| A compressor includes a casing, a compression mechanism, a drive shaft, a main frame, a motor, a flow path forming member, and a temperature measuring mechanism. The casing stores lubricating oil in its bottom portion. The main frame has the compression mechanism placed on it and supports the drive shaft in such a way that the drive shaft may freely rotate. The flow path forming member forms an oil flow path at a space adjacent an inner peripheral surface of the casing. The oil flow path carries a flow of lubricating oil, which lubricates sliding portions including the compression mechanism and the drive shaft. The temperature measuring mechanism is disposed outside the casing. The temperature measuring mechanism measures the temperature of a section of an outer peripheral surface of the casing adjacent the oil flow path. | ||||||

| A method and system for detecting and correcting unintended reverse or backward operation of an electric motor driven scroll compressor of a refrigeration system is characterized by monitoring the pressure at a suction side of the compressor during operation of the refrigeration and determining whether the pressure, after a first time interval following startup of the compressor, exceeds and remains in excess of a predetermined upper pressure limit for at least a second time interval. If it does, the compressor is turned off for a third time interval and is then restarted. The foregoing is repeated and if the compressor is turned off a selected number of times because of successive occurrences of high suction side pressures during operation of the refrigeration system in a chilling cycle, an error indication is generated and the refrigeration system is shut down. | ||||||

| 194 | Metering pump with self-calibration and health prediction | US11359191 | 2006-02-22 | US07798781B2 | 2010-09-21 | Douglas A. Parsons; Kevin E. Alstrin |
| A metering pump incorporates a method of relating inner loop current to a pump output pressure. Pump/motor speed, which correlates to current, is measured and controlled by a system controller. System temperature is also measured by the system controller. The controller monitors the measured system temperature and provides for compensation for system losses, including inductive-resistive (IR) losses, and for density and viscosity shifts, within a pre-determined allowable system temperature operating range. An initial system calibration is conducted using a “shut-off” test, where the metering pump is run at a very slow known speed while the system is shut-off. After initial start-up, a health-monitoring feature continues to monitor the current as an indicator of pump performance and continuously adjusts a motor speed to maintain a desired level of pump performance. This provides the system with the ability to compensate for performance losses, including performance losses due to variations in operating conditions, and to compensate for pump wear. | ||||||
