PROBLEM TO BE SOLVED: To extend a life time of the body of an absorption cold water warmer and to complete the dilution operation of the absorption cold water warmer in a short time.SOLUTION: In an absorption cold water warmer having an evaporator 11, an absorber 12, a high temperature regenerator 15, and a float valve 21 used for flow control of the liquid circulating through the device, when required the dilution operation, coolant for diluting the concentrated solution in the high temperature regenerator 15 is supplied from the evaporator 11 or the absorber 12 so as to perform the forced dilution operation, the absorption cold water warmer comprises a dilution valve 53a (control means) for controlling drain of the coolant in the dilution piping 54, in which by comparing the pressure on the discharge side of a refrigerant pump 16 with the pressure in the high temperature regenerator 15, if the pressure in the high temperature regenerator 15 is lower, the coolant is drained by the dilution valve 53a (control means) so as to perform the forced dilution operation.SELECTED DRAWING: Figure 1 【課題】吸収冷温水機の希釈運転を短時間で完了させること、及び本体の長寿命化を図ること。【解決手段】蒸発器１１、吸収器１２及び高温再生器１５を備え、機内を循環する液体の流量制御にフロート弁２１を使用し、希釈運転が必要となった場合に、蒸発器１１又は吸収器１２から高温再生器１５内の濃溶液を希釈するための冷媒を供給し、強制希釈運転を行う吸収冷温水機において、希釈配管５４内の冷媒の流出を制御する希釈バルブ５３ａ（制御手段）を備え、冷媒ポンプ１６の吐出側の圧力と高温再生器１５内の圧力とを比較して高温再生器１５内の圧力が低い場合には、希釈バルブ１６（制御手段）によって冷媒を流出させ、強制希釈運転を行う。【選択図】図１
