[0038] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, an air conditioner with oxygen supply function includes a refrigeration system 100, a condensing branch 200, an oxygen production system 300, an outdoor unit 400, and an indoor unit 500. The refrigeration system 100 is used to transfer heat from the indoor environment to the outdoor environment, thereby realizing the refrigeration function of the air conditioner. The condensing branch 200 is used to cool the oxygen production system 300 to remove moisture from the air inside the oxygen production system 300 and to lower the temperature of the gas in the oxygen production system 300. The oxygen production system 300 is used to produce oxygen and deliver the produced oxygen to the indoor environment to increase the oxygen concentration in the indoor air. The outdoor unit 400 and the indoor unit 500 are used to integrate the refrigeration system 100, the condensing branch 200, and the oxygen production system 300. The outdoor unit 400 is placed outdoors, and the indoor unit 500 is placed indoors. The outdoor unit 400 and the indoor unit 500 are fluidly connected together via a connecting pipe (not marked in the figure) to allow refrigerant to circulate between them.

[0039] like Figure 1As shown, in some embodiments of the present invention, the refrigeration system 100 includes a compressor 101, a reversing valve 102, a condenser 103, a dryer filter 104, an electronic expansion valve 105, a refrigeration evaporator 106, and a liquid receiver 107. The compressor 101, reversing valve 102, condenser 103, dryer filter 104, electronic expansion valve 105, refrigeration evaporator 106, reversing valve 102, and liquid receiver 107 are sequentially fluidly connected so that the refrigerant can circulate along the following path: compressor 101 → reversing valve 102 → condenser 103 → dryer filter 104 → electronic expansion valve 105 → refrigeration evaporator 106 → reversing valve 102 → liquid receiver 107 → compressor 101.

[0040] The reversing valve 102 includes four ports, through which it is fluidly connected to the compressor 101, condenser 103, evaporator 106, and receiver 107, respectively. The reversing valve 102 directs refrigerant from the compressor 101 to the condenser 103, and refrigerant from the evaporator 106 to the receiver 107; it also directs refrigerant from the compressor 101 to the evaporator 106, and refrigerant from the condenser 103 to the receiver 107.

[0041] Continue reading Figure 1 In some embodiments of the present invention, the condensing branch 200 includes a throttling member 201 and a condensing evaporator 202 connected in series. Specifically, the inlet of the throttling member 201 is fluidly connected to the outlet of the compressor 101, and the outlet of the condensing evaporator 202 is fluidly connected to the inlet of the compressor 101. In the condensing branch 200, the refrigerant pressure decreases after flowing through the throttling member 201, and then flows through the condensing evaporator 202 to absorb heat.

[0042] Furthermore, in other embodiments of the present invention, those skilled in the art may, as needed, connect the inlet of the throttling member 201 to the outlet of other components within the refrigeration system 100, and connect the outlet of the condenser-evaporator 202 to the inlet of other components within the refrigeration system 100. For example, the inlet of the throttling member 201 may be connected to the outlet of the condenser 103, and the outlet of the condenser-evaporator 202 may be connected to the inlet of the liquid receiver 107.

[0043] In this invention, the throttling component 201 is preferably an electronic expansion valve. Alternatively, those skilled in the art can also configure the throttling component 201 as any other feasible component, such as a capillary tube, as needed. It should be noted that if the throttling component 201 is a capillary tube, a valve needs to be configured for the condenser branch 200 to control whether the refrigerant in the refrigeration system 100 flows to the condenser branch 200.

[0044] Continue reading Figure 1In some embodiments of the present invention, the oxygen generation system 300 includes a temperature sensor 301, an air filter 302, an air compressor 303, a condenser 304, a water-air separator 305, an oxygen separator 306, a first back pressure valve 307, a second back pressure valve 308, an oxygen concentration sensor 310, a flow sensor 311, and an ultrasonic vibrator 312. Among them, temperature sensor 301 is used to detect the temperature of air in the outdoor environment; air filter device 302 is used to filter air; air compressor 303 is used to draw air from the environment and deliver the air to condenser pipe 304; condenser pipe 304 is thermally connected to condenser evaporator 202 and is used to cool the air inside; water vapor separator 305 is used to separate water vapor inside; oxygen separator 306 is used to separate oxygen from the air; oxygen concentration sensor 310 is used to detect the oxygen concentration of oxygen discharged from oxygen separator 306; flow sensor 311 is used to detect the flow rate of oxygen discharged from oxygen separator 306; ultrasonic vibrator 312 is used to provide vibration to oxygen separator 306.

[0045] Although not shown in the figures, in some embodiments of the present invention, the condenser tube 304 is configured as a metal tube and is wound around the condenser evaporator 202.

[0046] In other embodiments of the present invention, those skilled in the art may, as needed, configure the condenser tube 304 with any other feasible structure and thermally connect the condenser tube 304 to the condenser-evaporator 202 in any other feasible manner. For example, the condenser tube 304 may be configured as a coil wound in a spiral or serpentine manner and fitted together with the condenser-evaporator 202.

[0047] Continue reading Figure 1 The air filter 302, air compressor 303, condenser 304, water-gas separator 305, oxygen separator 306 and first back pressure valve 307 are fluidly connected in sequence, and the second back pressure valve 308 is fluidly connected to the water-gas separator 305.

[0048] Continue reading Figure 1 The water-gas separator 305 includes a water-gas inlet 3051, an air outlet 3052, and a water outlet 3053. The water-gas separator 305 is fluidly connected to the condenser 304 through the water-gas inlet 3051, fluidly connected to the oxygen separator 306 through the air outlet 3052, and fluidly connected to the second back pressure valve 308 through the water outlet 3053.

[0049] Continue reading Figure 1The oxygen separator 306 includes an air inlet 3061, an exhaust gas outlet 3062, an oxygen outlet 3063, and a drain outlet 3064. The oxygen separator 306 is fluidly connected to the air outlet 3052 of the water-air separator 305 through the air inlet 3061, fluidly connected to the first back pressure valve 307 through the exhaust gas outlet 3062, and fluidly connected to the flow sensor 311 through the oxygen outlet 3063.

[0050] Optionally, the drain port 3064 of the oxygen separator 306 is fluidly connected to the outlet or inlet of the second back pressure valve 308. If the drain port 3064 of the oxygen separator 306 is fluidly connected to the outlet of the second back pressure valve 308, then a shut-off valve, check valve, or back pressure valve needs to be installed at the drain port 3064 of the oxygen separator 306 to control the connection between the drain port 3064 and the outside.

[0051] like Figure 3 As shown, in some embodiments of the present invention, the oxygen separator 306 further includes a condensation chamber 3065 and a tubular fiber membrane 3066, wherein the condensation chamber 3065 is in communication with a drain outlet 3064. Optionally, the condensation chamber 3065 is also in communication with an air inlet 3061 and an exhaust outlet 3062.

[0052] Continue reading Figure 3 In some embodiments of the present invention, the oxygen separator 306 further includes a tubular fiber membrane 3066, through which the oxygen separator 306 separates oxygen from the air. Since the material of the tubular fiber membrane 3066 that separates oxygen from the air is common knowledge in the art, it will not be described in detail here.

[0053] Furthermore, the ultrasonic vibrator 312 is mounted on the oxygen separator 306, and the ultrasonic vibrator 312 is configured such that the vibration direction of the wave it generates is perpendicular to the extension direction of the tubular fiber membrane 3066.

[0054] like Figure 2 As shown, the oxygen generation system 300 also includes an oxygen delivery pipe 313 communicating with the oxygen outlet 3063 of the oxygen separator 306. The oxygen delivery pipe 313 extends into the room through its end away from the oxygen outlet 3063. Specifically, the oxygen delivery pipe 313 is connected to a flow sensor 311, thereby achieving fluid connection between it and the oxygen outlet 3063.

[0055] Optionally, the end of the oxygen delivery tube 313 away from the oxygen outlet 3063 is located at the air outlet of the indoor air conditioning unit 500. Specifically, the oxygen delivery tube 313 and the connecting pipe of the air conditioner (not marked in the figure) are wrapped together and extend into the indoor air conditioning unit 500.

[0056] Furthermore, although not shown in the figures, in some embodiments of the present invention, the refrigeration system 100 includes a portion integrated on the outdoor unit 400 and a portion integrated on the indoor unit 500. Exemplarily, all parts of the refrigeration system 100 except for the evaporator 106 and the connecting pipe are disposed on the outdoor unit 400, and the evaporator 106 of the refrigeration system 100 is disposed within the indoor unit 500.

[0057] Furthermore, the entire condenser branch 200 is integrated into the outdoor unit 400 of the air conditioner.

[0058] Furthermore, all parts of the oxygen generation system 300 except for the oxygen delivery pipe 313 are installed inside the outdoor unit 400 of the air conditioner to reduce the noise impact on the indoor environment when the oxygen generation system 300 is working.

[0059] like Figure 2 As shown, in some embodiments of the present invention, the air conditioner further includes a controller 600 configured to control the air conditioner to perform oxygen generation and cleaning steps.

[0060] like Figure 4 As shown, the oxygen production steps include:

[0061] Step S110: Control the air compressor 303 to run and open the first back pressure valve 307.

[0062] In some embodiments of the present invention, the opening degree of the first back pressure valve 307 can be adjusted. In other words, the opening pressure of the first back pressure valve 307 can be adjusted to control the air pressure inside the oxygen separator 306 according to the adjustment pressure of the first back pressure valve 307, thereby controlling the pressure difference between the inside and outside of the tubular fiber membrane 3066, and thus controlling the oxygen production rate of the tubular fiber membrane 3066.

[0063] Step S120: Determine whether the current outdoor temperature has reached the preset temperature.

[0064] The preset temperature can be any feasible temperature, such as 15℃, 21℃, 30℃, 35℃, etc.

[0065] Step S130: Based on the judgment result, control the opening and closing of the throttling component 201 and the second back pressure valve 308.

[0066] Specifically, if the current temperature reaches the preset temperature, the throttling component 201 and the second back pressure valve 308 are opened.

[0067] If the current temperature does not reach the preset temperature, the throttling component 201 and the second back pressure valve 308 are closed.

[0068] Those skilled in the art will understand that if the current temperature reaches the preset temperature, it indicates that the moisture content in the controlled environment is high, requiring dehumidification of the air. By opening the throttling component 201, the condenser-evaporator 202 can cool the condenser tube 304, lowering the temperature of the air inside the condenser tube 304 and liquefying the water vapor in the air. Meanwhile, opening the second back pressure valve 308 can discharge water from the water-air separator 305, preventing water from entering the oxygen separator 306 and affecting its oxygen production efficiency.

[0069] Step S140: Determine whether the current oxygen concentration value detected by the oxygen concentration sensor 310 is within the preset oxygen concentration range.

[0070] The preset oxygen concentration range is a value set by the user. Furthermore, the preset oxygen concentration range can be a numerical range or a specific value. Specifically, the preset oxygen concentration range can be any numerical range or value within the range of 23% to 43%, such as 23%-30%, 25%-32%, 29%-38%, 27%, 33%, 40%, 41%, etc.

[0071] Step S150: Based on the judgment result, adjust the opening degree of the first back pressure valve 307.

[0072] Specifically, if the current oxygen concentration is within the preset oxygen concentration range, the first back pressure valve 307 is kept at its current opening. If the current oxygen concentration is less than the preset oxygen concentration range, the first back pressure valve 307 is reduced in opening. If the current oxygen concentration is greater than the preset oxygen concentration range, the first back pressure valve 307 is increased in opening.

[0073] Preferably, step S140 is executed once every preset time interval (e.g., 1 second, 5 seconds, 30 seconds, etc.). In step S150, the opening degree of the first back pressure valve 307 is adjusted by 5% or 30% of the total opening degree each time.

[0074] It should be noted that although steps S110 to S150 are referenced Figure 4 The steps are described in chronological order, but this does not mean that steps S110 to S150 must be executed in that order. For example, steps S120 and S140 can be executed simultaneously, or steps S140 and S150 can be executed first, followed by steps S120 and S130.

[0075] like Figure 5 As shown, the cleaning steps include:

[0076] In step S210, the air compressor 303 is controlled to operate, the opening of the first back pressure valve 307 is adjusted to the maximum, and the second back pressure valve 308 is closed, so that air flows along the following path: air filter device 302 → air compressor 303 → condenser 304 → water-air separator 305 → oxygen separator 306 → first back pressure valve 307, in order to clean the oxygen separator 306.

[0077] Alternatively, when the first back pressure valve 307 is opened, the ultrasonic vibrator 312 is activated so that the ultrasonic vibrator 312 transmits radial vibrations to the tubular fiber membrane 3066, shaking off the debris on the tubular fiber membrane 3066, which is then flushed out by the flowing air.

[0078] In step S220, control the air compressor 303 to run, close the first back pressure valve 307, and adjust the opening of the second back pressure valve 308 to the maximum so that air flows along the following path: air filter 302 → air compressor 303 → condenser 304 → water separator 305 → second back pressure valve 308, so as to clean the condenser 304 and the water separator 305.

[0079] In other embodiments of the present invention, those skilled in the art may omit any one of steps S230 and S220 as needed.

[0080] Furthermore, in other embodiments of the present invention, those skilled in the art may omit at least one of the oxygen generation system 300 as needed, such as omitting the air filter device 302 and / or the flow sensor 311.

[0081] Based on the foregoing description, those skilled in the art will understand that, in the oxygen generation process of the oxygen generation system 300, by integrating the oxygen generation system 300 into the air conditioner, the air conditioner can transfer outdoor oxygen to the indoor air through the oxygen generation system 300, thereby increasing the oxygen concentration of the indoor air. At the same time, it also avoids excessively high temperatures of the oxygen entering the room.

[0082] Furthermore, by determining whether the current temperature detected by the temperature sensor 301 has reached the preset temperature, and then according to the determination result, controlling the opening of the throttling component 201 and the second back pressure valve 308, the oxygen generation system 300 can automatically control the opening and closing of the throttling component 304 and the second back pressure valve 308 according to the current temperature, thus avoiding the water condensed when the air temperature is high from affecting the oxygen generation efficiency of the oxygen separator 306.

[0083] Furthermore, during the operation of the air compressor 303, by adjusting the opening of the first back pressure valve 307 to its maximum and closing the second back pressure valve 308, the oxygen generation system 300 automatically cleans the oxygen separator 306. During the operation of the air compressor 303, by closing the first back pressure valve 307 and adjusting the opening of the second back pressure valve 308 to its maximum, the oxygen generation system 300 automatically cleans the condenser 304 and the water-air separator 305.

[0084] In addition, in other embodiments of the present invention, those skilled in the art may, as needed, keep the throttling member 201 in the open state during the oxygen production process of the oxygen production system 300, so as to reduce the temperature of the air in the oxygen production system 300 through the condenser evaporator 202, thereby reducing the temperature of the oxygen entering the room and preventing the oxygen from causing a temperature rise in the room.

[0085] The technical solutions of the present invention have been described in conjunction with several embodiments above. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is not limited to these specific embodiments. Without departing from the technical principles of the present invention, those skilled in the art can disassemble and combine the technical solutions in the above embodiments, and can also make equivalent changes or substitutions to related technical features. Any changes, equivalent substitutions, improvements, etc., made within the technical concept and / or technical principles of the present invention will fall within the scope of protection of the present invention.
