Introducing the ground-breaking cascade refrigeration system crafted by Qingdao Bingyan Refrigeration Equipment Co., Ltd. This state-of-the-art system masterfully manages heat load transfer using CO2 and NH3 refrigerants, delivering unparalleled cooling performance. In this innovative process, the CO2 refrigerant adeptly absorbs heat in the end evaporator. This absorbed heat is then seamlessly transferred to the high-temperature NH3 refrigerant within the condensing evaporator. Subsequently, the high-temperature NH3 refrigerant efficiently dissipates heat to the surroundings via the high-temperature condenser, thus completing the sophisticated refrigeration cycle.
The condensed CO2 gracefully flows into the CO2 reservoir, progressing through the CO2 gas-liquid separator with the aid of a dryer filter and throttle valve. Facilitated by the CO2 circulation pump, the liquid CO2 is precisely directed to the CO2 evaporator, ensuring superior cooling efficacy. Meanwhile, the gaseous CO2 is expertly compressed by the compressor and returns to the condensing evaporator, maintaining an uninterrupted 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 an impressive 1/10 compared to conventional systems.
- NH3 is meticulously confined to specific designated areas, significantly enhancing the safety of the system.
- Leveraging the efficient heat transfer properties of NH3, it is effectively utilized in high-temperature regions.
- CO2 ensures exceptional safety in personnel-intensive areas and warehouses, making it a reliable choice.
- Functioning as a low-temperature work medium, CO2 capitalizes on its remarkable heat transfer efficiency for optimal performance.
