PROBLEM TO BE SOLVED: To provide an absorption type water cooler/heater capable of easily detecting intrusion of a noncondensable gas in a heating operation. SOLUTION: This absorption water cooler/heater 10 has an absorption refrigerating cycle constituted by connecting a regenerator 12 for heating refrigerant solution, a separator 14, a condenser 18, an evaporator 20, an absorber 22 and a solution circulating pump 24, and has a heating operation mode for heating the load fluid circulated in the evaporator by connecting the separator and the evaporator through a cooling/heating switch valve 30, and guiding the refrigerant vapor generated by the regenerator to the evaporator from the separator by opening the cooling/heating switch valve. Further a detecting means 40 is disposed to detect a condensation temperature Thw of the refrigerant vapor of the evaporator and a condensation temperature Tcon of the refrigerant vapor of the condenser communicated with the evaporator, and detect the intrusion of the noncondensable gas of the evaporator on the basis of the difference between the condensation temperature of the evaporator and the condensation temperature of the condenser in a heating operation.
