Introducing the revolutionary cascade refrigeration system from the esteemed Qingdao Bingyan Refrigeration Equipment Co., Ltd. This state-of-the-art system triumphantly handles heat load transfer by utilizing CO2 and NH3 refrigerants, delivering unmatched cooling performance. In this ingenious process, the CO2 refrigerant absorbs heat in the end evaporator and seamlessly transfers it to the high-temperature NH3 refrigerant within the condensing evaporator. The high-temperature NH3 refrigerant then elegantly dissipates heat to the environment through the high-temperature condenser, thus completing an effective refrigeration cycle.
The condensed CO2 gracefully flows into the CO2 reservoir, subsequently making its way through the CO2 gas-liquid separator via the dryer filter and throttle valve. With the powerful assistance of the CO2 circulation pump, the liquid CO2 is efficiently channeled to the CO2 evaporator for supreme cooling. The gaseous CO2 is adeptly compressed by the compressor and skillfully returned to the condensing evaporator, ensuring a perpetual cycle of optimal cooling performance.
Discover unparalleled cooling efficiency and unwavering reliability with the cascade refrigeration system from Qingdao Bingyan Refrigeration Equipment Co., Ltd. Transform your refrigeration setup today to experience cutting-edge innovation!
Advantages of NH3/CO2 Cascade Refrigeration System
Features:
- Enhanced safety with reduced NH3 unsafe factors:
- The NH3/CO2 cascade system significantly reduces NH3 condensing pressure to a mere 1/10 of traditional systems.
- NH3 is strategically confined to designated areas, greatly elevating safety standards.
- The system capitalizes on the exceptional heat transfer properties of NH3 in high-temperature regions.
- CO2 promotes safety in personnel-intensive zones and warehouses, ensuring peace of mind.
- CO2 serves as a low-temperature work medium, harnessing its superior heat transfer efficiency.
