In Vapour compression refrigeration system used are a different diameter and shape of capillary tube and refrigerant. The design of capillary is helical capillary tubes and refrigerant of R134a and R134a mix in Hydrocarbon (HC). The capillary tube used mostly in the refrigerant flow control devices. Hence performance of the capillary tube should be good for smooth refrigerant flow. In domestic refrigerators widely used refrigerant R134a. R134a refrigerant is a Hydro fluorocarbon (HFC) with high global warming potential of 1200 and hence it A numerical study has been carried out for with CO2 refrigerant. The numerical models are developed based on the fundamental conservation principles of mass, momentum, and energy. Within this, outer loop, the ordinary differential equations are solved from the inlet to the exit of the capillary tube. Helical coiled capillary tube of 1.5mm, 1.7mm, 1.9mm diameter carried out from of refrigerant R134a and mix in Hydrocarbon (HC). The findings of the experimental study revealed that the mass flow rate is maximum for the 1.9 mm diameter of the capillary tube and is found to be 4.2g/s and 1.7mm diameter of the capillary tube and is found to be 4.5g/s at same operating conditions for R134a&HC. Moreover, for the mixture of R134a&HC maximum pressure ratio at 1.5mm dia. of capillary is 11.81 and minimum pressure ratio at 1.9mm dia. of capillary is 8.40 C.O.P assessed for R134a at 1.7mm dia. capillary gave better result over the 1.9mm dia. and 1.7mm dia. capillary. Maximum COP is found to be 4.50 at 1.9 mm diameter. Carnot C.O.P for R134a refrigerant at 1.7mm diameter capillary is found to be 4.28 and for mixture of R134a&HC at 1.9mm diameter capillary is 4.5 which is better than another diameter. In this study it has been concluded that the performance mixture of refrigerant R134a&HC is found to be better than R134a. The present work is focused on the influence of tube diameter, tube length, coil pitch, and inlet condition on mass flow rate of refrigerant through helical coil capillary tube and also on investigation about the Coefficient of Performance (COP) of the system due to coiling effect of capillary tube. The use of helical capillary tube reduces the space for the refrigeration system which is the need for more compact refrigeration system in the current trend.
