Three functions absorption type refrigerating apparatus

PROBLEM TO BE SOLVED: To make simplified, reduced in cost and improvable in reliability the dilute solution supply flow quantity control such as the control of the revolution speed of a solution pump to prevent fluctuation of a liquid level in a high-temperature re-generator or the like. SOLUTION: This triple effect absorption refrigerating device is provided with a condenser 3, an absorber 2, an evaporator 1, three re-generators 4, 5 and 6 of high-temperature, middle-temperature and low-temperature, and three solution heat exchangers 7, 8 and 9, and it is constituted so that absorbed liquid from the absorber 2 is supplied to, at least, the high-temperature re-generator 4 and the middle-temperature re-generator 5 through a solution pump 26, and refrigerant steam generated in the high-temperature side re-generators 4 and 5 is led into the low-temperature side re-generators 5 and 6 in order, and used as a heating source of the low-temperature side re-generators 5 and 6. The dilute solution inlet of the middle-temperature re-generator 5 is provided with a dilute solution flow-in quantity control means to separately control a liquid level of the middle-temperature re-generator 5 from a liquid level of the high-temperature re-generator 4.
