Your structure is built to support a range of enhancements that improve its functionality. Some of these, like the gutters and downspouts, aid in water drainage to stop moisture buildup in a building’s structure and foundation.

The air quality and comfort for everyone inside the building are improved by other elements like vents and windows and intake and exhaust air louvre, which assist the flow of air throughout the building.

What are Architectural Louvers?

they let airflow while preventing rain and other debris from entering the building. Certain architectural concepts enable a building’s façade to supply natural ventilation so that the structure can “breathe.”

Most buildings have louvre systems from the air distribution products manufacturer UAE installed to ensure a smoother air intake and exhaust as well as stronger protection against rain and noise intrusion. Yet, engineers and architects can employ louvres in a variety of ways. They can also be utilised as an inexpensive yet attractive architectural feature for building facades, or as a simple yet effective screening solution for structures to conceal unattractive equipment.

Intake and exhaust air louvres can be used for a variety of performance kinds, such as drainable, non-drainable, resistant to wind-driven rain, combination, thin-line, rated for acoustics, adjustable, and even resistant to extreme weather.

Benefits of Louvers:

• Energy-Efficiency

Louvre windows contribute to energy efficiency in the home and are more than just decorative window accents. In bathrooms and laundry rooms, louvre windows are a fantastic replacement for exhaust fans because they let humid air escape and prevent moisture buildup.

Louvre windows can also be used for cooling and ventilation in a variety of rooms throughout the house, reducing the need for fans and air conditioning. As a result, your power cost will increase much more gradually.

• Airflow

Louvre windows are most frequently utilised because of how well they ventilate. Louvre windows enable steady air flow into the home through effective ventilation, more so than normal windows, keeping the interior cool, comfortable, and healthy even when it is raining outside. They are not impacted by the direction of the wind, unlike casement or awning windows.

For ventilation in spaces with higher ceilings, louvre windows can be fitted at any height. These louvres can still be simply manipulated using a convenient map-rod.

• Privacy and Security

Louvre windows offer a high degree of privacy while providing excellent ventilation. For increased seclusion, Louvres are available in a range of frosted and coloured glass options.

Moreover, they can be slanted at angles that guarantee occupant privacy without obstructing the entry of fresh air. For of this, they are especially well suited for private areas of the house like bathrooms and bedrooms.

• Natural Light

Louvre windows are excellent for regulating the amount of light that enters a space. They let home occupants to experience natural sunshine without the negative effects of direct, intense sunlight, unlike ordinary windows, when made of clear glass or left totally open.

In contrast, energy-efficient windows with frosted or coloured glass louvres can be used to reduce and regulate the amount of light and heat that enters your home.

• Easy Cleaning

Conventional windows are difficult to maintain and get dirty easily. Louvre windows also have the advantage of being much simpler to maintain than many other window styles.

The louvre blades can be cleaned from the inside by simply tilting the slats open 180 degrees. This is especially helpful for windows on higher floors that could be challenging to reach from the outside.

Final Thoughts

Moving flaps were introduced into louvres to control flooding and lessen hydrostatic pressure on walls of heavy infrastructure like dams, aerodromes, and aeroplanes.

They are incredibly effective in industrial design for bringing in outside air, purifying the air inside, and expelling stale air. They work in conjunction with mechanical components to offer an efficient, cost-effective industrial ventilation system. By allowing air in throughout the summer, they also assist in controlling the temperature within the industry. Contact Technalco, the best air filter supplier in UAE.

Are you looking for the best air distribution products manufacturer UAE? The engineer will next choose the precise sizes, types, and configurations of the terminal units that will provide the area with comfort after calculating the building’s cooling/heating load and laying out the VAV system.

There are a number of factors to take into account when choosing single duct or fan powered terminal units, including unit capacities, sound, type, heating requirements & kind, and manufacturer.

What is VAV?

A heating, ventilation, and air conditioning (HVAC) system that provides air at variable quantities or amounts while maintaining a constant temperature is known as a VAV.

VAV HVACs are chosen over continuous airflow systems, which deliver air at varying temperatures, because they offer better temperature control, a longer parts lifespan, less noise, and more energy efficiency.

VAV systems with multiple zones are a development of VAVs. These are made up of numerous VAV terminal units or boxes that distribute air in particular regions of a big indoor environment, like an auditorium.

VAV Equipment Selection:

• Refer to Noise Criteria Value

Select a VAV box using the following NC values:

• General offices: NC 30 to NC 35.
• Open-plan-office areas: NC 40.
• Conference rooms: NC 30.
• Auditoriums: NC 30.
• Lobbies and corridors: NC 40.
• Executive offices: NC 25 to NC 30.
• Computer/equipment rooms: NC 40 to NC 45.
• Classrooms: NC 25 to NC 30.

When a VAV box has a hard duct at its intake, a lined exit plenum, and a flexible duct between its plenum and diffusers, discharge noise is rarely a problem. The maximum rating of a VAV box placed atop a typical acoustical ceiling should typically be no more than 5 NC higher than the ideal room rating to account for radiated noise. For instance, a general office with a desired NC level of 30 should not have a maximum VAV box rating of NC 35.

• Ensure Maximum Airflow matches Required Minimum Airflow Capacity

Heating airflow often has the lowest airflow. The design minimum airflow may be considerably less than the airflow offered by a vendor’s product since velocity can be challenging to measure precisely with varied airflow rates. As long as the vendor’s controls allow for 0 cfm as the lowest airflow option, this is allowed.

This essentially means that a VAV box will cycle on and off as needed to maintain the room’s temperature. Although it might not be ideal, this is frequently the only choice.

• Calculate Total Pressure Drop

Selection should be aided by total pressure decrease, not only vendor-listed static-pressure drop. Total pressure drop should not exceed 0.5 in. wc, with the exception of critical noise applications (NC 25 or below), for which static-pressure values should be input progressively lower into a selection programme until a desirable alternative is found. Following is a formula for calculating total pressure drop:

Delta TP = delta SP + delta VP

where:

TP = total pressure drop
SP = static pressure
VP = velocity pressure
Delta TP = delta SP + [(Vin ÷ 4,005)2 – (Vout ÷ 4,005)2]

The decision about a VAV box is independent of the controls supplier. It is possible to factory-install third-party controllers on a VAV box. While it might not save money, it does shorten the time needed for procurement by delaying field installation. Coordination before building is necessary.

Louvers appear straightforward—they are only blades in a frame—but there are several crucial aspects to take into account when selecting one for a particular application. Are you looking for the best HVAC air distribution products in UAE? Tecnalco Aluminium Technical Engineering Factory is your right option for it.

In this blog, we go through few fundamental things to think about while selecting the appropriate louvre for the job.

What are Louvers?

Since the Middle Ages, louvres have been employed in construction openings to let air into a structure while keeping out unwelcome elements like water, birds, and garbage. Louvers are now used by architects not just to create eye-catching and distinctive exteriors but also as the first line of defence against water damage to HVAC systems and ducting.

Maximizing the advantages of louvre design and function requires a basic understanding of performance parameters early in the selection process. This method of choosing louvres promotes optimal HVAC system performance and lessens the need for more expensive repairs due to damage to air handling equipment. Select the louvers from the best intake and exhaust air louvre manufacturers in UAE.

• Protection

The louvre should be made to stop rain and debris from entering your HVAC system. Here, a number of things are involved. A louvre should offer protection, but how much protection is required depends depend on how it will be used. The ability of common louvres to reject water from mild rainfall can be evaluated for water penetration. Testing for wind-driven rain will be necessary for severe weather louvres.

• Performance

The louvre should pose as little impediment as possible to airflow through its open area. All louvres will offer some resistance; however hurricane and severe weather louvres will offer greater resistance than regular louvres. Pressure drop, or the loss of pressure when air travels through the louvre, is the term used to describe this resistance.

The air performance of the louvre is specifically impacted by factors including free area, face velocity, and system effects like ductwork. This short article from our Condenser series, Air Performance and Keeping the Flow, will help you brush up on air performance.

• Aesthetic

Louvers should complement the design of the building. Regardless of where they are installed, they should look beautiful. Both personal preference and the overall aesthetic of the project will play a role in this choice. To ensure that each louvre fits your expectations, manufacturers offer basic colours and color-matching alternatives. Any louver’s finish adds colour, but over time, it may start to lose its lustre.

Any finish can become damaged by sunlight, and the louver’s colour can deteriorate. You must select a finish that can withstand salt spray if your louvre will be installed in a coastal area. How long it maintains its original colour will depend on the type of finish you use.

• Airflow Direction

The direction of airflow should be your next priority. You must determine whether the louvre will cover an intake point or an exhaust point on your building if it will be utilised for ventilation.

Louvers designed for various types of flow will have features that set them apart from exhaust louvres. You must take into account how the louvre rejects water and other undesirable materials since they draw air into the system.

• Blade Styles

The louvre is made up of blades, and different applications will require different types of blades. Louvers can have either stationary or adjustable blades, or a combination of both.

The possibilities of the louvre are determined by the blade profiles; choose straight profiles for air performance, baffle profiles to prevent water infiltration, or chevron profiles for the greatest wind driven rain protection.

• Air Volume and Face Velocity

The amount of air flowing through the louvre is referred to as air volume and is measured in CFM (cubic feet per minute). The air flow across the face of the louvre is measured in terms of face velocity. FPM(feet per minute) is often used to express face velocity.

The air performance of the louvre, which determines how the louvre manages air flow, may be determined using these two variables. All louvres depend on air volume and face velocity.

Conclusion

Although each application may require further consideration, these ten qualities are crucial. The application may also be influenced by external circumstances, such as the wind speed in the vicinity of the louvre. Before selecting the louvre, compile a comprehensive list of criteria and considerations.

There are many volume control damper manufacturers in UAE. The challenge is to choose from different types of damper systems. That said, this article is for you and can really help you make the right choice.

Buildings with numerous rooms, like offices or schools, may have huge and intricate HVAC systems. To supply air to each of these regions, more than just ductwork will be required. Dampers are used in this situation. Devices with blades enclosed in a square or rectangular framework are called dampers. The style and type of the damper can affect how this design is constructed. For example, some dampers may have a rounded frame to fit into ducting that is rounded. You will also find Fire damper manufacturers in the UAE who are there to provide you with high-quality dampers at a budget-friendly price.

There are several distinct types of dampers, each of which has a particular function despite having a similar design. The five types of dampers that are frequently encountered in HVAC systems are listed below.

1. Control dampers

The airflow through the system is regulated by control dampers that are positioned at various locations in the ductwork. These dampers can also be modified for usage in air mixing zones to heat and cool the air. Many times, throughout the day, control dampers will completely open or completely close their blades to fulfil their task.

2. Balancing dampers

Rooms connected to the ductwork have balanced dampers installed to control air pressure. Uneven air pressure can result in minor inconveniences for residents like slamming doors or sporadic air rushes, but it can also result in more serious issues for the overall system. An unbalanced space may be harder to heat or cool, which puts an excessive amount of stress on the air handling devices.

Technicians balance dampers by changing the angle at which the blades of the damper are angled while measuring the air pressure in the space. The blades of the balancing damper are locked in place to preserve the required air pressure once the proper air pressure has been identified. You can unlock them for future alterations.

3. Backdraft Dampers

To limit airflow to one direction only, backdraft dampers are fitted in particular locations within the duct system. Each blade of these dampers has a shaft attached to one end of it. The blade is transformed into a flap in this design, and it only opens when the air is moving in the desired direction.

The blades of a backdraft damper will close if no air is travelling through them or if air starts to move in the opposite direction. Installing a counterweight in a backdraft damper might help or hinder the opening action. These dampers are not equipped with actuators.

4. Multi-Zone Dampers

Multi-zone dampers are utilized in structures with a single air handling unit, such as modest office buildings or single-building schools. These are substantial assemblies of dampers, each of which is connected to a different zone. Multi-zone dampers are duct-connected devices that regulate the airflow throughout the entire system. A multi-zone damper will have several actuators, each of which will control a different zone. These dampers are frequently sold as a whole package with the air handling unit.

5. Industrial Dampers

Industrial dampers are made to stand up to extreme air pressures and constant temperatures of over 250°F. To survive harsh environments, they are constructed from thick gauge materials, mainly steel. For ultimate durability, each component is securely welded into place.

These dampers are frequently used in power plants and manufacturing plants, sites with significant airflow requirements. The industrial ones are the heaviest available dampers.

Conclusion

There are various types of dampers available, and each type has a specific function. With the exception of the single multi-zone damper, which is installed with a single air handling unit, your HVAC system may need that all of these dampers work together. It’s crucial to understand what each damper works and how it fits into your HVAC system even though you will probably use all of these dampers.

In HVAC system sand trap louver are used to take the fresh air in as they are designed to separate particles of sand and dust at low air velocity. The secondary filter will not be loaded with dust and sand particles and hence are the pre filters of sand particles.

Construction of sand trap louver

Blades and frames

These are the main parts of sand trap louver and the equipment have blades and frames of 12mm and 1.5mm thickness respectively.

Bird screen

12mm X 1mm diameter is the standard size of GI wire mesh and the aluminium wire mesh is of different measurement that is 12mm X 12mm X 1.5mm.

Drainage hole

The bottom of the pre filter has holes with a diameter of 20mm for drainage purposes.

Filter frame

20 gauge aluminium sheets are used to make a filter frame.

Filter media

Expanded aluminium is majorly used and optional synthetic filter can also be used.

Specifications of sand trap louver:

High quality extruded aluminium is used to construct the blades and frames giving the advantage of rigidity. It also helps the sand trap louver to be corrosive resistant or corrosion free. A set of composed inverted U-channel are vertically mounted with two opposite rows. And then the bottom of the pre filter has 20mm diameter holes in two rows for the purpose of filtering and drainage of sand particles. To serve the purpose of filter media, the sand trap louver has washable extruded aluminium with aluminium mesh. The thickness of the filter varies as 12mm, 25mm and 50mm.

It is specifically designed to work at higher and medium air velocities. As it can hold sand and dust particles without blocking the air flow, hence ensuring good quality air flow in the premises. For the ventilation of air and inlet duct of air condition system, sand trap installation has become popular. They are appreciated for high quality function as it can operate at high dust concentration and separate sand particles from the air stream ensuring unhindered air flow.

Sand trap louver is specifically installed to purify the air from any dust and dirt particles. It ensures our access to clean and pure air inside the building with no harm to HVAC and other sensitive equipments like electronics. The self emptying mechanisms top the purpose of sand trap louver.
