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; cold and heat source of choice and selection of equipment; airflow calculated; hydraulic calculation; other equipment of choice; thermal insulation and vibration and noise reduction, and other content.
The design of office building’s air-conditioning system should be combined the characteristics of office buildings. 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.
