Commercial buildings continue to increase, as well as people on the temperature and humidity of indoor air, cleanliness and air quality issues more attention. Due to energy shortage, saving more and more people pay attention. There is an urgent need for commercial buildings to install configure energy, health, comfort, central air conditioning system to meet people's pursuit of high living standards.
Currently, with the gradual growth of China's economy, improve people's living conditions are increasingly comfortable living environment demands increasingly high demand for the growing central air conditioning, central air-conditioning energy efficiency, comfort, health more attention. Therefore, the design an energy-efficient, comfortable, healthy central air-conditioning project is very practical.
The design for the Sung building of Shanghai central air conditioning system aims to provide a comfortable working environment for the workers inside. Design elements include: air conditioning cooling load calculation; determining an air conditioning system partition and system solutions; air-conditioned terminal handling equipment selection; design and calculation of wind systems; indoor air supply and air distribution in the form of selection; water system design, layout and hydraulic calculation; design duct work insulation and plumbing systems; muffler vibration-proof design and so on. The design is made according to the relevant specifications to consider energy efficiency and comfort requirements, building zone air-conditioning system using VAV air system-wide, the podium of all-air systems mall area, lounge and a number of other small space using air fan coil system. With several air-conditioning systems used in combination, the maximum extent to meet the comfort
requirements of people in the room and achieve energy saving.
In short, with the advances in technology and society, energy saving, environmental protection, health, intelligent control has become a major trend in the development of air conditioning.
Air conditioning system design is a comprehensive strong work, it requires not only designers to master the theoretical knowledge and have some experience, but also requires the designer to master the methods of the professional engineering design, procedures and relevant regulations, standards and therefore it must be treated seriously. An air conditioning project success involves many factors, should conduct a comprehensive analysis, the correct design and calculation. To ensure the safe operation of the air conditioning system in the economic, reasonable, energy conditions, the designer in the design, must be ready before the air-conditioning engineering design, and a more detailed understanding of the air-conditioning engineering design content, procedures and related design documents.
Because I am a graduating college students, I am still relatively weak in both practical experience and theoretical basis. Inevitably there are errors and deficiencies in the design process, I implore you teacher correction.
