Definitions
- This invention relates to oil separators for use in refrigeration and cooling systems, and, in particular, to methods and apparatus for reducing the noise levels outputted by an oil separator that is located within a refrigeration or cooling system.
- a water cooled chiller type refrigeration system 10 using a screw compressor 20 typically includes a condenser 30, a cooler 40, an oil separator 50, a condenser fan 60 and one or more expansion devices 70.
- the compressor 20 requires oil for lubrication, wherein the oil is typically entrained in a refrigerant.
- the combined oil and refrigerant mixture is carried through a compression cycle and discharged into the oil separator 50, where the oil must be removed from the refrigerant to allow for proper operation of the cooler 40. From the oil separator 50, the clean refrigerant flows to the condenser 30 and the separated oil is returned to the compressor 10.
- the present invention provides a muffling apparatus and methods for using the muffling apparatus to reduce the noise level output of an oil separator within a refrigeration or cooling system.
- the muffling apparatus of the present invention has a first, muffling segment and a second, non-muffling segment and is placed within an internal area of an oil separator.
- the muffling segment of the muffling apparatus is at least partially formed of an absorbing material.
- the absorbing material is effective to attenuate the energy of pressure waves/pulsations from the compressor into heat, thus reducing the resultant vibrations of (and, in turn, noise levels outpurted from) the oil separator caused by energy from the waves/pulsations.
- the muffling segment is comprised of a tubular body that includes an external shell, wherein the external shell surrounds an internal layer and wherein the internal layer surrounds an internal shell.
- the muffling segment also has a first end, a second end and a lumen therebetween, wherein the lumen is surrounded by the internal shell of the muffling segment.
- the internal layer of the muffling segment of the muffling apparatus is made of the absorbing material, and the internal shell has a plurality of perforations/openings defined therein.
- Each opening provides a direct fluid/air pathway from the lumen to the internal layer of absorbing material.
- the purpose of the openings is to enable the pressure waves/pulsations that propagate through the lumen of the muffling segment to come into contact with the internal layer of absorbing material, thus enabling the absorbing material to attenuate the pressure waves/pulsations.
- the non- muffling segment of the muffling apparatus has a tubular body, wherein the first end of the non-muffling segment is connected to the second end of the muffling segment and the second end of the non-muffling segment is connected to an internal area of an oil separator.
- the muffling apparatus has a non-straight shape, such as a bent shape or a curved shape, wherein the bent or curved portion(s) of the non-straight muffling apparatus are part of the non-muffling segment.
- FIG. 1 is a schematic view of a known exemplary arrangement of a refrigeration/cooling system utilizing an oil separator.
- FIG. 2 is a perspective view of an exemplary embodiment of an oil separator muffling apparatus in accordance with the present invention
- FIG. 3 is a side, cross-sectional view of the muffling apparatus of
- FIG. 2 taken along line 3-3 of FIG. 2;
- FIG. 4 is a perspective view, with partial cut away, of an exemplary oil separator wherein the muffling apparatus of FIGS. 2 and 3 has been placed within an internal area thereof.
- the present invention provides a muffling apparatus and methods of using the apparatus to reduce the noise level output produced by an oil separator of a refrigeration or cooling system, such as a water-cooled chiller type refrigeration system.
- the muffling apparatus of the present invention is placed within an oil separator in order to attenuate pressure waves/pulsations that emanate from the compressor of the refrigeration system.
- pressure waves/pulsations are believed to be responsible for creating vibrational forces that cause the oil separator surface to vibrate and, in turn, to disadvantageously generate high noise levels in its vicinity.
- Attenuation occurs during use of the muffling apparatus of the present invention because the pressure waves/pulsations come into contact with an absorbing material located within a muffling segment of the muffling apparatus.
- the absorbing material attenuates the energy of the pressure waves/pulsations into heat and thus reduces the resultant vibrations of (and, in turn, noise levels outputted from) the oil separator that are caused by energy from the pressure waves/pulsations.
- the muffling apparatus of the present invention has many benefits.
- FIGS. 2 and 3 depict an exemplary oil separator muffling apparatus
- the muffling apparatus 100 has at least two segments, wherein each segment serves a different purpose in accordance with the present invention and is made of different materials or material combinations than the other segment(s).
- the segments are connected to each other as is known in the art, e.g., by welding, brazing and/or through the use of rivets.
- a muffling apparatus 100 of the present invention has a first, muffling segment 1010 and a second, non-muffling segment 1020.
- the muffling segment 1010 has a tubular body comprised of an external shell 110 that surrounds an internal layer 120, wherein the internal layer has an internal shell 130 - that is, the external shell and the internal shell "sandwich" the internal layer.
- the number and arrangement of the shells 110, 130 and the internal layer 120 of the muffling segment 1010 to be as shown in FIGS. 2 and 3, it is also within the scope of the present invention for the muffling segment to be comprised of more or fewer layers and/or more or fewer shells than are depicted in the Figures, and/or for the layer(s) and/or the shell(s) to have a different arrangement than that which is shown.
- the muffling segment 1010 has a first end 140, a second end 150 and a lumen 160 therebetween, wherein the lumen is surrounded by the internal shell 130.
- the second end 150 of the muffling segment 1010 is adapted for connection to a first end 1100 of the non-muffling segment 1020 by techniques known in the art, e.g., welding, brazing and/or through the use of rivets.
- the purpose of the muffling segment 1010 is to reduce the noise level output of an oil separator in which the muffling apparatus 100 is placed.
- at least one of the external shell 110, the internal layer 120 and the internal shell 130 of the muffling segment 1010 should be made, at least partially, of a material that will absorb the energy from pressure waves (that emanate from the compressor and are transferred to the oil separator) and dissipate/attenuate that energy into absorbable heat.
- the internal layer 120 of the muffling segment 1010 is made of such an absorbing material.
- the absorbing material is a fiberglass material.
- a currently preferred fiberglass material is comprised of glass fibers with a phenolic resin, wherein the material has a density in the range of about 86 kg/m 3 to about 105 kg/m 3 and a maximum temperature of about 177°C.
- the material(s) from which the external shell 110 and the internal shell 130 of the muffling segment 1010 are constructed should be strong and durable, yet inexpensive.
- the external shell 1 10 and the internal shell 130 can be constructed of different or identical materials; however, according to an exemplary embodiment of the present invention, both the external shell 110 and the internal shell 130 are constructed of a sheet metal material.
- a currently preferred sheet metal material is steel, but other metal-based materials can be utilized as well.
- the internal shell 130 of the muffling segment 1010 has a plurality of perforations or openings 170 defined therein. Each opening 170 provides direct fluid communication between the lumen 160 and the internal layer 120 of absorbing material.
- the purpose of the openings 170 is to enable the pressure waves/pulsations that are propagating/passing through the lumen 160 of the muffling segment 1010 to come into contact with the internal layer 120 of absorbing material, thus enabling the absorbing material to attenuate the pressure waves/pulsations.
- openings 170 can vary depending on several factors, including, but not limited to, the frequency of the pressure waves/pulsations that are expected to be encountered. According to a currently preferred embodiment of the present invention, openings 170 are defined in a range of about 10% to about 50% of the overall surface area of the internal shell 130. Moreover, although the openings 170 can have any shape and any spacing interval, it is currently preferred for the openings to be substantially round and spaced apart from each other at substantially identical distances, as best shown in FIG. 3.
- the non-muffling segment 1020 of the muffling apparatus 100 also has a tubular body, and has first and second ends 1100, 1200.
- the first end 1100 of the non-muffling segment is connected to the second end 150 of the muffling segment 1010, and the second end 1200 of the muffling segment is connected to an internal area 510 of an oil separator 500, as shown in FIG. 4.
- Such connections are made as is generally known in the art, e.g., via welding, brazing and/or through the use of rivets.
- the non-muffling segment 1020 of the muffling apparatus can have more than one layer and can be made of more than one material, it is currently preferred to form the non-muffling segment of one layer and one material, wherein suitable materials include sheet metal materials such as steel.
- suitable materials include sheet metal materials such as steel.
- cost savings occurs because sheet metal material is less expensive to purchase as compared to the absorbing material used in the muffling segment 1010.
- design flexibility because one can purchase many different pre-formed shapes and sizes of the sheet metal material from which the non-muffling segment 1020 is formed.
- the size and shape of muffling apparatus 100 also can vary; however, it is currently preferred for muffling apparatus 100 to have a non-straight overall shape.
- FIGS. 2 and 3 depict a muffling apparatus that has a curved shape.
- the non-straight shape of muffling apparatus 100 is preferred because it enables the apparatus to have a larger size (as compared to an apparatus with a straight shape) while still fitting within the space confines of an oil separator. That allows for a longer lumen 160 to be defined between the first and second ends 140, 150 of a the muffling segment 1010, thus providing added opportunities for pressure waves/pulsations to come into contact with the internal layer 120 via openings 170.
- FIGS. 1 As shown in FIGS.
- muffling segment 1010 of muffling apparatus 100 has a substantially straight shape and non- muffling segment 1020 has a curved shape.
- Such an arrangement is advantageous because a cost savings is achieved by not forming the muffling apparatus entirely of the muffling segment materials, yet the muffling apparatus is still capable of providing significant noise reduction, as will be discussed in more detail below.
- support element 600 is attached (e.g., by welding) to the first end 150 of the muffling segment 1010 and to the internal area 510 of the oil separator 500. The presence of the support element 600 provides added support to muffling apparatus 100 by bearing the weight of muffling segment 1010.
- Support element 600 can be made of a variety of materials, including, but not limited, to one or more metal-based materials (e.g., steel).
- the size of the muffling apparatus 100 can vary depending on several factors, most notably the size of the oil separator in which the muffling apparatus is installed. It is currently preferred for the size of the muffling apparatus 100 to vary proportionally with the size of the oil separator.
- the muffling apparatus 100 will have a different predetermined size in order to fit within a 14 inch oil separator than it would to fit within a 16 inch oil separator or an 18 inch oil separator, wherein the size of the muffling apparatus for a 16 inch oil separator generally will be approximately 16/14 times the size of the muffling apparatus for a 14 inch oil separator and approximately 16/18 times the size of the muffling apparatus for an 18 inch oil separator.
- the effective height, H (see FIG. 3), occupied by the muffling apparatus is in the range of about 7.5 inches to about 9.5 inches, with an effective height of about 8.5 inches being currently preferred, and the effective length, L (see FIG. 3) occupied by the muffling apparatus is in the range of about 11 inches to about 13.5 inches, with an effective height of about 13.2 inches being currently preferred.
- these measurements would be approximately 16/14 times those for the 14 inch oil separator, and for placement within an 18 inch oil separator, they would be approximately 18/14 times those for the 14 inch oil separator.
- the length of muffling segment 1010 also can vary according to several factors, including the frequency of the pressure waves expected to the encountered within the oil separator. For example, the length of muffling segment 1010 can be comparatively greater when the frequency of the pressure waves is expected to be about 2000Hz versus 125Hz. According to an exemplary embodiment of the present invention in which muffling apparatus 100 is placed within a 14 inch oil separator, the length of the muffling segment 1010 is about 4.5 inches to about 6.5 inches, wherein a length of about 6 inches is currently preferred. Stated differently, the length of muffling segment 1010 generally comprises about 30% to about 60% of the overall length, L, of the muffling apparatus 100.
- the Global dBA of -4 dBA also supports that there was an acoustic reduction, and that the dominant frequency band of the pressure waves/pulsations was in the range of about 500-1000Hz.
- the results in Table I are very favorable.
- noise reduction levels were observed for each of the six selected pressure wave frequency bands. This is important because different compressors operate at different dominant pressure output levels, and thus would produce different Global dBA measurements.
- noise reduction occurred despite the fact that the muffling apparatus was only partially formed of a muffling segment 1010. This signifies that by forming the muffling apparatus from a muffling segment 1010 and a non-muffling segment 1020, one can achieve noise reduction while enjoying cost savings and design flexibility.
- a muffling apparatus 100 of the type shown in FIGS. 2 and 3 can be installed in an oil separator with confidence that the noise level reduction will be at least IdB, with a noise reduction level of up to 12 dB being possible as well depending on the dominant frequency band of the pressure/wave pulsations emanating from the compressor.
