Pressure responsive safety control for refrigerant compressor |
摘要 |
A compressor protector system is an air conditioning system that includes a compressor driven by an engine through an electromagnetic clutch. If the refrigerant charge is below the level necessary for proper compressor cooling and lubrication a pressure or temperature responsive switch cycles at an excessive rate. A digital counter adds the number of cycles occuring over a given time, compares the rate of switch pulses to a predetermined maximum and operates to disengage the clutch and signal the vehicle operator that corrective action to restore the refrigerant charge is required.
