Turbo chiller
View Patent ↗This turbo chiller includes a shell-and-tube condenser; a header along a length direction of a shell is installed on a refrigerant inlet of the condenser, and openings are formed at least on both end portions of the header in the length direction, which allows high-temperature and high-pressure refrigerant gas from a compressor to be smoothly and evenly distributed to both length-direction end areas in the shell of the condenser through the header.
1. A turbo chiller equipped with a shell-and-tube condenser, and a header placed on top of a shell and along a length direction of the shell is installed on a refrigerant inlet of the condenser, and openings communicated with an inside of the shell are formed at least on both end portions of the header in the length direction, which allows high-temperature and high-pressure refrigerant gas from a compressor to be smoothly and evenly distributed to both length-direction end areas in the shell of the condenser through the header.
2. The turbo chiller according to claim 1 , wherein a guide vane for guiding the high-temperature and high-pressure refrigerant gas flowing from the refrigerant inlet smoothly to the both length-direction end areas is installed in the header.
3. The turbo chiller according to claim 2 , wherein the openings are formed to gradually increase their opening area from a center part to each end part.
4. The turbo chiller according to claim 1 , wherein the openings are formed to gradually increase their opening area from a center part to each end part.
5. The turbo chiller according to claim 1 , wherein
the header is configured to branch to the right and left into duct-like parts extending toward both length-direction ends of the shell, and
the openings are formed on distal-end-side portions of the duct-like parts, respectively.
