Question
A computer room located on the second floor of a five-storey office building is 10 m x 7 m. The exterior
wall is 3.5 m high and 10 m long; it is a metal curtain wall (steel backed with 10 mm of insulating
board), 75 mm of glass fiber insulation, and 16 mm of gypsum board. A double-glazed window make
up 30% of the exterior wall. The indoor temperature is 20 Celsius. calculate the cooling load at 8pm
with calculation safety factor of 1.25.
Details about appliances and lightings:
Computer: 200 watts, 5numbers, operating 8hrs every day
Lights: 8 numbers fluorescent light, 30 watts each, assume opened from 4pm to 8am every-day.
