Abstract

An adsorption refrigeration device includes a first chamber with an adsorber/desorber material and a second chamber with an evaporator/condenser device. The first and second chambers are in fluid connection via a pipeline. The fluid connection between the chambers is blocked in a first functional position and opened in a second functional position via a valve device that is arranged in the pipeline. The valve device has a valve element with a variable diameter. The valve element has two functional positions. In the first functional position, the valve element has a first diameter by which it fills an internal cross section of the pipeline with tight contact with an inner wall of the pipeline. In the second functional position, the valve element has a second diameter that is smaller than the first diameter such that a gap is opened between the inner wall of the pipeline and the valve element.

First claim

The invention claimed is:

1. An adsorption refrigeration device, comprising:
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 portion 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 portion of the pipeline and the valve element.

2. The adsorption refrigeration device as claimed in claim 1 , wherein:
the valve element has an elastic sleeve surrounding a working chamber,
the working chamber is sealed against the pipeline, the first chamber, and the second chamber,
the working chamber is actively connected to a control valve device so that (i) in the first function position, the working chamber is configured to be pressurized through the control valve device with a first pressure and (ii) in the second function position, the working chamber is configured to be pressurized through the control valve device with a second pressure, and
the first pressure is higher than the second pressure.

3. The adsorption refrigeration device as claimed in claim 2 , wherein in the first function position, the working chamber is vented via the control valve device to an environment of the adsorption refrigeration device.

4. The adsorption refrigeration device as claimed in claim 2 , wherein in the second function position, the working chamber is fluidically connected via the control valve device to a vacuum source.

5. The adsorption refrigeration device as claimed in claim 1 , wherein the inner wall portion against which the valve element lies tightly in the first function position is a constriction of an inner wall of the pipeline.

6. The adsorption refrigeration device as claimed in claim 1 , wherein the valve element is configured as one or more of a rubber gaiter and a bellows.

7. The adsorption refrigeration device as claimed in claim 1 , wherein:
the valve element has an elastic sleeve surrounding a working chamber; and
the elastic sleeve extends from the pipeline to a location outwardly of the pipeline.

8. The adsorption refrigeration device as claimed in claim 7 , wherein the elastic sleeve extends from the pipeline to a location outwardly of the at least one first chamber and the at least one second chamber.

9. The adsorption refrigeration device as claimed in claim 1 , wherein:
the pipeline includes a first portion with a first diameter, a second portion with a second diameter, and a third portion with a third diameter;
the second diameter is smaller than the first diameter and smaller than the third diameter;
the second portion is located between the first portion and the third portion;
the valve element has an elastic sleeve surrounding a working chamber; and
the elastic sleeve in the second function position extends at least from the first portion through the second portion to the third portion.

10. The adsorption refrigeration device as claimed in claim 9 , wherein:
the elastic sleeve extends from the pipeline to a location outwardly of the pipeline.

11. The adsorption refrigeration device as claimed in claim 10 , wherein the elastic sleeve extends through the at least one first chamber or the at least one second chamber to a location outside of the at least one first chamber and the at least one second chamber.

12. 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.

13. 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.
