What is the right indoor humidity and temperature in summer?

Hello, through experimental measurements, the most pleasant indoor temperature and humidity are: 18 to 25 in winter, 30% to 80% humidity; In summer, the temperature is 23 to 28 and the humidity is 30 to 60 percent. More than 95% of people feel comfortable in this range.

People will feel most comfortable in an air-conditioned room with a room temperature of 19 to 24 and a humidity of 40 to 50 percent. If the influence of temperature and humidity on people's thinking activities is taken into account, the most suitable room temperature should be high work efficiency. 18. The humidity should be 40% to 60%, at this time, people's mental state is good, and their thinking is the most agile.

According to the requirements of the national indoor air quality standards: the indoor air humidity standard is 30% 60% in winter, the humidity index is 50% 60% The environment is the most comfortable, and the indoor temperature should not be higher than 24 degrees.

Due to the dry air and low humidity in winter, which leads to the breeding and spread of germs, coupled with the use of heating and air conditioning, the humidity in the indoor environment is often low, which is easy to make people nervous, dry and hot, it is recommended to take some effective measures, such as drinking more boiled water; ventilation; Grow greenery to increase indoor humidity.

4% to 8%.

In 23 years, the state issued indoor air standards, and the relative humidity should be 4%-8% when cooling in summer; In winter, heating should be controlled at 3%-6%. The suitable indoor temperature for the elderly and children is 45%-5%; For patients with respiratory diseases such as asthma, the optimal indoor temperature is between 4% and 5%.

Because humidity is difficult to feel concretely, it is recommended to have a hygrometer at home so that you can adjust the humidity at any time.

The average person feels most comfortable at 45-55% relative humidity. In summer, the temperature is high, and humidification should be taken care of.

1. The humidity of the room is 85. In summer, the indoor humidity is generally 40% to 80%, and in winter, the indoor humidity should be controlled at 30% to 60%. If the indoor humidity exceeds 80%, the water vapor content in the air is relatively high, and the heat of the human body cannot be quickly dissipated, which is easy to cause discomfort to the human body.

2. Humidity is a physical quantity that indicates the degree of dryness of the atmosphere, which generally refers to air humidity in meteorology, mainly referring to the content of water vapor in the air.

3. Under suitable temperature conditions, the less water vapor is contained in a certain volume of air, the drier the air, and the more water vapor is contained, the more humid the air is.

4. If the home is damp, you can place a dehumidifier or dehumidifier indoors, or adjust the air conditioner at home to the dehumidification function, which can help the room become dry to a certain extent.

In winter, it is generally recommended that the indoor humidity should be less than 70%.

The humidity that the human body feels comfortable with is less than 70% relative humidity. Theoretically, the humidity that the human body can adapt to is 30%-80%, but the higher the humidity, the more uncomfortable it may be, affected by the weather temperature, it is generally recommended that the indoor humidity should be lower than 70% in winter.

In autumn and winter and in the room with the air conditioner on, the humidity is usually only 10%-15%rh, and the humidity in such a room is too low, and it will make people feel tight, dry and even hot after staying for a long time. Therefore, in winter, we should pay attention to maintaining indoor humidity, especially in the heated room, to ensure that the relative humidity is 45%-65%rh, and the human body feels the most comfortable within this range of humidity.

The harm of dryness to the body.

1. It is easy to cause the spread of bacteria. Dry air is the main cause of the increase in dust and particulate matter, while bacteria cannot exist alone and tend to cling to dust. The elderly and young children have weak body resistance and are susceptible to bacteria and viruses, and warm and dry is the best environment for the breeding and spread of many viruses and bacteria.

2. It is easy to cause excessive loss of body water, infection with diseases, and accelerated aging. In a dry environment, we wake up every morning with a dry mouth, tight muscles, and a depressed mood.

Especially in women, the muscle fibers are composed of a large amount of water-soluble collagen, and the dryness makes the muscle fibers shrink due to rapid water loss, and over time, the muscle fibers may break, and there will be irreparable wrinkles and aging. The reason why southerners are better than northerners is due to the difference in air humidity.

In summer, the humidity of the room should be 40%-80%.

In general, humidity has a certain relationship with temperature, the indoor temperature in summer is generally about 25 degrees Celsius, so the relative humidity between 40%-80% is the most suitable humidity for the human body, once it exceeds this range, it needs to be dehumidified.

The mass of water vapor contained in a unit volume of air is called absolute humidity. Since it is difficult to measure the density of water vapor directly, it is usually expressed as the pressure of water vapor. The absolute humidity of the air does not determine the speed of water vapor above ground and the perception of humidity in people.

The absolute humidity of the air at a certain temperature and the percentage of saturated air pressure at the same temperature are called relative humidity.

When setting the humidity in the air-conditioned room, the relative humidity that is more suitable for the human body is: when the room temperature is 25 in summer, the relative humidity is controlled at 40%-50% and is more comfortable; When the room temperature is 18 in winter, the relative humidity of the rock calendar is controlled at 60%-70%.

The average person feels most comfortable at 45-55% relative humidity. The relative humidity in an overheated and unventilated room is generally low, and too high humidity affects the perspiration function of the person to regulate the body temperature, and the person will feel stuffy.

In general, people feel better in situations of high temperatures but low humidity (such as deserts) than in situations where the temperature is not too high but the humidity is high (such as rainforests). Qingliang.

Air indicators

There are two general air indicators: one is temperature, the other is humidity, dehumidification is to reduce the proportion of water contained in the air, if the temperature is not very high like Huangmei, but the humidity is very high, people feel that the sweat is wet, then another function of the air conditioner appears, it can play a dehumidifying role, and the dry air makes people refreshed.
