供热空调系统方案的多目标综合评价研究

Study of the Multiple Objective Comprehensive Evaluation for Heating and Air-Conditioning Systems

分析了6种供热空调系统方案在3种不同运行情况下的一次能源利用率PER,得出燃气热泵的PER最高.但在供热空调系统可行方案的优选中,方案的选择受多种因素影响,其中许多不能量化的指标常被忽略,决策时产生偏差.利用多目标决策的方法,对多目标系统进行优选,从环境因素、成本因素和性能因素等方面对6种采暖空调系统方案进行综合评价研究,给出了方案选择的指导性意见,提高了方案决策的合理性和科学性.

This paper analyzes primary energy ratio(PER)of six different heating and airconditioning systems under three different conditions and concludes that PER of the gas engine heat pump is highest.The optimum selection of feasible heating and airconditioning systems is not to be influenced only by a single factor,but by several factors,many of which can not be calculated and are ignored sometimes.That will lead to a deviation in making a decision.Based on the multiple objective decision and evaluation method,this paper evaluates six heating and airconditioning systems in regard to environmental impact,cost and performance and so on,then gives some suggestions on application.This method can conduce to making scientific decisions for projects.
