Is it safe to use air conditioning for warmth or cooling in a babies sleep room in a childcare centre?
Red Nose Education
Red Nose recommends dressing baby for sleep according to the room temperature.
It is not necessary to have heating & cooling on all night, but to dress the baby according to the room temperature.
ACECQA is a little more specific & has the following information.
“The care environment, including sleep and rest areas, should be well ventilated, either with fresh air from open windows if safe to do so, or using mechanical ventilation if needed.”

Mechanical ventilation may be airconditioning or a fan, but baby must still be dressed according to the room temperature, ensuring they are placed on their back for sleep with head & face uncovered (no hats)
