An adsorption heat pump includes: an evaporator/condenser including a section that evaporates a first heat exchange-medium and pipe through which a second heat exchange-medium flows; first adsorption devices, each including an adsorption-section in which the first heat exchange-medium that has been evaporated reacts and retains the first heat exchange-medium, and pipe through which the second heat exchange-medium flows; and second adsorption device in which first heat exchange-medium that has been released from the first adsorption devices reacts and retains the first heat exchange-medium. The adsorption-section of the first adsorption device in a state reacting with the first heat exchange-medium is in communication with the evaporator/condenser section, and the adsorption-section of the first adsorption device is in a state having adsorbed the first heat exchange-medium is in communication with the second adsorption device adsorption-section, and the first adsorption device pipe is connected to the evaporator/condenser pipe in series, thereby generating cooling.
