This project is aimed to study new enhanced surfaces during two phase flow of refrigerants. The proposed surfaces are: metal foams, nanoporous coated surfaces, and mini microfin tubes. The project will be carried out at the Laboratory of Heat Transfer in Microgeometries, of the Dipartimento di Ingegneria Industriale. In this laboratory, there is a two phase heat transfer set up designed for the study of these new enhanced surfaces. The working fluids will be low GWP refrigerants, such as R1234ze(E), R1234yf and also the common R134a, used as a benchmark to compare the new fluids. These fluids will be tested during vaporization through metal foams, over nanoporous coated surfaces and through mini microfin tubes. Mini microfin tubes will also be tested during condensation, in order to study the possible viable implementation in a real air conditioning equipment
