Abstract

To learn about the factors that can improve the overall performance of a simple
vapour compression refrigeration system, it's important to examine the device responsible
for the system's expansion. An investigation into how capillary tube geometry impacts
cooling efficiency is crucial. The literature review centres on the relationship between
geometrical parameters and system performance metrics such pressure drop, COP, and
mass flow rate. These factors include capillary tube length, bore diameter, coil pitch,
number of twists, and twisted angle. Improve the efficiency of the cooling system by
tweaking the aforementioned settings. In this study, we examine how changing the tube
diameter, tube length, coil pitch, and inlet condition affects the mass flow rate of the
refrigerant through the helical coil capillary tube, as well as how the coiling effect of the
capillary tube affects the system's COP. In order to meet the modern trend toward smaller
refrigeration systems, helical capillary tubes are increasingly being used.
