Abstract
For the purpose of effective regeneration of an adsorbent applied for a desiccant air conditioning, microwave irradiation to the adsorbent has been proposed. To investigate the effects of microwave irradiation on the rate of water desorption from zeolite and silica gel, the experiment was conducted in a N_2 flow type adsorption column equipped with a microwave irradiator. The desorption amount of water from zeolite with microwave irradiation for 15 minutes was about 1.6 times larger than that with hot air heating. The water desorption from silica gel also indicated similar tendency to that from zeolite. The acceleration of desorption of adsorbed water from adsorbents was achieved by using microwave irradiation. However, change in desorption rate for zeolite was different from that for silica gel in an initial period of desorption.
