Abstract

A system and method for air-conditioning motor vehicles and, in particular, to an air-conditioning systems for motor vehicles having adsorption heat pumps. The apparatus includes a two adsorber chambers, each connected to a condenser and an evaporator via different connection elements; a vacuum shell for enclosing the adsorber chambers, the condenser, and the evaporator, wherein the vacuum shell is not self-supporting; and one or more adsorbers housed in the adsorber chambers, wherein the adsorbers are comprised of a carrier material coated by a sorbent. The method includes using an adsorption heat pump having one or more adsorber chambers, wherein adsorption and desorption are alternated between the adsorber chambers. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.
