How Air Cooled Chillers Work

You might wonder how an air-cooled chiller actually works. Here’s a quick breakdown. The chiller pulls heat from your process water in a closed loop. The chilled water moves through your equipment, picks up heat, and returns to the chiller. Inside the evaporator, the refrigerant absorbs this heat and turns into vapor. The compressor then squeezes this vapor into a high-pressure gas. Next, the gas flows to the condenser, where fans blow air over coils to cool it down. The refrigerant turns back into a liquid, drops in pressure and temperature, and starts the cycle again. This process keeps your system cool and running smoothly.
