カーエアコンに用いる高性能エバポレータの開発

圧力損失低減による性能向上と温度分布の均一化を冷媒の流し方(Xターン流れ)で両立

In recent, environmental regulations have been tightened, and the development and introduction of Battery Electric Vehicles are accelerating. Since not only the passenger but also the electronic equipment cooling is required for car air conditioners, it is necessary to increase the cooling performance of evaporators. In addition, since the power saving is required for car air conditioners to improve the cruising range of Battery Electric Vehicles, it is necessary to save the cooling performance by zone air conditioner. We have developed a new structure that can achieve both cooling performance at high flow rates and uniform air temperature distribution at low flow rates by using the refrigerant flow that can reduce the pressure drop inside the evaporator.
