Introducing the innovative cascade refrigeration system by Qingdao Bingyan Refrigeration Equipment Co., Ltd. This cutting-edge system expertly manages heat load transfer using the powerful combination of CO2 and NH3 refrigerants. This design ensures exceptional cooling performance. At the core of this process, CO2 refrigerant actively absorbs heat within the end evaporator. This absorbed heat is then efficiently transferred to the high-temperature NH3 refrigerant found in the condensing evaporator. The high-temperature NH3 refrigerant, in turn, dissipates heat into the environment through the high-temperature condenser, effectively completing the refrigeration cycle.
The process continues as the condensed CO2 makes its way into the CO2 reservoir. It then flows gracefully through the CO2 gas-liquid separator, passing through the dryer filter and throttle valve with precision. Propelled by the efficient CO2 circulation pump, the liquid CO2 is delivered to the CO2 evaporator, ensuring optimal cooling. Meanwhile, the gaseous CO2 undergoes compression by the compressor before returning to the condensing evaporator. This holistic process guarantees a seamless cycle, ensuring peak cooling performance at all times.
