Abstract
In order to enable determining configuration information of an air conditioner, to enable displaying the cause of air conditioner problems during test operation and maintenance, and to enable easily verifying repair operations on a mobile terminal on the basis of the determination result, a display device displays configuration information, causes of problems, and repair operation procedures of the air conditioner, in which outdoor units having an outdoor heat exchanger and indoor units having an indoor heat exchanger are connected by coolant piping, and which circulates a coolant by means of a compressor. This display device is characterized by being provided with a control unit which determines the device configuration of the indoor units or the outdoor units of the air conditioner, a control unit which determines whether or not a problem has occurred, and a display unit which displays a repair operation procedure.
Description
technical field [0001] The invention relates to an air conditioner maintenance system and method thereof for trial operation and maintenance of the air conditioner. Background technique [0002] As background art in this technical field, there is Japanese Unexamined Patent Application Publication No. 2013-174384 (Patent Document 1). Patent Document 1 describes the problem that, when the indoor unit is installed at a position away from people in the air-conditioned space, the operating state displayed by the indoor unit may not be immediately confirmed. As a solution, it is described that "it is characterized by comprising: an indoor unit; a display unit installed on the indoor space side of the indoor unit; calculating display information of an (augmented reality) sign; and a driving unit that generates a drive control signal for displaying an AR sign corresponding to information on the air conditioner based on the display information calculated by the calculating unit, and...
