| 概要 |
The HFO-1132a refrigerant and its blends are considered for new generation refrigerants due to their zero ozone depletion potential and ultra-low global warming potential which can be used for variou...s existing applications of HFC-134a with minor modification. The saturated vapor pressures of pure HFO-1132a and its three binary blends (HFO-1132a) +(HFC-134a) under various mole ratios are computed in the temperature range of 240 K-300 K using COMPASS II force field via molecular dynamics simulations in this paper. The saturated vapor-liquid densities of the pure HFO-1132a and its binary blends are also estimated. Moreover, the phase diagram with critical points of pure HFO-1132a and the three blends are also predicted. The results indicate that as the proportion of HFC-134a is increased in the blend, the saturated pressure decreases and the liquid density increases. In case of vapor density, it does not follow any consistent trend.続きを見る
