Experimental Study of HFE 7000 Refrigerant Condensation in Horizontal Pipe Minichannels

This article presents the results obtained from our own experimental investigations on heat exchange and pressure drop during the condensation flow of the HFE 7000 refrigerant in pipe minichannels with an internal diameter of d<sub>i</sub> = 1.2–2.5 mm. The influence of vapor quality x a...
