Revolutionary NH3/CO2 Cascade Refrigeration System
1. Innovative Principle of NH3/CO2 Cascade Refrigeration System
NH3/CO2, a cascade refrigeration marvel, operates through two meticulously designed stages: a high-temperature stage employing NH3 as the refrigerant, and a low-temperature stage utilizing CO2. In this advanced system, the evaporation of NH3 in the high-temperature stage efficiently condenses the CO2 gas discharged from the low-temperature stage. A sophisticated condensation evaporator seamlessly connects these stages, functioning dually as the low-temperature condenser and the high-temperature evaporator.
Harnessing the heat load, the CO2 refrigerant absorbs thermal energy through the end evaporator and transfers it gracefully to the high-temperature NH3 refrigerant via the condensing evaporator. The NH3, in turn, transfers the heat to a high-temperature condenser, releasing it to the environment using a cooling medium. The condensed CO2 is then channeled into a CO2 reservoir, advancing through a dryer filter and throttle valve to the CO2 gas-liquid separator. Liquid CO2 is propelled to the CO2 evaporator by a circulation pump, devoid of an end cooling device. Post-evaporation, the bi-phase CO2 returns to the separator. Gaseous CO2 is then compressed into the condensing evaporator by the compressor, perpetuating this efficient cascade refrigeration cycle.
In the NH3/CO2 cascade refrigeration system, each temperature level is powered by a dedicated refrigerant. The high-temperature NH3 system mirrors conventional setups with components like a refrigeration compressor, condenser, liquid storage, gas-liquid separator, and throttling device. Conversely, the low-temperature CO2 system is equipped with a CO2 compressor, condensing evaporator, reservoir, gas-liquid separator, filter dryer, pump, throttling device, evaporator, and expansion vessel, embodying cutting-edge refrigeration technology.
The CO2 gas-liquid separator plays a pivotal role in ensuring optimal performance in the CO2 compression refrigeration system. It meticulously separates CO2 gas droplets from the evaporator, protecting the compressor from wet strokes. It maintains a stable liquid level during pump operation and securely stores liquid return from terminal equipment and pipelines during pump shutdowns. When not in operation, this gas-liquid separator can double as a CO2 reservoir, accommodating all system liquid. An auxiliary evaporator at its peak prevents excessive CO2 pressure post-shutdown. In the NH3/CO2 cascade system, the condensing evaporator performs dual roles: NH3 side evaporator and CO2 side condenser, where compound liquids evaporate and carbon dioxide gas is elegantly condensed into liquid form.
2. Exceptional Advantages of the NH3/CO2 Cascade Refrigeration System.
(1) Enhanced Safety and Reduced NH3 Risks:
(1.(1)) The NH3/CO2 cascade refrigeration system significantly curtails the condensing pressure of NH3, reducing it to merely 1/10th of traditional ammonia systems;
(1.(2)) NH3 is securely contained within machine and equipment rooms, akin to a 'tiger in a cage', under strict professional supervision;
(1.(3)) Maximizes NH3's excellent heat transfer capabilities in high-temperature zones for optimal CO2 cooling.
(2) Introducing CO2 as a safe medium in personnel-intensive areas, such as production rooms and warehouses, ensuring the utmost safety for personnel and assets.
