任何工序或设备的能源利用效率和节能量的分析,都需要确定一个明确的研究对象,需要采用某种方法把这个研究对象从复杂纷乱的环境中“隔离”出来,使它与周围的环境相区别,而且与周围的环境发生确定的联系或关系。这种确定系统和明确边界的方法就是热力学方法。合理选择热力学系统,对项 An analysis of the energy efficiency and energy savings of any process or plant requires identifying a clear research object that requires some means of “isolating” the subject from the complex and chaotic environment and making it relevant to the surrounding The environment is different, and there is a definite connection or relationship with the surrounding environment. This method of determining the system and defining the boundaries is a thermodynamic method. Reasonable choice of thermodynamic system, on the item
