[中文适用范围]： 本文件规定了几种常用制冷剂和制冷剂混合物的热物理特性。 本文件适用于制冷剂 R12、R22、R32、R123、R125、R134a、R143a、R152a、R290、R600a、R717（氨）、R744（二氧化碳）、R1233zd(E)、R1336mzz(Z)、R1234yf 和 R1234ze (E) 以及制冷剂混合物 R404A、R407C、R410A 和 R507A。 包括以下属性：单相状态和沿液体的密度、压力、内能、焓、熵、恒压热容、恒体积热容、声速和焦耳-汤姆逊系数- 蒸气饱和边界。 这些制冷剂的数字名称是 ISO 817 中定义的。 注 1：R12、R22、R123 是《蒙特利尔议定书》附件 A (R12) 或附件 C 第一组 (R22、R123) 下的受控物质。 注 2：R32、R125、R134a、R143a、R152a、R404A、R407C、R410A 和 R507A 是蒙特利尔议定书附件 F 或其混合物下的受控物质。 [外文原描述]： This document specifies the thermophysical properties of several commonly used refrigerants and refrigerant blends. This document is applicable to refrigerants R12, R22, R32, R123, R125, R134a, R143a, R152a, R290, R600a, R717 (ammonia), R744 (carbon dioxide), R1233zd(E), R1336mzz(Z), R1234yf and R1234ze(E) and to the refrigerant blends R404A, R407C, R410A, and R507A. The following properties are included: density, pressure, internal energy, enthalpy, entropy, heat capacity at constant pressure, heat capacity at constant volume, speed of sound, and the Joule-Thomson coefficient, in both single-phase states and along the liquid-vapour saturation boundary. The numerical designation of these refrigerants is that defined in ISO 817. NOTE 1 R12, R22, R123 are controlled substances under the Montreal Protocol, Annex A (R12) or Annex C Group I (R22, R123). NOTE 2 R32, R125, R134a, R143a, R152a, R404A, R407C, R410A, and R507A are controlled substances under the Montreal Protocol, Annex F or blend thereof.
