Qn.2. Cooling load calculations The floor plan of a mid-floor classroom in a multi-floor university building located at 40 "N latitude is shown below. It has a room dimensions of length = 10 m, width = 8 m, and a ceiling height of 3 m. It has only one east facing exterior wall and is mounted with 3 double glass windows with 13 mm air spacing and no externalinternal shading. The exterior wall is made of 200 mm concrete block with interior and exterior finish. The dimensions of the glass windows are shown below. In this example, assume there are no heat gains across the ceiling, floor nor corridor. The adjoining two classrooms do not have any class throughout the day, so the air-conditioning systems in these two rooms are switched off and their temperatures are measured to be 33 C. The classroom room has tile (vinyl) floor covering and gypsum partition. Calculate the sensible, latent and total cooling loads of the classroom at 11:00 am on 21 July, from the following information. Adjoining classroom Classroom 3.0 m Ceiling 8.0 Adjoining classroom All dimensions in meters unless otherwise specified U-value for exterior wall : 0.4 Wim'K U-value for partition wall : 1.8 W/m K U-value for glass : 3.0 W/m K 1.2 x 1.5 1.2 x 1.5 1.2 x 1.5 10.0 1.0 x 1.2 1.0 x 1.2 1.0 x 1.2 Corridor
