Thermal study in simple solar still hybrid with heat pump

Finding solutions for the purification of sea water in today admits a major necessity in all countries especially the third world. The considerable increase in both the population growth of all types of industry is thought to find high quality technology to make drinking water. Two models can be used in this work: simple solar still and simple solar still coupled with heat pump. In this research, the productivity of water by SSD and SSDHP was determined by the orientation, the use of heat pump, the simple or double glass cover. The productivity can exceed 1.2L/m'h for the SSDHP and 0.5L/m'h for SSD model. The result of the global efficiency is determined for two models SSD and SSDHP gives respectively 30 %, 50 %. The internal efficiency attained 35% for SSD and 60 % of the SSDHP models. Convective heat coefficient can be determined is attained 2.5W/m

°C and 0.5 W/m

°C respectively for SSDHP and SSD models.
