Air Source Chiller and Water Source Chiller

Air Source Chiller and Water Source Chiller

As we all know, industrial chillers can often be divided into two types: air source chiller and water source chiller due to different cooling methods. Different cooling methods will lead to different effects of the chiller. So do you know the difference between these two chillers?

air source chiller:

The air source chiller uses a shell-and-tube evaporator to exchange heat between water and refrigerant. After the refrigerant system absorbs the heat load in the water and cools the water to produce cold water, the heat is brought to the finned condenser by the action of the compressor. The cooling fan is lost to the outside air.

water source chiller:

The water source chiller uses the shell-and-tube evaporator to exchange heat between water and the refrigerant. After the refrigerant system absorbs the heat load in the water and cools the water to produce cold water, the heat is brought to the shell-and-tube condenser by the action of the compressor. The heat is exchanged with water, so that the water absorbs the heat and then takes it out of the external cooling tower through the water pipe to dissipate it.

The difference between the two:

The difference between air source chiller and water source chiller is mainly in the difference of the condenser. The air source chiller uses a fan for heat dissipation. Finned condensers are usually used. Fins actually refer to aluminum sheets. The parts that need heat exchange are installed externally to achieve high-efficiency heat dissipation, and then the hot air is drawn out by a powerful fan. The condenser of the water source chiller mainly removes heat by circulating cooling water, so the condenser of the water source chiller is also commonly called a water cannon.

The content introduced above is the two cooling methods of industrial chillers. Generally, if the heat generation is small, use air cooling, and if the heat generation is large, use water cooling, because the cooling water temperature of water source chiller can be controlled, but air cooling cannot control the cooling temperature, and the noise will be relatively large, so The cooling method of water cooling has become the cooling choice of many industrial equipment.
