Title  Air conditioning engineering design of a display center  in Suzhou                                             

Abstract    The  graduation design is an air conditioning  engineering design of a exhibition center in Suzhou , subject of the exhibition center is  a four stores building, surrounded by a large lawn, the first and second floor in center is used for large Exhibition marketing such as auto show。 The third and fourth  floors are  office and conference room, the local fifth floor room is used for sightseeing , all the rooms are required of air conditioning。 Due to the first and second floor hall open space,choose the full air conditioning system, the third and fourth are the ordinary work room, so choose the fan coil with fresh air systems。

The content of this graduation design includes building load calculation, calculation of air volume, the hydraulic calculation of wind pipe and water pipe, equipment selection, and the design of cold and heat room used by ground source heat pump air conditioning system , and the buried tube heat exchanger 。 The design of the ground source heat pump system should be considered the imbalance of cold and heat load in summer and winter, it is nessary to use auxiliary utility。

Keywords  ground-source heat pump    full-air conditioning system 

          cooling load     hydraulic calculation
