You are charged with specifying a cooling system for a house. The solar and internal gains have been calculated already, but you need to increase its capacity to account for ventilation. The ventilation system will constantly exhaust 200 cubic feet per minute (CFM) of stale air and replace it with 200 21 CFM of fresh air. On a design day, the outdoor air is 90°F dry bulb temperature and 73°F wet bulb temperature. Indoor air is expected to resolve to "standard 21 air" at 75°F and 50% relative humidity (%RH). What is the additional amount of coolir acity required to account for the ventilation system? Your answer should be in Btu/h. Answer:
