Introducing the revolutionary cascade refrigeration system developed by Qingdao Bingyan Refrigeration Equipment Co., Ltd. This state-of-the-art system is meticulously designed to efficiently handle heat loads by leveraging the exceptional capabilities of CO2 and NH3 refrigerants. In this innovative process, CO2 refrigerant operates by absorbing heat within the end evaporator, seamlessly transferring this heat to the high-temperature NH3 refrigerant within the condensing evaporator. The NH3 refrigerant, at a high temperature, then effectively dissipates heat into the surrounding environment through the high-temperature condenser, thus completing the sophisticated refrigeration cycle and ensuring unrivaled cooling performance.
The journey of condensed CO2 begins as it flows effortlessly into the CO2 reservoir, subsequently navigating through the CO2 gas-liquid separator via the precision-engineered dryer filter and throttle valve. Empowered by the advanced CO2 circulation pump, the liquid CO2 is adeptly directed to the CO2 evaporator, where it delivers top-notch cooling efficiency. Meanwhile, the gaseous CO2 is expertly compressed by the state-of-the-art compressor and returned to the condensing evaporator, maintaining an uninterrupted cycle that guarantees optimal cooling performance at all times.
Discover the unmatched cooling efficiency and steadfast reliability offered by the cascade refrigeration system from Qingdao Bingyan Refrigeration Equipment Co., Ltd. Elevate your refrigeration setup today and experience the pinnacle of modern cooling technology!
Advantages of the NH3/CO2 Cascade Refrigeration System
Features:
- Enhanced Safety with Reduced NH3 Risks:
- The NH3/CO2 cascade system ingeniously reduces NH3 condensing pressure by an impressive 1/10 when compared to traditional refrigeration systems.
- NH3 is strategically confined to designated zones, significantly enhancing safety standards.
- The system capitalizes on the exceptional heat transfer properties of NH3 in high-temperature areas to maximize efficiency.
- The use of CO2 enhances safety in areas with high personnel density and in extensive warehouse spaces.
- As a low-temperature work medium, CO2 excels with its superior heat transfer efficiency, making it an ideal choice for modern refrigeration.
Take advantage of the groundbreaking NH3/CO2 cascade refrigeration system brought to you by Qingdao Bingyan Refrigeration Equipment Co., Ltd., and step into a new era of cooling technology.
