一.什么是水和水蒸气的焓?
水或水蒸气的焓h，是指在某一压力和温度下的1千克水或1千克水蒸气内部所含有的能量，即水或水蒸气的内能u与压力势能pv之和(h=u+pv)。水或水蒸气的焓，可以认为等于把1千克绝对压力为0.1兆帕温度为0℃的水，加热到该水或水蒸气的压力和温度下所吸收的热量。焓的单位为“焦/千克”。
(1)非饱和水焓：将1千克绝对压力为0.1兆帕温度为0℃的水，加热到该非饱和水的压力和温度下所吸收的热量。
(2)饱和水焓：将1千克绝对压力为0.1兆帕温度为0℃的水，加热到该饱和水的压力对应的饱和温度时所吸收的热量。饱和温度随压力增大而升高，因此饱和水焓也随压力增大而增大。例如：绝对压力为3.92兆帕时，饱和水焓为1081.9 x 103焦/千克;在绝对压力为9.81兆帕时，饱和水焓则为1399.3 x 103焦/千克。
