Adsorption refrigeration device, arrangement and motor vehicle

An arrangement, comprising:

• a motor;
• and
• an adsorption refrigeration device including:
• at least one first chamber with an adsorber/desorber material, and
• at least one second chamber with an evaporator/condenser device, the first chamber and the second chamber fluidically connected together via a pipeline,
• wherein the fluidic connection between the first chamber and the second chamber is configured to be blocked in a first function position and opened in a second function position via a valve device arranged in the pipeline, and
• wherein the valve device has a valve element with a variable diameter, the valve element configured such that (i) in the first function position, the valve element has a first diameter with which the valve element fills an inner cross section of the pipeline and lies tightly against an inner wall of the pipeline and (ii) in the second function position, the valve element has a second diameter that is smaller than the first diameter so that a gap is opened between the inner wall of the pipeline and the valve element,
• wherein the motor and the adsorption refrigeration device are fluidically connected to each other such that the adsorption refrigeration device is configured to be supplied with waste heat from the motor.

A motor vehicle, comprising:

• an arrangement with a motor and an adsorption refrigeration device, the adsorption refrigeration device including:
• at least one first chamber with an adsorber/desorber material, and
• at least one second chamber with an evaporator/condenser device, the first chamber and the second chamber fluidically connected together via a pipeline,
• wherein the fluidic connection between the first chamber and the second chamber is configured to be blocked in a first function position and opened in a second function position via a valve device arranged in the pipeline, and
• wherein the valve device has a valve element with a variable diameter, the valve element configured such that (i) in the first function position, the valve element has a first diameter with which the valve element fills an inner cross section of the pipeline and lies tightly against an inner wall of the pipeline and (ii) in the second function position, the valve element has a second diameter that is smaller than the first diameter so that a gap is opened between the inner wall of the pipeline and the valve element,
• wherein the motor and the adsorption refrigeration device are fluidically connected to each other such that the adsorption refrigeration device is configured to be supplied with waste heat from the motor.
