Description

Air conditioner with function of fine dust removal

The present invention relates to an air conditioner having a function of removing fine dust, and more specifically, air having a function of removing fine dust to remove fine dust, facilitate filter maintenance, and remove moisture to save energy. It's about harmony.

The air conditioner keeps the indoor air in a comfortable state, and adjusts a certain space to a temperature, humidity, and airflow distribution suitable for human activities, and at the same time, removes dust in the air. The air conditioner cools the room by blowing low-temperature wind in the summer and blows warm wind in the winter so as to be heated. In addition, in recent years, air conditioners have been expanding the requirements of occupants to indoor air quality and comfort, and thus various systems such as ventilation systems and dehumidifying devices have been introduced.

1 is a view illustrating a conventional air conditioner. Referring to Figure 1, the conventional air conditioner is a return unit (RA) through which the air returned from the use is introduced, an exhaust unit (EA) through which the air flowing through the return unit (RA) is discharged to the outside, and outside air is introduced Ventilation chamber (C1) to form the flow path connecting the outside air (OA), the air supply (SA) for discharging the temperature and humidity controlled air to the user, and the return section (RA) and the exhaust (EA) ), and includes a housing 10 that forms a flow path connecting the outer air portion (OA) and the air supply portion (SA) and has a supply chamber (C2) partitioned by a ventilation chamber (C1) and a partition wall (11). do. And inside the enclosure 10 includes a first blowing fan 12, a second blowing fan 13, a filter 14, a cooling coil 15, a heating coil 16 and a total heat exchanger (17). Such a conventional air conditioner automatically adjusts the flow rate of exhaust air through the exhaust unit EA and the inflow amount of outside air through the outer air unit OA according to the temperature of the air returned from the place of use and the temperature of the outside air to enter the air conditioner. The temperature change of the air is minimized, and the first and second blowing fans 12 and 13 are controlled according to the pressure difference between the ventilation chamber C1 and the air supply chamber C2.

Such a conventional air conditioner may be equipped with a filter to filter foreign substances harmful to the human body, such as various dusts floating in the air flowing from the outside, and supply them in a clean and purified state. Such a filter is an initial and medium performance filter, which can remove dust, but cannot remove fine dust having a particle size of 10 µm or less in diameter. Since the fine dust is so small that it is invisible, it stays in the air and can penetrate the lungs, etc. through the respiratory tract or move into the body along the blood vessels and enter the body. In addition, when fine dust enters our body, the cells in charge of immunity act to protect the body by removing dust, and an inflammatory reaction, which is a side effect, appears. When these inflammatory reactions occur in each organ of our body, such as the airways, lungs, cardiovascular, and brain, asthma, respiratory, and cardiovascular diseases can be triggered.

When a high-performance filter that is more than a sea wave filter is used to remove such fine dust, it is difficult to clean, replace, and check the filter, and there is a problem that the use is restricted. In addition, since the sea wave filter increases the static pressure of the blower fan, there is a problem in that the electric power increases and consumes a lot of electric energy.

On the other hand, in order for the filter to function properly, maintenance such as cleaning and replacement must be performed periodically. However, in general, in the case of an air conditioner, there is a problem in that it is often impossible to supply clean air to the room because it is frequently used without regular cleaning and replacement of the filter.

In addition, a lot of energy must be used to remove moisture contained in the outside air, and corrosion of the apparatus due to moisture increases, and thus durability is significantly reduced.
