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 TR c. The heat required in the reheater kW
Atmospheric air, which is a mixture of dry air and water vapour, is supplied into ducting with a cooling coil. Initially it has a relative humidity of 0.57, volumetric flow rate of 0.72 mis and temperature of 17°C. The atmospheric air is then passed over a cooling coil such that the temperature drops to 6°C. As this is below the dew point, the water vapour condensates after cooling coll and the air leaves in a saturated state. Assuming the barometric pressure of atmosphenic air to be 1.01325 bar, determine the folowing quantities in question parts () to (vi): (1) Partial pressure of water vapour in the air and water vapour mixture entering, Pul
