Influence of refrigerant charge variation on the performance of an automotive refrigeration system.

Author(s) : PRÖLSS K., SCHMITZ G., LIMPERICH D., et al.

Summary

Refrigerant charge losses in an automotive air-conditioning system accumulated over a long period of time lead to inefficient operation. To identify characteristic steady-state behaviour with respect to variable system charges, an R-134a refrigeration cycle is investigated experimentally and numerically. A closer look is taken at the receiver component, which is supposed to separate vapour from liquid and to balance changing refrigerant demands under different operating conditions. A clear receiver integrated in the experimental setup allows for a visual insight into its phase separation behaviour and provides information used in the numerical model. Simulation and experimental results are compared in terms of measurable system variables. The receiver impact on those results as well as on the system's efficiency is discussed.
