Abstract

An air conditioning system for a building is provided that includes a heat sink, a heat source and a heat pump, the heat pump having a plurality of hollow elements especially comprising an adsorption agent. A heat-transporting fluid for heat exchange with the heat source and/or the heat sink can be distributed in a variable manner between a plurality of flow paths associated with the hollow elements, by means of a rotary valve, whereby the hollow elements are brought into thermal contact with the fluid at a variable temperature. Air in the building can be conditioned by means of the hollow elements by a temperature difference between the heat source and the heat sink. The heat pump is designed as a decentrally arranged structural unit spatially separated from at least either the heat source or heat sink.
