Liquid Line Temperature
The absolute highest temperature that the liquid line could be is the CTOA, and the lowest it could be is the outdoor ambient temperature. To find out what our liquid line temperature should be, we also have to look at our subcooling. You can subtract the subcooling from the CTOA to get your ideal liquid line temperature. Of course, there is ...
