</p> <p> <p> 隨毛細(xì)管的增長，制冷量的**1大值向右偏移，造成這種現(xiàn)象的原因是隨毛細(xì)管的增長，阻力增加，冷凝器內(nèi)集液增多，壓力提高，蒸發(fā)器內(nèi)1供液減少，壓力下降，單位質(zhì)量流量下降，蒸汽器換熱面積利用不充分，灌注量增加，可使蒸發(fā)器內(nèi)工質(zhì)增加，改善其換熱條件，使制冷量增大，所以，毛細(xì)管加長后，冷媒灌注量也要相應(yīng)增加，這樣才會使制冷量達(dá)到**1大。 </p> <p> 同樣，對應(yīng)一定長度的毛細(xì)管，存在一**1佳灌注量使EER值**1大，對于不同長度的毛細(xì)管，其**1佳灌注量對應(yīng)的EER也存在一個(gè)**1大值。制冷量、EER出現(xiàn)**1大值時(shí)的毛細(xì)管長度與灌注量不一定相同，因此必須確定優(yōu)化目標(biāo)，達(dá)到系統(tǒng)**1優(yōu)。
