Introducing the revolutionary cascade refrigeration system by Qingdao Bingyan Refrigeration Equipment Co., Ltd. This state-of-the-art system masterfully transfers heat loads using the cutting-edge CO2 and NH3 refrigerants, guaranteeing exceptional cooling efficiency. The CO2 refrigerant captures heat in the end evaporator, which is then expertly transferred to the high-temperature NH3 refrigerant within the condensing evaporator. This ingenious process allows the high-temperature NH3 refrigerant to release heat to the environment through the high-temperature condenser, flawlessly completing the refrigeration cycle.
The condensed CO2 seamlessly flows into the CO2 reservoir, traversing the CO2 gas-liquid separator via the dryer filter and throttle valve. With the CO2 circulation pump assisting, the liquid CO2 is expertly guided to the CO2 evaporator for superior cooling. The gaseous CO2 is then compressed by the compressor and efficiently returned to the condensing evaporator, ensuring an uninterrupted cycle for peak cooling performance.
