Introducing the revolutionary cascade refrigeration system from the esteemed Qingdao Bingyan Refrigeration Equipment Co., Ltd. This state-of-the-art system masterfully manages heat transfer with unparalleled efficiency, utilizing the powerful refrigerants CO2 and NH3. The CO2 refrigerant adeptly absorbs heat at the end evaporator stage, seamlessly transferring it to the high-temperature NH3 refrigerant in the condensing evaporator. Subsequently, the high-temperature NH3 refrigerant expertly releases heat to the surroundings via the high-temperature condenser, culminating a highly efficient refrigeration cycle.
The journey of condensed CO2 continues as it flows gracefully into the CO2 reservoir, subsequently navigating through the CO2 gas-liquid separator, dryer filter, and throttle valve. Empowered by the CO2 circulation pump, the liquid CO2 embarks on its mission to the CO2 evaporator, delivering unparalleled cooling efficiency. The gaseous CO2 is then skillfully compressed by the compressor and returns to the condensing evaporator, perpetuating a seamless cycle for unmatched cooling performance.
Elevate your cooling solutions with the exceptional efficiency and unwavering reliability of the cascade refrigeration system by Qingdao Bingyan Refrigeration Equipment Co., Ltd. Transform your refrigeration framework today and experience the difference!
