Presenting the groundbreaking cascade refrigeration system by Qingdao Bingyan Refrigeration Equipment Co., Ltd., where innovation meets efficiency. This state-of-the-art system seamlessly transfers heat load with the unrivaled combination of CO2 and NH3 refrigerants, guaranteeing superior cooling performance. The CO2 refrigerant initiates the process by absorbing heat in the end evaporator. This absorbed heat is then ingeniously transferred to the high-temperature NH3 refrigerant within the condensing evaporator. The cycle culminates as the high-temperature NH3 refrigerant efficiently releases heat to the environment through the high-temperature condenser, completing a flawless refrigeration cycle.
Embark on a cooling journey where condensed CO2 flows into the reservoir, navigating through the CO2 gas-liquid separator via the advanced dryer filter and throttle valve. With the expertise of the CO2 circulation pump, liquid CO2 is meticulously directed to the CO2 evaporator, ensuring impeccable cooling standards. Simultaneously, gaseous CO2 is masterfully compressed by the compressor and returned to the condensing evaporator, fostering an uninterrupted cycle crafted for peak cooling excellence.
