Description

A window system that is filtering fine dust of outside air selectively according to external environmental information

The present invention relates to a window system that selectively filters fine dust according to external environmental information, and in more detail, the present invention provides a nanofiber filter formed on a window frame to prevent fine dust contained in external air flowing into a building and Remove the same contaminants.

In addition, through a sensor that automatically detects environmental information of the outside air, the filter is not automatically operated on a day when the outside air is good, and the filter is operated on a day when the outside air is bad, so that the outside air flows into the building. Selectively filter included fine dust.

In addition, the present invention is an invention that not only functions as a window that selectively filters fine dust according to external environmental information, but also can be utilized as a ventilation system of a building by interlocking with an air conditioner or ventilation device of a building.

In the modern society, as technology develops day by day, our lives are becoming more convenient and more prosperous, and many life skills focusing on improving the quality of life compared to the past have been developed and developed.

In particular, among the ways to improve the quality of life in our lives include inhaling clean air. The reason why inhaling clean air is related to the quality of life is air pollution caused by various pollution and air polluted by fine dust. This is because inhalation not only causes headache and dizziness, but also can infect infectious diseases of respiratory tract diseases such as'MERS', which was popular in Korea in early summer 2015 due to various bacteria floating in the air.

In addition, in recent years, serious social problems have arisen due to fine dust from China. If fine dust continues to accumulate in the human body, it adversely affects the bronchi and lungs, leading to respiratory diseases, stroke, myocardial infarction, cardiovascular disease, arteriosclerosis, hypertension It will develop into the same disease.

Therefore, for a healthy and safe life, we need to inhale clean air without fine dust. In reality, it is impossible to remove all fine dust contained in the outside air, so it is included in the external air flowing from the outside of the building to the inside. It is necessary to remove the fine dust.

On the other hand, fine dust is classified into fine dust less than 10 microns (PM10) and ultra fine dust less than 2.5 microns (PM2.5) depending on the size, and ultrafine dust is particularly harmful to the human body than fine dust. It cannot remove ultrafine dust and must use a HEPA filter (High Efficiency Particulate Air Filter) or a nano fiber filter.

The following are prior art related to this.

Here, the window system 10 of the present invention automatically detects the environmental information of the outside air, through the detection unit 400, does not automatically operate the filter on the day when the outside air is bad, Since the operation selectively filters pollutants contained in the external air flowing into the building 20, indoor air flowing into the building 20 can be comfortably maintained.

In this case, the present invention focuses on detecting and removing fine dust among various kinds of pollutants contained in the air, thereby maintaining comfortable indoor air flowing into the building 20.

In particular, the filter 210 applied to the present invention is a nanofiber filter of ultra-microfiber of 100 nm or less, and since ferroelectricity and triboelectric charging method are applied when the filter is manufactured, not only general pollutants contained in the air but also PM1 ultra-fine dust of 1 micron or less Even can be removed. It is possible to manufacture the filter so that its performance is higher than HEPA (High Efficiency Particulate Air Filter), but if the pressure loss of the filter is high, the natural ventilation efficiency decreases sharply. It is manufactured to be 80% level (natural ventilation pressure loss less than 20Pa). Therefore, the window-type filter primarily aims to remove ultrafine dust contained in the air when outside air is introduced in the process of discharging indoor air deteriorated by radon or the like. More than 90% of fine dust removal is achieved in conjunction with air conditioners and air purifiers. The filter is ferroelectric and triboelectric, so it shows superior filter performance compared to existing filters (HEPA or ULPA) at the same fiber density.
