ADSORPTION HEAT PUMP, VEHICULAR AIR CONDITIONER, DEHUMIDIFYING AIR CONDITIONER, AND METHOD FOR USING ADSORBING MATERIAL

PROBLEM TO BE SOLVED: To provide an adsorption heat pump capable of adsorbing and desorbing an adsorptive in a low relative steam pressure zone, a vehicular air conditioner, a humidifying air conditioner, and a method for using an adsorbing material. SOLUTION: The adsorption heat pump is equipped with adsorbing/desorbing parts 1, 2 including the adsorbing material for adsorbing and desorbing the adsorptive, an evaporating part 4 for evaporating the adsorptive connected to the adsorbing/desorbing parts 1, 2, and a condensing part 5 for condensing the adsorptive connected to the adsorbing/desorbing parts 1, 2. The adsorption heat pump is driven by a heat source of 100°C or lower. The adsorbing material is zeolite wherein (A) framework density is 10.0 T/1,000 3or higher and 16.0 T/1,000 3or lower, (B) a pore size is 3 or larger and 10 or smaller, and (C) differential adsorption heat is 40 kJ/mol or more and 65 kJ/mol or less. The zeolite contains aluminum and a phosphor in a skeletal structure and includes the low relative steam pressure zone wherein a change in a water adsorption amount when relative steam pressure is changed by 0.15 is 0.18 g/g or higher in a range of the relative steam pressure being 0.05 or more and 0.30 or more.
