The present invention relates to a control method for an air conditioner, which prevents a refrigerant from being piled up in an outdoor unit which is not operated during a cooling mode of a multi type air conditioner so that the multi type air conditioner, wherein the multiple outdoor units and indoor units are combined, can maintain stable cooling performance. According to the embodiment of the present invention, the air conditioner forms a cooling cycle capable of cooling and heating operations as the outdoor units and the indoor units are connected to each other by a refrigerant pipe. The control method for an air conditioner includes: a step of starting driving of the indoor units in a cooling operation mode; a step of confirming that the outdoor unit which is not in operation exists among the outdoor units when a set time has passed after the indoor unit starts the operation; a step of determining whether a refrigerant amount on the cooling cycle in operation is insufficient as an indoor expansion valve of an indoor unit in operation is opened more than a set opening; and a step of driving the outdoor unit which is not in operation. |
