A low-temperature freezer is a refrigeration equipment consisting of three major components: a refrigeration system, a water system, and an electrical system. The core is the refrigeration system, which is composed of a compressor, evaporator, condenser, and expansion valve. The water-cooled low-temperature freezer is because its condenser (radiator) is shell and tube type, which uses the water from the external cooling tower and cooling water pump to dissipate heat for the chiller. The core advantages of water-cooled low-temperature refrigerators are high energy efficiency, suitable for use in places with cooling water sources, low noise, etc
