Why is it still cold when the air conditioner is turned on at 3 degrees?

In the two or three months when the seasonal temperature is the lowest, many friends like to turn on the air conditioner for heating. Although the temperature is set at the highest temperature of 3℃, it can be turned on for several hours continuously. Not only is the room not warm, but the warm wind blown out also makes people feel a little cold ...

Bamiancheng Technology investigates the reason. Nearly 8% of the poor heating effect of the air conditioner is not the problem of the machine itself. The main reason is that consumers are improperly configured when purchasing and installing it.

usually, after the air conditioner has the problem of poor heating, the first thing to look at is whether the purchased air conditioner power matches the room area. For example, the average domestic house in Chengdu takes 25W heat per square meter. If the power is not enough, the cooling effect will be worse in summer, and the heating effect of air conditioners in winter will definitely be bad.

the heating effect of air conditioner is not good, except that the matching between the space size of the house and the power of air conditioner is not good, the service life of the machine is too long, and the filter needs to be cleaned. Besides, the heating effect of air conditioner itself is worse than the cooling effect. In fact, air conditioning is mainly used for refrigeration, and the heating effect is affected by the complicated external environment. The heating capacity is only the data obtained by testing under the standard working temperature. If the weather is particularly cold and the outdoor temperature is lower than ℃, the heating capacity of air conditioning will drop rapidly. Because the air conditioner is busy defrosting the outdoor unit at this time, it is basically unable to heat normally. At this time, it takes about 1-15 minutes for the user to turn on the air conditioner to heat, and the room temperature may drop, and some users mistakenly think that the heating effect of the air conditioner is not ideal. In addition, the heating process of air conditioning is complicated, and it needs to be switched between cooling and heating repeatedly. It starts slowly at low temperature, and the human body is more sensitive to "cold" than "hot", so it will feel that the heating effect of air conditioning is not good.

Therefore, if families mainly rely on air conditioners for heating in winter, it is best to choose air conditioners with "electric auxiliary heating". Although it consumes electricity, the heating effect is relatively good.
