Zusammenfassung:An absorption chiller having a high temperature generator and a low temperature generator includes a pressure detecting means for detecting a pressure within the high temperature generator, a concentration fixing control means for controlling a concentration of the solution of the high temperature generator or of the low temperature generator, a selection converter for receiving two output signals from the pressure detecting means and the concentration fixing control means as inputs, selecting and outputting a higher one of these input signals, and a rotational speed controlling device for controlling a rotational speed of the solution pump by the output signal of this selection converter. An absorption solution is controlled adequately in its circulation quantity in accordance with a load from a low load range to a high load range of this absorption chiller, so that the solution is not crystallized even in the low load range, and efficiency during a partial load operation is improved.
