化工(gong)防爆低(di)溫(wen)制(zhi)(zhi)冷(leng)(leng)(leng)機(ji)組(zu)(zu)廣泛(fan)應用于石化、醫(yi)療、制(zhi)(zhi)藥(yao)、生化、凍干等行業。化工(gong)防爆低(di)溫(wen)制(zhi)(zhi)冷(leng)(leng)(leng)機(ji)組(zu)(zu)是由(you)制(zhi)(zhi)冷(leng)(leng)(leng)壓縮機(ji)、冷(leng)(leng)(leng)凝器、蒸發器和節(jie)流閥四(si)個基本部(bu)件組(zu)(zu)成，它們(men)之間用管路依次連接，形(xing)成一個密閉(bi)的(de)系統(tong)，制(zhi)(zhi)冷(leng)(leng)(leng)劑在(zai)系統(tong)中(zhong)不(bu)斷地循環流動，與外(wai)界進行熱量交換。

　　化(hua)工防爆低溫制(zhi)冷(leng)(leng)機組液體(ti)制(zhi)冷(leng)(leng)劑在(zai)蒸(zheng)發器中吸(xi)收(shou)被(bei)冷(leng)(leng)卻的物(wu)體(ti)熱量(liang)之后，汽(qi)(qi)化(hua)成低溫低壓(ya)(ya)(ya)的蒸(zheng)汽(qi)(qi)、被(bei)壓(ya)(ya)(ya)縮機吸(xi)入(ru)、壓(ya)(ya)(ya)縮成高壓(ya)(ya)(ya)高溫的蒸(zheng)汽(qi)(qi)后排入(ru)冷(leng)(leng)凝(ning)器、在(zai)冷(leng)(leng)凝(ning)器中向冷(leng)(leng)卻介質放熱，冷(leng)(leng)凝(ning)為(wei)(wei)高壓(ya)(ya)(ya)液體(ti)、經(jing)節(jie)流(liu)閥節(jie)流(liu)為(wei)(wei)低壓(ya)(ya)(ya)低溫的制(zhi)冷(leng)(leng)劑、再次進入(ru)蒸(zheng)發器吸(xi)熱汽(qi)(qi)化(hua)，達到循環制(zhi)冷(leng)(leng)的目的。這樣(yang)，制(zhi)冷(leng)(leng)劑在(zai)系(xi)統中經(jing)過蒸(zheng)發、壓(ya)(ya)(ya)縮、冷(leng)(leng)凝(ning)、節(jie)流(liu)四個基本過程完成一個制(zhi)冷(leng)(leng)循環。
