Abstract
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.
After the completion of the program is determined, the calculation of resistance of the air system and water system should be started. In the calculation process, the comprehensive economic factors, quality factors to determine the pipe to determine the path of the duct hose pipe to draw the most unfavorable path of resistance, combined with the cooling load, air supply, select the corresponding end of the air-conditioning products as well as auxiliary equipment.
We find a variety of manufacturers in the design process, product samples, get to know today's professional manufacturing level, and follow HVAC design guidelines and regulations, discuss the problems encountered in this design, and lessons learned. According to the design process and calculation results, use the CAD to draw standard layer of air-conditioning system plan, water system, wind system diagram, Axonometric.

The general illustrate of design
1 The source of the design
In order to meet the needs of international trade, tourism, and the rapid development of city construction, development of high-rise building will not stay in the level of development of the past, especially and comfort of buildings within the air quality requirements will increasingly high. The new medium and large commercial buildings have installed air conditioning system, in order to improve the grade of shopping malls, attract more customers. Commercial building increase continuously, and people have more and more attention on the indoor air temperature and humidity, cleanliness and air quality problem. So there is an urgent need for commercial buildings installation of energy-saving, health, comfortable central air-conditioning system to meet the high level of life pursuit.
The design is for the comfort of ventilation and air conditioning design, the main task of this design is : air conditioning system selection and arrangement, load calculation of indoor thermal, system hydraulic calculation, air flow of system and heat balance calculation, calculation of the relevant equipment selection and so on. Design results include the relevant drawings and specifications. Through this design can control air conditioning design steps, content, as well as the standard to follow, and put into practice.
