- the normal operating state database 38 and an error operating state of the aircraft cooling system 100 include data indicating the subordinate priority (priority 3) of the cooling energy consumers 20a-d in the cooling energy supply.
- the cooling energy consumers 20a-d of the third group are prioritized over the cooling energy consumers 18a-d of the second group in the supply of cooling energy (priority 2).
- the database 38 includes data to be cleared for the cooling power consumers 16a-d, 18a-d, 20a-d in a normal operating condition, and in a critical operating condition of the cooling power consumers 16a-d, 18a-d, 20a-d in the cooling power supply Priority are characteristic.
- the operating state dependent priority data stored in the database 38 in addition to the operating state of the refrigeration system 100, takes into account the operating state of the cooling energy consumers 16a-d, 18a-d, 20a-d.
- this target temperature is 20 ° C
- the target temperatures stored in the database 38 for the three groups of cooling energy consumers 16a-d, 18a-d, 20a-d respectively represent the temperature which circulates the refrigerant medium circulating in the refrigerant medium circuit 14 for cooling the individual groups of cooling energy consumers 16a-d, 18a Ideally, if only one group of cooling energy consumers 16a-d, 18a-d would have d, 20a-d would have to be supplied with cooling energy. That is, if only the first group of cooling energy consumers 16a-d would have to be supplied with cooling energy, the coolant medium would ideally have a temperature of 20 ° C.
- control system 10 comprises a control signal generation unit 40.
- the control signal generation unit 40 generates control signals which control the supply of cooling energy to the various groups of cooling energy consumers 16a-d, 18a-d, 20a-d in dependence on the operating status signals generated by the operating state detection unit 30.
- the operating state-dependent priority data stored in the database 38 are also taken into account.
- the signal generation unit 40 can, if desired or necessary, take into account the operating state of the individual cooling energy consumers 16a-d, 18a-d, 20a-d and / or signals characteristic of the ambient conditions.
- a cooling energy consumer 16a-d, 18a-d, 20a-d which in one particular operating state of the aircraft cooling system 100 has only a subordinate priority in the supply of cooling energy, can nevertheless be supplied cooling energy if a predetermined maximum temperature of the cooling energy consumer 16a-d , 18a-d, 20a-d and damage to the cooling energy consumer 16a-d, 18a-d, 20a-d is imminent, a reduction in the power of the cooling energy consumer 16a-d, 18a-d, 20a-d or a shutdown of Cooling energy consumer 16a-d, 18a-d, 20a-d but is not possible without jeopardizing the operational safety of the aircraft.
- control signals generated by the control signal generating unit 40 are passed via a data bus 42 to the refrigeration device 12 of the aircraft cooling system 100. Via a data bus 46, the individual groups of cooling energy consumers 16a-d, 18a-d, 20a-d control signals generated by the control signal generating unit 40 can be supplied.
- the control signals generated by the control signal generating unit 40 are used to control the cooling energy consumption of the cooling energy consumers 16a-d, 18a-d, 20a-d as desired.
- the maximum temperature of the refrigerant medium after the delivery of its cooling energy to the cooling energy consumers 16a-d, 18a-d, 20a-d be limited.
- the control signals generated by the control signal generating unit 40 may be directly supplied to the cooling power consumers 16a-d, 18a-d, 20a-d. Alternatively, however, it is also conceivable to supply the control signals generated by the control signal generating unit 40 to the individual cooling energy consumers 16a-d, 18a-d, 20a-d or to the individual groups of cooling energy consumers 16a-d, 18a-d, 20a-d associated with local controls , Furthermore, under the control of the control system 10, only the operation of the refrigeration device 12 and the distribution of the cooling energy generated by the refrigeration device 12 to the cooling energy consumers 16a-d, 18a-d, 20a-d can be controlled.
- cooling energy consumers 16a-d, 18a-d, 20a-d it is also conceivable to influence the operation of the cooling energy consumers 16a-d, 18a-d, 20a-d, i. For example, to reduce the power of a cooling energy consumer 16a-d, 18a-d, 20a-d, when this cooling energy consumer 16a-d, 18a-d, 20a-d is supplied with little cooling energy.
- control system 10 controls the operation of the refrigeration device 12 such that the refrigeration device 12 cools the refrigerant to be supplied to the refrigeration consumers 16a-d, 18a-d, 20a-d to a temperature corresponding to the lowest setpoint temperature of a group of stored in the database 38 Cooling energy consumers 16a-d, 18a-d, 20a-d adapted, taking into account the operating state-dependent priority data stored in the database 38 in a specific operating state of the aircraft cooling system 100 and / or the cooling energy consumers 16a-d, 18a-d, 20a-d with Cooling energy is supplied.
- the refrigeration device 12 is controlled by the control system 10 such that the refrigerant medium temperature corresponds to the lowest refrigerant medium temperature target temperature of the groups of cooling energy consumers 16a-d, 18a-d, 20a-d currently supplied with cooling energy.
