Today, the use of solar energy is expanding and developing because this energy is easily available and there are various technologies for producing thermal and electrical energy and cooling. One of the most energy-consuming parts is heating and cooling systems in residential buildings, which includes the major part of energy consumption in buildings. Therefore, in this research, the purpose of this research is to produce thermal energy for the cooling system using solar energy, which was used

... r analysis using Trnsys software, the purpose of this simulation is to check the thermodynamic parameters of the fluid and economic analysis, taking into account biological pollutants. The environment of the system has been considered. One of the important results of this research is the return on investment of 4 years, in which the required amount of energy supply through the solar system is 0.94.
