Abstract
This paper deals with the experimental study for the heating performance that could be used for R-134a automobile heat pump systems. Heat pump system is widely studying for zero emission vehicles heating system due to small power consumption and effectively heating in the cabin. This paper presents experimental results of the influence of the heating capacity and coefficient of performance. The test was performed with different size of inside heat exchangers and outside heat exchangers, also refrigerant flow rate was considered in two way of flow devices. And heat source, means air heat source and water heat source with heat pump system was examined. The experimental results with heat pump system is to analyze the impact on performance. The best combination of performance is A-inside heat exchanger, B-outside heat exchanger, and B-flow device respectively. And water heat source is roughly 40% better performance than air heat source heat pump system.
