1. As far as comfort is concerned, the main purpose of turning on the air conditioner is to make people feel more comfortable, neither too cold nor too hot. This temperature is also called "physiological zero". For healthy people, physiological zero is generally 28℃, so the temperature of air conditioner should be around this temperature.
2. As far as health is concerned, the temperature difference between indoor and outdoor is best controlled within 10℃ ... because when we are indoors, if the temperature is too high, our pores will open. When the outdoor temperature suddenly turns cold, the temperature control center has no time to react, and it is easy to catch a cold.
3. As far as power saving is concerned, if the air conditioner is lowered by 2℃, it will save more than 10%. From the point of view of energy saving, of course, the lower the temperature, the more energy saving.
4. The optimal temperature of air conditioning in winter is 20℃. Moderate indoor temperature is not only beneficial to health, but also can avoid air conditioning overload. When heating, use the low windshield at first and the medium windshield after half an hour.
5. For friends who like to raise the indoor temperature, please be careful not to set the temperature at the limit of 30℃ that the air conditioner can bear in winter, otherwise it will cause the air conditioner to start or not stop frequently, increase the power consumption, and even damage the air conditioner compressor in serious cases.
Because the heat flow is lighter than air, it is easy to float on the whole closed room. When using a wall-mounted air conditioner, it is best to adjust the air outlet to a downward angle, which can save electricity.
To sum up, the air conditioning temperature must be set within a reasonable temperature range, that is, 26℃ ~ 28℃ in summer and 18℃ ~ 20℃ in winter. The air conditioning temperature should not be too different between indoor and outdoor, and it is generally appropriate to be between 5℃ and 10℃. In addition, because the heating flow is lighter than air, it is easy to float on the whole closed room. When using a wall-mounted air conditioner, it is best to adjust the air outlet to a downward angle, which can save electricity.
Just turn on the air conditioner below a few degrees in winter. If there are old people and children at home, in order to avoid catching a cold, you can consider turning on the air conditioner when the outdoor temperature in the south is lower than 15℃.
Don't turn on the air conditioner often in winter. It's better to start the machine after 2 hours, which is more conducive to human health. How to prevent air-conditioning diseases in winter?
1 Air-conditioned rooms should be ventilated regularly, and the windows should be opened at least 2 to 3 times a day for half an hour each time, which can reduce the chances of indoor bacteria breeding. Besides, if you stay in the air-conditioned room for too long, you can go out for air.
2. Clean the air conditioner regularly. When the air conditioner is turned on, bacteria will be blown into the air and enter the human body, causing various diseases. Therefore, it is very necessary to clean and maintain the air conditioner regularly.
3, pay attention to the body hydration
A person needs to drink 1.5-2 liters of water every day in order not to be short of water in a warm room. In addition to drinking water every day, choose some fruits and vegetables and salty soup porridge, which has a good hydrating effect. In addition, in order to prevent "
Air conditioning disease ",you can eat more warm food, such as sesame, radish, tomato, tofu, tremella and so on."
4. Control indoor humidity Because of the use of air conditioning for heating, the room is usually dry. In order to control indoor humidity, most people like to use humidifiers. It should be noted here that,
Don't add tap water directly to the humidifier, it's better to add pure water, or boil tap water and wait until it cools to about 30℃ before adding it. In addition to humidifying with a humidifier, it is best to raise more green plants, such as
Cactus plants But indoor plants should not be too many, usually one or two pots in a room. How many degrees does the air conditioner turn on in winter? It is best to set the air conditioning temperature at around 20℃ in winter, and families with old people and children can adjust it to around 25℃ appropriately.
We know how appropriate it is to turn on the air conditioner in winter, so let's learn about the precautions for turning on the air conditioner in winter. Matters needing attention in turning on air conditioning in winter
1, the temperature is not too high. The air conditioning temperature should not be too high in winter. It is better to keep the indoor air conditioning temperature at 25 to 26 degrees Celsius, because people are prone to catch a cold in an environment with excessive indoor and outdoor temperature difference. In addition, the air in the air-conditioned room is dry and dusty, which is easy to cause dry nose and mouth. For patients with respiratory diseases such as asthma and pharyngitis, more attention should be paid to rational use.
Secondly, the most important thing is to use a vacuum cleaner to remove the dust from the indoor fan before use. Open the window and ventilate for a few minutes while turning on the computer every day. When it is used for the first time, it should be ventilated for a period of time, so that the bacteria, molds and mites accumulated in the air conditioner can be distributed as much as possible. Air conditioning filters should also be disinfected frequently. Don't turn on the air conditioner indoors for too long.
2. Prepare a bottle of moisturizing spray. The moisturizing spray added with hyaluronic acid, aloe essence and rose water will last longer. Spray moisturizing spray on the skin every 2 hours.
Then pat it with your fingertips to make it better absorbed by the skin through a slight temperature. At the same time, you can prepare a basic skin care product in the office. Every day at noon or when the skin feels dry, you can wash off the floating dust on your face or press it with a wet towel, and add moisturizing lotion, moisturizing cream and sunscreen products. If you are going to work overtime at night, you should add a "moisturizing light meal" during the day. In addition to paying attention to the moisturizing work of facial skin, don't forget that hands, feet, lips and other body skin are often exposed, and remember to spray body moisturizing spray or lip balm regularly.
3, put the humidifier If the room temperature is not very high, it is best not to turn on the air conditioner, so as not to accelerate the evaporation of water in the human body. Don't forget to turn on the humidifier while turning on the air conditioner, so as to ensure proper air humidity and alleviate the problems such as excessive dehydration of skin and dry throat caused by local air drying. The humidifier doesn't have to be on all the time.
In general, when the room temperature is 25℃, the relative humidity of the air environment should be controlled at 40% ~ 50%.
4. People who work and study in air-conditioned environment for a long time will have symptoms such as nasal congestion, dizziness, sneezing, tinnitus, fatigue, memory loss, and some skin allergies, such as tight and dry skin, allergies, and skin deterioration. These conditions are related to long-term indoor ventilation.
Because the human body is very sensitive to temperature and air humidity, ventilation can not only dilute harmful gases, but also restore the environment to a certain humidity and gradually restore the self-regulation function of the human body. In a small space (about10m2), it is generally recognized that the best ventilation period is about two hours. If you can breathe 15 minutes in two hours, you can keep the indoor air fresh without increasing too much power consumption.
5. Adding water to dry is actually losing water. To prevent dryness, of course, it is necessary to replenish water, and the simplest and most convenient way to replenish water is to drink water. However, drinking water in winter is very particular. Drink a small amount of water many times, both sweet and salty. Because adding a small amount of salt to drinking water can reduce the loss of water in the body and maintain the metabolic balance of water and salt in the body, while light sugar water or honey water can moisten the lungs and nourish yin. So there is "
The way to keep healthy drinking water is "salt water, honey at night".
Next, let's take a look at some precautions for car air conditioning in winter. Car air conditioners need special maintenance in winter: be careful of your air conditioner strike.
Don't think that car air conditioners will only be used in summer. In fact, it is the same in winter, and the frequency of car air conditioners is also very high. In the cold winter, many people have the habit of turning on the heating as soon as they get on the bus; When it rains, the window glass fogs, and the easiest way is to turn on the air conditioner to eliminate it. There are many tips on how to use air conditioners correctly.
1. Clean the air filter frequently, usually once every two or three weeks: clean the air-conditioning filter frequently and replace it regularly to maintain good air-conditioning quality.
Generally, the air-conditioning filter element should be cleaned every 5,000 kilometers or 3 months (whichever comes first), and the air-conditioning filter element should be replaced every 20,000 kilometers or 12 months (whichever comes first).
2. Protect the heat sink of condenser and evaporator: The heat sink of condenser and evaporator is made of 0. 15mm aluminum sheet inserted into copper tube and expanded, which cannot withstand collision. If the heat sink is damaged, it will affect the cooling effect of the air conditioner;
Clean the condenser frequently. After driving in the rain or muddy road, check whether there are deposits and stones on the condenser fan, and clean them up in time if there are. Some car owners often flush the condenser with water pipes when using air conditioners in summer, which is quite correct. Because the cleaning of automobile condenser surface is easy to radiate heat energy, cleaning the condenser surface regularly can greatly improve the refrigeration effect of air conditioning system.
3. Protect the refrigeration system: if the components or connecting pipes of the refrigeration system are damaged, the refrigerant will leak, resulting in the inability of the air conditioner to cool; Correct selection of fuse. by-product
The specification of the fuse is selected by the rated current indicated in the manual. If it is too big, it will not play a safe role. If it is too small, it will often fuse.
4, air conditioning manual stop and start operation time should be more than 2 minutes, can't stop and start continuously.
5. Prevent the electrical system from being affected with damp: the electrical system is prone to leakage after being affected with damp. Therefore, water should not enter the electrical system, especially in rainy season.
6. Pay attention to the operating sound of the air conditioner: if you hear abnormal noise during the operation of the air conditioner, such as metal collision sound, motor buzzing sound, shell vibration sound, etc. , you should shut down the machine immediately and check the reason.
