Document Type and Number:
WIPO Patent Application WO/2019/193714
Kind Code:
This air conditioner comprises: an intake temperature sensing unit that senses, as an intake temperature, the temperature of air drawn into a heat exchange unit, or the temperature of a space in which heat exchanging is to be performed; a cooling/heating temperature sensing unit that senses the temperature of the air blown out from the heat exchange unit, or the temperature of the heat exchange unit, as a cooling/heating temperature; and a control device that acquires at different points in time the difference in temperature between the intake temperature sensed by the intake temperature sensing unit and the cooling/heating temperature sensed by the cooling/heating temperature sensing unit, and determines whether the heat exchange unit is fouled on the basis of a temporal sequence pertaining to the acquired difference in temperature.
