Cause Analysis:
(1) Poor machine airtightness, with air infiltration.
(2) Poor water quality in the water system.
(3) Excessive water content in the refrigerant or leakage inside the unit.
(4) Refrigerant not fully drained during long-term disuse.
Treatment Methods:
(1) Inspect and repair the leaking parts.
(2) Conduct water quality treatment, add corrosion inhibitors to improve water quality.
(3) Purify or replace the refrigerant, repair the leaking areas.
(4) Drain the refrigerant completely during long-term disuse.
