Abstract:
1. An air conditioner, comprising: a fixed capacity compressor with fixed refrigerant compressing capacity; a variable capacity compressor operated in a loading mode to discharge refrigerant and in an unloading mode to cease to discharge refrigerant, with a refrigerant compressing capacity of the variable capacity compressor varying in response to a duty control signal determining a loading time and an unloading time within a cycle; and a control unit starting the fixed capacity compressor and the variable capacity compressor with a difference in time so as to prevent a synchronous start of said fixed capacity compressor and the variable capacity compressor, wherein the control unit starts the fixed capacity compressor after starting the variable capacity compressor, and during an unloading mode operation of the variable capacity compressor when the control unit is required to start the fixed capacity compressor.
