Air Conditioning Design of Shanghai Huaxin International Hotel
ABSTRACT
The air conditioning engineering of the -1F and 4F of Shanghai Huaxin International Hotel was designed. On the base of cooling load, heating load and moisture load calculation, primary air fan-coil system and all air system are adopted by way of technical and economic analysis. The fresh air doesn’t undertake indoor load and delivers air through double deflection grille after mixing the return air in the horizontal recessed fan coil. The return air is harnessed one time by the air handling unit in the all air system and the handled air is delivered through double deflection grille by sidewall air supply. The fresh air is supplied by hole or shaft and handled by the fresh air handling unit. The chilled water which is a closed two-pipe direct return water system is supplied by the refrigerating plant room. The thermal insulation material of water pipe and air duct are foam plastics and centrifugal glass wool respectively. Measures of noise elimination, damp, fire prevention and smoke extraction is considered during the design.
