ADSORPTION HEAT PUMP AND USE OF ADSORBENT AS ADSORBENT FOR ADSORPTION HEAT PUMP

摘要

An adsorption heat pump using a heat source having a lower temperature and an adsorbent which has a large difference in water adsorption amount in adsorption/desorption and can be regenerated at a low temperature. An adsorption heat pump including an adsorbate, an adsorption/desorption part having an adsorbent for adsorbate adsorption/desorption, a vaporization part for adsorbate vaporization connected to the adsorption/desorption part, and a condensation part for adsorbate condensation connected to the adsorption/desorption part, wherein the adsorbent, when examined at 25° C., gives a water vapor adsorption isotherm which, in the relative vapor pressure range of from 0.05 to 0.30, has a relative vapor pressure region in which a change in relative vapor pressure of 0.15 results in a change in water adsorption amount of 0.18 g/g or larger.
