Abstract
　　　This design is about the concertrated air conditioning system of some Technology 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. During the design , I adhere to sustainable development ,set a scientific conctept of resources and a total life cycle cost analysis. Based on the energy conservation and environmental protection ,I consider intergatedly into the building structures ,the feature of demands ,and the environment conditions. Some energysaving measures are adopted during the choice of system scheme ,equipment matching and operational control to achieve high efficiency in various operating conditions . 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.
　　　
Key words: comfortable air condition,sustainable development,building energy efficiency,in door air quality
