Introducing the groundbreaking cascade refrigeration system by Qingdao Bingyan Refrigeration Equipment Co., Ltd. This state-of-the-art system is engineered to seamlessly manage heat load using the powerful CO2 and NH3 refrigerants, ensuring an unmatched cooling experience. The CO2 refrigerant expertly absorbs heat within the end evaporator, which is then skillfully transferred to the robust high-temperature NH3 refrigerant in the condensing evaporator. The high-temperature NH3 refrigerant effectively releases heat into the environment through the high-temperature condenser, thus completing the efficient refrigeration cycle.
The condensed CO2 is meticulously guided into the CO2 reservoir, before making its way through the CO2 gas-liquid separator via a sophisticated dryer filter and throttle valve. Thanks to the efficient CO2 circulation pump, the liquid CO2 is channeled into the CO2 evaporator, delivering exceptional cooling capabilities. Subsequently, the gaseous CO2 is compressed by the compressor and returned to the condensing evaporator, ensuring a seamless cycle for peak cooling performance.
