Air-conditioning system

1. An air-conditioning system, comprising:

an air-conditioning apparatus including an outdoor unit, an indoor unit, and a remote controller connected to the indoor unit, the outdoor unit and the indoor unit including devices and pipes included in a refrigerant circuit;

an information terminal configured to connect to the remote controller and to communicate with the remote controller; and

a server connected to the information terminal via a network and configured to communicate with the information terminal,

a first memory contained within the outdoor unit and storing outdoor-unit identification information including a product model name and a serial number of the outdoor unit which was written in the first memory prior to operation of the air-conditioning system,

a second memory contained within the indoor unit and storing indoor-unit identification information including a product model name and a serial number of the indoor unit which was written in the second memory prior to operation of the air-conditioning system, and

a third memory contained within the remote controller and configured to store the outdoor-unit identification information and the indoor-unit identification information, wherein the remote controller includes a display unit configured to display error information representing details of an abnormal condition when the abnormal condition occurs in the air-conditioning apparatus and a microcomputer, and during operation of the air-conditioning system, the microcomputer of the remote controller is configured:

to obtain the outdoor-unit identification information from the outdoor unit and to obtain the indoor-unit identification information from the indoor unit,

to store the obtained outdoor-unit identification information and indoor-unit identification information into the third memory, and

to display on the display unit the stored outdoor-unit identification information and indoor-unit identification information together with the error information when an abnormal condition occurs in the air-conditioning apparatus, and

wherein the information terminal is configured:

to obtain the outdoor-unit identification information and the indoor-unit identification information from the remote controller when the information terminal is connected to the remote controller, and

to transmit the obtained outdoor-unit identification information and indoor-unit identification information to the server.

2. The air-conditioning system of claim 1 ,

wherein the information terminal has contact information previously set and representing a maintenance-operator's contact and is configured to transmit the contact information to the remote controller when the information terminal is connected to the remote controller, and

wherein the remote controller is configured to store the contact information obtained from the information terminal into the third memory.

3. The air-conditioning system of claim 2 , wherein when an the abnormal condition occurs in the air-conditioning apparatus, the remote controller is configured to cause the display unit to display the contact information together with the error information.

4. The air-conditioning system of claim 1 ,

wherein the information terminal has installation location information previously set about an installation location including a position of the air-conditioning apparatus,

wherein when the information terminal receives the outdoor-unit identification information and the indoor-unit identification information, the information terminal is configured to associate the outdoor-unit identification information and the indoor-unit identification information with the installation location information, and

wherein the information terminal is configured to transmit the outdoor-unit identification information, the indoor-unit identification information, and the installation location information associated with each other to the server.

5. The air-conditioning system of claim 4 , wherein the information terminal is

configured to be operated to set the installation location information.

6. The air-conditioning system of claim 4 ,

wherein the information terminal includes a position information obtaining unit which obtains position information representing a current position, and

wherein the information terminal is configured to set the position information obtained by the position information obtaining unit of the information terminal as the installation location information.
