Indoor Fresh Air Apparatus

Abstract

The present invention provides an indoor fresh air apparatus, comprising a body, an elementary filtering means, a deodorizing module, a blowing-in machine, a first haze removing module, a second haze removing module and a third haze removing module. The body is provided with an air-in passage serving as an air-in end and an air-out passage serving as an air-out end. The elementary filtering means is disposed at the air-in end; the deodorizing module is disposed within the air-in passage; and the blowing-in machine is disposed at the air-out end. The air-in passage, the first haze removing module, the second haze removing module, the third haze removing module and the air-out passage are connected in order. The air treatment unit provided by the present invention is capable of not only completely recovering cold energy or heat energy of indoor air, but also effectively treating indoor and outdoor PM2.5 and harmful gases.

Description

TECHNICAL FIELD[0001]The present invention relates to a technology of handling indoor and outdoor air flow in a building, and in particular to an indoor fresh air apparatus.BACKGROUND OF THE INVENTION[0002]PM2.5 and formaldehyde in air influence people's life and health; therefore, it has become a hot research topic for domestic and foreign experts of how to effectively remove indoor and outdoor PM2.5 and indoor formaldehyde and Volatile Organic Compounds (VOCs). At present, a wide variety of fresh air fans for removing PM2.5 and harmful gases such as formaldehyde and VOC in air may be found on the market, which, however, can hardly meet practical requirements in real estate development due to defects thereof, including being influenced by ventilation resistance of a filtering means, complicated maintenance and replacement, large structure size, difficult energy recovery, etc. In addition, although an air cleaning functional part is usually disposed within a common air conditioner, ...

AI Technical Summary

Benefits of technology

The present invention provides an indoor fresh air apparatus that can bring in outdoor fresh air and treat indoor and outdoor PM2.5, harmful gases, and odors. The air treatment unit can completely recover the energy of indoor air and effectively treat harmful gases such as formaldehyde and VOCs. This results in a more comfortable and healthy indoor environment.

Problems solved by technology

At present, a wide variety of fresh air fans for removing PM2.5 and harmful gases such as formaldehyde and VOC in air may be found on the market, which, however, can hardly meet practical requirements in real estate development due to defects thereof, including being influenced by ventilation resistance of a filtering means, complicated maintenance and replacement, large structure size, difficult energy recovery, etc.

In addition, although an air cleaning functional part is usually disposed within a common air conditioner, the air cleaning functional part can only provide a highly limited cleaning conditioning function without completely meeting comprehensive pollution treatment requirements such as PM2.5 removal, sterilization and disinfection due to limitations of ventilation resistance and installation space.
