It is possible to attain the required temperature in forced air systems without wasting the precious energy. If you have invested smartly in the ducting material, then you can combine heating and cooling benefits from the same ductwork.

Forced air systems rely on ductwork for their performance, so you have to invest in the best designs and material to ensure the airflow is distributed evenly in every room.

The Options

When you make purchase decisions regarding the ductwork for your HVAC system, your options can be either aluminum or stainless steel. Pick stainless steel ducting for industrial exhaust applications or highly corrosive areas; whereas, flexible ductwork developed from aluminum, can be your ideal choice for extreme temperature applications.

There are lots of ducting suppliers offering industry compliant ducts. For instance, you can procure quality tested ducts made from stainless steel and aluminum from KAD Air Conditioning, which is the largest supplier in Dubai offering the competitively priced models for AC ducts.

The Best Ducting Material for Your HVAC System

Air ducts are used in heating, ventilation and air conditioning systems for the delivery and removal of air. They are available in a wide range of shapes and sizes and are manufactured from a variety of materials. Sheet metal ducts and fiberglass duct boards are the most popularly used ducts, and they can be availed easily from ducting suppliers in today’s market.

In many regions, leveraging on cavities in the building has become a great option. These cavities can be easily used for the home ducting system as they allow very little or no leakage and allow even air flow. Sheet metal ducts are popular due to their ease of installation and sturdiness. Their longevity and corrosion resisting ability make them the best choice for ductwork.

They are commonly constructed from Galvanized steel and are available in round and rectangular shapes. The disadvantage of sheet metal ducts is that there a high chance of leakage at the welded joints. Fiberglass duct boards provide thermal insulation. They form a network of large shaft lines that are connected to smaller air ducts. They have the capability to absorb sound, and so they provide noise-free functioning of HVAC systems.

Flexible duct manufacturers fabricate ducts from flexible plastics that are coiled over a metal wire to shape it into a tube. Also termed popularly as flex, these ducts are manufactured with a large diameter. Flexible ducts are used due to their flexibility and are ideal for long lengths.

They need lesser number of joints and can be coiled around obstructions and cramped spaces. But installing these ducts requires great care and attention as they can be easily cut or crushed. Also, careful work is required in placed where flexible ducts are joined with a metal sheet to prevent risks of leakage.

The best material for ducting depends on the type of your system and the building in which it will be installed. Ducting suppliers are capable of offering a wide range of ducts as per your requirements. Make sure you choose the best for your project.

Different Types of Grilles and Diffusers such as Perforated Ceiling Diffusers

There exists a subtle difference between grilles and diffusers such as perforated ceiling diffusers. Grilles are devices that have been manufactured so that they can supply air in a vertical position without suffering from any deflected air - which would lose its flow, power and velocity. Perforated ceiling diffusers, or swirl diffuser - virtually any type of diffuser has little vents all around it. These are also called blades and these blades have the function of distributing or diffusing the air throughout the indoor space. The air that comes through from ventilation diffusers is cut at an angle in order to let this happen. 

There are many different types of ventilation grilles and diffusers. Many of these are differentiated between in terms of materials used, function, and applicability to different situations. Some of the different types of materials that grilles and diffusers are made of are:
1. Aluminium
2. Steel
3. Stainless steel
4. Plastic

These can all be given various finishes, in any colour of choice if required. Other finishes can be of stainless steel or brushed aluminium, among a few others. Variable air volume system manufacturers also sometimes coat their products in similar finishes.

There are many types of grilles and diffusers in general that a client can choose from. The most commonly chosen among these include:

1. Egg Crate Grille : These are very simple grilles that are also very affordable. They are usually used when air needs to be extracted.
2. Bar Grille : Bars are included instead of blades in this type of grille.
3. Transfer Grille : Mostly used to provide ventilation but are also useful for preventing the spread of smoke and fire in such an event.
4. Louvre Bladed Diffuser : Very commonly seen in this region, these ceiling diffusers are capable of directing air in up to 4 directions.
5. Straight Bladed Diffuser : Similar to the previous diffusers, but are quite cheaper in comparison. They also sport adjustable blades.

The Importance of Fire Rated Access Doors & Other Maintenance Tips for Fire Dampers

Fire dampers are an inescapably important part of a residential or commercial building’s HVAC system. Fire dampers have a fusible link attached to them that melt when the temperature inside the duct goes above the acceptable limit, which closes the fire damper down, thus preventing the uncontrolled spread of the flame.

Fire dampers need to be tested and maintained thoroughly. The initial test of the fire damper is done at the time of its installation, after which it is again performed the following year. According to regional laws and regulations, the fire damper can be tested every 4 - 6 years after the second test. In order to properly test, maintain, and repair these dampers, the presence of fire rated access doors is of paramount importance. These must be fitted in the duct system by air conditioning companies in UAE at the time of installing the ducts in the building.

Fire dampers are essential enough to the safety of the building’s inhabitants and property that any detection of improper functioning must immediately be met with repairs and/or replacements of faulty parts, like springs or crookedly attached panels.

The dampers and fire rated access doors must also be maintained regularly, checking for any signs of physical damage and alien objects and particles that could obstruct its proper functioning. Missing small parts and proper labelling is also a priority.

During testing, ensure that the fire damper is able to close completely to its intended extent.

If the fusible link is found to be damaged it should immediately be replaced by the same type of link. The parameters of the new fusible link, such as size, temperate range, and load limit should be double checked to ensure that they are the same as the link that is being replaced.

These measures are very important because a fire can occur at any time, and if one does occur while a fire damper is waiting to be repaired or is overdue on a maintenance check, not only will the fire spread uninhibited and damage a lot of property and take potential lives, but it will also leave the building owner’s highly accountable for negligent behavior.

How Variable Air Volume System Manufacturers can Help You Reduce Energy Consumption

During a time of global climate crisis, all home and business owners are concerned with the rising price of energy, both economic and environmental. The vast majority of home and business owners who have an HVAC system installed in their place of work and living try to find ways to curb the amount of energy that is consumed by the heating and cooling equipment. This energy utilization is hugely heightened by the presence of severe temperatures during the summer and winter seasons. However, it is possible to control this energy use, and that is through regulating the flow of air inside an HVAC system, which is where variable air volume system manufacturers comes in. 

VAV systems offer owners of HVAC systems several advantages. The simplest kind of system manufactured by variable air volume system manufacturers supplies evenly heated and cooled air, the air flow of which is variable according to the requirements of the thermostat controlling the temperature of the zone the VAV system is serving. This kind of precise temperature control is one of its greatest advantages that allows for highly effective heating and cooling while conserving energy at remarkable rates. Another important distinction to make in the case of VAV air flow is the resulting dehumidification. Since the air flow is often reduced in many circumstances, the air is exposed for much longer periods of time than is normal to the cooling coils inside the HVAC system. Water vapour from this air condenses onto the coils and as a result dehumidifies the air, which creates a larger sense of comfort to the inhabitants of the indoor space.

The biggest and often the most coveted advantage of variable air volume systems is the fan control it incorporates. This fan control has evolved to serve the purpose of effective operation with even lower energy consumption. The newer models of electric fans can even serve as electric dampers in no small part due to their variable speed drives.

Incorporating a variable air volume system into one’s HVAC equipment is a necessity that accomplishes several goals. In the case that there is insufficient space to routinely incorporate the VAV system into a facility’s ductwork, flexible duct manufacturers can be called upon to correct this situation.
