2 The general situation of the engineering
The project is located in Shanghai City, is a high-rise luxury hotel, a total construction area of 10261.82 square meters, building height of 22.2 meters, the whole building from the dining-hall, bar, swimming pool, sauna room, room four parts. According to the construction condition, Lobby, restaurant, bar and swimming pool in one to two floor to use the entire air system, and the small area room in one to two layer and guest rooms in three to six layer adopt fan-coil unit system, at the same time in order to ensure the supply of fresh air, use the fresh air system independent.
3 Discipline of design
Design of indoor temperature and humidity parameters based on energy principle, according to the space use by HVAC design specifications and design manual selection. Parameters of the building area and space use, equipment layout and other specific circumstances see building materials.
Dining-hall: The summer temperature of 24 degrees, relative humidity is less than 65%, the winter temperature of 22 degrees, the relative humidity is greater than 40%, fresh air volume is larger than 25m3/h.p.
Guest room: The summer temperature of 25 degrees, relative humidity is less than 60%, the winter temperature of 23 degrees, the relative humidity is greater than 40%, fresh air volume is larger than 40m3/h.p.
Entertainment facilities: The summer temperature of 24 degrees, relative humidity is less than 65%, the winter temperature of 20 degrees, the relative humidity is greater than 40%, fresh air volume is larger than 30m3/h.p.
4 The main work of design
Design documents containing the design specification and design drawings of two parts. The specification part of design systems should be on the basis of the guiding principles; The scheme of design and its advantages and disadvantages; Determination of design parameters, equipment selection, to determine the design technological scheme should be comparison. Design calculation shows that the computational part containing the air quantity calculation, hydraulic calculation of ventilation pipe and related selection. Design drawings should be able to reflect the integrity of the design, drawings will be the use of computer graphics. Drawings shall include directory, design specifications, main equipment and materials list, system diagram, plane layout of pipe and duct and so on. Chart font, the title bar in accordance with the unified provisions, legend and drawing method of implementation of the relevant national standard drawing.
5 Basis of design
Request access to the literature is the latest, effective standard, specification and books. The main references:

6 Air conditioning water system
The construction of low-rise buildings, based on taking into account issues such as energy saving and clean pipe, so the closed system, which not only makes the pipeline is not easy to dirt and corrosion, the system does not need to overcome hydrostatic head, pump power and smaller. Because of the two control methods are simple and low initial investment, and the building is located in Shanghai, without the need for both cooling and heating and no special temperature requirements, so the two control system. And the use of different programs.
7 Air condition breeze systems
According to the construction condition, Lobby, restaurant, bar and swimming pool in one to two floor to use the entire air system, and the small area room in one to two layer and guest rooms in three to six layer adopt fan-coil unit system, at the same time in order to ensure the supply of fresh air, use the fresh air system independent.
