<p><P>PROBLEM TO BE SOLVED: To provide a heat pump system capable of properly carrying out operation control of a hot water supply portion. <P>SOLUTION: The heat pump system 1 is equipped with a heat source unit 2, the first utilization unit 4a, the second utilization units 10a, 10b, temperature sensors 107a, 107b, and a control part 116a. The first utilization unit 4a has a first utilization side heat exchanger 41a connected to the heat source unit 2 and carrying out heat exchange of a coolant and a water medium. The second utilization units 10a, 10b have second utilization side heat exchangers 101a, 101b connected to the heat source unit 2 and carrying out heat exchange of the coolant and an air medium. The temperature sensors 107a, 107b are provided in the second utilization units 10a, 10b to detect a temperature Tr in an air conditioning object space sq. The control part 116a controls on and off of operation of the first utilization unit 4a on the basis of the detection results of the temperature sensors 107a, 107b and a target set temperature To of the second utilization unit 10a. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
