摘要
针对当前中国房间空调器领域缺少全面系统地计算空调全生命周期气候性能(LCCP)模型的问题,结合辐射时间序列法(RTSM)与空调系统LCCP计算,利用RSTM法对空调负荷进行动态计算.根据室外温度、城市所处温区和室内人员状态对空调开启条件进行定义,使得空调开机时间更贴近实际情况.通过Visual Studio 2013构造整体的软件模型,分析不同制冷剂、不同温区、不同能源结构、不同生活特性和不同墙体轻重类型对空调系统LCCP的影响.分析结果表明,采用新型制冷剂、环保的电力生产结构和重质墙体,能够有效地减少空调系统LCCP,夏热冬冷地区空调系统带来的温室效应远高于集中供暖地区(严寒地区和寒冷地区).
An organic combination of radiant time series method（RTSM）and life cycle climate performance（LCCP）was proposed regarding to the problem that there is a lack of a comprehensive and systematic model of LCCP in the field of room air conditionings at the present in China.The room air conditioning（RAC）dynamic loads can be accurately calculated through RTSM.The switch on condition of air conditioners was defined through synthetically considering the outdoor environment,temperature zone and personnel status in air conditioning room,which results in the air conditioner operating time being closer to actual situation.A monolithic LCCP calculation model was established based on Visual Studio 2013.Then the influences on air conditioning system LCCP by different refrigerants,different temperature zones,different energy structure,different life characteristics and different construction class were analyzed.Results show that LCCP of room air conditioning system can be effectively reduced by means of applying new refrigerants,environmental energy structure and heavy wall construction.Greenhouse effect created by air conditioning system in ＂hot summer and cold winter＂zone is significantly higher than that in＂central heating＂zone（cold zone and sever cold zone）.
