过程网络中的热电集成的一般问题是复杂的，迄今尚未完全理解。本课程涵盖现场热电联产、电厂发电、热泵和制冷系统。本文是两部分系列的第一部分，并解释了基于基本新见解的过程网络中“适当”热机和热泵放置的概念。“适当”的放置利用了与过程其余部分的集成机会，并产生了远高于通过独立的热力发动机所能实现的边际效率。相反，“不适当”的放置永远不会比独立系统更有优势。第二部分介绍了初步设计的程序，包括热机，热泵设备的选择和性能评估。
The general problem of heat and power integration in process networks is complex and to date not fully understood. The subject covers site combined heat and power, on-plant power generation, heat pumps, and refrigeration systems. This paper is the first of a two-part series and explains the concept of ''appropriate'' heat engine and heat pump placement in process networks based on a fundamental new insight. ''Appropriate'' placement takes advantage of integration opportunities with the remainder of the process and yields marginal efficiencies far greater than could be achieved through stand-alone heat engines. Conversely, ''inappropriate'' placement can never offer an advantage over stand-alone systems. Part II describes procedures for preliminary design, involving heat engine, and heat pump equipment selection and performance assessment.
