NH3/CO2 Cascade Refrigeration System
1. Understanding the NH3/CO2 Cascade Refrigeration System
Dive into the sophisticated world of the NH3/CO2 cascade refrigeration system, a marvel of modern engineering. This system is divided into two crucial stages: the high-temperature level utilizing NH3 as the refrigerant and the low-temperature level employing CO2. The magic happens as refrigerant NH3 evaporates in the high-temperature system, effectively condensing CO2 gas from the low-temperature stage. The integration of a condensation evaporator seamlessly connects the two stages, functioning dually as the condenser for CO2 and evaporator for NH3.
The heat management within this system is an exquisite dance: heat absorbed by CO2 is transferred to the robust NH3 through the highly efficient condensing evaporator. From there, the NH3 disperses the heat into the environment via a high-temperature condenser. The journey of CO2 continues as it condenses and enters the CO2 reservoir. Following a meticulous path—passing through a dryer filter and throttle valve—it reaches the CO2 gas-liquid separator. Here, the liquid CO2 is propelled by a circulation pump to the CO2 evaporator. Post-evaporation, the transformed two-phase CO2 returns to the gas-liquid separator. The CO2 gas is then compressed once more by the compressor, repeating this seamless cycle to maintain optimal refrigeration.
In the realm of the NH3/CO2 cascade refrigeration system, high and low-temperature levels operate using singular refrigerants. The NH3 system mirrors conventional refrigeration equipment, with integral components such as a compressor, condenser, and liquid storage. Meanwhile, the CO2 system is a sophisticated assembly featuring a CO2 compressor, condensing evaporator, reservoir, and an array of separators and devices designed for ultimate efficiency and performance.
The The CO2 gas-liquid separator is a pivotal component that ensures the efficiency and reliability of the CO2 compression refrigeration system. It adeptly separates CO2 gas droplets from the evaporator, preserving compressor integrity and maintaining a stable liquid level during operation. When not in use, it can accommodate all CO2 liquid, thanks to its voluminous design. An auxiliary evaporator placed atop the separator safeguards against excessive CO2 pressure post-shutdown. In the cascade system, the condensing evaporator ingeniously serves dual roles, acting as an evaporator for NH3 and a condenser for CO2, where it facilitates the phase transition of carbon dioxide gas to liquid within its shell.
2. The Remarkable Advantages of the NH3/CO2 Cascade Refrigeration System
(1) Enhanced Safety with NH3:
(1.(1)) The NH3/CO2 cascade system significantly diminishes the condensing pressure of NH3, reducing it to approximately one-tenth of traditional ammonia systems, ensuring heightened safety.
(1.(2)) NH3 is confined within the designated machine room, akin to a 'tiger in a cage', managed by skilled personnel, ensuring controlled and safe operation.
(1.(3)) Capitalizes on the excellent heat transfer properties of NH3 within the high-temperature region, effectively cooling CO2 with precision.
(2) The strategic incorporation of CO2 enables safe integration into personnel-centric environments like operation rooms and warehouses, prioritizing safety for individuals and safeguarding assets.
