空氣能熱水器顧名思義(yi)就(jiu)是通過(guo)收集空氣中的(de)熱(re)能把冷水(shui)(shui)加熱(re)的(de)熱(re)水(shui)(shui)器(qi)(qi),目前空氣能熱(re)水(shui)(shui)器(qi)(qi)出水(shui)(shui)溫度(du)在55攝氏度(du)范圍內,可滿足洗浴用(yong)水(shui)(shui)要求。
雖說(shuo)空氣能熱水器(qi)好用,可是總(zong)也是存(cun)在(zai)著一些(xie)故障問(wen)題,比(bi)如有些(xie)人遇到空氣能熱水器(qi)的蒸發器(qi)出現結(jie)霜問(wen)題,那么空氣能熱水器(qi)的蒸發器(qi)結(jie)霜是否正常。
空(kong)(kong)氣能(neng)熱(re)水器(qi)的蒸發器(qi)結霜(shuang)(shuang)(shuang)是空(kong)(kong)氣能(neng)工(gong)作工(gong)程中一(yi)個正常(chang)現(xian)象,空(kong)(kong)氣能(neng)熱(re)水器(qi)在冬季結霜(shuang)(shuang)(shuang)是必然的,我們在使用(yong)空(kong)(kong)調(diao)的時候會(hui)發現(xian)外(wai)機(ji)結霜(shuang)(shuang)(shuang)、化霜(shuang)(shuang)(shuang)。同樣熱(re)泵(beng)熱(re)水器(qi)結霜(shuang)(shuang)(shuang)就要除霜(shuang)(shuang)(shuang)、化霜(shuang)(shuang)(shuang)。換熱(re)器(qi)設計系(xi)統的配置,可(ke)以(yi)延緩(huan)結霜(shuang)(shuang)(shuang),降(jiang)低結霜(shuang)(shuang)(shuang)對空(kong)(kong)氣能(neng)熱(re)泵(beng)熱(re)水器(qi)性能(neng)的影(ying)響,可(ke)以(yi)使機(ji)組結霜(shuang)(shuang)(shuang)慢(man)一(yi)點,結霜(shuang)(shuang)(shuang)后對機(ji)組性能(neng)影(ying)響也慢(man)一(yi)些(xie)。
干工況下蒸(zheng)(zheng)(zheng)發(fa)(fa)(fa)器(qi)(qi)不可(ke)能(neng)結霜,零(ling)度(du)工況下是(shi)(shi)可(ke)以結霜的(de)(de)。當蒸(zheng)(zheng)(zheng)發(fa)(fa)(fa)器(qi)(qi)溫(wen)度(du)通(tong)(tong)過蒸(zheng)(zheng)(zheng)發(fa)(fa)(fa)器(qi)(qi)的(de)(de)空(kong)(kong)氣(qi)(qi)降(jiang)到空(kong)(kong)氣(qi)(qi)溫(wen)度(du)時(shi),空(kong)(kong)氣(qi)(qi)中的(de)(de)水分(fen)子(zi)就(jiu)存留(liu)在翅(chi)片(pian)上。而零(ling)度(du)工況對機組換熱(re)是(shi)(shi)有(you)(you)利的(de)(de),具(ju)備顯熱(re)和潛熱(re),干工況交換時(shi)是(shi)(shi)顯熱(re)交換,零(ling)度(du)工況時(shi)就(jiu)是(shi)(shi)潛熱(re)交換了(le),如果零(ling)度(du)工況時(shi)蒸(zheng)(zheng)(zheng)發(fa)(fa)(fa)器(qi)(qi)的(de)(de)表面溫(wen)度(du)低于0℃時(shi)就(jiu)會結霜。蒸(zheng)(zheng)(zheng)發(fa)(fa)(fa)器(qi)(qi)表面開始有(you)(you)微霜時(shi),對換熱(re)器(qi)(qi)的(de)(de)效果是(shi)(shi)有(you)(you)所(suo)提高(gao)的(de)(de),它能(neng)強(qiang)化排熱(re),蒸(zheng)(zheng)(zheng)發(fa)(fa)(fa)器(qi)(qi)表面呈(cheng)現(xian)毛刺(ci)狀,但(dan)是(shi)(shi)隨著(zhu)霜層的(de)(de)加厚(hou),空(kong)(kong)氣(qi)(qi)流通(tong)(tong)的(de)(de)阻力(li)增(zeng)大,勢必阻礙空(kong)(kong)氣(qi)(qi)的(de)(de)流通(tong)(tong),蒸(zheng)(zheng)(zheng)發(fa)(fa)(fa)器(qi)(qi)是(shi)(shi)通(tong)(tong)過空(kong)(kong)氣(qi)(qi)吸熱(re),而空(kong)(kong)氣(qi)(qi)流量減少(shao),吸熱(re)量也同樣減少(shao),這時(shi)機組性能(neng)就(jiu)開始削減。¬這些都與蒸(zheng)(zheng)(zheng)發(fa)(fa)(fa)器(qi)(qi)設(she)計問題、蒸(zheng)(zheng)(zheng)發(fa)(fa)(fa)器(qi)(qi)片(pian)距、蒸(zheng)(zheng)(zheng)發(fa)(fa)(fa)面積、蒸(zheng)(zheng)(zheng)發(fa)(fa)(fa)器(qi)(qi)厚(hou)度(du)、管子(zi)連接有(you)(you)直(zhi)接影響。
