ABSTRACT:
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 device8is provided between a low temperature heat exchanger6and a high temperature heat exchanger7of an absorbent solution pipe13for connecting a high temperature regenerator1and an absorber5with the low temperature heat exchanger6, the high temperature heat exchanger7and an absorbent solution pump14therebetween. Further, the heat recovery device9is provided between the low temperature heat exchanger6and the absorbent solution pump14. High temperature and high-pressure vapor is supplied through a heat source fluid supply pipe10to a heat exchanger pipe1A provided within the high temperature generator1to thereby heat and boil a diluted absorbent solution within the high temperature regenerator1and radiate heat. Then, high temperature drain, which has been condensed by heat radiation and discharged to an exhaust heat fluid pipe10A, is supplied to the heat recovery devices8, 9to thereby heat a diluted absorbent solution delivered from the absorber5through the absorbent solution pipe13to the high temperature regenerator1by an absorbent solution pump14.
