Abstract
An absorption refrigerator of excellent thermal efficiency where water vapor contained in the exhaust gas does not condenses even at the starting or during the partial load operation where the temperature elevation is small. A refrigerant drain heat collector 11 allowing the refrigerant liquid condensing by heating the intermediate absorption liquid in the low temperature regenerator 3 and flowing into the condenser 4 to exchange heat with a part of dilute absorption liquid and first and second heat collectors 26, 27 where the exhaust gas discharged from the gas burner 2 and the dilute absorption liquid exchange heat are installed and, at the same time, a absorption liquid pipe (absorption liquid branch pipe) 14 is installed, and a flow control valve 28 is installed in the absorption liquid pipe 14 and, furthermore, a controller 30 is installed in order to control the aperture of the flow control valve 28 so that a temperature sensor 29 continues to detect a predetermined temperature (for instance 100.degree. C.) higher that the dew point temperature of the exhaust gas.
