The purpose of this project was to design a heating system for a building with a combination of solar collectors and a boiler. For the heating of this building it was decided to use a floor heating system.
First, with the help of the architectural drawings of the building, the heating requirements for space heating and hot water services for the building were calculated. From these calculations it seems that the total heat load is 19 KW.
After that, a suitable system for the collection and storage of low temperature solar energy was designed to satisfy the heat requirements of the building. Here the F -CHART software was needed to calculate the optimum numbers of solar collectors with the maximum life savings and the best fraction of the load F, which was found 28 collectors. But in this project a combination of series and parallel arrangement (reverse – return) of 30 collectors will be used with five rows (see Appendix I), which will cover only the 66% of the total heat requirements.
In the next step, with the help of a second computer program the calculations for the floor heating system were performed as shown in Appendix G. From these calculations it appears that the system should include feeding 7 loops and another one feeding 6 loops.
Then the optimum size of the solar collector, the floor heating pipes, storage unit, pumps, piping and other equipment and accessories involved in the system were determined, including all necessary instrumentation and controls.
After that, the detail drawings showing the installation of solar collectors, the piping installation of floor heating system, and the diagrammatic layout of the heating installations is performed.
Finally, based on the calculations and design configuration selected as well as the pipe sizing and equipment selection done, a cost analysis was performed for a floor heating system with solar panels and it was compared with a floor heating without solar panels.
In the first case the cost is estimated approximately up to £12450 while the second it will approximately be £3900.
