Product Description

NH3/CO2 Cascade Refrigeration System
1. The Principle of NH3/CO2 Cascade Refrigeration System
Experience the brilliance of the NH3/CO2 cascade refrigeration system, meticulously designed with two distinct parts: the high-temperature stage and the low-temperature stage. In this innovative setup, NH3 takes the spotlight as the refrigerant in the high-temperature stage, while CO2 dazzles as the refrigerant in the low-temperature stage. Witness the marvel as the evaporation of NH3 in the high temperature system condenses the CO2 gas from the low temperature stage. A masterpiece of engineering, the condensation evaporator seamlessly connects the high and low temperature levels, serving dual roles as the condenser for the low temperature stage and the evaporator for the high temperature stage.

In a symphony of thermal dynamics, the heat load is beautifully transferred to the CO2 refrigerant via the end evaporator, with the CO2 refrigerant's absorbed heat cascading to the high-temperature NH3 refrigerant through the condensing evaporator. This NH3 refrigerant then gracefully transfers the amassed heat to the high-temperature condenser, releasing it effortlessly to the environment through an efficient cooling medium. The condensed CO2, having completed its journey in the condensing evaporator, proceeds to the CO2 reservoir, eventually making its way to the CO2 gas-liquid separator through a dryer filter and throttle valve. Liquid CO2 embarks on its mission to the CO2 evaporator, propelled by the CO2 circulation pump, sans any end cooling device. As it exits the evaporator, the CO2 returns in a two-phase state to the gas-liquid separator, where the gaseous CO2 is gently guided by the compressor, compressed into the condensing evaporator. This continuous cycle culminates the sophisticated cascade refrigeration process.

In the realm of NH3/CO2 cascade refrigeration, the intricate balance between high and low temperature levels is orchestrated by systems using singular refrigerants. The high-temperature NH3 refrigeration system mirrors conventional systems, encompassing the essential refrigeration compressor, condenser, liquid storage, gas-liquid separator, and throttling device. Meanwhile, the low-temperature CO2 system impresses with its CO2 compressor, condensing evaporator, reservoir, gas-liquid separator, filter dryer, pump, throttling device, evaporator, and expansion vessel, each contributing to the seamless operation of the system.

The The CO2 gas-liquid separator is a pivotal component, expertly designed to separate CO2 gas droplets from the evaporator within the CO2 compression refrigeration system, preventing compressor wet strokes and maintaining a stable liquid level during pump operation. It also adeptly stores liquid return from end equipment and pipelines when the pump ceases operation. When utilized as a CO2 reservoir when inactive, its volume adeptly accommodates all system CO2 liquid. Furthermore, an auxiliary evaporator is strategically placed atop the gas-liquid separator to prevent excessive CO2 pressure post-shutdown. Within the NH3/CO2 cascade refrigeration system, the condensing evaporator performs dual roles, acting as the NH3 side evaporator and CO2 side condenser, facilitating compound liquid evaporation and heat absorption within the tube, while the shell witnesses the transformation of carbon dioxide gas into a liquid state.

2. Advantages of NH3/CO2 Cascade Refrigeration System
(1) Minimized NH3 Safety Concerns:
(1.(1)) The NH3/CO2 cascade refrigeration system ingeniously minimizes NH3 condensing pressure, substituting the traditional ammonia refrigeration system charge with just 1/10 of its original force, ensuring safer operations.
(1.(2)) NH3 is securely confined to the machine room, akin to a 'tiger in a cage,' under the watchful eye of skilled professionals, ensuring safety and precision.
(1.(3)) By harnessing NH3's exceptional heat transfer qualities in high-temperature regions, the system efficiently cools CO2, exemplifying superior engineering.
(2) CO2 as an Ideal Medium: CO2 effortlessly integrates into personnel-intensive environments, such as single-freezing machines and warehouses, safeguarding both personnel and property with its reliability and safety.
