Introducing the revolutionary cascade refrigeration system by Qingdao Bingyan Refrigeration Equipment Co., Ltd. This state-of-the-art system is engineered to deliver unparalleled cooling performance by effectively transferring heat load using CO2 and NH3 refrigerants. The CO2 refrigerant masterfully absorbs heat in the end evaporator. This absorbed heat is subsequently transferred to the high-temperature NH3 refrigerant in the condensing evaporator. The high-temperature NH3 refrigerant then expertly releases heat to the environment through the high-temperature condenser, completing the refrigeration cycle with precision.
The condensed CO2 gracefully flows into the CO2 reservoir, journeying through the CO2 gas-liquid separator via the dryer filter and throttle valve. Empowered by the CO2 circulation pump, the liquid CO2 is expertly directed to the CO2 evaporator for outstanding cooling. The gaseous CO2, compressed by the compressor, is returned to the condensing evaporator, assuring a seamless and continuous cycle for superior cooling performance.
