Introducing the Innovative NH3/CO2 Cascade Refrigeration System
1. Discovering the Power of the NH3/CO2 Cascade Refrigeration System
The NH3/CO2 cascade refrigeration system is a marvel of engineering, ingeniously split into two dynamic stages: the high-temperature stage, powered by NH3 as the refrigerant, and the low-temperature stage, utilizing CO2. The system operates seamlessly as NH3 evaporates in the high-temperature stage, masterfully condensing CO2 gas from the low-temperature stage. This is achieved through a unique condensation evaporator that serves a dual purpose: it's both the condenser for the low-temperature stage and the evaporator for the high-temperature stage.
In this cutting-edge system, heat is efficiently transferred to the CO2 refrigerant through the end evaporator. The absorbed heat in the CO2 refrigerant is then deftly transferred to the high-temperature NH3 refrigerant via the condensing evaporator. The NH3 refrigerant subsequently disperses this heat to the high-temperature condenser, releasing it to the atmosphere through a cooling medium. The cycle continues as condensed CO2 enters the CO2 reservoir, moving through a dryer filter and throttle valve to the CO2 gas-liquid separator. Liquid CO2 is propelled to the CO2 evaporator by the CO2 circulation pump (operating without an end cooling device such as a single freezer or chiller). Post-evaporation, the two-phase CO2 returns to the gas-liquid separator, with gaseous CO2 being compressed back into the condensing evaporator by the compressor, thus perpetuating the efficient cascade refrigeration cycle.
Within the NH3/CO2 cascade refrigeration system, high and low-temperature stages each utilize a single refrigerant, forming distinct yet interconnected systems. The high-temperature NH3 refrigeration system mirrors conventional systems, featuring not only a refrigeration compressor but also a condenser, liquid storage, gas-liquid separator, and throttling device. The low-temperature CO2 refrigeration system is equally advanced, boasting a CO2 compressor, condensing evaporator, reservoir, gas-liquid separator, filter dryer, pump, throttling device, evaporator, and expansion vessel.
The The CO2 gas-liquid separator plays a pivotal role in the CO2 compression refrigeration system, expertly separating droplets from the gas to prevent compressor malfunctions, ensure a stable liquid level during pump operation, and manage liquid return when the pump halts. When used as a CO2 reservoir during inactivity, its capacity must accommodate all system CO2 liquid. An auxiliary evaporator atop the separator effectively mitigates excessive CO2 pressure post-shutdown. In the NH3/CO2 cascade system, the condensing evaporator acts dually as an evaporator on the NH3 side and a condenser on the CO2 side, where compound liquid evaporation and heat absorption occur in the tube, while CO2 gas condenses into liquid in the shell.
2. Unmatched Advantages of the NH3/CO2 Cascade Refrigeration System
(1) A Safer Alternative with Reduced NH3 Risks:
(1.(1))The NH3/CO2 cascade refrigeration system ingeniously minimizes NH3 condensing pressure, requiring just about 1/10th of the traditional ammonia system charge.
(1.(2))NH3 is securely confined within the machine room, akin to a 'tiger in a cage,' safeguarded by skilled professionals.
(1.(3))The system fully capitalizes on NH3's superior heat transfer properties in high-temperature zones to effectively cool CO2.
(2) CO2 as a medium enhances safety in personnel-dense operational areas (such as single-freezing machines) and storage facilities, prioritizing the well-being of personnel and property.
