How many degrees of winter air conditioning open appropriate
April 30, 2023
The winter in the north, people generally rely on heating, floor heating, electric heating and other equipment to warm up for the winter, while for the south, most still use air conditioning to heat insulation. Many people may mistakenly think that the air conditioning is certainly the higher the more comfortable in winter, the lower the more comfortable in summer. In fact, this is not right. Open the wrong not only the human body will not be comfortable, the air conditioner also has damage. So, how much is the right degree to open the air conditioning in winter?
How many degrees of winter air conditioning is appropriate
The reasonable temperature of the air-conditioned room in winter is 18 ℃ to 20 ℃ this range. Of course, the national regulations winter air conditioning heating set temperature is not higher than 20 ℃, in order to save energy. Set the temperature of each lower one degree, the national electricity savings of billions of degrees. General household settings are not higher than 18 ~ 20 ℃, in order to health. Set the temperature for each lower degree, the health index increased by 10%. How to set the winter air conditioning temperature is reasonable
Consider from the human comfort point of view
In terms of temperature, the temperature that makes people neither feel hot nor cold is called "physiological zero". Physiological zero is the temperature at which people feel most comfortable. Different people will have different physiological zero degrees. For the general health of normal people, physiological zero is about 28 ℃ to 29 ℃. Therefore, the temperature of the air conditioning room should be selected as far as possible in the vicinity of this temperature. Consider from the perspective of health
Stay in the air-conditioned room to be conducive to health, the key is that the temperature difference between indoor and outdoor can not be too large, generally in 5 ℃ ~ 10 ℃ is appropriate. If the temperature difference is too large, so that people in and out of the sudden change in temperature, easy to suffer from colds and other diseases. Consider from the perspective of favorable power saving
Moderate indoor temperature is not only good for health, but also to avoid overloading the air conditioner. Refrigeration when the temperature is set too low or heating when the temperature is set too high, are more energy-consuming. When heating, just turn on the machine with a low wind gear, half an hour later change to medium wind gear. For friends who like to adjust the indoor temperature, be sure to pay attention to the temperature in winter will not be located in the air conditioning can withstand the extreme 30 ℃, otherwise it will cause frequent start or not stop the air conditioning, increase power consumption, and in serious cases, even damage the air conditioning compressor. As the warm air flow is lighter than air, it is easy to float above the entire closed house, when using wall-mounted air conditioners, it is best to adjust the air outlet to a downward angle, which can save electricity. Even from power saving considerations, the room temperature should not be set too low in the summer, and the temperature should not be set too high in the winter. Notes on the use of air conditioning in winter
Pay attention to more ventilation
When the air conditioner is closed, it will lead to a lack of oxygen in the room over time, and bacteria and viruses will take advantage of the opportunity to accumulate in large numbers. The practice of opening windows for air conditioning is very beneficial to human health, and it does not cost much electricity. You can open the windows a little bit (5~10cm) to let fresh air enter the room continuously. Open the windows for 10 minutes every 2 hours for a change of fresh air.
In addition, if there is a smoking situation, you also need to extend the time to change the air. It is best to open the window of the air-conditioned room and the exhaust fan of the opposite room at the same time, so that the air forced convection for ventilation, the time is 5 minutes. Do not rely on air conditioning
For people who have been staying in air-conditioned rooms, the air does not circulate, the oxygen content is not as good as the outdoor air, a cold and a hot, the elderly and children are particularly vulnerable to colds or respiratory diseases. In addition, the winter air conditioning will cause rapid changes in indoor temperature and humidity, for furniture, especially solid wood furniture is particularly affected. Solid wood furniture is easy to deformation and cracking in this environment. Indoor and outdoor temperature difference should not be too large
It is best to keep the indoor than outdoor 8 degrees Celsius. If the temperature difference between indoor and outdoor is too large, people in the sudden cold and hot environment, easy to catch a cold. For the elderly and people suffering from high blood pressure, the temperature difference between indoor and outdoor should not be too large. Because the indoor temperature is too high, the human body vascular diastole, and then if suddenly to the outdoors, vascular contraction, will make the elderly and hypertensive patients with cerebral blood circulation disorders, very easy to induce a stroke. Winter use of air conditioning beware of "air conditioning killer"
According to the test, indoor air bacteria, viruses in addition to the outdoor air and the activities of the personnel themselves, there is a source that should not be ignored is the ventilation and air conditioning system itself. Cold winter, the use of warm air conditioning units, families, and air conditioning systems in the dirt and suitable temperature and humidity is the ideal place for bacteria, viruses breeding and reproduction, and poor filtration of the air conditioning system will intensify the spread of pollutants and diffusion. According to reports, indoor air pollutants can be divided into 3 categories of respirable particulate matter, biologically active particle pollutants and gaseous chemical pollutants. Respirable particulate matter, also known as "floating dust", can be suspended for a long time and easy to be inhaled by the human respiratory system, in addition to carrying bacteria, viruses and other biologically active pollutants, or a variety of carcinogenic chemical pollutants and radioactive substances, the main carrier; biologically active particles are bacteria, viruses, pollen, etc., airborne bacteria, viruses are most respiratory Infectious diseases and allergic diseases; gaseous chemical pollutants in the air include a variety of volatile organic compounds and inorganic substances, volatile organic compounds are common toluene, formaldehyde, benzene and a variety of hydrocarbons, esters, ketones and other substances. Therefore, in fact, air conditioning is not one of the most scientific way of heating, the principle of air conditioning determines the inadequacy of air conditioning in heating. In fact, home independent heating systems are more energy efficient and more comfortable and healthy. Of course, at present, air conditioning is the most important way to heat the home, winter air conditioning is used properly, and the temperature is set right on the line, not only can save money, but also conducive to health.
