NH3/CO2 Cascade Refrigeration System: A Cutting-Edge Solution
1. NH3/CO2: The Ingenious Principle Behind the Cascade Refrigeration System
NH3/CO2 Cascade Refrigeration System: A dual-stage marvel that seamlessly integrates high and low temperature components. The high-temperature stage utilizes NH3 as the refrigerant while the low-temperature stage employs CO2. The brilliance lies in how the evaporation of NH3 at the high temperature level efficiently condenses CO2 gas from the low temperature level, creating a synchronized harmony. A condensation evaporator serves as the connecting linchpin, acting dually as the condenser for CO2 and the evaporator for NH3.
In this meticulously designed system, the heat load gracefully transfers to the CO2 refrigerant through the end evaporator. Subsequently, the CO2 refrigerant's absorbed heat is deftly transferred to the NH3 refrigerant via the condensing evaporator. Further on, the NH3 refrigerant dispatches the heat to a high-temperature condenser, releasing it into the environment with poise. Following this, the condensed CO2 enters a CO2 reservoir, making its way through a dryer filter and throttle valve to the gas-liquid separator. The magic continues as the CO2 circulation pump propels the liquid CO2 to the CO2 evaporator. Post-evaporation, the two-phase CO2 returns to the separator, where gaseous CO2 is compressed back into the condensing evaporator, perpetually rejuvenating the cascade cycle.
NH3/CO2 Cascade System: Ingenious in its dual-level, single-refrigerant operation, delineating equipment into two precise segments. The high-temperature NH3 refrigeration section mirrors conventional systems with compressors, condensers, liquid storage, and gas-liquid separators. The low-temperature CO2 section enhances with components like condensing evaporators, reservoirs, filters, dryers, pumps, and expansion vessels, providing a holistic approach to refrigeration.
The The CO2 gas-liquid separator is an essential innovation, ensuring droplets from the evaporator in the CO2 compression system are effectively separated to prevent compressor wet strokes. This vital component maintains a stable liquid level during pump operations and stores return liquid when the pump halts. Ingeniously, when not operational, it doubles as a CO2 reservoir, capable of containing all system liquid. An auxiliary evaporator shields against excessive post-shutdown CO2 pressure. In the NH3/CO2 cascade, the condensing evaporator brilliantly serves dual roles, evaporating compounds on the NH3 side while condensing CO2 into liquid form on the shell side.
2. The Remarkable Advantages of NH3/CO2 Cascade Refrigeration System
(1) NH3 Safety Enhancement: A Revolutionary Leap
(1.(1)) The NH3/CO2 system dramatically reduces NH3's condensing pressure, scaling down to merely 1/10th of traditional ammonia systems, ensuring unparalleled safety.
(1.(2)) The NH3 element is confined to machine and equipment rooms, akin to a 'tiger in a cage,' meticulously monitored by expert personnel.
(1.(3)) Optimal utilization of NH3's superior heat transfer qualities in high-temperature regions, effectively harnessed to cool CO2.
(2) CO2: A Safe Medium for High-Personnel Areas
