Optimization of insulation thickens in a long term solar storage system
Abstract:
The effect of insulation thickness of Rockwool and Polyurethane insulators, used to insulate a long term concrete storage tank, on the total cost of a solar system used in space heating and domestic hot water systems was studied together with an economic analysis of the solar system. An optimum thickness of Rockwool or Polyurethane insulators was computed to be 16 and 8 cm respectively, under 100% solar contribution to the heating load. The study was conducted on a house with an area of 160 m2 constructed of locally available materials especially used to minimize heat losses during the heating period. It was found that using solar energy for space heating and domestic hot water systems in Jordan is very promising and has a low cost.
