    Abstract: A compressor system includes a lead compressor operable to produce a flow of compressed fluid at a first output and a lag compressor operable to produce a flow of compressed fluid at a second output. The sum of the first output and the second output defines a system output. A lead variable speed motor is operable to drive the lead compressor at a first compressor speed to vary the first output and a lag variable speed motor is operable to drive the lag compressor at a second compressor speed to vary the second output. A sensor is operable to measure a system load, and a lead motor drive is operable to control the speed of the lead variable speed motor and to set a desired operating state of the lag variable speed motor in response to a comparison of the system load and the system output.

    Abstract: An inverter-integrated or an inverter-separated electric compressor has a control device. The control device estimates a compressor suction pressure based on the temperature of the power element of the inverter, or directly measures the compressor suction pressure by a sensor, or estimates the compressor suction pressure based on a compressor suction temperature or on a compressor housing temperature. Further, the control device calculates a motor torque based on a motor rotational speed, a motor phase current, and a motor phase voltage, estimates a compressor discharge pressure based on the compressor suction pressure and the motor torque, and estimates a compressor discharge temperature based on the compressor suction pressure and the compressor discharge pressure. An electric compressor having a discharge temperature detection means in place of a conventional thermal protector can be realized.

    Abstract: A variable speed drive is provided for operating a compressor motor in a refrigerant system. When a low load situation has been determined by the refrigerant system controls, the variable speed drive operates the compressor motor at lower speed mode of operation. Further, the operation of the variable speed drive is combined with a pulse width modulation control of different system components. In particular, at least one valve or compressor can be can be rapidly cycled by the control to regulate amount of refrigerant passing through the valve or compressor. Example valves would include a shut-off valve for an economizer cycle, an unloader valve, or a suction modulation valve.

    Abstract: A helical screw rotor compressor adapted for working against a pressure container whose pressure P is allowed to vary between a lowest pressure P2 and a highest pressure P1, said compressor being driven by an electric motor. The electric motor is characterised by having in one operating range defined by the pressure interval P of said pressure container a quality such that halving of the torque of said motor will result an increase in motor speed of at least of 6 percent. It is also preferred that the compressor is optimised for an internal volume factor at which the pressure of the compressor will be lower than P2+0.85*(P1−P2) at the opening instance.
