A duct cooler distributes cool air to all the desired areas of a room or space by forcing the air through metal conduits at the proper pressure. Because the air is dispersed through one or more outlets and forced to a considerable distance from the fan via ducts, the management and flow of cool air from a duct air cooler are exemplary uniform.

PURPOSE OF DUCT AIR COOLERS: A GUIDE

• Cooling capacity and CFM: In both residential and commercial settings, duct air coolers offer consistent cooling across large areas. The cooling capacity of a duct cooler installed can range from 200 square feet to 2500 square feet, depending on its size. A duct cooler with a CFM of 1000–4000 is sufficient for a smaller area, but larger commercial spaces can use duct coolers with up to 30000 CFM. Using the CFM specifications listed, one can select the suitable duct cooler by performing a quick calculation of the affected space.

• Water Tank Capacity: While industrial duct coolers are commonly used, their water tanks are much larger, holding up to 700 liters of water. Duct air coolers, whether for the home or office, have a water tank capacity of 35–40 liters. Lower tank capacity, however, also fulfills the function of continuous water supply, which makes up for the duct cooler’s high water requirement because continuous water supply is a standard feature of duct coolers. This makes it possible for the duct air cooler to maintain a cooling effect over an extended period of time, which is particularly beneficial in industrial settings like factories, assembly lines, and manufacturing facilities where heat is continuously produced. A dependable water source that can supply continuous water supply during extended work hours must be connected to the water tank when Duct Coolers are installed on the wall or roof for centralized cooling. A duct cooler requires anywhere from 12 to 15 liters of water per hour to operate.

• Cooling Pads: Wood wool pads work well and are reasonably priced for smaller duct coolers. Still, when taking into account the benefits of centralized and uniform cooling in multiple spaces of a single premise (different rooms of a residential apartment or diverse spaces in a business unit), the cooling pads for duct air coolers must be of the highest caliber. Premium cellulose or honeycomb pads are widely used because of their huge evaporative capacity and significant water absorption capacity for more efficient cooling. These cooling pads are resistant to dust and simple to clean. These pads can be used for both residential and commercial purposes, and they range in price from 280 to 350 INR per square foot.

• Portability: The smaller Duct Air Cooler can be moved to any location on your property thanks to its movable and attachable wheels. Being portable, they are simple to use. The larger models, which are large capacity and high performance coolers, are typically mounted outside of your room or area and occasionally left open on the roof.

• Simple Upkeep and Installation Smaller duct coolers are extremely simple to install on windows, and because they are portable, it is simple to set them up on a balcony and perform maintenance as needed. However, although the installation of the Duct Cooler mounted on the wall or installed on the roof as part of centralized cooling is simple, technical assistance is needed. Since it takes a lot of time and effort to move a cooler once it is installed, it is important to choose the best location for the installation of a centralized cooling system in order to maximize the cooling effect in the area.

Because the body of a duct air cooler is composed of high-resistance, anti-corrosive metal, it requires little maintenance as long as the water tank, cooling pads, fan, and pump are cleaned appropriately and on a regular basis. In addition, the metal ducts are resistant to rust because they are constructed of galvanized steel; nevertheless, it is a good idea to regularly inspect the electrical parts, motor, and pump for any wiring problems. During the season, the cooling pads should be cleaned at least once every two months, or more frequently depending on usage volume and intensity.
