AIR CONDITIONER

Document Type and Number:

WIPO Patent Application WO/2010/050001

Kind Code:

A1

Abstract:

A heat source-side heat exchanger (12), intermediate heat exchangers (15a, 15b), and a utilization-side heat exchanger (26a-26d) are constructed separately from each other so that they can be placed at positions separated from each other. Flow path switching valves (22a-22d, 23a-23d) are provided on the entrance side and the exit side, respectively, of a heat medium flow path of the utilization-side heat exchanger (26a-26d). The flow path switching valves (22a-22d, 23a-23d) switch flow paths to connect the utilization-side heat exchanger (26a-26d) to each intermediate heat exchanger (15a, 15b). A pump (21a-21d) for circulating a heat medium in a heat medium circulation circuit is provided either in a flow path between the utilization-side heat exchanger (26a-26d) and the flow path switching valve (22a-22d) placed on the entrance side of the utilization-side heat exchanger or in a flow path between the utilization-side heat exchanger (26a-26d) and the flow path switching valve (23a-23d) placed on the exit side of the utilization-side heat exchanger.
