This dissertation was written as a part of the MSc in Energy Systems at the
International Hellenic University. It deals with the analysis of the operation of flat plate
solar collectors which leads to the numerical simulation of their performance.
Solar collectors are a widespread means of exploiting solar energy. They are special
kinds of heat exchangers that transform solar radiation energy to internal energy of
the transport medium. There are different kinds of solar collectors which can be
distinguished by their concentration or not, the type of heat transfer liquid used, the
temperature range of the working fluid, their and whether they are covered or
uncovered.
The evaluation of collector performance requires the calculation of the absorbed
solar radiation and the heat loss to the surroundings. The equations describing these
variables are developed in detail in this dissertation and they constitute the model for
the collector numerical simulation.
I would like to thank Dr. Georgios Martinopoulos for his concern and advice which
helped me accomplish this dissertation.
