The Basic Setup
Hello,
I am trying to learn the right way to create the setup for a refrigeration unit.
Supposing that we know the evaporator load, evaporation temp., condensing temp., and the
refrigerant used.
From which part should we start? Compressor, condenser, expansion valve,... etc.?
How do we make the selection for each? There are commercial softwares for compressor and
condenser selection but how the selection of expansion valve, solenoid valve, sight glass
and drier are done?
Searched the forum but could not find anything related.
Cheers

Re: The Basic Setup
You start with evaporator, then compressor than condenser. Then you select other parts.
For selection and dimensioning of other parts there is Danfoss Coolcat software.

Re: The Basic Setup
thanks nike,
i tried the coolcat. maybe because of my java settings it did not fully function. but apparently i'm not sure.
Disregarding these commercial softwares i really would like to learn the scienfic way behind it. My aim is to get the knowledge of doing these calculations on paper.
Is there a book (or e-book) that you can recommend?
