ABSTRACT:
A thermal protection system for a scroll compressor has a temperature sensor which is positioned directly within the discharge passage of the scroll compressor by being directed through an access passageway between the discharge zone and the suction zone of the compressor. The lead wires from the temperature sensor are wired in series with the normal motor temperature sensor circuit to provide the scroll discharge temperature control function as an integral part of the motor temperature control system located within the hermetic shell of the compressor. An additional embodiment of the present invention not only detects discharge gas temperatures but it also has the ability to detect the actual temperature of other selected compressor components.
