An adsorption thermal storage apparatus formed of an evacuated vessel comprising therein a refrigerant, and an adsorbent heating or cooling section and a refrigerant condensing or evaporating section located in communication with each other, the former section including an adsorbent and finned heat transfer tubes, the latter section including heat transfer tubes placed in dishes. An adsorption thermal storage system comprising the aforesaid apparatus; a heat source (e.g. a condenser of a compression refrigerator) for adsorbent heating; a cold source (e.g. an evaporator) for refrigerant condensation; an exothermic heat source (e.g. cooling tower); an endothermic heat source (e.g. air cooling coil); and a utilization equipment (e.g. air conditioner), the foregoing elements being connected so that during thermal storage period, the adsorbent heating or cooling section and the refrigerant condensing or evaporating section communicate with the heat source and the cold source, respectively, whereas during utilization period, the adsorbent section communicates with the exothermic heat source or heat utilization equipment and the refrigerant section communicates with cold utilization equipment or the endothermic heat source. By the desorption, the refrigerant is condensed and thermal energy is stored whereas cold is generated by latent heat of evaporation of the refrigerant liquid and heat, by adsorption heat of the refrigerant vapor, whereby heat and cold may be utilized singly or simultaneously.
