Introducing the groundbreaking cascade refrigeration system, proudly offered by Qingdao Bingyan Refrigeration Equipment Co., Ltd. This state-of-the-art system excels in efficiently managing heat transfer by utilizing advanced CO2 and NH3 refrigerants. Designed for superior cooling performance, the system operates smoothly as the CO2 refrigerant absorbs heat in the end evaporator, which is then efficiently transferred to the high-temperature NH3 refrigerant within the condensing evaporator. This process reaches completion when the high-temperature NH3 refrigerant effectively releases heat into the environment through the high-temperature condenser, thereby concluding the refrigeration cycle with unparalleled precision.
The condensed CO2 seamlessly moves into the CO2 reservoir and is expertly guided through the CO2 gas-liquid separator, passing meticulously via the dryer filter and throttle valve. The CO2 circulation pump then takes charge, directing the liquid CO2 to the CO2 evaporator, ensuring unparalleled cooling efficiency. Meanwhile, the gaseous CO2 is expertly compressed by the high-performance compressor and returned to the condensing evaporator, maintaining an uninterrupted cycle that guarantees optimal cooling performance at all times.

Advantages of the NH3/CO2 Cascade Refrigeration System
Features:
- Reduced NH3 Safety Concerns:
- The NH3/CO2 cascade system ingeniously minimizes NH3 condensing pressure by an impressive 1/10th when compared to conventional systems.
- NH3 is strategically confined to specific designated areas, significantly enhancing overall safety parameters.
- Tapping into the efficient heat transfer properties of NH3, the system leverages these characteristics particularly in high-temperature operational regions.
- CO2 plays a vital role in ensuring safety within personnel-intensive spaces and storage warehouses.
- Functioning as a low-temperature work medium, CO2 is adept at capitalizing on its exceptionally high heat transfer efficiency.
