The room sensible and latent heat loads, for an air conditioned space are 25 kW and 7.5 kW respectively. The room condition is 26 C dry bulb temperature and 50% relative humidity. The outdoor condition is 40 C dry bulb temperature and 50% relative humidity. The ventilation requirement is such that on mass flow rate basis 25% of fresh air is introduced and 75% of supply ait is recirculated. The by-pass factor of the cooling coil is 0.15. Determine i) Supply air flow rate ii) Outside air sensible heat iii) Outside air latent heat and iv) Grand total heat.
