Unveiling the state-of-the-art cascade refrigeration system by Qingdao Bingyan Refrigeration Equipment Co., Ltd. This revolutionary system masterfully handles heat transfer with the use of advanced CO2 and NH3 refrigerants, delivering superior cooling performance. The CO2 refrigerant adeptly absorbs heat in the end evaporator, which is seamlessly transferred to the high-temperature NH3 refrigerant within the condensing evaporator. Subsequently, the NH3 refrigerant efficiently discharges heat to the environment via the cutting-edge high-temperature condenser, completing a flawless refrigeration cycle.
In this sophisticated system, the condensed CO2 is expertly channeled into the CO2 reservoir, flowing onward through the CO2 gas-liquid separator, aided by the dryer filter and throttle valve. Powered by the CO2 circulation pump, the liquid CO2 is precisely guided to the CO2 evaporator for exceptional cooling, while the gaseous CO2 is effectively compressed by the advanced compressor and returned to the condensing evaporator, ensuring a seamless and continuous cycle for peak cooling performance.

Advantages of NH3/CO2 Cascade Refrigeration System
Features:
- Minimized NH3 Safety Concerns:
- The NH3/CO2 cascade system ingeniously reduces NH3 condensing pressure to just 1/10 of traditional systems.
- NH3 is strategically confined to designated areas, significantly enhancing safety.
- The exceptional heat transfer properties of NH3 are leveraged effectively in high-temperature regions.
- CO2 is employed to ensure safety in densely populated areas and storage warehouses.
- Serving as a low-temperature work medium, CO2 capitalizes on its superior heat transfer efficiency.
