A warehouse measures 40 feet by 50 feet and has 20-foot-high walls. Thewarehouse was built on a concrete slab and has 6 inches of insulation inthe wood frame walls and 91⁄2 inches in the ceiling. There are no windowsin the building, and the door is made just like the walls. What is the heat loadfor this warehouse in an area where there is a 75°F design temperaturedifference?

Answer ONLY items 5-8. Room dimensions are: LxWxH = 8.50 m, 5.0 m, 3m. Originally, the room had linoleum flooring with an absorption coefficient of 0.03. Two opposite walls were cladded with unglazed bricks with an absorption coefficient of 0.02, the one having the entrance gypsum door (2.1 m X 0.80 m) with 0.05 abs.co.; the other two were just bare concrete with sliding glass window openings of 1.80m x 1.20 m each; the bare concrete with an abs.co. Of 0.31 and the window glass with 0.18, the ceiling, too , had bare concrete as its finish at 500 Hz. The client would like to renovate the space into an acoustical studio room and would like to change the ceiling and the flooring. The ceiling will have a vinyl faced fiberglass panel with an abs.co. of 0.71, and the floor will have mineral fiber tiles with an abs.co. Of 0.66, all at 500 Hz.

If the room in problem 16 faced the sun, an additional cooling load would becreated. This extra cooling load would be due to the sun shining through thewindow and heating the room. A window facing south would allow a maximumof 75 Btu per hour to enter the room for each square foot of window area. Ifthe room has its window facing south, what is the maximum cooling load forthe room?

A two-story building of volume of 540 m3 has an effective air leakage area of 510 cm2. The outdoor and indoor design temperatures for winter conditions are í10°C and 20°C respectively. The average design wind speed is 7msí1. The house is sheltered by other houses across the street. Estimate (i) the air infiltration rate, and (ii) the air exchange rate per hour.
A cold-storage warehouse is to be constructed of a number of individual rooms that are maintained at various temperatures. The walls of one room are constructed of 4 inches thick masonry on the outside of 0.5 inches thick plywood on the side. Sandwiched between the masonry and plywood is glass fiber insulation that is 3.5 inches thick. The inside-wall temperature is to be maintained at −10°F and the outside-wall temperature is 70°F. As a first step in sizing the required cooling unit, determine the heat flow the wall on a per-square-foot basis.
What are the three basic directions of heat flow from warm-air furances?
