Product Description Product Description NH3/CO2 Cascade Refrigeration System1. NH3/CO2: The Principle of Cascade Refrigeration SystemThe NH3/CO2 cascade refrigeration system is ingeniously designed with two distinct stages: a high-temperature stage utilizing NH3 as the refrigerant, and a low-temperature stage employing CO2. In this sophisticated system, the heat exchange process is initiated by the evaporation of NH3 in the high-temperature segment, which in turn cools and condenses the CO2 refrigerant gas from the low-temperature stage. A cutting-edge condensation evaporator serves as a bridge, connecting these two stages, functioning simultaneously as the condenser for the low-temperature stage and the evaporator for the high-temperature stage. The thermal load is seamlessly transferred to the CO2 refrigerant via the end evaporator. This absorbed heat is then efficiently channeled to the high-temperature NH3 refrigerant through the condensing evaporator. Subsequently, the NH3 refrigerant releases this heat to the environment via a high-temperature condenser, aided by a cooling medium. Post-condensation in the evaporator, CO2 travels to the CO2 reservoir, then progresses through a dryer filter and throttle valve, finally reaching the CO2 gas-liquid separator. The liquid CO2 is fed into the CO2 evaporator via the CO2 circulation pump, bypassing any end cooling device, such as a freezer or chiller. Post-evaporation, the two-phase CO2 returns to the separator, where the gaseous CO2 is compressed and cycled back to the condensing evaporator, perpetuating the innovative cascade refrigeration cycle.In the NH3/CO2 cascade refrigeration system, two separate refrigeration circuits operate harmoniously: the high-temperature NH3 system mirrors traditional refrigeration systems with components like a compressor, condenser, liquid storage, gas-liquid separator, and a throttling device. Conversely, the low-temperature CO2 system complements it with a CO2 compressor, condensing evaporator, reservoir, gas-liquid separator, filter dryer, pump, and expansion vessel, delivering a comprehensive and efficient cooling solution.The CO2 gas-liquid separator plays a crucial role in the CO2 compression refrigeration system by extracting CO2 gas droplets from the evaporator. This prevents the compressor from wet strokes, maintains a consistent liquid level during pump operation, and accommodates liquid return when the pump halts. If used as a CO2 reservoir during downtime, the separator's capacity should be ample to store all system CO2 liquid. An auxiliary evaporator atop the separator ensures CO2 pressure remains controlled post-shutdown. Within the NH3/CO2 system, the condensing evaporator doubles as the NH3 side's evaporator and the CO2 side's condenser, where compound liquids vaporize and absorb heat while CO2 gas liquefies in the shell.2. Advantages of the NH3/CO2 Cascade Refrigeration System(1) Significant Reduction in NH3 Risks:(1.(1)) The NH3/CO2 cascade refrigeration system dramatically minimizes the condensing pressure of the NH3 refrigerant charge to about 1/10 of that in conventional ammonia systems, enhancing safety.(1.(2)) NH3 is confined within the machine room, effectively monitored by skilled technicians, akin to a 'tiger' safely caged.(1.(3)) The system maximizes the excellent heat transfer attributes of NH3 in high-temperature zones to efficiently cool CO2.(2) CO2 as a Medium: This system safely channels CO2 into personnel-heavy areas like operational rooms and warehouses, ensuring safety for both staff and assets.7c686dfbProduct ParametersCompressor typePiston, screwCondensorenough condenser heat exchanger surfaceFan typeAxial fan:High degree of protection, large Air flow, low noiseUnit kindsOpen type, box type, side discharge typeCooled typeAir cooledRefrigeration typeR717;R507;R22;CO2Copper tube connector fitting reducerPlace to assembleIndoor/out door(concrete construction building/steel construction building).Voltage220V/50HZ, 220V/60HZ, 380V/50HZ etcController Automatic electric controller, PLCWarranty1 YearCase materialThe galvanized sheet is coated with plastic powdered paintedQuality Assurance2.6Mpa leak-proof stress test PackagePlywood box and palletQingdao Bingyan Refrigeration Equipment Co., Ltd. is a premier manufacturer committed to meeting your specific needs with our High Capacity Refrigeration Compressor for Industrial Cold Storage.
