Abstract

A sorption module may include a housing enclosing a working chamber including a sorption zone and a phase change zone arranged therein. The sorption module may also include a sorption structure, which may be arranged in the sorption zone and coupled in a heat-transmitting manner to a sorption path for guiding a sorption path medium, and a phase change structure, which may be arranged in the phase change zone and coupled in a heat-transmitting manner to a phase change path for guiding a phase change path medium. The sorption module may further include a control device configured to control a fluidic connection through which a working medium may be reversibly displaceable between the sorption zone and the phase change zone. The control device may include an actuator configured to control the fluidic connection depending on an adjustment of the actuator and an actuating drive configured to adjust the actuator.

4. The sorption module according to claim 1 , wherein:
the actuating drive is attached to an outside face of an outer wall of the housing; and
the actuator passes through a through-opening formed in the outer wall and cooperates with the fluidic connection in the working chamber.

5. The sorption module according to claim 4 , further comprising an elastic membrane connected to the actuator and the outer wall, the elastic membrane sealing the through-opening with respect to the working chamber.

6. The sorption module according to claim 1 , wherein:
