NH3/CO2 Cascade Refrigeration System: A Cutting-edge Solution for Optimal Cooling
1. NH3/CO2: The Ingenious Principle Behind the Cascade Refrigeration System
The NH3/CO2 cascade refrigeration system is a marvel of engineering, comprising two distinct yet harmoniously integrated stages: the high-temperature stage utilizes NH3 as the refrigerant, while the low-temperature stage employs CO2. This innovative design operates by using the evaporation of NH3 in the high-temperature stage to effectively condense CO2 gas from the low-temperature stage. The system is ingeniously interconnected by a condensation evaporator that serves a dual purpose: acting as both the condenser for the low-temperature stage and the evaporator for the high-temperature stage, thus optimizing energy efficiency and enhancing cooling performance.
In this sophisticated cycle, heat is meticulously transferred to CO2 via the end evaporator. The absorbed heat from the CO2 is then efficiently transferred to NH3 in the high-temperature stage through a condensing evaporator. NH3 further releases the heat to the environment via a high-temperature condenser, ensuring exceptional thermal management. Condensed CO2 is directed into the CO2 reservoir and subsequently navigates through a dryer filter and throttle valve into the CO2 gas-liquid separator. The liquid CO2 is propelled to the CO2 evaporator by a circulation pump, ensuring a seamless flow in the absence of an end cooling device. The post-evaporator two-phase CO2 reverts to the gas-liquid separator, where gaseous CO2 is drawn by the compressor and compressed back into the condensing evaporator, maintaining a continuous high-efficiency cascade refrigeration cycle.
In the NH3/CO2 cascade refrigeration system, each temperature level is a single refrigerant system, expertly crafted to maximize its unique properties. The high-temperature NH3 system mirrors conventional refrigeration systems and includes essential components such as a refrigeration compressor, condenser, liquid storage, gas-liquid separator, and throttling device. Conversely, the low-temperature CO2 system boasts an array of advanced components: CO2 compressor, condensing evaporator, reservoir, gas-liquid separator, filter dryer, pump, throttling device, evaporator, and expansion vessel, each meticulously engineered to deliver unparalleled cooling performance.
The The CO2 gas-liquid separator plays a critical role in the CO2 compression refrigeration system, effectively isolating CO2 gas droplets from the evaporator. This ensures a dry stroke for the compressor, maintains a stable liquid level during pump operation, and efficiently stores returned liquid from equipment and pipelines when the pump ceases operation. When used as a CO2 reservoir, its capacity must accommodate the entire CO2 liquid volume of the system. An auxiliary evaporator is strategically positioned atop the gas-liquid separator to prevent excessive CO2 pressure post-shutdown. In the NH3/CO2 cascade system, the condensing evaporator functions as both the NH3-side evaporator and the CO2-side condenser, with compound liquids evaporating and absorbing heat within the tube, while CO2 gas condenses into liquid within the shell.
2. The Unmatched Advantages of the NH3/CO2 Cascade Refrigeration System
(1) Minimizing NH3 Safety Risks for Enhanced Peace of Mind:
(1.(1)) The NH3/CO2 cascade refrigeration system significantly reduces NH3 pressure requirements, cutting it down to approximately 1/10 of traditional ammonia systems, thereby elevating safety margins.
(1.(2)) NH3 is confined to designated machine and equipment rooms, akin to a 'tiger in a cage,' under the vigilant supervision of skilled technicians, ensuring ultimate safety.
(1.(3)) It harnesses NH3's superior heat transfer capabilities in high-temperature zones to effectively cool CO2, maximizing energy efficiency.
(2) CO2: A Safe Medium for Occupied Areas and Storage Facilities, Prioritizing People and Property Safety
