Introducing the groundbreaking cascade refrigeration system from Qingdao Bingyan Refrigeration Equipment Co., Ltd. This state-of-the-art solution offers unparalleled efficiency by masterfully transferring heat loads using the powerful combination of CO2 and NH3 refrigerants. In this innovative process, the CO2 refrigerant initially absorbs heat in the end evaporator, subsequently transferring this thermal energy to the high-temperature NH3 refrigerant within the condensing evaporator. Ultimately, the NH3 refrigerant releases excess heat to the environment via the high-temperature condenser, thereby flawlessly completing the refrigeration cycle.
The condensed CO2 is expertly directed into the CO2 reservoir, then skillfully guided through the CO2 gas-liquid separator, passing seamlessly via the dryer filter and throttle valve. Utilizing the precision of the CO2 circulation pump, the liquid CO2 is directed towards the CO2 evaporator for exceptionally efficient cooling. The gaseous CO2 undergoes compression by the robust compressor and is returned to the condensing evaporator, maintaining a perpetual cycle for unparalleled cooling performance.
Discover unparalleled cooling efficiency and unbeatable reliability with the cascade refrigeration system from Qingdao Bingyan Refrigeration Equipment Co., Ltd. Elevate your refrigeration setup today to experience the future of cooling technology!
Advantages of NH3/CO2 Cascade Refrigeration System
Features:
- Significantly Reduced NH3 Risk Factors:
- The NH3/CO2 cascade system remarkably diminishes NH3 condensing pressure to just 1/10th of that in conventional systems.
- NH3 is expertly enclosed within designated areas, significantly enhancing safety measures.
- The excellent heat transfer properties of NH3 are strategically utilized in regions of high temperature, maximizing efficiency.
- CO2 is strategically employed to ensure safety in areas with high personnel density and in storage warehouses.
- CO2 functions as an exceptional low-temperature work medium, capitalizing on its superior heat transfer efficiency.
