NH3/CO2 Cascade Refrigeration System
1. NH3/CO2: The Ingenious Principle of Cascade Refrigeration System
The NH3/CO2 cascade refrigeration system is a marvel of engineering, elegantly composed of two distinct yet harmonized segments: a high temperature stage and a low temperature stage. In this innovative setup, ammonia (NH3) is the refrigerant of choice for the high temperature stage, while carbon dioxide (CO2) reigns supreme in the low temperature stage. The brilliance of this system lies in its use of evaporated NH3 from the high temperature level to effectively condense CO2 gas discharged from the low temperature level. A sophisticated condensation evaporator acts as a conduit linking both the high and low temperature stages, serving a dual purpose as both a condenser for the low temperature level and an evaporator for the high temperature level.
In this sophisticated system, the heat load is efficiently transferred to the CO2 refrigerant via the end evaporator. The CO2 refrigerant, having absorbed this heat, subsequently transfers it to the high-temperature NH3 refrigerant through the condensing evaporator. The NH3 refrigerant then elegantly transfers the accumulated heat to the high-temperature condenser, releasing it into the environment with grace and efficiency through a cooling medium. As the CO2 condenses in the condensing evaporator, it journeys to the CO2 reservoir before venturing into the CO2 gas-liquid separator, with the aid of a dryer filter and throttle valve. The cycle continues as liquid CO2 is propelled to the CO2 evaporator by the CO2 circulation pump, bypassing additional cooling devices. Post-evaporation, the two-phase CO2 returns to the gas-liquid separator, where gaseous CO2 is aspirated by the compressor, compressed, and returned to the condensing evaporator, thus perpetuating this seamless cascade refrigeration cycle.
In the NH3/CO2 cascade refrigeration system, each temperature level is a masterpiece of refrigeration technology, using a single refrigerant to optimize efficiency. The high-temperature NH3 refrigeration system mirrors a conventional setup, complete with a refrigeration compressor, condenser, liquid storage, gas-liquid separator, and throttling device. Meanwhile, the low temperature CO2 refrigeration system is a marvel in its own right, encompassing a CO2 compressor, condensing evaporator, reservoir, gas-liquid separator, filter dryer, pump, throttling device, evaporator, and an expansion vessel, all working in symphony to ensure optimal performance.
The The CO2 gas-liquid separator is an essential component that expertly isolates CO2 gas droplets from the evaporator within the CO2 compression refrigeration system, preventing the detrimental wet stroke phenomenon in compressors. It maintains a stable liquid level during pump operation and safely stores equipment and pipeline liquid return when the pump ceases operation. Acting as a reservoir during downtime, it must possess the capacity to contain all liquid CO2. Additionally, an auxiliary evaporator atop the gas-liquid separator safeguards against excessive CO2 pressure post-shutdown. In the NH3/CO2 cascade system, the condensing evaporator doubles as an evaporator on the NH3 side and a condenser on the CO2 side, with compound liquid evaporating to absorb heat within, while CO2 gas condenses into liquid in the shell.
2. Unveiling the Advantages of the NH3/CO2 Cascade Refrigeration System
(1) Enhanced Safety with NH3:
(1.(1)) The NH3/CO2 cascade refrigeration system significantly diminishes the condensing pressure of the NH3 refrigerant charge, reducing it to an impressive 1/10th of the traditional ammonia refrigeration system's charge.
(1.(2)) NH3 is securely confined to the machine and equipment rooms, akin to a 'tiger in a cage,' diligently monitored by skilled technical personnel.
(1.(3)) The system maximizes the excellent heat transfer properties of NH3 in the high-temperature zone, employing it to cool CO2 efficiently.
(2) CO2 serves as a safe medium in densely populated areas, such as single-freezing machines and warehouses, ensuring the utmost safety for both personnel and property.
