This paper gives summary of research on the characteristics of different refrigerant considering Non Adiabatic flow inside the capillary tube expansion device for various applications. This paper gives the summary of range of geometric and operating parameters like capillary tube length, diameter, suction line diameter, suction line length, heat exchanger length, surface roughness of capillary tube, suction line inlet temperature, coil pitch, inlet sub cooling, condenser pressure, and evaporator pressure etc. The outcome of different research is summarized in tabular form. This paper also gives type of approach, correlation proposed and some special information about investigation. It is found that the literature in Non Adiabatic capillary tube is scare so more investigation is required.
