ISO 17584:2005规定了几种常用制冷剂和制冷剂混合物的热物理性质。
ISO 17584:2005适用于制冷剂R12、R22、R32、R123、R125、R134a、R143a、R152a、R717(氨)和R744(二氧化碳)以及混合制冷剂R404A、R407C、R410A和R507。包括以下性质:密度、压力、内能、焓、熵、恒压热容、定容热容、声速和焦耳-汤姆逊系数,在单相状态和沿液-汽饱和边界。这些制冷剂的数字名称如ISO 817所定义。
ISO 17584:2005 specifies thermophysical properties of several commonly used refrigerants and refrigerant blends.
ISO 17584:2005 is applicable to the refrigerants R12, R22, R32, R123, R125, R134a, R143a, R152a, R717 (ammonia), and R744 (carbon dioxide) and to the refrigerant blends R404A, R407C, R410A, and R507. 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.
