<p>In an air conditioner (10,40,50) having a plurality of valves (30,31,32,33,34) for adjusting the flow of refrigerant circulating in an outdoor unit (11) and an indoor unit (12), and a controller (13,41,51) for controlling the opening degree of each of the valves (30,31,32,33,34) while successively switching the control target value between these valves and a valve control method for the air conditioner, the controller (13,41,51) 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. <IMAGE></p> |
