　　大通回族土(tu)族自治縣湟中縣制冷設備蒸發溫(wen)(wen)度(du)偏(pian)低的原因很多(duo)，導致蒸發溫(wen)(wen)度(du)偏(pian)低的機(ji)理就(jiu)是蒸發器內的冷媒少或者蒸發器換熱不好，列舉如下：

　　1、膨脹閥開(kai)度小了

　　2、制冷(leng)系統(tong)缺(que)少冷(leng)媒

　　3、毛細管或者膨脹(zhang)閥堵了

選擇冷(leng)水(shui)(shui)機(ji)的(de)(de)(de)(de)(de)具體方(fang)法：工業冷(leng)水(shui)(shui)機(ji)組(zu)的(de)(de)(de)(de)(de)主要用途非常廣泛(fan)。關(guan)鍵是(shi)其(qi)效果和(he)實踐(jian)效果都(dou)很好。自然類型(xing)(xing)標(biao)準有(you)多種類型(xing)(xing)。如(ru)果想要獲得更(geng)強(qiang)的(de)(de)(de)(de)(de)使用感，建議群眾需(xu)(xu)要選擇合適的(de)(de)(de)(de)(de)類型(xing)(xing)標(biao)準，這(zhe)樣(yang)才能獲得更(geng)強(qiang)的(de)(de)(de)(de)(de)使用和(he)實踐(jian)效果，充(chong)分發揮其(qi)所需(xu)(xu)的(de)(de)(de)(de)(de)優勢。首先，建議廣大群眾要掌握(wo)不同標(biao)準類型(xing)(xing)的(de)(de)(de)(de)(de)冷(leng)水(shui)(shui)機(ji)組(zu)。
