Summary
The paper presents experimental data for capillary tubes of the type commonly used as expansion devices in domestic appliances, employing R12 and R134a as working fluids. Capillary tubes of 0.7, 0.8 and 1 millimeter internal diameter with lengths of 3 and 2 meters were tested. Condensing pressures of 1,800, 1,400, 1,100 and 900 kilopascals, and subcooling ranging from 14 to 2 K were chosen as the operating conditions. Choked conditions prevailed in all runs. The test rig and the experimental procedures are described in detail. The uncertainties of all the measurements are also given.
