DESIGN PROBLEM Design a hot water heating system for the shown residence which is located in the city of Amman. The following data are given: T. -5 °C, 6. = 70%, T, = 22 °C, 9 = 50%, wind speed = 8 m/s, ceiling height = 3.0 m. The wall, ceiling and floor constructions are as follows: (a) Wall construction: (1) Hard stone, Ar = 70 mm, k=2.2 W/m°C. (2) Concrete, Ar= 200 mm, k=1.7 W/m°C. (3) Polystyrene, Ar=25 mm, k=0.034 W/m°C. (4) Hollow cement brick, Ar=100 mm, k = 0.95 W/m°C. (5) Plaster, Ar=25 mm, k=1,2 W/m-°C. (b) Ceiling construction: (1) Plaster, Ar=25 mm, k=1,2 W/m°C. (2) Hollow brick, Ar=180 mm, *=0.95 W/m°C. (3) Reinforced concrete, Ar=00 mm, k = 1.75 W/m°C. (4) Polystyrene insulation, Ar=25 mm, k = 0.034 W/m°C. (5) Concrete, Ar=00 mm, k= 1.75 W/m°C. (6) Asphalt mix, Ax =20 mm, k = 0.71 W/m°C. () Partition construction: (1) Plaster, Ar=25 mm, k = 1.2 W/m°C. (2) Cement brick, Ax =150 mm, k = 0.95 W/m-°C. (3) Plaster, Ar=25 mm, k = 1.2 W/m °C. (d) Floor construction: (1) Terrazo (cement) tiles, Ar=50 mm, k = 1.1 W/m°C. (2) Mortar, Ar = 50 mm, k = 0.16 W/m°C. (3) Aggregates, Ar=150 mm, k = 1.05 W/m°C. (4) Stones, Ar = 250 mm, k=1.4 W/m°C.
