Cooking will inevitably produce lampblack, and when the air conditioner is turned on, the outdoor fan will suck the lampblack in the air generated by cooking to the heat exchange fins of the outdoor heat exchanger. The existence of these lampblack will make the heat exchange capacity of the outdoor heat exchanger of the air conditioner very poor, so that the operation of the air conditioning system will be abnormal.

It is suggested that the cooking position should be as far away from the outdoor unit of air conditioner as possible.
