Performance improvement of a solar assisted desiccant air conditioning coupled with condenser for water production

Abstract

In the present paper, the performances of a solar desiccant air conditioning system coupled with the condenser for distillate water production are numerically investigated. The aim of the present study condensed the water vapor from the regeneration air out from a solar desiccant air conditioning by feeding it to the condenser to production the distillate water. Production the distillate water, air conditioning, and energy saving represent the objective of this study. The results show that (i) as process air discharge increases from 150–450 m3/h, supply air temperature increases from 18.5–21.6 °C, distillate production decreases from 1.635–0.105 l/h, cooling COP increases from 0.406–0.724, and overall COP decreases from 0.918–0.873 (ii) as the regeneration air discharge increases from 75–225 m3/h, supply air temperature decreases from 21.8–18.4 °C, distillate production increases from 0.009–3.024 l/h, cooling COP decreases from 0.714–0.431, and overall COP increases from 0.718–1.029 (iii) as the regeneration temperature increases from 75–100 °C, supply air temperature decreases from 21.2–18.9 °C, distillate production increases from 0.285–1.41 l/h, cooling COP decreases from 0.704–0.555, and overall COP increases from 0.815–0.926.
