ABSTRACT
This project is about construction of ventilation and air conditioning design in Galaxy Mansion of Xi’an. The building has basement, and seventeen floors over ground. And, the overall floorage of it is 17,373 ㎡ in which 10,700 ㎡for design. Basement for the equipment room, the main building of 1~9 layer for office space, the 10layer is a sky garden, 11~17storeys for residential building. The skirt building has three floors, and all securities companies operating room. The central air conditioning design range is the main building1~9layer office and the skirt building 1~3layer for securities business district.
The project total cooling load of air conditioning in summer1,417kw, one centrifugal chilled water refrigerating machine is employed as the cold source of the conditioner(single cooling capacity of 1,400kw ).The total heat load in winter is 1,134kw, and the municipal heating network to provide heat source. through a plate heat exchanger heat exchanger for air conditioner in winter heating ( heat transfer for 1,163kw ) . Air conditioning machine room located in the equipment room of the basement.
The project of central air conditioning systems: main building1~9 layer and skirt building 3 layer for fan coil and primary air system. The skirt building 2 layer for hanging air transact unit and primary air system. The skirt building 1 layer is adopted with all-air system , use the hanging air transact unit.
The water system use two-pipe water system, divided into 3 zones, the main1~3layer for A area,4~9 layer for B area; foundation1~3layer for C area. Risers using direct return system, each layer using reversed return system.
The construction of the basement of main equipment room and hallway to take mechanical design of. As positive pressure air supply smoke control design is adopted in stairwell, the antechamber and common antechamber of staircase , ensure the stairwell
