Water-cooled chillers are a common type of refrigeration equipment. They mainly use cooling water as a cold source to achieve air conditioning and refrigeration needs through the principle of evaporative refrigeration.

its working principle is mainly divided into four parts: refrigeration cycle, condensation cycle, cooling water cycle, and electronic control system.

refrigeration cycle is the core part of refrigeration, including compressor, evaporator, throttle valve and other important components. The working principle of the refrigeration cycle is to compress the low-temperature and low-pressure refrigerant into high-temperature and high-pressure refrigerant through a compressor, and then enter the evaporator. Using the principle of evaporative refrigeration, the coolant contacted by air or water is cooled. The throttle valve is mainly used to control the refrigerant flow, thereby adjusting the cooling effect. The condensation cycle part of the

is mainly to discharge the heat absorbed in the evaporator through the condenser, and its main components are the condenser, fan, etc. The working principle of the condensation cycle is to cool the high-temperature and high-pressure refrigerant through the condenser, thereby discharging the absorbed heat through the condenser. Among them, the fan mainly provides forced convection to speed up the heat dissipation of the refrigerant. The cooling water circulation part of the

mainly transfers the cold water to the inside of the evaporator through the water pump and contacts the refrigerant to achieve the cooling effect. Its main components are water pumps, cooling towers, etc. Among them, the cooling tower is mainly used to cool the cooling water circulating by the water pump by natural wind cooling. The

electronic control system is the core part of controlling the entire water-cooled chiller, including temperature probes, computer control, pressure control and other components. The electronic control system controls the compressor, water pump and other operating equipment through the computer by monitoring and feedback the temperature, pressure and other parameters in the refrigeration cycle, so as to realize the optimal operation of the entire unit.

Generally speaking, the working principle of water-cooled chillers is relatively complex, and multiple parts need to cooperate to achieve efficient cooling effect. When selecting and using water-cooled chillers, it is necessary to select the appropriate model and configuration according to specific needs to ensure its stability and reliability during use.
