阳明大厦中央空调系统设计+CAD图纸(2)
According to the diagram given room number building conditions to determine the load of each room type, room size, window size, envelope heat transfer coefficient, toward the room, the heat transfer area, outdoor weather conditions, and interior design parameters. Excel table to the room with the hourly load of statistics calculated; appear to determine the maximum load and maximum load value of time. According to the design standards of energy conservation, combined with calculation software, cooling coefficient method used throughout the hotel on the hourly cooling load calculations.
The design requirements based on meteorological data and air conditioning in Shanghai, the business district special room fan coil plus separate rooms using a new air conditioning system, which can meet different functional room staff use the time period of the activities of the different requirements, flexible layout, easy to control. The new spaces are all air system with full fresh air ventilation heat exchange unit, so you do not waste too much energy. Office area and a large hall for staff more space under the load of air-conditioning and air volume is large, easy to set up an
independent air system air-conditioning, full air constant air volume system is easy to eliminate noise, filtration and purification and air conditioning zones of temperature and humidity control, and airflow stable, relatively suitable for applications requiring high technology of air conditioning systems.
In the design the new air intakes the fixed waterproof shutters in order to prevent flood water from entering. According to the actual situation in the office building, offices and corridors use square diffusers, the lobby organization use lateral air flow and select double-outlet louvers. Return air ducts are fixed in the ceiling .The advantages of duct layout is to reduce investment and does not occupy floor space. Moreover, it is easy to decoration and coordination.
The design elements include: hot and cold air-conditioning load calculation; air-conditioning system and the determination of proof; air supply and air supply parameters of the determination; selection of air-handling equipment; airflow calculated; hydraulic calculation; other equipment of choice; thermal insulation and vibration and noise reduction, and other content. The design for commercial and office buildings of air-conditioning system should be combined the characteristics of itself. The airflow speed, temperature, humidity should reasonable. Staff will feel comfort in this circumstance. This is benefit to get better work efficiency. So take full accounts of reasonable air flow, temperature, humidity and pressure control, energy conservation measures and automatic control system to make the design more reasonable, more in line with national norms, to meet the requirements of owners.
