The paper requirements designing a reasonable heating and smoke control system for building which according to civil engineering and other relevant information .At the same time , the paper design a district heating station which must rationalization . The project about heating requirements metering heat for the users. The Design of heating choices downfeed and direct return riser system which based in construction of the specific circumstances form. The house heating system using radiators doule pipe reversereturn system indoor. The purpose about distribution arrangements in the system are to simplify the system, saving pipe, buried underground to reduce, saving interior space and concent requirements from the users. The design of smoke control are main contenders of highrise building. According to the 《 criterion on the fireproofing in highrise building for daily usage 》 , It chooses positive pressure ventilation smoke controlling and natural discharge air sestem, set up a delivery outlet every twotier in stair well and every onetier in front floor. The blower is installed in the roof. Underground construction and the positive pressure ventilation use the same furnace through the window for the smoke controlling. Key words: heating。 household heat metering。 smoke controlling 內(nèi)蒙古科技大學(xué)畢業(yè)設(shè)計(jì) 說(shuō)明書(shū) III 目 錄 摘 要 .........................................................................................................................................
