| Abstract(J) | BEVの熱マネジメントシステムは運転モードが多様化し，中核を担う冷凍サイクルへの要求が⾼度化している．特にコンプレッサーは冷媒に溶解したオイルで潤滑されるため，潤滑性と効率の両⽴が鍵となる．本報では，サイクル内オイル挙動を物理現象から予測する独⾃モデルを構築し，実機計測値を⾼精度に再現したので報告する． Translation |
| Abstract(E) | Thermal management systems for BEVs have seen increasing diversification of operating modes, raising the demands placed on the refrigeration cycle that lies at their core. The compressor, in particular, is lubricated by oil dissolved in the refrigerant, making it essential to achieve both adequate lubrication and high efficiency. In this report, we present an original model that predicts oil behavior within the cycle based on the underlying physical phenomena, and demonstrate that it reproduces measured values from actual equipment with high accuracy. |
