Experience the cutting-edge NH3/CO2 cascade refrigeration system.
1. Understanding the NH3/CO2 Cascade Refrigeration System: A Marvel of Engineering
The NH3/CO2 cascade refrigeration system ingeniously combines two distinct thermal stages: a high-temperature stage utilizing NH3 as the refrigerant, and a low-temperature stage employing CO2. In this remarkable system, the high-temperature NH3 evaporation facilitates the condensation of CO2 refrigerant gas released from the low-temperature stage. A sophisticated condensation evaporator seamlessly joins these stages, serving dual functions as the condenser for the low temperature and the evaporator for the high temperature.
In this system, the heat load is seamlessly conveyed to the CO2 refrigerant via the end evaporator. The absorbed heat is efficiently transferred to the high-temperature NH3 refrigerant through the condensing evaporator. The NH3 refrigerant then channels this heat to the high-temperature condenser, releasing it effortlessly into the surroundings with the aid of a cooling medium. Post condensation, CO2 travels to the CO2 reservoir, then proceeds to the gas-liquid separator through a dryer filter and throttle valve. The liquid CO2 is propelled to the CO2 evaporator by the CO2 circulation pump, completing the cycle without additional cooling devices such as freezers or chillers. Following evaporation, two-phase CO2 returns to the gas-liquid separator, with gaseous CO2 being compressed by the compressor into the condensing evaporator, repeating the entire cascade cycle flawlessly.
Within the NH3/CO2 cascade refrigeration system, each temperature stage operates as an independent refrigeration system with its own refrigerant. The equipment is divided accordingly: the high-temperature NH3 system mirrors conventional refrigeration setups, complete with a compressor, condenser, liquid storage, gas-liquid separator, and throttling device. In contrast, the low temperature CO2 system boasts a CO2 compressor, condensing evaporator, reservoir, gas-liquid separator, filter dryer, pump, throttling device, evaporator, and expansion vessel, each ensuring seamless operation and efficiency.
The The CO2 gas-liquid separator plays a crucial role in the CO2 compression refrigeration system by effectively segregating droplets from the evaporator and avoiding wet strokes in the compressor. It upholds a stable liquid level during pump operation and manages liquid return when the pump halts. If the gas-liquid separator functions as a reservoir during downtime, it must accommodate the entire CO2 liquid volume. An auxiliary evaporator positioned atop the separator counteracts excessive CO2 pressure post-shutdown. In the NH3/CO2 cascade system, the condensing evaporator serves dual purposes: operating as the NH3-side evaporator and CO2-side condenser, facilitating compound liquid evaporation and CO2 gas-to-liquid condensation.
2. Unveiling the Advantages of the NH3/CO2 Cascade Refrigeration System
(1) Enhanced Safety with Reduced NH3 Risks:
(1.(1)) The NH3/CO2 cascade system significantly lowers the condensing pressure of NH3 by approximately 90%, compared to traditional ammonia systems;
(1.(2)) NH3 confinement to secure areas like machine or equipment rooms, akin to a 'tiger' safely enclosed, overseen by skilled personnel;
(1.(3)) Optimal use of NH3's excellent heat transfer properties in high-temperature zones, efficiently cooling CO2.
(2) Integrating CO2 as a Medium for Enhanced Safety in Occupied Areas: CO2 serves as the refrigerant in high-traffic zones such as operation rooms or storage warehouses, ensuring the utmost safety for personnel and property.
