Is it cold indoors at 20 degrees in northern winter?

In winter, when the dry room temperature is low, it will feel cold, and 24 degrees Celsius is the most comfortable, and in summer, when the humid room temperature is high, it will feel hot, and 22 degrees Celsius is the most comfortable.

The indoor temperature in the northern winter is 17-25 moderate.

The most comfortable temperature for people in winter is 17-22, and when the ambient temperature is below the lower limit of comfortable temperature, people feel cool and cold. If the ambient temperature is below 0, it will feel bitterly cold. People will feel most comfortable in an air-conditioned room with a room temperature of 19-24 and a humidity of 40%-50%.

Ways to increase indoor humidity in the northern winter.

1. First of all, don't throw away the peels of oranges and grapefruits, because the moisture content of these peels is relatively large, and after being placed on the heating, it can also have a certain humidification effect, and it can also exude a fragrant fruit fragrance, and can also indirectly purify the air.

2. Then there is often open the window for ventilation, because the outdoor air humidity is greater than the indoor, generally speaking, the window is opened at about ten o'clock in the morning to change the indoor air flow. Although it is cold in winter, the window should not be opened for ventilation at least twice a day, and each time it should not be less than 15 minutes.

3. It is also a good way to raise more green plants indoors. You're like a cactus-like plant that exhales oxygen at night and freshens the air while making the room feel moist, while large-leaved plants like spider plant and brazilwood evaporate more water from their leaves.

It is not cold, and the national heating standard is a minimum of 16 degrees. 22 degrees is a very warm temperature.

The most pleasant indoor temperature and humidity is 18 degrees Celsius in winter.

to 25 degrees Celsius, humidity from 30 to 80; In summer, the temperature ranges from 23 to 28 degrees Celsius and the humidity ranges from 30 to 60. More than 95 people feel comfortable in this range. In an air-conditioned room, the room temperature is 19 degrees Celsius to 24 degrees Celsius, and the humidity sensor is 40 to 50 degrees Celsius.

It's 20 degrees in the house, and it is necessary for ordinary people to wear sweaters, so that they will not feel cold in the house.

It's not cold, it's definitely cold in short sleeves.

20 degrees in the house, it's certainly not cold, because 20 degrees is also a very high temperature in the spring, you wear short sleeves in the spring, walk around the house at 20 temperatures, you won't feel cold, if it's in the autumn, you'll feel very warm, if it's in the winter, you've just come back from minus a few degrees Celsius outside, and when you get to the house in the 20s, you'll feel warm, and after you sit down for a few minutes, you'll feel sweaty and want to take off your clothes to cool off.

In winter, 22 degrees indoors is not considered cold, because the national heating standard is a minimum of 16 degrees, so 22 degrees is a very warm temperature. The most pleasant indoor temperature and humidity is 18 to 25 degrees Celsius in winter and 23 to 28 degrees Celsius in summer.

In this range, more than 95% of people feel molded oak to comfort.

Comfort temperature refers to the equivalent temperature at which a certain environment meets the comfort requirements under the conditions of a given amount of human activity, clothing thermal resistance and ambient temperature, and is the temperature at which the human body feels comfortable.

There are many factors that affect the comfortable temperature, which vary from person to person, and the main factors include: gender, age and thickness of clothing, activity, environmental conditions and regional characteristics.

According to experiments in China and abroad, the most comfortable temperature for people is 19-24 in summer and 17-22 in winter. When the ambient temperature exceeds the comfort range, people feel hot or cold.

In winter, the maximum daytime temperature in the north can be 0 degrees. Even Beijing, which is relatively warm in the north, has consecutive ice days in winter, and it is common for the maximum temperature to be below 0 degrees for several days. But with heating, everything is different.

In the central and eastern regions, the southern boundary of China's central heating is slightly souther than the Qinling Mountains, and slightly more north than the Huaihe River, just near the north-south dividing line in the geographical sense.

The origin of temperatureThe origin and definition of temperature are: According to the observable phenomenon of a beam closure, such as the expansion of the mercury column, the degree of heat and cold measured according to one of several arbitrary scales of rubber coarseness. Temperature is a manifestation of the average translational kinetic energy between molecules within an object.

The faster the movement of molecules, the hotter the object, i.e., the higher the temperature. The slower the molecular motion, the colder the object, i.e., the lower the temperature. From the point of view of molecular motion theory, temperature is a sign of the average translational kinetic energy of the molecular motion of an object.
