Introducing the groundbreaking cascade refrigeration system by Qingdao Bingyan Refrigeration Equipment Co., Ltd.! This state-of-the-art system masterfully manages heat transfer using CO2 and NH3 refrigerants, delivering unparalleled cooling performance. In this ingenious process, the CO2 refrigerant efficiently absorbs heat in the end evaporator, which is then seamlessly transferred to the high-temperature NH3 refrigerant within the condensing evaporator. The high-temperature NH3 refrigerant effectively releases heat to the surroundings through the high-temperature condenser, thereby completing the sophisticated refrigeration cycle.
The condensed CO2 is skillfully directed into the CO2 reservoir, and then progresses through the CO2 gas-liquid separator via the meticulously engineered dryer filter and throttle valve. Empowered by the CO2 circulation pump, the liquid CO2 is channeled to the CO2 evaporator, ensuring remarkable cooling efficiency. Meanwhile, the CO2 gas is compressed by the robust compressor and returns to the condensing evaporator, guaranteeing an uninterrupted cycle for exceptional cooling performance.
