1966年初，因制冷剂热物理性质公布值不准确而引起的问题引起了ASHRAE研究和技术委员会的注意。反过来，他们在技术委员会1.3F（传热和流体流动）下成立了一个小组委员会，进一步研究不同制冷剂可用数据的不同数量和质量。随着计算机的使用越来越多，允许在“正常”和“非设计”条件下对制冷剂热交换器进行更详细和准确的计算，有必要了解制冷剂在各种条件下的热物理性质（特别是比热、粘度和导热系数）。 委员会决定，最好的方法是首先确定文献中的可用值，然后确定报告值中最正确的值，并获得文献中没有信息的制冷剂和条件的估计值。最终的结果是，SOUGHT以一种可供制冷行业使用的形式发布了一整套一致的值，以帮助工程师更统一地评估测试数据并比较热交换器。引文:巴哈马拿骚ASHRAE Transactions第78卷第2部分

Early in 1966 problems arising from inaccuracies in published values of the thermophysical properties of refrigerants were brought to the attention of ASHRAE's Research and Technical Committee. In turn they set up a subcommittee under Technical Committee 1.3F (Heat Transfer and Fluid Flow) to study further the varying amount and quality of data available for different refrigerants. With the increased use of computers permitting more detailed and accurate calculation of refrigerant heat exchangers at both "normal" and "off-design" conditions, it is necessary to know the thermophysical properties (in particular, specific heat, viscosity, and thermal conductivity) of the refrigerant being considered over a wide range of conditions.The committee decided the best approach would be to first determine what values are available in the literature, then decide what values of those reported are most correct and obtain estimates of values for the refrigerants and conditions for which there are no information in the literature.The final result souught was a full set of consistent values published in a form available to the refrigeration industry to help engineers more uniformly evaluate test data and compare heat exchangers.
