冷(leng)凝(ning)溫(wen)(wen)度:制冷(leng)壓縮(suo)機的總冷(leng)凝(ning)溫(wen)(wen)度是(shi)指制冷(leng)劑在冷(leng)卻(que)器(qi)內冷(leng)卻(que)后(hou)的環境溫(wen)(wen)度，對應制冷(leng)劑的蒸汽(qi)壓力(li)，即冷(leng)凝(ning)壓力(li)。對于水冷(leng)式冷(leng)凝(ning)器(qi)，其冷(leng)凝(ning)溫(wen)(wen)度一般比(bi)冷(leng)卻(que)水溫(wen)(wen)度高3-5℃。

冷(leng)(leng)凝溫(wen)(wen)(wen)度(du)是(shi)制冷(leng)(leng)系統(tong)的主要控制參(can)數(shu)之(zhi)一(yi)。在實際制冷(leng)(leng)設(she)備中，由(you)于其他(ta)結構參(can)數(shu)的改造規(gui)模較小，冷(leng)(leng)凝溫(wen)(wen)(wen)度(du)可視為一(yi)個(ge)*其重要的控制參(can)數(shu)，它(ta)直接影響制冷(leng)(leng)設(she)備的制冷(leng)(leng)效(xiao)率(lv)、安(an)全穩(wen)定性和能耗水(shui)平。蒸發環(huan)(huan)境溫(wen)(wen)(wen)度(du)是(shi)指制冷(leng)(leng)劑在蒸發器內沸騰后的環(huan)(huan)境溫(wen)(wen)(wen)度(du)。

   制(zhi)(zhi)冷機對(dui)應相(xiang)應的蒸(zheng)發(fa)(fa)(fa)(fa)壓力，蒸(zheng)發(fa)(fa)(fa)(fa)環(huan)(huan)境的溫(wen)度(du)(du)(du)是制(zhi)(zhi)冷機組中(zhong)(zhong)一個關(guan)鍵的主(zhu)要參數。蒸(zheng)發(fa)(fa)(fa)(fa)環(huan)(huan)境溫(wen)度(du)(du)(du)一般(ban)比所需溫(wen)度(du)(du)(du)低2-3℃。蒸(zheng)發(fa)(fa)(fa)(fa)溫(wen)度(du)(du)(du)是理想的冷卻(que)環(huan)(huan)境溫(wen)度(du)(du)(du)，但在(zai)實際活動中(zhong)(zhong)，制(zhi)(zhi)冷劑的蒸(zheng)發(fa)(fa)(fa)(fa)環(huan)(huan)境溫(wen)度(du)(du)(du)比冷卻(que)溫(wen)度(du)(du)(du)略低3 ~ 5度(du)(du)(du)。一般(ban)如何確定蒸(zheng)發(fa)(fa)(fa)(fa)溫(wen)度(du)(du)(du)和冷凝溫(wen)度(du)(du)(du)。

     蒸(zheng)發溫(wen)(wen)(wen)度(du)和冷(leng)(leng)凝溫(wen)(wen)(wen)度(du)根據需要確定，例如在冰(bing)箱的(de)風冷(leng)(leng)機組中(zhong)。冷(leng)(leng)凝溫(wen)(wen)(wen)度(du)主要取決于(yu)操作(zuo)溫(wen)(wen)(wen)度(du)，而蒸(zheng)發環境溫(wen)(wen)(wen)度(du)主要取決于(yu)空(kong)調的(de)應用。空(kong)調的(de)蒸(zheng)發溫(wen)(wen)(wen)度(du)越(yue)高，凍結溫(wen)(wen)(wen)度(du)越(yue)低(di)，甚至在一(yi)些超(chao)低(di)溫(wen)(wen)(wen)行業中(zhong)，標準蒸(zheng)發環境溫(wen)(wen)(wen)度(du)更低(di)。這方面(mian)沒(mei)有(you)統一(yi)的(de)主要參(can)數，主要取決于(yu)實(shi)際應用。
