冷(leng)(leng)(leng)(leng)凝(ning)溫(wen)(wen)度(du):制冷(leng)(leng)(leng)(leng)壓(ya)縮機的總(zong)冷(leng)(leng)(leng)(leng)凝(ning)溫(wen)(wen)度(du)是指(zhi)制冷(leng)(leng)(leng)(leng)劑在(zai)冷(leng)(leng)(leng)(leng)卻器內(nei)冷(leng)(leng)(leng)(leng)卻后的環境溫(wen)(wen)度(du)，對應制冷(leng)(leng)(leng)(leng)劑的蒸汽壓(ya)力，即冷(leng)(leng)(leng)(leng)凝(ning)壓(ya)力。對于水(shui)冷(leng)(leng)(leng)(leng)式冷(leng)(leng)(leng)(leng)凝(ning)器，其(qi)冷(leng)(leng)(leng)(leng)凝(ning)溫(wen)(wen)度(du)一(yi)般比(bi)冷(leng)(leng)(leng)(leng)卻水(shui)溫(wen)(wen)度(du)高3-5℃。

冷(leng)凝(ning)溫度(du)是制冷(leng)系統的主(zhu)要(yao)(yao)控制參數(shu)之(zhi)一。在(zai)實際制冷(leng)設備(bei)中，由于其他結構(gou)參數(shu)的改造規模較(jiao)小，冷(leng)凝(ning)溫度(du)可視為一個*其重要(yao)(yao)的控制參數(shu)，它直接影響制冷(leng)設備(bei)的制冷(leng)效(xiao)率、安全穩定性和能耗(hao)水平。蒸(zheng)發(fa)環境(jing)溫度(du)是指(zhi)制冷(leng)劑在(zai)蒸(zheng)發(fa)器內沸騰后的環境(jing)溫度(du)。

   制冷機對應(ying)相應(ying)的蒸(zheng)(zheng)發(fa)(fa)壓力，蒸(zheng)(zheng)發(fa)(fa)環(huan)(huan)境(jing)的溫(wen)(wen)(wen)(wen)度(du)(du)(du)(du)是制冷機組中一個關鍵的主要(yao)參數。蒸(zheng)(zheng)發(fa)(fa)環(huan)(huan)境(jing)溫(wen)(wen)(wen)(wen)度(du)(du)(du)(du)一般比所(suo)需溫(wen)(wen)(wen)(wen)度(du)(du)(du)(du)低2-3℃。蒸(zheng)(zheng)發(fa)(fa)溫(wen)(wen)(wen)(wen)度(du)(du)(du)(du)是理想的冷卻環(huan)(huan)境(jing)溫(wen)(wen)(wen)(wen)度(du)(du)(du)(du)，但在實際活(huo)動(dong)中，制冷劑(ji)的蒸(zheng)(zheng)發(fa)(fa)環(huan)(huan)境(jing)溫(wen)(wen)(wen)(wen)度(du)(du)(du)(du)比冷卻溫(wen)(wen)(wen)(wen)度(du)(du)(du)(du)略低3 ~ 5度(du)(du)(du)(du)。一般如何確(que)定蒸(zheng)(zheng)發(fa)(fa)溫(wen)(wen)(wen)(wen)度(du)(du)(du)(du)和(he)冷凝溫(wen)(wen)(wen)(wen)度(du)(du)(du)(du)。

     蒸發(fa)溫(wen)度(du)(du)(du)和冷凝(ning)(ning)溫(wen)度(du)(du)(du)根據需要(yao)確定，例如在冰箱的(de)風冷機組中。冷凝(ning)(ning)溫(wen)度(du)(du)(du)主要(yao)取決(jue)于操作溫(wen)度(du)(du)(du)，而蒸發(fa)環(huan)(huan)境溫(wen)度(du)(du)(du)主要(yao)取決(jue)于空(kong)調(diao)的(de)應用。空(kong)調(diao)的(de)蒸發(fa)溫(wen)度(du)(du)(du)越高，凍結溫(wen)度(du)(du)(du)越低(di)，甚至在一(yi)些超(chao)低(di)溫(wen)行(xing)業中，標準(zhun)蒸發(fa)環(huan)(huan)境溫(wen)度(du)(du)(du)更低(di)。這方面沒有統一(yi)的(de)主要(yao)參數(shu)，主要(yao)取決(jue)于實(shi)際應用。
