EXPERIMENTAL STUDIES AND ECONOMIC CONSIDERATIONS ON A LIVING SPACE HEATED THROUGH PASSIVE SOLAR GAIN AND THROUGH ELECTRIC POWER

ABSTRACT
The Tromber wall, of an area AT = 8.8 m ,built on the southern facade of a room, heats the accommodation during the transition months, complementary to electric power. The statistical processing of the experimental data led to a global quantitative image of the wall's behavior during the average day of the months March, April, September, and October 1999. The inner climate parameters are: tint = 21 °C, trad = 17.9 °C, troom= 19.5 °C, φ = (35 -70) %, E ∈ (80 - 120) lx. The thermal comfort factor is B = -0.325. These values insure a room's comfort close to the optimal one prescribed by the hygienists. The heliothermal conversion's efficiency is ηT = 10.4 %. The proportion of heat supplied by the wall in the entire energy required by the room is η(heat) = 45.8 %. The wall's specific cost is Pu = 24.9 Euro/m . The write-off period of the initial investment is n = 53 years. The development of passive solar architecture in the Euro-region Danube-Cris-Mures-Tisa which includes the town of Timisoara (45° N, 22° E), was proven feasible by the experiments from both the energy and the economical point of view.
