The refrigerating circulator has a refrigerating temperature range from -125 degrees to -20 degrees, and adopts a computer cascade type temperature controller and a PT100 temperature sensor for high temperature control accuracy. The product adopts ethylene glycol mixed with water for circulating refrigeration to save water resources; supercooling technology is used to ensure the stability of temperature at low temperatures; fully enclosed design is used to ensure the purity of cold and heat-conducting media, prevent ice crystals, and increase the life of heat-conducting fluids;
working principle:
1. The chilled water pump of the water storage tank continuously circulates through the plate or grid evaporator;
2. After the compressor is running, it is subjected to suction-compression-exhaust-condensation (liquefaction) -throttling-then the evaporator absorbs heat and vaporizes at a low temperature of -10 to -18 degrees in the evaporator. The chilled water is at a water temperature of 0 degrees. The ice layer continually condenses on the surface of the evaporator at a lower temperature. When the ice layer condenses to a certain thickness, the evaporation temperature of the refrigerant reaches a temperature-controlled set temperature, and the defrost solenoid valve is often connected in the form of a heat pump De-icing. Realize the next cycle.
