Title: What is the principle of dehumidifier humidifier, and which one should be bought for the difference between north and south?)
dehumidification, you can hardly expect dry underwear to wear; Unlike in the south, the winter climate in the north is dry. Remember, during the winter in the north, due to the lack of the habit of using a humidifier, there was not much nasal bleeding at that time
Body comfort range
The size of indoor ambient humidity affects human comfort According to expert research results, the air is too humid. Or being too dry can have an impact on human health. If the humidity is lower than 40%, it will make bacteria and viruses more likely to occur, increasing the incidence of Allergic rhinitis, asthma and other respiratory diseases; If the humidity is higher than 60%, it will promote the growth of molds, mites, and other pests, and also pose a latent hazard to the human body. When the indoor humidity is below 30%, the air is too dry and the body's moisture evaporates too quickly, which can lead to dry respiratory mucosa, sore throat, and thirst. It is very unfavorable for patients undergoing tracheotomy or respiratory tract infection, so the most suitable humidity range is between 40% and 60%
The green area on the Hygrometer, It is a comfortable temperature and humidity range for the human body.
Wet weather can have multiple effects on a person's mood and body The impact can trigger listlessness, irritability, and unease, It can cause adverse reactions such as shortness of breath and chest tightness in the human body, and further exacerbate the pain of arthritis and rheumatism. At the same time, microorganisms such as bacteria, molds, viruses, mites, and other microorganisms can multiply in a humid environment, increasing the risk of disease
Dampness is essential for daily life Health causes all-round hazards
Therefore, Dehumidifier is located in densely populated coastal areas and central cities in eastern and southern China, There is a huge market space and growth rate. The average annual relative humidity in these humid areas ranges from 70% to 80%, and even reaches as high as 95% to 100% in winter and spring, while the temperature is often very low. The wet and cold weather is the right time for the Dehumidifier to exert its skills
Annual Precipitation Distribution Map of China
The Dehumidifier industry should step into a more mature stage to attract more potential consumers, The urgent task is to provide consumers with a standardized and scientific shopping guide to resolve their confusion. At present, the more authoritative standard we can find is the national standard of Dehumidifier issued in 2003 and officially implemented in 2004, which clearly stipulates the basic parameters and technical requirements of Dehumidifier, such as nominal dehumidification capacity, dehumidification capacity per unit input power, maximum load operation, noise, etc
Dehumidification capacity
Because of the working principle of the Dehumidifier, Use a fan to draw moist air into the machine, Let the water molecules in the humid air condense into water droplets under the action of a heat exchanger, and then discharge the treated dry air outside the machine. This cycle keeps the indoor relative humidity within a suitable range. Therefore, the amount of dehumidification is an important index to investigate the Dehumidifier, and the data such as relative humidity, body comfort zone, power, area, and time provide auxiliary reference for us to evaluate the dehumidification effectCurrently, regarding "dehumidification capacity", There are three forms of representation: nominal dehumidification capacity, rated dehumidification capacity, and maximum dehumidification capacity. The rated dehumidification capacity is a commonly used labeling method in the domestic market, which takes a temperature of 30 ℃ and a relative humidity of 80% as the environmental premise, and is expressed in "L/D" units. The dehumidification parameters mentioned in the following text are all rated dehumidification values<
