Technical Field

[0002] Currently, people often live in enclosed environments, often leading to low indoor oxygen levels. This has led to the emergence of various room oxygenation devices. For example, one approach involves using a specialized oxygen concentrator to extract purified air and deliver it indoors while exhausting the exhaust gas outdoors. Another approach involves using a fresh air system to exchange indoor and outdoor air for oxygenation. However, existing oxygenation devices experience significant temperature fluctuations in different regions and seasons, which can affect the amount of oxygen they deliver.

[0079] In order to enable a more detailed understanding of the features and technical contents of the embodiments of the present application, the implementation of the embodiments of the present application is described in detail below with reference to the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present application.

[0080] In an embodiment of the present application, a method for controlling an air conditioner is provided, which is applied to an air conditioner. For example, Figure 1 The air conditioner 10 includes an oxygen production module 101 and a fresh air module 102. The fresh air module 102 includes an external circulation module 1021 and an internal circulation module 1022. The oxygen production module 101 has an oxygen production function. The fresh air module 102 has air intake modes including external circulation, internal and external circulation, and internal circulation. Specifically, the external circulation mode means that the air inlet of the fresh air duct is the air inlet of the external circulation module 1021. The internal circulation mode means that the air inlet of the fresh air duct is the air inlet of the internal circulation module 1022. The internal and external circulation mode means that the air inlet of the fresh air duct is the air inlet of both the external circulation module 1021 and the internal circulation module 1022, and indoor and outdoor air is simultaneously injected into the fresh air duct.

[0081] In practical applications, air conditioners can be wall-mounted, floor-standing, window, or ceiling-mounted. Floor-standing air conditioners have both upwind and downwind ducts. Due to the internal structural features of some floor-standing air conditioners, the oxygen generator module can be installed in the upwind duct.

[0082] like Figure 2As shown, the upwind duct (i.e., the air outlet side) includes the oxygen production module, the HEPA filter of the fresh air module and other purification modules and the air outlet, and the downwind duct (i.e., the air inlet side) includes the fresh air module in sequence along the air inlet direction: fresh air / outdoor air inlet, fresh air inlet valve 1, indoor air inlet, indoor air inlet valve 3, internal and external circulation switching valve 2, heating module and centrifugal fan. When external circulation is used to intake air, the indoor air inlet valve 3 is closed, the fresh air inlet valve 1 is opened, and the internal and external circulation switching valve 2 is opened. The fresh air / outdoor air passes through the fresh air inlet valve 1 and the internal and external circulation switching valve 2 and then enters the centrifugal fan and oxygen generator; when internal and external circulation is used to intake air, the indoor air inlet valve 3 is opened, the fresh air inlet valve 1 is opened, and the internal and external circulation switching valve 2 is opened. The fresh air / outdoor air passes through the fresh air inlet valve 1 and the internal and external circulation switching valve 2 and then mixes with the indoor air entering through the indoor air inlet valve 3 and then enters the centrifugal fan and oxygen generator module; when internal circulation is used to intake air, the indoor air inlet valve 3 is opened, the fresh air inlet valve 1 is closed, and the internal and external circulation switching valve 2 is closed. The indoor air enters the centrifugal fan and oxygen generator module through the indoor air inlet valve 3.

[0083] For example, in some embodiments, the oxygen production module 101 includes a filter (for performing secondary filtration on the air input from the air inlet), an air intake silencer, an air compressor, a molecular sieve and its control valve, a pressure regulating valve, an exhaust silencer and other components.

[0084] like Figure 3 As shown, the oxygen production module 101 may include an air inlet, an oxygen outlet, a nitrogen outlet, and a power supply control port. The air inlet of the oxygen production module 101 is connected to the air inlet of the fresh air duct via a pipe and a valve, the oxygen outlet of the oxygen production module 101 is connected to the air outlet of the fresh air duct via a pipe, and the nitrogen outlet of the oxygen production module is connected to the outside of the room via a separate pipe.

[0085] For example, the oxygen production module can be implemented based on pressure swing adsorption (PSA) oxygen production technology. The basic principle of PSA oxygen production technology is to use the difference in adsorption performance of nitrogen and oxygen in the air on zeolite molecular sieve (ZMS) due to different pressures to selectively adsorb and separate nitrogen and oxygen, that is, to adsorb nitrogen and other impurities to produce oxygen.

[0086] Based on the above air conditioner, the embodiment of the present application provides an air conditioner control method. Figure 4 FIG. 1 is a first flow chart of the air conditioner control method according to an embodiment of the present application. Figure 4 As shown, the method may specifically include:

[0087] Step 401: Control the fresh air module to execute the first fresh air strategy, and the oxygen production module to execute the first oxygen production strategy;

[0088] Here, the first fresh air strategy may be a fresh air strategy executed when the air conditioner is started. Exemplarily, the first fresh air strategy may be a pre-set initial fresh air strategy, for example, wherein the first fresh air strategy includes an external circulation air intake mode, the heating module is in an off state, and the centrifugal fan has a maximum speed. The oxygen production capacity of the oxygen production module is maximized when the first fresh air strategy is used.

[0089] The first fresh air strategy can also be a user-defined fresh air strategy. For example, when the air conditioner is started for cooling, the first fresh air strategy includes internal and external circulation air intake mode, the heating module is in the off state, and the centrifugal fan speed is the maximum speed; when the air conditioner is started for heating, the first fresh air strategy includes internal and external circulation air intake mode, the heating module is in the off state, and the centrifugal fan speed is the maximum speed.

[0090] The first fresh air strategy can also be understood as the fresh air strategy being executed by the air conditioner.

[0091] Here, the first oxygen production strategy can be the oxygen production strategy executed when the air conditioner is started or the oxygen production strategy currently being executed by the air conditioner. The oxygen production strategy includes the speed of the air compressor, and the first oxygen production strategy includes setting the air compressor speed to the maximum speed. In actual applications, the oxygen production module can continuously use the first oxygen production strategy to perform oxygen production operations, or adjust the speed according to the temperature of the air compressor during the oxygen production process.

[0092] Step 402: Obtain a first temperature value at a first position in the fresh air duct; wherein the first position is a position of the fresh air duct located after the heating module along the air inlet direction;

[0093] like Figure 2 As shown, the first position is between the heating module and the centrifugal fan. Specifically, a temperature sensor is installed at the junction of the centrifugal fan and the adding module to detect the air temperature. This means that depending on the air intake method, the first temperature value (Tnew) can be one of three types: the literal fresh air temperature (outdoor air temperature), but also specifically includes the indoor and outdoor mixed air temperature and the indoor air temperature.

[0094] After passing through the heating module and centrifugal fan, the air is fed into the oxygen production module, which then produces oxygen. Therefore, the air temperature at the first location affects the oxygen production efficiency of the oxygen production module. When the air temperature at the first location is low, the air temperature needs to be increased; when the air temperature at the first location is high, the air temperature needs to be decreased to maintain the air temperature within a suitable temperature range. Within this suitable temperature range, the oxygen production efficiency of the oxygen production module is minimally affected, and the fresh air effect of the fresh air module is also minimally affected.

[0095] Step 403: Determine whether the first temperature value is greater than or equal to the first temperature threshold and less than or equal to the second temperature threshold; if yes, execute step 404; if not, execute step 405;

[0096] Here, the first temperature value is greater than or equal to the first temperature threshold (T1) and less than or equal to the second temperature threshold (T2), so that the centrifugal fan in the fresh air module and the air compressor in the oxygen production module can operate at the maximum speed as much as possible.

[0097] For example, the value of T1 is taken into consideration when outdoor air enters the fresh air duct during external circulation at low temperature. Since the fresh air duct contains purification modules such as HEPA nets, and there are tiny particles on the purification modules, the fresh air duct may be frozen, so the lower limit low temperature is set accordingly.

[0098] T2 is the maximum ambient temperature allowed when outdoor air enters the fresh air duct during external circulation, the centrifugal fan runs at the highest speed, and the centrifugal fan heat test passes.

[0099] Step 404: Control the fresh air module to continue executing the first fresh air strategy;

[0100] That is to say, if the first temperature value is within the appropriate temperature range when the fresh air module executes the first fresh air strategy, there is no need to adjust the fresh air strategy; if the first temperature value is outside the appropriate temperature range, the fresh air strategy needs to be adjusted so that the first temperature value is back within the appropriate temperature range.

[0101] Step 405: Determine a second fresh air strategy according to the first temperature value, and control the fresh air module to execute the second fresh air strategy.

[0102] Here, the second fresh air strategy can be understood as a fresh air strategy redefined based on the first temperature value. Based on the pre-set correspondence between temperature values ​​and fresh air strategies, the second fresh air strategy corresponding to the current first temperature value can be determined. The second fresh air strategy can adjust the first temperature value of the first position or adjust the centrifugal fan speed to ensure normal operation of the centrifugal fan in high-temperature environments.

[0103] Exemplarily, in some embodiments, determining the second fresh air strategy based on the first temperature value includes: determining the first temperature range in which the first temperature value is located; determining the second fresh air strategy based on the first temperature range and a preset first mapping relationship; wherein the first mapping relationship includes a mapping relationship between the temperature range and the second fresh air strategy, and the second fresh air strategy includes the air intake method of the fresh air module and the working status of the heating module.

[0104] Exemplarily, the fresh air module includes an external circulation module and an internal circulation module, and the air intake mode of the fresh air module includes an external circulation air intake mode, an internal and external circulation air intake mode, and an internal circulation air intake mode; the working state of the heating module includes a heating state and a closed state.

[0105] Exemplarily, the first mapping relationship includes:

[0106] When the first temperature value is greater than or equal to the first temperature threshold and less than or equal to the second temperature threshold, the corresponding fresh air strategy includes an external circulation air intake mode and the heating module is in a closed state;

[0107] When the first temperature value is less than the first temperature threshold, the corresponding fresh air strategy includes an external circulation air intake mode and the heating module is in a heating state;

[0108] When the first temperature value is greater than the second temperature threshold, the corresponding fresh air strategy includes an internal and external circulation air intake mode and the heating module is in a closed state.

[0109] Exemplarily, in some embodiments, the fresh air strategy further includes the rotation speed of the centrifugal fan;

[0110] Accordingly, the first mapping relationship includes:

[0111] When the first temperature value is greater than or equal to the first temperature threshold and less than or equal to the second temperature threshold, the corresponding fresh air strategy includes an external circulation air intake mode, the heating module is in an off state, and the speed of the centrifugal fan is a first speed;

[0112] When the first temperature value is less than the first temperature threshold, the corresponding fresh air strategy includes an external circulation air intake mode, the heating module is in a heating state, and the speed of the centrifugal fan is a first speed;

[0113] When the first temperature value is greater than the second temperature threshold and less than or equal to the third temperature threshold, the corresponding fresh air strategy includes an external circulation air intake mode, the heating module is in the off state, and the speed of the centrifugal fan is the second speed;

[0114] When the first temperature is greater than the third temperature threshold, the corresponding fresh air strategy includes an internal and external circulation air intake mode, a heating mode being off, and a centrifugal fan speed being a third speed;

[0115] The first speed is greater than the second speed, and the second speed is greater than or equal to the third speed. In other words, in a high-temperature environment, the air conditioner can reduce the speed of the centrifugal fan in the fresh air module to ensure normal operation. Similarly, the speed of the air conditioner compressor in the oxygen production module can be reduced to ensure normal operation.

[0116] In actual applications, the oxygen addition capacity of the oxygen production modules corresponding to different fresh air strategies is arranged from high to low:

[0117] External circulation air intake + fresh air load maximum speed operation + oxygen generator compressor maximum speed operation;

[0118] External circulation air intake + fresh air load running at the highest speed + oxygen generator compressor running at a lower speed;

[0119] External circulation air intake + fresh air load running at a low speed + oxygen generator compressor running at a low speed;

[0120] Internal and external circulation air intake + fresh air load maximum speed operation + oxygen generator compressor maximum speed operation;

[0121] Internal and external circulation air intake + fresh air load running at the highest speed + oxygen generator compressor running at a lower speed;

[0122] Internal circulation air intake + oxygen generator compressor runs at the highest speed.

[0123] Exemplarily, in some embodiments, after controlling the fresh air module to execute the second fresh air strategy, the method further includes:

[0124] After a preset delay time, the fresh air module is controlled to execute the third fresh air strategy; or

[0125] Obtaining a second temperature value at a second position in the fresh air duct; wherein the second position is the position of the air inlet of the external circulation module;

[0126] The second temperature value is greater than or equal to the first temperature threshold and less than or equal to the second temperature threshold, and the fresh air module is controlled to execute the third fresh air strategy;

[0127] Among them, the third fresh air strategy includes external circulation air intake mode, the heating module is in the off state, and the speed of the centrifugal fan is the maximum speed.

[0128] It should be noted that since external circulation is the optimal air intake method, after the air conditioner has been running for a period of time, the outdoor ambient temperature value, i.e., the second temperature value, is collected. Based on this second temperature value, it is determined whether external circulation can be selected to optimize the fresh air and oxygen production effects of the air conditioner. The third fresh air strategy can also be the fresh air strategy executed when the air conditioner is started.

[0129] By adopting the above technical solution, when the working environment temperature of the air conditioner is too low or too high, the fresh air strategy is adjusted to make the temperature of the air entering the fresh air channel within the appropriate temperature range, so that the centrifugal fan in the fresh air module and the air compressor in the oxygen production module can operate at the maximum speed as much as possible, so that the air conditioner maintains a high oxygen enrichment volume, ensures the oxygen enrichment effect, and reduces the impact of the ambient temperature on the oxygen enrichment effect of the air conditioner.

[0130] In order to better reflect the purpose of this application, further examples are given based on the above embodiments of this application. Figure 5 As shown, the method specifically includes:

[0131] Step 501: Control the fresh air module to execute the first fresh air strategy, and the oxygen production module to execute the first oxygen production strategy;

[0132] Here, the fresh air strategy includes the air intake method of the fresh air module and the working status of the heating module.

[0133] Exemplarily, the fresh air module includes an external circulation module and an internal circulation module, and the air intake mode of the fresh air module includes an external circulation air intake mode, an internal and external circulation air intake mode, and an internal circulation air intake mode; the working state of the heating module includes a heating state and a closed state.

[0134] The fresh air strategy also includes the speed of the centrifugal fan.

[0135] Step 502: Acquire a first temperature value at a first position in the fresh air duct; wherein the first position is a position of the fresh air duct located after the heating module along the air inlet direction;

[0136] like Figure 2 As shown, the first position is the position between the heating module and the centrifugal fan.

[0137] Step 503: Determine whether the first temperature value is greater than or equal to the first temperature threshold and less than or equal to the second temperature threshold; if yes, execute step 504; if not, execute step 505;

[0138] Here, the appropriate temperature range is greater than or equal to the first temperature threshold ( T1 ) and less than or equal to the second temperature threshold ( T2 ).

[0139] For example, the value of T1 is taken into consideration when outdoor air enters the fresh air duct during external circulation at low temperature. Since the fresh air duct contains purification modules such as HEPA nets, and there are tiny particles on the purification modules, the fresh air duct may be frozen, so the lower limit low temperature is set accordingly.

[0140] T2 is the maximum ambient temperature allowed when outdoor air enters the fresh air duct during external circulation, the centrifugal fan runs at the highest speed, and the centrifugal fan heat test passes.

[0141] Step 504: Control the fresh air module to continue executing the first fresh air strategy;

[0142] Step 505: When the first temperature value is less than the first temperature threshold, the execution time is obtained; and a second fresh air strategy is determined according to the first temperature value, the execution time, and the first mapping relationship.

[0143] Here, the execution time refers to the time the air conditioner is currently executing the fresh air strategy. The execution time is used to determine whether the fresh air strategy is effective, that is, whether it can control the first temperature value within the appropriate temperature range. If effective, the strategy continues to be executed; if not, a new fresh air strategy is determined.

[0144] Exemplarily, the first mapping relationship includes:

[0145] When the first temperature value is greater than or equal to the first temperature threshold and less than or equal to the second temperature threshold, the corresponding fresh air strategy includes an external circulation air intake mode and the heating module is in a closed state;

[0146] When the first temperature value is less than the first temperature threshold, the corresponding fresh air strategy includes an external circulation air intake mode and the heating module is in a heating state;

[0147] When the first temperature value is less than the first temperature threshold and the execution time is greater than the first duration, the corresponding fresh air strategy includes an internal and external circulation air intake mode and the heating module is in a heating state;

[0148] When the first temperature value is less than the first temperature threshold and the execution time is greater than the second duration, the corresponding fresh air strategy includes an internal circulation air intake mode and the heating module is in a heating state; here, the second duration is equal to or different from the first duration.

[0149] When the first temperature value is greater than the second temperature threshold, the corresponding fresh air strategy includes an internal and external circulation air intake mode and the heating module is in a closed state.

[0150] That is to say, when the first temperature value is lower than the first temperature threshold, if the second fresh air strategy is invalid after being executed for the first period of time, the external circulation air intake mode will be switched to the internal and external circulation air intake mode. Furthermore, if it is still invalid after being delayed for the second period of time, the internal and external circulation air intake mode will be switched to the internal circulation air intake mode.

[0151] That is to say, when the air conditioner is working in a low-temperature environment, the fresh air volume is adjusted by changing the air intake method to reduce the impact of the outdoor air temperature. Turning on the heating module can increase the air temperature in the fresh air channel, thereby avoiding freezing in the fresh air channel and affecting the normal fresh air function, and avoiding further affecting the oxygen production function of the oxygen production module.

[0152] Step 506: Control the fresh air module to execute the second fresh air strategy;

[0153] In actual applications, if the first fresh air strategy includes an external circulation air intake mode, the heating module is in a closed state, and the speed of the centrifugal fan is the maximum speed.

[0154] The second fresh air strategy includes an external circulation air intake mode, the heating module is in a heating state, and the speed of the centrifugal fan is the maximum speed.

[0155] When the first temperature value is less than the first temperature threshold, the heating module is started to heat the air in the fresh air duct, and the air intake mode and the speed of the centrifugal fan remain unchanged.

[0156] It should be noted that in the process of controlling the fresh air module to execute the second fresh air strategy, the first temperature value of the first position continues to be monitored. If after a period of execution, the execution of the second fresh air strategy cannot raise the temperature to an appropriate temperature range, steps 503 to 506 can be re-executed according to the latest first temperature value to reselect the fresh air strategy.

[0157] Steps 503 to 506 are re-executed according to the latest first temperature value, and step 504 can be replaced by controlling the fresh air module to continue to execute the second fresh air strategy.

[0158] By adopting the above technical solution, when the air conditioner is working in a low temperature environment, the fresh air strategy is adjusted to increase the temperature of the air entering the fresh air duct, thereby preventing freezing in the fresh air duct from affecting the normal fresh air function, avoiding further affecting the oxygen production function of the oxygen production module, and reducing the impact of the ambient temperature on the oxygen enrichment effect of the air conditioner.

[0159] In order to better reflect the purpose of this application, further examples are given based on the above embodiments of this application. Figure 6 As shown, the method specifically includes:

[0160] Step 601: Control the fresh air module to execute the first fresh air strategy, and the oxygen production module to execute the first oxygen production strategy;

[0161] Step 602: Acquire a first temperature value at a first position in the fresh air duct; wherein the first position is a position of the fresh air duct after the heating module along the air inlet direction;

[0162] Step 603: Determine whether the first temperature value is greater than or equal to the first temperature threshold and less than or equal to the second temperature threshold; if yes, execute step 604; if not, execute step 605;

[0163] Step 604: Control the fresh air module to continue executing the first fresh air strategy;

[0164] Step 605: When the first temperature value is greater than the second temperature threshold, the execution time is obtained; and the second fresh air strategy is determined according to the first temperature value, the execution time, and the first mapping relationship;

[0165] Here, the execution time refers to the time the air conditioner is currently executing the fresh air strategy. The execution time is used to determine whether the fresh air strategy is effective, that is, whether it can control the first temperature value within the appropriate temperature range. If effective, the strategy continues to be executed; if not, a new fresh air strategy is determined.

[0166] Exemplarily, the first mapping relationship includes:

[0167] When the first temperature value is greater than or equal to the first temperature threshold and less than or equal to the second temperature threshold, the corresponding fresh air strategy includes an external circulation air intake mode and the heating module is in a closed state;

[0168] When the first temperature value is less than the first temperature threshold, the corresponding fresh air strategy includes an external circulation air intake mode and the heating module is in a heating state;

[0169] When the first temperature value is greater than the second temperature threshold, the corresponding fresh air strategy includes internal and external circulation air intake mode and the heating module is in the off state;

[0170] When the first temperature value is greater than the second temperature threshold and the execution time is greater than the third time period, the corresponding fresh air strategy includes an internal and external circulation air intake mode and the heating module is in a closed state;

[0171] When the first temperature value is greater than the second temperature threshold and the execution time is greater than the fourth time period, the corresponding fresh air strategy includes an internal circulation air intake mode and the heating module is in the off state. Here, the third time period and the fourth time period are equal or different.

[0172] That is, when the first temperature value is greater than the second temperature threshold, if the second fresh air strategy is ineffective after the third time period, the external circulation air intake mode will be switched to the internal and external circulation air intake mode. Furthermore, if it is still ineffective after the fourth time period, the internal and external circulation air intake mode will be switched to the internal circulation air intake mode. This effectively reduces the air temperature at the first position, allowing the centrifugal fan in the fresh air module to operate at the maximum speed possible, ensuring the fresh air effect and avoiding centrifugal fan failure caused by the centrifugal fan operating in a high temperature environment. It can also enable the air compressor in the oxygen production module to operate at the maximum speed possible to ensure the oxygen production volume.

[0173] Step 606: Control the fresh air module to execute the second fresh air strategy;

[0174] In actual applications, if the first fresh air strategy includes an external circulation air intake mode, the heating module is in a closed state, and the speed of the centrifugal fan is the maximum speed.

[0175] The second fresh air strategy includes internal and external circulation air intake mode, the heating module is in the off state and the speed of the centrifugal fan is the maximum speed.

[0176] When the first temperature value is greater than the second temperature threshold, the air intake mode is switched to the internal and external circulation air intake mode.

[0177] It should be noted that while controlling the fresh air module to execute the second fresh air strategy, the first temperature value of the first position continues to be monitored. If, after a period of execution, the execution of the second fresh air strategy fails to raise the temperature to a suitable temperature range, steps 603 to 606 can be re-executed based on the latest first temperature value to reselect the fresh air strategy.

[0178] Steps 603 to 606 are re-executed according to the latest first temperature value, and step 604 can be replaced by controlling the fresh air module to continue to execute the second fresh air strategy.

[0179] By adopting the above technical solution, when the air conditioner is operating in a high-temperature environment, the temperature of the air entering the fresh air duct is lowered by adjusting the fresh air strategy, so that the centrifugal fan in the fresh air module can operate at the maximum speed as much as possible, the amount of fresh air delivered to the room by the fresh air module is maintained at a high level, the air compressor in the oxygen production module can operate at the maximum speed as much as possible, and the oxygen production amount of the oxygen production module is maintained at a high level. Overall, the air conditioner maintains a high oxygen addition amount to the room, ensures the oxygen addition effect, and reduces the influence of the ambient temperature on the oxygen addition effect of the air conditioner.

[0180] On the basis of the above embodiment, the fresh air strategy corresponding to the fresh air module is also related to the current working mode of the air conditioner. For example, when the air conditioner is in cooling mode, the heating module can also be turned off; when the air conditioner is in heating mode, the heating module can be turned on or off. The following further illustrates the air conditioner control method of the embodiment of the present application in combination with the working mode of the air conditioner. Figure 7 As shown, the air conditioner control method may specifically include:

[0181] Step 701: Control the fresh air module to execute the first fresh air strategy, and the oxygen production module to execute the first oxygen production strategy;

[0182] Step 702: Obtain a first temperature value at a first position in the fresh air duct; wherein the first position is a position of the fresh air duct after the heating module along the air inlet direction;

[0183] Step 703: Determine whether the first temperature value is greater than or equal to the first temperature threshold and less than or equal to the second temperature threshold; if yes, execute step 704; if not, execute step 705;

[0184] Step 704: Control the fresh air module to continue executing the first fresh air strategy;

[0185] Step 705: When the first temperature value is less than the first temperature threshold, the heating gear of the air conditioner is obtained; and a second fresh air strategy is determined according to the first temperature value, the heating gear, and the first mapping relationship.

[0186] Exemplarily, in some embodiments, the first mapping relationship further includes: the first temperature value is less than the first temperature threshold, and the heating gear of the air conditioner is the highest gear, and the corresponding fresh air strategy includes an internal circulation air intake mode and the heating module is in the off state;

[0187] The first temperature value is less than the first temperature threshold, and the heating gear of the air conditioner is not the highest gear. The corresponding fresh air strategy includes internal circulation air intake mode, the heating module is in the off state, and the heating gear is adjusted to the highest gear.

[0188] In practical applications, when determining the second fresh air strategy, the execution time of the fresh air strategy being executed by the air conditioner may also be considered, that is, the second fresh air strategy is determined based on the first temperature value, heating gear, execution time and first mapping relationship.

[0189] Step 706: When the first temperature value is greater than the second temperature threshold, the cooling gear of the air conditioner is obtained; and a second fresh air strategy is determined according to the first temperature value, the cooling gear, and the first mapping relationship.

[0190] Exemplarily, in some embodiments, the first mapping relationship further includes: the first temperature value is greater than the second temperature threshold, and the cooling gear of the air conditioner is the highest gear, and the corresponding fresh air strategy includes an internal circulation air intake mode and the heating module is in the off state;

[0191] The first temperature value is greater than the second temperature threshold, and the cooling gear of the air conditioner is not the highest gear. The corresponding fresh air strategy includes internal circulation air intake mode, the heating module is in the off state, and the cooling gear is adjusted to the highest gear.

[0192] In practical applications, when determining the second fresh air strategy, the execution time of the fresh air strategy being executed by the air conditioner may also be considered, that is, the second fresh air strategy is determined based on the first temperature value, heating gear, execution time and first mapping relationship.

[0193] Step 707: Control the fresh air module to execute the second fresh air strategy.

[0194] Based on the above embodiments of the present application, further examples are given, such as Figure 8 As shown, the method further includes adjusting the speed of the air compressor in the oxygen production module according to the temperature value of the air compressor, specifically including:

[0195] Step 801: Acquire a third temperature value of an air compressor of an oxygen production module;

[0196] Step 802: Determine whether the third temperature value is greater than or equal to the fourth temperature threshold and less than or equal to the fifth temperature threshold; if yes, execute step 803; if not, execute step 804;

[0197] Step 803: Control the oxygen production module to continue to execute the first oxygen production strategy;

[0198] Step 804: Determine a second oxygen production strategy according to the third temperature value, and control the oxygen production module to execute the second oxygen production strategy.

[0199] Here, the second oxygen production strategy is used to adjust the air compressor speed in a high temperature environment to ensure the normal operation of the air compressor

[0200] Exemplarily, in some embodiments, determining the second oxygen production strategy based on the third temperature value includes: determining a second temperature range in which the second temperature value is located; and determining the second oxygen production strategy based on the second temperature range and a second mapping relationship; wherein the second mapping relationship includes a mapping relationship between temperature ranges and second oxygen production strategies, and the second oxygen production strategy includes a speed of an air compressor in the oxygen production module.

[0201] It should be noted that different air compressors have different temperature ranges corresponding to different speeds. For example, the air compressor temperature is divided into three temperature ranges:

[0202] Temperature range 1, corresponding to the first speed;

[0203] Temperature range 2, corresponding to the second speed;

[0204] Temperature range 3, corresponding to the third speed;

[0205] If temperature range 1 is lower than temperature range 2, and temperature range 2 is lower than temperature range 3, and if temperature range 1 is the optimal operating range of the air compressor, when the temperature of the air compressor increases from temperature range 1 to temperature range 2, the speed is reduced from the first speed to the second speed, and when the temperature increases from temperature range 2 to temperature range 3, the speed is reduced from the second speed to the third speed.

[0206] In some embodiments, the second mapping relationship can be set as a temperature-speed mapping relationship table, and the current optimal speed of the air compressor is determined by searching the mapping relationship table based on the third temperature value of the air compressor. In other embodiments, the second mapping relationship can be set as a temperature-speed conversion formula, and the current optimal speed of the air compressor is determined by calculation.

[0207] In other embodiments, the method may further include: when the first temperature value is greater than or equal to a first temperature threshold and less than or equal to a second temperature threshold, determining a second oxygen production strategy based on the first temperature value. In other words, since the air temperature at the first location directly affects the operating temperature of the oxygen production module's air compressor, the first temperature value at the first location may also be used as a basis for adjusting the air conditioning compressor. For example, if the first temperature value is greater than the second temperature threshold and less than or equal to a third temperature threshold, the air conditioning compressor speed is reduced from the first speed to the second speed.

[0208] In this way, by reducing the speed of the air compressor in a high temperature environment, the normal operation of the air-conditioning compressor is guaranteed, and the service life of the air-conditioning compressor is increased. In the appropriate temperature range, the air-conditioning compressor can operate at the maximum speed, so that the oxygen production module maintains a high oxygen production capacity, thereby ensuring the oxygen production effect of the air conditioner.

[0209] To reduce noise, the air compressor is installed in the oxygen concentrator module's mounting box. For safety reasons, the driver board is also installed in the mounting box. Due to structural space limitations, the driver board mounting box is installed near the compressor mounting box. The temperature inside the driver board mounting box is easily affected by the compressor's operation. Furthermore, the oxygen concentrator is installed in the air duct, which is affected by the air intake pattern, resulting in variable operating temperature. To adapt the oxygen concentrator to ambient temperature fluctuations, a temperature sensor is installed in the driver board mounting box to monitor the box's temperature. The air compressor speed can be adjusted based on the temperature inside the driver board mounting box, thereby adjusting the oxygen concentrator's oxygen production capacity. Alternatively, a temperature sensor could be installed in the compressor mounting box to adjust the air compressor speed based on both the compressor mounting box and the driver board mounting box's temperature, further increasing the upper limit of the ambient temperature it can adapt to.

[0210] In order to better reflect the purpose of this application, based on the above embodiments of this application, further examples are given for the air conditioning control method in different temperature ranges. Figure 9 As shown, the method specifically includes:

[0211] Step 901: T1≤Tnew≤T2

[0212] Here, Tnew is the first temperature value of the first position, T1 is the first temperature threshold, and T2 is the second temperature threshold.

[0213] For example, the value of T1 is taken into consideration when outdoor air enters the fresh air duct during external circulation at low temperature. Since the fresh air duct contains purification modules such as HEPA nets, and there are tiny particles on the purification modules, the fresh air duct may be frozen, so the lower limit low temperature is set accordingly.

[0214] T2 is the maximum ambient temperature allowed when outdoor air enters the fresh air channel during external circulation air intake, the centrifugal fan operates at the highest speed, and the heat test of the centrifugal fan is qualified.

[0215] Step 902: Maintain external circulation air intake, and the centrifugal fan operates at the maximum speed; control the oxygen enrichment of the oxygen generation module.

[0216] Step 903: After Tn time, turn off the PTC heater, switch the current air intake mode to external circulation air intake, maintain the current speed of the centrifugal fan, and maintain the oxygen enrichment of the oxygen generation module.

[0217] Here, the PTC heater can be understood as the heating module in the above embodiments of the present application.

[0218] As Figure 10 shown, the method specifically includes:

[0219] Step 1001: T2 < Tnew ≤ T3;

[0220] Here, T3 is the third temperature threshold.

[0221] Exemplarily, T3 is the maximum ambient temperature allowed when the centrifugal fan operates at a lower speed during external circulation air intake and the heat test of the centrifugal fan is qualified. At this lower speed, the fresh air volume is not less than the fresh air volume during internal and external circulation air intake.

[0222] Step 1002: Maintain external circulation air intake, look up the table to reduce the operating speed of the centrifugal fan; control the oxygen enrichment of the oxygen generation module.

[0223] Step 1003: After Tn time, turn off the PTC heater, switch the current air intake mode to external circulation air intake, maintain the current speed of the centrifugal fan, and maintain the oxygen enrichment of the oxygen generation module.

[0224] As Figure 11 shown, the method specifically includes:

[0225] Step 1101: Tnew < T1

[0226] Step 1102: Turn on the PTC heater, maintain external circulation air intake within t21 time, and control the oxygen enrichment of the oxygen generation module.

[0227] Step 1103: After t21 time, if Tnew ≥ T1, then maintain external circulation air intake and control the oxygen enrichment of the oxygen generation module.

[0228] Step 1104: After t21 time, if Tnew < T1, switch the external circulation air intake to internal and external circulation air intake, and control the oxygen enrichment of the oxygen generation module.

[0229] Step 1105: After t22 time, if Tnew ≥ T1, then maintain external circulation air intake and control the oxygen enrichment of the oxygen generation module.

[0230] Step 1106: After time t22, when T_new < T1 and at the highest heating gear, switch the fresh air intake of the internal and external circulation to the internal circulation intake, turn off the PTC heater, and control the oxygen enrichment module to increase oxygen;

[0231] Here, in a low-temperature environment, if the air conditioner starts the heating function, the PTC heater can be turned off to save energy consumption. Or the PTC heater can be turned on to improve the heating efficiency.

[0232] Step 1107: After time t22, when T_new < T1 and not at the highest heating gear, adjust the heating gear to the highest, and control the oxygen enrichment module to increase oxygen;

[0233] Step 1108: After time t23, when T_new ≥ T1, maintain the fresh air intake of the internal and external circulation, and control the oxygen enrichment module to increase oxygen;

[0234] Step 1109: After time t23, when T_new < T1, switch the fresh air intake of the internal and external circulation to the internal circulation intake, turn off the PTC heater, and control the oxygen enrichment module to increase oxygen;

[0235] Step 1110: After time Tn, turn off the PTC heater, switch to the external circulation intake, and maintain the oxygen enrichment of the oxygen enrichment module.

[0236] Tn > (t21 + t22 + t23), where Tn is the cycle waiting time for each adjustment of the fresh air strategy, that is, the fresh air strategy needs to be readjusted according to the fresh air (air) temperature every Tn time. Considering the change cycle of the outdoor air temperature, the value of Tn is generally relatively long, such as 30 min, 1 h, 2 h, etc. Times such as t21, t22, and t23 are the waiting stabilization times after each mode switch, and are obtained through actual situation tests.

[0237] [[ID=ZZ]]As Figure 12 shown, the method specifically includes:

[0238] Step 1201: T3 < T_new;

[0239] Step 1202: Turn off the PTC heater, switch the external circulation intake to the fresh air intake of the internal and external circulation, and control the oxygen enrichment module to increase oxygen

[0240] Step 1203: After time t41, when T_new ≤ T2, maintain the fresh air intake of the internal and external circulation, and control the oxygen enrichment module to increase oxygen

[0241] Step 1204: After time t41, when T2 < T_new and at the highest cooling gear, switch to the internal circulation intake, and control the oxygen enrichment module to increase oxygen;

[0242] Step 1205: After time t41, when T2 < T_new and not at the highest cooling gear, adjust the cooling gear to the highest, and control the oxygen enrichment module to increase oxygen;

[0243] Step 1206: After time t42, if T_new ≤ T2, maintain the internal and external circulation air intake, and control the oxygen generation module to increase oxygen.

[0244] Step 1207: After time t42, if T2 < T_new, switch to internal circulation air intake, and control the oxygen generation module to increase oxygen.

[0245] Step 1208: After time Tn, turn off the PTC heater, switch to external circulation air intake, and maintain the oxygen generation of the oxygen generation module.

[0246] Tn > (t41 + t42). Tn is the cycle waiting time for each adjustment of the fresh air strategy, that is, the fresh air strategy needs to be readjusted according to the fresh air (air) temperature every Tn time. Considering the change cycle of the outdoor air temperature, the value of Tn is generally relatively long, such as 30 min, 1 h, 2 h, etc. Times such as t41 and t42 are the waiting stabilization times after each mode switch, which are obtained through actual situation tests.

[0247] ]>It should be noted that for those not clearly stating the centrifugal fan speed above, they can all operate at the highest speed.

[0248] The air compressor of the above oxygen generation module for increasing oxygen can operate at the highest speed, or the speed can be adjusted according to the temperature of the air compressor during the oxygen generation process.
