It is often said that water is the source of life. However, as air pollution becomes more and more serious, people realize that the air is the root of human existence and is more important than water.
It is precisely for this reason that when the haze is raging, people's voice for 'good air' is getting louder. So what kind of air can be considered good air?
'Good air' First is clean air
The latest global air quality database published by the World Health Organization in Geneva, Switzerland, on 2 May showed that 9 out of every 10 people in the world breathe highly contaminated air, and annual indoor and outdoor air pollution causes about 7 million deaths worldwide.
Among them, 570,000 children under the age of five die each year from respiratory infections such as pneumonia caused by indoor and outdoor air pollution and second-hand smoke, and one-fourth of adult heart patients die of air pollution.
Dirty air particulate matter (PM10 and PM2.5), bacteria, viruses and other pollutants can easily enter the human lung and cardiovascular system, leading to various respiratory diseases such as bronchitis and asthma, and seriously threatening human health.
According to a survey, an adult who breathes more than 20,000 breaths a day, inhales about 20 kilograms of air, which is 10 times more than the amount of food and water consumed in a day. If you breathe in a polluted air environment, the harm can be imagined. 'Good air' First is clean air without harmful substances to the human body.
Second, 'good air' is a comfortable air
In addition to harmful substances, the air conditioner's temperature, humidity and other factors affect people's health at the same time, determine the degree of human comfort. Air temperature is too high or too low will cause varying degrees of damage to the human body.
Excessive air humidity affects the human body's water discharge. In the summer, heat stroke and other problems may occur. Once the air humidity exceeds 80%, it will increase the risk of rheumatism, kidney disease and other diseases. In rooms with long-term use of ordinary air-conditioning, due to air If the humidity is too low, it will have an adverse effect on the mucous membranes in the eyes, nose, etc., resulting in mucous membrane disease.
People urgently need a 'constant temperature, constant humidity, constant oxygen, constant net' indoor air comfort environment.
For this reason, Haier Air-conditioner not only introduced innovative products such as self-cleaning air-conditioners, it also released the industry's first air-conditioned human body thermal comfort evaluation standard, creating a comfortable and clean healthy air environment.
The Qingdao Healthy Air Research Center was also established on May 23rd. It cooperated with the Geneva Air Research Center of Switzerland and the Air Research Center of New Zealand to continue research and exploration in the field of healthy air. It provided relief and prevention of indoor air pollution damage to human health. Technical and theoretical support.
