楼宇型分布式能源与电空调供能方式对比

Comparison of Energy Supply Way of BCHP and Electric Air Conditioning

为了探究最佳的天然气利用方式与供能方式,本文基于以内燃机为原动机的天然气冷热电联供系统,建立了系统经济性模型,考虑到能源、环境、经济等因素对系统性能评估结果的影响,采用了多目标评价准则方法。以南京某医院建筑为研究对象,从两种不同的天然气利用方式出发,本文提出了天然气冷热电联供方案以及电空调方案,并与该项目可研报告及文献所提方案进行了比较分析,采用多目标评价准则方法对各方案进行评估,探究系统最佳供能方案及天然气利用方式,并研究了天然气价格以及电价对各方案性能的影响。

In order to explore the best way of natural gas utilization and energy supply,a system economic model is established based on the natural gas Combined Cooling,Heating and Power(CCHP)system with internal combustion engine as the prime mover.Considering the influence of energy,environment and economy on the evaluation result of system performance,a multi-objective evaluation criterion is adopted.Taking a hospital building in Nanjing as a object,according to two different natural gas utilization way,the CCHP scheme and the electric air conditioning scheme are put forward,and they are compared with the scheme proposed by one paper and a feasibility study report.The multi-objective evaluation criteria method is used to evaluate and explore these schemes.The effects of natural gas price and electricity price on the performance of each scheme are also studied.
