Introducing the state-of-the-art cascade refrigeration system by Qingdao Bingyan Refrigeration Equipment Co., Ltd. This groundbreaking system harnesses the power of CO2 and NH3 refrigerants to deliver unparalleled cooling performance. The CO2 refrigerant adeptly absorbs heat in the end evaporator, facilitating a seamless transfer to the high-temperature NH3 refrigerant within the condensing evaporator. The NH3 refrigerant, now at a high temperature, efficiently dissipates heat to the environment through the high-temperature condenser, thereby completing a masterfully engineered refrigeration cycle.
The condensed CO2 seamlessly flows into the CO2 reservoir and is then expertly guided through the CO2 gas-liquid separator via the dryer filter and throttle valve. Empowered by the robust CO2 circulation pump, the liquid CO2 advances to the CO2 evaporator, ensuring efficient and consistent cooling. The gaseous CO2 is subsequently compressed by the compressor and returned to the condensing evaporator, perpetuating a continuous cycle for optimal cooling results.
