Introducing the groundbreaking cascade refrigeration system crafted by Qingdao Bingyan Refrigeration Equipment Co., Ltd. This state-of-the-art system is designed to deliver superior thermal management by ingeniously leveraging CO2 and NH3 refrigerants. Our innovative approach ensures exceptional cooling performance. The CO2 refrigerant ingeniously absorbs heat in the end evaporator, transferring it to the high-temperature NH3 refrigerant in the condensing evaporator. This NH3 refrigerant then expertly releases the accumulated heat to the surroundings through the high-temperature condenser, thus completing a seamless refrigeration cycle.
Once condensed, CO2 flows into the CO2 reservoir, then skillfully navigates through the CO2 gas-liquid separator thanks to the dryer filter and throttle valve. The CO2 circulation pump plays a pivotal role in directing the liquid CO2 to the CO2 evaporator, ensuring efficient cooling. The gaseous CO2 is then expertly compressed by the compressor and directed back to the condensing evaporator, ensuring a consistently efficient cycle for unmatched cooling performance.
Experience unparalleled cooling efficiency and steadfast reliability with the cascade refrigeration system offered by Qingdao Bingyan Refrigeration Equipment Co., Ltd. Revolutionize your refrigeration setup now!
