Introducing the groundbreaking cascade refrigeration system by Qingdao Bingyan Refrigeration Equipment Co., Ltd. This advanced system masterfully harnesses the power of CO2 and NH3 refrigerants to deliver unmatched cooling performance. The CO2 refrigerant adeptly absorbs heat in the end evaporator, seamlessly transferring it to the high-temperature NH3 refrigerant in the condensing evaporator. Subsequently, the high-temperature NH3 refrigerant efficiently releases heat to the environment through the high-temperature condenser, thus completing a highly efficient refrigeration cycle.
The condensed CO2 is skillfully directed into the CO2 reservoir, passing through the CO2 gas-liquid separator via the dryer filter and throttle valve. Propelled by the CO2 circulation pump, the liquid CO2 is efficiently channeled to the CO2 evaporator, optimizing cooling. Meanwhile, the gaseous CO2 is expertly compressed by the compressor and returned to the condensing evaporator, ensuring a seamless, continuous cycle for unparalleled cooling performance.
