A space of (8 × 5 × 4) m in size occupied by a 25-person lies in the south of Iraq. The outside conditions are 5°C DBT and 85% RH. The inside design conditions are 24 °C (DBT) and 50% RH. The space has a window of (4 × 2) m and a door of (1.25 x 2.5) m. Neglect heat loss from the door, and calculate the heating load of the space and the coil heating capacity. Is the vapor condense on the inside surface of the walls, roof, and glass? Wall and roof thickness=25cm Wall and roof thermal conductivity=1 W/m² °C Glass thickness and thermal conductivity are 4mm and 1.5 W/m² °C respectively. (door) 2
