ADSORPTION HEAT PUMP SYSTEM AND COLD GENERATION METHOD

摘要

PROBLEM TO BE SOLVED: To reduce the regeneration temperature of a high-temperature-side adsorber in relation to an adsorption heat pump using a plurality of types of adsorbers.SOLUTION: A heat pump 12 comprises: an evaporator 14 evaporating an adsorbate; a first adsorber 20 adsorbing the adsorbate evaporated in the evaporator 14 and regenerated by receiving heat at a temperature equal to or higher than a first regeneration temperature; a second adsorber 22 adsorbing the adsorbate evaporated in the evaporator 14 and regenerated by receiving adsorption heat at a temperature equal to or higher than a second regeneration temperature lower than the first regeneration temperature from the first adsorber 20; a communication member 18 communicating the first adsorber 20 with the second adsorber 22 to allow migration of steam from the first adsorber 20 to the second adsorber 22 during regeneration of the first adsorber 20; and a condenser 24 condensing the steam desorbed from the second adsorber 22.
