Experimental investigation of design parameters of solar glass desiccant box type system for water production from atmospheric air

Abstract

In this paper, experiments have been performed in order to determine the design parameters, i.e., air gap height, inclination angle, effective thickness of glass, and effective number of glazing for the water production from atmospheric air by using silica gel as solid desiccant material. Experiments have been performed in the Indian climatic condition at NIT Kurukshetra, India [29° 58′ (latitude) North and 76° 53′ (longitude) East]. A newly designed solar glass desiccant box type system, three in numbers, has been used. It is found that design parameters for the maximum production of water from the atmospheric air are air gap height as 0.22 m, inclination in angle as 30°, effective thickness of glass as 3 mm, and number of glazing as single.
