How many degrees is the best for air conditioning heating? Blow carefully when the temperature is to

Air conditioning heating at 20 ℃ is the most appropriate, because in winter, the indoor temperature of 20 ℃ is not only the most suitable and warmest temperature, but also can avoid the overload operation of air conditioning, which is also beneficial to people's health. From the comfort point of view, air conditioning heating at 18 ℃ to 20 ℃ is the best.

The national heating standard is 16-18. For families, if there is no special requirement for the setting of air conditioning, it is generally appropriate to set it at 16-18.

The reason why you said the air conditioner will stop in a few minutes after starting up is that when the air conditioner is heating in winter, it will frost outdoors. When the air conditioner feels that the temperature collection is not good, it will frost automatically. When defrosting, the air conditioner will operate in refrigeration mode. If the air conditioner has the chance to dissipate heat, it will naturally defrost. After frost is removed, the air conditioner will automatically switch to heating mode.

According to scientific calculation, if the room temperature is set as high as 1 ℃ in refrigeration and as low as 2 ℃ in heating, more than 10% of the electricity can be saved, but the human body can hardly detect this tiny difference. After the temperature is designed, the wind speed must be set again. According to the current room temperature, when the air conditioner is just turned on, the wind speed will be higher. When the temperature reaches the design temperature, the wind speed will be lower. This will reduce noise and save energy.

1. Comfortable temperature of human body

From the perspective of human comfort, in winter indoor environment, if the indoor temperature is controlled between 18-20 ℃, people will feel comfortable. Because in winter, people wear more clothes, if the indoor temperature is higher than 20 ℃, it will feel a little hot. If the air conditioning temperature in winter is set above 26 ℃, the heating temperature in winter is too high, which will make the indoor air extremely dry, hurt the body fluid and body fluid, and make people feel hot and dry, and the skin of eyes, ears, mouth, nose and throat feel dry.

2. Human health care temperature

From the perspective of health care, at least two problems should be paid attention to when using air conditioning in winter: first, the temperature difference between indoor and outdoor should not be too large, and it is better to keep the indoor air conditioning temperature 8 ℃ higher than outdoor air conditioning temperature in winter. If the temperature difference between indoor and outdoor is too large, people are easy to catch cold in the environment of sudden cold and heat; for the elderly and people with hypertension, the temperature difference between indoor and outdoor should not be too large. Because the indoor temperature is too high, human blood vessels dilate, and at this time, if suddenly outside, blood vessels suddenly contract, will make the elderly and patients with hypertension cerebral blood circulation obstacles, easily induce stroke.

3. More than 10% energy can be saved every 2 ℃ lower

According to experts, the air conditioner can save more than 10% electricity when the temperature is set down by 2 ℃ in winter. From the point of view of energy saving, the lower the setting temperature of air conditioner is, the better.

Therefore, considering many factors, it is suggested that the air conditioning temperature should be set at about 20 ℃ in winter.

Extended reading: the reason why air conditioner doesn't heat

1. When the air conditioner can't heat up, you can check whether there is too much dust in the air filter of the air conditioner first, because the air vent of the meter and the inner machine is most easily blocked by foreign matters, as long as you dredge the heating here.

2. If it's not the problem of the air vent blocking in the meter, it may be that the outdoor temperature is too low or the power consumption environment is poor.

3. There is no problem with the former two. It may be that there are too many or too few freons in the air conditioner. At this time, professional repair personnel are needed to deal with them.

4. None of the above problems, that is, the heating power of the air conditioner is too small.
