Introducing the groundbreaking cascade refrigeration system by Qingdao Bingyan Refrigeration Equipment Co., Ltd. Embrace the future of cooling with this state-of-the-art system, which masterfully handles heat loads through the harmonious use of CO2 and NH3 refrigerants. The CO2 refrigerant ingeniously captures heat in the end evaporator, which is then expertly transferred to the high-temperature NH3 refrigerant in the condensing evaporator. This NH3 refrigerant skillfully dispels heat to the environment via the high-temperature condenser, thus completing the refrigeration cycle with unmatched efficiency.
The condensed CO2 seamlessly flows into the CO2 reservoir, subsequently moving through the CO2 gas-liquid separator with the assistance of the dryer filter and throttle valve. Empowered by the CO2 circulation pump, the liquid CO2 is delivered to the CO2 evaporator, achieving remarkable cooling. The CO2 gas is then compressed by the compressor and returned to the condensing evaporator, ensuring an uninterrupted cycle for superior cooling performance.
