Is Mean Temp in 2 phase Heat Exchangers Higher Than Logarithmic Mean?
I am looking at this paper:
https://docs.lib.purdue.edu/cgi/viewcontent.cgi?article=1314&context=iracc
Having a bit of trouble understanding all of it, but my basic question is just:
If I have a heat pump where the hot side heat exchanger has a gas-liquid phase transition, can the average temperature of the heat exchanger ever be higher than its logarithmic mean temperature?
If we need specific temperatures, suppose the inlet of the heat exchanger is 1000C gas and the outlet is condensed fluid 12C…
