Introducing the NH3/CO2 Cascade Refrigeration System
1. The Ingenious Principle of NH3/CO2 Cascade Refrigeration System
The NH3/CO2 cascade refrigeration system is a marvel of engineering, seamlessly integrating two stages: a high-temperature stage utilizing NH3 as the refrigerant and a low-temperature stage employing CO2. In this sophisticated system, the evaporation of NH3 at the high-temperature level effectively condenses the CO2 refrigerant emanating from the low-temperature level. The two stages are skillfully bridged by a condensation evaporator, serving dual roles as both the condenser for the low-temperature stage and the evaporator for the high-temperature stage.
In this advanced system, the heat load is efficiently transferred to the CO2 refrigerant via the end evaporator. The absorbed heat of the CO2 is then effortlessly transferred to the high-temperature NH3 refrigerant through the condensing evaporator. The high-temp NH3 refrigerant skillfully disperses the heat to the high-temp condenser, which releases it to the environment using a cooling medium. Post condensation at the condensing evaporator, CO2 enters the CO2 reservoir, subsequently making its way through the dryer filter and throttle valve into the CO2 gas-liquid separator. With precision, the liquid CO2 is transported to the CO2 evaporator by the circulation pump. Following this, the two-phase CO2 returns to the gas-liquid separator, where gaseous CO2 is compressed by the compressor back into the condensing evaporator, perpetuating the cycle with unmatched efficiency.
Within the NH3/CO2 cascade refrigeration system, the high and low temperature levels operate as distinct refrigeration systems, each utilizing a single refrigerant. The high-temperature NH3 refrigeration system mirrors conventional systems, featuring a refrigeration compressor, condenser, liquid storage, gas-liquid separator, and a throttling device. On the other hand, the low-temperature CO2 refrigeration system boasts components like a CO2 compressor, condensing evaporator, reservoir, gas-liquid separator, filter dryer, pump, throttling device, evaporator, and expansion vessel, all ingeniously assembled to deliver superior performance.
The In the realm of CO2 compression refrigeration systems, the CO2 gas-liquid separator plays a pivotal role. It meticulously separates CO2 gas droplets from the evaporator, safeguarding the compressor from wet strokes and maintaining a stable liquid level during pump operation. It also offers crucial functionality as a reservoir, capable of accommodating the entire system's CO2 liquid when not in use. To counteract high CO2 pressure post-shutdown, an auxiliary evaporator strategically atop the gas-liquid separator proves invaluable. Within the NH3/CO2 cascade refrigeration system, the condensing evaporator serves a dual purpose, functioning as both the evaporator on the NH3 side and the condenser on the CO2 side, optimizing heat absorption and CO2 gas condensation into a liquid.
2. The Remarkable Advantages of the NH3/CO2 Cascade Refrigeration System
(1) Enhanced Safety by Reducing NH3 Risks:
(1.(1)) The NH3/CO2 cascade refrigeration system significantly minimizes NH3 condensing pressure, approximately only 1/10 of traditional ammonia systems, heralding a new era of safety.
(1.(2)) NH3 is contained within controlled environments like machine rooms, akin to a 'tiger in a cage,' safeguarded by skilled professionals, ensuring unparalleled safety.
(1.(3)) The system harnesses NH3's excellent heat transfer capabilities in high-temperature regions, optimizing CO2 cooling.
(2) By introducing CO2 as a medium in personnel-intensive areas, such as single-freezing machines and warehouses, the system ensures the utmost safety and protection of both people and property.
