High Efficiency Domestic Hot Water System Powered by Solar Energy
The aim of this paper is to examine the effect of solar collectors’ area, domestic hot water (DHW) storage volume and DHW consumption on the work performance of DHW system powered by solar energy. All of the considered systems incorporate flat plate solar collectors with biaxial solar tracking, DHW storage tank, circulation pump and system controller. The values of studied parameters for different cases were generated with the orthogonal array design of experiments whereupon the simulations of different DHW systems were performed in TRNSYS software. Simulation results were used for response surface optimization [1] with the aim to maximize solar gains during winter but maintain water temperatures in system below 95 °C during summer. The three-variable regression function which describes the effect of storage tank volume, DHW consumption and solar collectors’ area on the maximum useful solar energy gain to energy provided by auxiliary heater ratio is obtained. Results of the optimization are optimal storage tank volume, DHW consumption and solar collectors’ area with respect to the maximum useful solar energy gain to energy provided by auxiliary heater ratio.
