Presenting the groundbreaking cascade refrigeration system created by Qingdao Bingyan Refrigeration Equipment Co., Ltd. This state-of-the-art system innovatively manages heat transfer using the power of CO2 and NH3 refrigerants, achieving unparalleled cooling efficiency. The CO2 refrigerant efficiently absorbs heat within the end evaporator, transferring this heat seamlessly to the high-temperature NH3 refrigerant within the condensing evaporator. The NH3 refrigerant then effectively releases this heat to the environment through the high-temperature condenser, completing a highly efficient refrigeration cycle.
The condensed CO2 is expertly channeled into the CO2 reservoir, then navigates through the CO2 gas-liquid separator aided by the dryer filter and throttle valve. With precision, the CO2 circulation pump directs the liquid CO2 to the CO2 evaporator, ensuring highly efficient cooling. The gaseous CO2 is expertly compressed by the reliable compressor and returned to the condensing evaporator, facilitating a continuous cycle that guarantees optimal cooling performance.

Advantages of NH3/CO2 Cascade Refrigeration System
Features:
- Reduced NH3 unsafe factors:
- The NH3/CO2 cascade system ingeniously reduces NH3 condensing pressure by a remarkable 1/10 compared to conventional systems.
- NH3 is strategically confined to specific designated areas, significantly enhancing safety measures.
- Utilizing the efficient heat transfer properties of NH3 in high-temperature regions enhances operational efficiency.
- CO2 ensures optimal safety in personnel-intensive areas and expansive warehouses.
- CO2 serves as an exceptional low-temperature work medium, capitalizing on its high heat transfer efficiency.
