Description

Air conditioning equipment {AIR CONDITIONING APPARATUS}

The present invention relates to an air conditioner for purifying air.

In order to create comfortable indoor air in living spaces and protect human health, the installation of air filtering devices is continuously increasing. In recent years, it has become almost essential to provide air conditioning functions as well as air purification functions to air conditioners installed in buildings or underground facilities. However, in general, pollutant dusts in human residential spaces and office spaces are distributed in a wide variety from sub-micron units to tens of microns in particle size, and have very different characteristics chemically or microbiologically. Therefore, according to the chemical or microbiological properties of the contaminated dust, the harmfulness of the contaminated dust to the human body varies.

To this end, an air conditioner is widely used to control the temperature of the entire building and purify the air, and the air conditioner generates cold or hot air and supplies it to the room using a duct.

The air conditioner was equipped with a pre-filter for collecting coarse particles, an activated carbon filter for collecting fine particles, and a HEPA filter for purifying air. However, when a fine filter having such a structure is applied, there is a problem in that the pressure loss increases and the efficiency of blowing air decreases.
