Superheat reference
Hi there,
A normal superheat at the evaporator outlet should be between 5 to 10K. Lower than 5K would result in liquid flood-back and higher value will overload the compressor and lowers the refrigeration capacity.
I need a reliable reference for these values. I searched ASHRAE and many other references but not luck.
Does anyone know a reference?
Appreciate your help.
Cheers

Re: Superheat reference
Lana,
Please find some links, hopefully useful, but somehow think not.
Can depend on what type of TX valve, as electronic very accurate.
Also could not find article about superheat cannot be higher at evaporator outlet than air on temperature/ SST

Re: Superheat reference
Thanks for the replies.
I don't have a problem in keeping the superheat in a normal range. For some refrigerants like R290 we need at least 20K and ....
I just need a reference where this range is mentioned.
Thanks again.Even Einstein Asked Questions
