Air humidity 70 is dry or wet

Dry. Relative humidity.

The upper limit value should not exceed 80 and the lower limit value should not be less than 30. Not very humid in the range, the most pleasant indoor temperature and humidity are: 18 to 25 and 30 humidity. Air humidity.

The 40-60 is the appropriate environmental humidity for people, which is beneficial to human health. And the environment of 50 to 60 is the most comfortable. Any data above is considered dry. <

Dry. The upper limit of relative humidity should not exceed 80 and the lower limit should not be less than 30. Not very humid in the range, the most pleasant indoor temperature and humidity is:

The temperature is 18 to 25 and the humidity is 30. Air humidity in 40 60 is the appropriate environmental humidity for people, which is beneficial to human health. And the environment of 50 to 60 is the most comfortable.

Any data above is considered dry.

Relative humidity 50 70 is appropriate, too low humidity is easy to cause mucous membranes, **, hoof nails and other infections caused by cracking, too high humidity, easy to cause bacteria and parasites. Cause.

The air humidity is 70% and generally wet.

Normally, the humidity in the room should not exceed 65%, while the humidity at 30% should be relatively dry.

Therefore, 70% air humidity can be considered relatively humid.

It is important to note that everyone may feel differently, and some may prefer a dry environment, while others may prefer a relatively humid environment. Therefore, the perception of air humidity may vary from person to person.

The air humidity is according to China's indoor air standards, and the indoor humidity is 40% to 80% dry in summer, and should be controlled at 30% to 60% in winter. The suitable indoor humidity for the elderly and children is 45% to 50%, and the suitable indoor humidity for patients with respiratory diseases such as asthma is between 40% and 50%.

In southern China, the outdoor humidity is heavy on rainy days in summer, so the window opening time should be reduced; When the weather is fine, open more windows for ventilation and moisture; You can put some moisture absorbent boxes or desiccant in the wardrobe and cupboard. In the north, the air is dry in winter, so you can use a humidifier, sprinkle some water indoors or mop the floor twice a day.

Air humidity less than 30% is considered dry, the drier the air, the more likely it is to generate static electricity, and the relative humidity (RH) has a direct impact on the performance of surface charge accumulation. The higher the relative humidity, the shorter the amount of time the object can store charge, and the way the surface charge decreases (because the relative humidity increases) can be recombined or conducted, and as the relative humidity increases, the conductivity of the air also increases.

Relative humidity less than 30% is considered dry. Usually the environment is below 40%, and it will be relatively dry. The less water vapor is contained in a certain volume of air at a certain temperature, the drier the air; The more moisture, the more humid the air. The degree of wetness and dryness of the air is called "humidity".

The most pleasant indoor temperature and humidity are:

1. The temperature in winter is 20 to 25, and the relative humidity is 30% to 80%.

2. In summer, the temperature is 23 to 30, and the relative humidity is 30% to 60%.

3. In an air-conditioned room, people will feel most comfortable when the room temperature is 20 to 25 and the humidity is 40% to 50%.

4. The room temperature with high work efficiency: 20, the relative humidity should be 40% to 60%, at this time, people's mental state is good, and thinking is the most agile.

This is divided into regions, Beijing, the humidity of the air is about 12%, Shanghai is about 15%, Lanzhou is about 9%, less than 40% is wet, 60% is humid. It's not the same everywhere. Different regions have different regulations, usually the environment below 40% will be relatively dry, most of the items are suitable for storage, more than 60% is relatively humid.

A healthy humidity environment is 45% to 65%, and under such humidity conditions, the human body feels the most comfortable, and various averages are not easy to spread. When the air humidity is lower than 40%, it can slow down the movement of cilia on the mucous membranes of the lungs and respiratory tract, and dust, bacteria, etc. are easy to adhere to the mucous membranes, causing thirst, thirst, hoarseness and sore throat.

Winter temperatures are 20 to 25 degrees, relative to thirty to eighty percent, and in summer 23 30 percent'The relative temperature is thirty to sixty percent. In an air-conditioned room with a temperature of 20 to 25 degrees and a humidity of forty to fifty percent, people will feel most comfortable. The room temperature of 20 degrees with high work efficiency and the relative humidity should be 40 to 60 percent, and the person's mental state is good and the thinking is quick.

The air temperature is more or less dry, and the humidity of the air is more than 50% or less.

Memory is the possession of the past, the capital of today, and the reverie of tomorrow. I haven't forgotten the old love, it's the primary color; Not remembering past grudges is the realm of life. Memory is not for better hate, stacking on the right side of the hand.

Humidity 70% means that under certain temperature conditions, the moisture content in the air is 70%, and 70% humidity indicates that the air humidity is high and measures need to be taken to dehumidify. The higher the humidity, the more moisture in the air and the more humid, the smaller the humidity, the smaller the moisture content in the air, the drier. The following is a detailed introduction to the concept of 70% humidity.

1. Humidity below 70% is the comfortable humidity of the human body, and humidity is a physical quantity that indicates the degree of dryness of the atmosphere, usually expressed as a percentage.

2. The humidity is 70% and humid, and the indoor humidity is generally controlled between 35% and 65%, which can be dehumidified with air conditioners, fans, desiccant, etc.

3. Humidity generally refers to air humidity in meteorology, which can be measured by coulomb hygrometer, optical hygrometer, and ion crystal condensation hygrometer.

4. Humidity is an important data that determines evaporation and transpiration in the meteorology and hydrology, and the possibility of rainfall and fog can be reflected in the weather forecast.

By reading the above, I believe you already know what the concept of humidity 70% is, humidity 70% refers to the moisture content in the air is 70%, and the humidity at home 70 is wet, people will feel stuffy, listless, languishing, irritable, and too low humidity will make people's ** dry.
