Abstract

In this chapter, an accumulator-capillary tube-suction line heat exchanger was developed and investigated experimentally with comparison to conventional systems with and without a liquid line-suction line heat exchanger. The experiments were carried out on AACTS, at three compressor speeds of 700, 1,500 and 2,000 rpm. The working fluid used in the experiment was R-134a, and lubricating oil was Polyalkylene Glycol (PAG) oil. Variables investigated include mass flow rate, vapour quality, discharge pressure, compression ratio, cooling capacity, power input, coefficient of performance, discharge temperature and isentropic and volumetric efficiencies of compressor. The results showed that both kinds of internal heat exchanger have positive influences on the performance of automotive AC systems.
