In recent years, the crisis of energy is growing seriously and also the contamination of ecology has been reverberated as international problem. The social concerns on energy crisis have been growing for the last several years and also the interests in new and renewable energy have been increased. Therefore, in order to solving these problems, this study has dealt with the solar air collector with perforated endothermic panel to increase the indoor temperature. And also, the PV panel for

... indoor air circulating fan has used to increase the convective heat transfer. This study is consisted with experiment and numerical parts. From this study, the experimently result is indicated that the inlet air temperature is increased up to 45 [℃]. This temperature is enough to heat the indoor air during winter season. And the numerical calculation results revealed that the mixing effect of convection is increased with increasing in fan circulating power.
