Introducing the state-of-the-art cascade refrigeration system from the renowned Qingdao Bingyan Refrigeration Equipment Co., Ltd. This pioneering technology is expertly designed to transfer heat load with remarkable efficiency, utilizing the powerful combination of CO2 and NH3 refrigerants for unrivaled cooling performance. The CO2 refrigerant ingeniously absorbs heat within the end evaporator, then seamlessly transfers it to the high-efficiency NH3 refrigerant in the condensing evaporator. Here, the NH3 refrigerant dispels heat to the surrounding environment through the high-temperature condenser, thus completing the refrigeration cycle with unmatched precision.
Following condensation, the CO2 flows gracefully into the CO2 reservoir. It then navigates through the dryer filter and throttle valve, emerging in the CO2 gas-liquid separator. Propelled by the CO2 circulation pump, the liquid CO2 is channeled to the CO2 evaporator, ensuring superb cooling efficiency. The gaseous CO2 is dynamically compressed by the compressor and circulates back to the condensing evaporator, maintaining a flawless continuous cycle for peak cooling performance.
Discover unparalleled cooling efficiency and steadfast reliability with the groundbreaking cascade refrigeration system offered by Qingdao Bingyan Refrigeration Equipment Co., Ltd. Elevate your refrigeration solutions today and experience a new horizon of cooling excellence!
Advantages of NH3/CO2 Cascade Refrigeration System
Features:
- Reduced NH3 unsafe factors:
- The NH3/CO2 cascade system ingeniously reduces NH3 condensing pressure by a significant 1/10 compared to traditional systems, exemplifying advanced safety measures.
- NH3 is strategically confined to designated areas, significantly enhancing safety and minimizing risk.
- The system expertly harnesses the efficient heat transfer properties of NH3, particularly in high-temperature regions, for exceptional performance.
- CO2 guarantees a high level of safety in personnel-rich environments and extensive warehouse spaces.
- Serving as a low-temperature work medium, CO2 utilizes its exceptional high heat transfer efficiency for optimal function.
