NH3/CO2 Cascade Refrigeration System
1. NH3/CO2 Cascade Refrigeration System Principles
The NH3/CO2 Cascade Refrigeration System ingeniously combines two distinct stages: a high-temperature stage employing NH3 as the refrigerant and a low-temperature stage utilizing CO2. The brilliance of this system lies in its ability to use the evaporative cooling of NH3 in the high-temperature system to condense the CO2 refrigerant gas from the low-temperature system. This is achieved through a sophisticated condensation evaporator that seamlessly interlinks the high and low-temperature layers, serving a dual purpose as both the low-temperature condenser and the high-temperature evaporator.
In our advanced system, thermal energy is meticulously transferred to the CO2 refrigerant via the terminal evaporator. Subsequently, the heat absorbed by the CO2 is passed onto the NH3 refrigerant through the condensing evaporator. This NH3 refrigerant then releases the accumulated heat to the environment via a high-temperature condenser. The subsequent steps involve the cooled CO2 entering the CO2 reservoir, followed by a journey through the dryer filter and throttle valve to the CO2 gas-liquid separator. A CO2 circulation pump efficiently propels the liquid CO2 to the evaporator, completing a revolutionary cycle that excels in thermal management without end-cooling devices like single freezers. Post-evaporation, the CO2 transitions back to the gas-liquid separator, where it is compressed and reintroduced into this groundbreaking cycle.
Within the NH3/CO2 cascade system, our solution elegantly divides into two unique refrigerant systems. The high-temperature NH3 system mirrors conventional refrigeration yet stands out with components like the refrigeration compressor, condenser, liquid storage, and separators. The low-temperature CO2 system boasts an array of cutting-edge components including the CO2 compressor and condensing evaporator, enhancing efficiency with a reservoir, separator, dryer, circulation pump, and expansion vessel, all orchestrating a symphony of cooling.
The The CO2 Gas-Liquid Separator is a marvel of engineering, effectively isolating CO2 droplets from the evaporator in the compression system. This ensures smooth operation by preventing compressor wet strokes and maintaining stable liquid levels, even during pump stops. When utilized as a reservoir, the separator's capacity accommodates the entire CO2 liquid volume, ensuring no system overload. An auxiliary evaporator atop the separator safeguards against excessive pressures post-shutdown. In this cascade system, the condensing evaporator performs dual roles: acting as an NH3 evaporator and a CO2 condenser, facilitating seamless heat absorption and condensation processes.
2. Advantages of the NH3/CO2 Cascade Refrigeration System
(1) Enhanced Safety with Reduced NH3 Exposure:
(1.(1)) This innovative system dramatically minimizes NH3 condensing pressure, only about 1/10th of that in traditional ammonia systems, ensuring safer operation.
(1.(2)) NH3 is securely confined within machinery and equipment rooms, creating a 'tiger in a cage' environment, monitored by expert personnel.
(1.(3)) The system capitalizes on NH3's exceptional heat transfer capabilities in high-temperature regions to effectively cool CO2.
(2) CO2 serves as a safer medium in high-traffic areas, such as operation rooms and warehouses, safeguarding personnel and assets.
