Abstract:
In Serbia, it is usually to use electricity for domestic hot water (DHW) heating. As about 70% of electrical energy is produced by using coal, with high greenhouse emission, it is beneficial to environment to use solar energy for DHW heating in solar DHW system (SDHWS). This paper represents the optimization of design, implementation in practice and operation of the solar collectors in space and time, as elements of solar installations, in order to determine the feasibility of the proposed concept modern methods of energy monitoring and energy diagnostics. These investigations use computer software EnergyPlus. The used weather data are from the meteorological station. In this paper, a use of Hooke-Jeeves algorithm is reported to obtain the maximum amounts of performances for different SDHWS use as a function of number of optimum positions of the solar collector in SDHWS during year for Belgrade, Serbia. Solar energy systems have been improved, whereby we obtain minimum consumption of fossil energy, reduction of the use of energy resources, maximizing energy security, as well as the minimum impact on the environment.
