What Is the Difference Between Evaporative Air Coolers and Conventional Air Conditioners? – Rundongfang

What is the difference between evaporative (eco-friendly) air coolers and conventional air conditioners? I believe many people are not quite clear about this question. Today, let us walk you through the differences in detail.

An evaporative air cooler is an environmentally friendly cooling unit that integrates cooling, ventilation, humidification, deodorization, and increased air oxygen content in one machine. It has no compressor and no refrigerant. The cooling medium is a wet pad evaporator (multi-layer corrugated fiber laminate). A circulation water pump continuously draws water from the bottom basin and sprays it evenly over the wet pad through a water distribution system, keeping the pad uniformly moistened from top to bottom. When the fan runs, it generates pressure that forces outside air through the evenly moistened wet pad. The heat in the air is fully absorbed as it contacts the water film on the wet pad, and the moisture is completely evaporated.

The cooling medium of a conventional air conditioner is refrigerant. Simply put, it achieves cooling by exploiting the properties of the refrigerant: converting from gas to liquid releases heat, while converting from liquid to gas absorbs heat. When the air conditioner is turned on, the compressor operates to put the evaporator (indoor unit) in an ultra-low pressure state, causing the liquid refrigerant in the evaporator to rapidly convert into gaseous refrigerant and absorb a large amount of heat. The air blown out by the air conditioner is cooled as it passes through the evaporator and then delivered into the room. After being pressurized by the compressor, the gaseous refrigerant condenses into liquid refrigerant in the high-pressure environment of the condenser (outdoor unit), releasing a large amount of heat, which is then dissipated by the outdoor fan.
