Analysis and Testing: Open the panel, and it was found that water dripped directly from the evaporator fins. The pressure was checked at 0.3MPa (room temperature at 32℃), according to the temperature at the time, the amount of refrigerant was slightly low.
Warm Prompt: Due to the use of a multi-stage evaporator, when the refrigerant pressure is less than 0.3MPa, there will be excessive condensation on the evaporator, causing the water to not fully drain into the water tray, thus leading to leakage.

Repair Method: Inject refrigerant to make the pressure reach 0.5MPa, after running for 60 minutes, no leakage was found.
