Introducing a revolutionary innovation in cooling technology by Qingdao Bingyan Refrigeration Equipment Co., Ltd. Presenting our state-of-the-art cascade refrigeration system, which showcases remarkable efficiency and precision. This advanced system employs the superior properties of both CO2 and NH3 refrigerants, guaranteeing exceptional cooling performance. In this dynamic process, the CO2 refrigerant adeptly absorbs heat within the end evaporator, transferring it seamlessly to the high-temperature NH3 refrigerant housed within the condensing evaporator. The NH3 refrigerant then efficiently releases heat to the environment via the high-temperature condenser, completing a flawless refrigeration cycle.
The ingeniously condensed CO2 makes its way into the CO2 reservoir before journeying through the CO2 gas-liquid separator, skillfully passing through the dryer filter and throttle valve. By harnessing the power of the CO2 circulation pump, liquid CO2 is directed purposefully towards the CO2 evaporator, where it achieves remarkable cooling efficiency. Meanwhile, the gaseous CO2 is expertly compressed by the compressor, reintroduced to the condensing evaporator to ensure an uninterrupted cycle, maximizing cooling performance.

Advantages of NH3/CO2 Cascade Refrigeration System
Features:
- Minimized NH3 risk factors:
- The NH3/CO2 cascade system innovatively reduces NH3 condensing pressure by a significant 1/10 compared to traditional systems, promising enhanced safety and efficiency.
- NH3 is meticulously contained within designated areas, substantially boosting safety measures.
- The efficient heat transfer properties of NH3 are strategically used in high-temperature regions, optimizing the system's performance.
- CO2 offers heightened safety in areas with dense personnel and expansive warehouses.
- Functioning as a low-temperature work medium, CO2 takes full advantage of its excellent heat transfer efficiency.
