Introducing the pioneering cascade refrigeration system brought to you by Qingdao Bingyan Refrigeration Equipment Co., Ltd. This state-of-the-art technology seamlessly transfers heat load using the dynamic duo of CO2 and NH3 refrigerants, delivering unparalleled cooling performance. In this system, the CO2 refrigerant efficiently absorbs heat in the end evaporator, which is then adeptly transferred to the high-temperature NH3 refrigerant in the condensing evaporator. The NH3 refrigerant, now at high temperature, elegantly releases heat into the environment through the high-temperature condenser, thus flawlessly completing the refrigeration cycle.
The liquefied CO2 gracefully moves into the CO2 reservoir before making its way through the CO2 gas-liquid separator, aided by the dryer filter and throttle valve. With the precision of the CO2 circulation pump, the liquid CO2 is expertly directed to the CO2 evaporator, ensuring top-notch cooling efficiency. Meanwhile, the gaseous CO2 is expertly compressed by the compressor and returned to the condensing evaporator, perpetuating a seamless cycle for outstanding cooling performance.
Discover the epitome of cooling efficiency and 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:
- Reduced NH3 unsafe factors:
- The NH3/CO2 cascade system ingeniously reduces NH3 condensing pressure to a mere 1/10th compared to conventional systems, significantly enhancing safety.
- NH3 is strategically confined to designated areas, further bolstering safety measures.
- Capitalize on the efficient heat transfer properties of NH3, which are optimally utilized in high-temperature regions.
- CO2 serves as the guardian of safety in personnel-intensive areas and warehouses, ensuring a safe operation environment.
- CO2 functions as a powerful low-temperature work medium, leveraging its exceptional heat transfer efficiency for superior performance.
