Introducing the pioneering cascade refrigeration system from Qingdao Bingyan Refrigeration Equipment Co., Ltd. This state-of-the-art system adeptly transfers heat utilizing CO2 and NH3 refrigerants, guaranteeing unmatched cooling performance. The CO2 refrigerant efficiently absorbs heat in the end evaporator, transferring it seamlessly to the high-temperature NH3 refrigerant within the condensing evaporator. The high-temperature NH3 refrigerant skillfully releases heat to the environment via the high-temperature condenser, completing the refrigeration cycle with precision.
The condensed CO2 gracefully flows into the CO2 reservoir and then navigates through the CO2 gas-liquid separator, guided by the dryer filter and throttle valve. Driven by the CO2 circulation pump, the liquid CO2 is expertly directed to the CO2 evaporator, ensuring efficient cooling. The gaseous CO2 is compressed by the compressor and smoothly returns to the condensing evaporator, maintaining a continuous cycle that ensures peak cooling performance.
Elevate your cooling experience with the superior efficiency and reliability of the cascade refrigeration system from Qingdao Bingyan Refrigeration Equipment Co., Ltd. Transform your refrigeration setup today and witness the difference!
Advantages of NH3/CO2 Cascade Refrigeration System
Features:
- Enhanced Safety with Reduced NH3 Risks:
