| Abstract: | A new apparatus has been developed for investigation of vapor-liquid equilibria for low-temperature refrigerants. The experiments can be performed over a wide temperature range from 140 to 300 K and pressures up to 7 MPa, and has high precision. In order to check the reliability and accuracy of the entire system, several test measurements have been made on the saturation pressure of C3H8 and VLE data of the C2H6 C3H8 system. The results show good agreements with the reference data. |
