An empirical evaluation of an integrated inclined solar water desalination system with spray jets variation

Abstract

In this study, the productivity of an integrated inclined solar water desalination system with spray jets was empirically investigated. The effects of the feed water flow rate, solar radiation, ambient temperature, absorber plate temperature, cavity air temperature, glass cover temperature, variation in number of spray jets, and inlet and outlet temperature of the feed water on the daily production of the system were studied. The results show that the system productivity increases with two spray jets rather than with four and six jets tested on the system. The daily production also increases by cooling the system glazing and by solar radiation intensity. The inclusion of a wick (black cloth) on the absorber plate has a significant effect on the system production. The wick improved the daily production of the system by 23%. The daily production of the system with a wick on the absorber plate in the summer season is recorded as 6.41 kg/m(2) while the daily production with a bare plate absorber is recorded as 5.19 kg/m(2). The system (with wick) has a daily production of 3.327 kg/m(2) in the winter season. The experimental results in this study were compared with published data related to solar desalination units.
