Is the strong smell of new air conditioners caused by formaldehyde?
The strong smell of new air conditioners is not caused by formaldehyde.
Almost all parts of the air conditioner itself do not contain formaldehyde, and no formaldehyde is produced during the operation of the air conditioner. The main sources of formaldehyde in the room are furniture, paint, glue, etc. The heat exchanger of the air conditioner indoor unit is made of aluminum and copper and is not bonded with glue, so there is no basis for generating formaldehyde. However, when the air conditioner is turned on, the air flow in the room will be accelerated, and the original formaldehyde gas in the room will be relatively evenly distributed throughout the room.

3. This is because after the new air conditioning system is started, the indoor bacterial concentration and odor will increase. A large amount of gas generated when microorganisms multiply is suddenly released due to the driving of the air conditioning system, becoming one of the causes of odor. .
