Introducing the state-of-the-art cascade refrigeration system by Qingdao Bingyan Refrigeration Equipment Co., Ltd. This revolutionary system brilliantly harnesses the power of CO2 and NH3 refrigerants to expertly manage heat loads, delivering unmatched cooling performance. In this ingenious process, the CO2 refrigerant captures heat at the end evaporator, which is seamlessly transferred to the high-temperature NH3 refrigerant within the condensing evaporator. Subsequently, the high-temperature NH3 refrigerant effortlessly dissipates heat to the surrounding environment via the high-temperature condenser, thus completing a flawless refrigeration cycle.
The condensed CO2 is expertly guided into the CO2 reservoir, followed by a journey through the CO2 gas-liquid separator, dryer filter, and throttle valve. Thanks to the precision of the CO2 circulation pump, the liquid CO2 is channeled into the CO2 evaporator, where it achieves exceptional cooling efficiency. Meanwhile, the gaseous CO2 is skillfully compressed by the compressor and returned to the condensing evaporator, ensuring an endless cycle of optimal cooling performance.
Elevate your cooling experience with the unparalleled efficiency and reliability of the cascade refrigeration system from Qingdao Bingyan Refrigeration Equipment Co., Ltd. Transform your refrigeration setup today and witness the future of cooling technology!
Advantages of the NH3/CO2 Cascade Refrigeration System
Features:
- Enhanced Safety with Reduced NH3 Factors:
- The NH3/CO2 cascade system impressively reduces NH3 condensing pressure by a remarkable 1/10 compared to conventional systems.
- NH3 is strategically confined to designated areas, significantly enhancing safety measures.
- The system leverages the efficient heat transfer properties of NH3 in high-temperature zones.
- CO2 ensures optimal safety in personnel-intensive areas and storage warehouses.
- CO2 serves as a low-temperature work medium, capitalizing on its superior heat transfer efficiency.
