COP and Superheat - does is it help?

[mad fridgie]

Mad - The whole idea to set the dT to 1C is make sure excessive SH cannot be added as seems to be the case in Coolpack.

I do not know what the other programs predict but as DesA is in charge of the comparisons we shall see.

Your idea of a 50C liquid to be cooled in a counterflow exchanger is a bit outside the realm of the discussion at the moment but may be relavanrt later. The same rules will apply when this is analysed I suppose but is it realistic.

Just want to look at stuff you can but of the shelf.

But in coolpack, you should split the superheat between useful and non useful. So in your example you can only have 1K useful and 2K non useful. (increasing to 7K non useful)

So increase the system superheat, then you must say it is the non useful superheat that has to increase. (exclude the S/L heat exchanger)
