Patent ID: 11226127

Abstract:
In a control system, a heat load estimation unit, by referring to location information that indicates a location environment of a house H1 and to weather information that indicates a weather forecast for a certain time slot T1, estimates a heat load which depends on solar radiation to the house H1 during the time slot T1. Specifically, the heat load estimation unit checks whether or not there is a building that blocks the solar radiation to the house H1 during the time slot T1 based on the location information when the weather forecast indicated in the weather information is sunny. Further, the heat load estimation unit estimates the heat load which depends on the solar radiation to the house H1 during the time slot T1 according to a result of the check. An operation control unit controls ahead, operation of an air conditioner provided in the house H1 before the time slot T1 according to the heat load estimated by the heat load estimation unit.
