Description

SYSTEM AND METHOD FOR MAINTAINING THE INDOOR AIR QUALITY OF THE INDIVIDUAL ROOM AT A CLEAN CONDITION THROUGH THE DEVICE CONTAINING AIR QUALITY GAS SENSORS INSTALLED IN THE INDIVIDUAL ROOMS AND FOR CLEANING THE DUSTS IN THE FLOOR}

The present invention relates to a smart environmental management system and method for helping to control the indoor air quality of the room and dust cleaning of the floor, and more specifically, individually by a gas measuring unit such as a gas sensor installed in each room and an integrated air conditioning system installed centrally. The present invention relates to a system and method for measuring air quality in a room and forcibly circulating air in a specific room to maintain and clean the floor.

As the industrial society has been advanced and the construction technology of residential facilities such as apartments, residential complexes and officetels has been advanced, the sealing technology of windows and doors has been developed to reduce the waste of energy.

Therefore, living gas or toxic gas from building materials or resident people remains in the room and is considered to be a major cause of harm to people's health.

For example, radon gas, which is a radiation gas evaporated from cement or stone, or volatile gases such as formaldehyde or toluene, emitted from paint, furniture, and wallpaper, accumulate in an enclosed space. As a result, many people who have never smoked are considered to be a major cause of lung cancer. In fact, in 2010, the United States estimates that more than 20,000 people have lung cancer caused by indoor pollution every year.

Therefore, the technology of keeping indoor air of each room clean is very important in the collective housing facilities or the assembly office buildings. However, because there are so many kinds of harmful gases in the room, it is practically impossible to measure and manage them all.

However, the results show that the higher the concentration of carbon dioxide in the room, the higher the concentration of other harmful gases. Therefore, if only one concentration of carbon dioxide is measured and the value is increased above a certain level by using the measured concentration of carbon dioxide, the indoor air is removed by inhaling the indoor air and ventilating it outside to remove the harmful gas. Quality can be kept clean.

In fact, in the case of a large AI building, the indoor air is mixed with indoor air by using a carbon dioxide sensor installed in the central air conditioning system so that the concentration of carbon dioxide is less than 1000 ppm, and the indoor air is kept clean through the air conditioning hood installed on the roof. Doing.

In addition, some high-end apartments operate a system that cleans the indoor air by periodically or manually circulating the indoor air through a filter included in the air conditioning system. However, since most air circulation ports are located at a high place such as a ceiling, there is a limitation in removing heavy harmful gas, and there is a disadvantage in that noise or high use cost must be paid because the air circulation must always be returned.

In addition, conventionally, an air purifier is used to remove dust from air pollutants by circulating air through a fine filter to remove dust from the room by attaching it to the filter, and dust on the floor is removed by a robot cleaner or vacuum cleaner. The source of contamination is being removed. However, this is inconvenient because it involves human effort and costs and effort accordingly.
