In Fig. 9, for the case of the bottom flow, it can be seen that when the air inlet velocity is maintained at 1 m/s, the maximum temperature of the air outlet is 45 °C at an ambient temperature of 34 °C which is 11 °C above the ambient temperature.
He would use maximum air, less water.
They had already been put into a storeroom which had no air outlet.
Fig. 9 Comparison of air outlet temperature for top and bottom flow over the day.
The air outlet is aligned differently in position to the four rooms.
Hence, a balance has to be maintained between collector efficiency and air outlet temperatures.
The generated pure water is exhausted with the residual air and a small fraction of formation heat through the "air outlet" pipe.
If the air velocity is increased in order to improve the efficiency, the air outlet temperature from the collector would decrease.
(3) Gradually, the heated moist air goes up and leaves the drying chamber through the air outlet at the high end of the dryer.
