What's the matter with the burning smell when the air conditioner is heating? It turns out that these things are burnt
4hw.com.cn: it's generally cold in winter in China. Many friends turn on the dusty air conditioner for several months, but many children react that the heating mode of the air conditioner has a burning smell. What's going on? Let's have a look.
If the air outlet is in good condition, and the burnt smell does not belong to the smell of plastic and rubber, it usually doesn't matter, and it will be better after a while; If it is the smell of electrical appliances burning, it needs to be opened for inspection.
Air conditioning heating uses the principle of heat pump to move the outdoor heat energy indoors. Some air conditioners are supplemented by electric heating.
The temperature of heating devices is relatively high when air conditioning is heating, and the surface of these heating devices will inevitably be contaminated with dust, wool, and even some small insects, which will produce a burning smell when heated. Especially for air conditioners that have not been used for a long time in summer, due to the humidity inside during refrigeration, dust is easy to form a slurry like adhesion to components, which will taste great when heating for the first time in that year. After a period of time, the volatile substances in it will not continue to produce taste.
If the air conditioner does not blow out after a few minutes of startup, or there is a burning smell of electrical materials, the air conditioner may have a fault and should be repaired by professionals.
It's best to clean the interior of the air conditioner once or twice a year. For hanging up without use for a long time, it's best to cover the top with cloth or paper to reduce the entry of dust.
