Introducing the innovative cascade refrigeration system by Qingdao Bingyan Refrigeration Equipment Co., Ltd. This cutting-edge system is specifically designed to efficiently manage heat transfer using a seamless combination of CO2 and NH3 refrigerants, ensuring peak cooling performance. In this advanced setup, CO2 refrigerant ingeniously absorbs heat in the end evaporator, subsequently transferring it to the high-temperature NH3 refrigerant within the condensing evaporator. The high-temperature NH3 refrigerant then adeptly releases heat to the environment via the high-temperature condenser, completing a sophisticated refrigeration cycle that promises efficiency and reliability.
The expertly condensed CO2 progresses into the CO2 reservoir, subsequently navigating through the CO2 gas-liquid separator, facilitated by the dryer filter and throttle valve. Supported by the CO2 circulation pump, liquid CO2 is channeled to the CO2 evaporator, ensuring efficient and consistent cooling. The gaseous CO2 is compressed by the compressor and efficiently rerouted to the condensing evaporator, maintaining a continuous cycle that guarantees optimal cooling performance through cutting-edge technology.
