Abstract
Disclosed are a gas compressor and an air conditioning system in which an anomalous temperature rise in an electro-magnetic clutch is detected at an early stage to stop the operation of the gas compressor. A temperature sensor is mounted at a position in the vicinity of a portion of the electro-magnetic clutch which is subject to anomalous heat generation. When there is a rise in the temperature as detected by the temperature sensor, a driving circuit of the electro-magnetic clutch is interrupted before trouble is caused by an abnormally high temperature.
