Title:
【発明の名称】冷暖房タイマ
Document Type and Number:
Japanese Patent JP2602932
Kind Code:
B2
Abstract:
PURPOSE:To provide a cooling or heating timer capable of being automatically controlled under all environmental applications by a method wherein means for determining a starting of cooling or heating operation in response to either a surrounding atmosphere temperature and a room temperature and at least one of a thermal capacity of air within a room or a thermal capacity of a wall is provided. CONSTITUTION:CPU 16 may take a thermal capacity CA of a room air, a thermal capacity CW of a wall, a thermal conductivity K1 between the room air and the wall, and a thermal conductivity K2 between the wall and the surrounding atmosphere from a memory 8, input a room temperature T and the surrounding temperature Tout detected by a room temperature detecting means 9 and the surrounding air temperature sensing means 10, take a heating capability QH from a heating capability memory 11, input a calorie Qinw of the room air flowing into the wall and a calorie Qout releasing from the wall into the surrounding atmosphere from the calorie calculating means 13 and 14 and then calculate a time (t) reaching a predetermined room temperature To. A room temperature simulation curve making means 17 may calculate a room temperature T simulation curve 4 in response to the time (t) data, the start time calculation means 18 may calculate a starting of heating operation before the target time (tset) in reference to this curve 4 and then instruct an ON operation means for an air conditioner.
