Outline of Final Research Achievements |
To develop a new adsorbent-filled heat exchanger for an adsorption heat pump (AHP), an adsorbent of Wakkanai siliceous shale, which is a natural mesoporous material, impregnated with 20wt% lithium chloride, was prepared. In addition, for the enhancement of heat conductivity, the mixture of aluminum fibers also conducted. From the results of cooling ability evaluation, at the cycle time of 4 min regeneration, 1 min precooling and 7 min adsorption, the COP and SCP showed 0.44 and 433 W/kg, respectively. A 3 dimension model about the heat and mass transfer in the heat exchanger with adsorbent was constructed, and the computer program for numerical analysis was created. For the making of 10kW AHP, element design was carried out.
