Abstract
A method for controlling the displacement changing mechanism of a variable displacement wobble plate type compressor arranged in a car air-conditioning circuit is carried out in a manner such that, when the operating condition of the compressor is stable and when hunting of a controlled variable of the air-conditioner, i.e., hunting of a temperature at the outlet end of an evaporator of the air-conditioning circuit, occurs, a manipulated variable to be given to the displacement changing mechanism to cause a change in the controlled variable is reduced so that hunting of the controlled variable is suppressed and the controlled variable reaches a desired value.
