There has been a continuous effort to evaluate the performance of alternative refrigerants, which can substitute conventional working fluids like R410A, in current HVAC&R systems to have reduced environmental impact. This seminar highlights the performance of low GWP and A2L refrigerants and blends under flow boiling or evaporation inside internally enhanced tubes, small size channels, and plate heat exchangers. The seminar helps to identify the potential of Artificial Neural Network to predict the boiling heat transfer coefficients for the new refrigerants. This session will benefit engineers to design improved heat exchangers for their new or existing systems.
