金光風機盤管的參數變化對性能的影響(xiang)

金光空調(diao)設備有限公(gong)司(si)小編今天給大家(jia)講一下，風機盤(pan)管(guan)(guan)中的(de)參數(shu)變(bian)化(hua)對(dui)(dui)性能(neng)的(de)影響(xiang)。首(shou)先是風機盤(pan)管(guan)(guan)風量一定，供水(shui)溫度一定，供水(shui)量變(bian)化(hua)時候，制(zhi)冷(leng)量隨(sui)著供水(shui)量的(de)變(bian)化(hua)而變(bian)化(hua)，根據部分風機盤(pan)管(guan)(guan)產品性能(neng)統計，當供水(shui)溫度為7度供水(shui)減少80%時，制(zhi)冷(leng)量為原(yuan)來(lai)的(de)92%左右，說明當供水(shui)量變(bian)化(hua)時對(dui)(dui)制(zhi)冷(leng)量的(de)影響(xiang)比較(jiao)緩慢。

再是風機盤管供(gong)(gong)水回水溫度(du)一定，供(gong)(gong)水溫度(du)升(sheng)(sheng)高(gao)時(shi)，制(zhi)(zhi)冷量隨著減少。據(ju)統計(ji)，供(gong)(gong)水溫度(du)升(sheng)(sheng)高(gao)1度(du)時(shi)，制(zhi)(zhi)冷量減少10%，供(gong)(gong)水溫度(du)越高(gao)減幅越大，除濕能力下降。

風(feng)機(ji)(ji)(ji)盤(pan)(pan)管(guan)(guan)在供(gong)水(shui)條件一定(ding)，風(feng)機(ji)(ji)(ji)盤(pan)(pan)管(guan)(guan)風(feng)量(liang)(liang)改(gai)變(bian)時(shi)(shi)，制冷(leng)(leng)量(liang)(liang)和(he)空調處理焓差隨(sui)(sui)著變(bian)化(hua)。一般是制冷(leng)(leng)量(liang)(liang)減(jian)少，焓差增大，單位制冷(leng)(leng)量(liang)(liang)等級耗電變(bian)化(hua)不(bu)大。其(qi)次風(feng)機(ji)(ji)(ji)盤(pan)(pan)管(guan)(guan)進出水(shui)溫(wen)度(du)(du)增大時(shi)(shi)，水(shui)量(liang)(liang)減(jian)少，換熱盤(pan)(pan)管(guan)(guan)的熱系數(shu)隨(sui)(sui)著減(jian)少。另外傳熱溫(wen)差也發生了(le)變(bian)化(hua)。因此風(feng)機(ji)(ji)(ji)盤(pan)(pan)管(guan)(guan)的制冷(leng)(leng)量(liang)(liang)隨(sui)(sui)著供(gong)水(shui)溫(wen)度(du)(du)的增大而(er)減(jian)少。據統計當供(gong)水(shui)溫(wen)度(du)(du)為7度(du)(du)，供(gong)回(hui)水(shui)溫(wen)度(du)(du)從5度(du)(du)提高到7度(du)(du)時(shi)(shi)，制冷(leng)(leng)量(liang)(liang)減(jian)少17%。風(feng)機(ji)(ji)(ji)盤(pan)(pan)管(guan)(guan)的參數(shu)變(bian)化(hua)對性(xing)能的影響(xiang)

金光風(feng)(feng)(feng)機(ji)(ji)(ji)盤管(guan)主要由風(feng)(feng)(feng)機(ji)(ji)(ji)，換熱(re)盤管(guan)和機(ji)(ji)(ji)殼(ke)組成，按風(feng)(feng)(feng)機(ji)(ji)(ji)盤管(guan)機(ji)(ji)(ji)外靜壓(ya)可(ke)分為標準型和高靜壓(ya)型，按換熱(re)盤管(guan)排數可(ke)分為兩排和三(san)排，換熱(re)盤管(guan)一般是(shi)采用(yong)銅(tong)管(guan)串鋁(lv)翅片(pian)，銅(tong)管(guan)外徑為10～16mm，翅片(pian)厚度約0.15～0.2mm，間(jian)距2.0～3.0mm，風(feng)(feng)(feng)機(ji)(ji)(ji)一般采用(yong)雙進風(feng)(feng)(feng)前彎形葉片(pian)離心風(feng)(feng)(feng)機(ji)(ji)(ji)，電(dian)(dian)機(ji)(ji)(ji)采用(yong)電(dian)(dian)容式4極單(dan)相電(dian)(dian)機(ji)(ji)(ji)、三(san)檔轉速、機(ji)(ji)(ji)殼(ke)和凝水盤隔(ge)熱(re)。

參數額定風(feng)量(liang)(liang)、出口(kou)靜壓(ya)、輸入(ru)功率、額定供(gong)冷量(liang)(liang)、額定供(gong)熱(re)(re)量(liang)(liang)、噪聲(sheng)、水阻等。對于雙(shuang)管(guan)(guan)制水系(xi)(xi)統(tong)(適用于只(zhi)按季節或(huo)只(zhi)按空調區(qu)域進行(xing)供(gong)熱(re)(re)或(huo)供(gong)冷轉換的(de)(de)空調系(xi)(xi)統(tong))的(de)(de)風(feng)機(ji)(ji)(ji)盤(pan)(pan)管(guan)(guan)機(ji)(ji)(ji)組(zu)，只(zhi)配(pei)置(zhi)一組(zu)盤(pan)(pan)管(guan)(guan)，冬夏供(gong)熱(re)(re)/ 供(gong)冷兼(jian)用機(ji)(ji)(ji)型。對于四管(guan)(guan)制水系(xi)(xi)統(tong)(適用于供(gong)熱(re)(re)/ 供(gong)冷頻繁轉換的(de)(de)空調系(xi)(xi)統(tong)) 的(de)(de)風(feng)機(ji)(ji)(ji)盤(pan)(pan)管(guan)(guan)機(ji)(ji)(ji)組(zu)，應配(pei)置(zhi)加熱(re)(re)和冷卻兩組(zu)盤(pan)(pan)管(guan)(guan)的(de)(de)組(zu)合式(shi)機(ji)(ji)(ji)型。所以說(shuo)風(feng)機(ji)(ji)(ji)盤(pan)(pan)管(guan)(guan)參數變化風(feng)機(ji)(ji)(ji)盤(pan)(pan)管(guan)(guan)性能是有一定的(de)(de)影(ying)響(xiang)的(de)(de)
