i have recently started working as a helper in hvac. my supervisor cannot explain to me questions i have. whether or not he actually knows the answer.
with that said i have a million and one questions.....
what should the pressure differential be between low & high lines to ensure optimum efficiency? and does that change when a hp reverses?
these guys (my employers) build custom equip. and act like every question i have is a threat to some secret they dont want to share.
tired of being in the dark, thanks
