63 | SYSTEM AND METHOD OF OPERATION OF MULTIPLE SCREW COMPRESSORS WITH CONTINUOUSLY VARIABLE SPEED TO PROVIDE NOISE CANCELLATION | EP08728166.3 | 2008-01-24 | EP2109717A2 | 2009-10-21 | SCHNETZKA, Harold; EICHELBERGER, E., Curtis, Jr.; NEMIT, Paul, Jr. |
A system for cancelling or attenuating noise in at least two positive displacement compressors proximately located from each other for use with a heating or cooling system. A lead compressor and a lag compressor have a controllable rotational speed and phase of operation. A controller selectably controls the rotational speed and the phase of operation of each of the compressors. The controller controls the rotational speed of the compressors at substantially the same speed for each compressor, with a phase-lock loop and a comparator circuit for each compressor. The controller controls the phase of operation of the compressors through an oscillator so that the lead and lag compressor pressure pulses are spaced between successive outlet pressure pulses to effectively double the combined pulsation frequency for noise attenuation. | ||||||

The compressor system includes a compression device (22; 34) operable between a first speed and a second speed to produce a flow of compressed fluid at a pressure. A blowdown valve (48) is movable between a closed position and an open position in which at least a portion of the flow of compressed fluid passes through the blowdown valve (48) to reduce the pressure of the flow of compressed fluid. A sensor (46) is positioned to measure the pressure and a controller (47) is operable to move the blowdown valve (48) to the open position and set the speed of the compression device (22; 34) to a low set point speed in response to the shutdown signal. |
