Abstract

An air-conditioning system includes an air-conditioning apparatus including an outdoor unit and an indoor unit having a radiation temperature sensor that detects radiation temperature in a space to be air-conditioned, a controller that communicates with the indoor unit and acquires detection data from the radiation temperature sensor, and a terminal that communicates with the controller and acquires the detection data from the controller. The terminal detects a change in detection data and outputs the change.

First claim

1 . An air-conditioning system comprising:
an air-conditioning apparatus including an outdoor unit and an indoor unit having a radiation temperature sensor configured to detect radiation temperature in a space to be air-conditioned; a controller configured to communicate with the indoor unit and acquire detection data from the radiation temperature sensor; and a terminal configured to communicate with the controller and acquire the detection data from the controller, the terminal being configured to output information on whether a change of the detection data is larger than a preset threshold.

2 . The air-conditioning system of claim 1 ,
wherein the terminal is configured to transmit a test run instruction to cause the air-conditioning apparatus to perform a test run, and the controller is configured to transmit to the terminal, when receiving the test run instruction, the detection data acquired in advance from the indoor unit before the test run, and then cause the air-conditioning apparatus to perform the test run, acquire from the indoor unit, when the air-conditioning apparatus performs the test run, the detection data after the test run is performed, and transmit the detection data after the test run and acquired from the indoor unit to the terminal.

3 . The air-conditioning system of claim 2 ,
wherein the terminal is configured to detect a change between the detection data before the test run and the detection data after the test run is performed, and output the change.

4 . The air-conditioning system of claim 1 ,
wherein the indoor unit includes a test run switch for causing the air-conditioning apparatus to perform a test run, is configured to transmit, when the test run switch is turned on, the detection data acquired before the test run switch is turned on, to the controller, and transmit to the controller, after the test run is started, the detection data acquired after the test run is started.

5 . The air-conditioning system of claim 4 ,
wherein the terminal is configured to detect a change between the detection data acquired before the test run switch is turned on and the detection data acquired after the test run is started, and output the change.

6 . The air-conditioning system of claim 1 ,
wherein the terminal includes a display unit configured to display image data, and is configured to generate the image data representing distribution of the radiation temperature in the space to be air-conditioned according to the detection data acquired from the controller, and display the image data on the display unit.

7 . The air-conditioning system of claim 1 ,
wherein the controller is configured to periodically acquire the detection data from the indoor unit while the air-conditioning apparatus is performing the test run, and store the detection data.

8 . The air-conditioning system of claim 1 ,
wherein the controller is configured to store a plurality of pieces of the detection data, and transmit the stored detection data in response to a request from the terminal.

9 . The air-conditioning system of claim 1 ,
wherein the indoor unit and the controller are configured to communicate with each other by a first communication method, and the controller and the terminal are configured to communicate with each other by a second communication method different from the first communication method.

10 . The air-conditioning system of claim 1 ,
wherein the indoor unit and the controller are connected to each other via a dedicated line for communication, and the controller and the terminal are configured to communicate with each other by short-range wireless communication.

11 . The air-conditioning system of claim 1 ,
wherein the controller is a remote controller configured to control an operation of the indoor unit, and the terminal is a portable terminal.
