Everything you need to know about air cooled chiller system

The air-cooled chillers are refrigeration system which can be used in both commercial and industrial facilities to cool fluid or dehumidify the air. It can be used in a wide variety of settings such as hotels, corporate events, restaurants, sporting events, large-scale buildings, industrial and manufacturing plants and many more. The air-cooled chillers are available in portable sizes as well which can be used in events or permanent infrastructure. They are compact in size and can be highly efficient. It is easy to install and remove it as well which makes it ideal for temporary and emergency applications. While the water-cooled chillers are known to be more efficient than an air-cooled chiller, they are still worth it and make a better option.


How the air-cooled chiller system function?

The air-cooled chillers absorb heat from process water and transfer this heat into the air around the chiller. Such units are typically used in areas where additional heat discharge is not an issue and can be used as an advantage. The additional heat can be used to warm the place during winter for less money than getting a traditional heating system.

It is a cycle which starts with the evaporator and has a liquid refrigerant which flows over the evaporator tube where it gets evaporated. In this process, the heat is absorbed from the chilled water and circulated through the bundle. The compressor pulls the refrigerant vapor from the evaporator. The compressor is then tasked with pumping the refrigerant vapor into the condenser which helps increase temperature and pressure. The refrigerant then condenses in the condenser tube which releases internal heat to the air or cooling water. The high-pressure liquid moves through the expansion device and goes into the evaporator which reduces the refrigerant pressure and temperature. The cycle ends when the refrigerant flows back over the chilled water coils to absorb more heat. This is a continuous cycle that keeps ongoing.

How are air-cooled and water-cooled chillers different?

The water and air-cooled chiller work in a similar manner. They each consist of the evaporator, compressor, condenser, and expansive valve. The only major difference between the two is that one uses air to fuel the condenser while the other uses water to do so.

  • The air-cooled chiller is easier to maintain and less expensive when it comes to basic maintenance in order to keep it functioning at optimum levels.

  • The air-cooled chillers don’t require a condenser water pump or a cooling tower.

  • The air-cooled chillers are known to consume 10% more power compared to a water-cooled one as the wet surfaces are better for transferring heat than dry surfaces.

Types of air-cooled chillers 

There are basically two types of air-cooled chiller which are stationary chillers and portable chillers.
The stationary chillers are used when there is no issue if excess heat is being generated. The portable ones are just stationary and used for temporary purposes.


The air-cooled chillers are mostly located in mechanical equipment rooms or areas of the building which are close to the spot that needs to be cooled. In some settings, they are kept right next to the area which requires cooling and it is also based on the size of the chiller and compressor. In some cases, the chillers are even placed outdoors.
