Résumé

Flexible short-tube orifices were designed to decrease their diameter as the pressure differential across them increases under high outdoor temperatures. A series of tests for an R22/lubricant mixture (mass fraction of oil 1.2%) were performed with two flexible short-tube orifices to develop flow data over a range of typical air conditioner operating conditions. The tests included both single- and two-phase flow conditions at the inlet of the flexible short tube. Upstream pressures were varied from 1179 to 2144 kPa, which corresponded to saturated condensing temperatures of 29.4 to 54.4 °C. Experimental results were presented as a function of pressure, subcooling/quality, evaporating pressure, and modulus of elasticity. An empirical flow model was developed using the experimental data.
