Revolutionary NH3/CO2 Cascade Refrigeration System
1. Unveiling the Principle Behind NH3/CO2 Cascade Refrigeration Systems
The NH3/CO2 cascade refrigeration system is ingeniously crafted, comprising two distinct sections: a high temperature stage utilizing NH3 as the refrigerant and a low temperature stage employing CO2. In this sophisticated setup, the NH3 refrigerant evaporates at high temperatures to condense the CO2 gas emanating from the low temperature stage. A condensation evaporator artfully links these high and low-temperature stages, serving dual roles—acting as the low temperature condenser and the high temperature evaporator.
Within this advanced system, the heat load seamlessly transfers to the CO2 refrigerant via the end evaporator. CO2 then efficiently absorbs this heat, transferring it to high-temperature NH3 via the condensing evaporator. The high-temperature NH3 refrigerant subsequently channels the heat to the high-temperature condenser, releasing it to the environment with the aid of a cooling medium. Condensed CO2 in the evaporator moves into the CO2 reservoir, proceeding through a dryer filter and throttle valve to a gas-liquid separator. It then flows through a CO2 circulation pump to the evaporator. Post-evaporation, two-phase CO2 returns to the separator, and the gaseous CO2 is compressed back into the condensing evaporator, perpetuating the cascade cycle.
In the NH3/CO2 cascade refrigeration framework, each temperature stage functions as an independent refrigerant system. The high-temperature NH3 system mirrors conventional setups, comprising a compressor, condenser, liquid storage, gas-liquid separator, and throttling device. Meanwhile, the low-temperature CO2 system encompasses a CO2 compressor and includes a condensing evaporator, reservoir, gas-liquid separator, filter dryer, pump, throttling device, evaporator, and expansion vessel, each contributing to the system's unrivaled efficiency.
The The CO2 gas-liquid separator plays a pivotal role by isolating CO2 gas droplets post-evaporation, safeguarding the compressor from wet strokes, and maintaining stable liquid levels during pump operation. It serves a dual function by storing pipeline liquid return when the pump halts. When inactive, it can hold all the CO2 liquid within the system, complemented by an auxiliary evaporator atop the separator to prevent excessive CO2 pressure post-shutdown. Within the NH3/CO2 cascade system, the condensing evaporator is a marvel, functioning as both the NH3 evaporator and CO2 condenser. Here, compound liquids evaporate and absorb heat internally, while carbon dioxide is efficiently condensed.
2. Exalting the Advantages of the NH3/CO2 Cascade Refrigeration System
(1) Amplified Safety through Reduced NH3 Risks:
(1.(1))The NH3/CO2 cascade system remarkably minimizes NH3 condensing pressure, slashing it to just 1/10 of conventional ammonia systems.
(1.(2))NH3 is strategically confined to machine and equipment rooms, akin to a 'tiger' in a 'cage,' expertly managed by skilled personnel.
(1.(3))Leveraging NH3's superior heat transfer properties at high temperatures, it serves to cool CO2 efficiently.
(2) CO2's Integration into Operator-Heavy Zones: CO2 safely permeates operation rooms and warehouses, ensuring the utmost safety for personnel and assets.
