Microfiltration for Capillary Tube Use

Selection of Capillary Tube for Refrigeration System

Proper selection of capillary tube it is essential to study the effect of capillary tube geometry on the performance of refrigeration systems. The literature review is focused on the influence of geometrical parameters like tube length, diameter, coil pitch, number of twist and twisted angle on pressure drop and coefficient of performance (COP) of the system. These parameters can be optimized u...

Constitutive Equations for Capillary Tube Modeling

This paper presents the results of an experimental study on capillary tubes commonly used as expansion device in household refrigerators and freezers. The experiments were performed with HFC-134a at different condensing pressures and level of subcooling. The pressure and temperature profiles along the capillary tubes were measured in each test run. The data set was then used to evaluate the sui...
