PROBLEM TO BE SOLVED: To provide an absorption water cooling-heating machine whose performance deterioration is suppressed by preventing outflow of uncondensed refrigerant vapor through a channel of condensed liquid refrigerant from a heating tube of a low temperature regenerator to a condenser. SOLUTION: An evaporator 10, an absorber 20, a high temperature regenerator 30, the low temperature regenerator 40 and the condenser 50 are connected together to constitute a refrigerating cycle. The heat of condensation of refrigerant vapor generated in the high temperature regenerator 30 is used to heat the low temperature regenerator 40 in order to regenerate refrigerant vapor. In this double effect absorption water cooling-heating machine, a variable resistance restrictor 48 is provided at the outlet channel, between the low temperature regenerator 40 and the condenser 50, through which the liquid refrigerant used for heating the low temperature regenerator 40 flows.
