Exhaust gas-driven absorption water cooling and warming machine

Abstract

An absorption water cooling and warming machine comprises: an absorber; a low-temperature generator; an exhaust heat recovery generator; a high-temperature generator; a refrigerator; an evaporator; liquor path and refrigerant path for connecting the absorber, low-temperature generator, exhaust heat recovery generator, high-temperature generator, refrigerator and the evaporator; exhaust gas path for guiding the high-temperature exhaust gas into the high-temperature generator and then guiding to exhaust heat recovery generator. The liquor path includes the path for making the diluted liquor flowing from the absorber diffluent and flows respectively into the high-temperature generator and the exhaust heat recovery generator, and the path for making the diluted liquor that have been heated and condensed to medium concentration by the high-temperature exhaust gas in the high-temperature generator flows into the low-temperature generator from the high-temperature generator. The liquor with medium concentration guided into the low-temperature generator is heated and condensed by the refrigerant steam that generated in the high-temperature generator and used as hot source, the diluted liquor guided into the exhaust heat recovery generator is heated and condensed by the exhaust gas that flows through the high-temperature generator.

Description

[0001] This application is a divisional application of an invention patent application with an application date of July 9, 2002, an application number of 02141199.9, and an invention title of "absorption cold and hot water machine". technical field [0002] The present invention relates to an absorption type cold and hot water machine, especially such an absorption type cold and hot water machine, which is driven by exhaust gas and can effectively utilize high temperature exhaust gas discharged from external devices such as gas turbines to improve the utilization efficiency of exhaust gas , and it can be compact. Background technique [0003] In the case where the absorption chiller is driven by high-temperature exhaust gas at a temperature of 200 to 400°C, it is known that when the absorption chiller performs air cooling operation, the high-temperature exhaust gas will be used in double-effect, while the exhaust gas After the temperature is lowered, the exhaust gas will be ...

AI Technical Summary

Problems solved by technology

[0010] In the absorption chiller and hot water machine disclosed in Japanese Patent Document No. 53-20543, if the exhaust gas path is extended in a complicated manner, it is difficult for the absorption chiller to be constructed more compactly

[0011] In addition, the gas-liquid separation in waste heat recovery generators usually requires a lot of space, so the size of the gas-liquid separator constitutes an obstacle in the waste gas path arrangement
