The design of the main reference standard for the heating, ventilation and air regulation design specification "," code for fire protection design of buildings ", the top civil building code for fire protection design of (2005 Edition), the fan coil unit", "building ventilation and smoke exhaust system with fire-proof valve".

This design combined with the impact of the surrounding buildings and the construction of the actual situation, the central air-conditioning design. Tectonic characteristics and applications considered in this design, the indoor environment comfort and operation management convenient and energy-saving facilities and economy, various factors, the fan coil plus fresh air system independent air conditioning design of the building. This can meet the different functions of the room to use the time period of personnel activities of different requirements, the layout of flexible, easy to control.

The design of the cold and hot load first, then determine the form of air conditioning system, terminal equipment selection, and then carry out the plan, after the calculation of the water pipe and the pipe diameter, complete the plan design. Air conditioning system design also has insulation and corrosion protection design, sound insulation and shock design, ventilation and smoke exhaust system mainly based on the relevant national standards for design considerations.

This engineering design part mainly uses the personnel office area. Fan coil unit plus fresh air is used to deal with the air. Because the building is located in Shanghai, from the office of the use of functional point of view, cold, hot demand to meet. The time period of the design of the air conditioning system of the building is opened by 8 hours.

The design content mainly includes: (1) the meteorological parameters of the collection project. (two) cold load wet load (worst case). (three) to determine the program (four) the calculation of air flow (1, according to the load and temperature determine the status of point 2, determine the minimum fresh air volume 3, according to the air conditioning mode of air distribution and air distribution). (5) air conditioning water, air system design (1. First, the layout of air conditioning duct, followed by a wind system of hydraulic calculation, to determine the diameter and the resistance of the corresponding content 2, first to arrange the air conditioning water pipe, second, the water system of the hydraulic calculation, determine the diameter and the resistance of the corresponding content). (6) of the main air conditioning equipment design and selection of (1, in accordance with the air processing plan, and combined with the psychrometric chart, to air conditioning equipment selection, design and calculation of 2, to further determine the air treatment equipment capacity and supply air volume, determine the air processing equipment structure and thermal parameters of numerical 3, according to the air duct system hydraulic calculation to determine the flow of the fan, wind pressure and types). (7) ventilation and smoke, smoke exhaust system design is (1, determine the ventilation scheme calculated system required ventilation volume, primary fan 2, arrangement of the ventilation system piping and equipment calculated pipeline resistance, determine the diameter, selected fan types 3, to determine the protection, exhaust system is set up for the site, choose plates, exhaust, smoke prevention and exhaust design).

Through this design, let us learn the professional knowledge of the professional. Step by step to complete their own design, develop their own ability, for the future work to lay a good foundation.
