Abstract
The experimental research of environmentally friendly refrigerant HFE-7100
condensation in pipe minichannels was conducted. During the investigations
of HFE-7100 condensation in a minichannel with internal diameter 2 mm
together with visualization of flow patterns was made. Visualization
results were compared with existing flow structure maps. The
identification of the range of flow patterns occurrence during the
condensation process of low-pressure refrigerant HFE-7100 was made. The
tests were performed throughout the whole range of condensation process.
