PVT properties of difluoromethane (HFC32).

Author(s) : FU Y. D., HAN L. Z., ZHU M. S.


A Burnett apparatus, which was designed and developed by the authors, is introduced in detail. 123 PVT data of R32 in the gaseous phase have been measured along 14 isotherms in the range of temperature from 243 to 373 K, pressure from 0.07 to 5.7 megapascals and density from 1.8 to 240 kg/m3. The uncertainty of temperature and pressure measurements have been estimated to be more or less 10 milliK and more or less 0.5 kilopascals respectively.
