(*) Volumetric heat load "F": 15 - 25 - 40 W/m
Height of volume to be cooled = 3 m
Δt = internal and external temperature difference (internal T = 26 °C, external T = + 34°C)
F1 = 15 W/m buildings with an excellent insulation level and excellent solar radiation protection
3
F2 = 25 W/m
buildings with a good insulation level and good solar radiation protection
3
F3 = 40 W/m
buildings with a scarce insulation level and scarce solar radiation protection
