After the refrigerant vapor generated when the absorbing liquid is concentrated to the intermediate concentration enters the condenser 14 and is cooled and condensed by the cooling water, the refrigerant liquid (for example, water) enters the evaporator 10 and
The condensed refrigerant water is supplied to the evaporator 10 by the refrigerant pump 38.
Is distributed to the heat transfer tubes (where water is flowing) to obtain cold water. Reference numeral 40 denotes a cooling / heating switching valve, which is closed during the cold water operation. By opening the cooling / heating switching valve 40 and further stopping the supply of the cooling water to the absorber and the condenser, hot water can be obtained instead of the cold water. The control during cooling (chilled water) operation is to detect the chilled water outlet temperature or inlet temperature and adjust the heating flow rate of gas turbine combustion waste heat (for example, waste gas), or to apply a pseudo load to the cooling (chilled water) load. This is done by preventing over-cooling.
