冷(leng)(leng)(leng)凝(ning)(ning)(ning)溫(wen)度(du)(du)(du)是指冷(leng)(leng)(leng)凝(ning)(ning)(ning)器(qi)內的(de)(de)氣體(ti)制冷(leng)(leng)(leng)劑在(zai)一(yi)(yi)定壓(ya)(ya)力(li)下凝(ning)(ning)(ning)結成液體(ti)時的(de)(de)溫(wen)度(du)(du)(du)，可(ke)通過(guo)冷(leng)(leng)(leng)凝(ning)(ning)(ning)壓(ya)(ya)力(li)對(dui)應(ying)查(cha)出。水(shui)(shui)冷(leng)(leng)(leng)式冷(leng)(leng)(leng)凝(ning)(ning)(ning)器(qi)的(de)(de)冷(leng)(leng)(leng)凝(ning)(ning)(ning)溫(wen)度(du)(du)(du)取決(jue)于冷(leng)(leng)(leng)卻水(shui)(shui)溫(wen)度(du)(du)(du)和冷(leng)(leng)(leng)卻水(shui)(shui)量(liang)(liang)，通常情況冷(leng)(leng)(leng)凝(ning)(ning)(ning)溫(wen)度(du)(du)(du)比(bi)冷(leng)(leng)(leng)卻水(shui)(shui)出水(shui)(shui)溫(wen)度(du)(du)(du)高(gao)(gao)3～5℃。風冷(leng)(leng)(leng)式冷(leng)(leng)(leng)凝(ning)(ning)(ning)器(qi)的(de)(de)冷(leng)(leng)(leng)凝(ning)(ning)(ning)溫(wen)度(du)(du)(du)一(yi)(yi)般(ban)比(bi)空氣溫(wen)度(du)(du)(du)高(gao)(gao)10～15℃。冷(leng)(leng)(leng)凝(ning)(ning)(ning)溫(wen)度(du)(du)(du)升高(gao)(gao)會使冷(leng)(leng)(leng)凝(ning)(ning)(ning)壓(ya)(ya)力(li)也升高(gao)(gao)，由此(ci)將(jiang)給制冷(leng)(leng)(leng)系(xi)統的(de)(de)運行(xing)帶來一(yi)(yi)系(xi)列(lie)問題(ti)，因此(ci)應(ying)在(zai)制冷(leng)(leng)(leng)設備運轉中控(kong)制冷(leng)(leng)(leng)凝(ning)(ning)(ning)溫(wen)度(du)(du)(du)。適當降低冷(leng)(leng)(leng)凝(ning)(ning)(ning)溫(wen)度(du)(du)(du)對(dui)系(xi)統運行(xing)是有利(li)的(de)(de)，但同(tong)時需要增大(da)冷(leng)(leng)(leng)卻水(shui)(shui)量(liang)(liang)或風量(liang)(liang)，從而增大(da)耗(hao)功，故應(ying)全(quan)面(mian)考慮。一(yi)(yi)般(ban)控(kong)制冷(leng)(leng)(leng)凝(ning)(ning)(ning)溫(wen)度(du)(du)(du)，R22、R17系(xi)統為(wei)40℃以下。

　　怎么才能看懂(dong)高壓(ya)壓(ya)力表(biao)呢?以冷(leng)水機(ji)為(wei)例，如果冷(leng)卻水出(chu)水溫(wen)度35℃，那(nei)取冷(leng)凝(ning)溫(wen)度40℃，如果選用R22制冷(leng)劑(ji)，在壓(ya)力表(biao)對(dui)應(ying)是的外(wai)面往里數(shu)第4圈，找到對(dui)應(ying)溫(wen)度為(wei)40℃，再對(dui)應(ying)最里面一圈紅色數(shu)字，即為(wei)冷(leng)凝(ning)壓(ya)力(1.45MPa)。
