Abstract: PURPOSE:To obtain a cold water having an invariably specified temp. by a method wherein an absorbing liquid is heated according to load on cold water under feedforward control, PID control is conducted to raise the temp. of the absorbing liquid to the objective value and the flow amount of cooling water is controlled according to the temp. of the cold water at its outlet. CONSTITUTION:The quantity of heat required for heating an absorbing liquid in a regenerator is subjected to feedforward control by a first control means 48 so as to attain the heat quantity corresponding to the load on cold water obtained by multiplying the difference between the outlet temp. 7 and the inlet temp. 40 of the cold water cooled through an evaporator by the flow amount 45 of the cold water. The absorbing liquid is subjected to PID control by a second control means 53 to compensate for the control action of the first control means 48, so that the difference between the absorbing liquid temp. 43 and the objective temp. value produced through an objective value producing circuit 54 will become zero. When the temp. of cold water at its outlet rises, a flow amount control valve 44 for cooling water in the absorber is controlled by a third control means 61, so that the amount of the cooling water will increase. In this way a follow-up control of the load variations takes place rapidly to obtain the cold water having an invariably specified temp.
