光伏直驅空氣能需要配置多少千瓦光伏板?
建議按照機(ji)(ji)組額(e)定功(gong)率(lv)匹配即(ji)可。 如LSQ20型主(zhu)機(ji)(ji)額(e)定功(gong)率(lv)為5400w,按照每塊(kuai)光(guang)伏(fu)(fu)板(ban)550w計(ji)算,需(xu)要配置(zhi)10塊(kuai),合計(ji)5500w。在光(guang)照較(jiao)好時(shi),即(ji)可滿足主(zhu)機(ji)(ji)耗能需(xu)求(qiu)。即(ji)使光(guang)伏(fu)(fu)板(ban)配置(zhi)較(jiao)少時(shi),也不(bu)影響主(zhu)機(ji)(ji)正(zheng)常啟動,電網會自動進行補(bu)償。

光伏直驅空氣能對光伏板有何要求?
對于光(guang)(guang)伏(fu)(fu)板(ban)(ban)(ban)的廠(chang)家(jia)或者品牌沒有任何強制要求。 只需要光(guang)(guang)伏(fu)(fu)板(ban)(ban)(ban)組串(chuan)(chuan)電(dian)(dian)(dian)壓(ya)滿足(zu)主(zhu)機(ji)(ji)需求即(ji)(ji)可(ke),單相(xiang)220V機(ji)(ji)型,光(guang)(guang)伏(fu)(fu)組串(chuan)(chuan)電(dian)(dian)(dian)壓(ya)應在200V-350V之間(jian),按照每塊板(ban)(ban)(ban)電(dian)(dian)(dian)壓(ya)45V計(ji)算,最多串(chuan)(chuan)聯(lian)7塊光(guang)(guang)伏(fu)(fu)板(ban)(ban)(ban)。三相(xiang)380V機(ji)(ji)型,光(guang)(guang)伏(fu)(fu)組串(chuan)(chuan)電(dian)(dian)(dian)壓(ya)應在300V-450V之間(jian),按照每塊板(ban)(ban)(ban)電(dian)(dian)(dian)壓(ya)45V計(ji)算,最多串(chuan)(chuan)聯(lian)10塊光(guang)(guang)伏(fu)(fu)板(ban)(ban)(ban)。 多個組串(chuan)(chuan)之間(jian)采用并(bing)聯(lian)方式給(gei)主(zhu)機(ji)(ji)供(gong)電(dian)(dian)(dian)即(ji)(ji)可(ke),組串(chuan)(chuan)間(jian)應保證電(dian)(dian)(dian)壓(ya)相(xiang)等(deng)。盡量采用高電(dian)(dian)(dian)壓(ya)組串(chuan)(chuan),以保證在弱光(guang)(guang)條(tiao)件下,光(guang)(guang)伏(fu)(fu)板(ban)(ban)(ban)電(dian)(dian)(dian)壓(ya)偏(pian)低(di)時,仍能保證最低(di)可(ke)利用電(dian)(dian)(dian)壓(ya)。

光伏發電突然斷電對光伏直驅空氣能有什么影響?
沒有(you)影(ying)響! 程序(xu)會(hui)瞬(shun)間增大電(dian)(dian)網輸入功率,由電(dian)(dian)網補(bu)償(chang)供(gong)電(dian)(dian),滿足壓(ya)縮機持(chi)續穩定運(yun)(yun)行,不受光伏(fu)板(ban)斷電(dian)(dian)影(ying)響,此時就相當于一臺普通的空氣能(neng)。待(dai)光伏(fu)板(ban)重新(xin)正常供(gong)電(dian)(dian)后,主板(ban)經過約10s的運(yun)(yun)算,啟動轉(zhuan)入光伏(fu)供(gong)電(dian)(dian)為主的模式,逐(zhu)步降低電(dian)(dian)網功率,此后電(dian)(dian)網只起到補(bu)償(chang)作用。

光伏直驅空氣能可以完全脫離電網運行嗎?
不可以! 原因有(you)2點(dian): 第一點(dian)、光(guang)(guang)伏(fu)(fu)(fu)直驅(qu)空氣(qi)能(neng)的主(zhu)板和水泵均是使(shi)(shi)用的交流電(dian)(dian)(dian),無(wu)法使(shi)(shi)用光(guang)(guang)伏(fu)(fu)(fu)的直流電(dian)(dian)(dian)直接(jie)供(gong)(gong)電(dian)(dian)(dian),電(dian)(dian)(dian)源需要有(you)市電(dian)(dian)(dian)提(ti)(ti)供(gong)(gong),也就是即使(shi)(shi)在光(guang)(guang)伏(fu)(fu)(fu)發(fa)電(dian)(dian)(dian)量足(zu)夠的情況(kuang)下(xia),光(guang)(guang)伏(fu)(fu)(fu)直驅(qu)空氣(qi)能(neng)還(huan)(huan)需要電(dian)(dian)(dian)網(wang)提(ti)(ti)供(gong)(gong)大約(yue)4w的功率(lv)給主(zhu)板供(gong)(gong)電(dian)(dian)(dian),另外還(huan)(huan)有(you)水泵的耗電(dian)(dian)(dian)量。 第二點(dian)、光(guang)(guang)伏(fu)(fu)(fu)發(fa)電(dian)(dian)(dian)本身是不穩定的,受(shou)天氣(qi)等影響波動較(jiao)大、較(jiao)頻繁,需要穩定的電(dian)(dian)(dian)網(wang)提(ti)(ti)供(gong)(gong)實時(shi)補償(chang)。比如光(guang)(guang)伏(fu)(fu)(fu)正常發(fa)電(dian)(dian)(dian)量5kw正好滿足(zu)壓縮機(ji)運(yun)轉,忽然一朵白云遮住太陽,發(fa)電(dian)(dian)(dian)量瞬間(jian)降至4kw,這時(shi)候就需要電(dian)(dian)(dian)網(wang)補償(chang)1kw,以保證壓縮機(ji)平穩運(yun)轉。綜上(shang),光(guang)(guang)伏(fu)(fu)(fu)直驅(qu)空氣(qi)能(neng)無(wu)法完全脫(tuo)離…

根據入戶(hu)調(diao)查取得的(de)(de)(de)客戶(hu)反饋,部分家(jia)庭存在由于房(fang)間(jian)(jian)大、保溫(wen)差,在冬(dong)季(ji)較冷的(de)(de)(de)一段時間(jian)(jian)內,地源熱風機配(pei)置的(de)(de)(de)壓(ya)縮機較小,房(fang)間(jian)(jian)溫(wen)度很(hen)難達到滿意的(de)(de)(de)情況(kuang)。 另(ling)外,用(yong)戶(hu)反饋熱風采暖舒(shu)(shu)適(shi)度較差,空氣(qi)干熱,但(dan)是被子什么的(de)(de)(de)還都(dou)是冷的(de)(de)(de),舒(shu)(shu)適(shi)度較地暖差,已經有很(hen)多用(yong)戶(hu)自行改造了空氣(qi)能+地暖的(de)(de)(de)采暖方式。

熱泵熱風機與空調有什么區別?
相信用戶認(ren)為空(kong)(kong)氣(qi)能熱(re)泵(beng)熱(re)風(feng)機(ji)(ji)和(he)空(kong)(kong)調是(shi)(shi)一(yi)(yi)種(zhong)產(chan)品,都(dou)是(shi)(shi)一(yi)(yi)個室外機(ji)(ji)帶一(yi)(yi)個室內機(ji)(ji),而且都(dou)能制(zhi)(zhi)熱(re)制(zhi)(zhi)冷。 熱(re)泵(beng)熱(re)風(feng)機(ji)(ji)是(shi)(shi)空(kong)(kong)調的(de)升級(ji)版本(ben),采用了噴氣(qi)增焓式壓縮機(ji)(ji),配套雙(shuang)電子膨脹閥(fa)、閃(shan)蒸罐,使(shi)熱(re)泵(beng)熱(re)風(feng)機(ji)(ji)不僅(jin)能在-15℃,甚至是(shi)(shi)-25℃的(de)低(di)溫(wen)環境里(li)工作,而且非常節能,在-15℃的(de)低(di)溫(wen)環境下時,制(zhi)(zhi)熱(re)效率依舊能達到2.2以上(shang)。 對(dui)比家(jia)用空(kong)(kong)調在-5℃時啟動(dong)十(shi)分困(kun)難,運行時也會產(chan)生能效衰減,溫(wen)度再低(di)就需要使(shi)用電輔(fu)助加熱(re),難以滿足北(bei)方家(jia)庭(ting)供暖需求。 兩者在送風(feng)方式上(shang)也有區別(bie):空(kong)(kong)調一(yi)(yi)般是(shi)(shi)安裝在房間頂部,送風(feng)時風(feng)從上(shang)部吹出。夏天…

大型商業項目上變頻機組有優勢嗎?
商用變頻(pin)(pin)機(ji)組(zu)(zu)(zu)對比傳(chuan)統定(ding)頻(pin)(pin)機(ji)組(zu)(zu)(zu)具有以下2個方面的優(you)點: 1.定(ding)頻(pin)(pin)機(ji)組(zu)(zu)(zu)在(zai)(zai)較低負荷時只有啟動和停止兩種(zhong)工作狀(zhuang)態,變頻(pin)(pin)機(ji)組(zu)(zu)(zu)低頻(pin)(pin)恒溫(wen)運(yun)轉可(ke)(ke)有效延緩結霜速度,減少除(chu)霜次數可(ke)(ke)達(da)70%以上。 2.變頻(pin)(pin)機(ji)組(zu)(zu)(zu)在(zai)(zai)較高(gao)負荷時,高(gao)頻(pin)(pin)運(yun)轉,提(ti)升(sheng)壓(ya)縮(suo)機(ji)運(yun)行壓(ya)差,強勁吸熱(re)、高(gao)效換熱(re),能效可(ke)(ke)比定(ding)頻(pin)(pin)機(ji)組(zu)(zu)(zu)提(ti)升(sheng)15%左右。 哈思最早在(zai)(zai)2019年已經完成了(le)商用變頻(pin)(pin)機(ji)組(zu)(zu)(zu)的技術儲備,單機(ji)額定(ding)制(zhi)熱(re)量(環境溫(wen)度7℃)可(ke)(ke)達(da)150kw。并逐(zhu)步(bu)在(zai)(zai)北方區域(yu)推廣應(ying)用,取(qu)得(de)了(le)不錯的運(yun)行數據。

單相變頻和三相變頻性能有差異嗎?
傳統人們認知的(de)(de)380V電(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)(ji)比(bi)220V電(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)(ji)動(dong)(dong)(dong)力足、省電(dian)(dian),準確點說是三(san)相(xiang)電(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)(ji)和單(dan)(dan)相(xiang)電(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)(ji)的(de)(de)對比(bi),都是基于鼠籠(long)電(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)(ji)模型得出(chu)的(de)(de),電(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)(ji)的(de)(de)效(xiao)率(lv)(lv)=輸出(chu)功率(lv)(lv)÷輸入(ru)功率(lv)(lv)×100%,一(yi)(yi)般三(san)相(xiang)電(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)(ji)效(xiao)率(lv)(lv)在(zai)0.9左右(you),而單(dan)(dan)相(xiang)電(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)(ji)的(de)(de)效(xiao)率(lv)(lv)在(zai)0.75左右(you),三(san)相(xiang)電(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)(ji)的(de)(de)總效(xiao)率(lv)(lv)會(hui)高一(yi)(yi)點,所以(yi)三(san)相(xiang)電(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)(ji)較省電(dian)(dian)。所謂(wei)的(de)(de)動(dong)(dong)(dong)力足是說三(san)相(xiang)電(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)(ji)啟動(dong)(dong)(dong)力矩大。 直(zhi)流(liu)變頻空氣能(neng)使用的(de)(de)是直(zhi)流(liu)無刷電(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)(ji),不存在(zai)上述區(qu)別。一(yi)(yi)般情況下,同型號(hao)的(de)(de)機(ji)(ji)(ji)(ji)(ji)(ji)(ji)組,220V和380V機(ji)(ji)(ji)(ji)(ji)(ji)(ji)組壓(ya)縮機(ji)(ji)(ji)(ji)(ji)(ji)(ji)是相(xiang)同的(de)(de),其他(ta)配置相(xiang)同、能(neng)力相(xiang)同、效(xiao)率(lv)(lv)相(xiang)同。唯一(yi)(yi)的(de)(de)區(qu)別就是變頻器將220V轉化為壓(ya)縮機(ji)(ji)(ji)(ji)(ji)(ji)(ji)使…
