Abstract

In this paper, an analysis on the thermal energy saving in large industrial halls is performed using air solar heaters. Computations are carried out for latitudes in the range of 35^◦≤ Lat. ≤40^◦ at the fixed Longitude of 45^◦. A large industrial hall with dimensions of length=100 m, width=30 m, and 4 m ≤ height ≤ 6 m is considered to study. In addition, on the south wall of the hall 25 flat air solar heater with dimensions of length=2 m and height=3m are considered. Several results are obtained in this study. For example, thermal energy audit of the building revealed that the industrial hall located at the latitude of 40^◦ has more energy demand compared with the smaller latitudes. On the other hand, it is demonstrated that application of air solar heaters for such building saves the thermal energy consumption significantly depending on the latitude value.
