为了节约用于加热送风的燃料消耗,研究了使用中间热载体的热回收装置。热交换器的计算图式如图1所示。某些文献中指出,对空调系统的装置来说,可以近似地看成为服从刘易斯关系式。对“干换热”部分而言,水空气之间的热转移是在同一种势差——温度差的作用下实现的。因此,这种类型的热交换器的传热方程式非常简单并具有如下形式: 对具有水气凝结的部分,在某断面(?)处,热交换器表面和空气之间的热交换方程式可
In order to save fuel consumption for heating the air supply, a heat recovery device using an intermediate heat carrier has been studied. The heat exchanger calculation pattern is shown in Figure 1. Some literature points out that for air-conditioning system installations, it can be seen as an approximation of Lewis’s relations. For the “dry heat transfer” part, the heat transfer between water and air is achieved under the same potential difference, temperature difference. Therefore, the heat transfer equation of this type of heat exchanger is very simple and has the following form: For the part with water vapor condensation, the heat exchange equation between the heat exchanger surface and the air at a certain section (?) can be
