Abstract
Noise reduction in a screw compressor based refrigeration system is achieved by the use of multiple compressor discharge and/or suction lines. The lines are configured and/or fabricated from materials which reduce system noise which would otherwise be induced by vibration as well as the system noise associated with gas pulse energy in the discharge gas stream flowing from the compressor.
Claims21
A refrigeration system comprising:
- a condenser;
- a metering device connected to said condenser;
- an evaporator connected to said metering device;
- a screw compressor, said screw compressor defining a suction area and a discharge passage;
- and
- multiple flow lines connecting at least one of said suction area and said discharge passage of said compressor to at least one of said condenser and said evaporator.
3 more elements
A method for reducing noise in screw compressor-based refrigeration systems comprising the steps of:
- compressing refrigerant gas from a suction to a discharge pressure in said compressor;
- flowing gas at said discharge pressure from said compressor through at least two discharge flow paths;
- and
- recombining the flow of gas passing through said multiple flow paths at a location where the gas pulse energy in the gas flowing through the individual ones of the multiple flow paths is out of phase so that the recombination thereof causes a cancellation of such energy and a reduction of the noise generated by said system.
