A pretty basic question about box temps here, but Ive been finding that many of the explanations given to various questions on here easily trump anything Ive found book wise from a 'user-friendly' perspective, so to speak.
If you calculate your box temp based on the PT temperature equivalent of whatever your suction line pressure is, then adding say 10* TD, then 10* for your TXV............I am under the understanding that this is the formula to get box temp from suction line pressure..........My question is related to the 10* superheat from the TXV.
I THOUGHT that I had a fairly good understanding of superheat and subcooling, but Im having a hard time around understanding what is meant by superheat at the TXV and superheat at the compressor? Is this simply the superheat that is measured at the outlet of each? If so, then I fell pretty silly for asking, but if there's more to it than this then I would love to hear some ore experienced opinions.
