Introducing the innovative cascade refrigeration system by Qingdao Bingyan Refrigeration Equipment Co., Ltd. This cutting-edge system efficiently transfers heat load using CO2 and NH3 refrigerants, ensuring optimal cooling performance. The CO2 refrigerant absorbs heat in the end evaporator, which is then transferred to the high-temperature NH3 refrigerant in the condensing evaporator. The high-temperature NH3 refrigerant releases heat to the environment through the high-temperature condenser, completing the refrigeration cycle.
The condensed CO2 flows into the CO2 reservoir, then passes through the CO2 gas-liquid separator via the dryer filter and throttle valve. With the help of the CO2 circulation pump, the liquid CO2 is directed to the CO2 evaporator for efficient cooling. The gaseous CO2 is compressed by the compressor and returned to the condensing evaporator, ensuring a continuous cycle for optimal cooling performance.
