One particular zone served by a multizone air handler has a design cooling load of 1750 Btu/hr (0.5 kW) with a SHF of 0.8. The coil has air entering at 84 F (29 C) db and 70 F (21 C) wb with air leaving at 50 F (10 C) db and 90% relative humidity (RH). Zone conditions are 75 F (24 C) db and 50% RH. (a) What amount of air must be supplied to the space? (b) At what condition is the air supplied to the space? (c) How much air flows over the coil and how much air bypasses the coil for this one zone? Assume sea-level pressure.
