Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more specifically, to an all-weather adjustment and control method and an air conditioner. Background Technology

[0002] As people's living standards improve, their requirements for indoor air quality when using air conditioning are also gradually increasing. Air conditioners have functions such as air purification, dehumidification, heating, and cooling; the air purification function is generally referred to as the fresh air function.

[0003] Currently, home air conditioners with fresh air functions are becoming increasingly common, providing users with a better experience. The quality of outdoor air and the volume of fresh air entering the room directly determine the freshness of the room's air. However, excessive fresh air volume can affect room thermal comfort, while insufficient fresh air volume weakens the air purification effect. Currently, most fresh air conditioners are user-adjustable, which is highly subjective and leads to unsatisfactory temperature and humidity control and air purification effects, impacting the user experience. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide an all-weather adjustment and control method and an air conditioner, which can improve the current air conditioner's unsatisfactory temperature and humidity control and air purification effects, thus affecting the user experience.

[0006] In a first aspect, embodiments of the present invention provide an all-weather adjustment and control method, applied to an air conditioner, the method comprising:

[0007] When the air conditioner enters the AI ​​fresh air mode, it acquires the outdoor temperature, indoor temperature, and indoor relative humidity, and selects and activates the target operating mode from various operating modes based on the outdoor temperature, indoor temperature, and indoor relative humidity; wherein, the operating modes include cooling mode, heating mode, dehumidification mode, humidification mode, and ventilation mode;

[0027] The first mass is determined based on the TVOC concentration, and the second mass is determined based on the CO2 concentration.

[0028] Indoor air quality is determined based on the first mass and the second mass.

[0029] Furthermore, the step of selecting and activating the fresh air mode under the target operating mode based on the outdoor temperature and / or the indoor air quality includes:

[0030] When the outdoor temperature is greater than a preset second high temperature threshold, or when the outdoor temperature is less than a preset low temperature threshold, the fresh air mode is off by default.

[0031] When the outdoor temperature is between the low temperature threshold and the second high temperature threshold, a fresh air mode is determined based on the indoor air quality.

[0036] When the indoor air quality is at level four, set the fresh air mode to strong mode;

[0037] The air quality represented by the first level, the second level, the third level, and the fourth level deteriorates in that order.

[0038] Furthermore, the step of adjusting the fresh air deflector in the fresh air mode according to the outdoor temperature and / or the indoor air quality includes:

[0039] When the target operating mode is cooling mode or dehumidification mode, if the outdoor temperature is greater than the preset second high temperature threshold and the fresh air mode is manually turned on by the user, the fresh air fan speed is adjusted according to the preset low fan speed mode.

[0040] When the target operating mode is heating mode, if the outdoor temperature is less than the preset low temperature threshold and the fresh air mode is manually turned on by the user, the fresh air damper is adjusted according to the preset low damper mode.

[0041] When the target operating mode is ventilation mode, adjust the fresh air deflector in fresh air mode according to the indoor air quality;

[0042] When the target operating mode is cooling mode, dehumidification mode or heating mode, if the outdoor temperature is less than or equal to a preset second high temperature threshold, or if the outdoor temperature is greater than or equal to a preset low temperature threshold, the fresh air deflector in the fresh air mode is adjusted according to the indoor air quality.

At the same time, it determines the indoor air quality based on indoor air data, and then selects and activates the fresh air mode under the target operating mode based on the outdoor temperature and / or indoor air quality. Based on the outdoor temperature and / or indoor air quality, it adjusts the fresh air deflector under the fresh air mode. This realizes the automatic adjustment of the air conditioner's cooling, heating, dehumidification, humidification, and ventilation based on indoor and outdoor temperature, indoor relative humidity, and indoor air quality, and automatically selects the appropriate fresh air mode and adjusts the corresponding fresh air deflector.

Detailed Implementation

[0070] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Generally, the components of the embodiments of the present invention described and shown in the accompanying drawings can be arranged and designed in various different configurations.

[0071] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0072] It should be noted that relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0073] The all-weather regulation and control method provided in this invention can be applied to, for example... Figure 1 The all-weather control system 1000 shown includes an air conditioner 100, a temperature sensor 200, a humidity sensor 300, a TVOC sensor 400, a pressure sensor 500, and a CO2 sensor 600.

[0074] Multiple temperature sensors 200 can be installed, one outdoors and one indoor unit with air conditioning, to obtain indoor and outdoor temperatures.

[0075] Both the TVOC sensor 400 and the CO2 sensor 600 are installed indoors where the air conditioner 100 is installed to acquire indoor air data. The indoor air data includes TVOC concentration and CO2 concentration.

[0076] Multiple humidity sensors 300 can be installed, one outdoors and one indoor unit with air conditioning, to obtain indoor and outdoor relative humidity.

[0077] The pressure sensor 500 can be installed indoors or outdoors to obtain the local atmospheric pressure where the air conditioner 100 is installed.

[0078] The structure of air conditioner 100 can be as follows Figure 2 As shown, the air conditioner 100 is an inverter air conditioner 100, which includes an indoor unit 10 and an outdoor unit 20. The indoor unit 10 and the outdoor unit 20 are connected by pipes to transfer refrigerant. The indoor unit 10 includes an indoor heat exchanger 101 and an indoor fan 102. The outdoor unit 20 includes a compressor 201, a four-way valve 202, an outdoor heat exchanger 203, an outdoor fan 204, and an expansion valve 205. The compressor 201, the outdoor heat exchanger 203, the expansion valve 205, and the indoor heat exchanger 101, connected in sequence, form a refrigerant circuit. The refrigerant circulates in the refrigerant circuit and exchanges heat with the air through the outdoor heat exchanger 203 and the indoor heat exchanger 101, respectively, to achieve the cooling mode or heating mode of the air conditioner 100.

[0079] Compressor 201 is used to compress refrigerant so that low-pressure refrigerant is compressed to form high-pressure refrigerant.

[0080] The outdoor heat exchanger 203 is used to exchange heat between outdoor air and the refrigerant transported within it. For example, in the cooling mode of the air conditioner 100, the outdoor heat exchanger 203 operates as a condenser, causing the refrigerant compressed by the compressor 201 to dissipate heat to the outdoor air and condense. In the heating mode of the air conditioner 100, the outdoor heat exchanger 203 operates as an evaporator, causing the depressurized refrigerant to absorb heat from the outdoor air and evaporate.

[0081] The outdoor fan 204 draws outdoor air into the outdoor unit 20 through the outdoor air inlet and discharges the outdoor air after heat exchange with the outdoor heat exchanger 203 through the outdoor air outlet. The outdoor fan 204 provides power for the flow of outdoor air.

[0082] Expansion valve 205 is connected between outdoor heat exchanger 203 and indoor heat exchanger 101. The opening degree of expansion valve 205 regulates the refrigerant pressure flowing through both heat exchangers, thereby regulating the refrigerant flow rate between them. The flow rate and pressure of the refrigerant flowing between these two heat exchangers affect their heat exchange performance. Expansion valve 205 can be an electronic valve. The opening degree of expansion valve 205 is adjustable to control the flow rate and pressure of the refrigerant flowing through it.

[0083] The four-way valve 202 is connected to the refrigerant circuit. The four-way valve 202 is used to switch the flow direction of the refrigerant in the refrigerant circuit so that the air conditioner 100 can perform the cooling mode or the heating mode.

[0084] The indoor heat exchanger 101 is used to exchange heat between indoor air and the refrigerant transported within it. For example, in the cooling mode of the air conditioner 100, the indoor heat exchanger 101 operates as an evaporator, causing the refrigerant, after dissipating heat via the outdoor heat exchanger 203, to absorb heat from the indoor air and evaporate. In the heating mode of the air conditioner 100, the indoor heat exchanger 101 operates as a condenser, causing the refrigerant, after absorbing heat via the outdoor heat exchanger 203, to dissipate heat to the indoor air and condense.

[0085] The indoor fan 102 is used to draw indoor air into the indoor air conditioning unit 10 through the indoor air inlet, and to send the indoor air, after heat exchange with the indoor heat exchanger 101, out through the indoor air outlet of the indoor air conditioning unit 10. The indoor fan 102 provides power for the flow of indoor air.

[0086] The air conditioner 100 also includes a controller 30. The controller 30 is used to control the operation of the compressor 201, and also to control the opening degree of the expansion valve 205, the speed of the outdoor fan 204, and the speed of the indoor fan 102. The controller 30 is connected to the compressor 201, the expansion valve 205, the outdoor fan 204, and the indoor fan 102 via a data cable to transmit communication information.

[0087] In one possible implementation, an all-weather regulation and control method is provided, referring to... Figure 3 This may include the following steps, in this embodiment, applying the all-weather control method to... Figure 2 Let's take controller 30 as an example.

[0088] When the user selects the AI ​​fresh air mode, or when the air conditioner automatically enters the AI ​​fresh air mode after being turned on, the following steps are performed within each adjustment cycle. The duration of the adjustment cycle can be flexibly set according to needs; this implementation does not impose a specific limitation.

[0089] S11: Obtain outdoor temperature, indoor temperature, and indoor relative humidity, and select and start the target operating mode from various operating modes based on the outdoor temperature, indoor temperature, and indoor relative humidity.

[0090] In this embodiment, the operating mode may include cooling mode, heating mode, dehumidification mode, humidification mode, and ventilation mode.

[0091] S13, acquire indoor air data, and determine indoor air quality based on the indoor air data.

[0092] Steps S13 and S11 can be executed simultaneously.

[0093] S15, select and activate the fresh air mode under the target operating mode based on the outdoor temperature and / or indoor air quality.

[0094] In this embodiment, the fresh air mode includes, but is not limited to, air supply mode, exhaust mode, and powerful mode. Among them, the powerful mode is a mode of fresh air supply plus auxiliary exhaust.

[0095] S17, adjusts the fresh air deflector in fresh air mode according to outdoor temperature and / or indoor air quality.

[0096] AI fresh air mode is an all-weather intelligent temperature control, dehumidification and oxygen purification mode. After entering AI fresh air mode, the air conditioner 100 will automatically operate according to the above steps S11 to S15 in each adjustment cycle.

[0097] When the air conditioner 100 is first turned on and enters AI fresh air mode, it operates in ventilation mode for a preset forced start time (e.g., 30 seconds), with the fresh air fan speed set to low. After the forced start time, within each adjustment cycle, it acquires the current outdoor temperature, indoor temperature, and indoor relative humidity, and selects either cooling, heating, dehumidification, humidification, or ventilation mode as the target operating mode based on these parameters.

[0098] Simultaneously, the indoor air quality is determined based on current indoor air data. After determining the indoor air quality and target operating mode, the fresh air mode under the target operating mode is selected and activated based on the outdoor temperature and / or indoor air quality, i.e., supply air mode, exhaust air mode, or strong air mode. The fresh air fan speed is then adjusted according to the outdoor temperature and / or indoor air quality.

[0099] It should be noted that in cooling mode, heating mode, dehumidification mode, humidification mode, or ventilation mode, the fresh air mode can be set to default off, air supply mode, exhaust mode, or strong mode.

[0100] The aforementioned all-weather adjustment and control method enables the air conditioner 100 to automatically adjust its cooling, heating, dehumidification, humidification, and ventilation functions based on indoor and outdoor temperatures, indoor relative humidity, and indoor air quality. It also automatically selects the appropriate fresh air mode and adjusts the corresponding fresh air deflector, thereby improving air purification and maintaining the indoor human body within the PMV comfort range, greatly enhancing the user experience.

[0101] The Predicted Mean Vote (PMV) is a comprehensive evaluation index that takes into account many factors related to human thermal comfort, based on the fundamental equation of human thermal balance and the level of subjective thermal sensation in psychophysiology. To maintain indoor human comfort within the PMV comfort range and ensure room thermal comfort in AI fresh air mode, heating and cooling thresholds are set based on thermal environment ergonomic standards.

[0102] Table 1 is a human ergonomic PMV calculation table. As can be seen from Table 1, the human comfort range fluctuates between 23℃ and 26℃ under different relative humidity. Therefore, in one possible implementation, the heating threshold can be 23℃ and the cooling threshold can be 26℃.

[0103] Table 1

[0104]

[0105]

[0106] Furthermore, considering that high outdoor temperatures significantly impact indoor temperatures, a first high-temperature threshold is introduced. The first high-temperature threshold can be flexibly set; for example, it could be 35°C or 36°C. In this embodiment, no specific limitation is made.

[0107] To ensure the selected target operating mode is compatible with indoor temperature, outdoor temperature, and indoor relative humidity, and to maintain the indoor temperature within the human thermal comfort range, heating threshold, cooling threshold, first high temperature threshold, upper humidity threshold, and lower humidity threshold are introduced when selecting the target operating mode in step S11. (Refer to...) Figure 4 The above step S11 can be further implemented as the following steps.

[0108] S110, determine whether the outdoor temperature is greater than the first high temperature threshold. If yes, proceed to step S111; otherwise, proceed to step S112.

[0109] S111 sets the cooling mode as the target operating mode.

[0110] S112, determine whether the air conditioner is entering AI fresh air mode for the first time. If yes, proceed to step S113; otherwise, proceed to step S114.

[0111] S113, take ventilation mode as the target operating mode.

[0112] S114. Determine whether the indoor temperature is within the preset comfortable temperature range. If yes, proceed to step S115; otherwise, proceed to step S120.

[0113] In this embodiment, the comfortable temperature range is the range formed by the heating threshold and the cooling threshold. For example, when the heating threshold is 23°C and the cooling threshold is 26°C, the comfortable temperature range is 23°C to 26°C.

[0114] S115, determine whether the indoor temperature is within the first range and whether the indoor relative humidity is less than the lower humidity threshold. If yes, proceed to step S116; otherwise, proceed to step S117.

[0115] S116, set the humidification mode as the target operating mode.

[0116] S117. Determine whether the indoor temperature is within the second range and whether the indoor relative humidity is greater than the upper limit threshold. If yes, proceed to step S118; otherwise, proceed to step S119.

[0117] In this embodiment, both the first interval and the second region are located within the comfortable temperature range, and the upper limit of the first interval is less than the lower limit of the second interval.

[0118] S118 sets the dehumidification mode as the target operating mode.

[0119] S119, operate in the original operating mode.

[0120] S120: When the indoor temperature is higher than the preset cooling threshold, the cooling mode will be used as the target operating mode; when the indoor temperature is lower than the preset heating threshold, the heating mode will be used as the target operating mode.

[0121] The settings for the lower and upper humidity thresholds can be flexibly selected. For example, the upper humidity threshold can be RHn > 60%, the lower humidity threshold can be RHn < 50%, the upper humidity threshold can also be RHn > 70%, and the lower humidity threshold can also be RHn < 40%. In this embodiment, no specific limitation is made.

[0122] Taking a first high temperature threshold of 35℃, a heating threshold of 23℃, a cooling threshold of 26℃, a first interval of (23, 24], and a second interval of (25, 26] as an example, the outdoor temperature is represented by Tw, and the indoor temperature is represented by Tn. When Tw > 35℃, it operates in cooling mode.

[0123] When Tw ≤ 35℃, select the target operating mode according to Tn as follows:

[0124] (1) If Tn > 26℃, then operate in cooling mode.

[0125] (2) If Tn < 23℃, operate in heating mode.

[0126] (3) If 23≤Tn≤26℃, then when 25<Tn≤26℃ and indoor relative humidity RHn>60%, the system will operate in ventilation mode with auxiliary dehumidification mode. When 23<Tn≤24℃ and indoor relative humidity RHn<50%, the system will operate in ventilation mode with auxiliary humidification mode. If neither of the above two situations applies, the system will operate in the original air conditioning mode.

[0127] When the air conditioner is running in its original operating mode, it will continue to operate in cooling mode if it was originally in cooling mode, and in heating mode if it was originally in heating mode.

[0128] Furthermore, when the air conditioner 100 first enters the AI ​​fresh air mode, it always operates in ventilation mode. In ventilation mode, it can immediately switch to cooling or heating mode according to changes in Tw and Tn. However, after selecting cooling or heating mode, considering the reliable operation of compressor 201 oil return, system pressure balance, and the prevention of cold air blowing during heating, the compressor 201 must be off for more than 10 minutes before it can switch to other modes according to temperature changes in Tw and Tn. After turning off and on again, the operating mode must be selected again.

[0129] Through the above steps S110 to S118, an appropriate operating mode is selected based on the current indoor temperature, outdoor temperature, and indoor relative humidity to maintain the indoor environment within the human PMV comfort range.

[0130] For step S13, the indoor air data includes, but is not limited to, TVOC concentration and CO2 concentration. The method for determining indoor air quality based on indoor air data can be flexibly set. For example, it can be determined by using a pre-trained machine learning model, or it can be processed by preset rules. In this embodiment, no specific limitation is made.

[0131] In one possible implementation, refer to Figure 5 Step S13 can be further implemented as follows.

[0132] S131, determine the first mass based on the TVOC concentration, and determine the second mass based on the CO2 concentration.

[0133] S132, Determine the indoor air quality based on the first mass and the second mass.

[0134] For step S131, multiple concentration thresholds for TVOC and CO2 concentrations can be preset, and a first mass is determined based on the comparison between TVOC concentration and the TVOC concentration threshold. A second mass is determined based on the comparison between CO2 concentration and the CO2 concentration threshold.

[0135] The TVOC concentration threshold can include a first TVOC threshold and a second TVOC threshold, where the first TVOC threshold is greater than the second TVOC threshold. Different first and second TVOC thresholds can be set based on the rising and falling trends of TVOC concentration to establish different hysteresis intervals. The first mass can then be determined based on the comparison between the detected TVOC concentration and the hysteresis interval.

[0136] For example, the first TVOC threshold when the TVOC concentration is decreasing can be 0.6 mg / m3, and the second TVOC threshold can be 0.3 mg / m3. In this case, when a decrease in TVOC concentration is detected or TVOC concentration is detected for the first time, if the TVOC concentration > 0.6 mg / m3, the first quality can be "poor"; if 0.3 mg / m3 ≤ TVOC concentration ≤ 0.6 mg / m3, the first quality can be "good"; and if the TVOC concentration < 0.3 mg / m3, the first quality can be "excellent".

[0137] When TVOC concentration shows an upward trend, the first TVOC threshold can be 0.85 mg / m3, and the second TVOC threshold can be 0.8 mg / m3. Therefore, when an increase in TVOC concentration is detected, if the TVOC concentration > 0.85 mg / m3, the first quality can be "poor"; if 0.8 mg / m3 ≤ TVOC concentration ≤ 0.85 mg / m3, the first quality can be "good"; and if the TVOC concentration < 0.8 mg / m3, the first quality can be "excellent".

[0138] Similarly, the CO2 concentration threshold can also include a first CO2 threshold and a second CO2 threshold, where the first CO2 threshold is greater than the second CO2 threshold. Different first and second CO2 thresholds can be set based on the rising and falling trends of CO2 concentration to establish different hysteresis intervals. The second mass can then be determined based on the comparison between the detected CO2 concentration and the hysteresis interval.

[0139] For example, the first CO2 threshold when the CO2 concentration is decreasing can be 1000 ppm, and the second CO2 threshold can be 700 ppm. In this case, when a decreasing CO2 concentration is detected or in the case of the first detection, if the CO2 concentration > 1000 ppm, the second quality can be "poor"; if 700 ppm ≤ CO2 concentration ≤ 1000 ppm, the second quality can be "good"; and if the CO2 concentration < 700 ppm, the second quality can be "excellent".

[0140] When CO2 concentration shows an upward trend, the first CO2 threshold can be 1200 ppm, and the second CO2 threshold can be 800 ppm. Therefore, when an upward trend in CO2 concentration is detected, if the CO2 concentration > 1200 ppm, the second quality can be "poor"; if 800 ppm ≤ CO2 concentration ≤ 1200 ppm, the second quality can be "good"; and if the CO2 concentration < 80 ppm, the second quality can be "excellent".

[0141] For step S132, the method for determining the indoor air quality based on the first mass and the second mass can be flexibly set. For example, it can be processed according to preset rules, or it can be processed directly using a machine learning model. In this embodiment, no specific limitation is made.

[0142] In one possible implementation, indoor air quality can be determined as follows: when both the first and second quality are "excellent," the indoor air quality is determined to be at level one, and the quality testing equipment can display a "green light"; when either the first or second quality is "good," the indoor air quality is determined to be at level two, and the quality testing equipment can display a "blue light"; when either the first or second quality is "poor," the indoor air quality is determined to be at level three, and the quality testing equipment can display a "yellow light"; when both the first and second quality are "poor," the indoor air quality is determined to be at level four, and the quality testing equipment can display a "red light."

[0143] Considering that when the air conditioner 100 first enters the AI ​​fresh air mode, the indoor air may not be mixed evenly, and the TVOC sensor 400 is still in adaptive learning, the accuracy of the detected TVOC concentration and CO2 concentration is low.

[0144] Therefore, to improve the detection accuracy of TVOC and OC2 concentrations and thus enhance the precision of air quality assessment, in one possible implementation, after the air conditioner 100 enters AI fresh air mode, the indoor fan 102 can be activated and run for a target duration (N minutes). During this period, the indoor air quality is set to level two by default, allowing the TVOC sensor 400 to learn adaptively. After N minutes, the TVOC sensor 400 and CO2 sensor 600 are activated to detect the indoor TVOC and CO2 concentrations periodically (perhaps 2 seconds per cycle), and the indoor air quality is determined according to steps S131 to S132 described above.

[0145] After determining the indoor air quality, the method of selecting the fresh air mode under the target operating mode in step S15 can also be flexibly set, and in this embodiment, it is not limited to a single one.

[0146] In one possible implementation, refer to Figure 6 Step S15 can be further implemented as follows.

[0147] S151: When the outdoor temperature is greater than the preset second high temperature threshold or less than the preset low temperature threshold, the fresh air mode is off by default.

[0148] In this embodiment, the second high-temperature threshold is greater than the first high-temperature threshold. For example, when the first high-temperature threshold is 35°C, the second high-temperature threshold can be 40°C. The low-temperature threshold can be flexibly set according to actual conditions; for example, the low-temperature threshold can be -10°C.

[0149] S152 determines the fresh air mode based on indoor air quality when the outdoor temperature is between the low temperature threshold and the second high temperature threshold.

[0150] For step S152, it can be implemented as follows: when the indoor air quality is at level 1, the fresh air mode is set to default off; when the indoor air quality is at level 2, the fresh air mode is set to exhaust mode; when the indoor air quality is at level 3, the fresh air mode is set to supply mode; when the indoor air quality is at level 4, the fresh air mode is set to strong mode.

[0151] The powerful mode can be used for both fresh air supply and auxiliary exhaust. After running in powerful mode for a duration of M (e.g., 60 minutes), it can switch to the pre-powerful mode, which will switch to fresh air supply, exhaust, or shut off depending on the indoor air quality. This way, once the indoor air quality improves, there's no need to continue running powerful mode, reducing energy consumption. It should be noted that when switching from powerful mode to fresh air supply or exhaust, at least 10 minutes of operation in powerful mode is required. If switching from powerful mode to fresh air off, the 10-minute waiting period is not required; it can be turned off directly.

[0152] Furthermore, when the operating mode is ventilation, there is no time limit for executing the strong fresh air mode.

[0153] Using the above method, when the indoor air quality is at level one, i.e., "excellent", the fresh air mode is turned off by default, and there is no need to turn on the fresh air mode to purify the indoor air. When the indoor air quality is at other levels, i.e., the air quality is poor, the fresh air mode is turned on through exhaust, supply, or strong mode to exchange indoor and outdoor air and purify the indoor air.

[0154] In one possible implementation, step S17 can be further implemented as follows:

[0155] 17-1. When the target operating mode is cooling mode or dehumidification mode, if the outdoor temperature is greater than the preset second high temperature threshold and the fresh air mode is manually turned on by the user, the fresh air fan speed will be adjusted according to the preset low fan speed mode.

[0156] 17-2. When the target operating mode is heating mode, if the outdoor temperature is lower than the preset low temperature threshold and the fresh air mode is manually turned on by the user, the fresh air damper will be adjusted according to the preset low damper mode.

[0157] 17-3 When the target operating mode is ventilation mode, adjust the fresh air deflector in fresh air mode according to the indoor air quality.

[0158] 17-4. When the target operating mode is cooling mode, dehumidification mode or heating mode, if the outdoor temperature is less than or equal to the preset second high temperature threshold, or the outdoor temperature is greater than or equal to the preset low temperature threshold, adjust the fresh air deflector in the fresh air mode according to the indoor air quality.

[0159] Furthermore, based on indoor air quality, adjusting the fresh air deflector in the fresh air mode can be implemented as follows: when the indoor air quality is at level one, adjust the fresh air deflector to the off state; when the indoor air quality is at level two, adjust the fresh air deflector according to the preset low deflector mode; when the indoor air quality is at level three, adjust the fresh air deflector according to the preset medium deflector mode; when the indoor air quality is at level four, adjust the fresh air deflector according to the preset high deflector mode, and after running in high deflector mode for a first duration, adjust the fresh air deflector according to medium deflector mode.

[0160] The duration can be set based on whether the fourth level is the first determination or whether it is the fourth level twice or more consecutively.

[0161] When the fourth level is the first determination, that is, when the air quality is first detected to be at the fourth level, the first duration can be T if one of the following conditions is met. A min, otherwise, the first duration can be T. A-5min, and at T A After 5 minutes, it will switch to low fan speed mode:

[0162] a. The continuous duration of indoor air quality at level 4 is T≥10min;

[0163] b. The continuous duration of indoor air quality at level 4 is T≥5min, and the cumulative time at level 4 is T1≥20min.

[0164] When the fourth level is not the first determination, that is, when the indoor air quality is at the fourth level twice or more consecutively, the first duration of operation in high fan speed mode can be T. M min, and adjust T as follows M Duration:

[0165] a. The continuous duration of indoor air quality at level 4, T > 30 min, T M Extend by 10 minutes;

[0166] b. If the continuous duration of indoor air quality at level 4 is greater than 20 minutes and less than or equal to 30 minutes, then T M Extend by 5 minutes;

[0167] c. The duration of indoor air quality at level 4 is greater than 10 minutes and less than or equal to 20 minutes. M Keep unchanged;

[0168] d. The continuous duration of indoor air quality at level 4 is T≤10min, T M Shorten by 5 minutes.

[0169] In this embodiment, 20≤T M ≤60.

[0170] By linking indoor and outdoor temperature and humidity with indoor air quality, adjusting the fresh air purification operation mode and windshield control, and adjusting the fresh air windshield to a wind speed that matches the indoor air quality, the best fresh air purification control can be achieved and energy consumption reduced.

[0171] Turning on the fresh air system can affect the indoor temperature and humidity balance, thus impacting indoor thermal comfort. To mitigate the impact of fresh air system activation on indoor thermal comfort, the all-weather adjustment and control method provided in this invention incorporates dynamic compensation for the fresh air intake. Specifically, refer to... Figure 7 It may also include the following steps.

[0172] S21 acquires indoor environmental parameters, outdoor environmental parameters, and air conditioning load parameters when the operating mode is cooling mode, heating mode, or dehumidification mode.

[0173] S22: Calculate the compressor frequency adjustment value based on indoor environmental parameters, outdoor environmental parameters, and air conditioning load parameters, and adjust the compressor's operating frequency according to the compressor frequency adjustment value.

[0174] Indoor environmental parameters include, but are not limited to: indoor temperature, water vapor content, fresh air volume corresponding to the fresh air deflector, and indoor air humidity. Outdoor environmental parameters include, but are not limited to: atmospheric pressure, outdoor temperature, and outdoor relative humidity. Air conditioning load parameters include, but are not limited to: indoor air supply volume and compressor operating frequency.

[0175] Reference Figure 8 Step S22 can be further implemented as follows.

[0176] S221 calculates the fresh air volume, indoor air enthalpy, outdoor air enthalpy, and indoor air specific volume based on indoor and outdoor environmental parameters.

[0177] S222 calculates the dynamic fresh air load value based on the fresh air volume, indoor air enthalpy, outdoor air enthalpy, and indoor air specific volume, combined with indoor air humidity.

[0178] S223, calculate the air conditioning load value based on the air conditioning load parameters.

[0179] S224, calculate the ratio of dynamic fresh air load value to air conditioning load value to obtain compressor frequency adjustment value.

[0180] For step S221, the fresh air volume corresponding to the windshield can be determined based on the windshield in the fresh air mode. The calculation methods for the indoor air enthalpy, outdoor air enthalpy, and indoor air specific volume are existing calculation methods and will not be repeated here.

[0181] For step S222, the dynamic fresh air load value is calculated using the fresh air load formula, which includes: Q 新 =(h0-h R ) / n (1+W n Where q represents the fresh air volume, h0 represents the indoor air enthalpy, and h R V represents the enthalpy of outdoor air. n W represents the specific volume of indoor air. n It represents indoor air humidity.

[0182] For step S223, the air conditioning load calculation formula can be used. The air conditioning load calculation formula includes: Q1=F+Bq-CT w +. Where Q1 represents the air conditioner's 1Hz output load, q represents the compressor's 201 operating frequency, q represents the indoor air volume (i.e., fresh air volume), and T wThe outdoor air temperature is represented by A, B, C, and D, which are correction coefficients for compressor 201 frequency, indoor air volume, outdoor load, and air conditioning output load, respectively.

[0183] The frequency adjustment value of compressor 201 can be expressed as: F 调 = 新 / 1, In practical applications, the actual operating frequency of compressor 201 can be subtracted, added to, or multiplied by F. 调 The operating frequency of compressor 201 is obtained, and in this embodiment, no specific limitation is made.

[0184] The all-weather control method provided in this invention, when the air conditioner 100 is automatically running in AI fresh air mode, monitors in real time information such as indoor and outdoor relative humidity, indoor air data, indoor environmental data, and indoor and outdoor temperature. Based on indoor and outdoor temperature, humidity, and indoor air quality, it controls the air conditioner 100 to operate in a target mode, fresh air mode, and fresh air fan speed setting that keeps the indoor PMV (particulate air volume) within the human comfort zone. This achieves all-weather intelligent temperature control, dehumidification, and oxygen purification. Simultaneously, it adjusts the fresh air fan speed setting based on indoor air quality to continuously adjust the fresh air volume and ensure indoor air quality. Furthermore, it can adjust the operating frequency of the compressor 201 based on real-time dynamic fresh air load and air conditioning load values ​​to reduce the impact of fresh air activation on indoor heat and humidity balance, thereby further improving the precise control of temperature and humidity and maintaining the indoor PMV within the human comfort zone as much as possible.

[0185] Based on the same inventive concept as the aforementioned all-weather control method, in one possible embodiment, an all-weather control device 40 is also provided, which can be applied to... Figure 1 Controller 30 in the middle. (Refer to...) Figure 9 The all-weather adjustment and control device 40 may include a control selection module 401, an air monitoring module 402, a fresh air selection module 403, and a windshield adjustment module 404.

[0186] The control selection module 401 is used to acquire the outdoor temperature, indoor temperature, and indoor relative humidity when the air conditioner 100 enters the AI ​​fresh air mode, and select and activate the target operating mode from various operating modes based on the outdoor temperature, indoor temperature, and indoor relative humidity. The operating modes include cooling mode, heating mode, dehumidification mode, humidification mode, and ventilation mode.

[0187] Air monitoring module 402 is used to acquire indoor air data and determine indoor air quality based on the indoor air data.

[0188] The fresh air selection module 403 is used to select and activate a fresh air mode under a target operating mode based on outdoor temperature and / or indoor air quality. The fresh air modes include supply air mode, exhaust air mode, and powerful air mode.

[0189] The windshield adjustment module 404 is used to adjust the fresh air windshield in the fresh air mode according to the outdoor temperature and / or indoor air quality.

[0190] In the aforementioned all-weather adjustment and control device 40, through the coordinated action of the control selection module 401, air monitoring module 402, fresh air selection module 403, and windshield adjustment module 404, the air conditioner 100 is automatically adjusted for cooling, heating, dehumidification, humidification, and ventilation based on indoor and outdoor temperature, indoor relative humidity, and indoor air quality. It also automatically selects a suitable fresh air mode and adjusts the corresponding fresh air windshield, thereby improving the air purification effect and maintaining the indoor human body within the PMV comfort range, greatly enhancing the user experience.
