What's the right temperature for air conditioning in hot weather?

Question 1: How many degrees of air conditioning is suitable for human body in summer? The most suitable air conditioning temperature is 24℃-27℃

So how big should the air conditioner be turned on and what is the most suitable air conditioning temperature for the human body? The most suitable air conditioning temperature for human body should be 24℃ to 27℃, the lowest temperature should not be lower than 22℃, the indoor and outdoor temperature difference should not be greater than 5℃, and the air conditioning at night should not be lower than 24℃. If the air conditioner is turned on too much and the indoor temperature is too low, it is easy to suffer from "air conditioning diseases", such as colds, coughs, fever and listlessness. Han analyzed that there are several main reasons for "air conditioning disease":

The temperature difference between indoor and outdoor is too large. If people come in and out frequently, it will easily lead to the dysfunction of the balance regulation system in the body. At first glance, when entering and leaving the air-conditioned room, sweat pores suddenly open and close, sweating function is abnormal, perspiration is reduced, and waste in the body is not easy to discharge. Sweating is the most important function of the human body to maintain normal health in summer, and people can't help sweating in summer.

Air-conditioned rooms are closed, indoor and outdoor air cannot be exchanged, harmful microorganisms such as bacteria and viruses in indoor air are easy to breed, and the air quality is low. In the long run, it is easy to reduce the body's own immune function, and it is also easy to get sick due to bacterial infection. Han Xiaoke said that due to the lack of fresh air in air-conditioned rooms, people sneeze less, and sneezing is the normal defense function of the respiratory tract. It can eliminate germs and secretions hidden in the nasal cavity, and prevent these bacteria from spreading downwards, causing people to suffer from pharyngitis and chronic tracheitis. Staying in an air-conditioned environment for a long time, some people will have allergic reactions and runny noses.

Generally, central air conditioning can only cool down but not dehumidify. With the arrival of summer weather in July and August, it is not only high temperature, but also high humidity and low pressure. For example, if there are two days with the same high temperature of 39℃, one day the humidity is 40%, and the other day the humidity is 32%, then people will feel more sultry on that day with high humidity. Turning on the air conditioner at this time will make more people feel unwell, backache, loss of appetite and fatigue.

As for whether the phenomenon you said is normal or not.

Supplementary question: Office staff:

The room temperature of the air-conditioned room is 26℃

At present, many units have used air conditioning. People can easily suffer from "air conditioning disease" if they use air conditioning unreasonably while enjoying the cool breeze.

It is often seen that young people and overweight people keep the air conditioner on all day at home, or come into the house sweating from the outside, and the temperature is very low. Some people even run under the air conditioner and blow directly for a while, but they don't know that when blowing directly, the wind speed will increase and the temperature will suddenly drop, causing dizziness and headache. People who often sit in air-conditioned rooms say, "I feel dizzy, see stars, and forget things." This is an imbalance of brain nerves caused by air conditioning disease.

Owner:

Don't get on the bus and turn on the air conditioner.

In hot summer, car owners can enjoy some happiness, because there is air conditioning in the car to cool down, so many anxious young people turn on the air conditioner as soon as they get on the bus, or adjust the air conditioning temperature to the lowest indefinitely. But you should know that these are all wrong practices.

In the car, people are closer to the air conditioner. If the temperature is too low for a long time, it may lead to arthritis, scapulohumeral periarthritis, colds and other diseases. Moreover, when the air conditioner is turned on in the car, it is mostly airtight, and the air circulation is not very good. Air conditioning itself will also emit some harmful gases. If you stay in such an environment for a long time, you will naturally get sick. Generally speaking, it is appropriate to keep the difference between indoor temperature and outdoor temperature at 10 degrees.

Question 2: How high is the air conditioner? Summer: consider saving energy by 26-28 degrees Celsius.

The most suitable air conditioning temperature for human body is 24℃-27℃, so how big should the air conditioner be turned on and what is the most suitable air conditioning temperature for human body? The most suitable air conditioning temperature for human body should be 24℃ to 27℃, the lowest temperature should not be lower than 22℃, the indoor and outdoor temperature difference should not be greater than 5℃, and the air conditioning at night should not be lower than 24℃. If the air conditioner is turned on too much and the indoor temperature is too low, it is easy to suffer from "air conditioning diseases", such as colds, coughs, fever and listlessness.

Winter: 15- 18℃.

In the indoor environment in winter, people will feel comfortable if the indoor temperature is controlled between 15 degrees Celsius and 18 degrees Celsius. Because in winter, people wear a lot of clothes. If the indoor temperature is higher than 18 degrees Celsius, they will feel a little hot but uncomfortable. So don't set the air conditioning temperature too high.

Question 3: How high is the air conditioner in summer? The comfortable temperature of the body is about 25-28 degrees. So it's best to keep it within this temperature and save electricity.

Air conditioning power saving mainly depends on the "operating rate", that is, it consumes the most power when it is turned on, so don't turn it on and off frequently.

The air tightness of air-conditioned rooms must be better, and the windows should be closed tightly to prevent the loss of cold air.

When setting the room temperature, don't differ too much from the outdoor temperature, such as 30℃ outdoor and 25℃ indoor. If you don't feel cold, you can lower the set temperature by a few degrees, so that the high-frequency operation time of the air conditioner is short and it saves electricity. It should be pointed out that some people often turn on the air conditioner and turn it off in order to save electricity. In fact, frequent switching of air conditioners consumes the most power, and compressors are also prone to loss.

Air-conditioning filter should be cleaned frequently, otherwise the blockage of the net cover will also affect the refrigeration effect.

Adjust the temperature setting

Before turning on the air conditioner, the temperature setting can be raised by 5~ 10 minutes, and maintaining air supply can save electricity.

When installing air conditioning, try to choose a shady room or a shady side of the room to avoid direct sunlight. If this condition is not met, a sunshade should be added to the air conditioner.

In air-conditioned rooms, it is best to hang thick curtains to prevent the exchange of cold and hot air indoors and outdoors.

When turning on the air conditioner, the temperature should not be set too low, otherwise it will consume electricity and easily make people catch a cold.

Don't leave the air conditioner on from morning till night. It is best to stop when the temperature is low in the morning, which can save electricity and adjust the indoor air.

Dust on the air conditioning filter screen should be removed frequently, so that on the one hand, the air can be kept clean, on the other hand, the air circulation system can be kept smooth, and the purpose of saving electricity can be achieved.

The shorter the connecting pipe between indoor unit and outdoor unit of split air conditioner, the better, so as to reduce power consumption, and the connecting pipe should be insulated.

Regularly clean the dust on the heat sink of the outdoor unit, because too much dust will increase the power consumption of the air conditioner, and even cause the compressor to overheat and the protector to trip.

Choose the air conditioning type according to the housing area. At present, it is generally calculated according to the cooling capacity of 200W per square meter.

Try to avoid adjusting the cooling temperature of the air conditioner to a minimum. The comfortable temperature of human body is about 25-28 degrees.

Close the doors and windows after air conditioning during the examination to prevent indoor and outdoor air heat exchange, resulting in air conditioning loss. It is best to put down the curtains during the day to prevent the sun from generating higher heat.

Regularly ask professionals to clean the filter screen of the indoor unit and the condenser of the outdoor unit to keep the air conditioner in good working condition.

Using the fixed switch function of air conditioner, turn off the air conditioner regularly after falling asleep, and turn on the air conditioner at midnight 1-2 hours, which can effectively avoid frequent start-up of air conditioner all night and achieve the effect of saving electricity.

Frequency conversion air conditioner effectively avoids the power consumption waste caused by repeated start-up of air conditioner by using its characteristics of frequency conversion and output adjustment ability.

Question 4: How high is the air conditioner at home in summer?

Don't turn the degree too low.

Many people feel hot at first, so they want to turn the air conditioner to the minimum immediately, hoping to cool down immediately. This is very bad, because if it is too fast, the body may not be able to adapt, and it is easy to have bad symptoms such as headache, cold sweat and fatigue.

Don't be too different from the outdoor temperature.

When adjusting the indoor temperature, it is best not to differ too much from the outdoor temperature, but within 5-7 degrees. If the difference is too big, you will feel very hot when you go out and very cold when you come back.

Take care of the elderly and children when adjusting the temperature.

If there are old people or children at home, don't turn on the air conditioner to cool down, because the old people and children have poor temperature regulation ability and are easily affected by air conditioning and cause colds or physical discomfort.

The general temperature is 26-28 degrees.

The temperature of 26-28 degrees is a comfortable gradient for the body, and it is also more environmentally friendly and energy-saving. If it is not particularly hot, the air conditioner can turn on the temperature of 26-28 degrees in summer.

Adjust the air conditioning temperature according to the time period.

Generally, the outdoor temperature will be different in each time period. It will be very hot at noon and afternoon, and it will be a little cooler in the morning and evening. If you turn on the air conditioner at home, you can turn it down at noon and afternoon, and turn it up at 1-2 degrees in the morning and evening.

The temperature of sleeping at night should not be lower than 25 degrees.

Many people are used to sleeping with the air conditioner on at night, because they can fall asleep cold, but remember that the temperature should not be adjusted too low, so it is easy to catch a cold. You can set the time, or open the window to sleep naturally.

Matters needing attention

When you turn on the air conditioner, you can't blow into it;

Pregnant women, the elderly and children should not use air conditioners for a long time;

Question 5: How many degrees can the air conditioner be turned on in summer? The state stipulates that the set temperature of air conditioner in summer shall not be lower than 26℃; It shall not be higher than 20℃ in winter.

In summer, the air conditioner can only work when the set temperature is lower than the indoor temperature.

In winter, the air conditioner can only work when the set temperature is higher than the indoor temperature.

Therefore, according to national regulations, when the indoor temperature is higher than 26 degrees Celsius in summer, air conditioning can be turned on for refrigeration; In winter, the indoor temperature is below 20 degrees Celsius, so you can turn on the air conditioner to keep warm.

Question 6: What is the optimal temperature of air conditioner in summer? When using air conditioning, it is not advisable to set the temperature too low. The summer temperature of domestic air conditioner recommended by the state is 26-27 degrees, and the electricity load can be reduced by 7% to 1 0% when the air conditioner is raised1degree. From the health point of view, the indoor and outdoor temperature difference in midsummer is preferably 4-5 degrees. If people often go in and out, it will be cold and hot, sweat gland pores will suddenly open and close, perspiration function will be abnormal, perspiration will be reduced, and it will be difficult to discharge waste in the body, which will easily lead to dysfunction of the balance regulation system in the body, which is not only harmful to human health, but may even lead to so-called "air conditioning diseases", such as arthritis, scapulohumeral periarthritis, gastroenteritis, colds and so on.

Question 7: What is the best temperature to turn on the air conditioner in summer? For people who do light work, when the air conditioner is set at 26℃, the indoor humidity is about 50%, which is more suitable for the human body and makes the human body feel more comfortable. The most suitable air conditioning temperature for human body is also 24℃ to 27℃. Driving to 26-28℃ at night in summer is most suitable for energy saving. The temperature difference between indoor and outdoor should not be greater than 5℃, which is easy to cause air conditioning disease. When the air conditioner is cooling, raising the temperature by 2℃ can save electricity by 20%.

Question 8: What is the optimum temperature for indoor air conditioning in summer? In summer, it is advisable to set the air conditioning temperature at 3-5 degrees lower than the outdoor temperature. Too large a temperature difference is easy to make people uncomfortable, especially for children who are prone to air conditioning. The normal temperature of human body needs a relatively stable temperature environment, and the temperature difference between indoor and outdoor is too large, which is easy to cause body temperature imbalance. If the air conditioning temperature is adjusted too low and the cool wind blows for too long, it will lead to diseases such as energy storage, dizziness, cold or arthritis recurrence. For this reason, experts remind that the indoor and outdoor temperature difference should not be too large. Generally speaking, it is appropriate to adjust the air conditioner to 25-27 degrees Celsius and the humidity to 50-60% in summer.

Question 9: How many degrees does the country require to turn on the air conditioner in summer? Does the country have such regulations or suggestions, and how many degrees can the air conditioner be turned on in summer and winter? If not, it's like there are no rules! But it is much more open at 30 degrees, and it is also around 1 degree in winter.

Question 10: Turn on the air conditioner in summer. What is the most energy-saving and appropriate driving temperature during the day and at night? First of all, relevant experts believe that 26℃ is a comfortable and not easy to get sick. The indoor and outdoor temperature difference should not be too large, generally around 8℃ to 10℃. Although there may be hot weather above 38℃ in summer, the temperature is below 35℃ for most of the day, so the indoor temperature is about 26℃.

Secondly, 26 degrees is a relatively energy-saving summer temperature setting. When the indoor temperature is designed, every increase of 1℃ can save energy by about 5%-7%, and an increase of 2℃ can save energy by at least 10%. In summer, air conditioning is the main energy-consuming refrigeration tool for buildings. The air conditioner of the whole society can be raised to 26℃, which can greatly alleviate the shortage of electricity in summer and reduce the greenhouse gas emissions during power generation.

1, the air conditioning temperature is set at 26℃, which not only ensures human comfort, but also helps to save energy. Every time the air conditioner rises 1℃, it can save electricity by 5%-8%.

2. Keep the air conditioner in a good environment. Air-conditioned rooms should be airtight (of course not airtight). Do not use high-power incandescent lamps or traditional fluorescent lamps in air-conditioned rooms, and try to use energy-saving lamps.

3. Use energy-saving air conditioners. When buying refrigeration equipment, try to buy products with high efficiency.
