The hotel has cold air, but it doesn't feel cold.

Air conditioning, refrigeration and heating all need enough freon.

If there is less freon, it will lead to the problem that the air conditioner can't produce cold air or the refrigeration effect is very poor.

Therefore, after we find that the air conditioner can't produce cold air, we must first judge whether the freon in the air conditioner is sufficient. If it is insufficient, it needs to be supplemented in time. If it is enough, other reasons should be considered. Sometimes the air conditioner can't produce cold air because the outdoor temperature is too high, because if the outdoor temperature is high and the outdoor unit of the air conditioner is not ventilated, it will affect the refrigeration effect of the air conditioner, so remember to take this into account when considering the reasons.
