We propose a new heat-and-mass transfer device that permits 
simultaneous heat and moisture regeneration in the ventilation system, 
provides anti-icing at the heat-exchanger outlet, and maintains comfortable 
humidity in a room. In this device, ahead of the heat-accumulating 
medium acting as a heat regenerator, a fine-grained adsorbent that 
controls the humidity of air flows is located. In the first part of 
the work, we have investigated the cyclic process of heat exchange 
(in the absence of adsorbent) and conducted its optimization for attaining 
maximum regeneration of heat. It has been shown that the regeneration 
efficiency can exceed 90%.
