What is humidity?
Humidity refers to the dry humidity of water vapor in the air. Relative humidity refers to the percentage of the vapor pressure in the air compared to the saturated vapor pressure at the same temperature. When the relative humidity in a place is too high or too low, it can lead to environmental health problems, and even affect people's physical and mental health.
Humidity, commonly referred to in meteorology, refers to air humidity, which is the content of water vapor in the air. Liquid or solid water in the air is not counted as humidity. Air that does not contain water vapor is called dry air. Since water vapor in the atmosphere can account for 0% to 4% of the volume of air, when listing the composition of various gases in the air, it refers to the composition of these components in dry air.
The degree of dryness or wetness of air, or a physical quantity indicating the amount of water vapor contained, is called humidity. The mass of water vapor contained in unit volume of air is called absolute humidity. Due to the difficulty of directly measuring the density of water vapor, it is usually expressed by the pressure of water vapor. The absolute humidity of the air does not determine the speed of water vapor on the ground or a person's perception of the degree of humidity. People refer to the absolute humidity of air at a certain temperature and the percentage of saturated air pressure at the same temperature as relative humidity.
Why is indoor air quality important?
Most people may spend 90% of their time indoors, whether it's living or working. Without open windows or ventilation, they always breathe the air that others or themselves breathe.
Low air quality has a considerable ripple effect on people's health and work efficiency. For example, pollutants in the indoor environment (such as high concentrations of carbon dioxide) can lead to chronic diseases, and low humidity can lead to dry eyes and sore throat. In general, low air quality can lead to headaches, physical fatigue, respiratory problems, and inattention. From a work perspective, the labor force's absenteeism rate will be higher, and when they work in this environment, their productivity level will also decline. This study has shown time and again the links between air quality, work performance, and healthy living.Work efficiently and live a healthy life. Everyone needs a healthy and comfortable environment. In daily life or work, low air quality is largely related to the humidity of the surrounding air.
According to research by physiologists, the comfort of the human body is the result of two factors: temperature and humidity. While paying attention to temperature, it is also necessary to adjust indoor humidity. In summer, when indoor humidity is too high, it can inhibit human body heat dissipation, making people feel sultry and irritable; In winter, when indoor humidity is too high, it can accelerate heat conduction, making people feel cold and depressed. When the indoor humidity is too low, a large amount of water in the mucous membrane of the upper respiratory tract is lost, and people may feel dry mouth and easily catch a cold. Experts believe that the upper limit of relative humidity should not exceed 80% RH and the lower limit should not be lower than 30% RH. According to experimental measurements, the most pleasant indoor temperature and humidity are: 18 ℃ to 25 ℃ in winter, and 30% RH to 80% RH in humidity; In summer, the temperature ranges from 23 ℃ to 28 ℃, and the humidity ranges from 30% RH to 60% RH. Most people feel comfortable within this range.
Methods for improving air quality.
Low air quality is a relatively serious problem in China, and improving air quality is very important. One of the breakthroughs in ensuring high-quality indoor air is to control air humidity and purify air. Methods for improving indoor air quality:
(1) Open the window and let the air circulate. This also reduces indoor moisture and odor, especially in the kitchen.
(2) Regularly replace the air filter to ensure effective purification of the air circulation.
(3) Add indoor plants. Plants are biological air purifiers that have been proven to improve indoor air quality
(4) Install a fresh air dehumidification system. Humidity control is the biggest factor affecting indoor air quality. The installation of the fresh air dehumidification system effectively ensures that the indoor air environment is maintained at a comfortable level.
