General Information Design
The task of the subject content
This air-conditioning systems design is 3M Hefei Phase I（Solar Battery Backsheet/Abrasive Product Project）, according to the basic theory and professional knowledge, combined with practical engineering, in accordance with the engineering design specifications, standards, and independently completed the required engineering design. Includes design specifications and design calculations in two parts. Design specification should include: design basis and the guiding ideology; design form and the advantages and disadvantages of the system; Parameters, etc., should determine the design of technical, economic comparison instructions. Design calculations to have the necessary calculations; computing content should be given to its source; finally completed building the data center air conditioning system design. Design drawings should reflect the design of a complete overview of all the drawings using computer graphics. Description should include the design and construction drawings, the main equipment and materials list, the system, plans and so on.Legend and the drawing of the execution of national mapping specification.
1 Design of the main
According to the nature of the building, use and construction unit requirements, the South Building, A specific design areas are as follows:
(1) load calculation: the main room of the hourly cooling load calculations, air conditioning equipment as the basis for calculation and selection.
(2) the calculation of air-conditioning equipment selection: the selection and calculation, including fan coil units, air conditioning units and air units in the selection of a new calculation. In the selection process to meet the "heating, ventilation and air conditioning design" (GB50019-2003) requirements; in the selection process should be based on the use of the building, size, use the characteristics of an investment as far as possible the conditions Province, the system runs the principles of economy and reduce energy consumption.
(3) air conditioning duct systems design: choose according to the actual situation of the building's air system;
(4) air-conditioning water system hydraulic calculation and wind systems: the water system and water system, including the most unfavorable pipeline design, fan coil units and air conditioning layout. This is the air conditioning system design, a very important step.
(5) the use of CAD drawing software will bear Marine Garden Tower, Shanghai to conduct a complete and comprehensive air-conditioning system design, and meet graduation requirements.
