Abstract: The present invention provides a high-efficiency absorption refrigerating machine which can recover heat from a heat source and can efficiently recover heat from an internal cycle. The absorption refrigerating machine includes an evaporator, an absorber (A), a condenser (C), a high-temperature regenerator (GH), a low-temperature regenerator (GL), a low-temperature solution heat exchanger (LX), and solution paths and refrigerant paths by which these units are connected. The absorption refrigerating machine further comprises two branch solution paths branched from a solution supply path through which a dilute solution is introduced from the absorption (A) to the high-temperature regenerator (GH). On one of the branch solution paths, there is disposed a drain heat exchanger (DX) operable to perform heat exchange between the dilute solution in the branch solution path and an exhaust heat source which has heated the high-temperature regenerator (GH). On the other of the branch solution paths, there are disposed a first high-temperature solution heat exchanger (HX1) and a second high-temperature solution heat exchanger (HX2) operable to perform heat exchange between the dilute solution in the branch solution path and a concentrated solution heated and concentrated in the high-temperature regenerator (GH). The absorption refrigerating machine is configured such that the dilute solution flows through the first high-temperature solution heat exchanger (HX1) and the second high-temperature solution heat exchanger (HX2) in this order, and the concentrated solution discharged from the high-temperature regenerator flows through the second high-temperature solution heat exchanger (HX2) and the first high-temperature solution heat exchanger (HX1) in this order.

Abstract: PROBLEM TO BE SOLVED: To provide an absorption heat pump capable of reducing the amount of a refrigerant led out of a machine during bleeding. SOLUTION: The absorption heat pump 1 extracts non-condensable gas Ng from inside of a condenser 40 to a bleed tank 62 via a first bleed flow passage 64 by pressure-feeding a solution S to the bleed tank 62 by a bleed solution pump 36. By preventing a backflow of fluid by a bleed backflow prevention vale 64v, shutting off a return solution flow passage 67 by a return solution shut-off valve 67v, and pressure-feeding the solution S to the bleed tank 62 by the bleed solution pump 36, the pressure of the non-condensable gas Ng in the bleed tank 62 is increased and the non-condensable gas Ng collected in the bleed tank 62 is led out from a delivery port 62h. Due to increase in the pressure within the bleed tank 62, vapor of a refrigerant V collected in the bleed tank 62 accompanying the non-condensable gas Ng is condensed and absorbed in the solution S in the bleed tank 62, so that the amount of the vapor of the refrigerant V to be led out of the machine is reduced.
