Introducing the revolutionary cascade refrigeration system by Qingdao Bingyan Refrigeration Equipment Co., Ltd. This state-of-the-art refrigeration marvel seamlessly integrates CO2 and NH3 refrigerants to achieve unparalleled cooling efficiency. The CO2 refrigerant excels at absorbing heat within the end evaporator, which is then masterfully transferred to the high-temperature NH3 refrigerant within the condensing evaporator. The NH3 refrigerant skillfully releases this heat to the surrounding environment through the high-temperature condenser, thus completing a flawless refrigeration cycle that promises exceptional performance.
The condensed CO2 gracefully flows into the CO2 reservoir, embarking on a journey through the CO2 gas-liquid separator, facilitated by the dryer filter and throttle valve. Powered by the CO2 circulation pump, the liquid CO2 is expertly directed to the CO2 evaporator to deliver efficient and refreshing cooling. Meanwhile, the gaseous CO2 is compressed by the compressor and returned to the condensing evaporator, ensuring a seamless and continuous cooling cycle that maximizes performance excellence.
Embrace the future of cooling with unparalleled efficiency and reliability, thanks to the cascade refrigeration system from Qingdao Bingyan Refrigeration Equipment Co., Ltd. Elevate your refrigeration setup to new heights today!
Advantages of NH3/CO2 Cascade Refrigeration System
Features:
- Reduced NH3 Safety Concerns:
- The NH3/CO2 cascade system ingeniously reduces NH3 condensing pressure to just 1/10 of traditional systems, enhancing safety and performance.
- NH3 is meticulously confined to designated areas, significantly enhancing overall safety protocols.
- Efficient heat transfer properties of NH3 are expertly harnessed in high-temperature regions, ensuring optimal performance.
- CO2 guarantees unparalleled safety in personnel-intensive areas and busy warehouses, safeguarding all operations.
- CO2 serves as a superior low-temperature work medium, capitalizing on its outstanding heat transfer efficiency.
