Adsorption-type heat storage system

Provided inside a zeolite adsorber is a heat exchanger which is a component of a heating circuit which inter alia also leads via a useful heat exchanger in which the useful heat can be employed, for example, to heat a vehicle interior. The heating circuit has a bypass which circumvents the adsorber and in which a timing valve is provided. By means of the timing operation of this timing valve, a recirculating pump can start up the heating circuit even through the adsorber, although in the preceding desorption process the heating medium has changed its phase state in the adsorber heat exchanger, with the result that a steam bubble was produced there. The heating medium can be fed to the useful heat exchanger by mixing superheated steam from the adsorber and liquid via the bypass immediately downstream of the adsorber with the aid of conventional hot water hoses. Also specified are advantageous design details of an adsorber/evaporation chamber unit.
