Abstract
A heat pump system has a single heat source unit connected to at least one load unit to heat water to a high temperature. A hot water supply system(heat pump system) includes a heat source unitprovided with a first compressor, a four-way selector valveand a heat source heat exchanger, and a load unitprovided with a first flow controller, a first load heat exchanger, a second compressor, a second load heat exchanger, and a second flow controller. A main circuit A is formed by connecting the first compressor, the four-way selector valve, the heat source heat exchanger, the first flow controllerand the first load heat exchangerwith a liquid pipeand a gas pipesequentially. A load refrigerant circuit B is formed by connecting the second compressor, the second load heat exchanger, the second flow controller, and the first load heat exchangerwith a load refrigerant pipe linesequentially.
