General description of the design
A, project overview
Shanghai Port International Hotel D district (District Office), located in Shanghai City, a total construction area of 5528.76m2, a total of four. Building height of 17.1 meters, one to three layers for the office, including the manager's office, office, financial room, large conference room, auditorium, room etc.. Floors are 4.2 meters; the fourth layer is the engine room equipment rooms, floors to 4.5 meters, with tanks, cooling towers, chillers, boilers, etc..
Two, system design
1. load calculation
1) The building of four floors, including top-level room. 1-3 layer of 4.2 meters high; the 4 layer of 4.5 meters high. Outside the window height is 1.8 meters, air-conditioning the use of an area of 2496.57㎡.
2) The need for air conditioning area: general manager's office, office, office, lobby manager, financial room, large conference room, auditorium.
3) Fresh air volume according to personnel density, 30m ³ /h.
