To supply electric power stably.SOLUTION: A transportation refrigeration machine includes: a compressor power supply circuit which supplies electric power from a refrigeration machine side power source to a compressor; a refrigeration machine side relay which may electrically connect/disconnect the refrigeration machine side power source with/from an auxiliary machine; a vehicle side relay which may electrically connect/disconnect a vehicle side power source with/from the auxiliary machine; and a controller which controls power supply to the auxiliary machine. The controller may switch a power supply mode to the auxiliary machine among a first mode in which the refrigeration machine side relay is closed to electrically connect the refrigeration machine side power source with the auxiliary machine, a second mode in which the vehicle side relay is closed to electrically connect the vehicle side power source with the auxiliary machine, and a third mode in which the refrigeration machine side relay and the vehicle side relay are closed to electrically connect the refrigeration machine side power source with the vehicle side power source and the auxiliary machine. When the power supply mode is switched between the first mode and the second mode, the third mode is maintained for a preset time between the first mode and the second mode.SELECTED DRAWING: Figure 8

    【課題】電力供給を、安定して行う。【解決手段】輸送用冷凍機械は、冷凍機側電源から圧縮機に電力を供給する圧縮機電力供給回路と、冷凍機側電源と補器とを電気的に断続可能な冷凍機側リレーと、車両側電源と補器とを電気的に断続可能な車両側リレーと、補器に対する電力供給を制御する制御装置と、を備え、制御装置は、冷凍機側リレーを閉じて冷凍機側電源と補器とを電気的に接続する第一モードと、車両側リレーを閉じて車両側電源と補器とを電気的に接続する第二モードと、冷凍機側リレー、及び車両側リレーを閉じ、冷凍機側電源、及び車両側電源と補器とを電気的に接続する第三モードと、の間で補器に対する電力供給モードを切替可能であり、第一モードと第二モードとの間で、電力供給モードの切替を行う場合、第一モードと第二モードとの間で、第三モードを予め設定時間維持する。【選択図】図8
