Abstract (en)
[origin: EP2667109A1] 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 principal channel on which an outdoor motor-operated valve (64), an outdoor heat exchanger, and a compressor (60) are disposed in that order; a first channel on which the indoor heat exchanger is disposed; and a second channel on which the radiation panel is disposed. The first channel, during heating operation, connects a branching section disposed downstream side of the compressor (60) on the principal channel, and a merging section disposed upstream side of the outdoor motor-operated valve (64). The second channel connects the branching section and the merging section to the first channel in parallel. An indoor motor-operated valve (23) is disposed on the second channel between the radiation panel and the merging section. In addition, an abnormality detector (73) for detecting abnormalities that occur in the indoor motor-operated valve (23) is provided.
