Underground 2 to 1 are the garages ,and underground 3 is machine room and saveing water for living and the fire. Ground 1 to 3 are the markets and the hall for the vistors who come to the hotel or offices, The rooms of F4 to F9 is for working , The10~14 F is a guest room. According to this construction characteristic and to save the place for people , the entire air system is mainly use air fan-coil system + independent new atmosphere system . primary air fan-coil system + independent new atmosphere system is undertakes in the room by the air blower serpentined all cold loads and new atmosphere Part of Wet loads, but the new atmosphere load undertakes by each new atmosphere unit, the new atmosphere processes through the new atmosphere unit to With the room ,and the fresh air is sent into the room directly. Whole heat exchangers + independent new atmosphere system is undertakes in the room by the air blower serpentined all cold loads and new atmosphere Part of Wet loads.In the market,we use large air fan-coil system and independent new atmosphere system.To get blancer air distribution ,we use meditional powers. To make the garages under ground air ventilate the dirty air put off by cars ,we use the fan named youdao.This systerm can improve the efficience of the ventilate system. This design introduced the determination of the system plan in detail, the calculation of cooling and heating load for air conditioning and fresh air, the examination of air distribution, the shaping of equipments ,the Water friction calculation of Water system, the design of the chilling machine room and the arrangement of the system,and the design of the smoke prevention. At the end of the Whole design, silencing device and sh
