Abstract
This design is about the concentrated air conditioning system of some Technology building, including a series of design contents such as cooling load calculation, scheme comparison, 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 concept of resources and a total life cycle cost analysis. Based on the energy conservation and environmental protection, I consider integrated into the building structures, the feature of demands, and the environment conditions. Some energy saving 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 builder as the heat source. This scheme is determinate according to the feasibility analysis and economical comparison of different choices, energy policy etc. 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 feature sand the potentials of energy saving.
Keywords: comfortable air condition, sustainable development, building energy efficiency, indoor air quality
