Introducing the revolutionary cascade refrigeration system from Qingdao Bingyan Refrigeration Equipment Co., Ltd. This state-of-the-art technology offers unparalleled heat transfer capabilities using the perfect synergy of CO2 and NH3 refrigerants, delivering exceptional cooling performance. The CO2 refrigerant adeptly absorbs heat in the end evaporator, seamlessly transferring it to the high-temperature NH3 refrigerant within the condensing evaporator. The NH3 refrigerant, operating at a higher temperature, then efficiently discharges the heat into the environment via the high-temperature condenser, successfully completing the refrigeration cycle.
The condensed CO2 makes its way into the CO2 reservoir and proceeds through the CO2 gas-liquid separator, guided by the dryer filter and throttle valve. Driven by the CO2 circulation pump, the liquid CO2 is smoothly channeled to the CO2 evaporator, ensuring optimal cooling efficiency. Meanwhile, the gaseous CO2 is expertly compressed by the compressor and routed back to the condensing evaporator, maintaining a seamless and continuous cycle that guarantees superior cooling performance.

Advantages of NH3/CO2 Cascade Refrigeration System
Features:
- Minimized NH3 Risk Factors:
- The NH3/CO2 cascade system significantly reduces NH3 condensing pressure to just 1/10th of that in conventional systems.
- NH3 is strategically confined to specific zones, elevating safety levels.
- The remarkable heat transfer properties of NH3 are expertly harnessed in high-temperature sectors.
- CO2 ensures optimal safety in areas with high personnel density and warehouse environments.
- CO2 excels as a low-temperature working medium, capitalizing on its superior heat transfer efficiency.
