本设计参考了大量的文献资料，手册图册，工程实例。尽力做到各个方面最好的结合。但是由于相关资料的所限和本人水平的低微，一些疏漏和谬误不可避免，希望能随着自己学习的长进和研究的深入将方案做到最好。感谢各位师长能给与正确的批评和指正，使我能够得到相对更合理的设计方案。
Design General Information
Shanghai Jingjiang Building 5 floors , standard -storey 4.2 meters , ground floor area of 3168 square meters . This is a collection of office buildings , hotels , leisure and entertainment in an integrated building. The building is located in Shanghai. Shanghai, located in China's eastern coastal areas. Subtropical monsoon climate , four distinct seasons , summer and cold winter , spring is short, but due to its location along the coast , the rainy season is more dispersed , with summer rainfall maximum .
Designed primarily for air-conditioning and hot ambient air quality interior design, but it must be designed to fully understand the impact of construction on HVAC requirements and HVAC systems and equipment, buildings and other facilities on the basis of . According to the functional requirements of the building to the owners long-term interests as the starting point , in order to meet the technical , reliable, economical , easy management, flexibility and use of safe and reliable function to adjust the target . The design for the functions and features , and the meteorological conditions and the building 's air-conditioning requirements , refer to the relevant literature to determine the design. Building no suitable place to install a relatively large unit, you can not use the whole air system ; design uses air fan coil systems , each equipped with new air unit , can be fed from the same layer of fresh air indoor unit , fan coil bear the indoor load. Water level in the same system using the program , different vertical programs , this water system has a relatively simple structure , less investment , less prone to dirt and pipeline corrosion .
This design of the main room of the office buildings , mostly small in size , and each room is not connected to each other , so that the selected air conditioning system should be able to achieve independent control of each room , considering the various factors that determine the choice of fan coil plus fresh air systems. Ceiling fan coil arrangement in the room , and embedded concealed form . The centralized system will be set independent fan coil air system , new air handling unit to introduce new air into the indoor air enthalpy from the outdoor , indoor not bear the load . All bear the indoor fan coil cooling load and part load new rheumatism . Independent fan coil air system by the following Louver send and send side .
To complete the selection of the host and on the basis of fan coil cooling load calculation, and by wind, water pipes and water pipes calculate and determine the path of the wind specifications and check the most unfavorable loop resistance and pressure head to determine fan and pumps.
Ventilation design, basement and garage equipment for the space, designed to mechanical supply and exhaust -based, supplemented by a natural way into the exhaust , which is not less than seven times per hour ventilation ; bathroom exhaust fan designed for mechanical ventilation to outside balcony, ventilation exhaust volume by no less than 11 times per hour is calculated ; take into account the issue of smoking in the office , but also the use of mechanical ventilation exhaust fan to the outside of the balcony, the amount of exhaust air volume of 85% . Elevator room and stairwell design pressurized air supply .
The design of the development plan in accordance with the building structure and air conditioning requirements , hoping to meet the corresponding requirements of being able to meet the office comfort. In addition to air conditioning design from scientific rationality and economy , the overall aesthetics and architectural considerations . Central air-conditioning applications in modern buildings , more and more technology is more mature and advanced . Capable of effective management, one-time investment , the latter easy to use and does not take up space efficient buildings. This article is for central air-conditioning design to selection, to check a description of the calculation . Do good combination from the use of sex to scientific economics and then on . Scheme selection is considered as a whole and the overall design idea is the basis for calculating part of the whole design , drawing part is the actual walk with design and construction and installation of pipes linked . Dependent each other three parts are inextricably linked with the whole project . Each part must ensure that scientific and reasonable, correct, and economical.
