refrigerant pipe installation practice
Hi guys,
I still don't get it why we don't insulate liquid lines in split a/c application. Is this has something to do with subcooling?
According to my analysis, since liquid is formed through heat rejection in the condenser, it will have a tendency of removing more heat while it is exposed to ambient till it reaches to the evaporator unit.
In that case what if the ambient is too hot? boiling temperature of a R407c is -42 degC.
I really don't have a clear explanation on this. So if someone out there can explain it well, I would appreciate.
