Title HVAC design of complex building of nanning

Abstract This design is about the concertrated air conditioning system of complex building , including a series of design contents such as cooling load calculation, scheme comparision,selecting and calculating the water system and ventilation system, as well as selecting air terminal devices and appurtenances, and working out the design instruction and drawing the construction drawings employing CAD。 According to energy-efficient design standards , the cooling load of the whole building is calculated with the harmonic wave method, combining to computer software。 Water cooled screw rod unit is used to supply the cooled air conditioning water, while using gas-fired hot water boilder as the heat source。 This scheme is determinated according to the feasibility analysis and economical comparision of different choices, energy policy ect。 Fan coil unit and the independent fresh air system is the main choice in the design。 Based on the design, further comparative analysis of impact of different architectural envelope thermal characteristics ,design parameters, air conditioning scheme on the energy consumption 。 Points out the energy consumption fearturesand the potentials of energy saving。
