Textbook Question
Chapter 10, Problem 15RQ
A service technician is charging an air-conditioning system that has a TX V as the metering device using the subcooling method of charging. The high-side saturation temperature is 110°F and the unit's technical manual specifies 10°F of liquid subcooling. What would thedesired liquid-line temperature be at the condensing unit?
