Description by Manufacturer

RDF Evaporative air cooler small conditioner used for warehouse

Industrial Air Cooler differs from typical air conditioning systems, which use vapor-compression or absorption refrigeration cycles.

Product details

Product Keywords

small air conditioner,royal air cooling fan,rotating air cooler

HVLS fans move slowly and distribute large amounts of air at low rotational speed– hence the name "high volume, low speed."

RDF Evaporative air cooler small conditioner used for warehouse

Evaporative Air Cooler

Evaporative Air Cooler designed by RDF are professional strong plastic structured models with axial fan, which needs to be installed with air ducting system. Fixed installation model is appropriate to be installed on solid places such as outside wall, grounds, concrete or Zinc-steel structured roof. Target Applications: Workshops, Factories, Supermarket, School&Church, Entertainment Centers.

COOLING PRINCIPLE

As schematically shown, when the cooler is working, water is pumped from the tank to the water distributor, and distributed evenly to the vaporative cooling pads, then go back to the tank. Meanwhile, the outside hot air is drawn through the?wetted cooling pads and filtered and reduced in temperature before delivering to the user spaces.

WORKING PRINCIPLE

Filtered and cooled by an evaporative air cooler, the outdoor fresh air is continuously sent into the indoor space through the air duct and air supply outlets. 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 cool, ventilated, clean and comfortable environment. Suitable exhaust area and effective exhaust are essential for satisfactory performance of any evaporative air cooling system.

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.

ADVANTAGES

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 general environment;
30~40 times per hour for crowded public place;
40~50 times per hour for workshop with heating equipment;
50~60 times per hour for 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 varies based on actual situation.
The ducting system shall be matched with the air cooler model, and air outlet quantity shall be considered when designing.
