摘要

建立了流动型量热法汽化热测量装置 .该装置测量压力可达 6MPa

温度范围 2 6 0～ 480K .以所建的装置测量了纯水的汽化热

测量结果与文献值比较其偏差在± 0 .85 %以内

证明了实验装置的可靠性 .利用该装置测量了制冷剂的替代工质HFC134a和HFC12 5的汽化热

为替代工质的筛选和工程设计提供了可靠的基础数据

Abstract

A flow apparatus for measuring heat of vaporization of liquids under pressure up to 6 MPa

and temperature from 260 K to 480 K is developed.Heats of vaporization of water are measured

and the differences of our experimental results with literature values are within 0.85%.The heats of vaporization HFC134a and HFC125 used as the alternatives of refrigerant Freon are determined

and 14 values of heat of vaporization are reported in this paper.
