Display device, method, and program

A display method which is performed in an information terminal including an input device, a display device, a processing device, and a storage device, and which displays operation information of an air conditioner in which an outdoor machine including an outdoor heat exchanger and an indoor machine including an indoor heat exchanger are connected to each other by a refrigerant pipe, and a refrigerant is circulated by a compressor, the method being implemented with memory-stored executable instructions coupled to a processor of the information terminal, where the executable instructions when executed by the processor, cause the processor to perform the method, comprising:

• an acquisition step for causing the input device to acquire the operation information of the air conditioner;
• a storing step for causing the storage device to store the acquired operation information;
• an abnormality determination step for causing the processing device to determine whether or not abnormality has occurred in the outdoor machine or the indoor machine when the air conditioner operates;
• and
• a display step for causing the display device to display at least a first operation information display region and a second operation information display region for displaying time information and displaying operation information corresponding to the time information in respective time-series graphs,
• wherein in a case where, in the abnormality determination step, it is determined that the abnormality has occurred in the outdoor machine or the indoor machine, operation information of the outdoor machine or the indoor machine in which the abnormality has occurred, is displayed in the first or second operation information display region in the display step,
• the method further comprising:
• displaying a first operation information display region and a second operation information in the display region in line in a vertical direction or a transverse direction,
• upon determining that the abnormality has occurred in the outdoor machine or the indoor machine, displaying operation information of the outdoor machine in the first operation information display region in a time-series graph, and displaying operation information of the indoor machine, which is connected to the displayed outdoor machine by the refrigerant pipe, in the second operation information display region in a respective time-series graph, and
• displaying the operation information of the outdoor machine or the indoor machine in which the abnormality has occurred.

A display program which is operated in an information terminal including an input device, a display device, a processing device, and a storage device, and is executed in the processing device in order to cause the display device to display operation information of an air conditioner in which an outdoor machine including an outdoor heat exchanger and an indoor machine including an indoor heat exchanger are connected to each other by a refrigerant pipe, and a refrigerant is circulated by a compressor, the program causing the processing device to execute:

• a determination function of determining whether or not abnormality has occurred in the outdoor machine or the indoor machine when the air conditioner operates, based on information input from the input device;
• a display function of displaying the operation information to be input from the input device, controls the display unit to display a plurality of operation information display regions in a vertical direction or the transverse direction, and the operation information display region displays time information in a transverse direction and displays the operation information corresponding to the time information in a vertical direction in respective time-series graphs;
• and
• an abnormality display function of controlling the display unit to display operation information of the outdoor machine or the indoor machine in which the abnormality has occurred, in a time-series graph in one of the operation information display regions, and to display operation information of an indoor machine or an outdoor machine which is connected to the outdoor machine or the indoor machine in which the abnormality has occurred, by the refrigerant pipe, in a time-series graph in another of the operation information display regions, in a case where it is determined, in the determination function, that abnormality has occurred in the outdoor machine or the indoor machine.
