PROBLEM TO BE SOLVED: To allow a user to check overuse for saving, and at the same time to contribute to saving resources by integrating measured power consumption and unit power rates for obtaining power rates, and by indicating the obtained power rates. SOLUTION: In an air-conditioning equipment body 1, power being consumed by the air-conditioning equipment body 1 is measured at each fixed time, power consumption being measured by a measurement operation means and rates per unit power are integrated for obtaining power rates, and the power rates are integrated. Then, the air-conditioning equipment body 1 converts an integration value to transmission data at each fixed time for sending to a remote controller 2. The remote controller 2 displays the power consumption being obtained according to reception data or the power consumption being obtained according to the reception data, or the power rates being obtained by the reception data. In this manner, the power consumption or the integration value of the power rates from the time when a measurement starting button is pressed to present time is indicated on a display 23, thus allowing a user to save electric power using the integration value as standards for saving energy. |
