暖通设计说明书

河南科技大学毕业设计I武汉鸿泰社区医院门诊综合楼空调工程设计摘要武汉鸿泰社区医院门诊楼是包括门诊室、药房、会议室、病房等功能间的高层民用建筑。在大楼的暖通空调系统设计中，对不同的功能间选择了合适的空气处理方式，已达到舒适、节能的目的。夏季根据整个建筑的最大冷负荷和新风冷负荷，确定冷源；冬季根据热负荷和新风热负荷选择热源。通过计算冷、热负荷，得出该建筑物的冷热指标分别为63.3W/m2、34W/m2。对于人员少、负荷小的房间选择除湿能力小、灵活的风机盘管加新风系统；人员多、对温、湿度要求严格的空间采用一次回风全空气系统。通过送风参数和新风负荷的计算，选择无锡申达空调设备有限公司的FP系列风机盘管，ZKD系列、ZKDB系列空气处理机组。空调水系统的竖直采用同程式，水平采用异程式。选用了两台LSBLG494螺杆式冷水机组作为冷源；两台CLSS0.35-95/70-(Q)常压燃气锅炉提供热水，并选则两台BR12板式换热器换热得到空调热水。画出草图进行风、水管的水力计算，冷凝水就近排放到卫生间。然后选择分、集水器和两台型号为LBCM-LN-100的冷却塔，选出循环水泵、冷却水泵等各辅助设备，进行保温防腐设计。关键词：冷、热负荷，风机盘管加新风系统，全空气一次回风系统，水系统，冷热源河南科技大学毕业设计IIWUHANHONTAICOMMUNITYHOSPITALOUTPATIENTBUILDINGHVACDESIGNABSTRACTWuhanhongtaicommunityhospitaloutpatientbuilding,afunctionofhighcivilbuildingsincludepatientrooms,pharmacy,conferencerooms,ward,etc.Inthebuilding'sHVACsystemdesign,accordingtodifferentfunctionroomschooseproperairprocessmethod,tocomfortableandenergy-saving.Accordingtothebuilding'sbiggestsummercoolingloadandaircoolingload,ensurecoldsource;Accordingtotheheatloadandfreshwinterheatloadselectheatsource.Throughcalculatingthecoldandheatload,itisconcludedthatthebuilding’scoldandheatindex,63.3W/m2and34W/m2.Forresearchers,roomswithlesspeopleandloadchoosesmalldehumidifyingcapacityandflexibleprimaryairfancoilsystem;iftemperatureandhumidityofthepaceisstrict,chooseallaironcereturuairsystem.Throughthesupplyairparametersandthenew-windloadcalculation,choosetheairconditioningequipmentofWuxiCo,LTDseriesFPseriesfancoil,ZKDseriesandZKDBseriesairhandlingunitsrespectively.Watersystemofairconditioning,theverticaldirectionwiththesameprocesse,eachlayeristhedifferentprocesse.ChoosethetwoLSBLG494screwwaterchillersascoldsource;TwoCLSS0.35-95/70-(Q)atmosphericgasboilerprovidehotwater,andselectedtwoBR12plateheatexchangerheatgetairconditioninghotwater.Thendrawsketchesofductandconduit’shydraulicalculationandcondensatenearbyemissionsintothetoilet.Choosepoints,catchmentdeviceandtwocoolingtower,themodelisLBCM-LN–100.Selectthecirculatingwaterpumps,thecoolingwaterpumps,andvariousauxiliaryequipment,andthethermalinsulationanticorrosiondesign.河南科技大学毕业设计IIIKEYWORDS:coldandheatload,primaryairandfancoilsystem,allaironcereturnairsystem,watersystem,coldandheatsources河南科技大学毕业设计IV目录前言………………..……………..………………………………......Ⅵ第一章原始资料…………………………………………………........1§1.1能源状况和建筑概况......................................................1§1.2气象资料.......................................................................1§1.3土建资料.......................................................................2§1.4人员和照明....................................................................5§1.5动力资料........................................................................6第二章空调负荷计算......................................................................7§2.1夏季冷负荷计算.............................................................7§2.2冬季热负荷计算...........................................................16§2.3湿负荷计算...................................................................19第三章空调方案的确定................................................................20§3.1空调系统的分类...........................................................20§3.2空调处理系统...............................................................22§3.3空调水系统...................................................................25第四章送风量和送风参数及计算.................................................29§4.1新风量的确定...............................................................29§4.2全空气一次回风送风量、送风参数计算......................30§4.3风机盘管加新风系统送风量、送风参数计算...............34§4.4新风负荷.......................................................................37第五章空气处理设备选型............................................................39§5.1风机盘管的选择...........................................................39§5.2新风机组和全空气处理机组的选择.............................41第六章气流组织...........................................................................44§6.1送风形式及气流分布的相关规定及评价......................44§6.2气流组织形式论证及选择............................................45§6.3气流组织计算...............................................................47第七章冷热源设计.......................................................................52§7.1冷热源的选择...............................................................52河南科技大学毕业设计V§7.2冷热源的确定...............................................................53§7.3冷热源设备型号...........................................................56第八章水力计算...........................................................................59§8.1风管的水力计算...........................................................59§8.2水管的水力计算...........................................................64§8.3冷凝水管的设计...........................................................68第九章机房辅助设备选型............................................................69§9.1机房的布置...................................................................69§9.2机房内附属设备的选择................................................71第十章管道保温、防腐................................................................77结论......................................................................................
