在过去十年中，人们对二氯二氟甲烷（R-12）的替代制冷剂产生了相当大的兴趣，理论表明，这种制冷剂可能会导致高层大气中臭氧的消耗。一种“平流层安全”的新制冷剂是1,1,1,2-四氟乙烷（R-134a），它在热力学上与R-12相似，被认为是空调和制冷应用中R-12的潜在直接替代品。本文给出了R-134a上新的P-V-T、饱和蒸汽压、液体密度、理想气体热容和临界常数数据。比较了R-134a和R-12的热力学性质。此外，热力学数据与状态方程相关联，从状态方程可以计算焓和熵。使用适当的算法，开发了一个Fortran计算机包，用于生成各种温度和压力下的热力学表。 单位:双引文:研讨会，ASHRAE交易，1988年，第94卷，pt。2、渥太华

Considerable interest has developed over the last decade in substitute refrigerants for dichlorodifluoromethane (R-12), which theories have suggested may contribute to the depletion of ozone in the upper atmosphere. One "stratospherically safe" new refrigerant is 1,1,1,2-tetrafluoroethane (R-134a), which is thermodynamically similar to R-12 and considered to be a potential direct replacement for R-12 in air-conditioning and refrigeration applications.In this paper, new P-V-T, saturated vapor pressure, liquid density, ideal gas heat capacity, and critical constant data are presented on R-134a. The thermodynamic properties of R-134a are compared to those of R-12. In addition, the thermodynamic data are correlated to an equation of state from which enthalpies and entropies can be calculated. Using appropriate algorithms, a Fortran computer package has been developed to generate thermodynamic tables over a wide range of temperatures and pressures.Units: Dual
