Abstract: A hermetic electric compressor includes a motor unit having a stator coil and a compressor unit driven by the motor unit for compressing refrigerant gas. A temperature sensor is provided at the stator coil for monitoring a temperature of the stator coil. A control unit is further provided to control a rotational frequency or speed of the motor unit via the stator coil depending on the monitored temperature of the stator coil. The temperature sensor and the control unit are connected via a shielded cable or a twisted pair. The shielded cable or the twisted pair may be grounded via a capacitor. Further, a thermostat may also be provided at the stator coil and connected in series to the temperature sensor.

Abstract: A compressor may include a shell, a compression mechanism, first and second temperature sensors, and a control module. The shell may define a lubricant sump. The compression mechanism may be disposed within the shell and may be operable to compress a working fluid. The first temperature sensor may be at least partially disposed within the shell at a first position. The second temperature sensor may be at least partially disposed within the shell at a second position that is vertically higher than the first position. The control module may be in communication with the first and second temperature sensors and the pressure sensor and may determine whether a liquid level in the lubricant sump is below a predetermined level based on data received from the first and second temperature sensors.

Abstract: Process for regulating a compressor with motor for a refrigerating system, where the temperature of the cooling site is regulated through an on-off motor mode if the temperature in the compressor exceeds an upper temperature threshold. In addition, the temperature of the cooling site is regulated through a continuous on mode of the motor as soon as the motor has cooled to a lower temperature threshold. The controller converts a variable corresponding to the cooling requirement of the cooling site into a switch signal for a valve, which results in clocked opening and closing of the valve, or uses a frequency converter, which controls the cooling liquid flow through the compressor by regulating the voltage and the frequency of the motor in that the frequency converter converts a variable corresponding to the cooling requirement of a cooling site into a voltage and a frequency for the motor.

Abstract: A temperature management system for an air compressor includes a plurality of cooling fans coupled to an intercooler of the air compressor; an electrical relay comprising a coil and contacts operated by the coil; and a temperature switch coupled to the coil of the electrical relay. The contacts are located between the cooling fans and an electrical power supply. The temperature switch opens at a temperature above a predetermined temperature at a high pressure inlet of a high pressure stage of the air compressor, thereby closing the contacts of the electrical relay which applies power to the cooling fans.

Abstract: An apparatus controls a variable displacement compressor used in a refrigerant circuit. The compressor includes a drive shaft, which is rotated by an engine. When the drive shaft rotates, the compressor compresses refrigerant sent from the external refrigerant circuit and discharges the compressed refrigerant to an external refrigerant circuit. When the displacement of the compressor is minimized, the circulation of refrigerant in the refrigerant circuit is stopped. The apparatus has a control mechanism for varying the pressure in the crank chamber. A detector detects a physical quantity that reflects the heating status of the compressor. When the compressor displacement is minimized and the quantity detected by the detector indicates that the heating status of the compressor is deteriorating, a controller commands the control mechanism such that the displacement of the compressor is greater than the minimum displacement.
