通過萬用表、示波器等儀器檢測線路的通斷、傳感器信號的正確性等，以判斷出電氣故障的具體原因。3. 用檢漏儀檢查整個系統(tǒng)各接頭處泄漏與否。4. 用溫度計能夠判斷出蒸發(fā)器、冷凝器、儲液器故障。蒸發(fā)器正常工作時，其表面溫度在不結霜的前提下越低越好。冷凝器正常工作時，其入口管溫度是70℃左右，出口管溫度是50℃左右。儲液器正常情況下應是50℃左右，如果儲液筒上下溫度不一致，則說明儲液器有堵塞。5. 把壓力表別接在壓縮機的排氣口及吸氣口的維修閥上。</p><p

3.如在冷卻水、冷凝水中檢出嗜肺軍團菌，或風管內表面積塵量、細菌總數(shù)、細菌總數(shù)有不符合衛(wèi)生要求的應立即對空調通風系統(tǒng)進行清洗消毒。集中空調通風系統(tǒng)本身就是一個藏污納垢的地方，長期不清洗消毒，不但會降克制冷效果，能耗增加外，還可能造成空氣傳播性疾病的爆發(fā)流行、過敏性疾病、不良建筑物綜合征等方面對人體的影響。重度污染是嚴重的，當打開壓縮機的工藝管時時，立即可聞到焦油味。黃浦區(qū)空調冷卻水檢測機構推薦</p><p
