Discover the state-of-the-art NH3/CO2 cascade refrigeration system, engineered for superior performance.
1. Unveiling the NH3/CO2 Cascade Refrigeration System Principles
The NH3/CO2 cascade refrigeration system is an innovative solution composed of a high-temperature stage using NH3 as the refrigerant and a low-temperature stage utilizing CO2. The high-temperature NH3 evaporates to condense the CO2 refrigerant from the low-temperature stage. A singular condensation-evaporator bridge connects these dual stages, acting as both the condenser for the CO2 and the evaporator for NH3, enabling seamless heat transfer.
The heat load is efficiently transferred to the CO2 refrigerant through the end evaporator. This absorbed heat is passed on to the high-temperature NH3 refrigerant via the condensing evaporator, which then releases it into the environment through a high-temperature condenser aided by a cooling medium. The condensed CO2 journey continues as it enters the CO2 reservoir, flowing through the dryer filter, throttle valve, and gas-liquid separator. The CO2 circulates to the evaporator via a pump, completing its role in the cascade refrigeration cycle, ensuring effective thermal management.
Within the NH3/CO2 cascade refrigeration system, the high and low temperature levels operate independently with single refrigerants. The high-temperature NH3 system mirrors conventional refrigeration systems, incorporating a refrigeration compressor, condenser, liquid storage, and more. The low-temperature CO2 system is comprised of essential components including a CO2 compressor, condensing evaporator, reservoir, and auxiliary elements, all designed for optimal performance and efficiency.
The The CO2 gas-liquid separator plays a crucial role by separating liquid droplets from the CO2 gas, preventing compressor wet strokes, maintaining liquid stability during pump operations, and storing returning liquids when the pump halts. It doubles as a CO2 reservoir, capable of containing the entire system's CO2 liquid. Additionally, an auxiliary evaporator is fitted to prevent excessive pressure post-shutdown. The condensing evaporator, integral to the NH3/CO2 system, functions dually, enabling compound fluid to evaporate and absorb heat while condensing CO2 gas into liquid form.
2. Key Advantages of the NH3/CO2 Cascade Refrigeration System
(1) Enhanced Safety with Reduced NH3 Risks:
(1.(1)) This innovative NH3/CO2 cascade refrigeration system dramatically lowers the condensing pressure of NH3, reducing its charge to approximately 1/10 of conventional systems.
(1.(2)) NH3 remains confined to controlled environments like machine and equipment rooms, akin to a 'tiger in a cage,' overseen by skilled professionals.
(1.(3)) The system leverages NH3's excellent heat transfer properties in high-temperature regions to effectively cool CO2.
(2) CO2 safely enters personnel-dense areas like operation rooms and warehouses, ensuring the utmost safety for personnel and assets.
