    The aim of this present study was to verify the reliability of the simulation model of the ground source heat pump, for this purpose a TRNSYS model has been built for a GSHP coupled with horizontal ground heat exchanger (HGHX) used for cooling a demonstration unit equipped with radiant floor located at the Research Center and Technologies of Energy (CRTEn), Tunisia and a good agreement was obtained between the simulation and experimental results. After the thermal modeling of GSHP including HGHX which were done using TRNSYS software, the optimum design parameters of the system for the severe hot zone were estimated subject to a list of economic constraints.The results obtained from this study demonstrate that the utilization of ground source heat pump is a promising and profitable solution for the cooling in the Southern climate; it is possible to lower the mean indoor air temperature below 26 °C and raise the average relative humidity to reach 65%.

    The Single Basin Solar Still Productivity Enhancement Using Flat-Plate Collector
    (Universty of El-oued جامعة الوادي, 2019-02-24) Ridha CHERRAYE; Bachir BOUCHEKIMA
    In this experimental study, single basin solar still (SBSS) has a low productivity, to solve this problem some techniques have been used, these techniques consist of using a flat plate collector. The main objective of this research was to effectively utilizing the flat plate collector (FPC) for solar still productivity enhancement and it is working as a hybrid system. The flat plat collector (FPC) model solar water heater was coupled with a solar still, and the experiments were repeated in 3 to 5 winter days, and the results were measured in the same manner for each day. The results revealed that the productivity of the still was increased 87% when it was coupled with one and was decreased 20% and 50% when it was coupled with two and three flat plate collector respectively under winter condition (5-20/01/2016) in Ouargla (31.95°N, 5.4°E), south of Algeria.
