Summary

The steady-state characteristics of a refrigeration cycle for automotive air conditioners using R12 gas was studied numerically. The numerical method for the simulation of a refrigeration cycle executed on a personal computer is presented. The model for a refrigeration cycle consists of a compressor, condenser, expansion valve and evaporator. Non-linear equations for pressure, temperature and refrigerant mass were calculated by the Newton-Raphson method. In particular, experimental data were used for calculation of compressor condition, and influence of refrigerator oil is considered. By comparing with the experiment, it is clear that this simulation is useful for predicting the performance of a refrigeration cycle.
