泄露是蒸(zheng)發器(qi)多見的缺點(dian)景象，在(zai)運用(yong)(yong)(yong)過程中(zhong)應留意經常檢(jian)漏(lou)。對泄露處可用(yong)(yong)(yong)酚(fen)酞試紙檢(jian)查，因為氨是堿(jian)性(xing)，遇酚(fen)酞試紙變(bian)紅。用(yong)(yong)(yong)眼(yan)看時(shi)，一般在(zai)蒸(zheng)發器(qi)的某處不結(jie)霜的本地便是泄露點(dian)，也可在(zai)泄露處用(yong)(yong)(yong)肥皂水找(zhao)漏(lou)。氟利(li)昂蒸(zheng)發器(qi)泄露的檢(jian)查可運用(yong)(yong)(yong)鹵(lu)素燈(deng)和鹵(lu)素檢(jian)漏(lou)儀，也可用(yong)(yong)(yong)肥皂水找(zhao)漏(lou)。

檢查(cha)時(shi)(shi)(shi)可先用眼蒸發排管上是(shi)不是(shi)有(you)(you)油跡，因為(wei)氟利昂與油能互溶，氟利昂泄(xie)露(lu)(lu)時(shi)(shi)(shi)，有(you)(you)也會從漏(lou)點(dian)滲出。用鹵(lu)素(su)燈(deng)檢漏(lou)時(shi)(shi)(shi)，若某(mou)有(you)(you)氟利昂泄(xie)露(lu)(lu)，鹵(lu)素(su)燈(deng)焚燒(shao)的火(huo)焰(yan)有(you)(you)藍色(se)便(bian)成(cheng)微綠、淺(qian)綠、草綠、紫綠、紫色(se)等色(se)彩可區分氟利昂泄(xie)露(lu)(lu)多少(shao)。若火(huo)焰(yan)出現深綠或(huo)紫色(se)時(shi)(shi)(shi)，火(huo)焰(yan)中的光氣有(you)(you)毒(du)，不能長(chang)時(shi)(shi)(shi)間用此方法檢查(cha)。
