Introducing the groundbreaking cascade refrigeration system from Qingdao Bingyan Refrigeration Equipment Co., Ltd. This state-of-the-art system ingeniously manages heat transfer using CO2 and NH3 refrigerants, setting a new standard for cooling performance. The CO2 refrigerant efficiently absorbs heat in the end evaporator. This absorbed heat is masterfully transferred to the high-temperature NH3 refrigerant within the condensing evaporator. The NH3 refrigerant, now at high temperature, seamlessly releases this heat to the surrounding environment via the high-temperature condenser, thereby completing an efficient and effective refrigeration cycle.
Once condensed, the CO2 makes its way into the CO2 reservoir, before advancing through the CO2 gas-liquid separator with precision, aided by the dryer filter and throttle valve. The CO2 circulation pump plays an integral role, directing liquid CO2 towards the CO2 evaporator for unmatched cooling efficiency. The gaseous CO2, post compression by the compressor, returns to the condensing evaporator, ensuring a persistent and relentless cycle that optimizes cooling performance throughout.

Advantages of NH3/CO2 Cascade Refrigeration System
Features:
- Enhanced Safety with Reduced NH3 Risks:
- The NH3/CO2 cascade system dramatically lowers NH3 condensing pressure to just 1/10th of that in traditional systems, significantly enhancing safety.
- NH3 is strategically confined to specified areas, providing a heightened level of safety.
- Maximized heat transfer efficiency of NH3 is expertly harnessed in high-temperature zones.
- CO2 is employed in personnel-heavy spaces and storage facilities to ensure utmost safety.
- CO2 operates as a superior low-temperature medium, capitalizing on its exceptional heat transfer capabilities.
