At what temperature do you need to turn on the air conditioner?

Question 1: How much should the air conditioner be turned on? Summer: consider energy saving 26-28 degrees Celsius

The most suitable air-conditioning temperature for the human body is 24℃-27℃. So how high should the air conditioner be turned on? What is the most suitable air-conditioning temperature for the human body? The most suitable air conditioning temperature for the human body should be between 24°C and 27°C, and the minimum should not be lower than 22°C. The indoor and outdoor temperature difference should not be greater than 5°C, and the air conditioning temperature at night should not be lower than 24°C. If the air conditioner is turned on too high and the indoor temperature is too low, it is easy to suffer from "air conditioning disease", such as colds, coughs, fevers, lack of energy, etc.

Winter: 15-18 degrees Celsius

In a winter indoor environment, people will feel comfortable if the indoor temperature is controlled between 15 degrees Celsius and 18 degrees Celsius. Because in winter, people wear more clothes. If the indoor temperature is higher than 18 degrees Celsius, they will feel a little hot and uncomfortable. Therefore, the air conditioner temperature should not be set too high.

Question 2: At what temperature is it appropriate to turn on the air conditioner? We are allowed to turn on the air conditioner when the room temperature is 29 degrees, and turning on the air conditioner at 26 degrees is uniformly stipulated above and should be more reasonable.

Question 3: How high the indoor temperature is considered to be high and the air conditioner must be turned on varies from person to person

Question 4: What is the appropriate degree to turn on the air conditioner? Air conditioning refrigeration is limited by the indoor temperature of the room. The temperature set by the remote control is the indoor temperature. , but the set temperature cannot be lower than the outdoor temperature, otherwise it will not turn on. If the temperature is set high, it will be turned on and off frequently, which is not good for the air conditioner. If it is set low, it will not stop for a long time, so the temperature set for air conditioning cooling in summer is average. It is normal if the temperature is between 25-27 degrees. In winter, air conditioning heating is generally not limited by the temperature set by the remote control. The temperature sensor head of the air conditioner is sensitive to cooling sensitivity and slightly less sensitive to heating. Therefore, it is normal for the temperature of the heating remote control to be set at 30 degrees Celsius in winter.

Note: Regardless of cooling or heating, the temperature setting should also consider the cooling capacity and heating capacity of the air conditioner. If the room is large and the cooling capacity of the air conditioner is small, the temperature setting should be To lower the temperature, the heating is still set to the highest temperature on the remote control.

Question 5: At what temperature should the air conditioner be turned on? Generally, the air conditioner can be turned on above 30 degrees, and the air conditioner temperature is set to 22-28 degrees. 1. If the air conditioner is cooled by 2 degrees Celsius less, you can save about 10% of electricity. 2. When cleaning the air conditioner, be sure to clean the dust filter carefully, because if the dust filter mesh is clogged, the cooling and heating effect of the air conditioner will be reduced. Generally speaking, it should be cleaned once every two weeks. 3. Use the timer effectively. When sleeping or going out, pay attention to using the timer so that it runs within the necessary time, so that you do not have to run the air conditioner all the time, which can save electricity. 4. Do not block the air outlet of the outdoor unit. If the air outlet of the outdoor unit is blocked by objects, the cooling and heating effect will be reduced, which will lead to great waste.

Question 6: At what temperature does the state stipulate that the air conditioner can be turned on in summer? Does the country have such regulations or recommended temperatures for operating air conditioners in summer and winter? If not, there seems to be no regulations! But when it goes up to 30 degrees, it is turned on a lot. In winter, it is also turned on at about 1 degree. Question 7: How much should the air conditioner be turned on in summer? What is the most suitable air conditioner for the human body The temperature is 24℃-27℃

So how high should the air conditioner be turned on? What is the most suitable air conditioning temperature for the human body? The most suitable air conditioning temperature for the human body should be between 24°C and 27°C, and the minimum should not be lower than 22°C. The indoor and outdoor temperature difference should not be greater than 5°C, and the air conditioning temperature at night should not be lower than 24°C. If the air conditioner is turned on too high and the indoor temperature is too low, it is easy to suffer from "air conditioning disease", such as colds, coughs, fevers, lack of energy, etc. Han Xiaoqian analyzed that there are several main causes of "air-conditioning disease":

The temperature difference between indoor and outdoor is too large. If people come in and out frequently and are hot and cold, it is easy to cause dysfunction of the body's homeostasis regulation system. As soon as you enter or leave an air-conditioned room, your sweat pores suddenly open and close, resulting in dysfunction of the perspiration function, reduced sweating, and difficulty in expelling waste from the body. Sweating is the most important function of the human body to maintain normal health in summer. People cannot help but sweat in summer.

Air-conditioned rooms are tightly sealed, and indoor and outdoor air cannot be exchanged. Harmful microorganisms such as bacteria and viruses in indoor air can easily breed and multiply. The air quality is low. If things go on like this, it will easily reduce the body's own immune function and make it susceptible to germs. Get sick from infection. Han Xiaoke said that due to the poor air circulation in air-conditioned rooms and the lack of fresh air***, people sneeze less often, and sneezing is a normal defensive function of the respiratory tract. It can eliminate germs and secretions hidden in the nasal cavity, without Let these bacteria spread downward, causing people to suffer from pharyngitis, chronic tracheitis, etc. After staying in an air-conditioned environment for a long time, some people may develop allergic reactions and runny noses.

Central air conditioners generally can only cool down but not dehumidify. With the arrival of summer weather in July and August, it is not only high temperatures that are causing trouble, but more importantly, higher humidity and lower air pressure. For example, if there are two days with the same high temperature of 39°C, and the humidity is 40% on one day and 32% on the other day, people will feel even hotter and unbearable on the day with high humidity. At this time, no matter how high the air conditioner is, it will cause more people to feel discomfort, back pain, loss of appetite, and fatigue.

As for whether the phenomenon you mentioned is normal

Additional questions: Office workers:

The appropriate room temperature in air-conditioned rooms is 26°C

At present, Many units have air conditioning. While people are enjoying the cool breeze, they are also prone to suffer from "air conditioning disease" if they use air conditioners unreasonably.

It is common to see young people and fat people turning on the air conditioner at home all day long, or sweating profusely when they come in from the outside and set the temperature very low. Some people even run to the air conditioner. The direct blowing from below is just for temporary pleasure. However, when blowing directly, the air flow speed increases and the temperature will drop suddenly, causing dizziness and headache. People who often sit in air-conditioned rooms say, "I feel dizzy, have stars in my eyes, and forget things." This is the brain nerve imbalance reaction caused by air-conditioning disease.

Car owners:

Don’t turn on the air conditioner when you get in the car

Car owners can enjoy a little blessing in the hot summer, because the car has air conditioner to cool it down It is cool, so many impatient young people turn on the air conditioner as soon as they get into the car, or adjust the air conditioner temperature to the lowest limit. But you know what, these are wrong practices.

In the car, the distance between people and the air conditioner is closer. If the temperature is too low for a long time, it may lead to arthritis, frozen shoulder, heat cold and other diseases. Moreover, most cars are airtight when the air conditioner is turned on, and the air circulation is not very good. The air conditioner itself also emits some harmful gases. If you stay in such an environment for a long time, you will naturally become sick. Generally, it is more appropriate to maintain a 10-degree difference between the temperature inside the car and the temperature outside the car.

Question 8: Turn on the air conditioner at more than ten degrees, beat him up and promise to change

Question 9: What is the best degree of cold air to turn on the air conditioner? Generally, 27 degrees indoors is best.

Judging from the summer air conditioner start-up index, 30-33℃ is level 4, and 70% of people need to turn it on; 33-35℃ is level 5, and 90% of people need to turn it on. After turning on the air conditioner, pay attention to adjusting the indoor and outdoor temperature difference. The room temperature should be set at about 24℃-18℃, and the indoor and outdoor temperature difference should not exceed 7℃.

If the outdoor temperature is 32 degrees, the indoor air conditioner is generally 25 degrees.

In addition, the air conditioner should not be used for too long. If possible, it is best to open the windows frequently to ventilate, so as to reduce the concentration of harmful gases in the indoor environment and maintain a certain amount of fresh air indoors; if you stay in an air-conditioned room for a long time People who work and live should frequently go outdoors, be exposed to sunlight, breathe fresh air, exercise regularly, pay attention to hydrating the body, and speed up metabolism in the body; air conditioners should be cleaned in time, and if infectious bacteria are found, disinfect them in time.
