Introducing an innovative leap in cooling technology from Qingdao Bingyan Refrigeration Equipment Co., Ltd.—the groundbreaking cascade refrigeration system that epitomizes the fusion of innovation and efficiency. This cutting-edge technology seamlessly orchestrates the transfer of heat load by ingeniously combining CO2 and NH3 refrigerants. This synergy guarantees unmatched cooling prowess. The cooling process is initiated as CO2 refrigerant absorbs heat in the end evaporator. This absorbed heat is ingeniously transferred to the high-temperature NH3 refrigerant within the condensing evaporator. The cycle reaches its apex as the high-temperature NH3 refrigerant releases heat efficiently to the environment through the high-temperature condenser, achieving a seamless and flawless refrigeration cycle.
The cooling symphony continues as condensed CO2 transitions into the reservoir, embarking on a journey through the CO2 gas-liquid separator, enhanced by the advanced dryer filter and throttle valve. Through the exceptional capabilities of the CO2 circulation pump, liquid CO2 is expertly directed to the CO2 evaporator, ensuring precise and impeccable cooling. Simultaneously, gaseous CO2 is adeptly compressed by the compressor and reintroduced to the condensing evaporator, fostering a continuous cycle engineered for peak cooling performance and efficiency.
