  随着(zhe)国(guo)家经济(ji)的(de)飞(fei)速发(fa)展,楼宇自动(dong)化水平也(ye)越来越高,中央(yang)空调也(ye)逐渐(jian)进入到人们(men)(men)的(de)生活中。它在人们(men)(men)现代生活中发(fa)挥着(zhe)巨大(da)(da)的(de)作(zuo)用,但在为人们(men)(men)营(ying)造舒(shu)适(shi)生活和工作(zuo)环境的(de)同(tong)时也(ye)带来了(le)巨大(da)(da)的(de)能(neng)(neng)(neng)(neng)源(yuan)(yuan)消(xiao)耗(hao)问题。从各国(guo)调查数(shu)据可以(yi)看出,在发(fa)达国(guo)家,建(jian)筑能(neng)(neng)(neng)(neng)耗(hao)约(yue)占(zhan)总能(neng)(neng)(neng)(neng)耗(hao)的(de)30%~40%,我国(guo)建(jian)筑能(neng)(neng)(neng)(neng)耗(hao)占(zhan)世界总能(neng)(neng)(neng)(neng)耗(hao)的(de)12%左右。而中央(yang)空调能(neng)(neng)(neng)(neng)耗(hao)在建(jian)筑能(neng)(neng)(neng)(neng)耗(hao)中占(zhan)了(le)很大(da)(da)比重,一般中央(yang)空调能(neng)(neng)(neng)(neng)耗(hao)占(zhan)整个建(jian)筑能(neng)(neng)(neng)(neng)耗(hao)的(de)50%以(yi)上。所(suo)以(yi)如何(he)在满足人们(men)(men)最大(da)(da)舒(shu)适(shi)度的(de)前提下又能(neng)(neng)(neng)(neng)最大(da)(da)限度的(de)节约(yue)能(neng)(neng)(neng)(neng)源(yuan)(yuan)成(cheng)(cheng)为各界逐渐(jian)关(guan)注的(de)焦点之一。如何(he)最大(da)(da)限度的(de)节约(yue)能(neng)(neng)(neng)(neng)源(yuan)(yuan)已成(cheng)(cheng)为智能(neng)(neng)(neng)(neng)建(jian)筑、楼宇自动(dong)化领域的(de)一个重要课题。而

  在整(zheng)个中央空(kong)调(diao)(diao)的(de)(de)(de)能(neng)(neng)耗(hao)(hao)中,制(zhi)(zhi)(zhi)冷(leng)(leng)系统(tong)(tong)的(de)(de)(de)能(neng)(neng)耗(hao)(hao)又占据了整(zheng)个中央空(kong)调(diao)(diao)系统(tong)(tong)的(de)(de)(de)大(da)部分。中央空(kong)调(diao)(diao)制(zhi)(zhi)(zhi)冷(leng)(leng)系统(tong)(tong)的(de)(de)(de)节能(neng)(neng)不仅跟用户(hu)的(de)(de)(de)经(jing)济(ji)利益密(mi)切相关,还影响着我国国民(min)经(jing)济(ji)的(de)(de)(de)可持续(xu)发展。中央空(kong)调(diao)(diao)制(zhi)(zhi)(zhi)冷(leng)(leng)系统(tong)(tong)是(shi)一个典型的(de)(de)(de)非线性(xing)、大(da)滞(zhi)后、时变性(xing)、强耦合、多干扰的(de)(de)(de)系统(tong)(tong),节能(neng)(neng)就意味着在能(neng)(neng)源的(de)(de)(de)消耗(hao)(hao)和(he)合理的(de)(de)(de)利用之间找到(dao)(dao)平衡点,空(kong)调(diao)(diao)集中化、协调(diao)(diao)化控(kong)制(zhi)(zhi)(zhi)就是(shi)要采用先进的(de)(de)(de)控(kong)制(zhi)(zhi)(zhi)策略和(he)设备对其进行(xing)准(zhun)确的(de)(de)(de)控(kong)制(zhi)(zhi)(zhi)和(he)调(diao)(diao)整(zheng),加(jia)强对中央空(kong)调(diao)(diao)制(zhi)(zhi)(zhi)冷(leng)(leng)系统(tong)(tong)设备的(de)(de)(de)运行(xing)控(kong)制(zhi)(zhi)(zhi)能(neng)(neng)力(li),优化运行(xing)过程,既能(neng)(neng)满(man)足(zu)社会(hui)(hui)需求,又可达到(dao)(dao)节能(neng)(neng)减排的(de)(de)(de)目的(de)(de)(de),具有巨大(da)的(de)(de)(de)经(jing)济(ji)和(he)社会(hui)(hui)效(xiao)益。

  随着计算机(ji)、通信等技(ji)术(shu)(shu)的(de)快速(su)发(fa)展,使得(de)通过(guo)提高(gao)自动(dong)(dong)化控(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)制水平降低能源(yuan)消(xiao)耗(hao)成为可能。从上世纪70年代后期开(kai)始,计算机(ji)技(ji)术(shu)(shu)逐渐(jian)进入到(dao)工业控(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)制领域,随着理(li)论(lun)在实(shi)践中(zhong)逐渐(jian)得(de)到(dao)验证,研究人员发(fa)现以前的(de)控(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)制方(fang)式(shi)(shi)越(yue)来(lai)越(yue)达不(bu)(bu)到(dao)大型工业控(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)制的(de)要求。在这种情况下,研究人员开(kai)始探索新的(de)控(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)制方(fang)式(shi)(shi),尤其(qi)是对分(fen)级分(fen)布式(shi)(shi)控(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)制方(fang)法做(zuo)了成功的(de)尝(chang)试,对现场设备进行集(ji)(ji)中(zhong)管理(li)、分(fen)散控(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)制,并且(qie)更容易实(shi)现人机(ji)数(shu)据(ju)交流(liu)和控(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)制,这种控(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)制方(fang)式(shi)(shi)被称(cheng)为集(ji)(ji)散控(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)制系统。对于(yu)中(zhong)央(yang)空调(diao)(diao)这个复(fu)杂的(de)系统,基于(yu)集(ji)(ji)散控(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)制系统高(gao)可靠(kao)性、方(fang)便(bian)操作、便(bian)于(yu)管理(li)、配置灵活、组态方(fang)便(bian)的(de)优势,对中(zhong)央(yang)空调(diao)(diao)的(de)控(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)制来(lai)说(shuo)无疑是很好的(de)选择,不(bu)(bu)仅(jin)可方(fang)便(bian)的(de)对中(zhong)央(yang)空调(diao)(diao)机(ji)组实(shi)现自动(dong)(dong)化控(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)制,还可实(shi)现过(guo)程优化控(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)制,进而(er)实(shi)现整个中(zhong)央(yang)空调(diao)(diao)能耗(hao)的(de)节约。
