EXPERIMENTAL STUDY OF A SOLAR STILL ACTIVED BY A HEAT PUMP | Journal of Global Ecology and Envi....

This project is about a second solar prototype that is still combined with a heat pump HP. It is distinguished by a barrier separating the HP's steam generating section from the evaporator compartment (where the condensate is collected).

The test results show three different HP configurations depending on whether the distiller is fixed to the south or constantly oriented to the sun, and whether it is positioned in the sun (outside) or inside (no sun). The water temperatures at the condenser, the wet and ambient air, and the relative humidity are all measured. The distillate flow is also measured, and the HP's energy efficiency and coefficient of performance (COP) are assessed. When the sun's and cap's effects combine to heat the water and subsequently distil it, we find that the sun provides 2/3 due to the HP and the remaining 1/3 owing to the cap. The warm-up and thus evaporation of water in the sun is higher than simply heating the HP's condenser, resulting in a bigger flow of distillate.
