カーエアコンサイクルにおけるべーン形圧縮機の計算モデル

抄録

Computer simulation of refrigerating cycles for automotive air conditioners is effective in predicting performance of the cycle. To predict the performance exactly a proper mathematical model of a compressor is needed. In this study, the mathematical model of a vane compressor for the automotive air conditioning cycle is developed. The model consists of two control volumes, a cylinder and a rear case, and a compressor body. It takes account of influences of lubricating oil and heat transfer between refrigerant and the compressor body. Validity of the model is confirmed by comparison between calculated results and experimental ones. Propriety of the compressor modeling in the cycle simulation influences transient behavior of the cycle greatly.
