Title The HVAC Design of an Office Building in ShangHai
Abstract
This project is the air conditioning system design of an office building in Shanghai. an underground floor of the building, 22 floors above ground, including podium four-storey，the height of 89.6 m in total, with a total floor space of 37635 square meters, is the first class building. The design used air source heat pump as cold and heat sources. Large spaces such as business hall, commercial bank hall, entrance hall, used all-air system. offices and commercial space, primary air fan-coil system is used. Water systems with closed- loop direct return system. Ventilation taken out by the exhaust fan in bathroom, installing check valves at the end. Stairwell use of positive pressure ventilation systems; basement 1 floor, the long corridor of above ground set the smoke control system, variable-speed wind turbine selected by basement 1 floor ,exhaust peacetime, exhaust smoke when the fire.
Main works in the design process include: Comparison and determination of air conditioning system; Calculation of building cooling , heating and wet load .The layout of Air conditioning system. The selection of air conditioning end equipment and accessories. Hydraulic calculation for air conditioning system. Design and layout of ventilation system. engineering drawing.
Keywords air conditioning system air-source heat pump all-air system primary air fan-coil system
