Abstract:
1. An air conditioner, comprising: a vapor compression refrigerant cycle including a compressor for compressing refrigerant, and an interior heat exchanger for adjusting a temperature of air to be blown into a compartment by performing heat exchange between refrigerant circulating in the vapor compression refrigerant cycle and the air to be blown into the compartment; an actual capacity detecting means for detecting an actual capacity of the interior heat exchanger; a target capacity determining means for determining a target capacity of the interior heat exchanger; a first target rotation-speed determining means for determining a first control target rotation speed of the compressor based on a difference between the actual capacity detected by the actual capacity detecting means and the target capacity determined by the target capacity determining means; a changing condition determining means for determining whether a rotation speed of the compressor needs to be changed by a change rate larger than a change rate of the first control target rotation speed, determined by the first target rotation-speed determining means; and a second target rotation-speed determining means for determining a second control target rotation speed that is larger than the first control target rotation speed when the changing condition determining means determines that the rotation speed of the compressor needs to be changed by a change rate larger than the change rate of the first control target rotation speed.
