制冷系统中蓄冷技术的研究应用

武汉工程大学本科毕业（设计）论文I摘要随着国民经济的日益发展，国民的生活条件也日益改善。空调也已经走进了千家万户。空调的广泛使用大大提高了国民的生活水平，但是也引发了一系列的能源问题。众所周知，空调的使用时间一般都是在冷负荷较大的时间段，且空调的耗电量大，因此造成了电网系统负荷不均匀的局面。具体来说，就是在白天用电高峰期时电网电力不足，造成部分地区拉闸限电；而在晚上处于用电低谷期时，电网的电力过剩，造成了大量的能源浪费。在这种情况下，蓄冷技术应运而生。顾名思义，蓄冷技术就是蓄存冷量的技术。具体来说，就是利用用电低谷期的电量制取冷量储存在某些物质中，在用电高峰期时取出这些冷量以满足空调负荷。因此它使冷量的生产和使用在时间上相互分离，大大降低了电网负担，减少了能量的浪费，也为用户创造了可观的经济效益。本文阐述了蓄冷技术的原理、特点以及分类等，介绍了当前蓄冷技术的发展现状，分析了蓄冷技术的发展前景以及未来的发展方向。并为一栋办公楼设计了一套简单的蓄冷系统。关键词：蓄冷技术；空调系统；节能技术武汉工程大学本科毕业（设计）论文IIAbstractWiththedevelopmentofthenationaleconomy,people'slivingconditionshaveimprovedalot.Airconditioninghasalsoenteredpeople’shomes.Thewidespreaduseofairconditionershasgreatlyimprovedthelivingstandardsofnationals,butinotherside,ithasalsocausedaseriesofenergyproblems.Asweknow,peopleusuallyuseairconditioningwhentheyfeelhot.Andthepowerconsumptionofairconditioningisveryhigh.Soitcausetheloadofelectricnetworkout-off-balance.Specificallyspeaking,atdaytime,theelectricityislack;atnight,theelectricityissurplus.Inthissituation,thecoldstoragetechnologyhasappeared.Asthenamesuggests,thecoldstoragetechnologyisatechnologythatstorecold.Specificallyspeaking,Istheuseofelectricityinelectricityproductionofcoldenergyisstoredincertainsubstances,takesthoseinpeakcoolingcapacitytomeetthecoolingload.Soitmakesthecoolingcapacityoftheproductionanduseofseparatedintime,greatlyreducetheburdenonthenetwork,reducingthewasteofenergy,andbringsaboutconsiderableeconomicbenefitsfortheuser.Thisarticlefocusesontheprinciples,characteristicsandclassificationofcoldstoragetechnology,describesthecurrentstatusofstoragetechnology,analysisofcoolstoragetechnologydevelopmentprospectsanddevelopmentdirectioninthefuture.Andanofficebuildingdesignofasimplestoragesystem.Keywords:coldstoragetechnology;airconditioning;energysavingtechnology.武汉工程大学本科毕业（设计）论文III目录摘要............................................................................................................................................IAbstract........................................................................................................................................II第一章文献综述...........................................................................................................................11.1蓄冷技术在我国发展的社会背景.......................................................................................................11.1.1当前我国所面临的能源问题....................................................................................................11.1.2蓄冷技术在当前能源形势下的前景........................................................................................11.1.3蓄冷技术的意义........................................................................................................................21.2蓄冷技术简介.......................................................................................................................................21.2.1蓄冷技术的历史........................................................................................................................21.2.2什么是蓄冷技术........................................................................................................................21.2.3蓄冷技术的特点........................................................................................................................41.2.4蓄冷系统中的蓄冷介质（蓄冷剂）........................................................................................51.3蓄冷系统分类.......................................................................................................................................71.3.1水蓄冷系统................................................................................................................................71.3.2冰蓄冷系统................................................................................................................................91.3.3共晶盐蓄冷系统......................................................................................................................121.3.4气体水合物蓄冷系统..............................................................................................................131.4蓄冷技术的发展与研究.....................................................................................................................131.4.1蓄冷技术的发展阶段..............................................................................................................131.4.2蓄冷技术的发展特点..............................................................................................................141.4.3我国蓄冷技术发展现状..........................................................................................................141.4.4蓄冷技术发展趋势..................................................................................................................151.5本文工作.............................................................................................................................................15第二章蓄冷技术研究及应用.....................................................................................................162.1项目名称....................................................................
