Patent ID: 7539559

Claim:
A control unit, comprising: a receiving section for receiving user information indicating the state of a user in a first area and temperature data in the first area; a clocking section for clocking a period of time when the user stays in the first area, based on the user information received by the receiving section; a temperature-data recording section for recording the period of time when the user stays in the first area which is clocked by the clocking section, and recording the temperature data received by the receiving section as a temporal change in the temperature of the first area by relating this temperature data to the period of time clocked by the clocking section; a control-information storing section for storing control information for changing the contents of a setting in air-conditioning equipment provided in a second area different from the first area; an execution-time calculating section for, using the period of time when the user stays in the first area, the temporal change in the temperature and a reference temperature that is a predetermined temperature which are recorded in the temperature-data recording section, calculating an execution time to execute a control operation of the air-conditioning equipment based on the control information stored in the control-information storing section; and an operation-data generating section for generating operation data for operating the air-conditioning equipment during the execution time calculated by the execution-time calculating section based on the control information stored in the control-information storing section.
