Evaporative Air Cooler Manufacturer.

Evaporative air coolers often used to cool Open Spaces in production workshops or warehouses.

Industrial Air Cooler

A high-volume low-speed (HVLS) fan is a type of mechanical fan higher than 7 feet (2.1 m) in diameter. HVLS fans are generally ceiling fans, although some are pole mounted. HVLS fans move slowly and distribute large amounts of air at low rotational speed– hence the name “high volume, low speed.” These fans have very low revolutions per minute as compared to other fans. But due to their large size, they can provide a high volume of air at low speed.

The size of these fans can vary from 2.8m (8ft) to 7.3m (24ft). There is their diameter from one tail to another. Moreover, they have a different aerodynamic design as well. The blades are not like regular fans, and they have a unique aerodynamic design. The number of blades is also more than ordinary fans. RTFANS all huge HVLS fans have six blades and a patented airfoil design for better strength and flexibility.

What is evaporative air cooler?

An industrial evaporative air cooler (also called a swamp cooler, desert cooler) is a device that cools air through water evaporation, often used to cool Open Spaces in production workshops or warehouses. Evaporative cooling applies the fact that water absorbs heat to evaporate. The temperature of dry air can be dropped significantly through the phase transition of liquid water to water vapor (evaporation). It can cool air using much less energy than refrigeration. In arid climates, evaporative air cooler has the added benefit of humidifying and more moisture to space.

The cooling potential for evaporative cooling is dependent on the wet-bulb depression, the difference between dry-bulb temperature and wet-bulb temperature (see relative humidity). In arid climates, evaporative cooling can reduce energy consumption and total equipment for conditioning as an alternative to compressor-based cooling.

What is the basic working principle of air cooler?

Filtered and cooled by an evaporative air cooler, the fresh outdoor air is sent into the indoor space through the air duct and air supply outlets continuously. With the continuous supply of fresh air, the indoor space is in a positive pressure condition. Thus the original hot air containing odor and dust will be emitted out of the room, resulting in a fresh, ventilated, clean, and comfortable environment. Suitable exhaust area and active exhaust are essential for the satisfactory performance of any evaporative air cooling system.

Air Cooler Relative Humidity

This zone is not applicable as in reality when the temperature is relatively high, RH is predominantly lower than the supply air temperature.With the wind-chill effect, the effective temperature for thermal human comfort is 1~2℃ lower than the Supply Air Temperature.
