Abstract

A system for cooling and/or heating aircraft devices to be cooled and/or heated includes a first individual cooling and/or heating system associated with a first aircraft device to be cooled and/or heated, a second individual cooling and/or heating system associated with a second aircraft device to be cooled and/or heated, a cooling and/or heating energy supply apparatus adapted to supply cooling and/or heating energy generated by the first and/or the second individual cooling and/or heating system to the first and/or the second aircraft device to be cooled and/or heated, a control device adapted to receive and process signals characteristic of the cooling and/or heating requirements of the first and/or the second aircraft device to be cooled and/or heated and of the load condition of the first and/or the second individual cooling and/or heating system.

First claim

The invention claimed is:

1. A system for cooling and/or heating aircraft devices to be cooled and/or heated, comprising:
a first individual cooling and/or heating system associated with a first aircraft device to be cooled and/or heated;
a second individual cooling and/or heating system associated with a second aircraft device to be cooled and/or heated;
a cooling and/or heating energy supply apparatus which is adapted to supply cooling and/or heating energy generated by the first and/or the second individual cooling and/or heating system to the first and/or the second aircraft device to be cooled and/or heated; and
a control device which is adapted to receive and process signals characteristic of cooling and/or heating requirements of the first and/or the second aircraft device to be cooled and/or heated and of a load condition of the first and/or the second individual cooling and/or heating system, and which is further adapted to control, on the basis of said signals, an operation of the first and/or the second individual cooling and/or heating system and/or the supply of cooling and/or heating energy generated by the first and/or the second individual cooling and/or heating system to the first and/or the second aircraft device to be cooled and/or heated.

2. The system according to claim 1 , wherein the control device is adapted to control the operation of the first and/or the second individual cooling and/or heating system and/or the supply of cooling and/or heating energy generated by the first and/or the second individual cooling and/or heating system to the first and/or the second aircraft device to be cooled and/or heated in such a way that the overall energy requirements of the first and the second individual cooling and/or heating system which are required by the first and/or the second individual cooling and/or heating system to generate the cooling and/or heating energy are minimized.

3. The system according to claim 1 , wherein the control device is adapted to control the operation of the first and/or the second individual cooling and/or heating system and/or the supply of cooling and/or heating energy generated by the first and/or the second individual cooling and/or heating system to the first and/or the second aircraft device to be cooled and/or heated while taking account of load-dependent energy requirement data of the first and the second individual cooling and/or heating system.

4. The system according to claim 3 , wherein the control device is adapted to access the load-dependent energy requirement data of the first and the second individual cooling and/or heating system stored in a data base and/or to calculate the load-dependent energy requirement data of the first and the second individual cooling and/or heating system using appropriate equations.

5. The system according to claim 1 , wherein the control device is adapted, when controlling the operation of the first and/or the second individual cooling and/or heating system and/or the supply of cooling and/or heating energy generated by the first and/or the second individual cooling and/or heating system to the first and/or the second aircraft device to be cooled and/or heated, to give a higher priority to the supply of cooling and/or heating energy to the first or the second aircraft device to be cooled and/or heated over the supply of cooling and/or heating energy to the second or the first aircraft device to be cooled and/or heated if the overall cooling and/or heating requirements of the first and/or the second aircraft device to be cooled and/or heated exceed the maximum overall cooling and/or heating energy generating capacity of the first and the second individual cooling and/or heating system.

6. The system according to claim 5 , wherein the control device is adapted, when prioritizing the first or the second aircraft device to be cooled and/or heated over the second or the first aircraft device to be cooled and/or heated with regard to the supply of cooling and/or heating energy, to take account of data characteristic of the relevance of the first and/or the second aircraft device to be cooled and/or heated to the operation of the aircraft.

7. The system according to claim 6 , wherein the data characteristic of the relevance of the first and/or the second aircraft device to be cooled and/or heated to the operation of the aircraft are data dependent on the operating state of the aircraft and in that the control device is adapted to receive and process signals characteristic of the operating state of the aircraft, and to carry out the prioritizing of the first or the second aircraft device to be cooled and/or heated over the second or the first aircraft device to be cooled and/or heated with regard to the supply of cooling and/or heating energy in dependence on the signals characteristic of the operating state of the aircraft.

8. A method for cooling and/or heating aircraft devices to be cooled and/or heated, comprising:
