R22/R113的PVTx性质试验研究

THE MEASUREMENTS OF PVTx PROPERTIES FOR R22/R113 SYSTEM

以使用R22/R113工质对的新型热泵为背景,用定容法测定了60mol％ R22/40mol％R113的PVT数据。本文发表温度范围为287K～454K,压力0.55MPa～5.74MPa,11条定容线上共112实测数据,可供工程计算应用。

Based on the background of R22/R113 mixture using in vapor compression heat pump cycle with desorber and absorber heat exchange, 250 PVTx experimental data of 60 mol %R22 + 40 mol% R113 along 11 isochores have been measured by the constant volume method in the temperature range of 287K-454K and the pressure range of 0.55MPa-5.74MPa. 112 data are published here. The accuracy of measurement is 1.1 kPa-3.7 kPa (0.207%-0.065%) for pressure, 0.04%-0.25% (v = 1.4248cm3/g-9.9649 cm3/g) for specific volume, and ±36mK for temperature.
