The conditioning plant of a room consists of a fresh air intake, a cooling coil- followed by a mixing chamber for the cooled fresh air and recirculated room air, and a supply fan. The cooling coil handles all fresh air and has a BPF of 0.1. The ratio of fresh air to recirculated air is determined by modulating dampers. The other data is as follows: Inside conditions: DBT = 24 C, RH = 50% Outside conditions: DBT = 30 C, WBT = 23.3 C Heat gains: Supply air quantity: 191 cmm Neglecting temperature changes in the fan and duct, determine: DBT and moisture content of supply air ii. RSH = 14.7 kW, RLH = 3kW i. Mass flow rate of moist air supplied to room DBT and moisture content of air leaving cooling coil Load on the cooling coil Note: Use psychrometric chart. iii. iv.
