The heat source unit and the relay unit are connected to each other via heat source connection piping through which the refrigerant flows, and the relay unit and the plurality of indoor units are connected to each other via load connection piping through which the heat medium flows. The load connection piping includes a main pipe for connecting the relay unit to the indoor unit that is provided on the end opposite to the relay unit. The main pipe is provided with branch sections corresponding to the indoor units, among the plurality of indoor units, other than the indoor unit that is provided on the end opposite to the relay unit. The length of a portion, of the main pipe, from a section connected with the relay unit to a first branch section that is closest to the relay unit side, is shorter than the length of the heat source connection piping.
