Introducing the groundbreaking cascade refrigeration system crafted by Qingdao Bingyan Refrigeration Equipment Co., Ltd. This state-of-the-art system masterfully transfers heat load using the potent combination of CO2 and NH3 refrigerants, guaranteeing exceptional cooling performance. Within this advanced system, 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. The NH3 refrigerant, now at high temperature, skillfully releases heat to the environment through the high-temperature condenser, flawlessly completing the refrigeration cycle.
In this meticulous process, the condensed CO2 flows with precision into the CO2 reservoir, then navigates through the CO2 gas-liquid separator via a dryer filter and throttle valve. Empowered by the CO2 circulation pump, the liquid CO2 is expertly directed to the CO2 evaporator, delivering efficient and effective cooling. The gaseous form of CO2 is then compressed by the system's robust compressor and elegantly returned to the condensing evaporator, ensuring an uninterrupted cycle that consistently provides optimal cooling performance.

Advantages of NH3/CO2 Cascade Refrigeration System
Features:
- Reduced NH3 unsafe factors:
- The NH3/CO2 cascade system innovatively reduces NH3 condensing pressure by 1/10 compared to traditional systems, enhancing safety and efficiency.
- NH3 is strategically confined to designated areas, significantly enhancing safety protocols.
- The system harnesses the efficient heat transfer properties of NH3 in high-temperature regions, optimizing performance.
- CO2 is employed to ensure safety in personnel-intensive areas and warehouses, maintaining a secure environment.
- CO2 operates as a low-temperature work medium, capitalizing on its superior heat transfer efficiency to boost performance.
