A new system controls in temperature and humidity. This system consist of two subsystems the first for occupied zoon return air circulation. The second one is for condenser circulation. The whole system consists of heat exchanger and contain two subsystems. The first is for occupied zoon circulating air and the second is for condenser air circulation. For the occupied zoon ...

The aim of the study is to enhance the productivity of solar stills using an unsaturated porous medium (sand) initially saturated by salty water and using concentrating reflector. This paper concentrates on the mathematical model for the porous medium and its solution using a finite volume approach. Previous studies for solar still, using porous medium have been mainly concerned with ... Read more

This current work studies the effects of initially saturated porous medium and humid air region on the water vapor condensation. The experiments of the present study were conducted on a double slope solar still (DSSS). The DSSS liner dimension is 1.9 m by 0.86 m by (0.02 m, 0.03 m and 0.04 m). The effect of porous medium thickness on ... Read more

The goal of the study is to enhance the productivity of solar stills using an unsaturated porous medium initially saturated by salty water and using concentrating reflector. This paper concentrates only on the mathematical model for the porous medium and its solution using a finite-volume approach. The previous studies dealt with wick medium with high water content and liquid saturation ... Read more

The experimental work was carried on two different types of air outlets under the same operating conditions to determine thermal characteristics, and fluid dynamic. The first was sidewall grille while the other was ceiling grille. Experimental data were recorded for cooling case at different volumetric flow rates 135, 180, and 225 m3 /hr, and four different distributed loads 40, 60, ... Read more
