How to judge whether the hotel air conditioner can be turned on during the epidemic?

Determine the type of air conditioner.

Two-way air inlet and outlet, the introduction of fresh air and the discharge of dirty air are all carried out through ventilation equipment, and the introduction of fresh air is in a clean outdoor place. This type of fresh air in the hotel can be used normally during the epidemic.

One-way air inflow, fresh air equipment introduces fresh air from outside, forms positive pressure indoors, and indoor dirty air is discharged from the gap between doors and windows. This type of fresh air in the hotel can be used normally during the epidemic.

Centralized return air is supplied separately, and there is a separate air inlet indoors, but the air outlet is in public areas such as corridors. This type of fresh air will be closed during the epidemic.
