Discover the pinnacle of refrigeration technology with Qingdao Bingyan Refrigeration Equipment Co., Ltd.'s revolutionary cascade refrigeration system. This state-of-the-art solution masterfully manages heat transfer utilizing the dynamic duo of CO2 and NH3 refrigerants, delivering unparalleled cooling efficiency. In this sophisticated process, CO2 serves as the initial heat absorber in the end evaporator, which is then seamlessly transferred to the robust NH3 refrigerant within the condensing evaporator. The high-temperature NH3 refrigerant then skillfully releases heat into the surroundings through the high-temperature condenser, completing a seamless and effective refrigeration cycle.
The journey of the condensed CO2 begins as it flows into the CO2 reservoir, after which it is expertly guided through the CO2 gas-liquid separator, passing through both the dryer filter and throttle valve. Thanks to the precision of the CO2 circulation pump, liquid CO2 is efficiently routed to the CO2 evaporator, ensuring a remarkable cooling process. Meanwhile, the gaseous CO2 is compressed by the compressor and returns to the condensing evaporator, maintaining a flawless, continuous cycle that guarantees optimal cooling performance.
Embrace a new era of superior cooling efficiency and unparalleled reliability with the cascade refrigeration system from Qingdao Bingyan Refrigeration Equipment Co., Ltd. Elevate your refrigeration capabilities today and enjoy a smoother production flow!
Advantages of NH3/CO2 Cascade Refrigeration System
Features:
- Minimized NH3 risk factors:
- The NH3/CO2 cascade system dramatically reduces NH3 condensing pressure to just 1/10 of that in conventional systems, ensuring a safer and more efficient operation.
- NH3 is strategically confined to specific areas, significantly enhancing safety measures.
- Leveraging the exceptional heat transfer properties of NH3 in high-temperature environments for maximum efficiency.
- CO2 is meticulously chosen to ensure absolute safety in personnel-intensive zones and storage facilities.
- CO2 functions as a formidable low-temperature medium, capitalizing on its superior heat transfer capabilities for enhanced performance.
