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 deviceis provided between a low temperature heat exchangerand a high temperature heat exchangerof an absorbent solution pipefor connecting a high temperature regeneratorand an absorberwith the low temperature heat exchanger, the high temperature heat exchangerand an absorbent solution pumptherebetween. Further, the heat recovery deviceis provided between the low temperature heat exchangerand the absorbent solution pump. High temperature and high-pressure vapor is supplied through a heat source fluid supply pipeto a heat exchanger pipeA provided within the high temperature generatorto thereby heat and boil a diluted absorbent solution within the high temperature regeneratorand radiate heat. Then, high temperature drain, which has been condensed by heat radiation and discharged to an exhaust heat fluid pipeA, is supplied to the heat recovery devicesto thereby heat a diluted absorbent solution delivered from the absorberthrough the absorbent solution pipeto the high temperature regeneratorby an absorbent solution pump
