Building five to sixteen layers of air-conditioning area of about 27842.9 square meters, each air conditioning area of about 2320.24 square meters, the total cooling load of about 3625KW. Most commercial center of the upper layer district office room for the office, conference room, storage room, air conditioning, mainly operating time to work during the day time by fan coil plus fresh air unit group this semi centralized air-conditioning system. Fan coil unit and air conditioning system, convenient for independent control, and the wind pipe occupied by the indoor space is less, suitable for office buildings. Using embedded concealed fan coil units, fan coil undertake indoor total cooling load; each layer of fresh air in the engine room set a fresh air handling units, fresh air and fan coil air separate into the air conditioning room, wind pipe mainly using rectangular duct, air supply mode selection is under the blower air supply mode, were choose square diffuser and return air for the double decker Venetian air return. The water system uses two control and program.
Load calculation for each room, chiller, fan coil, air handling units selection; carries on the design to the water system, air system, and hydraulic calculation, determine the wind pipe and water pipe size, check the most disadvantaged loop resistance, air blower and water pump specifications.
Smoke exhaust design, staircase and vestibule by mechanical pressurized air supply, the fan is arranged in the roof; closed in the aisle and room to take measures of mechanical smoke exhaust and fan is arranged at the top of a building, usually exhaust, fire smoke. Toilet set exhaust fan.
This design for undergraduate graduation design. Reference to many documents, specifications, drawings, engineering examples, the theoretical analysis and calculation, and the design scheme selection and demonstration of the project and decorated with the design drawings, is a complete air conditioning engineering design. The main calculation of the design include: load calculation, air quantity calculation, air flow organization design calculation, pipeline hydraulic calculation.
Finally, the air conditioning system of the pipeline and equipment using the muffler damping and adiabatic anti-corrosion measures.
Due to low level of personal, some mistakes and errors are inevitable, design inadequacies also please teachers to give the criticism.
Keywords: air conditioning system, design, fan coil, water system, air system, energy conservation
