Introducing the groundbreaking cascade refrigeration system by Qingdao Bingyan Refrigeration Equipment Co., Ltd.—a marvel in modern cooling technology! This avant-garde system seamlessly orchestrates heat transfer utilizing CO2 and NH3 refrigerants, delivering extraordinary cooling efficiency. The CO2 refrigerant excels in heat absorption at the terminal evaporator, transferring it adeptly to the high-temperature NH3 refrigerant within the condensing evaporator. This high-temperature NH3 refrigerant then efficiently dissipates heat into the environment via the high-temperature condenser, completing an innovative refrigeration cycle with unmatched precision.
The journey of condensed CO2 begins as it flows into the CO2 reservoir, proceeding gracefully through the CO2 gas-liquid separator, aided by a dryer filter and throttle valve. Empowered by the CO2 circulation pump, the liquid CO2 effortlessly reaches the CO2 evaporator, optimizing cooling efficiency. Meanwhile, the gaseous CO2 is expertly compressed by the compressor and cycles back to the condensing evaporator, ensuring an uninterrupted, high-performance cooling experience.
Witness unmatched cooling efficiency and unwavering reliability with the state-of-the-art cascade refrigeration system from Qingdao Bingyan Refrigeration Equipment Co., Ltd. Elevate your refrigeration standards today!
Advantages of NH3/CO2 Cascade Refrigeration System
Features:
- Reduced NH3 unsafe factors:
- The NH3/CO2 cascade system ingeniously cuts NH3 condensing pressure to a mere 1/10 of that in traditional systems, exemplifying engineering prowess.
- NH3 is meticulously confined to designated zones, significantly enhancing safety measures.
- Efficiently leveraging NH3's superior heat transfer properties in high-temperature areas.
- CO2 is employed to guarantee safety in environments bustling with personnel and within warehouses.
- CO2 acts as a superbly efficient low-temperature working medium, capitalizing on its exceptional heat transfer capabilities.
