Maximal values of efficiency coefficient (about of 53 – 57 %) correspond with the
relative humidities of 40 – 60 % at the vapor-air-flow rates of 0.2 – 0.6 m/s at heights
of adsorbent layer 0.25 – 0.5 m. The value η is observed to be negligibly changed as
vapor-air-flow temperature increased (Fig. 4).

Then, to develop methods of increasing of the efficiency coefficient structure of
heat input was analysed. According to Fig. 5, the most significant input items are heat
of evaporation and heat of desorption.
