Chiller is a kind of water cooling equipment that can provide constant temperature, constant flow and constant pressure. The principle of the chiller is to inject a certain amount of water into the internal water tank of the machine, cool the water through the chiller refrigeration system, and then use the water pump inside the machine to inject low-temperature frozen water into the equipment that needs to be cooled. The chilled water transfers the heat inside the machine. Take it away and return the high-temperature hot water to the water tank for cooling. This cycle exchanges cooling to achieve the cooling effect of the equipment.
Chillers can be divided into air-cooled chillers and water-cooled chillers.
The air-cooled chiller uses a shell and tube evaporator to exchange heat between water and refrigerant. The refrigerant system absorbs the heat load in the water and cools the water to produce cold water. The heat is brought to the fin condenser through the action of the compressor. Then it is lost to the outside air by the cooling fan (wind cooling).
The water-cooled chiller uses a shell-and-tube evaporator to exchange heat between water and refrigerant. The refrigerant system absorbs the heat load in the water and cools the water to produce cold water. It then brings the heat to the shell-and-tube condenser through the action of the compressor. The refrigerant exchanges heat with water, causing the water to absorb heat and then take the heat out of the external cooling tower through the water pipe for dissipation (water cooling).
The cooling effect of the condenser of the air-cooled chiller is slightly affected by seasonal climate changes in the external environment, while the water-cooled chiller uses a water tower to dissipate heat more stably. The disadvantage is that it requires a water tower and has poor mobility.
