A procedure for assessing the techno-economic viability of solar thermal systems in a dynamic economic environment is developed. It is shown analytically that the period for replacement of these systems depends upon the nature of their use. While determining investment viability, it is...

Uncertainties in local solar radiation, ambient temperature and thermal load data have been one of the major factors limiting the reliability and efficiency of solar thermal hybrid systems. In the present paper, moving average auto regressive exogenous (ARX) model based reasoning has been mooted...

A wind driven aspirator was integrated with a solar distillation system to produce a regenerative effect. The system is analysed on the basis of energy balance for its different components. Analytical expressions are derived for water and glass temperatures, daily yield and thermal efficiency as...

Tools available for energy conservation in buildings still lack practical and cost-effective fault detection and diagnosis technique. This paper puts forth model based fault detection technique for off-line analysis based upon Autoregressive Exogenous method. Real time operation data of a...
