Problems solved by technology

However, since the air of a shut tight room is polluted gradually as time goes by, the air conditioning system ventilates the room periodically, to supply fresh air to the room.
However, since the foregoing typical air conditioning system is operative only taking the room temperature into account without a level of air pollution of the room, the air conditioning system fails to refle

Example

[0034] Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. In describing the embodiments, identical parts will be given the same names and reference symbols, and repetitive description of which will be omitted. FIG. 1 illustrates a diagram of an air conditioning system, schematically.

[0035] Referring to FIG. 1, there is an indoor unit 10 installed on a ceiling of a room so as to be in communication with a room. The indoor unit 10 includes an expansion device (not shown) for expanding refrigerant, an indoor heat exchanger (not shown) for making the expanded refrigerant to heat exchange with the room air, and an indoor fan (not shown) for drawing the room air into the indoor unit 10, and supplying the room air to the room again via the indoor heat exchanger.

[0036] Though not shown, the indoor unit 10 has a filter assembly provided therein. The filter assembly 10 removes foreign ma...

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

[0001] This application claims the benefit of the Korean Application No. P2004-0004152 filed on Jan. 20, 2004, which is hereby incorporated by reference. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to air conditioning systems, and more particularly, to a method for controlling an air flow rate of an air conditioning system, in which a flow rate of room cleaning or ventilating air is controlled to cope, not only with concentration of organic compounds, but also with rapid change of the concentration of the organic compounds in the air. [0004] 2. Background of the Related Art [0005] The air conditioning system is an apparatus for maintaining room air at a most proper state according to use or purpose of the air, inclusive of air conditioners, air cleaners, ventilating devices. The air conditioner cools or heats the room by using a property of the refrigerant in which the refrigerant discharges or absorbs heat to / from an environment...
