| Currently,there is a strong tention between energy and society development.Our country consumed 335 million tons of standard coal in the year 1996,it had a percentage of 24 of all the energy consumption.In the year 2001,it has increased to 376 million tons of standard coil,increased by 0.05% every year,and had a percentage of 27.6% of all the energy consumption.From the year 2000 to the year 2015,with the development of civil architecture the proportion of energy consumption will continue increase.Generally about 40% to 50% of building energy is consumed in air conditioning system.The energy saving of building and HVAC system has become an urgent problem to be solved in our country.The HVAC system did not work well in yifu library of Beijing university of technology,so we have a local investigation.Finally we found out the reason for"cold in winter and hot in summer".In May eighth,we tested the temperature of reading room,office;supply and return water temperature;water flow and the velocity of fan coil units.We simulate the library with EnergyPlus,which is developed by U.S.A,compared the simulation results with the true temperature and they anastomosed well.On the basis of good simulation results,We simulate the hot day in summer and the cold day in witer and get the temperature of the reading room and the office.For the bad thermal environment of zone0 glass cuitain wall,the author read a series of different glasses and their parameters. The author simulate thermal enviorment in floor 2 with different glass combination, get their infection to people's thermal comfort.We suggest to rebuild the glass curtain of zone0 to satisfy people's thermal comfort and realize energy saving run. In our investigation,We found the unreasonable of the HVAC system in the library and analysed the possible energy saving run.The author simulate different energy saving measures and get the load change.Compile programe with WebCTRL to...
