Problems solved by technology

Therefore, it is difficult to determine the fault factor by only performing threshold judgment on a single component
In addition, the fault factor is affected by the difference caused by the installation conditions and the difference caused by the model, so the display of the fixed fault code cannot estimate the fault factor with high accuracy.
[0009] In addition, in the invention described in Patent Document 2, the operator identifies the fault location based on the information displayed on the display unit, so whether the fault location can be correctly identified depends on the skill and experience of the operator.
That is, in the invention described in Patent Document 2, it is difficult to estimate the fault location with high accuracy.

Embodiment approach 1

[0019] The air conditioner according to Embodiment 1 will be described below.

[0020] [Structure of air conditioner]

[0021] figure 1 It is a block diagram showing an example of the configuration of the air conditioner 1 according to the first embodiment.

[0022] like figure 1 As shown, the air conditioner 1 is configured to include an outdoor unit 10 , an indoor unit 20 , and a remote controller (hereinafter appropriately referred to as “remote controller”) 30 . The outdoor unit 10 and the indoor unit 20 are connected using a wired or wireless first connection line 2 and using a first communication method. The indoor unit 20 and the remote controller 30 are connected by a wired or wireless second connection line 3 and a second communication method.

[0023] In addition, the remote controller 30 is connected to the information terminal 40 using the third wireless connection line 4 and the third communication method. As the third communication method, for example, short...

Embodiment approach 2

[0072] Next, an air conditioner according to Embodiment 2 will be described. The air conditioner according to the second embodiment differs from the first embodiment described above in that the information terminal 40 includes a neural network computing unit.

[0073] Figure 4 It is a block diagram showing an example of the configuration of the air conditioner 1 according to the second embodiment. like Figure 4 As shown, in the air conditioner 1 according to the second embodiment, the information terminal 40 is provided with a neural network computing unit 49 . In addition, in the following description, the same reference numerals are assigned to the same parts as those of the first embodiment described above, and description thereof will be omitted.

[0074] Microcomputer 32 in remote controller 30 receives sensor information and control information transmitted from outdoor unit 10 via fourth communication unit 31 and supplies them to fifth communication unit 34 . The f...

Embodiment approach 3

[0081] Next, an air conditioner according to Embodiment 3 will be described. The air conditioner according to Embodiment 3 differs from Embodiments 1 and 2 above in that a neural network computing unit is provided on the cloud 50 .

[0082] Figure 5 It is a block diagram showing an example of the configuration of the air conditioner 1 according to the third embodiment. like Figure 5 As shown, in the air conditioner 1 according to Embodiment 3, the neural network computing unit 59 is installed on the cloud 50 . In addition, in the following description, the same code|symbol is attached|subjected to the part common to Embodiment 1 and 2 mentioned above, and description is abbreviate|omitted.

[0083] Microcomputer 32 in remote controller 30 receives sensor information and control information transmitted from outdoor unit 10 via fourth communication unit 31 and supplies them to fifth communication unit 34 . The fifth communication unit 34 performs the communication processi...

Abstract

The present invention relates to an air conditioner and an air conditioning system. The air conditioner includes: an outdoor unit and an indoor unit provided with various equipment and piping forming a refrigerant circuit, and a remote controller connected to the indoor unit; For sensors of the temperature state of equipment and piping, the outdoor unit or indoor unit is provided with a memory for storing sensor information indicating the detection result of the sensor and control information indicating the control state of the equipment. The remote controller has: a neural network computing unit, which information indicating the state of each part based on the sensor information and control information acquired from the memory at the same time as an input value, and the estimated failure factor as an output value, using a neural network to calculate the possibility of the failure factor; and displaying unit, which displays the operation result of the neural network operation unit.

Description

technical field [0001] The present invention relates to an air conditioner and an air conditioning system that estimate a failure factor. Background technique [0002] A remote controller included in a conventional air conditioner management system is connected to the indoor unit via a transmission line, and holds data such as operation history and fault codes received from the indoor unit. In addition, the remote controller can transmit the held data to a portable terminal such as a user's mobile phone. [0003] In addition, the remote control holds operating information such as the set temperature of the air conditioner, information indicating the type of the air conditioner, the operating time of the air conditioner, the current consumption and rotation speed of the compressor in the outdoor unit, a code indicating the cause of the failure, and the outside air temperature. and other data. Such various information can be transmitted from the mobile terminal to a service ...
