Effects of SSD and SSDHP on convective heat transfer coefficient and yields

The present study is focused on the analysis of a Simple Solar Distiller (SSD) and a Simple Solar Distiller Hybrid with Heat Pump (SSDHP) plants. Experiments have been conducted for 17 h as True Solar Time (TST) for climatic conditions of Gabès (southeast region of Tunisia), during the months of June and July 2006 for four configurations of the above-mentioned plants. Data obtained from experimental conditions are used to determine values of convective and evaporative heat transfer coefficients as well as experimental and theoretical yields. It was found that the SSDHP configuration exhibits better results than the SSD one. In this case, the convective heat transfer coefficient is found equal to 2.373 W/m2 °C and the experimental yield is equal to 1.8 l/m2 h.
