4.2 The active solar distillation system with external condenser and enhanced water recovery

To simulate the performance of the active distillation system, the computer program is first input with the measured weather parameters of the site and the measured values of the air entering the still's relative humidity and temperature. The results of the simulation program include still water temperature, glass temperature, basin temperature, air leaving the still temperature and relative humidity, air leaving the condenser temperature, and air leaving heat recovery's temperature and relative humidity, as well as the distillate production from the glass and from the condenser. Figure 6 shows the measured and predicted temperatures and relative humidity of the air leaving the still, while Figure 7 shows those of the air leaving the preheater. Figure 8 shows the air leaving the still calculated and measured moisture content, and Figure 9 shows the basin water calculated and measured temperatures. Figures 10 and 11 correspondingly show the calculated and measured distillate yields from the glass and the condenser.
