| 摘 要： | 喷射式热泵的引射系数在运行过程中会因工作蒸汽的压力、引射蒸汽的压力和混合蒸汽出口压力的变化而发生较大的改变,这对于保证热泵的正常工作是不利的;本文运用变量全微分的方法推出了这些影响因素对于引射系数影响的数学模型,为运行时预测引射系数的变化提供了一种简单可靠的计算方法。

| Abstract: | The ejecting ratio of heat pump will vary with the pressure of working steam, extracting steam and the mixture in the process of operation which will corrupt the normal operation of heat pump. The mathematical model of calculating the ejecting ratio has been deduced with the method of variable total differential in this paper, which provide a simple and reliable way to predict the ejecting ratio. |
