The indoor unit of the Mijia Air Conditioner Eco EGAT Label No.5 with 1 Star 12000BTU is blowing water or mist into the room, which is caused by high humidity in the room. The cold air emitted from the indoor unit comes into contact with warmer air that has higher humidity, resulting in condensation. This is a normal phenomenon and does not require any additional action.
If the room's air humidity is too high, or if the evaporator or connecting pipe temperature is low, condensation can form on the panel and connecting pipes. This is still considered normal and does not affect the air conditioner's performance. Allowing the air conditioner to run for a while will gradually reduce humidity levels indoors.
