Description

TECHNICAL FIELD

[0001] The present invention relates to an air conditioning device including an oxygen generator. BACKGROUND

[0002] A conventional oxygen generator uses the characteristics of an adsorbent called zeolite to adsorb gas molecules.

[0003] Nitrogen, which accounts for about 80% of the atmosphere, is easily adsorbed by zeolite, and thus when air passes through the zeolite, the nitrogen component in the air is adsorbed, and the oxygen concentration in the air increases as the nitrogen component decreases.

[0004] A small oxygen generator mostly includes an oxygen generator equipped with an adsorption tower made of a zeolite adsorbent, and an air compressor that supplies compressed air to the oxygen generator, and the adsorption power is generated by the compressed air supplied to the oxygen generator. Unlike this, relatively more nitrogen is adsorbed into the adsorption tower, thereby generating concentrated oxygen.

[0005] The oxygen concentrated in the above-described manner is supplied to a desired place through an oxygen storage tank, and when the air pressure applied to the adsorption tower is released and the internal pressure is lowered to atmospheric pressure, the nitrogen adsorbed in the adsorption tower is separated.

[0006] Thus, the method of generating concentrated oxygen by supplying compressed air to the adsorption tower and desorbing and discharging the nitrogen adsorbed in the adsorption tower at normal pressure is called a pressure swing adsorption (PSA) method.

[0007] A large commercial oxygen generator uses a vacuum swing adsorption (VSA) method, not the compressed pressure swing adsorption method as described above, to separate oxygen from nitrogen in the atmosphere.

[0008] The vacuum swing adsorption (VSA) method is a method of passing the atmosphere through the oxygen generator at normal pressure, adsorbing more nitrogen into the adsorption tower, and thereby concentrating oxygen.

[0009] The nitrogen adsorbed in the adsorption tower is desorbed and separated by generating a vacuum in the oxygen concentrator.

[0053] Oxygen is widely used for industrial and medical purposes, and in the last 30 years, much research has been conducted on technologies for concentrating oxygen from air. Methods for producing high-concentration oxygen mainly include cryogenic and non-cryogenic methods. Early high-concentration oxygen technologies used low-temperature methods, but had the disadvantage of high energy consumption.

[0054] Recently, non-cryogenic methods mainly using pressure swing adsorption (PSA) or vacuum swing adsorption (VSA) processes are used. In these processes, nitrogen adsorbents are used as fillers, and zeolites are mainly used as nitrogen adsorbents.

[0055] Zeolites are ion-exchanged cations that form an electrostatic field with a strong mutual attraction with adsorbents. Zeolites are easily exchanged with cations, so they have the advantage of being able to select and apply appropriate cations according to the gas mixture to be separated. Variables that affect the adsorption capacity of zeolites for nitrogen adsorbents include silica and alumina in the zeolite lattice. These include the molar ratio, the type and position of ion-exchanged cations, etc.

[0056] One basic requirement for the nitrogen adsorption performance of zeolites is that the nitrogen adsorption capacity increases as the Si / Al molar ratio approaches 1 and as the cationic charge density increases.

[0126] Also, it is not shown that when the fine dust sensor is provided and the amount of dust less than PM 2.5 exceeds a set value, the indoor blowing fan 175 is automatically operated to filter the indoor air.

[0127] The carbon dioxide sensing unit 515 is a carbon dioxide sensor provided in the indoor unit casing 110. The carbon dioxide sensor measures the concentration of carbon dioxide by the change in the amount of infrared absorption using the property of carbon dioxide molecules that absorb light in a specific infrared range.

[0128] The first direction switching valve 275 is a three-way valve.

[0129] The control method of the air conditioning apparatus including an oxygen generator according to an embodiment of the present application includes the steps of detecting the indoor carbon dioxide concentration by the carbon dioxide detecting unit 515, and detecting the indoor oxygen concentration by the oxygen detecting unit 514 S10, comparing the carbon dioxide concentration detected in step S10 with a first carbon dioxide reference value S20, if the carbon dioxide concentration is greater than the first carbon dioxide reference value in step S20, sucking the indoor air, forcibly discharging the sucked indoor air to the outside S30, comparing the carbon dioxide concentration with a second carbon dioxide reference value after step S30, if the carbon dioxide concentration is less than the second carbon dioxide reference value, forcibly discharging the sucked indoor air to the outside S30. In step S40, sucking the indoor air, discharging the same back to the indoor S50, comparing the oxygen concentration with a first oxygen reference value after step S50 S60, if the oxygen concentration is less than the first oxygen reference value in step S60, sucking the outdoor air, generating oxygen by the zeolite assembly 400 to which the outdoor air is supplied, and discharging the high concentration oxygen to the indoor S70, comparing the oxygen concentration with a second oxygen reference value after step S70 S80, if the oxygen concentration is higher than the second oxygen reference value in step S80, sucking the indoor air, supplying the sucked indoor air to the zeolite assembly 400 to generate oxygen, and then discharging the high concentration oxygen to the indoor S90.

[0130] In the control method of the air conditioning apparatus including an oxygen generator according to an embodiment of the present application, the radical generation module 140 is always operated throughout the entire process. In this embodiment, the first carbon dioxide reference value is 1000 ppm, and the second carbon dioxide reference value is 500 ppm.

[0131] If the indoor carbon dioxide exceeds 1000 ppm, it is determined that the carbon dioxide is high in step S20. When the carbon dioxide concentration is high, it is difficult to rapidly reduce the carbon dioxide concentration even if the indoor air is circulated.

[0132] Accordingly, in step S30, indoor air is discharged to the outside, and outdoor air is supplied to the inside to rapidly reduce the carbon dioxide concentration.

[0133] To discharge the indoor air to the outside in step S30, the control unit 500 operates the air compressor 220, opens the first suction on / off valve 271a, and closes the third suction on / off valve 273a.

[0134] If the carbon dioxide concentration is less than the second carbon dioxide reference value (500 ppm in this example), the process returns to step S10.

[0135] If step S40 is satisfied, it is determined that the indoor carbon dioxide concentration is within the set range, and in step S50, the indoor air is circulated back to the inside.

[0136] If step S40 is not satisfied, it returns to step S30.

[0137] In step S50, the control unit 500 closes the first intake valve 271a and operates the indoor blower fan 175 to circulate the indoor air.

[0138] If the oxygen concentration is less than the first oxygen reference value, in step S70, outdoor air is sucked, oxygen is concentrated by supplying outdoor intake air to the zeolite assembly 400, and then it is discharged to the inside. In this example, the first oxygen reference value is 20.9%, and the second oxygen reference value is 23.0%. The first oxygen reference value or the second oxygen reference value is something you can change.

[0139] To this end, in step S70, the control unit 500 closes the first suction on / off valve 271a and opens the third suction on / off valve 273a.

[0140] If step S60 is not satisfied, it returns to step S50.

[0141] Next, if the indoor oxygen concentration is greater than the second oxygen reference value, in step S90, the indoor air is circulated. To this end, in step S90, the control unit 500 closes the third discharge on / off valve 283a and only operates the indoor blower fan 175.

[0142] The air compressor 220 is individually controlled according to the oxygen capacity stored in the storage tank 230.

[0143] In addition, although not separately described, a check valve can also be provided to force the flow direction of indoor air and outdoor air, which is a well-known technical matter to those skilled in the art, and therefore will not be described in detail.

[0144] In the detailed description of the application it has been described a particular embodiment, but of course various modifications can be made without departing from the scope of the application. Therefore, the scope of the application should not be limited to the described embodiment, but should be determined not only by the scope of the patent claims described below, but also by the scope of the patent claims and their equivalents.
