摘要： Even when the efficiency of a low temperature heat exchanger is raised to reduce the required heat capacity inputting to the absorption refrigerating machine and the temperature of cooling water supplied to an absorber falls suddenly as it is, and thereby the temperature of a diluted absorbent solution falls suddenly, an absorption refrigerating machine without abnormally increasing the temperature of the concentrated absorbent solution and crystallizing the solution is disclosed. A heat recovery device 8 is provided between a low temperature heat exchanger 6 and a high temperature heat exchanger 7 of an absorbent solution pipe 13 for connecting a high temperature regenerator 1 and an absorber 5 with the low temperature heat exchanger 6, the high temperature heat exchanger 7 and an absorbent solution pump 14 therebetween. Further, the heat recovery device 9 is provided between the low temperature heat exchanger 6 and the absorbent solution pump 14. High temperature and high-pressure vapor is supplied through a heat source fluid supply pipe 10 to a heat exchanger pipe 1A provided within the high temperature generator 1 to thereby heat and boil a diluted absorbent solution within the high temperature regenerator 1 and radiate heat. Then, high temperature drain, which has been condensed by heat radiation and discharged to an exhaust heat fluid pipe 10A, is supplied to the heat recovery devices 8, 9 to thereby heat a diluted absorbent solution delivered from the absorber 5 through the absorbent solution pipe 13 to the high temperature regenerator 1 by an absorbent solution pump 14.

摘要： A dual heat source high-temperature regenerator to solve problems involved in two types of conventional high-temperature regenerators for carrying out heating by using a dedicated burner as the heat source and by using exhaust gas supplied from outside systems as the heat source; namely, the former type has a problem of higher running costs, and the latter a problem of narrower ranges for capacity control. The dual heat source high-temperature regenerator arranges two inner shells and inside an outer shell to form combustion and exhaust gas flues, respectively. The combustion gas flue has a sideways U shape as a whole. The lower end is equipped with a burner, and the upper end connected to an exhaust duct. The exhaust gas flue 62 has a horizontal, straight shape as a whole. One end is provided with an exhaust gas inlet, and the other end connected to an exhaust duct. The portions where a dilute absorbent liquor collects heat easily are the vertical-stroke portion on the sideways U of the combustion gas flue and the vicinity of the end of the exhaust gas flue making the exhaust gas inlet. The vertical-stroke portion and the exhaust gas inlet are collected to the same side so that the convection current of the dilute absorbent liquor produces a smooth circulation of the liquor as shown by broken lines in the drawings.

摘要翻译： 一种双重热源高温再生器，用于解决两种用于通过使用专用燃烧器作为热源进行加热并通过使用从外部系统供应的废气作为热源的常规高温再生器所涉及的问题; 即前者具有运行成本较高的问题，后者是容量控制范围较窄的问题。 双热源高温再生器分别设置两个内壳和外壳内部，形成燃烧和排气烟道。 燃烧气体烟道整体具有侧向U形。 下端配有燃烧器，上端连接到排气管。 废气烟​​道62整体上具有水平的直线形状。 一端设有排气入口，另一端与排气管连接。 稀释吸收剂容易收集的部分是燃烧气体烟道的侧面U上的垂直行程部分和排气进口的废气烟道末端附近。 垂直行程部分和排气入口被收集到同一侧，使得稀释的吸收液体的对流电流产生液体的平滑循环，如图中虚线所示。
