Introducing the state-of-the-art cascade refrigeration system by Qingdao Bingyan Refrigeration Equipment Co., Ltd.! This groundbreaking system masterfully manages heat transfer using top-tier CO2 and NH3 refrigerants, ensuring remarkable cooling performance. Witness the CO2 refrigerant efficiently absorb heat in the end evaporator, which is subsequently transferred to the high-temperature NH3 refrigerant in the condensing evaporator. Completing this sophisticated cycle, the high-temperature NH3 refrigerant skillfully releases heat to the environment via the high-temperature condenser.
Witness the seamless flow as the condensed CO2 enters the CO2 reservoir, proceeding through the CO2 gas-liquid separator, expertly filtered and managed via the dryer filter and throttle valve. The reliable CO2 circulation pump propels the liquid CO2 to the CO2 evaporator, achieving impeccable cooling. The gaseous CO2 is then adeptly compressed and returned to the condensing evaporator, ensuring a flawlessly continuous cycle for unparalleled cooling performance.
Elevate your cooling experience to new heights with the superior efficiency and unmatched reliability of the cascade refrigeration system from Qingdao Bingyan Refrigeration Equipment Co., Ltd. Transform your refrigeration setup into a pinnacle of modern cooling technology today!
Advantages of NH3/CO2 Cascade Refrigeration System
Features:
