Abstract:
A heat storage system for a vehicle, comprising:an adsorbent for adsorbing and desorbing medium, the adsorbent having a medium-adsorbing capacity that is reduced in accordance with a temperature increase of the adsorbent, and generating heat when adsorbing gas medium; an adsorption chamber for containing the adsorbent therein; a waste heat supplier for supplying waste heat generated in the vehicle to the adsorbent; an adsorption heat supplier for supplying the heat generated by the adsorbent to an apparatus requiring warm-up operation, the apparatus being mounted in the vehicle; a refrigerator for cooling air to be blown into a passenger compartment of the vehicle, the refrigerator including a refrigerant-medium heat exchanger for performing heat-exchange between the medium and refrigerant circulated in the refrigerator; a first valve for opening and closing a first passage through the gas medium desorbed from the adsorbent is introduced from the adsorption chamber to the refrigerant-medium heat exchanger; a liquid-medium storage chamber for storing liquid medium cooled and condensed in the refrigerant-medium heat exchanger, the liquid medium being heated and vaporized to be gas medium in the refrigerant-medium heat exchanger by absorbing heat; a second valve for opening and closing a second passage through which the liquid-medium storage chamber and the adsorption chamber communicate with each other, wherein: the first valve opens the first passage for a predetermined time when a temperature of the apparatus is equal to or higher than a predetermined temperature, and closes the first passage after the predetermined time passes; and the second valve opens the second passage at least when the temperature of the apparatus is lower than the predetermined temperature.
