摘　　要：临界参数是流体非常基础而重要的热物理性质。临界参数在涉及能源、化工、制药、环境等领域的科学研究和工程计算中有着广泛的应用。目前使用的部分制冷剂拥有较高的ODP和GWP,会逐渐被淘汰.因此,寻找新的替代物和替代方案是一项非常重要的任务。在替代物研究中,临界参数作为制冷剂的基础热物性,是首先要开展的研究.本文实验测量了R600a临界参数,用于检验实验装置的准确度和可靠性。结果表明,R600a的临界温度偏差为0.168 K,临界密度的相对误差为3.5%。在此基础上,测量了R161的临界温度、临界密度和临界压力,为替代制冷剂的研究提供了最基础的临界参数数据.The critical parameters, which are widely used in the energy, chemical, medicine and environment areas, are the most important thermal properties of fluids. Since ODP and GWP of the refrigerants used frequently in these days are in a high level, it is vital to exploit new alternative refrigerants. As the basic property of Refrigerants, the parameters should be primarily researched among all the studies about alternative refrigerants. In present work, the parameters of R600a have been measured to verify the experimental system. The absolute deviation of R600a＇s critical temperature and the relative deviation of R600a＇s critical density comparing with the literature are 0.168 K and 3.5% respectively. Then, the parameters of R161 have been measured.
