In their work Yilmaz and Unal (1996) assumed an isenthalpic process and developed a relation between specific volume and pressure in the vapor mixture region, based on Clausius-Clapeyron equation. Due to the relatively close mass flow of R448 and R22, little to no adjustment of the TXVs is expected. The list of capillary tube inner diameters typically includes available sizes from different countries. It is evident that for all Refrigerants used, the combination of length & inner diameter of capillary tube are same in analytical method as well as in cooling capacity test.
