NH3/CO2 Cascade Refrigeration System
1. NH3/CO2: The Principle Behind Cascade Refrigeration System
Delve into the innovative NH3/CO2 cascade refrigeration system, which seamlessly integrates two distinct yet harmonious parts: a high-temperature stage utilizing NH3 as the refrigerant and a low-temperature stage harnessing CO2. This ingenious design employs the evaporation of NH3 in the high-temperature section to effectively condense the CO2 gas from the low-temperature stage. A sophisticated condensation evaporator acts as the bridge between these stages, serving as the condenser for the low temperature and the evaporator for the high temperature, ensuring optimal performance.
Experience the remarkable heat transfer efficiency of this system, where the heat load is seamlessly transferred to the CO2 refrigerant via the end evaporator. This absorbed heat is then conveyed to the robust high-temperature NH3 refrigerant through the condensing evaporator, which subsequently releases the heat into the environment through a high-temperature condenser, aided by a cooling medium. The condensed CO2 is expertly managed by a CO2 reservoir, progressing through a dryer filter and throttle valve before making its way to the CO2 gas-liquid separator. The liquid CO2 is efficiently directed to the CO2 evaporator via a circulation pump. Following evaporation, the two-phase CO2 returns to the gas-liquid separator, and the gaseous CO2 is adeptly compressed and cycled back into the condensing evaporator, perpetuating the cycle with precision.
In the NH3/CO2 cascade refrigeration system, distinction is drawn between the high and low-temperature levels, each operating as single-refrigerant systems. The high-temperature NH3 system mirrors conventional refrigeration designs, featuring elements such as the refrigeration compressor, condenser, liquid storage, gas-liquid separator, and throttling device. The low-temperature CO2 system, meanwhile, is enriched with components including a CO2 compressor, condensing evaporator, reservoir, gas-liquid separator, filter dryer, pump, throttling apparatus, evaporator, and expansion vessel, ensuring a comprehensive and efficient setup.
The CO2 Gas-Liquid Separator is engineered to meticulously extract CO2 gas droplets from the evaporator in the CO2 compression refrigeration system, safeguarding the compressor against wet strokes, maintaining a stable liquid level during pump operation, and securely storing end equipment and pipeline liquid return when the pump is idle. When the gas-liquid separator doubles as a CO2 reservoir during non-operation, its capacity is designed to accommodate all CO2 liquid within the system. Additionally, an auxiliary evaporator atop the gas-liquid separator ensures CO2 pressure does not escalate post-shutdown. Within the NH3/CO2 cascade system, the condensing evaporator uniquely performs dual roles: acting as an evaporator on the NH3 side and a condenser on the CO2 side, where compound liquid evaporates and absorbs heat inside the tube, while carbon dioxide condenses into liquid within the shell.
2. Distinct Advantages of the NH3/CO2 Cascade Refrigeration System
(1) Minimized NH3 Safety Concerns:
(1.(1)) The NH3/CO2 cascade refrigeration system dramatically reduces the condensing pressure of the NH3 refrigerant charge to approximately 1/10th of what traditional ammonia systems require, ensuring safer operations;
(1.(2)) NH3 is strategically confined within the machine room and equipment room, effectively akin to a 'tiger' within a 'cage', safeguarded by skilled technical professionals;
(1.(3)) Efficiently exploits NH3’s superior heat transfer properties in the high-temperature region for cooling CO2.
(2) CO2 as a Versatile Medium: CO2 is a versatile refrigerant that safely integrates into personnel-intensive areas, such as single-freezing machines and warehouses, ensuring the wellbeing of both individuals and assets.
