Abstract

PURPOSE: To provide a heat source system, in which a compressor motor is driven at a high speed and at a variable speed, through the control of an inverter that produces a higher frequency than commercial power source, so as to change refrigerating capacity of the compressor to meet with the load, whereby it is enabled to improve efficiency of operation.
CONSTITUTION: When operating torque Tc of compressor 3 is almost exceeds, for instance, point K1 in the attached graph of characteristic curve, rotational speed of motor 4 is lowered by the function of a first torque controlling circuit 39. On the other hand, when compressor 3 is operated under the condition of point K1 and shaft torque TM of motor 4 takes characteristic curve TM2 in response to the change of speed instruction signal Vs, operating point of compressor 3 is shifted along the broken line shown in the drawing and compressor 3 is operated at point K2 on characteristic curve TM2 for a certain while. Subsequently, operation of compressor 3 is continued at point K3 on the curve TM2, by the function of a second torque controlling circuit 40 and through stabilization of refrigerating cycle. Thus, it is prevented that operating torque becomes excessively large and thus it is enabled to stabilize the operation of compressor system.
