To increase exhaust heat recovery efficiency of an exhaust heat utilization type absorption refrigeration device as much as possible, and to reduce a size of a heat exchanger part.
This absorption refrigeration device includes a high temperature regenerator 1, a high temperature solution heat exchanger 2, a low temperature solution heat exchanger 3, a low temperature regenerator 8, a condenser 9, an absorber 4, and an evaporator 10 or the like. Exhaust heat of a part of a medium temperature solution in a dilute solution circulated from the absorber 4 to the high temperature regenerator 1 is recovered efficiently while the dilute solution is forcibly circulated by an exhaust heat recovering device having a dilute solution circulating means 14b, and is supplied to the low temperature regenerator 8 or the high temperature regenerator 1. Thereby, the exhaust heat recovery efficiency is improved, and a circulating amount of the dilute solution to the high temperature regenerator 1 is reduced to increase the efficiency.
