There are some elements that are the basis of most solar heating of water: the sensor (s), storage tank, heat transfer medium and interconnecting tubes. The hybrid solar collector PVT captures sunlight and converts it into heat which is transferred to the storage tank by means of a fluid such as water or air. An expansion vessel is used in closed to(More)
The hybrid photovoltaic thermal solar collector (PV/T) offer an interesting alternative to photovoltaic and thermal collectors installed separately, because the absorbed solar radiation is converted into heat and electricity. In this paper a new configuration of hybrid solar thermal collector is designed. We began measuring temperature, electrical power and(More)
The inhibitory effect of Mentha pulegium extract (MPE) on steel corrosion in 1 M HCl solution was investigated using potentiodynamic polarisation and electrochemical impedance spectroscopy. The inhibition efficiency of MPE was found to increase with the concentration and reached 88% at 33% (v/v). Polarisation measurements show that the natural extract acted(More)
