The results of experimental testing at varying supply inlet temperature and inlet relative humidity for different regeneration temperatures at constant regeneration humidity are shown in the following graphs.

Figure 4 shows the moisture removal from the supply air stream at varying relative humidity and temperature for a regeneration temperature of 50 °С. It is obvious that the moisture removal increases with both increasing relative humidity and temperature of the supply air. The maximum moisture removal for supply inlet conditions of 40°C/95% RH was measured at 17 g/kg d. a.. In this point the driving temperature difference is only 10K between supply and regeneration air, however the difference in absolute humidity between supply and regeneration air is 40 g/kg d. a..

The same parameters as in Figure 4 are shown in Figure 5 for a regeneration temperature of 80°C. It can be observed that the moisture removal at 80°C regeneration temperature is generally greater than at 50°C regeneration temperature. A larger moisture removal capacity is clearly noticeable in Figure 5 at high supply inlet humidity and supply inlet temperatures of 30 and 40°C. However, at supply inlet temperatures of 10 and 20°C the difference in moisture removal between 50 and 80°C regeneration temperature is relatively small. In fact, the difference in moisture removal between 50 and 80°C regeneration temperature for supply inlet temperatures between 10 and 30°C and supply inlet relative humidity between 20 and 50% is smaller than 1 g/kg d. a. This shows that a regeneration temperature of 50 °C can almost achieve the same moisture removal at lower inlet humidity supply air.
