上海大的空调系统设计+CAD图纸(2)
Design instructions
This design for the Shanghai grand hotel air conditioning system, the construction area of 4166.36 square meters, with meeting rooms, guest rooms, etc. Mainly for design and improve the indoor environment and air quality. The hotel air conditioning design mainly around the "health, energy saving, comfortable" this one theme, the basis from the air conditioning system, as a temperature, humidity, clean air, and air circulation control system, it is inside a building played a vital role. And for a living environment, indoor air temperature and humidity, cleanliness, and the importance of air quality. So, the living conditions and air conditioning requirements, and refer to the related literature material made this plan. In this building have a basement, so should set up a water chiller in the basement. Floor design adopt fan-coil unit plus fresh air system, each layer has a fresh air units, can be provided fresh air unit into indoor, fan coil units to undertake indoor hot and cold load. Water system USES the level with the program, the vertical different programs, basic to implement low cost, easy structure, and the purpose of the cleaning.
In order to increase the comfort of the hotel to live, adopt fan-coil unit plus fresh air handling and fan coil units to undertake indoor full load, and fan coil completely independent fresh air system, set up the diffuser independent type of outlet, each floor a fresh air unit burden the layer set up all the fresh air of air conditioning room, the fresh air unit with heating, cooling, humidification, dehumidification, filtering, and other functions, the air conditioning system has the advantage of occupy less floor area and centralized cooling and heating. At the same time each terminal equipment have independent switches and adjustment function, each the temperature of the room alone can regulate and control. Part adopts a closed water system, dual control program system.
Design content includes: the selected appropriate type of air conditioning system and determine the design scheme of calculation section is also very important, for example: air conditioning cooling load calculation; The pision of the air conditioning system and the scheme of system; The design and calculation of the wind system; Indoor air supply way and the selection of airflow organization form; The design, layout and hydraulic calculation of water system; The design of the duct system and pipe insulation, etc. In addition, also need to be air terminal and auxiliary equipments and the selection of processing equipment. Need to combine the characteristics of the choice of air conditioning systems and to choose the appropriate structure of the office building of the air conditioning unit and terminal equipment, within a reasonable decorate condole carries on the duct and the location of the pipe.
The most basic use of air conditioning system is to keep the indoor relative humidity and temperature in a certain range. The temperature of the air conditioning room base means it requires the lowest temperature. The minimum relative humidity of air conditioning room is the base of the relative humidity of the room. Precision air conditioning room to allow the temperature and relative humidity fluctuations in value.
The air conditioning system to design the big sheng hotel is located in Shanghai, the total land area: 1118.8 square meters, total construction area is as follows: 4166.36 square meters, building maximum height of 7.2 m. A total of 3 layers on the ground, underground 1 layer, the main purpose is to accommodation.
The design standards in strict accordance with the state issued by the relevant standards and specification specified in details, including indoor design the main parameters are as follows:
Conference room: dry bulb temperature of 26 degrees Celsius in summer, winter dry bulb temperature is 20 degrees Celsius, for fresh air volume after 30 m^3/h * p.
