IMPROVING THERMAL PERFORMANCE OF A DOUBLE-SLOP SOLAR STILL UNDER HOT, HUMID AND DUSTY CLIMATIC CONDITIONS

Thermal Performance of a Double-pass Solar Air Heater

This study analyzes the thermal performance of solar thermal energy using double-pass absorber plate in Sanandaj, Iran. To this end, a mathematical model was encoded according to the energy and exergy balance equations and solved by MATLAB software. Given the environmental conditions and radiation intensity of a winter day in Sanandaj, the effects of external parameters such as radiation intens...

Optimization of the PCM-integrated solar domestic hot water system under different thermal stratification conditions

Many researchers have investigated how to increase the overall efficiency of solar-driven thermal systems. Several key parameters, such as collector efficiency and storage tank characteristics, may impose some constraints on the annual solar fraction (ASF) of such systems. In this paper, the behaviour of integrating the phase change material (PCM) in SDHW systems is modelled and optimized n...

Experimental Analysis of a Vertical, Double-Effect Diffusion Solar Still

Experimental study of the thermal performances of a composite roof including a reflective insulation material under tropical humid climatic conditions

This paper deals with the evaluation of the outdoor performances of a composite roof, composed of a corrugated iron rooftop, a radiant barrier and a ceiling made of wood, each component being separated by an air space. This assembly is mounted on a small-scale test cell, named Isotest, designed and set up for research purposes. Isotest is installed on an experimental platform, dedicated to the ...
