Introducing the revolutionary cascade refrigeration system from Qingdao Bingyan Refrigeration Equipment Co., Ltd. This state-of-the-art system masterfully manages heat load transfer utilizing the robust capabilities of CO2 and NH3 refrigerants, guaranteeing unparalleled cooling performance. The process begins with the CO2 refrigerant absorbing heat in the end evaporator, which is then expertly transferred to the high-temperature NH3 refrigerant within the condensing evaporator. The high-temperature NH3 refrigerant then efficiently releases heat to the environment through the high-performance high-temperature condenser, completing the sophisticated refrigeration cycle with precision and reliability.
The condensed CO2 seamlessly flows into the CO2 reservoir, proceeding through the CO2 gas-liquid separator with the help of the dryer filter and throttle valve. Thanks to the proficient CO2 circulation pump, liquid CO2 is directed to the CO2 evaporator, ensuring efficient and effective cooling. The gaseous CO2 is expertly compressed by the compressor and returned to the condensing evaporator, maintaining a continuous cycle and ensuring optimal cooling performance with every cycle.
Unlock superior cooling efficiency and unmatched reliability with the cascade refrigeration system crafted by Qingdao Bingyan Refrigeration Equipment Co., Ltd. Elevate your refrigeration setup to the next level today and experience the difference!
Advantages of NH3/CO2 Cascade Refrigeration System
