Description

Technical Field

[0001] The present application relates to the field of intelligent air-conditioning technology, for example, to methods, devices, equipment and storage media for air-conditioning control. Background Art

[0002] When studying the user's thermal comfort environment, it was found that there are a huge number of parameters that affect human comfort, including but not limited to human metabolic rate, clothing thermal resistance, external mechanical work, etc. In order to accurately control the air conditioner to meet human thermal comfort requirements, it is necessary to perform human comfort intelligent control mode PMV control based on the above and more parameters.

[0003] The PMV function of air conditioning mainly includes six influencing factors, among which environmental factors include: indoor ambient temperature, relative humidity, air flow rate, and average radiant temperature; while non-environmental factors include: thermal resistance of human clothing and metabolic rate.

[0004] At present, the detection of thermal resistance of human clothing includes: using intelligent indoor environment detection equipment to collect environmental factor parameters such as air temperature, black ball temperature, relative humidity and wind speed in real time online, using infrared thermal imagers to shoot the temperature field distribution of the whole body of the dressed human body in the room, and calculating the actual thermal resistance of clothing; or obtaining the air temperature value near the human body, and determining the thermal resistance value of the human clothing based on the air temperature value near the human body. However, these acquisition methods are relatively difficult and the accuracy needs to be improved.

[0005] In addition, different groups of people have different metabolic rates. Therefore, in the PMV control process, the group information corresponding to the user needs to be determined. Currently, the collection of group information can be done through voiceprint recognition technology or through manual input by the user. However, these methods have high requirements on the equipment and must be equipped with voice equipment. If the user manually inputs, it is time-consuming and labor-intensive, and it is inconvenient for the elderly and children to operate.

[0006] It can be seen that in the process of air conditioning PMV control, it is difficult to obtain the influencing factors, and the accuracy needs to be improved.

[0007] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field. Summary of the invention

[0008] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. The summary is not an extensive review, nor is it intended to identify key / critical components or delineate the scope of protection of these embodiments, but rather serves as a prelude to the detailed description that follows.

It can be seen that the factors affecting the PMV control of the air conditioner can be obtained directly through the NFC tag, thereby making the air conditioner PMV control process easier to implement, thereby increasing the wide application of air conditioner PMV.

[0032] In order to be able to understand the features and technical contents of the embodiments of the present disclosure in more detail, the implementation of the embodiments of the present disclosure is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present disclosure. In the following technical description, for the convenience of explanation, a full understanding of the disclosed embodiments is provided through multiple details. However, one or more embodiments can still be implemented without these details. In other cases, to simplify the drawings, well-known structures and devices can be simplified for display.

[0033] The terms "first", "second", etc. in the specification and claims of the embodiments of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchanged where appropriate, so that the embodiments of the embodiments of the present disclosure described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0034] Unless otherwise stated, the term "plurality" means two or more.

[0035] In the embodiment of the present disclosure, the character " / " indicates that the preceding and following objects are in an "or" relationship. For example, A / B indicates: A or B.

[0036] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0037] In the disclosed embodiment, the user's clothing in the air conditioning area is equipped with a near field communication NFC tag, and the NFC tag includes clothing information, including: ① clothing category information, such as thin long-sleeved shirts, thick long-sleeved shirts, light women's tops, sleeveless short nightgowns, etc.; ② information on the group of people: men, women, etc.; ③ clothing material information: cotton, linen, silk, woolen cloth, leather, chemical fiber, blended, mercerized cotton, chiffon, mulberry silk, etc.; ④ clothing size information; ⑤ washing parameter information, etc. In this way, after the terminal scans the NFC tag on the clothing, it can communicate with the air conditioner or cloud server, and read the NFC tag information after the last scan. In this way, the air conditioner or cloud server can determine the current PMV value according to the current clothing category information and the current clothing group information in the NFC tag information, and then perform the corresponding air conditioner PMV control. It can be seen that in this embodiment, the factors affecting the air conditioner PMV control can be directly obtained through the NFC tag, thereby making the air conditioner PMV control process easier to implement, thereby improving the wide application of air conditioner PMV. In addition, by directly collecting the information carried by the NFC tags on clothing, the information collected through other home appliances and language devices can be more accurate and less costly, further improving the accuracy of air-conditioning PMV control and reducing the cost of air-conditioning control.

[0038] Figure 1 Schematic diagram of a structure of an air conditioning system provided by an embodiment of the present disclosure. Figure 1 As shown, the system includes: an air conditioner 100 and a terminal 200. The terminal 200 has a function of scanning an NFC tag, that is, after the terminal contacts the NFC tag on the clothing worn by the human body, the clothing information included in the corresponding NFC tag can be obtained.

[0039] The air conditioner 100 and the terminal 200 can communicate. In some embodiments, the air conditioner 100 and the terminal 200 can perform short-range wireless communication, which may include: Bluetooth communication, infrared communication, ZigBee communication, or wireless LAN WIFI communication, etc. In this way, the air conditioner 100 can obtain the clothing information reported by the terminal 200, and the clothing information is obtained after the terminal 200 reads the near field communication NFC tag on the clothing worn by the user. In this way, the air conditioner 100 can determine the corresponding comfort PMV value according to the clothing information and operate according to the comfort PMV value.

[0040] In some embodiments, in order to save memory resources on the air conditioner 100 and improve the operating efficiency of the air conditioner 100, Figure 1As shown, the air conditioning system may further include a cloud server 300, which may communicate with the air conditioner 100 and the terminal 200 respectively. Furthermore, after the terminal 200 reads the NFC tag on the clothes worn by the user and obtains the clothes information, it may upload it to the cloud server 300, so that the cloud server 300 may determine the corresponding comfort PMV value according to the clothes information, and control the operation of the air conditioner 100 according to the comfort PMV value.

[0041] It can be seen that in the disclosed embodiment, the air conditioner or the cloud server can determine the corresponding PMV value based on the clothing information of the current user in the air conditioning action area reported by the terminal, and control the operation of the air conditioner according to the PMV value, wherein the clothing information is obtained after the terminal reads the near-field communication NFC tag on the clothes worn by the user.

[0042] Figure 2 FIG. 1 is a flow chart of an air conditioning control method provided by an embodiment of the present disclosure. Figure 2 As shown, the control process of the air conditioner includes:

[0043] Step 201: Upon receiving the human comfort intelligent control mode PMV instruction sent by the air conditioner, obtain the first current parameter information of the current user in the air conditioner action area reported by the terminal, wherein the first current parameter information is obtained after the terminal reads the near field communication NFC tag on the clothes worn by the current user, including: current clothing category information and information on the group of people to whom the current clothes belong.

[0044] At present, the air conditioner can adjust the temperature in the area of ​​action, so it can perform cooling or heating operation according to the received user instructions. Alternatively, the air conditioner can collect the indoor temperature value and outdoor temperature value of the area in real time or regularly, and perform cooling or heating operation according to the collected indoor temperature value and outdoor temperature value. For example: when the current indoor temperature value Ta ≥ 23 ℃, or the current outdoor temperature value Tao ≥ 20 ℃, the air conditioner can perform cooling operation. If the indoor temperature value Ta < 23 ℃, and the current outdoor temperature value Tao < 20 ℃, the air conditioner can perform heating operation.

[0045] No matter the air conditioner is running in cooling or heating mode, PMV mode can be used. PMV is an intelligent control system for human comfort. It can adjust the temperature according to the Chinese people's own optimal comfort and humidity. That is, after turning on PMV mode, the air conditioner will set the optimal target temperature according to the temperature difference between indoor and outdoor.

[0046] In the embodiment of the present disclosure, the air conditioner can start the PMV mode according to the collected indoor temperature value, or the collected indoor temperature value and indoor humidity value. In some embodiments, the air conditioner sends the human body comfort intelligent control mode PMV instruction, including: the air conditioner in the current operation mode obtains the current indoor temperature value in the effective area; when the current indoor temperature value meets the set conditions matching the current operation mode, the air conditioner sends the human body comfort intelligent control mode PMV instruction.

[0047] Among them, during the cooling operation of the air conditioner, if the current indoor humidity value collected is less than the set humidity, and the current indoor temperature value Ta≤target temperature, the air conditioner can be controlled to adopt the anti-direct blowing mode, and the PMV mode can be started at the same time, that is, the air conditioner can send the human body comfort intelligent control mode PMV instruction. For example: the set humidity can be 70%, and the target temperature is 26℃. In this way, if the current indoor humidity value is <70%, the air conditioner can be controlled to enter the maximum air volume cooling mode, and if the current indoor temperature value Ta≤26℃, the air conditioner can be controlled to adopt the anti-direct blowing mode, and the PMV mode can be started at the same time. Of course, if the air conditioner cannot collect the indoor humidity value, then if the current indoor temperature value is ≤26℃, the air conditioner can be controlled to adopt the anti-direct blowing mode, and the PMV mode can be started at the same time.

[0048] During the heating operation of the air conditioner, if the current indoor temperature value collected is greater than or equal to the target temperature, the PMV mode can be activated, that is, the air conditioner can send a PMV instruction for the human comfort intelligent control mode. For example, if the target temperature is 22°C, then the PMV mode can be activated when the current indoor temperature value Ta≥22°C.

[0049] Determine that the air conditioner starts the PMV mode, that is, the air conditioner can send the human comfort intelligent control mode PMV instruction. In this way, when the air conditioner or the cloud server receives the sent human comfort intelligent control mode PMV instruction, it can be determined that the air conditioner has started the PMV mode and needs to automatically set the optimal target temperature.

[0050] In the disclosed embodiment, the comfort PMV value can be determined based on environmental factors and non-environmental factors, and the optimal target temperature corresponding to the air conditioner can be determined based on the comfort PMV value. Among them, the thermal resistance of human clothing and metabolic rate and the like in the non-environmental factors can be determined based on the information included in the near-field communication NFC tag on the clothes worn by the current user in the air-conditioning action area. Therefore, after the terminal contacts the near-field communication NFC tag on the clothes worn by the current user in the air-conditioning action area, it can scan and obtain the corresponding first parameter information, and upload it to the air conditioner or cloud server. In this way, when the human comfort intelligent control mode PMV instruction sent by the air conditioner is received, the air conditioner or cloud server can obtain the first parameter information reported by the terminal, and the current moment corresponds to the first current parameter information.

[0051] The terminal scans the NFC tag to obtain the corresponding clothing information. Therefore, the first parameter information may include: clothing category information and information about the group of people to whom the clothing belongs, and the first current parameter information includes: current clothing category information and information about the group of people to whom the current clothing belongs. The clothing category information includes: underwear, shorts, shirts, sweaters, trousers, etc., and the current group of people to whom the clothing belongs includes: male, female, neutral, etc.

[0052] Step 202: Determine the current clothing thermal resistance value that matches the current clothing category information, and obtain the current comfort PMV value based on the current clothing thermal resistance value and the information of the group to which the current clothing belongs.

[0053] In the disclosed embodiment, the air conditioner can store the corresponding relationship between clothing category information and clothing thermal resistance value, and store the corresponding relationship between crowd information and PMV value calculation formula. Alternatively, the cloud server can store the corresponding relationship between clothing category information and clothing thermal resistance value, and store the corresponding relationship between crowd information and PMV value calculation formula.

[0054] Table 1 is a correspondence between clothing category information and clothing thermal resistance values ​​provided by an embodiment of the present disclosure.

[0055] Clothing category information <![CDATA[Clothing thermal resistance value l cl (m2.k / w)]]> Underwear, shorts, thin socks, sandals 0.05 Skirt, knee-high socks, light top 0.07 Underwear, shirt, trousers 0.095 … …

[0056] Table 1

[0057] In this way, if the air conditioner or cloud server saves the corresponding relationship shown in Table 1, if the current clothing category information in the first current parameter information is underwear, shirt, and trousers, the current clothing thermal resistance value l can be determined. c Of course, the present disclosure is not limited thereto, and the corresponding relationship between clothing category information, clothing belonging to group information and clothing thermal resistance value can also be stored.

[0058] Table 2 is a correspondence between clothing category information, clothing group information and clothing thermal resistance value provided by an embodiment of the present disclosure. In this way, if the air conditioner or cloud server saves the correspondence shown in Table 2, if the current clothing category information in the first current parameter information is underwear, shirt, trousers, shoes, and the current clothing group information is neutral, then the current clothing thermal resistance value l can be determined. c is 0.145.

[0059] The air conditioner or cloud server also stores the relationship between the crowd information and the PMV value calculation formula. In some embodiments, the PMV value calculation formula corresponding to the male crowd information is formula (1), and the PMV value calculation formula corresponding to the female crowd information is formula (2).

[0064] Where M is the human metabolic rate, W is the external mechanical work, P a is the water vapor partial pressure, t a is the indoor temperature, f el is the clothing surface area coefficient, t el is the clothing surface temperature, t r is the average radiation temperature, h c is the convective heat transfer coefficient.

[0065] According to formula (1) and formula (2), the main parameters that affect the PMV value of air conditioning can be determined as follows: M, W, P a ,t a 、f el ,t el ,t r 、h c The human metabolic rate M can also be a set value, such as 70W / M 2 Alternatively, the air conditioner or the cloud server stores the correspondence between the activity state and the human metabolic rate M. Thus, after the air conditioner obtains the current activity state of the current user through the image acquisition device, the corresponding current human metabolic rate M can be determined according to the stored correspondence. Alternatively, after the air conditioner obtains the current activity state of the current user through the image acquisition device, the current activity state is sent to the cloud server, and the cloud server can determine the corresponding current human metabolic rate M according to the stored correspondence.

[0066] Table 3 is a correspondence between an activity state and a human metabolic rate M provided by an embodiment of the present disclosure.

[0067] Activity Status <![CDATA[Human metabolic rate M (w / m 2 )]]> Standing still 70 Lying down 45 Study, work, entertainment (playing games, watching TV) 70 Household chores 115 … …

[0068] Table 3

[0069] If the air conditioner obtains the current activity state of the current user as housework through the image acquisition device and sends it to the cloud server, the cloud server can determine the current human metabolic rate M as 115w / m according to the saved Table 3. 2 .

[0070] The external mechanical work W can be set to a default value, for example, W = 0w / m 2 . And P a ,t a 、f el ,t el ,t r 、h c It is not only related to the current clothing thermal resistance value and the information of the group to which the current clothing belongs, but also related to other parameters obtained by the air conditioner. Therefore, in some embodiments, according to the current clothing thermal resistance value and the information of the group to which the current clothing belongs, obtaining the current comfort PMV value includes: obtaining the second current parameter value reported by the air conditioner, wherein the second current parameter value includes: the current indoor temperature value, the air speed value determined according to the current indoor temperature value, the current indoor humidity value, and the current average radiation temperature value; according to the current clothing thermal resistance value and the second current parameter value, determining the third current parameter value, wherein the third current parameter value includes: the current clothing surface area coefficient f el , Current clothing surface temperature value t el 、Current convective heat transfer coefficient h c, and the current water vapor partial pressure P a ; Determine the current PMV value calculation formula that matches the information of the crowd to which the current clothing belongs; determine the current comfort PMV value through the current PMV value calculation formula based on the second current parameter value and the third current parameter value.

[0071] The air conditioner can obtain the current indoor temperature value t through temperature collection. a , and can be based on the current indoor temperature value t a Determine the air velocity value. In some embodiments, when the air conditioner starts the PMV function, the indoor fan of the air conditioner is at the anti-direct blowing wind speed, then the air velocity value V can be determined to be 0.3m / s, or the maximum V can be determined to be 0.5m / s. The air conditioner can obtain the current indoor humidity value RH through humidity collection, or directly default to the current indoor humidity value RH = 50%. The air conditioner can also read the current average radiation temperature value t through the infrared sensor r Of course, the current average radiation temperature value t can also be used by default r Equal to the current indoor temperature value t a The air conditioner may obtain the second current parameter value. Alternatively, the air conditioner obtains the second current parameter value and reports it to the cloud server.

[0072] After the air conditioner or cloud server obtains the first current parameter value and the second current parameter value, the third current parameter value can be determined, wherein the current clothing surface area coefficient f is determined. el The process includes: cl When ≤0.078, f cl =1.0+1.290I cl ; when I cl When >0.078, f cl =1.05+0.645I cl . Determine the current water vapor partial pressure P a The process includes: And determine the current clothing surface temperature value t el The process includes: cl =35.7-0.028(MW)-Icl·[3.96×10 -8 f cl ×{(t cl +273) 4 -(t r +273) 4}+f cl h c (t cl -t a )]. Determine the current convective heat transfer coefficient h c The process includes:

[0073] After determining the third parameter, a current PMV value calculation formula matching the population information to which the current clothing belongs may be determined, wherein, in some embodiments, determining the current PMV value calculation formula matching the population information to which the current clothing belongs includes: when the population information to which the current clothing belongs is male, determining formula (1) as the current PMV value calculation formula; when the population information to which the current clothing belongs is female, determining formula (2) as the current PMV value calculation formula;

[0074] PMV_Male = (0.303e -0.036M +0.016){(MW)-3.05×10 -3 ×[5733-6.99(MW)-P a ]-0.42×[(MW)-58.15]-1.7×10 -5 M(5867-P a )-0.0014M(34-t a )-3.96×10 -8 f cl ×[(t cl +273) 4 -(t r +273) 4 ]-f cl h c (t cl -t a )}-0.050 (1);

[0075] PMV_female = (0.303e -0.036M +0.033){(MW)-3.05×10 -3 ×[5733-6.99(MW)-P a ]-0.42×[(MW)-58.15]-1.7×10 -5 M(5867-P a )-0.0014M(34-t a )-3.96×10 -8 f cl ×[(t cl +273) 4 -(t r +273) 4 ]-f cl h c (t cl -t a )}-0.227 (2);

[0076] Where M is the human metabolic rate, W is the external mechanical work, P a is the water vapor partial pressure, ta is the indoor temperature value, f el is the clothing surface area coefficient, t el is the clothing surface temperature, t r is the average radiation temperature, h c is the convective heat transfer coefficient.

[0077] Air conditioner or cloud server can be based on M, W, P a ,t a 、f el ,t el ,t r 、h c , and formula (1) or formula (2), determine the current PMV value.

[0078] Step 203: Control the operation of the air conditioner according to the current comfort PMV value.

[0079] In some embodiments, when the current comfort PMV value is greater than the set upper limit of the comfort range, a first control instruction is sent to the air conditioner to lower the target temperature by the set temperature, so that the air conditioner operates according to the first control instruction; when the current comfort PMV value is less than the set lower limit of the comfort range, a second control instruction is sent to the air conditioner to raise the target temperature by the set temperature, so that the air conditioner operates according to the second control instruction.

[0080] For example: set the comfort interval [-0.5, 0.5], so that the upper limit is 0.5 and the lower limit is -0.5. If the current PMV value is > 0.5, the air conditioner will determine the first control instruction with the target temperature -0.5℃ instruction and operate according to the first control instruction. Alternatively, if the current PMV value is > 0.5, the cloud server will determine the first control instruction with the target temperature -0.5℃ instruction and send it to the air conditioner, and the air conditioner will operate according to the first control instruction.

[0081] If the current PMV value is <-0.55, the air conditioner can determine the first control instruction with the target temperature + 0.5℃ instruction and can operate according to the first control instruction. Alternatively, if the current PMV value is >0.5, the cloud server will determine the first control instruction with the target temperature + 0.5℃ instruction and send it to the air conditioner, and the air conditioner will operate according to the first control instruction. That is, the air conditioner realizes the PMV mode operation with automatic setting of the target temperature.

[0082] It can be seen that in this embodiment, the factors affecting the PMV control of the air conditioner can be directly obtained through the NFC tag, and after obtaining the corresponding PMV value, the operation of the air conditioner can be controlled according to the PMV value, thereby making the air conditioner PMV control process easier to implement, thereby improving the extensive application of air conditioner PMV. In addition, by directly collecting the information carried by the NFC tag of clothing, the information collected through other home appliances and language devices can be more accurate and the cost is lower, further improving the accuracy of the air conditioner PMV control and reducing the cost of air conditioner control.

[0083] The operation flow is collected into a specific embodiment below to illustrate the air conditioning control process provided by the embodiment of the present invention.

[0084] In one embodiment of the present disclosure, a system for air conditioning control is as follows: Figure 1 As shown, the cloud server can communicate with the air conditioner and the terminal respectively, and the terminal has the function of scanning the NFC tag.

In addition, the human metabolic rate is configured to be 70w / m 2 , external mechanical function W = 0w / m 2 , air speed value v = 0.3m / s.

[0086] Step 301: The cloud server receives the current clothing information reported by the terminal after reading the near field communication NFC tag on the clothing worn by the current user in the air conditioning effective area.

[0087] Step 302: Does the cloud server receive the PMV instruction sent by the air conditioner? If yes, go to step 303; otherwise, go back to step 301.

[0088] Step 303: The cloud server obtains the first current parameter information of the current user from the current clothing information. The first current parameter information includes: the current clothing category information and the information of the group to which the current clothing belongs.

[0089] Step 304: The cloud server obtains the second current parameter value reported by the air conditioner, wherein the second current parameter value includes: the current indoor temperature value t a , the current indoor humidity value RH, and the current average radiation temperature value t r .

[0091] Step 306: The cloud server determines that formula (1) or formula (2) is the current PMV value calculation formula based on the information of the group to which the current clothing belongs.

[0092] Step 307: The cloud server determines the current comfort PMV value according to the second current parameter value, the third current parameter value and the current PMV value calculation formula.

[0112] The third determination unit is configured to determine the current comfort PMV value according to the second current parameter value and the third current parameter value by using the current PMV value calculation formula.

[0113] In some embodiments, the second determination unit is specifically configured to determine formula (1) as the current PMV value calculation formula when the population information to which the current clothing belongs is male; and to determine formula (2) as the current PMV value calculation formula when the population information to which the current clothing belongs is female.

[0114] PMV_Male = (0.303e -0.036M +0.016){(MW)-3.05×10 -3 ×[5733-6.99(MW)-P a ]-0.42×[(MW)-58.15]-1.7×10 -5 M(5867-P a )-0.0014M(34-t a )-3.96×10 -8 f cl ×[(t cl +273) 4 -(t r +273) 4 ]-f cl h c (t cl -t a )}-0.050 (1);

[0115] PMV_female = (0.303e -0.036M +0.033){(MW)-3.05×10 -3×[5733-6.99(MW)-P a ]-0.42×[(MW)-58.15]-1.7×10 -5 M(5867-P a )-0.0014M(34-t a )-3.96×10 -8 f cl ×[(t cl +273) 4 -(t r +273) 4 ]-f cl h c (t cl -t a )}-0.227 (2);

[0116] Where M is the human metabolic rate, W is the external mechanical work, P a is the water vapor partial pressure, t a is the indoor temperature value, f el is the clothing surface area coefficient, t el is the clothing surface temperature, t r is the average radiation temperature, h c is the convective heat transfer coefficient.

[0117] In some embodiments, the control module 430 includes:

[0118] The first control unit is configured to send a first control instruction to the air conditioner to lower the target temperature by a set temperature when the current comfort PMV value is greater than the set upper limit of the comfort range, so that the air conditioner operates according to the first control instruction.

[0119] The second control unit is configured to send a second control instruction to the air conditioner to increase the target temperature by the set temperature when the current comfort PMV value is less than the set comfort range lower limit value, so that the air conditioner operates according to the second control instruction.

[0120] The air conditioning control process for the air conditioning control device is further described below in conjunction with the embodiments.

[0121] In this embodiment, the system for air conditioning control is as follows: Figure 1 As shown, the cloud server can communicate with the air conditioner and the terminal respectively, and the terminal has the function of scanning the NFC tag. In addition, the human metabolic rate is configured to be 70w / m 2 , external mechanical function W = 0w / m 2 , air speed value v = 0.5m / s.

[0122] Figure 5Schematic diagram of a structure of an air conditioning control device provided by an embodiment of the present disclosure. Figure 5 As shown, the air conditioning control device 400 includes: an acquisition module 410, a determination module 420, a control module 430, and a storage module 440, wherein the determination module 420 includes: an acquisition unit 421, a first determination unit 422, a second determination unit 423 and a third determination unit 424; the control module 430 includes: a first control unit 431 and a second control unit 432.

[0123] In this embodiment, the storage module 440 stores the corresponding relationship shown in Table 2, and stores formula (1) and formula (2). In this way, after receiving the current clothing information reported by the terminal after reading the NFC tag on the clothing worn by the current user in the air conditioner action area, if the PMV instruction sent by the air conditioner is received, the acquisition module 410 can obtain the first current parameter information of the current user from the current clothing information. The first current parameter information includes: current clothing category information and current clothing group information.

[0124] Thus, the acquisition unit 421 in the determination module 420 can acquire the second current parameter value reported by the air conditioner, wherein the second current parameter value includes: the current indoor temperature value t a , the current indoor humidity value RH, and the current average radiation temperature value t r Thus, the first determination unit 422 can determine the current clothing thermal resistance value l corresponding to the current clothing category information and the information of the group to which the current clothing belongs according to Table 2. cl , and according to the current clothing thermal resistance value l cl , current indoor temperature value t a , the current indoor humidity value RH, and the air velocity value v determine the third current parameter value, including: the current clothing surface area coefficient f el , Current clothing surface temperature value t el 、Current convective heat transfer coefficient h c , and the current water vapor partial pressure P a The second determination unit 423 determines that formula (1) or formula (2) is the current PMV value calculation formula according to the information of the group to which the current clothing belongs. Thus, the third determination unit 424 determines the current comfort PMV value according to the second current parameter value and the third current parameter value through the current PMV value calculation formula.

[0125] If the current PMV value is greater than 0.5, the first control unit 431 in the control module 430 determines the first control instruction with the instruction of the target temperature -0.5℃, and sends it to the air conditioner, so that the air conditioner operates according to the first control instruction; when the current PMV value is less than -0.5, the second control unit 432 in the control module 430 determines the first control instruction with the instruction of the target temperature +0.5℃, and sends it to the air conditioner, so that the air conditioner operates according to the first control instruction. Of course, when the current PMV value is between [-0.5,0.5], the control module 430 determines the first control instruction with the instruction of the target temperature unchanged, and sends it to the air conditioner, so that the air conditioner operates according to the first control instruction.

[0126] It can be seen that in this embodiment, the device for air conditioning control can directly obtain the factors affecting the PMV control of the air conditioner through the NFC tag, and after obtaining the corresponding PMV value, the operation of the air conditioner can be controlled according to the PMV value, thereby making the air conditioner PMV control process easier to implement, thereby improving the extensive application of air conditioner PMV. In addition, by directly collecting the information carried by the NFC tag of clothing, the information collected through other home appliances and language devices can be more accurate and the cost is lower, further improving the accuracy of air conditioner PMV control and reducing the cost of air conditioner control.
