Introducing the groundbreaking cascade refrigeration system by Qingdao Bingyan Refrigeration Equipment Co., Ltd. This state-of-the-art system excels in transferring heat load by harnessing the power of CO2 and NH3 refrigerants, guaranteeing superior cooling performance. The CO2 refrigerant efficiently absorbs heat in the terminal evaporator, which is seamlessly transferred to the high-temperature NH3 refrigerant in the condensing evaporator. The NH3 refrigerant at high temperature effectively dissipates heat to the environment via the high-temperature condenser, completing the refrigeration cycle with unmatched efficiency.
The condensed CO2 seamlessly flows into the CO2 reservoir, then navigates through the CO2 gas-liquid separator with the assistance of the dryer filter and throttle valve. Leveraging the CO2 circulation pump, the liquid CO2 is skillfully directed to the CO2 evaporator for exceptional cooling. The gaseous CO2 is expertly compressed by the compressor and redirected to the condensing evaporator, ensuring an uninterrupted cycle that delivers peak cooling performance.
Unleash the power of superior cooling efficiency and unwavering reliability with 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:
- Mitigation of NH3 safety risks:
- The NH3/CO2 cascade system ingeniously reduces NH3 condensing pressure by an impressive 1/10 compared to conventional systems.
- NH3 is strategically confined to designated zones, significantly enhancing safety measures.
- The exceptional heat transfer properties of NH3 are leveraged in high-temperature regions.
- CO2 ensures unparalleled safety in personnel-intensive areas and warehouses.
- CO2 operates as a low-temperature work medium, capitalizing on its superior heat transfer efficiency.
