4. A. Calculate the cooling load at 14 pm through the wall and window described by the data and assumptions below DBTi=25°C RHI-60%, DBTo= 42.5 °C WBT0=23.8°C Daily range DR-9.7°C The wall area is 2.7 m by 2.4 m (including the window area). The window area is 2.5 m² Wall number: 5 Orientation: South Take the CLTDwindow@14pm=7 ° Uwall 0.8 W/m C Uwindow 3 W/m C. B--Calculate the sensible and latent heat gains due to infiltration using the data and assumptions below. The Air Change per Hour ACH is 0.4 [1/h]. The room is 12 m long, 5 m wide and 4 m high. C-Calculate the sensible heat gains due to people and equipment using the data and assumptions below. The office working hours are 8 am to 8 pm Gain/person: 60 watts Zone: A Solar Time: 3 pm Gain/computer: 40 watts [20]
