EXPERIMENTAL DATA PROCESSING IN A SOLAR HEATING SYSTEM

摘要

In the paper is presented the mode of processing the results of an experimental study done upon a solar thermal system, destined to heat water, functioning in Arad (lat. 46.19°N; long. 21.31°E), in the period December 2006-July 2008. The study is based on a research done in the European projects: FP6 GREENENERGY (2005-2007): 'Energy optimisation in European greenhouses' and B.EN.A. - COSMOTE (2007): 'Remote computer assisted command and optimisation of the use of a solar installation for greenhouses and small consumers'. The processed experimental data are: the thermal agent temperature at the exit of solar collectors T_2, the temperature of hot water in the tank T_1 and illumination E. The data were processed with MathCAD software, version 13, by defining a series of functions, and variation graphics of the monitorised parametres were obtained, according to time, for the west location of Romania.
