Introducing the groundbreaking cascade refrigeration system brought to you by Qingdao Bingyan Refrigeration Equipment Co., Ltd. This state-of-the-art system is engineered to efficiently manage heat transfers by employing the innovative combination of CO2 and NH3 refrigerants, ensuring exceptional cooling performance. Within this advanced system, the CO2 refrigerant adeptly absorbs heat within the end evaporator, which is subsequently transferred to the high-temperature NH3 refrigerant in the condensing evaporator. The high-temperature NH3 then disperses the absorbed heat into the environment via the high-temperature condenser, thus completing this sophisticated refrigeration cycle.
The process continues as the condensed CO2 flows seamlessly into the CO2 reservoir, proceeding through the CO2 gas-liquid separator via the dryer filter and throttle valve. With the assistance of the highly efficient CO2 circulation pump, liquid CO2 is skillfully directed to the CO2 evaporator, ensuring unparalleled cooling efficiency. The gaseous CO2 is expertly compressed by the compressor and reintroduced into the condensing evaporator, guaranteeing a consistent cycle for optimal cooling performance.
Unleash exceptional cooling efficiency and steadfast reliability with the cutting-edge cascade refrigeration system from Qingdao Bingyan Refrigeration Equipment Co., Ltd. Elevate your refrigeration capabilities and upgrade your system today!
Advantages of the NH3/CO2 Cascade Refrigeration System
