In accordance with the present invention, the flow rate of the cooled or heated water is adapted to be controlled to correspond to the variation of the energy demand on the load side unit. This can be effected by controlling on the basis of the temperature of the cooled or heated water not only the state of the operation of the heat source, but also the number of revolution of the motor for driving the cooled or heated water pump. | 12-24-2009 |
