The air conditioner was turned on well two days ago, and the wind blown out today is not too hot. It is below zero outside today. What happened?

18% of the reason is that the heating effect of the air conditioner is not the problem of the machine itself, but the improper configuration when purchasing and installing and the heating principle of the air conditioner itself.

Second, under normal circumstances, after the air conditioner has the problem of poor heating, we must first look at whether the purchased air conditioner power matches the room area. For example, an ordinary house in the south of China needs 250W of heat per square meter. If the power is not enough, the cooling effect will be worse in summer, and the heating effect of air conditioning will definitely be bad in winter.

Third, the heating effect of air conditioning is not good, except that the space size of the house does not match the power of air conditioning, the service life of the machine is too long, and the filter needs to be cleaned, and the heating effect of air conditioning itself is worse than the cooling effect. In fact, air conditioning is mainly used for refrigeration, and the heating effect is affected by the complex external environment. The heat capacity is only the data obtained by testing at the standard working temperature. If the weather is particularly cold and the outdoor temperature is lower than 0℃, the heating capacity of the air conditioner will drop rapidly. Because the air conditioner is busy defrosting the outdoor unit at this time, it cannot heat normally. At this time, it takes about 10- 15 minutes for users to turn on the air conditioner for heating, and the room temperature may drop, so some users mistakenly think that the heating effect of air conditioner is not ideal. In addition, the heating process of air conditioner is complicated, and it is necessary to switch between cooling and heating repeatedly. Low temperature starts slowly, 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 the family mainly relies on air conditioning for heating in winter, it is best to buy "electric auxiliary heating" air conditioning. Although it consumes electricity, the heating effect is relatively better. If you want high comfort, you still need to install heating.
