Abstract
A refrigeration cycle is configured by connecting a compressor, a four-way valve, a heat source side heat exchanger, expansion valves, and intermediate heat exchangers by piping. A heat medium circulation circuit is configured by connecting intermediate heat exchangers, pumps, and use side heat exchangers by piping. The outdoor unit accommodates the compressor, the four-way valve, and the heat source side heat exchanger, and the relay unit that is installed in a non-subject space which is different from an indoor space and is on an installation floor separated by two or more floors and accommodates the expansion valves, the pump, and intermediate heat exchangers are connected by two pipelines. The relay unit and an indoor unit that accommodates use side heat exchangers and is installed at a position where an indoor space can be air-conditioned are connected by two pipelines.
