PURPOSE:To simplify control system regulating the driving of a cold water pump and a cooling water pump by a method wherein either one of the amount of discharging flow of a cold water pump, delivering cold water, and a cooling water pump, delivering cooling water, is changed in accordance with the rate of the amount of heating heat in a heating device in absorption refrigerating machine and a water cooler. CONSTITUTION:When an opening degree sensor 11 has detected that the opening degree phiof a heating amount regulating valve 10 is reduced, a sending water amount operating means 14 compares an opening degree signal with an opening degree phi' at a lower control limit flow rate W'. When the opening degree phi is equal to or smaller than the opening degree phi', the flow rate ratio W of a cold water pump 12 to a cooling water pump 13 is determines so as to be a predetermined value of W=0.5 and a control signal (i) at that time becomes (16X0.5+4)mA=12mA. When the control signal is outputted to a cold water pump driving regulating means 15 and a cooling water pump driving regulating means 16, both of the regulating means 15, 16 control the number of rotation of a motor 17, driving the cold water pump 12, or a motor 18, driving the cooling water pump 13, through inverters in accordance with the control signal (i) to restrain the amount of discharging flow in respective pumps.
