Description

[0001] Description

[0002] Air conditioning system

[0003] The invention relates to an air conditioning system, in particular for a track-guided vehicle, comprising at least one air conditioning unit and at least one measuring device associated with the air conditioning unit.

[0004] Furthermore, the invention relates to a track-guided vehicle for passenger transport, comprising at least one such air conditioning system or one further developed as described below.

[0005] Furthermore, the invention relates to a method for operating an air conditioning system, in particular for a track-guided vehicle, comprising at least one air conditioning unit and at least one measuring device assigned to the air conditioning unit.

[0006] Furthermore, the invention relates to a computer program product to be used in a computer of an air conditioning system for a rail-guided vehicle or in a computer of a rail-guided vehicle with such an air conditioning system.

[0007] Furthermore, the invention relates to a computer-readable recording medium on which a computer program product is recorded.

[0008] The invention further relates to a digital twin of such an air conditioning system or one further developed as described below, or of such an air conditioning system or one further developed as described below, or of such an air conditioning system or one further developed as described below, causes additional planning work for the maintenance workshops. In the event of a sudden failure of an air conditioning system, these workshops must reschedule the maintenance of other vehicles according to priority, provided spare parts are available. This results in unforeseen peaks in capacity at the workshops. Due to the low spare parts capacities of the maintenance workshops and the currently long delivery times for spare parts, vehicles can only be used to a limited extent or even not at all in regular operation.

[0009] Furthermore, the available energy in the vehicle is decreasing due to increasing consumption due to reduced performance of air conditioning units and air conditioning components.

[0010] Until now, the problem was usually solved by the air conditioning system software counting the frequency of errors occurring during operation when predefined operating pressures / temperatures in the refrigeration circuit are exceeded. If a predefined number of failed attempts is exceeded, an error message is generated, or the air conditioning unit or the air conditioning unit component is no longer enabled for operation (software-based blocking).

[0011] Based on this, the object of the invention is to provide an air conditioning system that enables damage to be detected.

[0012] This object is achieved by the air conditioning system of claim 1. Furthermore, the object is achieved by the track-guided vehicle of claim 11. Furthermore, the object is achieved by the method of claim 13, the computer program product of claim 24, the computer-readable recording medium of claim 25, and the digital twin of claim 26.

In this way, it is possible to detect when an electrical parameter has changed. This makes it possible to draw conclusions about the type of damage.

Likewise, training is possible, e.g., using AI. For this purpose, performance maps or similar data sets of the at least one air conditioning unit or the at least one air conditioning unit component can be used.

[0040] Preferably, the evaluation device is designed such that the data of the at least one electrical parameter are evaluated on the basis of the predefined value, the predefined set of values ​​and / or the predefined characteristic map of the parameter of the air conditioning unit and / or the air conditioning unit component.

[0043] In a further development of the air conditioning system, it can be provided that the evaluation device is designed to compare the at least one electrical parameter of the at least one measuring device of the at least one air conditioning device and / or of the at least one air conditioning device component with the sensor data of the at least one sensor of the at least one air conditioning device and / or of the at least one air conditioning device component.

[0045] It is possible that a feedback loop is formed between the at least one electrical parameter and the sensor data.

[0046] This makes it possible to check whether the sensor data and at least one electrical parameter are within a permissible value range relative to each other.

[0047] This allows conclusions to be drawn about the condition of the air conditioning system and it is possible that damage can be diagnosed for at least one air conditioning unit and / or at least one air conditioning unit component.

[0048] For example, if the electrical parameters are consistently high, but the sensor data are consistently within an inadmissible range, conclusions can be drawn about the condition of the air conditioning system.

[0059] By providing at least one second data interface, anomaly data can be transmitted remotely between the evaluation device and a land-based host computer. The land-based host computer is not part of the track-guided vehicle.

[0060] This makes it possible to collect data from multiple evaluation devices, multiple air conditioning systems, and / or multiple track-guided vehicles in a single land-based host computer. This makes it possible to document and compare data from different evaluation devices, different air conditioning systems, and / or different track-guided vehicles centrally in a single land-based host computer.

[0061] In the event of a premature defect or problem, the data at the time of the fault is collected, evaluated, and a workshop report is generated. This is then transmitted, for example, to the maintenance center.

This makes it possible to prevent overloading of the at least one air conditioning unit and / or the at least one air conditioning unit component. Furthermore, it is possible to adapt the load of the at least one air conditioning unit and / or the at least one air conditioning unit component to anomaly data and / or a resulting wear condition. This can save investment and operating costs.

[0065] Furthermore, the load management system can provide feedback on the current energy demand of the air conditioning system and / or the air conditioning unit and / or the air conditioning unit component, preferably in order to optimize the load management system.
