【正文】 airconditioning in summer. The groundsource heat pump was used as the auxiliary source. The type of solar collector used in this part is evacuated tube solar collector, integrated with flat roof. The total amount of solar collector is ㎡ 。 5. The Uvalue of the windows is 2mWK? 6. The Uvalue of the door is 2mWK? According to the simulation result with Trnsys, the energy efficiency in building of this project is 65% pared with pat public building in China and is higher Chinese standard. 3. SYSTEM DESIGN North Part Solar heating system supply energy for space heating in winter, the groundsource heat pump was used as the auxiliary heat source. In the season except winter, solar system store the heat in the concrete tank, the volume of which is 2003m .In winter, the groundsource heat pump and storage tank meet the cooling demand together. The terminal system for space heating is radiator and floor heating system. To make full use of the energy from solar system, Firstly, the higher temperature water from solar system pass the radiator, then go into floor heating system. The type of solar collector used in this part is flat plate solar collector, integrated with external wall。 3. The Uvalue of the roof is 2mWK? 。TWO DEMONSTRATIONS OF SOLAR HEATING AND AIRCONDITIONING SYSTEM IN BUILDINGS IN CHINA Zhang Xinyu, Zheng Ruicheng, Feng Xiaomei , Zou Yu, He Tao ,Xuwei ,Zhang Jianghua,Li Zhong China Academy of Building Research , Beisanhuandonglu Beijing 100013, China ABSTRACT Two demonstrations of solar airconditioning and heating system in office building are introduced, one is solar heating system with seasonal storage, flat plate solar collector integrated into external wall, the solar fraction for space heating is 25%, another is solarassisted airconditioning system, evacuated tube solar collector integrated with flat roof, the solar fraction for space heating is 20%, for airconditioning is 50%. The auxiliary energy equipment is groundsource heat pump system. The control strategy for solar system and auxiliary energy system are also introduced. The project is financial by National Renewable Energy Fund of China. 1. INTRODUCTION The demonstration project located in Tong Zhou District of Beijing which near to Beijing Capital International Airport. The project invested by China Academy of Building Research, is the national demonstration project for energy efficiency in building on city level. The total construction area of the project is 9460 3m , divided into two parts. One is 2835 3m , named South Part, another is 6625 3m , named North Part. The flat plate solar collectors integrated into external wall with seasonal storage are used in the South part. The evacuated solar collectors on the flat roof are used in the North Part. The function of the building in project is office and tes
