A bedroom is to be conditioned that the total heat load is 20 kW and the sensible heat ratio is 0.4. The room is to be maintained at 22°C DB and 55% relative humidity. The outside air condition is at 32°C DB and 23°C WB. The conditioned ain from the reheater enters the room at 17°C. Determine the following: a. The percentage of recirculated air if the mass flow rate of water vapor in the mixture is 1 kg/min

A bedroom is to be conditioned that the total heat load is 20 kW and the sensible
heat ratio is 0.4. The room is to be maintained at 22°C DB and 55% relative
humidity. The outside air condition is at 32°C DB and 23°C WB. The conditioned air
from the reheater enters the room at 17°C. Determine the following:
a. The percentage of recirculated air if the mass flow rate of water vapor in the
mixture is 1 kg/min
b. The refrigeration load
