(11) An air-conditioning system is to be designed for a restaurant with the following data: Outside design conditions = 40°C DBT, 28°C WBT Inside design conditions = 25°C DBT, 50% RH Solar heat gain through walls, roofs and floor = 5.87 kW Solar heat gain through glass = 5.52 kW Number of Occupants = 25 Sensible heat gain per person = 58 W Latent heat gain per person = 58 W Internal lighting load = Lamps of 100W and Florescent tubes of 80 W Sensible heat gain from other recourses = 11.63 kW Infiltrated air = 15m3/min Bypass factor = 0.2 Apparent dew point temperature of the cooling coil = 10.8º. If 25% of fresh air and 75% of recirculated air is mixed and passed through the conditioner coil, Determine: () The Sensible heat gain of the room (ii) Room sensible heat factor The amount of total air required (iv) The capacity of the air-conditioning plant 2 State 1 DBT = 40°C WBT = 28°C State 2 Room DBT=25°C RH = 50% 3 = Mixing Cooling Coil
