Introducing the groundbreaking cascade refrigeration system by Qingdao Bingyan Refrigeration Equipment Co., Ltd. This state-of-the-art system harnesses the exceptional cooling capabilities of CO2 and NH3 refrigerants to deliver unmatched thermal management. The CO2 refrigerant effectively absorbs heat within the end evaporator, which is then seamlessly transferred to the high-temperature NH3 refrigerant in the condensing evaporator. Subsequently, the high-temperature NH3 refrigerant efficiently dissipates heat into the surrounding environment via the high-temperature condenser, completing this innovative refrigeration cycle with precision.
The condensed CO2 seamlessly flows into the CO2 reservoir and navigates through the CO2 gas-liquid separator, guided by the dryer filter and throttle valve. Facilitated by the CO2 circulation pump, the liquid CO2 is expertly channeled to the CO2 evaporator for superior cooling. Meanwhile, the gaseous CO2 is expertly compressed by the compressor and recycled back to the condensing evaporator, ensuring a continuous, efficient cycle that guarantees optimal cooling performance.

Advantages of NH3/CO2 Cascade Refrigeration System
Features:
- Significantly Reduced NH3 Hazards:
- The NH3/CO2 cascade system dramatically lowers NH3 condensing pressure to just 1/10 of that in traditional systems, enhancing safety and efficiency.
- NH3 is meticulously confined to specified areas, further boosting safety measures.
- The exceptional heat transfer properties of NH3 are effectively utilized in high-temperature zones, ensuring robust performance.
- CO2 provides a secure solution in areas populated with personnel and in warehouse environments, prioritizing safety.
- CO2 serves as a premier low-temperature working medium, leveraging its outstanding heat transfer efficiency to maximum advantage.
