冷热电联供系统的综合效能评价指标

An evaluation method of combined cooling,heat and power based on economic and social benefits

冷热电联供系统(CCHP)由于能够实现对能量梯级利用,具有节能、环保等特点,因而受到广泛关注。由于同时存在多种形式的能量输出,冷热电联供系统是一种全新的、复杂的能量供应系统。为了确定不同系统形式的优劣,指导系统的设计、选择,需要对不同系统形式进行综合评价。目前对冷热电联供系统的评价方式较多,但不同评价方式存在一些矛盾之处。对典型冷热电联供系统的运营模式、评价体系进行阐述,进而提出可行的冷热电联供系统评价指标。

The combined cooling,heating and power(CCHP)has attracted widespread attention due to its energy cascade utilization,energy saving,and environmental protection.Because there are many forms of energy output,the cogeneration system is a new and complex energy supply system.In order to determine the pros and cons of different systems,to guide and optimize the design and selection of the system,the system needs to be evaluated.At present,there are many evaluation indexes of the combined heat and power system,but there are some contradictions in different evaluation criteria.This paper explains the operation mode and evaluation system of a typical combined cooling,heating and power system.
