基于灰色模糊综合评价法的空调系统优化

Grey fuzzy comprehensive evaluation of air conditioning systems

空调系统存在多种方案,涉及指标较多,合理构建评价体系至关重要。为了综合评价整个系统性能的优劣,提出了基于经济性、节能性、环保性和可靠性的12个指标。在此基础上,提出了基于灰色模糊综合评价的空调系统方法。该方法通过对模糊指标量化数值,建立定性定量指标的关联矩阵,并对总关联度比较大小,得到最优方案。最后以某地区办公建筑为例,利用这种方法对五种方案进行了优化抉择。结果表明,最优的空调系统方案为风冷热泵机组。

There are many schemes of the air conditioning system,which involve many indicators.It is very important to build a reasonable evaluation system.In order to evaluate the performance of the whole system,twelve indicators are proposed based on economics benefits,energy saving,environmental protection and reliability.Furthermore,gray fuzzy comprehensive evaluation is introduced and used.It is a method which quantifies the fuzzy indexes and establishes the correlation matrix formed with qualitative and quantitative index and compares the total correlation degree,obtain the optimal scheme.Finally,taking the office building in a certain area as an example,this method is used to optimize the five schemes.The result shows that the air-cooled heat pump unit is the optimal air conditioning system.
