A capillary tube is widely used as throttling device in small sized refrigeration and air-conditioning applications having capacity less than 3 TR. This research paper provides a set of capillary tube performance data in a vapor compression refrigeration system using R-134a as working fluid. Several capillary tubes with different length and inner diameter were selected as testsections. Mass flow rate and Pressure drop through capillary tube was measured for several inlet temperatures of each capillary tube. The sub cooling and superheating temperatures are maintained constant throughout the experimentation. Experimental conditions for the condensing temperatures were selected from 38 to 54º C in the interval of 2º C.
