Abstract
In an air conditioner having a plurality of valves for adjusting the flow of refrigerant circulating in an outdoor unit and an indoor unit, and a controller for controlling the opening degree of each of the valves while successively switching the control target value between these valves and a valve control method for the air conditioner, the controller judges whether the opening degree of a currently-operated (controlled) valve which is currently being subjected to the opening degree control operation is coincident with a target value. If the opening degree of the valve reaches the target value even within a predetermined one-operation time set for the valve, the control target valve is immediately switched to a next valve. Further, if the opening degree of the valve does not reach the target valve even after the predetermined one-operation time, the one-operation time is extended to continue the opening degree control operation on the currently-operated valve.
