To prevent a low-voltage battery 61 from running out.SOLUTION: A refrigerating machine 3 is mounted to a vehicle comprising a low-voltage battery 61 and an electronic control device 2a driven by output voltage from the low-voltage battery 61. The refrigerating machine 3 includes: an electric compressor 51 for controlling an interior temperature of a storage mounted to the vehicle by using output voltage from a high-voltage power source 60; and DC-DC converter 30. The refrigerating machine 3 includes a relay switch CMESF and an electromagnetic coil CM1 that control output voltage from the DC-DC converter 30 so as to apply the output voltage from the DC-DC converter 30 to the electronic control device 2a when the electric compressor 51 in operation while the vehicle is stopped. Therefore, when the refrigerating machine 3 is in operation while the vehicle is stopped, the output voltage from the DC-DC converter 30 can be applied to the electronic control device 2a.SELECTED DRAWING: Figure 1

    【課題】低電圧バッテリ61にバッテリ上りが生じることを防ぐ。【解決手段】冷凍機3は、低電圧バッテリ61と低電圧バッテリ61の出力電圧によって駆動される電子制御装置2aとを備えて構成される車両に架装される。冷凍機3は、高電圧電源60の出力電圧によって車両に架装される庫内の温度を調節する電動コンプレッサ51とDC−DC変換器30とを備える。冷凍機3は、車両の停車時にて電動コンプレッサ51の運転時にDC−DC変換器30の出力電圧を電子制御装置2aに与えるようにDC−DC変換器30の出力電圧を制御するリレースイッチCMESF、電磁コイルCM1を備える。このため、冷凍機3の停車時運転時にてDC−DC変換器30の出力電圧を電子制御装置2aに与えることができる。【選択図】図1
