WIPO Patent Application WO/2012/099128
Kind Code:
A1
Abstract:
In order to detect abnormalities in a valve mechanism, this indoor unit has an indoor heat exchanger disposed inside the indoor unit, and a radiation panel disposed on the outer surface of the indoor unit. A refrigerant circuit connecting the indoor unit and an outdoor unit has: a main flow path on which an outdoor electrically-operated valve (64), an outdoor heat exchanger, and a compressor (60) are disposed in that order; a first path on which the indoor heat exchanger is disposed; and a second flow path on which the radiation panel is disposed. The first flow path connects a branched part disposed downstream of the compressor (60) on the main flow path, and a merging part disposed upstream of the outdoor electrically-operated valve (64). The second flow path connects the branched part and the merging part to the first flow path in parallel. An indoor electrically-operated valve (23) is disposed on the second flow path between the radiation panel and the merging part. In addition, an abnormality detector (73) for detecting abnormalities that occur in the indoor electrically-operated valve (23) is provided.
