Introducing the groundbreaking cascade refrigeration system by Qingdao Bingyan Refrigeration Equipment Co., Ltd. Harnessing the synergy of CO2 and NH3 refrigerants, this system sets a new benchmark in cooling efficiency. With CO2 serving as the primary heat absorber within the end evaporator, it seamlessly transfers this heat to the more robust NH3 refrigerant in the condensing evaporator. The NH3 refrigerant, in turn, dissipates the absorbed heat into the environment using a state-of-the-art high-temperature condenser, culminating the refrigeration cycle with unmatched performance.
The journey of cooling excellence continues as the condensed CO2 streams into the CO2 reservoir, moving through an advanced CO2 gas-liquid separator and precision-engineered dryer filter and throttle valve. Powered by the CO2 circulation pump, liquid CO2 is optimally directed towards the CO2 evaporator for superior cooling. The gaseous CO2 is skillfully compressed and channeled back to the condensing evaporator, ensuring an uninterrupted cycle of exceptional cooling efficiency.
