Building in Nassiriah city is air conditioned with the following assumptions: Sensible heat load 46.4 kW, latent heat load 11.6 kW, outside design conditions 38 C DBT and 28 C WBT, Inside design conditions 24 C DBT and 60 % relative humidity, Infiltrated air 1200 m³/h, Apparatus dew point temperature 10 C, amount of recirculated air from the building 60%, Total mass of air entering the building 975 kg/min, The recirculated air is mixed with the conditioned air after the cooling coil. Find the following: 1-The conditions of air leaving the conditioner coil before mixing with the recirculated air. 2-The conditions of air before entering the building. 3-The mass of air entering the conditioner.
