  在现(xian)代的(de)城市生活(huo)中,医院、学校、商场、办公场所、住宅小区等场所都有电(dian)梯的(de)影子,并(bing)且电(dian)梯数量(liang)越来越多。我国电(dian)梯的(de)生产、安装总量(liang)位居全球的(de)首(shou)位,其中有近1/3的(de)老旧电(dian)梯,节(jie)能型电(dian)梯的(de)应用数量(liang)不足(zu)10%。面对如此(ci)庞大的(de)能源消(xiao)耗,展开节(jie)能审查与监督工作,采取有效的(de)节(jie)能降耗措施具有重要意义(yi)。


  电梯节能技术的应用


  群控技术


  随着(zhe)科技发展,自动化(hua)、信息(xi)化(hua)技术(shu)(shu)在(zai)各领域(yu)中得到(dao)了应用与(yu)推广(guang)。电(dian)(dian)(dian)(dian)梯(ti)在(zai)运行(xing)过程(cheng)中启动、刹车、加速等(deng)都会(hui)产生大(da)量的(de)(de)电(dian)(dian)(dian)(dian)能(neng)(neng)消耗。电(dian)(dian)(dian)(dian)梯(ti)群(qun)控(kong)技术(shu)(shu)能(neng)(neng)够对此展开智(zhi)能(neng)(neng)的(de)(de)控(kong)制(zhi)(zhi)预分配,减少(shao)电(dian)(dian)(dian)(dian)梯(ti)停靠、开启的(de)(de)次数,提高电(dian)(dian)(dian)(dian)梯(ti)运行(xing)效(xiao)率,有规律、有目标的(de)(de)进行(xing)高效(xiao)运行(xing),从(cong)而(er)实现节能(neng)(neng)降耗的(de)(de)效(xiao)果。电(dian)(dian)(dian)(dian)梯(ti)群(qun)控(kong)技术(shu)(shu)主(zhu)要依托于计算(suan)(suan)机控(kong)制(zhi)(zhi)平台,实现对多台电(dian)(dian)(dian)(dian)梯(ti)的(de)(de)集中控(kong)制(zhi)(zhi),通过智(zhi)能(neng)(neng)控(kong)制(zhi)(zhi)算(suan)(suan)法(fa),对楼内电(dian)(dian)(dian)(dian)梯(ti)运行(xing)及使用情(qing)况进行(xing)判断,通过科学的(de)(de)计算(suan)(suan)输出控(kong)制(zhi)(zhi)信号,从(cong)而(er)调整电(dian)(dian)(dian)(dian)梯(ti)的(de)(de)运行(xing)状态(tai)。从(cong)目前来看,电(dian)(dian)(dian)(dian)梯(ti)群(qun)控(kong)智(zhi)能(neng)(neng)算(suan)(suan)法(fa)有模糊控(kong)制(zhi)(zhi)算(suan)(suan)法(fa)、网络神经算(suan)(suan)法(fa)、专家(jia)系统算(suan)(suan)法(fa)等(deng)多种方法(fa),智(zhi)能(neng)(neng)控(kong)制(zhi)(zhi)算(suan)(suan)法(fa)可以结合不同方法(fa)的(de)(de)优势达到(dao)多样化(hua)的(de)(de)控(kong)制(zhi)(zhi)效(xiao)果。


  变频器再生能量回馈技术


  变频器在当代节能领域中受到了广泛应用,比如:空调系统、电力系统等等,采取变频调速的方法控制电梯运行中所产生的机械位能,对这种力量加以利用,降低电能运行过程中所产生的能耗。电梯的运行离不开电力能源,这也是造成能源损耗的一方面,如何才能将这部分的能量转化为再生能量回馈技术是值得研究的一个重点问题。电梯在运行过程中达到指定楼层的时候,速度会逐渐降慢,这就会释放掉一部分的机械能,通过变频器再生能量回馈技术对释放掉的机械能回收利用,可以达到节能降耗的效果。J9九游会AG 所说的变频器再生能量回馈技术就是将机械能转换为一种其他可利用的能源,通过能量存储利用逆变技术将其传输回电网当中,从而实现能量收集与反馈目的。相比于其他节能降耗技术,变频器再生能量回馈技术的应用能够从整体上降低电梯能耗,具有16%-40%不等的效果。电梯的运行速度与使用频率越高,机械能量越多,得到的反馈能量越大。


  永磁同步驱动技术


  这(zhei)种(zhong)技术的(de)(de)应(ying)用主(zhu)要针(zhen)对电(dian)(dian)(dian)(dian)动机(ji)(ji)方(fang)面,从电(dian)(dian)(dian)(dian)动机(ji)(ji)的(de)(de)设计与制造工(gong)艺入手,提高电(dian)(dian)(dian)(dian)梯的(de)(de)节(jie)能(neng)效(xiao)(xiao)果(guo)。永磁(ci)(ci)同步(bu)驱动技术是当前电(dian)(dian)(dian)(dian)梯节(jie)能(neng)的(de)(de)一个主(zhu)要措施。当前很多的(de)(de)老旧(jiu)电(dian)(dian)(dian)(dian)梯采取机(ji)(ji)械传统系(xi)统,永磁(ci)(ci)同步(bu)驱动技术就是在电(dian)(dian)(dian)(dian)动机(ji)(ji)的(de)(de)转(zhuan)子表(biao)面加上(shang)一块永久性(xing)的(de)(de)磁(ci)(ci)铁,这(zhei)样可以使电(dian)(dian)(dian)(dian)动机(ji)(ji)电(dian)(dian)(dian)(dian)源在恒定不变的(de)(de)状(zhuang)态下保(bao)持稳定运行(xing),不仅可以提高电(dian)(dian)(dian)(dian)梯的(de)(de)运行(xing)效(xiao)(xiao)率(lv),还能(neng)节(jie)约电(dian)(dian)(dian)(dian)力能(neng)源。将永磁(ci)(ci)同步(bu)驱动技术应(ying)用于(yu)电(dian)(dian)(dian)(dian)器的(de)(de)曳引机(ji)(ji),具(ju)有噪音低、效(xiao)(xiao)率(lv)高、运行(xing)平(ping)稳的(de)(de)优点,这(zhei)在很大程度上(shang)转(zhuan)变了传统电(dian)(dian)(dian)(dian)梯沉重的(de)(de)减速箱,从而实现电(dian)(dian)(dian)(dian)梯节(jie)能(neng)降耗效(xiao)(xiao)果(guo)。


  老电梯节能改造


  除(chu)了(le)现有电(dian)(dian)(dian)(dian)梯(ti)的(de)(de)(de)(de)(de)(de)节(jie)能(neng)(neng)降耗技(ji)术,对老(lao)电(dian)(dian)(dian)(dian)梯(ti)进(jin)行节(jie)能(neng)(neng)改(gai)造(zao)(zao)也(ye)是降低能(neng)(neng)耗的(de)(de)(de)(de)(de)(de)很大一方(fang)面,由于传统的(de)(de)(de)(de)(de)(de)电(dian)(dian)(dian)(dian)梯(ti)采用交流变级(ji)调速技(ji)术比较多,所(suo)造(zao)(zao)成(cheng)的(de)(de)(de)(de)(de)(de)电(dian)(dian)(dian)(dian)能(neng)(neng)损耗很大,产生(sheng)大量(liang)的(de)(de)(de)(de)(de)(de)电(dian)(dian)(dian)(dian)费。通过对电(dian)(dian)(dian)(dian)梯(ti)控制系统进(jin)行改(gai)造(zao)(zao),采用现代化变频(pin)控制技(ji)术与永磁同(tong)步电(dian)(dian)(dian)(dian)机(ji)的(de)(de)(de)(de)(de)(de)方(fang)法能(neng)(neng)够节(jie)省(sheng)30%-45%的(de)(de)(de)(de)(de)(de)电(dian)(dian)(dian)(dian)量(liang),另外搭配上面J9九游会AG 所(suo)说的(de)(de)(de)(de)(de)(de)能(neng)(neng)量(liang)反馈技(ji)术所(suo)获得(de)到节(jie)电(dian)(dian)(dian)(dian)效果更加可观。从目(mu)前来看,我(wo)国老(lao)旧(jiu)电(dian)(dian)(dian)(dian)梯(ti)数量(liang)不在少数,如(ru)果每台平均节(jie)电(dian)(dian)(dian)(dian)35%,那每年所(suo)节(jie)省(sheng)的(de)(de)(de)(de)(de)(de)用电(dian)(dian)(dian)(dian)量(liang)是非常庞(pang)大的(de)(de)(de)(de)(de)(de),不仅可以减少成(cheng)本费用还(hai)能(neng)(neng)确保电(dian)(dian)(dian)(dian)梯(ti)运(yun)行的(de)(de)(de)(de)(de)(de)安全、稳(wen)定。


  采用绿色节能技术


  面对(dui)日(ri)益(yi)(yi)(yi)紧张的(de)(de)(de)(de)能(neng)(neng)(neng)源(yuan)(yuan)情况(kuang),可(ke)再(zai)生能(neng)(neng)(neng)源(yuan)(yuan)的(de)(de)(de)(de)应(ying)(ying)用(yong)逐渐受(shou)到大家的(de)(de)(de)(de)重(zhong)视。比(bi)如(ru):太阳(yang)(yang)(yang)能(neng)(neng)(neng)、风能(neng)(neng)(neng)、地热能(neng)(neng)(neng)等绿(lv)色(se)能(neng)(neng)(neng)源(yuan)(yuan)的(de)(de)(de)(de)应(ying)(ying)用(yong)水平越(yue)来(lai)越(yue)高,在各领域(yu)的(de)(de)(de)(de)技术(shu)也日(ri)益(yi)(yi)(yi)完善(shan),将绿(lv)色(se)节能(neng)(neng)(neng)技术(shu)应(ying)(ying)用(yong)到电(dian)梯节能(neng)(neng)(neng)降(jiang)耗(hao)中(zhong),具有(you)良(liang)好的(de)(de)(de)(de)生态效益(yi)(yi)(yi)与经济效益(yi)(yi)(yi)。在一些(xie)高层建(jian)筑的(de)(de)(de)(de)顶层安装(zhuang)太阳(yang)(yang)(yang)能(neng)(neng)(neng)收(shou)取(qu)装(zhuang)置,将太阳(yang)(yang)(yang)能(neng)(neng)(neng)转(zhuan)化为(wei)电(dian)能(neng)(neng)(neng)为(wei)电(dian)梯运行(xing)(xing)提供(gong)支持,当白天日(ri)照充足(zu)的(de)(de)(de)(de)时候,太阳(yang)(yang)(yang)能(neng)(neng)(neng)量可(ke)以储(chu)存在相应(ying)(ying)的(de)(de)(de)(de)装(zhuang)置中(zhong),夜间为(wei)电(dian)梯运行(xing)(xing)提供(gong)能(neng)(neng)(neng)量,从而减小对(dui)电(dian)力能(neng)(neng)(neng)源(yuan)(yuan)的(de)(de)(de)(de)消(xiao)耗(hao)


  电(dian)(dian)梯节(jie)(jie)(jie)能(neng)技术的推广(guang)应用(yong)(yong),不但能(neng)节(jie)(jie)(jie)省用(yong)(yong)电(dian)(dian)量(liang),更具有减少碳排量(liang)、节(jie)(jie)(jie)能(neng)环保(bao)的社会深远意义。电(dian)(dian)梯业正朝着高科技绿色产品方(fang)向发(fa)展,安全、高效、环保(bao)将成为未来(lai)电(dian)(dian)梯业的发(fa)展趋势和共同目(mu)标。
