PROBLEM TO BE SOLVED: To provide a vehicular refrigeration device capable of reducing power consumption of an air blower, while cooling the inside of a box at maximum refrigeration capability according to an in-box temperature.SOLUTION: In a vehicular refrigeration device, an air amount of a second air blower is suppressed with an air amount to be maximum refrigeration capability at air temperature detected by an in-box temperature sensor. Since an air amount to be maximum refrigeration capability differs in an in-box temperature, when an air amount is fixed, power may be wastefully consumed by the second air blower. Then, an air amount is controlled according to an in-box temperature, and an air amount is controlled to an optimal air amount every time an in-box temperature is detected.SELECTED DRAWING: Figure 6 【課題】庫内温度に応じた最大冷凍能力で庫内を冷却しつつ、送風機の消費電力を低減することができる車両用冷凍装置を提供する。【解決手段】車両用冷凍装置では、庫内温度センサに検出された空気温度で最大冷凍能力となる風量を用いて第２送風機の風量が制御される。庫内温度で最大冷凍能力となる風量が異なるので、風量が固定されている場合には、第２送風機によって無駄に電力が消費することがある。そこで庫内温度に応じて風量が制御し、風量が庫内温度が検出される毎に最適な風量に制御する。【選択図】図６
