Secondly, you should think of the evaporator as a heat exchanger that is designed to operate with as little refrigerant pressure drop as practical. This means that in an evaporator, refrigerant goes in mostly as liquid and “evaporates” from liquid to gas at essentially (plus or minus) one pressure and thus one temperature. As long as there is a mixture of refrigerant liquid and gas present, the temperature won’t be significantly different. It’s only after all liquid has evaporated that the remaining refrigerant gas will warm quickly and not cool as much.

what I post was the reference to ac/heat pump...just a reverse of the process..so the same unit will cool … or heat when it's 120 deg ambient, it will work way more efficient in heat mode..right?..
