This paper represents an experimental investigation about effect of simple and twisted spirally coiled adiabatic capillary tube on the refrigerant flow rate. Several capillary tubes with different inner diameters, lengths and pitches are taken as test sections. An eco-friendly refrigerant; LPG is taken as alternative of R-134a having lesser GWP and ODP. Coiling spirally and cross sectional changes because of twist on capillary tube along the length has its influence on mass flow rate and cooling effect that can be invariably marked. Mass flow rate for different capillary tubes are measured for different degrees of sub cooling with constant inlet pressure of capillary. For comparison, the experiments have also been conducted for straight capillary tube and it has been observed that the mass flow rates in spiral coiled capillary tube are less than those in a straight one where as in twisted spiral coiled capillary tube, refrigerant flow rate is further reduced.
