Design general description
The design of Boan commercial building area of air conditioning and ventilation system design, the building is located in Shanghai, is building a 11 storey multi-storey buildings, where the underground 2 layer, to 11 layer. Building height of 41.8 meters, with a total construction area of 34798.4 square meters, of which two underground refuge floor, the ground floor for the dining area, on the ground one to four for the commercial area, the five layer to the eleven layer for the office area. Inside the front desk, toilet, storage room, fire room, office, office, conference room, etc Interior design requirements: with comfortable type air conditioner indoor calculated parameter, the beginning of design: Summer: dry bulb temperature is 25 DEG C, relative humidity was 75%, 0.2 meters per second wind speed; winter: dry bulb temperature for 25 DEG C, relative humidity was 75%, wind speed is 0.2 meters per second. Collected relevant information on design, air conditioning load calculation. (including wall, fresh air, people, lighting and equipment load) the building is located in Huangpu District, Shanghai City, a commercial building, external flow is large, internal flow is increased, in the bustling commercial lots. External air quality because of the large population density and appear chaotic, atmospheric pressure is lower than the average of Shanghai city. Therefore, the construction of the external environment is not ideal state has improved, improve air quality and bring people comfort.
Meaning of energy-saving building is according to the climate and energy saving grass-roots solutions, planning for the construction of partitions, relatively low energy buildings, it is an important index of, construction planning and layout for natural ventilation more convenient, greening rate should not be less than 35%; building maintained between the household has at least a living space in the coldest winter when get full window sunshine 2 hours, and so on. The building needs to meet the above requirements.
Boan commercial building area of air conditioning and ventilation system design of the meaning is, building energy conservation is is one of the important part of the work of energy saving in our country, is a complicated systematic project, which covers the planning design and construction of energy-saving products of multiple links, even extended to the whole building full cycle. Building energy efficiency is now the foundation of economic development, but also the premise of reducing atmospheric pollution. Building energy efficiency can also improve the quality of the thermal environment, with the development of modernization and the rise of the level of national living, comfortable building thermal environment has gradually evolved the necessities of life for adults.
This time the Boan commercial building area design, comprehensive consideration of various factors, through calculation and test, repeated visits, and ultimately determine the the building's air conditioning system for fan coil unit plus fresh air system, the project has many benefits and convenience. Not only improves the convenience and flexibility of the operation of the air-conditioning system, has well weakens the commercial itself shortcomings, foster strengths and circumvent weaknesses, meet the indoor temperature, moderate, relative humidity and wind speed. Considering the down, this program very much in line with Boan building business district construction requirements, to maximize meet people comfortable and beautiful. In the function of the room, the whole building adopts the fan coil unit and the independent fresh air system. In the aspect of the wind system, the fan coil carries all the cold load and part of the fresh air humidity load. The heat transfer coefficient of building envelope, the outdoor weather condition and the interior design parameters are determined according to the building condition map. According to the requirements of the design standard for energy efficiency, combined with the calculation software, the calculation of the cooling load factor method of whole Boan commercial building area cooling load by. In the design of indoor heating and air conditioning, according to the calculation method of hot and cold load calculation of the thermal load of the building envelope, respectively, to calculate the heat load of the building. 商业区域空调通风系统设计+CAD图纸(2):http://www.751com.cn/gongcheng/lunwen_41427.html
