This paper presents oil retention and pressure drop data for R410A with polyvinylether(PVE) oil at the compressor suction line. Instead of real heat pump system, an experimental device which is possible to simulate compressor suction line was used. Test section consists of 15.88 mm outer diameter pipe with 3 m length. Syringe pump and oil level sensor were used for measuring oil retention and differential pressure transmitters were used for measuring pressure drop. To get the oil retention and pressure drop per unit length, entrance length has to be considered. In this research, it was possible to confirm fully developed flow by comparing pressure drop data. The entrance length was less than 1 m under all test conditions. The mass flux and the oil circulation ratio (OCR) both varied in the range of 31-66 kg/㎡s and 2-4% respectively. Oil retention was decreasing trend as OCR decreased or mass flux increase. Pressures drop was increasing trend as OCR increased or mass flux increased.
