How to avoid dry climate indoors in winter?

It's winter. In order to make the citizens spend the winter safely and comfortably, we will launch the "Winter Life Series Reminder" from today to make suggestions for your winter life. Tianjin will officially enter the heating season tomorrow. Today, we will first introduce how to use heating equipment safely. In the future, we will also pay all-round attention to your clothing, food, housing and transportation in winter and provide all-round services.

Ventilation is as important as moisturizing.

In winter, people tend to be most concerned about indoor temperature, but less concerned about indoor air humidity. In fact, if the room temperature is too high and the humidity is too low, people will feel uncomfortable, and even chapped lips, nostril bleeding, and dry throat will appear. When the air is dry, the reproduction speed of influenza virus and gram-positive bacteria that can cause infection is accelerated, and it is also easy to spread with dust in the air, causing diseases. For families that have been heated, the most important thing is to pay attention to indoor moisturizing. If the relative humidity is low, you can sprinkle some water on the ground or mop the floor with a wet mop to increase the humidity. You can also put a basin of water near the cooling facilities to let the water evaporate slowly and keep the indoor air moist. In addition, if you keep a few pots of flowers and plants in the room, you can not only adjust the indoor relative humidity, but also make the room full of greenery. Families with humidifiers should pay attention to adjusting indoor humidity regularly in order to fully serve their health.

Due to the cold weather in winter, doors and windows are closed in general life and workplace. At this time, the best air disinfection method is to open the window for ventilation. According to reports, a normal person breathes 16- 18 times per minute, and carbon dioxide in exhaled gas accounts for 4%. In addition, air itself contains a certain amount of carbon dioxide. If the total indoor carbon dioxide content reaches 5%, people will suffocate. Therefore, families with closed doors and windows have a special smell indoors, which is a manifestation of insufficient indoor oxygen. When the temperature difference between indoor and outdoor is 20℃, it takes 9 minutes for an 80 cubic meter room to be completely ventilated. If the indoor and outdoor temperature difference is 15℃, the window opening time needs 1 1 min; If you can't accurately grasp the temperature difference, it is enough to open the window for 30 minutes. The best window opening time is 9: 00 am-11:00 or 2:00-4:00 pm. Because of the temperature rise in these two periods, the harmful gases deposited in the bottom of the atmosphere have dispersed, and the ventilation effect of window opening is better.

Use floor heating and coal stoves to prevent poisoning.

At present, there are still a few residents in this city who are not included in central heating. Xinbao especially reminds residents who use coal fire for heating that when installing chimneys, they must pay attention to installing T-shaped smoke outlets with two-way openings, because such devices can effectively avoid smoke back caused by outdoor strong winds and prevent gas poisoning. In addition, it is also important to ensure indoor ventilation at any time. At the initial stage of soot poisoning, people usually have symptoms such as dizziness, headache, nausea and vomiting. Once such symptoms appear, you should leave the toxic environment in time and go to the hospital for treatment immediately. In addition, the elderly are also the main targets of carbon monoxide poisoning, so the elderly should pay special attention to heating safety in winter.

It is best to use less air conditioners and electric heaters.

With the coming of winter, the use of electric heaters and blankets has become the main heating measure for some residents. Xinbao reminds the public that while enjoying the convenience of high-power heating equipment, don't forget to use electricity safely. Especially remember to turn off the power before going to work to prevent accidents. In addition, in the process of fire fighting, citizens should cut off the power supply to prevent electric shock if they find that electrical appliances are on fire.

It is understood that the current household electricity meter is generally 5- 10 A or10-20 a. To buy heating equipment, we must first calculate whether the total power exceeds when the household appliances are turned on at the same time. If forced to use, it will lead to tripping or fuse blowing. If the total power of household appliances exceeds the capacity of your own electric meter, you must go to the power supply business hall in time to increase the capacity. When using high-power electrical appliances, try to ensure that only one plug is connected to one socket. If there is an air-conditioning line in the room, you can use the air-conditioning line socket directly.

For families who use air conditioners or electric heaters to keep warm, the electricity bill is undoubtedly the key issue. In order to keep the indoor temperature, many families will close the doors and windows when using air conditioning for heating. It is the right temperature that makes germs multiply indoors and be sent to every corner of the room with the circulation of air flow. People who stay in air-conditioned rooms for a long time will feel dizzy and weak, and in severe cases they will suffer from respiratory diseases. Therefore, it is necessary to reduce the use time of air conditioners as much as possible in winter, and open doors and windows for ventilation; Even if the air conditioner needs to be used continuously, leave a gap of 3 to 4 cm in the window to let fresh air in. There is another problem with air conditioning heating. When the temperature is lower than-15℃, it will be very difficult to start. So you can prepare an electric heater, but the problems of air drying and poor heating effect caused by air conditioning heating also exist.

There are tricks to keep warm and save energy.

Heat is a resource and should be used sparingly. For central heating users, at present, the heating facilities in most families are not adjustable in temperature, and some of them are metered heating or equipped with adjustable temperature stalls. If possible, don't set the temperature at home too high. Generally speaking, people feel comfortable between 22℃ and 24℃. If it is above 26℃, they will feel that the temperature difference between indoor and outdoor should be minimized when heating in hot winter. The minimum set heating temperature for residents in this city is 16℃, which is equivalent to the warm water spring in Tianjin. Compared with the outdoor cold season, this temperature has temperature changes and is easily adapted by the human body. If the room temperature is too low, people will easily catch cold, which will induce respiratory system and cardiovascular and cerebrovascular diseases with serious consequences. Therefore, the indoor temperature should not be too low for the elderly with poor resistance and people with chronic diseases such as cardiovascular and cerebrovascular diseases. However, if the indoor temperature is too high and the temperature difference with the outdoor is too large, the body can't adapt, and it is easy to make the heart, lungs and other organs involved.

The cost of heating in winter usually accounts for about 64% of a family's energy consumption, especially in the absence of central heating, it is necessary to ensure comfort and pay attention to saving. To save energy, we must first control the room temperature scientifically. The ideal indoor temperature is 20℃ during the day and 15℃ to 17℃ at night. In addition, turn off the radiators in those rooms that are not commonly used and close the doors of those rooms. Double-glazed windows can save energy by 20%, and if curtains are thickened on doors and windows, energy can be saved by 5% to 10%.
