Introducing the cutting-edge cascade refrigeration system crafted by the industry pioneers at Qingdao Bingyan Refrigeration Equipment Co., Ltd. This state-of-the-art system flawlessly transfers heat load using the dynamic duo of CO2 and NH3 refrigerants, ensuring unmatched cooling efficiency. The innovative process begins with the CO2 refrigerant absorbing heat in the end evaporator, skillfully transferred to the high-temperature NH3 refrigerant within the condensing evaporator. Subsequently, the NH3 refrigerant releases heat to the environment via the high-temperature condenser, culminating in an impeccably efficient refrigeration cycle.
The journey continues as the condensed CO2 cascades gracefully into the CO2 reservoir, navigating through the CO2 gas-liquid separator, courtesy of the dryer filter and throttle valve. Empowered by the CO2 circulation pump, the liquid CO2 journeys to the CO2 evaporator, delivering unparalleled cooling proficiency. Meanwhile, the gaseous CO2 is expertly compressed and ushered back to the condensing evaporator, perpetuating a seamless cycle of unrivaled cooling excellence.
Immerse yourself in the pinnacle of cooling efficiency and unwavering reliability with the cascade refrigeration system from Qingdao Bingyan Refrigeration Equipment Co., Ltd. Elevate your refrigeration setup to new heights today!
Advantages of NH3/CO2 Cascade Refrigeration System
Features:
- Reduced NH3 unsafe factors:
- The NH3/CO2 cascade system ingeniously diminishes NH3 condensing pressure to a mere 1/10th of traditional systems, revolutionizing safety measures and performance.
- NH3 is meticulously confined to designated zones, significantly elevating safety standards.
- The exceptional heat transfer properties of NH3 are harnessed in high-temperature regions, enhancing overall system efficacy.
- CO2 guarantees paramount safety in personnel-intensive environments and storage warehouses.
- Functioning as a low-temperature work medium, CO2 exploits its superior heat transfer efficiency, driving system performance to excellence.
