What is difference between air cooled chiller and water cooled chiller? Dec 18, 2021

Water cooled chillers are usually installed indoors and consist of a separate circulating cooling water condenser and connected to an outdoor cooling tower.

The air cooled chiller is used for outdoor installation. The air-cooled chiller is connected to a finned heat exchanger for cooling.

The air cooled chiller contains a heat preservation water tank and a water pump in its body, and there is no need to add a cooling water tower to dissipate heat. It is very convenient to install and move. But it has higher requirements for the working environment. First of all, because it is a hot air circulation It is refrigerated, so if the ventilation effect of the installation workshop is not good, it will directly affect the cooling effect of the chiller. In addition, if you want to put the chiller in a dust-free workshop with humidity requirements, then I advise you to modify it Water-cooled. Because the air cooled chiller will spray water vapor on the top of the machine to dissipate heat.

Water cooled chillers can be divided into open type, sealed type (some called box type) and screw type. First of all, it is necessary to state that for water-cooled chillers, additional cooling towers and water pumps must be installed to extract hot water and dissipate heat. In order to achieve effective cooling effect.

The open-type chiller needs to be equipped with an additional water tank. The sealed type is not necessary, because it has a built-in water tank. The open-type chiller is usually installed somewhere outside the workshop. It is convenient for maintenance, but because it is not beautiful enough, it is A sealed Water cooled chillers was produced. Because it is a box structure, it is more popular. But if you have very high requirements for cooling capacity, you must choose a screw-type chiller.

Air cooled chiller can be used in small systems, and most of the large chillers are water-cooled chillers. The initial investment of water-cooling is a little less than that of air-cooling in terms of the main engine. In terms of long-term operation, the cooling efficiency of water-cooling units will relatively decrease, while air-cooling will not.

The air cooled chiller adopts the air cooling method, eliminating the need for cooling towers, cooling water pumps and piping systems that are essential for cooling water systems, avoiding condenser fouling and water pipe blockage in areas with poor water quality, and also saving water resources. Among the current cold water air-conditioning equipment products, maintenance and repair are the most economical and simple models.
