金(jin)光風機盤管的參數(shu)變化對(dui)性(xing)能的影(ying)響
金光空調設備有限公司(si)小(xiao)編今天給大(da)家講一下,風機(ji)(ji)盤(pan)管中的(de)參數(shu)變化(hua)(hua)對性能的(de)影響(xiang)。首先是風機(ji)(ji)盤(pan)管風量(liang)一定,供(gong)水(shui)(shui)(shui)溫(wen)度(du)(du)一定,供(gong)水(shui)(shui)(shui)量(liang)變化(hua)(hua)時候,制(zhi)冷(leng)(leng)量(liang)隨(sui)著供(gong)水(shui)(shui)(shui)量(liang)的(de)變化(hua)(hua)而變化(hua)(hua),根據部(bu)分風機(ji)(ji)盤(pan)管產品性能統計(ji),當(dang)供(gong)水(shui)(shui)(shui)溫(wen)度(du)(du)為7度(du)(du)供(gong)水(shui)(shui)(shui)減少80%時,制(zhi)冷(leng)(leng)量(liang)為原(yuan)來的(de)92%左右(you),說(shuo)明當(dang)供(gong)水(shui)(shui)(shui)量(liang)變化(hua)(hua)時對制(zhi)冷(leng)(leng)量(liang)的(de)影響(xiang)比較緩慢。
再是(shi)風機盤(pan)管供水(shui)(shui)(shui)回水(shui)(shui)(shui)溫(wen)度(du)一定,供水(shui)(shui)(shui)溫(wen)度(du)升高時(shi),制冷量隨著減少。據統計(ji),供水(shui)(shui)(shui)溫(wen)度(du)升高1度(du)時(shi),制冷量減少10%,供水(shui)(shui)(shui)溫(wen)度(du)越高減幅越大(da),除濕能力下降。
風(feng)機(ji)(ji)盤(pan)(pan)管(guan)(guan)在供(gong)水條(tiao)件一定,風(feng)機(ji)(ji)盤(pan)(pan)管(guan)(guan)風(feng)量改(gai)變(bian)(bian)時(shi),制(zhi)冷(leng)(leng)量和(he)空(kong)調處理焓差隨著變(bian)(bian)化。一般是制(zhi)冷(leng)(leng)量減少(shao)(shao),焓差增大(da),單位(wei)制(zhi)冷(leng)(leng)量等級(ji)耗電變(bian)(bian)化不大(da)。其次風(feng)機(ji)(ji)盤(pan)(pan)管(guan)(guan)進出水溫度(du)(du)增大(da)時(shi),水量減少(shao)(shao),換熱(re)(re)盤(pan)(pan)管(guan)(guan)的(de)(de)(de)熱(re)(re)系數(shu)(shu)隨著減少(shao)(shao)。另(ling)外(wai)傳(chuan)熱(re)(re)溫差也發生了變(bian)(bian)化。因此風(feng)機(ji)(ji)盤(pan)(pan)管(guan)(guan)的(de)(de)(de)制(zhi)冷(leng)(leng)量隨著供(gong)水溫度(du)(du)的(de)(de)(de)增大(da)而減少(shao)(shao)。據統計當供(gong)水溫度(du)(du)為(wei)7度(du)(du),供(gong)回水溫度(du)(du)從5度(du)(du)提高到7度(du)(du)時(shi),制(zhi)冷(leng)(leng)量減少(shao)(shao)17%。風(feng)機(ji)(ji)盤(pan)(pan)管(guan)(guan)的(de)(de)(de)參(can)數(shu)(shu)變(bian)(bian)化對性(xing)能(neng)的(de)(de)(de)影響

參數(shu)額定(ding)風量(liang)、出口靜壓、輸入功率、額定(ding)供冷量(liang)、額定(ding)供熱量(liang)、噪聲、水(shui)阻等。對于(yu)雙管制水(shui)系(xi)統(適用于(yu)只(zhi)按(an)(an)季節或(huo)只(zhi)按(an)(an)空(kong)(kong)調區域進行供熱或(huo)供冷轉(zhuan)換(huan)的(de)空(kong)(kong)調系(xi)統)的(de)風機(ji)盤(pan)(pan)管機(ji)組(zu)(zu),只(zhi)配置一組(zu)(zu)盤(pan)(pan)管,冬(dong)夏供熱/ 供冷兼用機(ji)型(xing)。對于(yu)四管制水(shui)系(xi)統(適用于(yu)供熱/ 供冷頻繁轉(zhuan)換(huan)的(de)空(kong)(kong)調系(xi)統) 的(de)風機(ji)盤(pan)(pan)管機(ji)組(zu)(zu),應配置加熱和冷卻兩組(zu)(zu)盤(pan)(pan)管的(de)組(zu)(zu)合式(shi)機(ji)型(xing)。所以(yi)說風機(ji)盤(pan)(pan)管參數(shu)變(bian)化(hua)風機(ji)盤(pan)(pan)管性能(neng)是有一定(ding)的(de)影(ying)響的(de)
