Industrial Air Cooler
What is evaporative air cooler?
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
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.
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.

RTFANS Air Cooler Advantage
Data for air exchange frequency in various places.
- Air exchange frequency(times/h)=total air flow rate(m³/h) ÷ indoor space volume.
- 20~30 times per hour for the general environment;
- 30~40 times per hour for the crowded public place;
- 40~50 times per hour for the workshop with heating equipment;
- 50~60 times per hour for a workshop with high temperature and high air pollution;
- Air exchange frequency can be increased in damp areas and decreased in dry places.
The way to calculate the cooler quantity needed.
- Cooler quantity needed = indoor space volume × air exchange frequency ÷ cooler air flow rate.
- Spot cooling projects shall vary based on the actual situation.
- The ducting system shall be matched with the air cooler model, and air outlet quantity shall be considered when designing.
Low investment and high efficiency.
Low power consumption, only 1 kWh per hour.
