【摘要】 本文从Clapryron相变热方程出发,将汽化热与对比温度进行了关联,得到一个新的估算液体汽化热的方程式,该式型式简单,参数少,只需要知道物质的临界温度、偏心因子以及摩尔气体常数就能计算,便于应用。利用新方程对31种制冷剂的汽化热进行了计算,平均绝对偏差为1.54%,满足工程需要。更多还原

【Abstract】 In the present work,a new equation for estimating vaporization heat of refrigerants was developed by applying the Clausius-Clapeyron equation.The equation is simple and only need three parameters to calculate.The vaporization heat of 31 pure refrigerants was calculated to verify the new equation,with the average absolute deviation 1.54%,compared with the literature values.更多还原
