Introducing the groundbreaking cascade refrigeration system from Qingdao Bingyan Refrigeration Equipment Co., Ltd. This state-of-the-art system masterfully manages heat load through the innovative use of CO2 and NH3 refrigerants, delivering unparalleled cooling efficiency. In this advanced process, CO2 refrigerant adeptly absorbs heat in the end evaporator, which is seamlessly transferred to the high-temperature NH3 refrigerant within the condensing evaporator. This high-temperature NH3 refrigerant then efficiently releases excess heat to the surrounding environment via the high-temperature condenser, elegantly completing the refrigeration cycle.
The system's condensed CO2 expertly flows into the CO2 reservoir, proceeding through the CO2 gas-liquid separator, facilitated by the dryer filter and throttle valve. With precision, the CO2 circulation pump directs liquid CO2 to the CO2 evaporator, ensuring efficient and powerful cooling. The gaseous CO2 is then compressively managed by the compressor and cycled back to the condensing evaporator, maintaining a smooth and continuous operation for peak cooling performance.

Advantages of the NH3/CO2 Cascade Refrigeration System
Features:
- Reducing NH3 safety risks:
- The NH3/CO2 cascade system dramatically lowers NH3 condensing pressure to just 1/10 of conventional systems.
- NH3 is strategically confined to designated zones, significantly enhancing overall safety.
- Efficient heat transfer properties of NH3 are expertly exploited in high-temperature regions.
- CO2 is utilized to ensure safety in areas with high personnel presence and warehouse environments.
- Functioning as a low-temperature work medium, CO2 capitalizes on its superior heat transfer efficiency.
