Introducing the groundbreaking cascade refrigeration system by Qingdao Bingyan Refrigeration Equipment Co., Ltd. This state-of-the-art system is engineered to maximize efficiency in heat transfer through the dynamic use of CO2 and NH3 refrigerants, delivering unparalleled cooling performance. The CO2 refrigerant adeptly absorbs heat in the end evaporator, seamlessly transferring it to the high-temperature NH3 refrigerant within the condensing evaporator. The high-temperature NH3 refrigerant skillfully releases heat to the environment via the high-temperature condenser, thus completing the sophisticated refrigeration cycle.
The condensed CO2 gracefully flows into the CO2 reservoir, and then seamlessly navigates through the CO2 gas-liquid separator, enhanced by the dryer filter and throttle valve. With the precise action of the CO2 circulation pump, the liquid CO2 is efficiently directed to the CO2 evaporator, achieving remarkable cooling. The gaseous CO2 is expertly compressed by the compressor and then returned to the condensing evaporator, ensuring a seamless and continuous cycle, thereby delivering optimal cooling performance.
Discover the unparalleled cooling efficiency and rock-solid reliability offered by the cascade refrigeration system from Qingdao Bingyan Refrigeration Equipment Co., Ltd. Elevate your refrigeration setup to new heights of performance today!
