毛細(xì)銅管換熱器**1大的優(yōu)點(diǎn)在于能降低換熱器的成本。從現(xiàn)有的資料來(lái)看，在達(dá)到相同性能的情況下，小管徑銅管換熱器相對(duì)于現(xiàn)有普遍的7mm及以上管徑的換熱器，能夠降低20%左右的成本。 </p> <p> 此外，在相同的系統(tǒng)中，采用小管徑銅管換熱器替代原有較大管徑的換熱器，能夠減少制冷劑的充注量，南京超毛細(xì)毛細(xì)紫銅管制造商。因?yàn)橄啾仍休^大管徑的換熱器，小管徑銅管換熱器的管內(nèi)體積要小很多，而采用強(qiáng)化內(nèi)螺紋的小管徑銅管系統(tǒng)效率也更高，南京超毛細(xì)毛細(xì)紫銅管制造商，所以能有效減少制冷劑的充注量。從資料來(lái)看，南京超毛細(xì)毛細(xì)紫銅管制造商，采用小管徑銅管系統(tǒng)后，制冷劑充注量明顯減少，減少量高達(dá)30%左右，對(duì)環(huán)境保護(hù)有益。

毛細(xì)管的內(nèi)徑和長(zhǎng)度必須經(jīng)選擇，但毛細(xì)管的理論計(jì)算比較復(fù)雜，計(jì)算結(jié)構(gòu)誤差也很大，所以一般均在選定內(nèi)徑之后，再來(lái)決定長(zhǎng)度，在規(guī)定的條件下根據(jù)試驗(yàn)結(jié)果來(lái)決定毛細(xì)管尺寸。 </p> <p> 1.氮?dú)鉁y(cè)定法和液體測(cè)量法：測(cè)量方法是在毛細(xì)管連接在入口壓力為表壓980KPa的容器上，環(huán)境溫度保持不變，測(cè)量毛細(xì)管每分鐘的液體流量值。 </p> <p> 2.在制冷系統(tǒng)上直接測(cè)定毛細(xì)管流量：在制冷系統(tǒng)排氣管上連接一個(gè)壓力計(jì)。吸氣口與表壓力為零的干燥空氣或氮?dú)庠聪嘟?。開(kāi)啟壓縮機(jī)后，制冷系統(tǒng)壓力（電冰箱）**1好達(dá)到1200--1300KPa（蒸發(fā)溫度為-15℃至-18℃），如果希望改變蒸發(fā)器壓力，只需要加長(zhǎng)或減短毛細(xì)管的長(zhǎng)度就可以實(shí)現(xiàn)了。這種方法操作簡(jiǎn)單，精度不高，可在維修時(shí)使用。 </p> <p> 3.空調(diào)機(jī)和冷飲機(jī)一類的制冷系統(tǒng)一般使用“空調(diào)工況”，毛細(xì)管較粗，阻力小，用此方法測(cè)定毛細(xì)管的空氣流量值，表壓力可達(dá)到540--590KPa。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px;
