WIPO Patent Application WO/2015/015814
Kind Code:
A1
Abstract:
[Problem] To provide an air conditioner that avoids delaying restoring heating operation by way of performing de-icing operation control in accordance with installation conditions. [Solution] An outdoor unit control unit (200) has a de-icing operation condition table (300a) that specifies a de-icing operation interval time (Tm) in accordance with the sum of the rated capacities of indoor units (5a-5c) and the length of refrigerant pipes, which is the length of a liquid pipe (8) or a gas pipe (9). The outdoor unit control unit (200) refers to the de-icing operation condition table (300a) and determines the de-icing operation interval time (Tm) by using the sum of the rated capacities of indoor units (5a-5c) input by an installation information input unit (250). In addition, the outdoor unit control unit (200) forcibly executes de-icing operation if the de-icing operation interval time (Tm) has expired and de-icing operation start conditions have not been met from when the previous de-icing operation finished.
