Introducing the groundbreaking cascade refrigeration system by Qingdao Bingyan Refrigeration Equipment Co., Ltd. This state-of-the-art system revolutionizes heat load transfer by ingeniously utilizing CO2 and NH3 refrigerants, guaranteeing unparalleled cooling performance. Within this system, the CO2 refrigerant efficiently absorbs heat in the end evaporator. This absorbed heat is then seamlessly transferred to the high-temperature NH3 refrigerant within the condensing evaporator. The NH3 refrigerant, now at an elevated temperature, expertly releases heat to the environment via the high-temperature condenser, thus completing an efficient and effective refrigeration cycle.
The condensed CO2 seamlessly flows into the CO2 reservoir, subsequently passing through the CO2 gas-liquid separator with precision, aided by the dryer filter and throttle valve. Through the dynamic action of the CO2 circulation pump, the liquid CO2 is expertly directed to the CO2 evaporator, where it provides exceptional cooling. The gaseous CO2 is then precisely compressed by the compressor and skillfully returned to the condensing evaporator, ensuring a continuous, uninterrupted cycle that delivers optimal cooling performance at all times.
Discover the ultimate in cooling efficiency and reliability with the cascade refrigeration system from Qingdao Bingyan Refrigeration Equipment Co., Ltd. Elevate your refrigeration setup to new heights of performance today!
