I would like to ask the experts here whether this is feasible; thank you.
Why make it so complicated? An industrial air conditioner will do. There are machines that deliver cold air directly, as well as eco-friendly air conditioners that use refrigerators to cool water, which is then sent to the location through pipes
This is the process for underground ventilation in industrial and mining enterprises, right? Otherwise, the range of variations in the cooling load wouldn’t be so large. So there’s nothing wrong with your process; however, at present there are no parameters regarding the CO2 recycling circuit, and it’s necessary to determine the intake pressure, temperature, evaporation pressure, and temperature, among other things
Your analysis is absolutely correct; I do use it for ventilation in coal mining operations. How exactly should these parameters be determined? What sources should I refer to?
1. First, determine the air volume and the temperatures of the incoming and outgoing air, so as to determine the load on the evaporator； 2. By determining the temperature and vaporization pressure of liquid CO2, it is possible to determine the size of the evaporator and the amount of CO2 to be circulated ； 3. The compressor suction pressure and suction volume can be determined based on the CO2 amount and evaporation pressure ； 4. The temperature of liquid CO2 can be used to infer the load on the condenser and the exhaust pressure of the compressor ； 5. Once the suction and discharge pressures are known, it is possible to calculate the pressure ratio as well as the compressor’s load. It’s best to consult those who work on industrial air conditioning systems, as they have extensive experience in this area
