Cold And Heat Source Design Green Company Office Building
Abstract: The project is located in Shanghai, for the air conditioning system of Green
company office building design, the building has five floors, four floors on the ground, the
underground layer. Underground layer of equipment room, 1 ~ 2 layer for Office Area, the 3
layer is the staff canteen, kitchen and staff quarters and so on; the 4 layer is mainly used for
placing a ceiling, cooling tower and water tank. This design is mainly aimed at cold and heat
source design: including load calculation, scheme comparison of cold and heat sources, design
of cold and heat source equipment, smoke control design room. Cold and heat source for the
chiller and heat exchanger, cold and heat source and water system all adopt different
regulation two control, smoke control design, the room is pided into two smoke pision
each smoke zone are respectively provided with a smoke outlet, smoke into the exhaust
manifold by the smoke outlet, and then turn to the exhaust duct, into the exhaust fan to exhaust
rendezvous with the ground layers be discharged.
Keywords: load calculation; heat source; smoke control
