Introducing the revolutionary cascade refrigeration system by Qingdao Bingyan Refrigeration Equipment Co., Ltd. This state-of-the-art system masterfully manages heat transfer using the dynamic duo of CO2 and NH3 refrigerants, delivering unmatched cooling efficiency. The CO2 refrigerant adeptly captures heat in the terminal evaporator, which is then seamlessly transferred to the robust high-temperature NH3 refrigerant within the condensing evaporator. Through the high-temperature condenser, the NH3 refrigerant gracefully dispels heat into the environment, flawlessly completing the refrigeration cycle.
Chilled CO2 makes its way into the CO2 reservoir, navigating through the CO2 gas-liquid separator, dryer filter, and throttle valve with precision. The CO2 circulation pump energetically propels the liquid CO2 toward the CO2 evaporator, ensuring a supreme cooling process. Simultaneously, the gaseous CO2 is expertly compressed by the compressor and returned to the condensing evaporator, sustaining a seamless cycle for peak cooling performance.
