Introducing the revolutionary cascade refrigeration system by Qingdao Bingyan Refrigeration Equipment Co., Ltd. This state-of-the-art system masterfully transfers heat load by deploying the dual power of CO2 and NH3 refrigerants. Experience unmatched cooling performance as the CO2 refrigerant adeptly absorbs heat in the end evaporator. This absorbed heat is then efficiently transferred to the high-temperature NH3 refrigerant within the condensing evaporator. Once here, the high-temperature NH3 refrigerant skillfully releases the absorbed heat into the environment through the high-temperature condenser, flawlessly completing the refrigeration cycle.
The condensed CO2 seamlessly flows into the CO2 reservoir, then elegantly navigates through the CO2 gas-liquid separator via the meticulously engineered dryer filter and throttle valve. With the robust assistance of the CO2 circulation pump, the liquid CO2 is expertly directed to the CO2 evaporator, ensuring efficient cooling. The gaseous CO2 is dynamically compressed by the compressor and swiftly returned to the condensing evaporator, enabling a continuous and optimal cooling cycle.
Discover unparalleled cooling efficiency and reliability with the exceptional cascade refrigeration system from Qingdao Bingyan Refrigeration Equipment Co., Ltd. Elevate your refrigeration setup today and experience groundbreaking performance!
Advantages of NH3/CO2 Cascade Refrigeration System
Features:
- Reduced NH3 unsafe factors:
- The NH3/CO2 cascade system ingeniously reduces NH3 condensing pressure by an impressive 1/10 compared to traditional systems, significantly enhancing safety.
- NH3 is strategically confined to designated areas, further enhancing operational safety.
- The system leverages the efficient heat transfer properties of NH3, especially in high-temperature regions, to maximize performance.
- CO2 is utilized to ensure safety in personnel-intensive areas and warehouses, offering peace of mind.
- CO2 operates as a low-temperature work medium, capitalizing on its remarkable high heat transfer efficiency.
