摘要
为了尽可能降低大型公共建筑内空调系统运行的能耗,以北京大兴国际机场为例,通过采用温度控制和平均热感觉指数(Predicted Mean Vote,PMV)控制机场公共建筑的集中空调系统,进一步对舒适性和节能型进行对比分析,指出不同的控制方式对人及空调系统的影响,基于此提出节能措施以降低空调运行能耗。结果表明,从单个房间来看,PMV能耗指标较高,但是从整体来看,总的能耗是降低的,这也说明采取PMV方法来控制系统能耗是可行且较优的;基于此也给出了相应的节能改善措施。为今后降低建筑集中空调的能耗,以及其他机场建设提供一定的思路。
Aiming at reducing the energy consumption of air conditioning system in large public buildings as much as possible,taking Beijing Daxing International Airport as an example,the temperature control and the predicted mean vote(PMV)are adopted to control the central air conditioning system of public buildings in the airport.Moreover,the comfort and energy-saving types are compared and analyzed.The impact of different control modes on people and air-conditioning system is pointed out.Based on this,energy-saving measures are proposed to reduce the energy consumption of air-conditioning operation.The results show that the energy-consumption index of PMV is higher in a single room,but the overall energy consumption is reduced,which also shows that it is feasible and better to adopt PMV method to control the system energy consumption.Based on this,corresponding energy-saving improvement measures are also given.This provides some ideas for reducing the energy consumption of building central air conditioning and other airport construction in the future.
