Commercial buildings are a large number of public places, indoor air temperature and humidity, cleanliness and fresh air, etc. floating population of customers and malls greatly affected the health of workers. Therefore, the commercial building air environment is increasingly being valued by the business sector. Our health and epidemic prevention departments of commercial buildings proposed health requirements, focus on the larger malls also been monitored for some medium-sized shopping centers have been built to transform the requirements, additional ventilation or air-conditioning equipment additions. The new medium-sized commercial buildings have to install a central air conditioning system to improve the grade of the mall to attract more customers. Major cities frequently accelerated the popularity of central air conditioning systems in commercial buildings
This design is the square central of nanjing with air conditioning system. Nanjing is a central air conditioning system design and squares of this design. Nanjing is a comprehensive building and plaza, located in Nanjing, the square of the ground floor and four on the ground, with a total land area of 42,000 square meters, total construction area of 184,000 square meters, with a total gross floor area of 117,800 square meters. In order to satisfy the needs of comfortable environment in the mall , Adopted centralized cooling and heating of the central air conditioning system, Selecting air-cooled water chillers as a system of cold and heat source, It has the characteristic that  less investment, high efficiency, environmental protection, no pollution, etc. The end part is pided into north and south, The southern district of space for large shopping mall, So using high-power air conditioning box to deal with the air; norths is a small auxiliary office room, Fan coil is used to satisfy eliminate indoor load, System also adopted corresponding measures such as insulation, noise elimination, shock absorption to improve the efficiency of the system. It contains: cooling load calculation; the estimation of system zoning; the selection of refrigeration units; the selection of air conditioning equipments; the design of air duct system and calculation; the estimation of air distribution method and the selection of relevant equipments; the design of water system and its resistance analysis;
The design of the new wind load for each space, cooling and heating load and wet load a detailed accurate calculations. Hongye load by load calculation software then calculated the hand count checked. For the selection, pump selection, the relevant hydraulic calculation provides a freezer full and accurate basis。
Taking into account the architectural features of the mall, the design uses a small room fan coil set as the end of the treatment and conditioning equipment, a large portion of the space were set ceiling air handling box, adjust the volume to meet demand. Set heat source in the basement treatment room, and pumps the refrigerant through the layers to the end of the processing equipment.
Nanjing is central air conditioning and square design of the program has calculated the theoretical analysis, selective central air demonstration program, there are actual drawing installation. Is a complete engineering design examples. Calculation of main cooling load calculation air volume calculation pipeline computing. Cooling load calculations to determine the status of each room air conditions and regulation, as well as loading the whole project. These calculations is to determine the main data room air conditioner to adjust the program. Also the choice of the most important reference data chillers. Air supply and piping is calculated for the actual equipment and piping data.
The design reference literature at home and abroad, the construction manual atlas project examples and so on. . But because of personal design level is not comprehensive, there are many shortcomings. With their own hopes to continue to learn and do the best research in the program. Thank you teacher can give criticism and correction, let me learn more. 南京正和广场中央空调系统设计+CAD图纸(2):http://www.751com.cn/gongcheng/lunwen_12882.html
