To provide an on-vehicle refrigeration device enabling extension of an operable time of a refrigerator operated by using electric power of a battery.SOLUTION: An on-vehicle refrigeration device 1 mounted to a vehicle having an engine 10, a battery 20 and a freezing storage 3 includes: a refrigerator 30 having a steam compression type refrigeration cycle device with a compressor 31 and an indoor heat exchanger 38 and an indoor fan 39; and a refrigeration control section 5. The refrigerator 30 can exhibit a cooling function for cooling inside of the freezing storage 3 by causing the indoor heat exchanger 38 to function as a heat absorber. When the refrigerator 30 is operated so as to exhibit the cooling function by using power of the engine 10, the refrigeration control section 5 intermittently operates the compressor 31 while continuously operating the indoor fan 39. When the refrigerator 30 is operated so as to exhibit the cooling function by using electric power of the battery 20, the refrigeration control section 5 intermittently operates the compressor 31 while intermittently operating the indoor fan 39.SELECTED DRAWING: Figure 2

    【課題】バッテリの電力により動作する冷凍機の動作可能時間を延長する車載用冷凍装置を提供する。【解決手段】エンジン10、バッテリ20、冷凍庫3を有する車両に搭載される車載用冷凍装置1は、圧縮装置31と、室内熱交換器38と、を有する蒸気圧縮式の冷凍サイクル装置および室内ファン39を含む冷凍機30と、冷凍制御部5を備える。冷凍機30は、室内熱交換器38が吸熱器として機能することで冷凍庫3内を冷却させる冷却機能を発揮させることが可能である。冷凍制御部5は、エンジン10の動力を利用して冷却機能を発揮させるように冷凍機30を動作させる場合、室内ファン39を連続して動作させた状態で、圧縮装置31を断続して動作させる。また、冷凍制御部5は、バッテリ20の電力により冷却機能を発揮させるように冷凍機30を動作させる場合、室内ファン39を断続して動作させた状態で圧縮装置31を断続して動作させる。【選択図】図2
