FAQs
How does an air chiller work?

An air-cooled industrial chiller is a refrigeration system that cools fluids and works in tandem with your facility's HVAC system. It has four main parts: an evaporator, compressor, condenser and expansion valve. It works by absorbing heat from processed water. Heat transfers away from the water using the chiller's evaporator. Liquid refrigerant evaporates as it moves over the evaporator tube, creating a low-pressure gas. Next, the evaporated refrigerant travels to the compressor, where the low-pressure gas compresses into a high-pressure gas. The gas then leaves and goes to the air-cooled condensers. While in the condenser, heat is removed from the chiller by being blown outside through fans on the side of the condenser. After the gas leaves the condenser, the refrigerant changes into a high-pressure liquid. The high-pressure liquid travels to the evaporator through the expansion valve. Because an air-cooled chiller works continuously, this low-pressure liquid transfers back to the evaporator, where the cycle repeats itself.

What is the difference between an air-cooled chiller and a water-cooled chiller?

Water-cooled and air-cooled chillers work similarly. They both have an evaporator, compressor, condenser and expansion valve. The main difference is that one uses air to fuel condenser cooling and the other uses water. Air chillers are the preferred choice, especially in cases where water access is limited.

Is an air-cooled chiller more efficient than a water-cooled chiller?

Water-cooled chillers are more efficient because they condense using the ambient wet bulb temperature, which is lower than the air chillers' ambient dry bulb temperature. The lower the temperature a chiller condenses, the more efficient it is. However, air-cooled chillers are less costly and easier to maintain than water-cooled chillers.
