Feasibility Study of Solar Water Heater System and ‎Ambient Heating for the Laboratory Complex of ‎Ahvaz Branch of Islamic Azad University with ‎Valentin T*SOL Software

Iran is located between the orbits of 25 to 40 degrees north latitude and is located in a region that is among the highest in terms of solar energy among the parts of the world. The amount of solar radiation in Iran is estimated between 1800 to 2200 kWh per square meter per year, which is higher than the global average. In Iran, on average, more than 300 sunny days are reported annually, which is very significant. This energy can be used in different ways, such as electricity generation, heating and cooling, fresh water production, hot water supply, etc. In this paper, using T*SOL software, a solar heating system (including solar water heater, space heating) has been designed for laboratory complex No. 3 of Islamic Azad University, Ahvaz Branch and has been simulated for different time periods such as annually.
