Abstract:
A refrigeration cycle is configured by connecting a compressor that compresses the refrigerant, a four-way valve that switches the circulation path of the refrigerant, a heat source side heat exchanger that exchanges heat, expansion valves that adjust the pressure of the refrigerant, and two or more intermediate heat exchangers that exchange heat between the refrigerant and the heat medium to heat and cool the heat medium, by piping. A heat medium circulation circuit is configured by connecting two or more intermediate heat exchangers, pumps that pressurize the heat medium, two or more use side heat exchangers that exchange heat between the heat medium and the air in the indoor space, and flow path switching valves that switch paths of the heated heat medium or the cooled heat medium to the use side heat exchangers, by piping.
