What if the air conditioner smells of smoke?

The functions of dehumidification, air supply and refreshing on the air conditioner remote controller are dehumidification, which reduces the moisture content in indoor air. The air supply, air conditioning and refrigeration systems do not work, only the fans in the indoor unit operate, so that the air circulates indoors. Refreshing means exchanging indoor air with outdoor air to keep indoor air with a certain oxygen content, or using negative ion generator to increase the negative ion content in indoor air and increase indoor comfort. When the smoke smell is very strong, you can light a candle and use the activated carbon generated when the candle burns to absorb the smoke smell. However, this method is only a stopgap measure. Carbon dioxide and smoke produced when candles burn are also harmful to human body. It is best to discourage it from smoking.
