What is the cooling effect of evaporative air cooler? It is frequently asked over 20 years from the evaporative air cooler came out. As Air cooler don’t have the exact temperature and humidity control as air conditioner. So most customer worry about it before choose air cooler. Let’s see the test result.

 Industrial air coolers is also called ad evaporative air conditioners, use the principle of water evaporation to cool down. It is an energy-saving and environmentally friendly cooling air conditioner with no refrigerant, no compressor, and no copper pipes. The core component is water cooling pad (multi-layer corrugated fiber laminate), when the air cooler is turned on and running, negative pressure will be generated in the cavity, attracting hot outside air to pass through the cooling pad that is completely moistened by water, lowering the temperature and turning it into cool fresh air. The air outlet blows out to achieve a cooling effect with a temperature difference of about 5-12 degrees from the outside air. According to the meteorological data of Guangzhou (summer air conditioning outdoor calculation parameters, dry bulb temperature tw = 38 wet bulb temperature ts = 26.8 relative humidity φ = 53%). According to the meteorological conditions of Guangdong Province, XIKOO air cooler are calculated with a saturation efficiency of 85%. Cooling range of the air outlet (compared to outdoor): Δt = (tw-ts) × 85% = (36.8-26.8) × 85% = 9.5℃. From this we can see that. From this set of data, we can see that If the above conditions are met, the air cooler can achieve a temperature difference of 9.5°C.

Maybe you’re a bit confused by this explanation, so let’s use a few sets of real case measurement data to show it to you and you’ll understand:

The first set of data: the outdoor ambient temperature is 35°C and the air humidity is 40%, then the air outlet temperature after cooling and filtering of the air cooler is about 27°C;

The second set of data: the outdoor ambient temperature is 38°C and the air humidity is 35%, then the air outlet temperature after cooling and filtering of the industrial air cooler is about 27.5°C;

The second set of data: the outdoor ambient temperature is 41°C and the air humidity is 35%, then the air outlet temperature after cooling and filtering of the evaporative cooler is about 28°C;
