Introducing the innovative cascade refrigeration system by Qingdao Bingyan Refrigeration Equipment Co., Ltd. Experience unparalleled efficiency with this state-of-the-art system that masterfully transfers heat load using CO2 and NH3 refrigerants, delivering peak cooling performance. Our CO2 refrigerant adeptly absorbs heat in the end evaporator, which is then seamlessly transferred to the high-temperature NH3 refrigerant in the condensing evaporator. In an elegant conclusion to the cycle, the high-temperature NH3 refrigerant releases its heat to the environment through the high-temperature condenser.
The condensed CO2 flows into the CO2 reservoir and advances through the CO2 gas-liquid separator via the dryer filter and throttle valve. With precision and power, the CO2 circulation pump directs the liquid CO2 to the CO2 evaporator, achieving efficient cooling. The gaseous CO2, with vigor, is compressed by the compressor and makes its way back to the condensing evaporator, ensuring a seamless, continuous cycle that guarantees optimal cooling performance.
Experience unmatched cooling efficiency and reliability with the cascade refrigeration system crafted by Qingdao Bingyan Refrigeration Equipment Co., Ltd. Elevate your refrigeration setup to new heights today!
Advantages of NH3/CO2 Cascade Refrigeration System
Features:
- Reduced NH3 unsafe factors:
- The NH3/CO2 cascade system ingeniously reduces NH3 condensing pressure by a substantial 1/10 compared to traditional systems.
- NH3 is meticulously confined to designated areas, significantly enhancing safety.
- The efficient heat transfer properties of NH3 are masterfully utilized in high-temperature regions, maximizing effectiveness.
- CO2 ensures an unwavering level of safety in personnel-intensive areas and warehouses, safeguarding your environment.
- CO2 serves as a low-temperature work medium, exploiting its extraordinarily high heat transfer efficiency to full effect.
