When the copper tube is wrapped in water, with refrigerant flowing inside the tube, what value should K take?
Thread Content
1. The copper tubes are wrapped around the water tank; the water is in circulation, and the refrigerant flows inside these copper tubes. 2. If we want to determine the evaporation area Fm, what value should K take? 3. What is a reasonable value for the temperature difference? Assume the cooling capacity is Q = 5 KW
It seems to me like it’s the refrigerant that’s condensing – cooling water is being used to evaporate the refrigerant. What kind of refrigerant is that? It should be an immersive coil structure; I think it’s more appropriate for the cooling water to have a temperature a few degrees lower than that of the refrigerant. As for the heat transfer coefficient, it needs to be determined based on factors such as flow rate and the type of refrigerator
To be precise, it’s necessary to first determine what type of refrigerant it is. But since it’s copper tubing, it’s likely some kind of Freon, right? Looking forward to everyone’s calculations and analyses!
Thanks. The refrigerant is R22; it’s basically circulating water, with copper tubes wrapped around the water tank. The water in the cooling tank is getting cold – why isn’t there any expert to help solve this issue? It would be good to have an analysis done; could everyone learn from each other and exchange ideas?
The cooling capacity is way too low! 5KW？ The temperature difference is generally set at 5 degrees, but it should be determined based on your actual needs.
