Abstract

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%.
