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