Air purifying system and control method thereof

Abstract

Provided is an air cleaning system and its control method capable of performing a ventilating operation and an air cleaning operation in accordance with a contamination state of the indoor air. This air cleaning system comprises a ventilating unit, an air cleaning unit, a sensor for detecting the concentration of contamination of the indoor air, and a controller for deciding one of a plurality of operation modes in accordance with the concentration of contamination of the indoor air detected by the sensor, and controlling the ventilating unit and the air cleaning unit in accordance with the decided operation mode.

Description

technical field [0001] The invention relates to an air purification system capable of air purification and ventilation and a control method thereof. Background technique [0002] The air purification system has an air purification unit that filters dust, bacteria, pollutants, etc. in the air to provide purified pure air. [0003] During the use of the air purification system, although the room must be sealed in order to purify the indoor air, the carbon dioxide produced by people's breathing will still pollute the indoor air. [0004] In view of these circumstances, an air purification system including a ventilation unit that exhausts indoor air to the outside and takes in fresh outdoor air to ventilate the room has been proposed. [0005] This air purification system is further divided into a method in which the user directly sets the air purification function and a ventilation function, and a method in which the relevant functions are set by using a sensor that detects th...

AI Technical Summary

Problems solved by technology

However, during operation in the ventilation mode, since the air cleaning operation is performed in response to the dust sensor, the ventilation operation may be interrupted when the room is not sufficiently ventilated.

In addition, during the operation of the air purification mode, since the ventilation operation is performed in response to the gas sensor, the air purification operation may be interrupted when the indoor dust is not completely purified.

As a result, the relevant operating modes cannot be operated smoothly

[0008] On the other hand, in the existing air purification system, even if the user goes out without directly inputting the operation stop command, for example, when the person is not in the room, the air purification system also works in vain, and there is a problem of wasting power.
