Step into the future of refrigeration with the revolutionary cascade refrigeration system brought to you by Qingdao Bingyan Refrigeration Equipment Co., Ltd. This state-of-the-art system masterfully manages heat load with the synergistic use of CO2 and NH3 refrigerants. At the heart of this impressive technology, CO2 takes the lead by soaking up heat at the end evaporator. Next, this heat seamlessly transfers to the high-temperature NH3 refrigerant within the condensing evaporator. Finally, the NH3 refrigerant, now heated, gracefully dispels its warmth into the environment through the high-temperature condenser, thus concluding a highly efficient refrigeration cycle.
The journey of the condensed CO2 begins as it smoothly flows into the CO2 reservoir. From there, it elegantly passes through the CO2 gas-liquid separator, aided by the dryer filter and throttle valve. The CO2 circulation pump propels the liquid CO2 towards the CO2 evaporator for superior cooling efficacy. Meanwhile, the gaseous CO2 is expertly compressed by the compressor and then returned to the condensing evaporator, ensuring a seamless, uninterrupted cycle that guarantees top-tier cooling performance.
Unleash unparalleled cooling efficiency and steadfast reliability with the cascade refrigeration system exclusively from Qingdao Bingyan Refrigeration Equipment Co., Ltd. Elevate your refrigeration systems to new heights today!
Advantages of the NH3/CO2 Cascade Refrigeration System
Outstanding Features:
- Significant Reduction in NH3 Risks:
- The NH3/CO2 cascade system remarkably lowers NH3 condensing pressure to a mere 1/10 of that in traditional systems, enhancing operational efficiency and safety.
- NH3 is meticulously confined to specific areas, thereby greatly enhancing safety and reducing risks.
- The intrinsic heat transfer properties of NH3 are expertly harnessed in high-temperature zones, optimizing performance.
- CO2 ensures a safety-first environment, particularly in personnel-dense areas and storage warehouses, prioritizing human welfare.
- CO2 acts as a superior low-temperature work medium, leveraging its exceptional heat transfer efficiency for optimal results.
