Introducing the innovative cascade refrigeration system engineered by Qingdao Bingyan Refrigeration Equipment Co., Ltd. This state-of-the-art system masterfully handles the heat transfer process by employing the synergistic properties of CO2 and NH3 refrigerants. Designed for excellence, it ensures unparalleled cooling performance. In this advanced system, the CO2 refrigerant takes on the critical role of absorbing heat in the end evaporator. This absorbed thermal energy is then intelligently transferred to the high-temperature NH3 refrigerant within the condensing evaporator. The NH3 refrigerant, now carrying the heat, efficiently releases it to the environment through the high-temperature condenser, thereby completing a seamless and efficient refrigeration cycle.
Within this sophisticated system, the condensed CO2 makes its way into the CO2 reservoir and then advances through the CO2 gas-liquid separator, with the aid of the dryer filter and throttle valve. Propelled by the CO2 circulation pump, the liquid CO2 is skillfully directed towards the CO2 evaporator, ensuring highly efficient cooling. Meanwhile, the gaseous CO2 undergoes compression by the compressor and is then returned to the condensing evaporator. This ensures a consistent and continuous cycle, ultimately delivering optimal cooling performance at all times.
Experience the pinnacle of cooling efficiency and unwavering reliability with the cutting-edge cascade refrigeration system from Qingdao Bingyan Refrigeration Equipment Co., Ltd. Elevate your refrigeration system to new heights today and enjoy unmatched performance!
Advantages of NH3/CO2 Cascade Refrigeration System
Features:
- Reduced NH3 unsafe factors:
- The NH3/CO2 cascade system ingeniously reduces NH3 condensing pressure by 1/10 compared to traditional systems, significantly enhancing safety and efficiency.
- NH3 is strategically confined to specific areas, greatly augmenting safety measures and minimizing risk.
- The exceptional heat transfer properties of NH3 are expertly utilized in high-temperature regions, maximizing efficiency.
- CO2 plays a crucial role in ensuring safety in personnel-intensive areas and warehouses, offering peace of mind.
- CO2 serves as a powerful low-temperature work medium, exploiting its outstanding high heat transfer efficiency to full advantage.
