毕业设计(论文)摘要本次设计课题是广东一家沃尔玛超市的中央空调制冷机组控制系统设计,设计目的是为该商场设计合理的中央空调制冷机组控制系统,为商场里的工作人员提供舒适的工作环境。该中央空调系统采用的是水系统,主要有制冷主机、冷却水循环系统、冷冻水循环系统、风机盘管系统和冷却塔系统组成。工作原理是冷冻水泵用来循环冷冻水,冷冻水进入风机盘管,与室内进行热交换,降低室内空气温度,达到制冷目的;冷却水泵用来循环冷却水,冷冻水带走室内热量,通过主机内的冷媒将热量传递给冷却水,冷却水泵将升温后的冷却水压入冷却塔,使之与大气进行热交换,降温后送回主机。设计采用杰控的FameView绘制并设计了中央空调系统的监控系统画面,画面简洁易懂,操作方便,效果逼真,达到了该商场对中央空调系统的要求。关键词:中央空调、制冷主机、冷却泵、冷冻泵、风机盘管。AbstractThisdesigntopicisawal-martstoreinguangdongprovinceofcentralairconditioningrefrigerationunittocontrolsystemdesign,thedesignpurposeisforthestoredesignreasonable,centralairconditioningsystemforshoppingmallsprovidecomfortableworkingenvironmentforstaff.Thecentralairconditioningsystemadoptsthewatersystem,mainlyhasrefrigerationhost,coolingwatercirculationsystem,frozenwatercyclesystem,fancoilsystemandcoolingtowersystem.Frozenwaterpumpworkingprincipleisusedasacycleoffrozenwater,chilledwaterintothefancoil,heattransferwithinterior,reduceindoorairtemperature,toachieverefrigeration;Coolingwaterpumpisusedforcirculatingcoolingwater,chilledwatertakeindoorquantityofheat,throughtherefrigerantwithinthehosttransferheattothecoolingwater,coolingwaterpumpwillheatupthecoolingwaterpressureintothecoolingtowerandheatexchangewiththeatmosphere,backtothehostaftercooling.ControldesignusejiekongFameViewdrawanddesignthemonitoringsystemofcentralairconditioningsystem,appearanceisconciseandeasytounderstand,tolife,hasreachedtherequirementofthemarketofcentralairconditioningsystem.Keywords:thecentralairconditioning,refrigerationhost,coolingpump,frozenpump,fancoilunits.目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc358396831"1绪论PAGEREF_Toc358396831\h1HYPERLINK\l"_Toc358396832"1.1课题背景PAGEREF_Toc358396832\h1HYPERLINK\l"_Toc358396833"1.2商场暖通空调设计的特殊性问题PAGEREF_Toc358396833\h2HYPERLINK\l"_Toc358396834"1.3百货商场类建筑空调系统设计的注重点PAGEREF_Toc358396834\h2HYPERLINK\l"_Toc358396835"1.4百货商场的空调方式PAGEREF_Toc358396835\h3HYPERLINK\l"_Toc358396836"1.5本章小结PAGEREF_Toc358396836\h3HYPERLINK\l"_Toc358
