    Abstract: A system for the emptying, replenishing and testing of oil maintained within an oil reservoir of a crank case of a compressor unit having an external casing for purposes of housing the compressor motor wherein the interior of the casing is maintained under a positive pressure due to refrigerant entering the casing as it returns from the evaporator. An access valve is disposed on a free end of a conduit having the opposite end thereof disposed in direct access to oil within the oil reservoir. A valve opening structure, when applied to the access valve will position it in an open or flow allowing position, allowing the oil within the casing to pass through the conduit and out through the access valve due to the positive pressure within the casing. The oil may be replaced by securing a liquid pump in fluid communication to the conduit so as to force the access valve open. Upon the pressurized input, from the pump, oil flows back into the oil reservoir against the internal pressure within the casing.

    Abstract: An apparatus for detecting an oil level and a method for controlling the same, an apparatus for detecting oil flow and a method for controlling the same, and a method for controlling oil return using the detected oil level and the detected oil flow are disclosed. The level of oil stored in a compressor is measured at two or more positions. The frequency comparison scheme using two electrodes can correctly detect the level of oil stored in the compressor, a refrigerant state, and the level of mixed oils, and can determine an internal state of the compressor and a normal or abnormal state of the oil return system, such that the oil return control can be actively controlled. The flow of oil in the oil return pipe is detected so as to determine whether the oil is normally supplied in real time, such that a malfunction of the compressor is prevented and a valve state can be checked. The level of oil stored in the compressor is adjusted not only using the oil level detection result but also the oil flow detection result, and the oil return operation can be controlled.

    Abstract: Disclosed is a compressor capable of having an enhanced performance by sufficiently supplying oil to components where sliding occurs not only in a high speed driving mode but also in a low speed driving mode. The compressor may increase an oil supply amount in a low speed driving mode, but may restrict an oil supply amount when a rotation speed of a driving motor reaches a predetermined speed in a constant or high speed driving mode, by setting the number of turns of an external groove to be approximately 1.75, and by forming an oil feeder in a conical shape.

    Abstract: A compressor controller provides integrated monitoring, control, and alarm capabilities. The compressor controller receives a run signal from a rack controller. Upon receipt of the run signal, the compressor controller monitors startup conditions to determine whether it is safe to start the compressor. If so, the compressor controller applies power to the compressor and determines whether the compressor is running properly. Once the compressor is running properly, the compressor controller continues to monitor the operation of the compressor. If the compressor controller detects a fault conditions during the startup or operation of the compressor, the compressor controller provides an alarm signal and shuts down the compressor if necessary. The compressor controller provides maximum protection for the compressor by monitoring a plurality of relevant conditions and by shutting the compressor down when necessary. The compressor controller also maximizes the compressor's availability by evaluating the monitored conditions to determine whether the compressor can continue to run or be restarted despite a fault condition.
