Product Description
Discover the groundbreaking cascade refrigeration system by Qingdao Bingyan Refrigeration Equipment Co., Ltd. Our state-of-the-art system masterfully transfers heat load using CO2 and NH3 refrigerants, achieving unmatched cooling performance. With CO2 refrigerant absorbing heat in the end evaporator, the heat is then efficiently channeled to the high-temperature NH3 refrigerant within the condensing evaporator. The high-temperature NH3 refrigerant efficiently dissipates heat into the environment via the high-temperature condenser, completing this sophisticated refrigeration cycle.
The condensed CO2 elegantly flows into the CO2 reservoir, then seamlessly transitions through the CO2 gas-liquid separator via the dryer filter and throttle valve. With the assistance of the CO2 circulation pump, liquid CO2 is expertly directed to the CO2 evaporator for pinnacle cooling efficiency. The gaseous CO2 is adeptly compressed by the compressor and returned to the condensing evaporator, securing a continuous cycle for peak cooling performance.

CO2 Gas-Liquid Separator by Qingdao Bingyan Refrigeration Equipment Co., Ltd.
The CO2 gas-liquid separator is crucial for efficiently separating CO2 gas droplets in a sophisticated compression refrigeration system. It expertly prevents compressor wet stroke, maintains stable liquid levels during pump operation, and ensures safe liquid storage when the pump is inactive. Additionally, it doubles as a reservoir for CO2, maximizing system efficiency. An auxiliary evaporator prevents excessive CO2 pressure post-shutdown, safeguarding the system.
In our NH3/CO2 cascade systems, the condensing evaporator ingeniously functions as both the NH3 evaporator and CO2 condenser. This unique design significantly optimizes heat absorption and liquid condensation, delivering superior refrigeration performance.

Discover the unparalleled Advantages of the NH3/CO2 Cascade Refrigeration System, a groundbreaking solution that redefines efficiency and safety in modern refrigeration technology.
Features:
- Minimized NH3 Risk Factors:
- Revolutionizing safety and efficiency, the NH3/CO2 cascade system significantly lowers NH3 condensing pressure to just one-tenth of traditional systems, setting a new standard for refrigeration reliability.
- With NH3 safely confined to designated areas, this system dramatically enhances safety protocols and reduces exposure risks.
- Experience unparalleled heat transfer efficiency with NH3's superior thermal properties, expertly harnessed in high-temperature regions for maximum performance.
- Prioritizing safety in personnel-dense environments, CO2 ensures a secure atmosphere in warehouses and other crucial areas.
- Leveraging CO2's exceptional heat transfer capabilities, this system excels as a low-temperature work medium, optimizing overall refrigeration efficiency.
