An increase in global warming potential and other environmental concerns are demanding new environmentally friendly refrigerants. For investigation of system performance of newly developed refrigerants, the convective heat transfer coefficient in two-phase flow for both boiling and condensation is required. In the literature, numerous works have been done on in-tube condensation of various refrigerants and it is noticed that most of the works are based on conventional test rigs involving dual refrigeration arrangement without a compressor for the in-tube condensation analysis. This work is mainly focused on developing an innovative low cost highly efficient in-tube condensation test rig for flow condensation analysis of refrigerants. The in-tube condensation test rig is successfully fabricated, and the experiments are conducted for R134a refrigerant. The experiments are conducted for mass flux varying from 150 -320 kg/m2s with different vapor qualities ranging from 0.3 to 0.9. Further, the results obtained are validated against MM Shah’s unified correlation and the comparative results are also presented it is observed that the experimental results are in good agreement with that of Shah’s correlation results.
