Household air system to be encouraged to promote many people are now talking about the air quality, and to improve air quality air system has become a hot topic of people, why home to install a new air system it? The main reason is that modern architecture is getting better airtight doors and windows, indoor air circulation with the outside world is difficult, a long time can cause a serious decline in the quality of indoor air. First, indoor harmful gas can not be discharged. These harmful gases include: the decoration materials such as formaldehyde and benzene, secondhand smoke, infectious viruses and bacteria, which are harmful to human health, in severe cases can cause lung cancer and leukemia. With humans and other expendable Jinxiang indoor ventilation equipment, indoor carbon dioxide concentration, oxygen content is relatively low, people long to live in such a hypoxic environment, can cause headaches, nausea, human premature aging, and heart disease . Thus Shandong indoor ventilation equipment, indoor air quality directly affects our quality of life, while ventilation is to improve indoor air quality in the most direct and effective way to improve the living environment has become and improve quality of life means necessary. In some European countries have put residential ventilation requirements for provision enforceable. The new air system is in this environment came into being. Fog and haze ultimately helper: fresh air system the past five years, global air quality are declining, more and more fog and haze, PM2.5 continued headlines. What is the PM2.5? Create a healthy and comfortable home life single county indoor ventilation equipment, air system can not be separated. As the name suggests, PM2.5 refers to the diameter of the atmosphere is less than or equal to 2.5 micron particles, also known as particulate matter into the lungs. Its diameter is less than 1/20 of the thickness of a human hair, can be deep into our lungs and even the blood through the respiratory tract. PM2.5 small particle size, surface area, active, easy incidental toxic and hazardous substances (eg, heavy metals, microorganisms, etc.), long residence time in the atmosphere, transmission distance, a huge impact on human health and environmental quality of the atmosphere . Experts advise, fog and haze minimize out, do not open the windows. Many people on the speech, the day is not windows, interior how bad environment to ensure that ?? Do not worry, experts also found that the concentration of PM2.5 in the fresh air, low, low hazard. Therefore, an effective way to improve indoor air quality is to make indoor ventilation, always ensure fresh air to enter. Townsend fresh air system, by continuously uniformly fresh air into the room (ordered ventilation), to add enough fresh indoor air (ie oxygen), while the polluted indoor air through heat recovery (energy) back to the outside. Fresh air through the filter (filter dust) and then into efficient heat recovery, and then into the room. Through the heat recovery, into the interior of the fresh air temperature close to room temperature, somatosensory comfortable.
