Build 13 tiers in total originally, mainly used for the hotel, as well as office functions, the basement room for the underground Tingche Chang and equipment. Designed strictly in accordance with the specifications, design manuals, technical measures design, design load is included in the calculation of hot and cold wet, wind calculation, equipment selection, duct water resistance calculation, the choice of outlet, air flow calculation, ventilation, fire row smoke, chiller plant design and system layout. Combine the characteristics of this building, with a full air and air fan coil air conditioning system forms . Each floor of the hall is a return air all air systems, indoor air levels with square air diffuser means. Layers of the small area of the room with the air fan coil airconditioned form, use air fan coil system, which is relatively small air volume, air duct, small size, easy layout, installation. Horizontal concealed fan coil is used to double shutter inlet port. The new air shaft from the hole in the wall or the introduction of fresh air, room air by the new focus on the new air supply unit. Chilled water supply from the bottom of the freezer room. Smoke control system in strict accordance with standard design and verification, and the bination of exhaust design, using the same system, toilet, underground garage, underground equipment areas such as mechanical ventilation.. Keywords: airconditioning air fan coil system, full air system design 沈陽工業(yè)大學(xué)本科生畢業(yè)設(shè)計(jì) I 目 錄 摘 要 .....................................................................................................................................
