Energy Consumption Simulation And Analysis On An Office Building With Intermittent Air Conditioning In Hot-summer And Cold-winter Zone

Office building is a main part of domestic building which symbolized the rapideconomic development of our country. Some elements exacerbated the buildingenergy-consumption in China, such as,the ever-increasing of working area in officebuilding, the growing demands of comfort, as well as the arbitrariness and barbarismof users’ behavior in environmental control system. Therefore, apart from thebuilding energy conservation itself, studies on guiding human behavior is a majordirection of development of building energy efficiency. According to the statistics,heating and air conditioning accounted for a large proportion in building energyconsumption, so, guiding people’s utilization behavior through the use ofenvironmental control system can effectively reduce energy consumption. In thispaper, DeST-c energy simulation software is adopted to simulate a gall ery-styleoffice buildings in Changsha, within the simulation and analysis of intermittentoperation mode of air conditioning. The energy efficiency and comfort of intermittentoperation mode of air conditioner have been explored and this paper discussed h owchoosing air conditioning running mode affects the optimal energy efficiency andcomfort issues if a room in different directions.In this paper，seven kinds of air conditioning operation modes are consideredincluding the continuous and intermittent mode. Detailed research and analysis onenergy consumption and room temperature about air conditioning room on the samefloor in different directions and different floors in the same orientation on whichcarried seven kinds of air conditioning operation modes, behavior guidelines isobtained to guide the staff using air-conditioning mode. Firstly,compared withcontinuous operation mode,all air-conditioning intermittent operation modes have acertain energy saving effect, this modes have different consequent of theair-conditioning energy-saving effect and comfort for different room: in addition tothe afternoon mode is the best mode for the room with East external envelope, patternin the morning is the best comprehensive effect of the air conditioning intermi ttentoperation mode. Secondly, simulation results show that when the same floorair-conditioned rooms in different directions carried out intermittent operation mode,the more energy a room consume originally, the more obvious it can reach energysaving effect when it is intermittent operated., And the room’s indoor temperature has great relationship with its position. Such as, the room with East external structure andinterior heat experienced a huge temperature raise when it carried on intermittentoperation mode; When different floors air-conditioned room in the same directioncarried on intermittent operation mode, the order of the room energy consumptionfrom a maximum to a minimum level are: the top floor, the ground floor, the middlelayer, and its temperature is also the same trend. Finally，considering the effect ofenergy efficiency and comfort, the optimal comprehensive effects can obtained forrooms in different directions on different floors. For room effect, when the room onthe ground floor carried on intermittent operation, the comprehensive effect is thebest.For the entire building effect, due to the interaction between rooms thecomprehensive effect is the best, when the middle layer of the room air conditioningcarried on intermittent operation..The results obtained in this paper not only can be used for guidance personnelsaving behavior, also to guide the building designers and managers to design and usethe room for a reasonable arrangement, the conclusion has certain extension.
