For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] In the field of air conditioning related technology, such as oxygen-generating air conditioners, oxygen-generating modules are generally added to the outdoor unit and transported to the indoor side to increase the oxygen content in the use environment and improve user comfort. However, since the principle of the oxygen-generating module is to transport air to the nitrogen-oxygen separator through the operation of the air compressor to filter out oxygen and nitrogen, the air temperature transported by the air compressor is relatively high, resulting in unstable oxygen concentration output by the nitrogen-oxygen separator after processing the air.

[0046] Based on this, the following embodiments are proposed.

[0047] Embodiment 1:

[0048] like Figure 1-2 As shown, this embodiment provides an oxygen-generating air conditioner, comprising:

[0049] A host unit 1, the host unit 1 comprising an indoor heat exchanger 101 and an outdoor heat exchanger 102, a compressor 106 and a throttle valve assembly being arranged on a refrigerant flow path between the indoor heat exchanger 101 and the outdoor heat exchanger 102, the throttle valve assembly comprising a first throttle valve 103 and a second throttle valve 104, at least a portion of the flow path between the first throttle valve 103 and the second throttle valve 104 forming a first heat exchange flow path 105;

[0050] The oxygen generator 2 comprises an air compressor 201 and a nitrogen-oxygen separator 202, wherein at least a portion of the flow path between the air compressor 201 and the nitrogen-oxygen separator 202 forms a second heat exchange flow path 203;

[0051] The first heat exchange flow path 105 and the second heat exchange flow path 203 are configured to form heat exchange with each other, so that the first heat exchange flow path 105 can cool the second heat exchange flow path 203 .

[0052] In this embodiment, the oxygen-generating air conditioner includes a main unit 1 and an oxygen-generating unit 2. The main unit 1 includes an indoor heat exchanger 101 and an outdoor heat exchanger 102, which are used to adjust the temperature of indoor air. A compressor 106, a four-way valve 107 and a throttle valve assembly are arranged on the flow path between the indoor heat exchanger 101 and the outdoor heat exchanger 102, so that the refrigerant can flow between the indoor heat exchanger 101 and the outdoor heat exchanger 102. The throttle valve assembly includes a first throttle valve 103 and a second throttle valve 104. By adjusting the opening of the first throttle valve 103 and the second throttle valve 104 respectively, the state of the refrigerant can be changed, thereby achieving heat absorption or heat release of the refrigerant. At least part of the flow path between the first throttle valve 103 and the second throttle valve 104 forms a first heat exchange flow path 105, which can exchange heat with surrounding objects. The compressor 106 discharges high-temperature and high-pressure gaseous refrigerant, which is converted into medium-temperature and high-pressure liquid refrigerant through heat exchange in the outdoor heat exchanger 102, and then converted into medium-pressure and low-temperature liquid refrigerant through the first throttle valve 103, so that the refrigerant in the first heat exchange flow path 105 is always in a medium-pressure and low-temperature liquid state. After the refrigerant passes through the secondary throttling of the second throttle valve 104, it will become a low-temperature and low-pressure liquid refrigerant. Finally, after being converted into a low-temperature and low-pressure gas through heat exchange in the indoor heat exchanger, it returns to the compressor 106 to complete a single refrigeration cycle.

[0053] The oxygen production unit 2 includes an air compressor 201 and a nitrogen-oxygen separator 202. The air compressor 201 can compress the air to push the air through the nitrogen-oxygen separator 202, thereby separating nitrogen and oxygen, and transporting the oxygen to the room and discharging the nitrogen to the outside. When the air is compressed, its temperature will increase, and the separation efficiency of the nitrogen-oxygen separator 202 for high-temperature air will decrease, resulting in a decrease in the amount of separated oxygen. Fig.10 As shown, the oxygen concentration law of air at different temperatures after passing through the nitrogen-oxygen separator 202, that is, after the molecular sieve treatment, is optimal when the temperature is controlled within 20°C to 35°C; therefore, it is necessary to cool the high-temperature air before it enters the nitrogen-oxygen separator 202. By forming at least part of the flow path between the air compressor 201 and the nitrogen-oxygen separator 202 into a second heat exchange flow path 203, the temperature of the air compressed by the air compressor 201 will change after passing through the second heat exchange flow path 203. By setting up a heat exchange between the first heat exchange flow path 105 and the second heat exchange flow path 203, the first heat exchange flow path 105 can achieve temperature increase or temperature decrease in the second heat exchange flow path 203 by means of close contact or air medium.

[0054] Preferably, the oxygen production section 2 is arranged on the outdoor heat exchanger 102 and is fully sealed so that the oxygen production section 2 does not need to exchange heat with the outdoor air through convection, thereby reducing the risk of ineffective heat exchange caused by contact between the first heat exchange flow path 105 and the second heat exchange flow path 203 and the external air.

[0055] Preferably, placing the first heat exchange channel 105 against the second heat exchange channel 203 can improve the heat exchange efficiency between the first heat exchange channel 105 and the second heat exchange channel 203 .

[0056] By setting up heat exchange between the first heat exchange flow path 105 of the main unit 1 and the second heat exchange flow path 203 of the oxygen production unit 2, the first heat exchange flow path 105 can reduce the temperature of the air in the second heat exchange flow path 203 before entering the nitrogen-oxygen separator 202 by means of close contact or air medium, thereby reducing the possibility of reduced efficiency of air separation by the nitrogen-oxygen separator 202, and there is no need to add additional cooling equipment between the air compressor 201 and the nitrogen-oxygen separator 202. The throttle valve assembly is set to a double throttling mode, which can utilize the low-temperature refrigerant in the middle section of the throttle valve assembly to exchange heat with the air before entering the nitrogen-oxygen separator 202, thereby reducing the air temperature output by the air compressor 201, so that the oxygen output by the nitrogen-oxygen separator 202 can be continuously and stably maintained within the concentration range required by the user, thereby improving the oxygen production efficiency of the oxygen-producing air conditioner.

[0057] Optionally, in an implementation of this embodiment, as Figure 3-6 As shown,

[0058] Heat exchange components 3 are disposed outside the first heat exchange flow path 105 and the second heat exchange flow path 203 , and the first heat exchange flow path 105 and the second heat exchange flow path 203 perform heat exchange through the heat exchange components 3 .

[0059] In this embodiment, a heat exchange component 3 is arranged outside the first heat exchange flow path 105 and the second heat exchange flow path 203. The heat exchange component 3 can be made of a heat conductive material with good heat exchange effect such as metal aluminum. An enclosing cavity is formed inside the heat exchange component 3. The first heat exchange flow path 105 and the second heat exchange flow path 203 are both arranged in the enclosing cavity, and heat exchange is performed in the enclosing cavity.

[0060] Preferably, the heat exchange element 3 can be set to a closed structure so that the surrounding cavity becomes a closed cavity, or the heat exchange element 3 can be set to have an open structure so that the surrounding cavity becomes an open cavity, so as to adapt to the setting methods of the first heat exchange flow path 105 and the second heat exchange flow path 203 in different installation spaces.

[0061] Preferably, the first heat exchange flow path 105 and the second heat exchange flow path 203 may all be embedded in or abutted against the inner wall of the heat exchange element 3, or may be embedded in or abutted against the inner wall of the heat exchange element 3 separately.

[0062] By providing the heat exchange element 3, the first heat exchange path 105 and the second heat exchange path 203 can perform heat exchange in the surrounding cavity, thereby reducing the heat exchange space of the first heat exchange path 105 and the second heat exchange path 203, and reducing the risk of invalid heat exchange between the first heat exchange path 105 and the second heat exchange path 203 due to contact with the external air, thereby improving the heat exchange efficiency between the first heat exchange path 105 and the second heat exchange path 203.

[0063] Optionally, in an implementation of this embodiment, as Figure 3-7 As shown,

[0064] The oxygen generator 2 further includes a housing 204, and the housing 204 is disposed at the top of the outdoor heat exchanger 102;

[0065] The side wall of the housing 204 is provided with a first outlet 2041 and a second outlet 2042, wherein the first outlet 2041 is communicated with the nitrogen outlet of the nitrogen-oxygen separator 202, and the second outlet 2042 is communicated with the oxygen outlet of the nitrogen-oxygen separator 202;

[0066] The housing 204 forms a mounting cavity 2043, and the air compressor 201, the nitrogen and oxygen separator 202 and the heat exchange element 3 are all arranged in the mounting cavity 2043;

[0067] The heat exchange element 3 is located between the air compressor 201 and the nitrogen oxygen separator 202 .

[0068] In this embodiment, the oxygen production unit 2 further includes a housing 204, which is disposed at the top of the main unit 1 to facilitate loading and unloading of the oxygen production unit 2. A first outlet 2041 and a second outlet 2042 are provided on the side wall of the housing 204 for outputting gas. The first outlet 2041 is connected to the nitrogen output port of the nitrogen-oxygen separator 202, and the second outlet 2042 is connected to the oxygen outlet of the nitrogen-oxygen separator 202, so that the first outlet 2041 outputs nitrogen and the second outlet 2042 outputs oxygen. An installation cavity 2043 is formed in the housing 204, and the air compressor 201, the nitrogen-oxygen separator 202 and the heat exchanger 3 are all disposed in the installation cavity 2043 to reduce the occupation of the installation space by the oxygen production unit 2. The heat exchange element 3 is arranged between the air compressor 201 and the nitrogen oxide separator 202, so that the first heat exchange flow path 105 and the second heat exchange flow path 203 are also located between the air compressor 201 and the nitrogen oxide separator 202, thereby avoiding increasing the detour distance of the first heat exchange flow path 105 and the second heat exchange flow path 203.

[0069] Preferably, the first heat exchange flow path 105 and the second heat exchange flow path 203 are both arranged in the form of coils in the heat exchange element 3, which can increase the heat exchange area of ​​the first heat exchange flow path 105 and the second heat exchange flow path 203, thereby improving the heat exchange efficiency between the first heat exchange flow path 105 and the second heat exchange flow path 203.

[0070] Preferably, a heat dissipation hole is provided on the side wall of the housing 204 close to the air compressor 201 for dissipating heat for the air compressor 201 .

[0071] By arranging the heat exchange element 3 between the air compressor 201 and the nitrogen oxygen separator 202, the lengths of the first heat exchange flow path 105 and the second heat exchange flow path 203 can be shortened, thereby reducing the volume of the oxygen production unit 2 by reducing the occupation of the installation space.

[0072] Optionally, in an implementation of this embodiment, as Figure 3-6 As shown,

[0073] The heat exchange element 3 is constructed as a shell structure or a solid structure, and a side wall of the heat exchange element 3 is provided with an opening 301 for the first heat exchange flow path 105 and the second heat exchange flow path 203 to pass through.

[0074] In this embodiment, when the heat exchange element 3 is constructed as a shell structure, a closed cavity is formed, and an opening 301 is opened on the side wall of the heat exchange element 3. The first heat exchange flow path 105 and the second heat exchange flow path 203 respectively pass through the opening 301 and enter the surrounding cavity for heat exchange.

[0075] By opening the opening 301 on the side wall of the heat exchanger 3, the first heat exchange flow path 105 and the second heat exchange flow path 203 enter the surrounding cavity through the opening 301, so that the sealing of the heat exchanger 3 can be ensured, thereby reducing the risk of the oxygen production part 2 having too many holes opened to improve heat dissipation, but causing excessive dust accumulation due to long-term operation and thus shortening the service life.

[0076] When the heat exchange element 3 is constructed as a solid structure, the first heat exchange flow path 105 and the second heat exchange flow path 203 penetrate the opening 301 in a mutually entangled manner to perform heat exchange in the solid structure.

[0077] Optionally, in an implementation of this embodiment, as Figure 7 As shown,

[0078] The first heat exchange flow path 105 has a continuous bend in the portion inside the heat exchange element 3;

[0079] The second heat exchange flow path 203 has a continuous bend in the portion inside the heat exchange element 3 .

[0080] In the present embodiment, the first heat exchange flow path 105 and the second heat exchange flow path 203 are both constructed as flow path sections having continuous bends, so that the heat exchange area of ​​the first heat exchange flow path 105 and the second heat exchange flow path 203 can be increased within the limited space of the surrounding cavity without increasing the volume of the oxygen production section 2, and the heat exchange efficiency between the first heat exchange flow path 105 and the second heat exchange flow path 203 can be further improved.

[0081] Preferably, U-shaped tubes are provided at the openings 301 of the first heat exchange flow path 105 and the second heat exchange flow path 203, and the number of U-shaped tubes corresponds to the number of openings 301. The U-shaped tubes include an inlet and an outlet, and the inlet and outlet of each U-shaped tube are in opposite directions. The U-shaped tubes can be made of other materials with excellent thermal conductivity and stability, such as metallic copper.

[0082] Optionally, in an implementation of this embodiment, as Figure 3 and Figure 5-7 As shown,

[0083] The first heat exchange flow path 105 has a refrigerant inlet end 1051 and a refrigerant outlet end 1052, the refrigerant inlet end 1051 is connected to the first throttle valve 103, and the refrigerant outlet end 1052 is connected to the second throttle valve 104;

[0084] The second heat exchange flow path 203 has an air output end 2031 and an air input end 2032 . The air output end 2031 is connected to the air inlet of the nitrogen oxygen separator 202 , and the air input end 2032 is connected to the output end of the air compressor 201 .

[0085] In this embodiment, the first heat exchange flow path 105 has a refrigerant inlet end 1051 and a refrigerant outlet end 1052. The refrigerant inlet end 1051 is connected to the first throttle valve 103, and the refrigerant outlet end 1052 is connected to the second throttle valve 104. When the air conditioner operates in the cooling mode, the refrigerant flows through the first throttle valve 103, evaporates and absorbs heat, and flows out from the refrigerant outlet end 1052. The refrigerant flows from the refrigerant outlet end 1052 through the second throttle valve 104 and then flows back to the compressor, thereby completing a single refrigeration cycle. The second heat exchange flow path 203 has an air output end 2031 and an air input end 2032. The air output end 2031 is connected to the air inlet of the nitrogen oxygen separator 202, and the air input end 2032 is connected to the output end of the air compressor 201. When the air flows from the air compressor 201 to the air input end 2032, the temperature of the air is relatively high. When the air flows from the air input end 2032 to the air output end 2031, its temperature is greatly reduced due to the heat exchange between the first heat exchange flow path 105 and the second heat exchange flow path 203, so that the air output end 2031 can output air with a lower temperature.

[0086] Preferably, when the air conditioner operates in heating mode, the refrigerant flows through the second throttle valve 104, evaporates and absorbs heat, and flows out from the refrigerant inlet end 1051. The refrigerant flows from the refrigerant inlet end 1051 through the first throttle valve 103 and then flows back to the compressor, thereby completing a single refrigeration cycle.

[0087] By setting the refrigerant inlet end 1051 and the refrigerant outlet end 1052 of the first heat exchange flow path 105 to be connected to the first throttle valve 103 and the second throttle valve 104 respectively, the air conditioner can make the refrigerant evaporate and absorb heat in the first heat exchange flow path 105 in both cooling mode and heating mode, thereby completing heat exchange between the first heat exchange flow path 105 and the second heat exchange flow path 203, and further enabling the air output end 2031 to output air with a lower temperature.

[0088] Optionally, in an implementation of this embodiment,

[0089] A temperature sensing element is provided between the air output end 2031 and the air inlet of the nitrogen oxygen separator 202 , and the temperature sensing element is used to monitor the temperature of the air entering the nitrogen oxygen separator 202 .

[0090] In this embodiment, a temperature sensing element is provided between the air output terminal 2031 and the air inlet of the nitrogen oxide separator 202. The temperature sensing element can monitor the air temperature before entering the air inlet of the nitrogen oxide separator 202. The temperature sensing element is electrically connected to the controller in the air conditioner, so that the controller can receive the data signal fed back by the temperature sensing element, and compare it with the preset target temperature threshold, and issue an instruction for the next operation after making a judgment.

[0091] When the temperature sensing component detects that the air temperature before entering the air inlet of the nitrogen oxygen separator 202 is high, the air in the second heat exchange flow path 203 needs to be cooled. At this time, the temperature sensing component can feed back the data signal to the controller, and the controller controls the operation of the first heat exchange flow path 105 to enable heat exchange between the first heat exchange flow path 105 and the second heat exchange flow path 203, so that the air output end 2031 can output air with a lower temperature, and can also remind the user at the same time.

[0092] When the first heat exchange flow path 105 is running, the temperature sensing component detects that the air temperature before entering the air inlet of the nitrogen oxide separator 202 is still high. At this time, the cooling power of the first heat exchange flow path 105 needs to be increased. At this time, the controller controls and adjusts the opening of the first throttle valve 103 and the second throttle valve 104, thereby increasing the cooling power of the first heat exchange flow path 105 to increase the cooling rate of the second heat exchange flow path 203, so that the air output end 2031 can continuously and stably output air with a lower temperature, and can also remind the user at the same time.

[0093] When the temperature sensing element detects that the air temperature before entering the air inlet of the nitrogen oxide separator 202 is appropriate, the data signal is fed back to the controller. The controller controls and adjusts the opening of the first throttle valve 103 and the second throttle valve 104 to maintain or reduce the cooling power of the first heat exchange flow path 105, so as to achieve the effect of reducing the energy consumption of the air conditioner.

[0094] By arranging a temperature sensing element between the air output end 2031 and the air inlet of the nitrogen oxygen separator 202, the oxygen-generating air conditioner can adjust the opening of the first throttle valve 103 and the second throttle valve 104 to achieve the goal of reducing energy consumption while enabling the air output end 2031 to continuously and stably output air at a lower temperature.

[0095] Optionally, in an implementation of this embodiment, as Figure 3-7 As shown,

[0096] The nitrogen and oxygen separator 202 is a molecular sieve.

[0097] In this embodiment, the nitrogen oxygen separator 202 is a molecular sieve, which has holes and channels with molecular-level and uniform pore sizes. In terms of structure, there are many channels with uniform pore sizes and neatly arranged holes. Molecular sieves with different pore sizes can separate molecules of different sizes and shapes. Molecular sieves have strong adsorption capacity, especially reversible adsorption of water, gas and liquid, so that gas separation and purification can be achieved. The specific process of molecular sieves producing oxygen from air is well known to those skilled in the art and will not be repeated here.

[0098] Embodiment 2

[0099] like Figure 8 As shown, this embodiment provides an oxygen production control method, which is applied to the oxygen production air conditioner in the first embodiment.

[0100] The oxygen production control method comprises:

[0101] According to the relationship between the temperature of the air entering the nitrogen oxide separator 202 and the target temperature threshold, the first throttle valve 103 and / or the second throttle valve 104 are controlled to make the air temperature lower than the target temperature threshold.

[0102] Specifically, Fig. 9 As shown, the oxygen production control method includes:

[0103] According to the relationship between the air temperature value before the air inlet entering the nitrogen oxide separator 202 and the target temperature threshold, controlling the first throttle valve 103 and / or the second throttle valve 104 to make the air temperature value lower than the target temperature threshold comprises:

[0104] If the air temperature value is lower than the target temperature threshold, the openings of the first throttle valve 103 and the second throttle valve 104 are kept unchanged;

[0105] If the air temperature value is higher than or equal to the target temperature threshold, the opening of the first throttle valve 103 and / or the second throttle valve 104 is adjusted to reduce the temperature of the first heat exchange path 105, and the temperature of the first heat exchange path 105 is lower than the temperature of the second heat exchange path 203, so that the air temperature value is lower than the target temperature threshold.

[0106] In this embodiment, the steps of the oxygen production control method include: obtaining the air temperature value before the air inlet entering the nitrogen oxygen separator 202 by the temperature sensing component, the temperature sensing component feeds back the data signal of the temperature value to the controller, and the controller determines whether the air temperature value is lower than the target temperature threshold. If the air temperature value is lower than the target temperature threshold, it means that the temperature of the first heat exchange flow path 105 at this time is sufficient to effectively cool the second heat exchange flow path 203, so that its temperature is lower than the target temperature threshold, thereby ensuring that the air temperature entering the nitrogen oxygen separator 202 is suitable for oxygen production by the nitrogen oxygen separator 202, and the controller controls the opening of the first throttle valve 103 and the second throttle valve 104 to remain unchanged, and maintains this state, that is, the oxygen output by the nitrogen oxygen separator can be continuously and stably maintained within the concentration range required by the user, thereby improving the oxygen production efficiency of the oxygen-producing air conditioner. If the air temperature value is higher than or equal to the target temperature threshold, it indicates that the temperature of the air compressed by the air compressor 201 is still relatively high and is not suitable for entering the nitrogen oxygen separator 202. At this time, the controller can adjust and control the opening of the first throttle valve 103 or the opening of the second throttle valve 104, or adjust and control the openings of the first throttle valve 103 and the second throttle valve 104 at the same time, thereby increasing the refrigeration power of the first heat exchange flow path 105 and further reducing the temperature of the first heat exchange flow path 105 to increase the cooling rate of the second heat exchange flow path 203, so that the air temperature value is lower than the target temperature threshold, thereby ensuring that the air temperature entering the nitrogen oxygen separator 202 is suitable for oxygen production by the nitrogen oxygen separator 202.

[0107] Through the oxygen production control method, it is possible to reduce energy consumption while enabling the air output end 2031 to continuously and stably output air with a lower temperature, thereby improving the oxygen production efficiency of the oxygen-producing air conditioner.

[0108] Embodiment 3

[0109] This embodiment provides an electronic device,

[0110] a memory for storing one or more computer executable instructions;

[0111] The processor is used to call and execute the computer executable instructions in the memory, so as to implement the oxygen production control method of the second embodiment.

[0112] In this embodiment, the electronic device can be implemented to obtain the air temperature value before the air inlet entering the nitrogen oxygen separator 202 by the temperature sensing component, and the temperature sensing component feeds back the data signal of the temperature value to the controller, and the controller determines whether the air temperature value is lower than the target temperature threshold. If the air temperature value is lower than the target temperature threshold, it means that the temperature of the first heat exchange flow path 105 at this time is sufficient to effectively cool the second heat exchange flow path 203, so that its temperature is lower than the target temperature threshold, thereby ensuring that the air temperature entering the nitrogen oxygen separator 202 is suitable for oxygen production by the nitrogen oxygen separator 202, and the controller controls the opening of the first throttle valve 103 and the second throttle valve 104 to remain unchanged, and maintains this state, that is, the oxygen output by the nitrogen oxygen separator can be continuously and stably maintained within the concentration range required by the user, thereby improving the oxygen production efficiency of the oxygen-producing air conditioner. If the air temperature value is higher than or equal to the target temperature threshold, it indicates that the temperature of the air compressed by the air compressor 201 is still high and is not suitable for entering the nitrogen oxygen separator 202. At this time, the controller can adjust and control the opening of the first throttle valve 103 or the opening of the second throttle valve 104, or adjust and control the opening of the first throttle valve 103 and the second throttle valve 104 at the same time, so as to increase the refrigeration power of the first heat exchange flow path 105, so that the temperature of the first heat exchange flow path 105 is further reduced, so as to increase the cooling speed of the second heat exchange flow path 203, so that the air temperature value is lower than the target temperature threshold, thereby ensuring that the air temperature entering the nitrogen oxygen separator 202 is suitable for oxygen production by the nitrogen oxygen separator 202. The electronic device can realize that the air output end 2031 can continuously and stably output air with a lower temperature while reducing energy consumption, thereby improving the oxygen production efficiency of the oxygen-producing air conditioner.

[0113] In summary, the ingenious conception of the oxygen-generating air conditioner and the oxygen-generating control method is:

[0114] First, by setting up a heat exchange between the first heat exchange flow path of the main unit and the second heat exchange flow path of the oxygen production unit, the first heat exchange flow path can reduce the temperature of the air in the second heat exchange flow path before entering the nitrogen and oxygen separator by means of close contact or air medium, thereby reducing the possibility of a reduction in the efficiency of the nitrogen and oxygen separator in separating air, and there is no need to add additional cooling equipment between the air compressor and the nitrogen and oxygen separator. The throttle valve assembly is set to a double throttling mode, which can utilize the low-temperature refrigerant in the middle section of the throttle valve assembly to exchange heat with the air before entering the nitrogen and oxygen separator, thereby reducing the air temperature output by the air compressor, so that the oxygen output by the nitrogen and oxygen separator can be continuously and stably maintained within the concentration range required by the user, thereby improving the oxygen production efficiency of the oxygen-generating air conditioner.

[0115] Second, by arranging a heat exchange component, the first heat exchange path and the second heat exchange path can perform heat exchange in the surrounding cavity, thereby reducing the heat exchange space of the first heat exchange path and the second heat exchange path, and reducing the risk of ineffective heat exchange between the first heat exchange path and the second heat exchange path due to contact with the external air, thereby improving the heat exchange efficiency between the first heat exchange path and the second heat exchange path.

[0116] Third, by arranging the heat exchange element between the air compressor and the nitrogen oxide separator, the lengths of the first heat exchange flow path and the second heat exchange flow path can be shortened, thereby reducing the volume of the oxygen production unit by reducing the occupation of the installation space.

[0117] Fourth, by setting a temperature sensing element between the air input end and the air inlet of the nitrogen oxygen separator, the oxygen-generating air conditioner adjusts the opening of the first throttle valve and the second throttle valve to achieve the goal of reducing energy consumption while enabling the air output end to continuously and stably output air at a lower temperature.

[0118] Fifth, through the oxygen production control method, it is possible to reduce energy consumption while enabling the air output end to continuously and stably output air with a lower temperature, thereby improving the oxygen production efficiency of the oxygen-producing air conditioner.
