NH3/CO2 Cascade Refrigeration System
1. Exploring the Principle of the NH3/CO2 Cascade Refrigeration System
Delve into the intricate design of the NH3/CO2 cascade refrigeration system, ingeniously divided into two crucial stages: the high-temperature stage harnessing NH3 as its refrigerant, and the low-temperature stage utilizing CO2. Marvel at the clever interplay between stages where the evaporation of NH3 refrigerant at the high-temperature level meticulously condenses the CO2 refrigerant gas emitted from the low-temperature level. This sophisticated mechanism employs a condensation evaporator to seamlessly unite the dual stages, acting as both the low-temperature condenser and the high-temperature evaporator.
Experience the seamless transfer of heat load, efficiently channeled to the CO2 refrigerant through the terminal evaporator. The CO2 refrigerant absorbs heat and then adeptly transfers it to the high-temperature NH3 refrigerant via the condensing evaporator. The high-temperature NH3 refrigerant further dispatches heat to the high-temperature condenser, releasing it into the environment with the help of the cooling medium. Witness the intricate journey as condensed CO2 journeys from the condensing evaporator to the CO2 reservoir, then traverses through the dryer filter and throttle valve to enter the CO2 gas-liquid separator. In a symphony of engineering, liquid CO2 is propelled to the CO2 evaporator by the CO2 circulation pump, ultimately cycling back to the gas-liquid separator post-evaporation. Gaseous CO2 is meticulously compressed back into the condensing evaporator by the compressor, perpetuating this elegant cycle of cascade refrigeration.
The NH3/CO2 cascade refrigeration system is an exemplar of precision, with high and low temperature levels operating as distinct refrigeration systems, each employing a single refrigerant. The high-temperature NH3 refrigeration segment mirrors a conventional setup, boasting components like the refrigeration compressor, condenser, liquid storage, gas-liquid separator, and throttling device. In contrast, the low-temperature CO2 refrigeration system encompasses a CO2 compressor, condensing evaporator, reservoir, gas-liquid separator, filter dryer, pump, throttling device, evaporator, and expansion vessel, creating a harmonious synergy of components.
The In the sophisticated CO2 compression refrigeration system, the CO2 gas-liquid separator serves a pivotal role. It deftly separates CO2 gas droplets emanating from the evaporator, safeguarding the compressor against the perils of a wet stroke. This separator ensures a stable liquid level during pump operation and efficiently stores end equipment and pipeline liquid upon pump cessation. Remarkably, when the system is inactive, the gas-liquid separator doubles as a CO2 reservoir, boasting a volume capacious enough to house the entirety of the system's CO2 liquid. To mitigate excessive CO2 pressure post-shutdown, an auxiliary evaporator is strategically positioned atop the gas-liquid separator. Intriguingly, within the NH3/CO2 cascade refrigeration system, the condensing evaporator dualizes as both the NH3 side evaporator and the CO2 side condenser, wherein compound liquid evaporates and absorbs heat within the tube while CO2 gas condenses into a liquid within the shell.
2. The Advantages of the NH3/CO2 Cascade Refrigeration System
(1) Enhanced Safety through Reduced NH3 Risk Factors:
(1.(1)) This innovative NH3/CO2 cascade refrigeration system significantly diminishes the condensing pressure of NH3 refrigerant charge, curbing it to approximately 1/10th of the traditional ammonia refrigeration system charge.
(1.(2)) NH3 is strategically confined to the machine and equipment rooms, akin to a 'tiger' safely ensconced within a 'cage', vigilantly overseen by skilled professionals.
(1.(3)) The system fully capitalizes on NH3's excellent heat transfer properties in high-temperature regions, utilizing it to effectively cool CO2.
(2) CO2 is introduced as a medium into personnel-heavy operational areas, such as single-freezing machines and warehouses, ensuring the safety of both personnel and property.
