異常症狀簡介 / Symptom overview
冷氣滴水或漏水絕大多數源於「排水系統癱瘓」或「冷房循環異常」。當冷氣運轉時會持續產生冷凝水，若排水管被灰塵與黴菌形成的「果凍狀生物膜（水垢）」阻塞，或是管路因安裝不良導致洩水坡度消失，冷凝水就會從集水盤滿溢倒灌進入室內。另一種情況是濾網太髒導致冷風滯留在機體內，與室內溫暖空氣交會而在出風口產生異常冷凝水珠並噴出。
Indoor dripping may result from a blocked drain, drain-pan condition, incorrect pipe slope, damaged connections, poor insulation, ice formation or installation issues. Droplets at the outlet can also be related to restricted airflow and condensation. The leak location, timing and operating condition should be checked before cleaning or repair is recommended.
可能原因分析Possible causes
排水軟管內累積黏稠的果凍狀水垢（生物膜）
常見 / Common排水軟管內累積黏稠的果凍狀水垢（生物膜），導致冷凝水無法排出而滿溢。
Deposits inside the drain hose can restrict condensate flow and cause the drain pan to overflow.
檢查集水盤是否有果凍狀黏液與高水位，針對排水管進行注水與壓力測試。
Inspect the pan and water level, then test drain flow using an appropriate, non-damaging method.
濾網太髒導致回風受阻
可能 / Possible濾網太髒導致回風受阻，冷風滯留在機體內，與室內溫暖空氣交會而在出風口產生異常冷凝水珠並噴出。
A heavily blocked filter can restrict return airflow and contribute to abnormal condensation near the outlet.
打開面板檢查濾網是否完全堵塞。
Switch off the unit and inspect the filter for visible blockage.
排水管路受擠壓變形或洩水坡度不足。
少見 / Less common排水管路受擠壓變形或洩水坡度不足。
A pinched drain line or insufficient downward slope can prevent reliable drainage.
目視檢查管路走向與有無受壓迫。
Visually inspect the drain route for compression, sagging and inadequate slope.
室內機安裝不平整導致水盤水外溢。
Rare室內機安裝不平整導致水盤水外溢。
An indoor unit installed out of level may cause water to overflow the drain pan.
使用水平儀檢查室內機台安裝角度。
Check the indoor unit installation angle with a level.

需要進一步的專業評估嗎？Need a professional assessment?
若初步檢查後仍無法排除狀況，建議由洗刷刷專業技師進行現場診斷，確保空氣品質與設備效能。If initial checks do not resolve the issue, arrange an on-site diagnosis for air quality and equipment performance.
