Claims (1)
イルセパレータで分離し、この油を第１の油戻し
キヤピラリを介装した第１の油戻し路を経て上記
圧縮機内に戻すようにしたヒートポンプ装置にお
ける油戻し装置において、上記第１の油戻し路と
並列に第２の油戻し路を設け、この第２の油戻し
路に冷媒回路内の高低圧差或いは高圧又は低圧を
検知して開閉する弁と上記第１の油戻しキヤピラ
リよりも絞り度が小さい第２の油戻しキヤピラリ
を介装したことを特徴とするヒートポンプ装置に
おける油戻し装置。 A heat pump device in which oil contained in the refrigerant discharged from the compressor is separated by an oil separator, and the oil is returned to the compressor through a first oil return path interposed with a first oil return capillary. In the oil return device, a second oil return path is provided in parallel with the first oil return path, and the second oil return path is provided with a valve that opens and closes by detecting a high-low pressure difference, high pressure, or low pressure in the refrigerant circuit. and a second oil return capillary having a smaller degree of restriction than the first oil return capillary.
