Air to Water Chiller-An Ultimate Buying Guide by TopChiller.

An Air to Water Chiller absorbs the heat from the process water; the waste heat then travels from the chilled water to the air around it.

Different types of refrigeration circuits in an Air to Water Chiller can be customized according to the requirements of different applications.

Air to Water Chiller is provided with partially assembled components such as filter drier, compressor, fan, expansion valve, condenser, and heat exchanger.

It is made up of copper and aluminum because of its excellent thermal properties; It is lightweight as its tubes are made of plastic.

What is an Air to Water Chiller?

An Air to Water Chiller is a refrigeration machine that is used to extract heat from the system and eject the heat into the atmosphere.

It is a refrigeration system that uses a fan and is commonly used in power plants. You can also cool down fluids while using this device with the help of air handling equipment.

The temperature for an Air-Water Chiller is mostly room temperature. Generally, the minimum room temperature is about -12 degrees and the maximum is 57 degrees.

You can determine the electrical power demand of the Air to Water Chiller in Kilowatts.

An Air to Water Chiller consumes more energy than water-cooled chillers. It doesn’t need cooling towers.

It is preferably required in areas where the water supply is expensive or irregular.

The Air condenser of this device plays an important role by cooling the air blown into it.

It is suggested to set up your Air to Water Chiller outdoors to increase the efficiency of your device. It is preferable for large-scale applications.

An Air Water Chiller doesn’t need to be set up near the constant availability of water. It can be installed anywhere outdoors where there is a proper power supply available.

What are the Working Principles of Air to Water Chiller?

An Air to Water Chiller is used to provide cooling in various industrial applications. Here is how it works.

  1. Heat Absorption Process:

An Air to Water Chiller starts its working from the process of heat absorption. In this process, the heat from the water is absorbed.

  1. Air Handler System:

The air handler system ejects the hot air used by the system out into the atmosphere.

  1. Evaporator:

In the process of evaporation, the air is blown into the atmosphere by an evaporator that air was infused into the process.

  1. Liquid Refrigerant:

In this step, the fluid from the evaporator is turned into a gas state that has low pressure.

  1. Compression:

In this process of Air to Water Chiller, the low-pressure air from the evaporator is compressed to increase the volume of its pressure.

  1. Condensation:

During the condensation process of an Air Water Chiller, the fans are used as heat exchangers to blow hot air out and clean air inside the system.

To ensure the optimum working, it is suggested to install it outdoor.

The main process in the working is the conversion of low-pressure liquid to high pressure by the refrigerant.

The process continues until it reaches the desired cooling temperature.

What are the Main Components of the Air to Water Chiller?

An Air to Water Chiller is specially designed from branded high-quality components to provide efficient cooling in different applications.

The main components of an Air Water Chiller are appended below;


The compressor of this refrigeration system acts as a driving force. Different types of compressors include scroll, screw, centrifugal and reciprocating compressors.

What are the Main Features of Air to Water Chiller?

The following features make it unique from others.

  • The cooling capacity is a useful feature. An Air to Water Chiller can extract the heat from the water under process is called the cooling capacity.

It can be measured in Kilowatts or Tons of Refrigeration (TR).

  • The process flow feature refers to the flow capacity of the pump in an Air to Water Chiller.
  • The fluid discharge is the required temperature for the dissipation of liquid discharge.

This feature shows the quantity of heat absorbs by the overall chilling process.

  • The Process pressure feature is the accumulative stress of the pump.
  • Another feature is known as reservoir capacity. It keeps the liquid has the units in gallons.
  • The Power source provides the specifications of the phase, voltage, and frequency.
  • It has high-performance compressors and a sleeve-type air-cooled condenser.
  • It has a low noise fan motor with high stability and an excellent anti-rust treatment.
  • It is easy for the operator, install and maintain.

How an Air Condenser in Air to Water Chiller is different from a Water Condenser?

The air condenser in Air to Water Chiller is different from a water condenser in terms of its method of heat dissipation.

An Air condenser uses ambient air to lower the temperature of a hot refrigerant. It is very much similar to the car radiator or air conditioner condensers.

The refrigerant flowing through different tubes has mechanically joined with an array of spaced fins in small distances.

An Air condenser fan blows the air through those fins and outside of the tube by lowering the refrigerant flowing through the tubes.

Most of the heat is removed into the air. This heat can be recovered for further use.

On the other hand, a water condenser uses water as a source of cooling the refrigerant. The water condenser may be a tube in shell, tube in tube, or plate-type heat exchanger.

The refrigerant and the cooling water travel separately in heat exchangers. The water that is flowing over the refrigerant tubes absorbs a large amount of heat.

In short, an Air condenser of an Air to Water Chiller simply performs the heat dissipation process of condensation by using air as a medium. While the water condenser uses water for this purpose.
