Abstract
Computer simulation of refrigerating cycles for automotive air conditioners is effective in predicting performance of the cycle. A proper mathematical model of a compressor is necessary to predict the performance exactly. 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 the thermal effect of lubricating oil and heat transfer between refrigerant and the compressor body. Validity of the model is confirmed by comparison between experimental results and calculated ones. The transient behavior in the cycle simulation depends on the compressor modeling noticeably.
