冷(leng)(leng)(leng)(leng)(leng)(leng)凝溫(wen)度(du)(du)(du):制冷(leng)(leng)(leng)(leng)(leng)(leng)壓(ya)縮(suo)機的(de)總(zong)冷(leng)(leng)(leng)(leng)(leng)(leng)凝溫(wen)度(du)(du)(du)是指(zhi)制冷(leng)(leng)(leng)(leng)(leng)(leng)劑在冷(leng)(leng)(leng)(leng)(leng)(leng)卻(que)器(qi)內冷(leng)(leng)(leng)(leng)(leng)(leng)卻(que)后(hou)的(de)環境溫(wen)度(du)(du)(du)，對應制冷(leng)(leng)(leng)(leng)(leng)(leng)劑的(de)蒸汽壓(ya)力，即(ji)冷(leng)(leng)(leng)(leng)(leng)(leng)凝壓(ya)力。對于(yu)水(shui)冷(leng)(leng)(leng)(leng)(leng)(leng)式(shi)冷(leng)(leng)(leng)(leng)(leng)(leng)凝器(qi)，其冷(leng)(leng)(leng)(leng)(leng)(leng)凝溫(wen)度(du)(du)(du)一般比冷(leng)(leng)(leng)(leng)(leng)(leng)卻(que)水(shui)溫(wen)度(du)(du)(du)高(gao)3-5℃。

冷凝溫度是(shi)(shi)制(zhi)(zhi)冷系統的主要(yao)控(kong)制(zhi)(zhi)參(can)數(shu)之一(yi)。在實(shi)際(ji)制(zhi)(zhi)冷設備(bei)中(zhong)，由于其(qi)他(ta)結構參(can)數(shu)的改造(zao)規模較(jiao)小，冷凝溫度可視為一(yi)個*其(qi)重要(yao)的控(kong)制(zhi)(zhi)參(can)數(shu)，它直接影響制(zhi)(zhi)冷設備(bei)的制(zhi)(zhi)冷效率(lv)、安全穩定性和(he)能耗水平。蒸發(fa)環(huan)(huan)境(jing)溫度是(shi)(shi)指制(zhi)(zhi)冷劑在蒸發(fa)器內(nei)沸騰后的環(huan)(huan)境(jing)溫度。

   制(zhi)冷(leng)機對應相(xiang)應的蒸(zheng)發(fa)壓力，蒸(zheng)發(fa)環(huan)境的溫(wen)度是(shi)制(zhi)冷(leng)機組中一(yi)(yi)個關鍵的主要參數(shu)。蒸(zheng)發(fa)環(huan)境溫(wen)度一(yi)(yi)般比所需溫(wen)度低2-3℃。蒸(zheng)發(fa)溫(wen)度是(shi)理想的冷(leng)卻環(huan)境溫(wen)度，但在實際活(huo)動(dong)中，制(zhi)冷(leng)劑的蒸(zheng)發(fa)環(huan)境溫(wen)度比冷(leng)卻溫(wen)度略低3 ~ 5度。一(yi)(yi)般如何確定蒸(zheng)發(fa)溫(wen)度和冷(leng)凝溫(wen)度。

     蒸(zheng)發溫(wen)(wen)(wen)度(du)(du)和冷(leng)凝溫(wen)(wen)(wen)度(du)(du)根(gen)據需要(yao)(yao)確定，例如在冰(bing)箱(xiang)的風(feng)冷(leng)機組(zu)中。冷(leng)凝溫(wen)(wen)(wen)度(du)(du)主(zhu)要(yao)(yao)取決于操(cao)作(zuo)溫(wen)(wen)(wen)度(du)(du)，而蒸(zheng)發環(huan)境(jing)溫(wen)(wen)(wen)度(du)(du)主(zhu)要(yao)(yao)取決于空調的應用。空調的蒸(zheng)發溫(wen)(wen)(wen)度(du)(du)越高，凍結溫(wen)(wen)(wen)度(du)(du)越低，甚至在一(yi)些超(chao)低溫(wen)(wen)(wen)行業中，標(biao)準蒸(zheng)發環(huan)境(jing)溫(wen)(wen)(wen)度(du)(du)更低。這方面沒有(you)統(tong)一(yi)的主(zhu)要(yao)(yao)參數，主(zhu)要(yao)(yao)取決于實際應用。
