    Sensible Heat: Room Sensible Heat - RSH ('B' + 'C' + 'D' + 'E' + 'F' + 'G-A' + 'H')

    Uploaded by

    De Silva Shmapk
    This document summarizes a cooling load calculation for a building. It lists outdoor and indoor design conditions of 33.9°C and 29.2°C wet bulb temperatures outdoors and 24°C and 18.2°C indoors. It then calculates sensible and latent heat gains from various building elements and internal loads. Sensible heat gains included the roof, walls, glass conduction and solar gain, partitions, and lights. Total sensible heat was calculated to be 46,871.48W. Latent heat gain from ventilation was calculated to be 4,870.80W based on an assumed air change rate. The total cooling load was calculated to be 51,742.28W.
