| Abstract: | PVTx behaviors of HC1270/HFC227ea, HC290/HFC227ea, and HC170/HFC227ea were experimentally investigated with a new version of PVTx apparatus. 60 measurements were taken with a precision of 5 mK, 0.4 kPa, 0.2% and 0.3% for temperature, pressure, specific volume, and composition respectively. |
