Presenting the revolutionary cascade refrigeration system brought to you 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. Designed for peak cooling performance, the CO2 refrigerant efficiently absorbs heat at the end evaporator, which then seamlessly transfers to the high-temperature NH3 refrigerant within the condensing evaporator. The high-temperature NH3 refrigerant adeptly releases heat to the environment via the high-temperature condenser, flawlessly completing the refrigeration cycle.
The condensed CO2 gracefully flows into the CO2 reservoir, subsequently making its way through the CO2 gas-liquid separator with the aid of the dryer filter and throttle valve. Thanks to the CO2 circulation pump, liquid CO2 is expertly directed to the CO2 evaporator, ensuring efficient cooling. The gaseous CO2 is skillfully compressed by the compressor, returning to the condensing evaporator to maintain a perpetual cycle for unmatched cooling performance.
Unlock unparalleled cooling efficiency and unwavering reliability with the cascade refrigeration system from Qingdao Bingyan Refrigeration Equipment Co., Ltd. Elevate your refrigeration setup today and experience the future of cooling!
Advantages of NH3/CO2 Cascade Refrigeration System
Features:
- Reduced NH3 Risk Factors:
- The NH3/CO2 cascade system impressively diminishes NH3 condensing pressure to a mere 1/10 of that found in traditional systems, promoting safety and efficiency.
- NH3 is meticulously confined to designated areas, significantly enhancing safety measures throughout the system.
- Leveraging the exceptional heat transfer properties of NH3 in high-temperature regions, this system maximizes efficiency.
- CO2 ensures utmost safety in areas teeming with personnel and within warehouse environments, providing peace of mind.
- CO2 functions as an exemplary low-temperature work medium, taking full advantage of its superior heat transfer efficiency.
