Definitions

  • the sun is the origin of most of the energy sources that we use.
  • the sun powers the cycle of water so that we may e.g. produce electricity by means of flowing water.
  • Solar energy is also stored in green plants, coal, oil and gas. It has been calculated that the solar energy falling on the earth provides approximately 15 000 times more than what we consume in the world today.
  • solar energy is mostly meant the utilization of the direct incident radiation from the sun. In Sweden the incident radiation of solar energy is between 700-1100 kWh per m and year. In many parts of the world the incident amount of energy is much larger.
  • the incident radiation from the sun may be used to generate heat and electricity. This is done with minimum environmental impact and in certain areas with an outstanding economy. Since a solar energy facility practically does not need to take any operational cost into consideration the price of energy is determined by the cost of capital. Unlike other kinds of energy the solar energy only has a fixed cost during the write-off time period.
  • Solar collectors for producing heat and hot-water are particularly interesting in places where the energy demands match the available solar incident radiation. Buildings and facilities requiring hot-water during the summer are excellent fields of application. Solar heat is especially interesting if it is combined with biofuels. In such cases nearly 100 percent renewable heat supply is achieved and the solar heat may provide the supply of heat during the summer when the biofuel facility has lower performance. The interest for the renewable energy types has increased very much since the early 90ies and renewable energy is presently the market having the greatest growth. Another important success factor specifically for the solar energy is that the sun is our cleanest energy source. With the increasing environmental problems and energy prices solar energy becomes more and more important for private house owners as well as for municipal and private property managers and energy companies.
  • a further object of the invention is to suggest a solar heat system that is improved both with regard to costs and to efficiency.
  • a further object of the invention is to suggest an improved solar collector that is adapted for use in the system of the invention and for contributing to the advantages thereof.
  • the invention generally relates to utilizing solar energy that irradiates on a solar collector unit where irradiated energy is taken up by a heat absorber that in turn heats a heat transfer medium circulating in a primary collector circuit. Heat is transferred from the heat transfer medium to a working medium in a secondary circuit.
  • a basic idea of the invention is to circulate the heat transfer medium in a closed circuit entirely within the solar collector unit and to circulate the working medium entirely separated from the collector unit. Heat energy is transferred through heat conduction from the heat transfer medium and to the working medium at a thermal interface at the collector unit.
  • the energy collected by the collector is optimally utilized through heat exchange to the working medium directly at the collecting point, which simultaneously creates conditions for a flexible collector system of a modular type.
