Air from a workspace enters an air conditioner unit at 30 °C dry bulb and 25 °C wet bulb. The air leaves the air conditioner and returns to the space at 25 °C dry bulb and 6.5 °C dew point temperature. If there is any, the condensate leaves the air conditioner at the temperature of the air leaving the cooling coils. The volume flow rate of the air returned to the workspace is 1000 m3 /min. Atmospheric pressure is 1 atm. Determine: a. The heat transfer rate from the air, in kW b. The mass flow rate of the condensed water, if any, in kg/h.
