LUBRICATION METHOD AND LUBRICATION CONTROLLING APPARATUS FOR CLUTCHLESS COMPRESSOR

摘要

A clutchless compressor is provided with a refrigerant circulation impeding element for substantially impeding the circulation of the refrigerant in an external refrigerant circuit and operates the refrigerant circulation impeding element in response to a refrigerant circulation impeding signal sent from a refrigerant circulation controlling element. The output of the refrigerant circulation impeding command signal from the refrigerant circulation controlling element is stopped during a predetermined period initiated from the activation of a drive source which supplies drive power to the clutchless compressor.
