Because of the particularity of its function

the decoration design of the computer room needs to take into account the requirements of cleanliness

fire resistance

electrostatic protection and energy efficiency

and is closely related to the form of air supply and air return of HVAC. Based on the GB 50174-2017 Design Code for Data Centers

this paper analyzes the selection principles for decoration materials of computer room and the influence of different air supply forms of air conditioning on decoration schemes. By examining the characteristics of underfloor air supply

horizontal air supply of in-row air conditioning

small wind wall air supply

and indirect evaporative cooling HVAC air supply

the study summarizes critical decoration considerations

such as raised floor height

ceiling design

and cold/hot aisle containment strategies under various air supply modes. Meanwhile

based on actual cases of education institutions

enterprises and large-scale operator computer rooms

the differences in wall/ceiling/floor decoration methods among different-sized computer rooms are compared. The research demonstrates that the decoration design of the computer room needs to take the air distribution of air conditioning as the core. Through reasonable planning of cold and hot channel isolation

material selection and structural optimization

efficient refrigeration and energy consumption control can be achieved

which provides theoretical and practical reference for the construction of computer room.
