A home’s temperature is maintained at 25◦C by an AC system with a COP of 3.2 which cools outside air (38◦C with a 30°C Wet Bulb) to 10 C and injects the cooled air into the home. The 25 C air exits the home. A) draw the process on the attached psychrometric chart. B) If the home gains 50,000 KJ/hr what is the required power in kW? C) How much water is condensed if any? D) Without changing the COP or the heat gain of the home what could be done to lower the power requirement of the AC system and what is the minimum power required?
