Meanwhile, the refrigerant absorbs heat in the first heat exchanger 111 of each heat pump 110. That is, after absorbing heat of the first heat transfer medium circulated to the fan coil unit 123, the second heat exchanger 112 radiates heat. In this way, the refrigerant absorbs heat of the first heat transfer medium circulating along the first circulation line 120 extending to the fan coil unit 123, so that the fan coil unit 123 removes heat from the first chamber 121.
