热泵的应用-------外文翻译.doc

1.Heat pumps in industry
1). Systems
Relatively few heat pumps are currently installed in industry. However, as environmental regulations become stricter, industrial heat pumps can become an important technology to reduce emissions, improve efficiency, and limit the use of ground water for cooling
To ensure the sound application of heat pumps in industry, processes should be optimised and integrated. Through process integration improved energy efficiency is achieved by thermodynamically optimising total industrial processes. An important instrument for process integration is pinch analysis, a technology to characterise process heat streams and identify possibilities for heat recovery. Such possibilities may include improved heat exchanger networks, cogeneration and heat pumps. Pinch analysis is especially powerful for large, complex processes with multiple operations, and is an excellent instrument to identify sound heat pump opportunities.
Industrial applications show a great variation in the type of drive energy, heat pump size, operating conditions, heat sources and the type of application. The heat pump units are generally designed for a specific application, and are therefore unique.



1热泵在工业上的应用

1）系统
目前，在工业领域当中只有较少的热泵得到运用。但，随着环境要求的逐步的提高，工业热泵变成一种可以用来减少散发，提高效率以及在制冷过程中限制地下水过多使用的重要的技术。
在总的工业流程中，能效的提高是通过综合处理由热力状态来完成的。因此，为了确保热泵在工业中的充分利用，这就需要合理、全面的处理。挤压分析是综合处理中的一种重要的方法，这种技术能表现出处理热的趋势和鉴定热回收的可行性，可行性包括改善热交换网络和热泵。挤压式分析对大型复杂的综合控制过程是特别有效的，并且是一种一个挑选适合的热泵的机会。
在工业应用上，热泵已经在运行能源的形式、型号、控制条件、热源和应用方式上等许多方面都发生了很大的变化。热泵各个组成部分通常是为了一个特殊的应用而设计的，因此热泵也是独特的。
