Abstract
Today, the use of solar energy is one of the ways to reduce the energy consumption of buildings. One of the practical methods in this field is the use of Trombe walls. The purpose of this research is to determine the solution to improve the thermal performance of Trombe wall, the thermal comfort of the interior of the building and reduce the cooling and heating load in all seasons, using phase change materials. The method of carrying out this quasi-experimental research using the simulation of a real project, in the Design Builder software environment, on two types of traditional trombe walls and with phase change materials, has been a real example in a cold and dry climate. From the investigations, it can be seen that a 30 cm thick concrete wall with a thermal resistance of 0.65 with a delay time of 7 hours and 12 minutes is the best type of traditional trombe wall; which reduces the consumption of heating, cooling and primary energy by about 20, 14 and 8 percent, respectively. In the combined Trombe wall, the amount of heating, cooling and primary energy can be reduced by 51, 11 and 15%, respectively, with phase change materials. This result points to the high efficiency of phase change materials in the thrombus wall in reducing the heating load. The use of phase change materials can improve the thermal comfort of the interior of the building and reduce energy consumption compared to the traditional trombe wall all year round.
