Abstract

A cooling medium compressor arrangement is comprised of a compressor, a control mechanism electrically connected with the compressor, and a gas sensor, and the safety of the arrangement is improved by arranging the control mechanism and the gas sensor in a common housing.

Claims

1. A cooling medium compressor arrangement comprising:

a compressor;

a gas sensor; and

a control mechanism electrically connected with the compressor and the gas sensor;

wherein the control mechanism and the gas sensor are arranged in a common housing.

2. The arrangement of claim 1, wherein the housing at least in part is gas permeable.

3. The arrangement of claim 2, wherein the housing has a gas permeable region in which the gas sensor is arranged, and a gas tight region in which the control mechanism is arranged.

4. The arrangement of claim 1, wherein the gas sensor is integrated into an electronic circuit of the control mechanism.

5. The arrangement of claim 4, wherein the gas sensor is a component of a voltage dividing arrangement.

6. The arrangement of claim 1, wherein the gas sensor is connected with a microcontroller or an ASIC.

7. The arrangement of claim 6, wherein the microcontroller forms an evaluation and memory apparatus by means of which a timewise course of a cooling medium loss is documentable.

8. The arrangement of claim 1, wherein along with the gas sensor at least one further gas sensor is provided.

9. The arrangement of claim 8, wherein a selecting mechanism is provided which brings an as yet non-used gas sensor into use following at least one of the following criteria:

a) a predetermined operating time of a used gas sensor has elapsed, or

b) a used gas sensor is functionally impaired.

10. The arrangement of claim 8, wherein a number of gas sensors operate simultaneously.
