Introducing the revolutionary cascade refrigeration system by Qingdao Bingyan Refrigeration Equipment Co., Ltd. - a marvel of modern engineering. This state-of-the-art system deftly manages heat transfer using a meticulously balanced combination of CO2 and NH3 refrigerants, delivering unparalleled cooling performance. In this sophisticated process, the CO2 refrigerant adeptly absorbs heat in the end evaporator. This absorbed heat is then skillfully transferred to the high-temperature NH3 refrigerant within the condensing evaporator. The NH3 refrigerant, now imbued with absorbed heat, efficiently releases this heat to the surrounding environment through the high-temperature condenser, thereby completing an efficient and elegant refrigeration cycle.
The condensed CO2 seamlessly flows into the CO2 reservoir and journeys through the CO2 gas-liquid separator, aided by the dryer filter and throttle valve. This journey is propelled by the CO2 circulation pump, which directs the liquid CO2 to the CO2 evaporator, ensuring robust and effective cooling. Meanwhile, the gaseous CO2 is expertly compressed by the compressor and cycled back to the condensing evaporator, maintaining a continuous and efficient cycle for superior cooling performance.
