某税务局办公区空调控制系统设计

某税务局办公区空调控制系统设计摘要随着现代科技的不断发展，智能楼宇系统也在不断发展，而作为现代建筑智能化最重要标志的中央空调控制系统，伴随着现代电子信息技术的发展，在全世界范围内也得到了迅猛的发展，且形成了一套特有的经典理论，这对后世的中央空调控制系统的发展必然有着深远的影响。中央空调控制系统现已成为智能建筑实现智能化空调监控和管理所必需的系统。本设计主要以某税务局办公区空调控制系统为例，首先介绍了中央空调控制系统的发展状况和研究背景，然后详细研究了空调系统和控制系统的基本原理，结合几种具体的空调系统控制框图进行优略分析，进而选择适合本设计的控制方案，结合具体的选型手册进行设备选型，最后对本设计进行了基本的经济性分析。本设计的设计重心放在对风机盘管加新风系统的控制分析和选型上。关键词：智能楼宇中央空调控制风机盘管TheDesignofAirConditioningControlSystemofaTaxBureau’sOfficeAreaABSTRACTWiththedevelopmentofmodernscienceandtechnology，intelligentbuildingsystemisalsoinprogress.Centralair-conditioningcontrolsystemhasbecomethemostimportantsymbolinmodernintelligentbuilding，Withthedevelopmentofmodernelectronicinformationtechnology，Alsogotrapiddevelopmentworldwide，Andformedasetofuniqueclassicaltheory.Thedevelopmentofthissystemofcentralairconditionercontrolonfuturegenerationswillhaveaprofoundimpact.Centralair-conditioningcontrolsystemhasbecomeasystemofintelligentbuildingrequiredtoachievetheintelligentairconditioningmonitoringandmanagement.ThisdesignmainlyintheInlandRevenueDepartmentofficeairconditioningcontrolsystemasanexample.Itfirstintroducesthedevelopmentstatusandresearchbackgroundofcentralair-conditioningcontrolsystem.Thenwestudythebasicprincipleofairconditioningsystemandcontrolsystem.Combinedairconditioningsystemwithseveralcontrolchartsandanalysis.Andthenchoosethecontrolschemeofthedesign.Combinedwiththemanualselectionofspecificequipment。Attheendofthedesignoftheeconomicanalysisofthebasic，Thedesignfocusofthedesignonthecontrolanalysisandselectionoffan-coilunitplusfreshairsystem.KeyWords:IntelligentbuildingCentralair-conditioningControlsystemFancoilsystem目录第一章绪论···········································································································11.1课题研究背景································································································11.2课题研究目的································································································11.3国内外发展状况····························································································21.3.1在单室内机的房间空调器方面······························································21.3.2在多室内机的房间空调器(一机多挂系统)方面······································31.4本文的主要研究内容······················································································4第二章中央空调控制系统方案选择································································62.1中央空调系统································································································62.1.1中央空调系统的一般组成·····································································62.1.2中央空调系统的分类············································································72.1.3中央空调系统的发展状况·····································································72.2中央空调控制系统·························································································82.2.1中央空调控制系统的特点·····································································82.2.2中央空调系统的基本自控原理·····························································122.2.3空调自动化的任务及内容····································································132.2.4空调自控系统的分类···········································································14第三章冷负荷计算··························································································193.1建筑物基本情况概述·····················································································193.2建筑物冷负荷计算························································································19第四章中央空调控制系统方案设计······························································254.1设计原则······································································································254.2方案简介······································································································254.3系统设计需求·······························································································274.3.1设备管理····························································································274.3.2精度要求····························································································274.4控制对象介绍·······························································································284.5新风机组控制系统和风机盘管控制系统·························································304.5.1新风机组控制·····················································································304.5.2风机盘管系统控制···············································································314.6I/O点布置··································································································334.7控制算法简介·······························································································344.7.1送风温度的控制··················································································344.7.2送风湿度的控制··················································································354.8通信协议······································································································35第五章控制系统主
