Introducing the ground-breaking cascade refrigeration system from Qingdao Bingyan Refrigeration Equipment Co., Ltd., designed for outstanding efficiency in heat transfer using both CO2 and NH3 refrigerants. This state-of-the-art system is engineered to deliver unparalleled cooling performance. Within the system, CO2 refrigerant excels at absorbing heat in the end evaporator, which is subsequently transferred to the robust high-temperature NH3 refrigerant within the condensing evaporator. The high-temperature NH3 then skillfully releases this heat into the environment through the high-temperature condenser, thereby completing the efficient refrigeration cycle.
Once condensed, the CO2 refrigerant is directed into the CO2 reservoir and proceeds through the CO2 gas-liquid separator, guided by the dryer filter and throttle valve. Thanks to the CO2 circulation pump, the liquid CO2 is efficiently channeled to the CO2 evaporator for superior cooling results. The gaseous CO2 is then expertly compressed by the compressor and cycled back to the condensing evaporator, ensuring a seamless and continuous operation that maximizes cooling efficiency.

Advantages of NH3/CO2 Cascade Refrigeration System
Features:
- Enhanced Safety with Reduced NH3 Risk Factors:
- The innovative NH3/CO2 cascade system significantly reduces NH3 condensing pressure by 1/10 compared to conventional systems, greatly enhancing operational safety.
- NH3 is strategically confined to designated areas, markedly improving safety measures.
- Capitalize on the efficient heat transfer properties of NH3, optimally utilized in high-temperature zones for superior performance.
- CO2 guarantees safety in personnel-dense areas and warehouses, making it the ideal choice for such environments.
- As a low-temperature work medium, CO2 exemplifies high heat transfer efficiency, essential for effective cooling.
