Study of Transient Simulation for Solar Heating System


In the current study simulation method was used for design of solar waterheating system. An integrated transient simulation program was built up forsimulating the Iraqi solar house heating system using TRNSYS as a design tool.The modeling was carried out is modeled for other virtual solar heating systemssimilar to the Iraqi solar house. The results obtained were used to develop ageneral design procedure for solar heating systems in Baghdad.Using the design charts and TRNSYS as a design tool simplifies the designer’stask for predicting the long - term heating energy supplied from a solar collectorarray.The above simulation was applied for Iraqi solar house and the results gave theincreasing in storage volume caused increase the auxiliary energy supplied to thesystem. So, the best practical storage volume is 20m3 and increasing the collectorarea to optimum value results in increasing the solar fraction (f). The solar fractionmay reach 0.97 when the collector area becomes as 400m2 at storage volume of20m
