Best evaporative air&swamp cooler.

Evaporative air cooler system functions by introducing vapor into the atmosphere, which helps to lower the temperatures. The thought of swamp cooler is a phenomenon, which regularly happens just about all over in our surroundings. Best air coolers offer a cheap, environmentally-friendly suggests that of keeping areas fresh, Water and made air square measure combined.

    1. Coolers square measure created with a micro-computer programmed panel with show LCD and are available with the conventional device.
    2. The internal timer permits cooler to be programmed to show on or shut off at preselected times.
    3. Conjointly enclosed is Associate in Nursing Auto-Shutoff feature for pump motor once water levels drop below the limit.
    4. 30" diameter fan operates at three selectable speeds.
    5. A thick cooling pad ensures reliable heat absorption.
    6. Four rubber casters with brakes permit pure portable evaporative cooler quality.

What is an evaporative cooler?

The evaporative air cooler mainly uses the principle of water evaporation effect to realize the cooling by the physical method. Since the evaporative cooler does not use the compressor, excessive emission of "Freon" in the environment is well solved.Utilizes the evaporative cooling pad(wet curtain) as a cooling medium, the water flows uniformly and slowly from the top, through the corrugated surface, until the cooling pad wetted thoroughly. Moreover, when the regular operation of the fan generates pressure, the fresh outdoor air is forced to wear. So that the dry, hot air becomes a soft, fresh air, and at the same time, the air humidity can be increased, thereby reducing the temperature and humidifying.

What is an evaporative cooler

What is the basic working principle of air cooler?

basic working principle

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 odour 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 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.

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 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.
