To provide a magnet heat cycle device which is high in heat transport efficiency, and its method.SOLUTION: There is provided a magnet heat cycle device being an MHP device 1 (magnetic heat amount effect type heat pump device). The MHP device 1 has an MCE element 4 (magnetic heat amount effect element) for exerting a magnet heat amount effect. The MHP device 1 has a magnet field modulation device 6 for modulating a magnet field applied to the MCE element 4. The MHP device 1 has a heat transport device 7 for creating a reciprocation flow of a heat medium 5 for exchanging heat with the MCE element 4. The heat transport device 7 compresses air bubbles in the heat medium 5 before a start of at least one flow of the reciprocation flow. The heat transport device 7 may compress the air bubbles immediately after a start of at least one flow of the reciprocation flow. The heat transport device 7 may compress the air bubbles within a period of at least one flow of the reciprocation flow.SELECTED DRAWING: Figure 1 【課題】熱輸送の効率が高い磁気熱サイクル装置および方法を提供する。【解決手段】磁気熱サイクル装置は、ＭＨＰ装置１（磁気熱量効果型ヒートポンプ装置）を提供する。ＭＨＰ装置１は、磁気熱量効果を発揮するＭＣＥ素子４（磁気熱量効果素子）を有する。ＭＨＰ装置１は、ＭＣＥ素子４に印加される磁場を変調する磁場変調装置６を有する。ＭＨＰ装置１は、ＭＣＥ素子４と熱交換する熱媒体５の往復流を生成する熱輸送装置７を有する。熱輸送装置７は、往復流の少なくとも一方の流れの開始前に、熱媒体５の中にある気泡を圧縮する。熱輸送装置７は、往復流の少なくとも一方の流れの開始直後に、気泡を圧縮してもよい。熱輸送装置７は、往復流の少なくとも一方の流れの期間中に、気泡を圧縮してもよい。【選択図】図１
