How to choose air cooled water chiller or water cooled water chiller?

Water chiller takes heat from processing circulating water, and the heat is discharged to the water resource or the air outside. This type of  chiller system features high efficiency and also widely in many applications.

A chiller consists of the following six main components:

1. Compressor – takes this gas and increases its pressure so that ambient air or water can remove the heat.

2. Condenser – rejects heat gained by the gas using ambient air or cooling tower water to condense the gas back to a liquid for use again by the evaporator.

3. Water tank – holds the circulating coolant, usually water, water tank is sized large enough to prevent turbulent flow in tank causing pump cavitation.

4. Pump – circulates coolant from the holding tank to the evaporator and from the evaporator to the machine or process being cooled and back to the tank.

5. Control Panel – set temperature, compressor contactor, pump starter, 3-phase fuses, control transformer, safety controls, run and fail lights.

6. Evaporator – cools the water, water or air by transferring the heat to a refrigerant which is turned into a gas.

The max difference is the way of heat radiation from air cooled chiller with water cooled chiller.

Air cooled chiller adopts the finned aluminum with fans. The air cooled chiller is a good choice if your factory ventilation and heat dissipation is well and ambient temperature is not higher than 35deg.C. It is very practical and convenient to use.

Water cooled chiller adopts the shell and tube condenser. It needs equipped with the cooling tower for use. That means you need to do some extra work on connect pipes. The water cooled chiller have good cooling effective and higher cooling capacity than air cooled chiller under the same power consumption.
