They even make it possible to empty the ash-pan and dispose of the clinker that has accumulated. The volume control damper’s primary role is to:

  • Control airflow inside a duct.
  • Aid in the maintenance of a set temperature. A volume control damper is important for the heating and cooling of the building in the HVAC system. It controls the temperature.
  • Maintain the necessary pressure.

The dampers consist of several plates, blades, axles, coils, blade fasteners, and other components adapted to the particular application of the damper. The damper’s actuator is used to control the damper’s location using signals from the building automation system, thermostats and controls, pressure switches, and relays. The capacity of the actuator to sufficiently open and close the damper, as well as the amount of torque it can provide, are used to determine which actuator to use. This is usually determined by the following factors:

  • Dimensions of the damper.
  • Air velocity through the damper.
  • The static force acting on the damper.
  • Form of damper blade – parallel or opposed

Always check the seller’s certification label, positive customer reviews, and company credibility before purchasing a damper. Leading volume control damper manufacturers, such as Technalco, are known for producing high-quality products at a reasonable price.

How do you calculate airflow through sand trap louvers?

sand trap louver installation

The fire dampers are key passive fire safety devices and are used in the sector of air conditioning, ventilation, and heating. Generally, a fire damper operates when heat from a fire causes a room’s normal temperature to increase by 165°F, i.e., it is designed to close heat automatically. The fuse connected to the damper melts allowing the door of the damping door to close. In particular, they are situated in a duct at the intersection of the fire barriers in building zones, such as divisions at the point of penetration of the duct, to maintain a wall or floor fire rating. The fire damper guarantees the safety of the current lock.

The fire damper protects the current barrier, preventing fire penetration until temperatures exceed the barrier’s fire-rating level. Its main purpose is to prevent fire from spreading from one side of a fire-rated barrier to the other. The damper is built to withstand high temperatures for as long as possible, and it is manufactured to a high standard of integrity.

When room temperatures reach about 165 degrees Fahrenheit, the fusible component in the fire damper melts, allowing the door to shut. This helps to keep the fire from spreading and causing as much harm as possible. Property owners should be aware that rooms that are regularly heated to 165 degrees or higher would need fire dampers with higher melting point fusible connections.

By preventing the spread of fire by heating, ventilation, and air conditioning ducts, the damper aids in preventing a fire from spreading throughout the home. They also help prevent smoke from spreading through the ductwork in the event of a fire.

In a residential environment, there are two types of fire dampers to choose from. Dynamic and static fire dampers are two types of fire dampers.

Dynamic Fire Dampers

These dampers are built with a spring-loaded design and continuous fan use as vertical barriers. The air pressure generated by the ventilator helps to unlock a loaded door system, enabling the ventilator to stay in operation quickly.

Static Fire Dampers

In contrast to dynamic fire dampers, static fire dampers are installed as horizontal barriers with a curtain-like structure. If a device with static fire dampers is triggered and the door of the damper is decaying due to the weight of the damper, the HVAC fans are set to turn off. Whatever these systems are in use, owners of the property shall contact HVAC technicians to inspect the dampers and remedy any harm at the earliest opportunity.

Fire dampers should be checked and maintained on a regular basis due to their vital safety features. On models with fusible connections, all that is needed for fire damper maintenance is to check that the fusible connection is still present and not covered in grime and dust. Fire dampers with circuits should be tested more frequently. Even if the tests are positive, the dampers should be physically inspected on a regular basis.

Sand Tra犀利士 p Louvers Filter

Sand trap louvres are normally located at the first point of the air intake and are an essential part of any air handling device. Sand trap louvres, as their name implies, prevent sand from accessing the air intake unit or equipment rooms, preventing damage to the equipment’s moving parts. In desert or sandy areas, they are also used for ventilation in parking lots, warehouses, generator rooms, and fan rooms, among other places. In the presence of high dust concentrations, it has a high degree of sand and large dust particle separation. The sand trap louver installation is maintenance-free thanks to the vertically arranged blade parts and holes for sand drainage. It is made to separate big sand and dust particles from the airstream at low speeds, preventing unnecessary dust loading in traditional filters. It is not meant to be used in place of traditional filters. Sand trap louver installation specifically to remove sand and dust from the air. It is efficient and appropriate to use for air handling unit ventilation and inlet ducts. Since it comes with a complete aluminium extruded profile unit, the assembly is corrosion-resistant and suitable for different weather conditions. For sand trap louver installation, filters and dampers are available as options.

We need the means to include the free area and First Water Penetration in a meaningful way to better assess a louvre’s capacity. Since the ultimate goal is to get maximum air via the louvre, we want to determine the permissible air volume through the louvre (cubic feet per minute or cfm). The AMCA Standard 500-L Laboratory Methods for Air Louvers Testing for these concepts are protected by the test methods.

The following example compares two louvres with different performance characteristics for a 48″ wide x 48″ high wall opening:

Louver Free Area (percentage)Free Area for 48″ x 48″ (square feet)First Point Water (fpm)

We could conclude that Louver 2 is better than Louver 1 for getting more air through the louvre because it has a larger free region.

LouverFree Area (percentage)Free Area for 48″ x 48″ (square feet)First Point Water (fpm)Design Velocity (fpm)Volume of Air (cfm)

For a 48″ wide x 48″ high wall opening, Louver 1 has a 45 percent-free space. The gross free area is 7.2 square feet (45 % x 16 square feet of wall opening). For this louvre, the tested First Point of Water Penetration is 1190 feet per minute-free area velocity. We should account for any difference in the airflow through the louvre by using a safety factor – we have selected a 25% safety factor. With the safety factor, the geometry velocity will be 25% less than 1190 fpm, or 893 fpm (1190 x .75). By multiplying the louvre-free area by the design velocity, we can now calculate how much air can be safely passed through the louvre ( 7.2 sq ft x 893 fpm). Louver 1 has a volume of air of 6424 cfm as a result.

When we do the same calculations for Louver 2, the result is just 4781 cfm (with a 25% protection factor). The amount of air passed into the same opening size is 25% lower. Louvre 1’s a safer option because we can deal with the pressure drop at higher airflow rates!

The majority of manufacturers list the airflow resistance of their louvres on their websites. Based on the blade and frame shapes and angles, each louvre will have a slightly different resistance.

Most louvres do not deviate significantly from the graphs, unless they are built for extremely high air velocities, such as wind-driven rain louvres. We can measure the resistance for each louvre at the design velocities and see that:

Louver 1 – at 893 fpm-free area velocity, will create 0.090 inches w.g. of static pressure

Louver 2 – at 563 fpm free area velocity, will create 0.055 inches w.g. of static pressure

The two values must be suitable to the design of HVAC systems, and our Louvre 1 is the best option, even if the area is less free of charge. For most applications, a reasonable thumb rule is to remain below 0.2 inches w.g. static pressure.

How do fire dampers work as ventilators?

Fire damper manufacturer in UAE

The property owners recognize the importance of adequate steps or measures against fire damage. Fire damper manufacturer in UAE can install the equipment in different areas at home or in a commercial building. Although the damper is not the only product to look for, it is important to inspect the different other parts of the system to work efficiently in the misfortunate event of a fire. The latest HVAC air distribution products in UAE include the fire dampers as the pre-installed system. It is important to get the periodic inspection and repaired and understand their working.

How do they work?

Fire dampers begin the operation when the room temperatures go up to 165°F. This is the point at which the fuse of the fire damper will melt and the door closes automatically. The property owners need to understand that the places at which the fire dampers are installed usually do not get this temperature and have higher melting points than 165°F.

What is the necessity?

It is important to incorporate the fire safety equipment in the ductwork of any house or office. The exhaust valves exporters in UAE give different options to choose from and install the equipment to spread fire during an accident. The fire spread is retarded to spread to the rest of the home and the smoke doesn’t travel through the ductwork in any fire event.

Fire Dampers in Ventilation Systems

The fire damper manufacturer in UAE intends to install the systems in ventilation areas as the cut-off baffles that separate the fire zone from the rest of the building. The major function of KWP type of fire dampers is to restrain the fire spread, temperature, and smoke. It additionally uses the actuators for use in the mixed ventilation systems. There are fire dampers available for vertical and horizontal installation that is used in walls and ceiling-fixed AC systems.

A fire damper is constructed, manufactured, and tested as per the standards for Ventilation for Buildings. The sensitivity of the equipment is checked by the tests following the guidelines for the testing and service installation. The usual construction of a fire damper consists of two bodies manufactured using the galvanized steel that is separated by the insulated dividers with a thick fire-resistant material. Fire dampers are manufactured for use in chemically aggressive surroundings, such as laboratories, the food industry, the chemical industry, or similar platforms. In this case, the steel components are replaced by acid-resistant steel that doesn’t corrode or wears away soon.

Using Intake and Exhaust Air Louvre for Fresh Air

Intake and Exhaust Air Louvre

There’s a growing need to provide buildings with fresh outdoor air in the present era of sustainable buildings. This ensures that there will continue to be the need to cover outdoor air and construction exhaust openings with louvers. Construction envelopes and components that secure them have evolved and will continue their adaptation to meet evolving requirements in design and code.

Air distribution systems include air handlers, conductors, and related heating, ventilation, and air conditioning elements. It provides fresh air, preserving ample indoor quality while providing air conditioning for offsetting heating or cooling. Multiple elements must function in tandem to ensure the optimal conditions are preserved. They use relatively big quantities of energy to dramatically minimize energy usage by smart operating techniques and good maintenance practices.

Types of Louvre

A Louvre is a multi-blades system that allows air to flow but prevents the entry of water or other elements when placed within an opening.

Intake and Exhaust Air Louvre

For centuries Traditional louvers non-drainable blades with “Z” or “J” have been in use in the building. They provide a means to broad airflow volumes but provide almost no rain security. This lack led to non-drainable blade louvers type “K.”

The design of the blade was originally known as a “storm-proof” and had a rain hook. Unfortunately, they are not up to their name, which offers very little rain cover.

To mitigate the consequences of water infiltration, drainable blade louvers were made. With hopes of better performance over a single drainable louvers blade, the dual- drainable blade louver was created. These louvers, however, gave limited rain protection and in wind-driven rain conditions were unsuccessful.

AMCA added a new test to its ANSI/AMCA standard 500-L1 in response to a request for higher standards of envelope safety. The initial water penetration test uses still air and is still a criterion assessment. The revised test standard however addressed severe weather-related problems in the louver sector, which were loosely based on European HEVAC test standards.

This shift in market demand contributes to the development of a new product, the rain louver powered by wind.

Typical rain louvers powered by wind can be characterized, at times, by their narrow blade centers, sophisticated aerodynamic blade shapes, and front and rear rain gutters. The louvers reduce the effective water penetration inside buildings and have considerably higher airflow capability than traditional ranges in many instances.

In a certain application, the three most common performance requirements assessed for intake and exhaust air louver selection are the following:

    Pressure drop is the pressure difference in a flux system between two stages. It is also called air efficiency.
    Free area is the minimum area that air can enter, typically as a percentage. The face field, which is a whole section of a louver, should not be disturbed.
    The resistance to water penetration calculates the quantity of water that passes through a louver under certain airflow conditions. It is the weight of the water that moves through the open air at a defined free area speed. The maximum rate of speed is 6.35 m/s 1250 fpm for water penetration.

When defining three things – louver selection parameters, application design, and local building code design parameters – it is ensured that they are best qualified to choose the right louver model for the application. The majority of conventional louvers are tested on the basis of the above criteria for performance: pressure drop, free area, and resistance to water penetration.

In particular, Rain infiltration can cause huge problems inside a building, from rotting ceiling tiles, drywall, mold growth to personal injury damage to equipment due to wet floors. It should be noted that the ANSI / AMCA Water penetration test standard 500-L is still an air test, which replicates silent precipitation without wind impact. During this test, two methods of water are added to the louver.

Simulated rainfall from above the louver falls under the first process. The second one, which simulates rain flowing down the face of a wall, is spraying water in a test chamber bulkhead above the louver. Airflow from behind is traveled through the louver and there is no wind impact during the examination. The objective of the test is to evaluate the speed of the free area by louver occurs when water penetration is 3 mL (0.01 oz) (mass) per square foot of free space. The maximum AMCA rating for water-penetration measured for airflow is 6.35 meters/s (1250 fpm) for free areas.

Although conventional louvers can escape some rainfall in calm rainy weather, they are much less successful in wind-driven rainy weather conditions.

A specifier should bear in mind that a percentage free area when choosing a louver is not an overall output measure. It is simply an indication that the unique louver model can handle larger air quantities. The architecture of the blade directly affects the pressure drop. The more measures, the more rain hooks and the drainage provisions are usually available in a blade configuration, the greater the effect on-air performance.

The spacing of the blades and layout, airflow path, drainage panels, and rear structural supports can also affect the efficiency of the water penetration.

Checking real-world conditions are crucial for all of the layout versatility of a louver. Louvers should not only look fine but also work in different elements of nature. The construction and component design of different geographical regions need numerous considerations.

The ANSI/AMCA Standard was tested for wind-driven rain-resistant louvers. 500 L rain test parameters powered by the wind, which simulate conditions of the storm. The trial compares the amount of water the louver rejects to how much water an identically wide opening can penetrate without a louver to stop the rain.

The airflow is drawn into the opening during this test, while the wind is simultaneously face blown. Water would then be carried into the airway and then pushed by the wind on the louver. The storm conditions can be used in the test at two different stages. The fundamental requirement applies winds of 13 m/s (29 mph), and rain of 75 mm/hr (3 in.) (8 in./hr) of rain. Airflow is drawn into the louver at different rates and Penetration of water is determined by grams or ounces (volume) based on a one-hour duration.

A test was conducted in a comparison test to the basic situation, of 13 m/s (29 mph) winds and 75 mph (3 pounds per hour) of rain, of the conventional drainable blade louver, which has obtained the highest level possible in the ANSI/AMCA Standard 500-L water penetration test. Many wind-driven rain louvers may deliver 99% or better rain refusal at the maximum airflow system available. The traditional louver instead rejected only about 65% of the water applied and allowed about 25 times the water for comparison tests.

Before specifying, designers should consider how a louver works, and several test methods and certifications are designed for making the decision. Louvre producers may use various test methods and laboratory setups to arrive at their independent performance results. The use of a third-party certification body is advisable to ensure that the cataloged performance data is reliable and up-to-date.

AMCA is a third-party inspection body that also produces American peer-vetted national test louvers standards. ANSI/AMCA Standard 500-L is the most common AMCA standard used to assess and monitor for the efficiency of louvers. AMCA Certified Ratings Program (CRP) for air control items is also conducted by the association. AMCA Publication 511 includes recommendations for certifying performance scores.

If the CRP has approved the production of the exhaust valves exporters UAE, the specifier should ensure that its performance test data are obtained in the nationally certified form in accordance with the methods indicated. AMCA personnel also control the process.

Catalog of the product line, ensuring accurate ratings and information. In order to preserve the integrity of the information, a product line then undergoes a check inspection at prescribed intervals.

The product can’t be sealed by AMCA itself. However, catalogs, datasheets, and electronic software should be included in the suppliers. Lovers may be approved for

  • Efficiency of the air
  • Audio output
  • Water penetration
  • Wind-driven rain
  • Wind-driven sand
  • Air leakage

Manufacturers of intake and exhaust air louver can choose to have 1 seal for each form of license or combined seal.

In order to achieve the performance characteristics required for a given application, architects and engineers should properly specify louvers. In addition to the general details of the structure, it is recommended that the percentage of the free space, the maximum permissible pressure drop, the starting point for a wind-driven rain penetration (usually class A) be specified at the specified free-area ventilation rate.
This language should accompany the requirements in order to ensure louvers are AMCA accredited and follow the standards chosen by the specifier.

Building owners and designers will still face obstacles. With the increasing requirement for fresh outdoor air and focus on overall device effectiveness, the technology and testing requirements for louver construction have been continually improved to meet the changing demands of the construction industry. Understanding the design criteria and the types of louvers available for the project location will help you select the intake and exhaust air louver that best defends against the elements, ensuring accurate ventilation and maximum system performance. And AMCA-certified louvers help to ensure that your design works as planned.

Types of HVAC system

Here let’s check out the type of HVAC system available for commercial buildings-

1. Centralized

As the name indicates, a centralized HVAC system is a single unit fulfilling the entire building’s needs. Typically, the centralized system is located in a single area. The system is a consolidated unit and uses water as a cooling medium and extensive ductwork for its distribution. A centralized system is not only easy to control but also offers more significant load management potential.

Though the set up can be a bit expensive, it is absolutely worth it.

2. Packed

For buildings with smaller spaces, a packed HVAC system is used. Both packed air conditioning and heating systems are available in one packet unit, which contains the following-
• The air conditioner/fan coil in one unit/heat pump together with the evaporator

• Control/ Thermostat interface offering complete control of the system.

• Optimal air quality improver can include air purifiers, UV lamps, ventilators, or anything that helps make the air in your home or office clean before circulation.

Finding a packed HVAC system is relatively easy with the air distribution product manufacturers in UAE. Not only can you get quality products with the right one but affordable products.

3. Individual-

Decentralized for individual HVAC systems provide energy or meet the need for a building using various individual units located in different building locations. For instance, self-contained unit packages are rooftop HVAC systems, while for the rooms, there are air conditioning units and air to air heaters.

One of the most significant advantages of individual HVAC systems is that they are easy to control and require lower investments. However, they are not recommended for large buildings as they require great maintenance if the system is distributed across the building. Moreover, it is essential to consolidate systems to break all leaks and are expensive to replace.

So, while choosing an HVAC for your requirement, make sure to consider various factors like your building area, your requirement, budget, efficiency, and various other aspects to find the right one for you.

How does an HVAC system work?

Just like any other climate control device, the HVAC system is made up of three main components-


When it comes to the heating part of an HVAC system, a furnace, heat pump, or boiler fulfills the aspect. While a furnace works by burning fuel to circulate and provide warmth throughout the room, a heat pump operates just like an air conditioner in reverse.

In the same way, cool air is provided via two methods- air conditioners and heat pumps in cooling mode, both of the methods efficiently removing the heat in the room. The cooling system uses refrigerants to provide cool air inside the building while eliminating excess humidity to ventilate the space.


The HVAC system’s ventilation system removes the stale air and any foul smell from inside the building while replacing all of it with fresh outdoor air. The system works by removing some of the heat, carbon dioxide, dust, and moisture from the space and fills it with fresh air.

Not just this, but the system also works as an efficient humidifier as it can very well remove excess humidity from inside the room to improve the air quality.

Temperature control

Typically, all of the HVAC systems are controllable with a thermostat program, designed specifically to suit the required temperature of those in the room. An 犀利士
