What's the most suitable opening degree of air conditioner in winter

4hw.org: many people can't wait to turn on the air conditioner for heating just after they get home in winter, and they also adjust the temperature to the maximum. In fact, it's not good to do so. It's not advisable to turn on the air conditioner too high in winter. It depends on the outdoor temperature. Let's see how much the air conditioner is suitable for winter!

How much is the indoor air conditioning suitable in winter

1. Temperature range

In winter, the indoor air conditioning temperature should be between 16 ℃ and 26 ℃, and the optimal temperature is 20 ℃. Do not overheat the indoor temperature, try to make the indoor and outdoor temperature difference less than 6 ℃, which is not only conducive to physical health, but also to avoid air conditioning overload. When heating, just start the machine with a low windscreen, and use a stroke damper half an hour later.

2. Upper temperature limit

For those who like to raise the room temperature, please be careful not to set the temperature at the extreme 30 ℃ that the air conditioner can bear in winter, otherwise it will cause frequent start or no shutdown of the air conditioner, increase the power consumption, and even damage the air conditioner compressor in serious cases. At the same time, because the heating flow is lighter than the air, it is easy to float over the whole closed room. When using the wall mounted air conditioner, it is better to adjust the air outlet to a downward angle.

3. Energy saving mode

According to the air conditioning experts, when the air conditioning heating, air conditioning temperature every 2 ℃, air conditioning can save more than 10% power. From the point of view of energy conservation, the lower the air conditioning set temperature is, of course, the better when it can ensure human body heating. Therefore, it is suggested that the air conditioning temperature should be set at about 20 ℃ in winter.

When using the air conditioner, the editor reminds you to pay attention to health. Usually, when we open the air conditioner, we close the doors and windows tightly. If the time is long, it will lead to lack of oxygen in the room, and bacteria and viruses will also accumulate in large quantities. Therefore, the air conditioner should stop and open the windows for ventilation every time it is opened for more than 2 hours.

How to prevent air conditioning disease in winter

1. Maintain regular indoor ventilation

In the air-conditioned room, open windows for ventilation at least 2 to 3 times a day for half an hour each time, which can reduce the chance of indoor bacteria breeding. In addition, if you stay in the air-conditioned room for a long time, you can go out and breathe

2. Clean the air conditioner regularly

When the air conditioner is turned on, bacteria will be blown into the air, which will enter the human body and cause various diseases. Therefore, the air conditioner must be cleaned and maintained regularly.

3. Pay attention to body water supplement

A person needs to drink 1.5 to 2 liters of water every day to avoid water shortage in a warm room. In addition to drinking water every day, choose some fruits and vegetables and non salty soup porridge, the effect of water is good. In addition, in order to prevent 'air conditioning disease', we can eat more humid and warm food, such as sesame, radish, tomato, tofu, tremella and so on.

4. Humidity in control room

Due to the use of air conditioning heating, the room is usually relatively dry. In order to control the indoor humidity, most people like to use humidifiers. Here, we need to pay attention to that, do not add tap water directly into the humidifier, it is better to add pure water, or boil the tap water, and then add it when it is cool to about 30 ℃. In addition to the use of humidifier humidification, it is best to raise more green plants, such as cacti plants. However, indoor plants should not be too many, generally one or two basins in a room.

Precautions for air conditioning temperature in winter

1. First of all, make people feel comfortable when using air conditioner

In terms of temperature, the temperature that makes people neither feel hot nor cold is called physiological zero. Physiological zero is the most comfortable temperature. Different people have different physiological zeros. For normal people in general health, physiological zero is about 28 ℃ ~ 29 ℃. Therefore, the temperature of the air-conditioned room should be selected as near as possible. In general, the best temperature of air conditioner in winter is 20 ℃, but because the outdoor temperature in each area is different, you can adjust the temperature of air conditioner according to your comfort, but it should not be too high, too high is the most unhealthy, and it will make the air conditioner work overload, shorten the life of air conditioner.

2. The use of air conditioning should be beneficial to health

The temperature difference between indoor and outdoor shall not be too large, which is generally 5 ℃ ~ 10 ℃ If the temperature difference is too large, people will suffer from sudden changes in the temperature of the gas when they enter and leave, and will easily suffer from colds and other diseases. If the temperature difference between indoor and outdoor is too large, people will easily catch cold and cold in the environment of sudden cold and sudden heat. For the elderly and people with high blood pressure, indoor and outdoor temperature difference should not be too large. Because the indoor temperature is too high, the human blood vessels dilate, and if suddenly to the outdoor, the blood vessels suddenly contract, it will make the old people and the patients with high blood pressure have trouble in cerebral blood circulation, and it is very easy to induce stroke.

3. Power saving should be considered when using air conditioner

When the temperature is adjusted too low in refrigeration or too high in heating, the energy consumption is relatively high. So in terms of power saving, you can't set the room temperature too low in summer or too high in winter.
