Abstract
Disclosed is a muffler for a water-cooled chiller or air-cooled of a vapor-compression or absorption refrigeration system, the muffler having: an upstream case (110) having a fluid inlet (120); a downstream case (115) connected to the upstream case at a downstream end of the upstream case, the downstream case having a fluid outlet (125); the upstream case having a plurality of axially adjacent outer muffler rings (145) and a plurality of axially adjacent inner muffler rings (155), the outer muffler rings being axially coextensive and a radially exterior to the inner muffler rings and defining a fluid inlet passage (140) therebetween, wherein the outer muffler rings and inner muffler rings are a metal mesh material.
Claims18
A muffler for a chiller of a vapor-compression or absorption refrigeration system, the muffler comprising:
- an upstream case having a fluid inlet;
- a downstream case connected to the upstream case at a downstream end of the upstream case, the downstream case having a fluid outlet;
- the upstream case having a plurality of axially adjacent outer muffler rings and a plurality of axially adjacent inner muffler rings, the outer muffler rings being axially coextensive and a radially exterior to the inner muffler rings and defining a fluid inlet passage therebetween, wherein the outer muffler rings and inner muffler rings are a metal mesh material,
- wherein the upstream case is a primary upstream case and the muffler includes a secondary upstream case fluidly connected to the primary upstream case proximate a downstream end of the primary upstream case, the secondary upstream case including a plurality of axially adjacent muffler rings that are a metal mesh material.
A system comprising:
- a chiller comprising a muffler, the muffler comprising:
- an upstream case having a fluid inlet;
- a downstream case connected to the upstream case at a downstream end of the upstream case, the downstream case having a fluid outlet;
- and
- the upstream case having a plurality of axially adjacent outer muffler rings and a plurality of axially adjacent inner muffler rings, the outer muffler rings being axially coextensive and a radially exterior to the inner muffler rings and defining a fluid inlet passage therebetween, wherein the outer muffler rings and inner muffler rings are a metal mesh material,
- wherein secondary upstream case fluidly connected to the primary upstream case proximate a downstream end of the primary upstream case, the secondary upstream case including a plurality of axially adjacent muffler rings that are a metal mesh material.
A method of operating a chiller system, the chiller system comprising a muffler,
- the muffler further comprising:
- an upstream case having a fluid inlet,
- a downstream case connected to the upstream case at a downstream end of the upstream case, the downstream case having a fluid outlet,
- the upstream case having a plurality of axially adjacent outer muffler rings and a plurality of axially adjacent inner muffler rings, the outer muffler rings being axially coextensive and a radially exterior to the inner muffler rings and defining a fluid inlet passage therebetween, and wherein the outer muffler rings and inner muffler rings are a metal mesh material,
- wherein the upstream case is a primary upstream case and the muffler includes a secondary upstream case fluidly connected to the primary upstream case proximate a downstream end of the primary upstream case, the secondary upstream case including a plurality of axially adjacent muffler rings that are a metal mesh material,
- the method comprising:
- muffling noise so that over an octave band of 80 Hz to 130 Hz, a sound pressure level is between approximately 78 dBA-Wtg and approximately 80 dBA-Wtg.
