Abstract The purpose of solar systems is to store heat by building materials to provide optimal heating inside the house. The Trombe wall is one of the most cost-effective solutions for the optimal use of solar energy for building heating. For this reason, in this study, the room temperature variation (with the use of a Trombe wall) was studied with a modified thermal model and compared with experimental results. Comparison of thermal model and experimental results refers to the remarkable acceptance of the studied thermal model. Based on the results, one-hour changes (from 9 o’clock to the initial temperature of 13.7 °C for 8 h to 17 o’clock), based on solar radiation, the temperature changes in experimental and computational results have an increasing trend. Gradually at 17 o’clock, due to the decrease in the intensity of solar radiation, a temperature equilibrium is created in the room space.

Introduction The energy crisis, due to the excessive consumption of fuel, has led to appropriate solutions to energy management based on solar energy. The Trombe wall is one of the most important solutions for energy management in the building (Bojic et al. 2014; Briga-Sa et al. 2014; Jaber and Ajib 2011). Trombe wall is a solar thermal based heating system for storing heat by building materials. Also, this heating system in summer can also reduce the unpleasant heat and control the high heating phenomenon in the summer. Various factors, such as ventilator, fan, insulating and wall materials, affect the efficiency of the Trombe wall and in recent years, studies on these factors have been considered by researchers. The two vents are mounted on the top and bottom of the * Seyed Hossein Hashemi [email protected] 1

Trombe wall to help provide hot air throughout the day to heat the room. When the air is warm and lighter, it enters the room through the upper vent and through the lower vent, cold air will be replaced (Briga-Sa et al. 2014; Jaber and Ajib 2011; Rabani et al. 2015a; He et al. 2015; Okonkwo and Akubuo 2007). Due to the importance of the vent in the performance of the Trombe wall, Balcomb and McFarland (Balcomb and McFarland 1978) studied the performance of the Trombe wall despite the vent (in nine US regions. Their study showed that the Tromb wall, with a valve (under climatic conditions such as Boston), has 10–20% better performa
