Desalination by Simple Solar Distiller Assisted by a Heat Pump

The increase in the population of Tunisia and the industrial development posed with acuity during the end of the major problems. Without contribution of additional resources, water will then be likely to be done increasingly rare. The solar still is a small production system, yielding on average 2-5 L/day. In this study we propose a solar distiller assisted by a heat pump. The design of this distiller uses for the evaporation of water and its condensation two phenomena are studied Simple Solar Distiller （SSD） and Simple Solar Still Distiller Hybrid with heat Pump （SSDHP）. The performance is less than 2 L/mVday and a performance of 30% for the SSD. But the SSDHP is 12 L/m2/day, the energetic efficiency reaches 90%.
