Abstract
A variable displacement type compressor circulates a refrigerant in an air conditioning circuit. The compressor has a compression mechanism and a displacement controller. The compression mechanism compresses and discharges the refrigerant. The displacement controller controls the discharge amount of the refrigerant of the compressor. The displacement controller further includes a normal control means and a protective control means. The normal control means controls the displacement based on a cooling load. The protective control means controls the displacement based on the value in connection with the rotational speed of the compressor and the actual operating information of the compressor.
