May I ask, when using circulating cooling water to cool the liquid in a gas, to what lowest temperature can it be condensed? ? The temperature that is more economical for engineering purposes
The economic temperature difference is taken as a minimum of 5 degrees; for example, if the temperature of the water supplied for circulation is 28 degrees, then the lowest temperature to which the process medium can be cooled is considered to be 33 degrees

I’ll give you a calculation to look at tomorrow – the areas corresponding to a temperature difference of 10 degrees, 5 degrees, and 1 degree – and then you’ll know how to choose.
It mainly depends here on the temperature of the circulating cooling water, which in turn is determined by the local temperature and relative humidity. The other option is what you mentioned, namely “engineered for economic efficiency”; in theory, it’s possible to cool it down to a temperature close to that of the cooling water. But that’s no longer what constitutes “engineered for economic efficiency”. Therefore, considering a temperature 4 to 5 degrees higher than that of the cooling water is feasible.
