A sound enclosure of a compressor to attenuate an operational sound level of the compressor is disclosed. The sound enclosure may be configured to generally enclose the compressor and attenuate radiantly emitted sound by the compressor. The sound enclosure may be configured to include a plurality of assembly sections, particularly two side sections and one bottom section, where the two side sections can be joined together like two halves of a clam shell and joined to the bottom section to facilitate easy assembly. The sound enclosure may form openings at longitudinal ends of the sound enclosure to accommodate refrigerant lines. The assembly sections of the sound enclosure may include one or more openings to accommodate a junction box, wire bundles, oil lines, mounting mechanisms, etc.

1. A sound enclosure for a screw compressor in a heating, ventilation, and air conditioning (HVAC) system, comprising: a first side section and a second side section that close in a clam shell configuration, a connection between the first and second side sections extending in a longitudinal direction along a top side of the sound enclosure from a first longitudinal end to a second longitudinal end opposite the first longitudinal end, the first side section and the second side section configured to create a space between the first and second side sections and the screw compressor when the screw compressor is inside the sound enclosure;a bottom section extending in the longitudinal direction of the sound enclosure and configured to create a space between the bottom section and the screw compressor when the screw compressor is inside the sound enclosure, the bottom section including a plurality of apertures to accommodate a mounting mechanism for the screw compressor and to accommodate the mounting mechanism to extend therethrough, wherein the bottom section is configured so that the bottom section does not contact the screw compressor directly; andone or more end plugs that plug or cover the first and second longitudinal ends of the sound enclosure,wherein the sound enclosure is configured to radially surround the screw compressor to impede operational sound emitted radiantly by the screw compressor,wherein the sound enclosure has a length and a height, the length being larger than the height, and the sound enclosure configured to accommodate the screw compressor having a horizontally positioned crankshaft,wherein a variable surface contour of the first side section and a variable surface contour of the second side section are designed to follow a variable profile of the screw compressor, the variable surface contours being configured so that the first side section and the second side section maintain a relatively constant distance from an outline of the variable profile of the screw compressor when installed, andthe bottom section includes a portion extending toward a top side of the screw compressor such that, in a fastened configuration, the first and second side sections are fastened to the bottom section and radially surround the screw compressor, wherein the portion of the bottom section is disposed on an outer side of the first and second side sections. 2. The sound enclosure of claim 1, wherein the first side section, the second side section or the bottom section include at least one opening to accommodate a wire or a refrigerant line that is configured to be connected to the screw compressor. 3. The sound enclosure of claim 1, wherein the sound enclosure has a curved profile from a side view. 4. The sound enclosure of claim 1, wherein the bottom section is configured to have a drainage opening. 5. The sound enclosure of claim 1, wherein an opening is opened through a seam formed by overlap sections of the first and second side sections. 6. The sound enclosure of claim 1, wherein the one or more end plugs are configured to reduce sound emitted from the first and second longitudinal ends of the sound enclosure. 7. The sound enclosure of claim 6, wherein the one or more end plugs are made of a sound impeding material. 8. The sound enclosure of claim 6, wherein the one or more end plugs include an opening configured to accommodate a refrigerant line. 9. The sound enclosure of claim 1, wherein the portion of the bottom section surrounds a perimeter of the sound enclosure. 10. A chiller system, comprising: a screw compressor having a horizontally positioned crankshaft;a sound enclosure configured to radially surround the screw compressor, the sound enclosure having longitudinal end openings and having a length and a height, the length being larger than the height;one or more end plugs that plug or cover the longitudinal end openings; andrefrigerant lines coupled to the screw compressor through the longitudinal end openings;wherein the screw compressor is supported by a mounting mechanism extending through an aperture of a bottom section of the sound enclosure so that the bottom section does not contact the screw compressor directly and a space is maintained between the screw compressor and the bottom section, the bottom section extending in the longitudinal direction of the sound enclosure, andwherein the sound enclosure includes side sections having a variable surface contour designed to follow a variable profile of the screw compressor, the variable surface contour being configured so that the side sections maintain a relatively constant distance from an outline of the variable profile of the screw compressor when installed, and the side sections close in a clam shell configuration, a connection between the first and second side sections extending in a longitudinal direction along a top side of the sound enclosure from a first of the longitudinal end openings to a second of the longitudinal end openings opposite the first, andthe bottom section includes a portion extending toward a top side of the screw compressor such that, in a fastened configuration, the side sections are fastened to the bottom section and radially surround the screw compressor, wherein the portion of the bottom section is disposed on an outer side of the side sections. 11. The chiller system of claim 10, wherein the sound enclosure is configured to impede operational sound radiantly emitted by the screw compressor. 12. The chiller system of claim 10, wherein the mounting mechanism supporting the screw compressor is configured to impede sound transmission between the screw compressor and a supporting beam of the chiller system. 13. The chiller system of claim 10, wherein the bottom section is configured to have a drainage opening. 14. The chiller system of claim 10, wherein the one or more end plugs are configured to reduce sound emitted from the longitudinal end openings of the sound enclosure. 15. The chiller system of claim 14, wherein the one or more end plugs are made of a sound impeding material. 16. The chiller system of claim 14, wherein the one or more end plugs include an opening configured to accommodate a refrigerant line. 17. The chiller system of claim 10, further comprising: a supporting beam, wherein the mounting mechanism is fixed to the supporting beam and the mounting mechanism includes a sound isolator positioned between the screw compressor and the supporting beam. 18. The chiller system of claim 10, wherein the portion of the bottom section surrounds a perimeter of the sound enclosure.
