<p>PURPOSE:To quicken the rise-up of heating capacity and improve comfortable property remarkably, by a method wherein a heater for a heat accumulating body, provided in the ventilating passageway of an indoor unit, is operated before starting the room heating operation of an air-conditioning machine. CONSTITUTION:When room heating operation mode is set by an operating unit 31 and an operation starting time is set, time count is started in an indoor control unit 30. When a time, (t) hours before the operation starting time, has come thereafter, a low voltage is impressed on an electric heater 22 to operate it under a weak output. Then, paraffin in a heat accumulating body 20 is molten gradually and heat is accumulated. When an operation starting time has come, room heating operation is started and the operation of an electric heater 22 is stopped simultaneously. During the room heating operation, indoor air is sucked by the operation of an indoor fan 7 through an air suction port 11 and deprives heat from an indoor heat exchanger 5 and the fins 23 of the heat accumulating body 20 whereby the temperature of the indoor air is increased, thereafter, the indoor air is blown off into a room. Accordingly, the rise-up of heating operation may be quickened and the comfortable property of room heating may be improved.</p> |
