Problems solved by technology

[0006] However, since the above-mentioned typical air-conditioning system only considers the temperature control of the room, and does not consider the degree of air pollution in the room, the air-conditioning system cannot reflect some factors that are very important for operation, such as the degree of pollution of the indoor air, the degree of pollution of the indoor air pollution rate
[0007] Also, typical air conditioning systems do not properly handle this change in indoor air as it becomes rapidly polluted for various reasons, such as indoor smoke or a sudden number of people using the room

Embodiment Construction

[0030] Hereinafter, reference is made to the preferred embodiments of the present invention in detail, and examples thereof are shown in the accompanying drawings. Whenever possible, the same reference numerals used throughout the drawings refer to the same or similar components, and repeated descriptions thereof will be omitted. figure 1 An air conditioning system is schematically shown.

[0031] Refer to figure 1 , The indoor unit 10 is installed on the ceiling of the room so as to communicate with the room. The indoor unit 10 includes: an expansion device (not shown) to expand the refrigerant; an indoor heat exchanger (not shown) to exchange heat between the expanded refrigerant and indoor air; and an indoor fan (not shown) Out), used to suck indoor air into the indoor unit 10, and then send the indoor air into the room through the indoor heat exchanger.

[0032] Although not shown, the indoor unit 10 has a filter assembly installed therein. The filter assembly removes impuri...

Abstract

Method for controlling an air flow rate of an air conditioning system, including the steps of measuring a concentration of volatile organic compounds in air periodically, calculating a value of concentration change from concentration values measured at the present time and in the past, and controlling the flow rate of air for cleaning or ventilating a room with reference to the present concentration and value of concentration change, whereby controlling a flow rate of room cleaning or ventilating air to cope, not only with concentration of organic compounds, but also with rapid change of the concentration of the organic compounds in the air.

Description

Technical field [0001] The present invention relates to an air-conditioning system, in particular to a method for controlling the air volume of the air-conditioning system. In the method, room purification or ventilation is controlled not only according to the concentration of organic compounds in the air but also according to the rate of change of the concentration of organic compounds in the air. The air volume. Background technique [0002] The air-conditioning system is a device that keeps the room air in the most suitable state according to the use of the air, and includes air conditioners, air purifiers, and ventilation equipment. The air conditioner uses the characteristics of the refrigerant to absorb heat from the surrounding environment or discharge heat to the surrounding environment when the refrigerant undergoes a phase change to cool or heat the room. [0003] The air purifier sucks air from the room, removes impurities such as dust, and returns the purified air to ...
