The graduation design topic is the end of the Central Science Bookstore B zone air conditioning system design, as described above for more than half of the energy consumption of HVAC accounted for the total energy consumption of the building, energy consumption of this part of the most used for heating and cooling system, so the control of energy consumption of cold and heat source system is an important aspect of reducing building energy consumption. Fan coil plus fresh air system is pided into two parts, the central air-conditioning fan coil unit and fresh air system, fan coil is the end of the central air-conditioning equipment, air system cooling load to meet the burden of indoor air quality, fan coil plus fresh air system is an important form of air conditioning water system, the air conditioning form more common is the private building. With the development of modern science and technology and the economy of our country, people's living conditions have improved, and the comfortable request to the living environment of the higher demand for central air conditioning, more and more. The total energy consumption in China's building energy consumption of 27%, and is increasing by 1% every year. In general, fan coil plus fresh air system has the following advantages: (1) flexible control, has advantages of inpidual control, can flexibly adjust the room temperature, according to the room used to determine the status of the fan coil units start and stop; (2) fan coil unit, small size, small occupation of land, convenient layout and installation, and is suitable for the old building; (3) easy to implement the system partition control, cooling and heating load according to the purpose of use, the use of room, time of the system is pided into several regional system, the implementation of zoning control;
The design of each room fresh air load, heating load and moisture load made with precise calculation. By Hongye load calculation software calculated load to hand count check. As chiller selection, selection of pump, hydraulic provides full and accurate basis calculation.
The design of the cooling load is 1691.4KW, this design also focused on the advantages and disadvantages of different air conditioning systems and selection. Then compared the all air system, air - water system, water system, to compare different system from the technical economy and the Shanghai region's energy situation will ultimately determine the cold and heat source system, the design of the selection of fan coil - the air system system forms the most economic and reasonable.
KeyWords：Fan coil； primary air system
