Technical Field

The present invention relates to the field of wireless communication technologies, and in particular, to a terminal device and a method for calculating a PMV (Predicted Mean volume) value.

Background

The indoor hot and humid environment refers to a physical environment formed by indoor temperature and relative humidity which are directly sensed by people, and the feeling of people on the indoor hot and humid environment is called as indoor hot and humid environment thermal comfort level, which is called as thermal comfort level for short. The quantitative criterion for thermal comfort is referred to as the thermal comfort index.

At present, the following six factors mainly influence the thermal comfort PMV value: indoor ambient temperature, s indoor relative humidity, indoor air flow rate, average radiation temperature, human clothing thermal resistance and metabolism rate. And inputting the influence factors into a traditional PMV model, outputting a PMV value, and judging whether the current physical environment meets the requirement of thermal comfort of people or not according to the obtained PMV value.

Since the PMV value obtained by the conventional PMV model is a universal PMV value, the accuracy is low, and the evaluation of the thermal comfort level of the user is inaccurate.

The device, the memory stores data or program codes used when the terminal device runs, the processor executes the program codes and executes the following processes: the method comprises the steps of firstly, determining an indoor somatosensory temperature parameter according to an indoor temperature parameter, an indoor relative humidity parameter and an indoor air flow velocity parameter which are collected, then determining an indoor comfortable temperature interval according to an outdoor temperature parameter and current geographical position information, and inputting the indoor somatosensory temperature parameter serving as an indoor temperature parameter into a PMV model to obtain a PMV value if the determined indoor somatosensory temperature parameter is within the determined indoor comfortable temperature interval. Because the indoor temperature parameter of inputing into the PMV model is indoor body and feels temperature parameter, and indoor body feels temperature parameter is in indoor comfort level interval, consequently the PMV value that obtains in inputing PMV model with indoor body and feels temperature parameter as indoor temperature parameter more accords with user's hot comfort level demand to can improve the accuracy of PMV value, it is more accurate to user's hot comfort level evaluation.

Detailed Description

To make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that the embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of terminal devices and methods consistent with certain aspects of the invention, as detailed in the appended claims.

The term "intelligent household appliance" in the embodiment of the invention is a household appliance product formed by introducing a microprocessor, a sensor technology and a network communication technology into household appliances, such as an intelligent air conditioner, an intelligent humidifier, an intelligent air purifier, an intelligent fresh air machine and the like.

The application scenario described in the embodiment of the present invention is for more clearly illustrating the technical solution of the embodiment of the present invention, and does not form a limitation on the technical solution provided in the embodiment of the present invention, and it can be known by a person skilled in the art that with the occurrence of a new application scenario, the technical solution provided in the embodiment of the present invention is also applicable to similar technical problems. Wherein, in the description of the present invention, unless otherwise indicated, "a plurality" means.

At present, a traditional thermal comfort PMV model is mainly adopted for indoor environment evaluation, and a thermal comfort value is calculated according to environmental factors (temperature, relative humidity and air flow rate) and human factors (clothing thermal resistance and human metabolic rate). The thermal comfort PMV model is an evaluation index for representing human thermal reaction (thermal sensation) proposed by professor van guerre (p.o.fanger) in denmark, and represents the average of the thermal sensation of most people in the same environment. Indexes provided by the model represent average voting values of most people to a hot environment, and the indexes have seven levels of feelings, namely cold (-3), cold (-2), slightly cold (-1), moderate (0), slightly warm (1), warm (2) and hot (3). The recommended value of PMV is between-0.5 and + 0.5.

The conventional PMV model is briefly explained below.

The traditional comfort model comprehensively considers two major influence factors, namely environmental factors (air temperature, relative humidity and air flow rate) and human factors (clothing thermal resistance and human body metabolic rate), is a relatively comprehensive index considering a plurality of factors of thermal comfort, and is also a relatively authoritative and representative thermal comfort evaluation index.

The PMV value calculation formula is as follows:

PMV＝(0.303e ^-0.036M +0.028){(M-W)-3.05×10 ^-3 ×[5733-6.99(M-W)-p _a ]-0.42

×[(M-W)-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 _mrt +273) ⁴ ]-f _cl h _c (t _cl -t _a )}

the parameters involved in the formula are:

m: the human body metabolism is 69.8W/m2, which is the average metabolism of a normal human body when the human body sits still or walks, and the human body movement metabolism is increased along with the increase of the movement amount; at the same time, the value can be differentiated according to gender: the average metabolism of men is 80.1W/m2 as default, and 64.3W/m2 of women.

W: mechanical work, which is related to mechanical efficiency, is taken to be 0 by default.

Fcl: the clothing coefficient is the ratio of the outer surface area of the clothing to the surface area of the body wrapped by the clothing. It can be calculated from the garment thermal resistance Ic, fcl ═ 1+0.2Ic, where Ic is related to the garment itself.

The garment thermal resistance value Ic is a parameter reflecting the thermal insulation performance of the garment. Its value is inversely proportional to the garment thermal conductivity in clo. 1clo is 0.155 m.k/W. The measured data of the thermal resistance values of various clothes can be checked. It has close relation with ambient temperature, wind speed and human body heat dissipation.

Ta: ambient air temperature, which can be measured by instrumentation.

Tmrt: radiation temperature, by default equal to air temperature. Tmrt +273.15 ta + 273.15.

Pa: the water vapor pressure can be calculated by saturated water vapor pressure and relative humidity rh (relative humidity), wherein the saturated water vapor pressure at different temperatures can be obtained by looking up a table, and the table is a universal table.

Hc: convective heat transfer coefficient, related to the air flow rate va. When air naturally convects, hc takes a value interval [3,10 ]. The corresponding conversion relation between hc and the air flow rate va is as follows: hc ═ max (2.38 × tcl-ta) ^0.25,12.1 × va ^ 0.5).

Tcl: the surface temperature of the body of the wearer.

As can be seen from the above description of the PMV model, the thermal comfort value index calculated by the conventional PMV model comprehensively considers the influence of the indoor environment variables and the human body variables on the thermal comfort of the human body, but does not consider other factors, such as the geographical location, the season, the outdoor temperature, and the like. The geographical position, season and outdoor temperature of the actual user also have certain influence on the thermal comfort of the human body.

For example, in winter, the outdoor temperature of a city in the north of China is-10 ℃, and when the indoor temperature reaches about 17 ℃, a human body feels more comfortable; in summer, the outdoor temperature of the area is 30 ℃, and when the indoor temperature reaches about 26 ℃, a human body feels comfortable.

For another example, when the indoor temperature is 25 ℃, the sensible temperature of the human body is about 24 ℃.

The embodiment of the invention provides a terminal device for calculating a PMV value, wherein a memory of the terminal device stores data or program codes used when the terminal device runs, and a processor executes the program codes and executes the following processes: the method comprises the steps of firstly, determining an indoor somatosensory temperature parameter according to an indoor temperature parameter, an indoor relative humidity parameter and an indoor air flow rate parameter which are collected, then determining an indoor comfortable temperature interval according to an outdoor temperature parameter and current geographical position information, and inputting the indoor somatosensory temperature parameter serving as an indoor temperature parameter into a PMV model to obtain a PMV value if the determined indoor somatosensory temperature parameter is in the determined indoor comfortable temperature interval. Because the indoor temperature parameter of inputing into the PMV model is indoor body and feels temperature parameter, and indoor body feels temperature parameter is in indoor comfort level interval, consequently regard indoor body to feel temperature parameter as indoor temperature parameter input into the PMV model, the PMV value that obtains more accords with user's thermal comfort level to can improve the accuracy of PMV value, it is more accurate to user's thermal comfort level evaluation.

s501, determining an indoor comfortable temperature interval according to the outdoor temperature parameter and the current geographical position information;

and S502, if the somatosensory temperature parameter is in the indoor comfortable temperature interval, inputting the somatosensory temperature parameter serving as an indoor temperature parameter into a PMV model to obtain a PMV value.

Because the indoor temperature parameter input into the PMV model is an indoor somatosensory temperature parameter, the indoor somatosensory temperature parameter is in an indoor comfortable temperature interval, and the indoor comfortable temperature interval is determined according to outdoor temperature and current geographical position information, the indoor somatosensory temperature parameter is input into the PMV model as the indoor temperature parameter, and the obtained PMV value is more in line with the thermal comfort of a user, so that the accuracy of the PMV value can be improved, and the thermal comfort of the user can be evaluated more accurately.

In implementation, the somatosensory temperature parameter is input into the PMV model as an indoor temperature parameter to obtain a PMV value, and then the intelligent household appliance is controlled according to the obtained PMV value.

Specifically, the PMV value may be calculated in response to a user instruction to adjust the thermal comfort level before calculating the PMV value.

Instead of calculating the PMV value in response to a user instruction to adjust the thermal comfort level, the calculation may be performed periodically, such as once every 2 minutes.

After responding to the instruction of adjusting the thermal comfort degree of the user, the indoor somatosensory temperature parameter can be determined according to the collected indoor temperature parameter, the collected indoor relative humidity parameter and the collected indoor air flow rate parameter.

In the smart home system, indoor environment data, i.e., indoor temperature, indoor relative humidity, and indoor air flow rate, may be collected using indoor air-related devices (air conditioner, fresh air machine) or separate air detection devices (four constant controllers).

The collected indoor environment data may be collected by one sensor, or may be an average value of data collected by a plurality of sensors in order to make the obtained indoor environment data more accurate.

For example, the indoor temperature parameter may be acquired by one temperature sensor in the room, or may be an average value of a plurality of temperature parameters acquired by a plurality of temperature sensors located at different positions in the room, that is, an indoor average temperature value.

After the indoor temperature parameter, the indoor relative humidity parameter and the indoor air flow rate parameter are determined, the indoor sensible temperature parameter is determined according to the indoor temperature parameter, the indoor relative humidity parameter and the indoor air flow rate parameter.

Specifically, if the indoor temperature parameter is within a set temperature interval, or the indoor temperature parameter is within a set temperature interval, and the indoor relative humidity parameter is within a set humidity interval, the indoor sensible temperature parameter is determined according to the weighted sum of the indoor temperature parameter, the indoor relative humidity parameter, and the indoor air flow rate parameter.

First, the sensible temperature will be briefly described.

The sensible temperature is a temperature sensation that a human feels cold and warm, and is a concept of representing human body sensation in contrast to an ambient temperature. The body sensing temperature theory is established based on a human body adaptability theory, the influence of 3 adjustable factors of indoor temperature, indoor relative humidity and indoor air flow rate on the body sensing temperature is considered from the actual indoor environment, and the following expression is established:

T _g ＝f(T _a ,T _u ,T _v )

wherein, T _g Is a bodyTemperature, T _a Is the indoor temperature, T _u Is the indoor relative humidity, T _v Is the indoor air flow rate.

In an indoor environment, the indoor temperature is a main influence factor of the sensible temperature, and influences the heat loss speed of a human body so as to influence the heat sensation of the human body;

the indoor air flow rate is generally recommended to be set below 0.2m/s, and the influence on the human body perspiration is small;

the indoor air flow rate has no significant effect on the PMV value, so the effect of the indoor air flow rate on the sensible temperature is negligible, i.e. T _v ＝0。

Indoor relative humidity has certain influence on body sensing temperature, and when the environmental temperature is higher, the perspiration of a human body is influenced by the increase of the humidity, so that the heat sensation of the human body is intensified; under low temperature conditions, high humidity can cause a person to feel cool, thereby exacerbating the cold sensation.

The adjustable range of the humidifying equipment arranged in the room is 30-80%.

According to the analysis, on the basis of the change of the indoor temperature, according to the influence of the indoor temperature and the indoor relative humidity on the sensible temperature, an indoor sensible temperature calculation formula can be constructed:

when the temperature is less than or equal to 27 ℃ and T _a Less than or equal to 32 ℃ or T _a T is more than or equal to 77% and 26 DEG C _u When the content is less than or equal to 80 percent,

T _g ＝k ₁ T _a +k ₂ T _u -3.94

when the temperature is less than or equal to 18 ℃ and T is less than or equal to _a Not more than 25 ℃ or T _a T is more than or equal to 30 percent and 26 DEG C _u When the content is less than or equal to 77 percent,

T _g ＝k ₁ T _a +k ₂ T _u +k ₃ T _a T _u +k ₄ T _a ² +k ₅ T _u ² +k ₆ T _u T _a ² +k ₇ T _a T _u ² +k ₈ T _a ² T _u ² -41.321

wherein, T _g Is the sensible temperature of the room, T _a Is the indoor temperature, T _u Is the indoor relative humidity, k _n Is a temperature influencing factor.

It should be noted here that the temperature influencing factor is obtained by performing a large number of experiments based on measured data.

And obtaining a corresponding relation table of the indoor sensible temperature, the indoor temperature and the indoor relative humidity by a polling mode based on the indoor sensible temperature calculation formula, wherein the corresponding relation table is shown in a table 1.

TABLE 1

The above is an explanation of how to specify the room sensible temperature, and the following is an explanation of how to specify the room comfortable temperature zone.

Firstly, determining the binding relationship of geographical position information, geographical position influence factors and geographical position influence constants, wherein the binding relationship is determined by acquiring a large amount of data and carrying out a large amount of experiments. And then determining a geographic position influence factor and a geographic position influence constant corresponding to the current geographic position information according to the binding relationship.

In order to make the binding relationship among the geographic location information, the geographic location influence factor, and the geographic location influence constant clearer, the binding relationship is presented in the form of a table below.

As shown in table 2, when the geographic position information is south, the geographic position influence factor is 0.82, and the geographic position influence constant is 14.8, and when the geographic position information is north, the geographic position influence factor is 0.42, and the geographic position influence constant is 15.7.

Geographical location information	Geographical location impact factor	Geographic location impact constants
			South	0.82	14.8
North China	0.42	15.7

TABLE 2

It should be noted that the data in the table is only an example of the binding relationship, and specific values of the geographic location influence factor and the geographic location influence constant may be specifically determined in implementation, which is not limited in the embodiment of the present invention.

And after the geographical position influence factor and the geographical position influence constant corresponding to the current geographical position information are determined, converting the outdoor temperature parameter into the indoor comfortable temperature parameter by using the determined geographical position influence factor and the geographical position influence constant.

For example, with T _in Indicating indoor comfort temperature parameter, by T _out Representing the outdoor temperature, the geographical position influence factor by a, and the geographical position influence constant by n, the indoor comfort temperature parameter T may be represented using the following expression _in ：

T _in ＝a*T _out +n

And after the indoor comfortable temperature parameter is determined, determining an indoor temperature comfortable interval according to a preset temperature error.

The temperature error is obtained by acquiring a large amount of temperature data and then performing a large amount of experiments.

For example, the determined indoor comfortable temperature parameter is 23 ℃, the preset temperature error is ± 3 ℃, and the indoor temperature comfortable interval is 20-26 ℃.

The indoor temperature comfort zone may approximate the zone shown in fig. 6 based on a large amount of historical data.

As shown in fig. 6, the light color in the coordinate system indicates an indoor temperature comfort zone that is acceptable to 90% of users, and the dark color indicates an indoor temperature comfort zone that is acceptable to 80% of users.

If the determined somatosensory temperature parameter is not in the determined indoor comfortable temperature interval, the determined somatosensory temperature parameter is not in accordance with the user requirement, so that indoor environment parameters such as an indoor temperature parameter, an indoor relative humidity parameter and an indoor air flow rate parameter need to be adjusted according to the somatosensory temperature parameter.

Specifically, in the adjusting process, if the determined somatosensory temperature parameter is smaller than the minimum value of the indoor comfortable temperature interval, the somatosensory temperature parameter is too small, and the current indoor temperature parameter needs to be properly increased, the indoor relative humidity parameter needs to be decreased, and the indoor air flow rate parameter needs to be adjusted until the indoor somatosensory temperature parameter is in the comfortable temperature interval.

If the determined somatosensory temperature parameter is larger than the maximum value of the indoor comfortable temperature interval, the somatosensory temperature parameter is too large, and the current indoor temperature parameter needs to be properly reduced, the indoor relative humidity parameter needs to be increased, and the indoor air flow rate parameter needs to be increased until the indoor somatosensory temperature parameter is in the comfortable temperature interval.

TABLE 5

And S709, informing the decision-making module to adjust the indoor temperature parameter, the indoor relative humidity parameter and the indoor air flow rate parameter according to the indoor somatosensory temperature parameter, and returning to S700.

The above is an explanation of recalculating the PMV value using the geographical location information and the outdoor temperature parameter, and in addition, the PMV value may be adjusted using the geographical location information and the climate information determined by time, where the adjustment may be to adjust the PMV value obtained by the original PMV model, or to adjust the PMV value again by using the geographical location information and the outdoor temperature parameter.

The following is a description of the adjustment of the PMV value using geographical location information and climate information determined by the event.

Referring to fig. 8, a method for adjusting a PMV value according to an embodiment of the present invention includes:

s800, acquiring current geographical position information and current date information after a preset condition is met;

s801, determining comfort degree adjustment values for representing different regions and different time influences on human comfort degrees according to the current geographical position information and the current date information;

s802, adjusting a PMV value by using the comfort degree adjusting value, wherein the PMV value is obtained by inputting the current parameters influencing the comfort degree of the human body into a PMV model.

Because the comfort degree adjusting value in the embodiment of the invention is determined by the current geographical position information and the current date information, the PMV value is adjusted according to different climates in different regions, the accuracy of the PMV value is further improved, and the evaluation on the thermal comfort degree of the user is more accurate.

The embodiment of the invention is applied to intelligent household appliances, such as an intelligent air conditioner, an intelligent humidifier and an intelligent air purifier. And after the PMV value is adjusted by using the comfort adjustment value, controlling the intelligent household appliance according to the adjusted value.

The preset condition may be a command for adjusting the PMV value in response to a user, or may be that the obtained comfort PMV value exceeds a set range.

For example, in the smart home system, the collector periodically collects the temperature, the humidity and the air speed in the smart home system, then inputs the collected temperature, humidity and air speed into the PMV model, the obtained PMV value is 3, the actually set PMV setting range is-0.5 to 0.5, and since 3 exceeds the setting range, an instruction for acquiring the current geographical location information and the current date information is triggered.

The acquisition device acquires geographical position information, and specifically, the geographical position information can be acquired through a GPS module.

The geographical location information, taking china as an example, can divide the geographical area of china into 7 geographical areas according to the climate characteristics, which are:

in Central China: henan province, Hubei province, Hunan province;

in North China: beijing City, Tianjin City, Shanxi province, Hebei City, inner Mongolia autonomous region;

in the east China: shanghai city, Jiangsu province, Zhejiang province, Anhui province, Fujian province, Jiangxi province, Shandong province, Taiwan province;

in the south China: guangdong province, Hainan province, Guangxi Zhuang autonomous region, hong Kong special administrative region, and Macau special administrative region;

in the northwest region: shanxi province, Gansu province, Qinghai province, Ningxia Hui autonomous region, Xinjiang Uygur autonomous region;

in the northeast region: heilongjiang province, Jilin province, Liaoning province;

in the southwest region: chongqing city, Sichuan province, Guizhou province, Yunnan province and Tibet autonomous region.

The current date information may be the system time of the device, representing the current climate, such as spring, summer, fall, and winter.

After the current geographic position information and the current date information are obtained, comfort degree adjusting values used for representing that comfort degrees of human bodies are influenced in different areas and different times are determined according to the current geographic position information and the current date information.

The comfort adjustment value is used for representing that the comfort of the human body is influenced in different areas and different time. For example, in north China, if the area is cold and dry in winter and is accompanied by strong wind, the humidity and the air speed need to be adjusted.

Specifically, when the comfort level adjustment value is determined, an adjustment function is determined, an adjustment coefficient corresponding to the adjustment function is determined, and finally, the product of the adjustment function and the adjustment coefficient is used as the comfort level adjustment value.

Determining an adjusting function, namely determining a human body comfortable environment parameter at first, then determining an environment change coefficient corresponding to the human body comfortable environment parameter, and finally determining the adjusting function according to the current environment parameter, the human body comfortable environment parameter and the environment transformation coefficient.

Before determining the human body comfortable environment parameters, presetting the binding relationship of the geographic position information, the date information and the human body comfortable environment parameters, and then determining the human body comfortable environment parameters corresponding to the current geographic position information and the current date information according to the binding relationship.

The human body comfortable environment parameters can be obtained by acquiring a large amount of geographical position information and date information and then obtaining the human body comfortable environment parameters corresponding to each geographical position information and each date information through experiments.

It should be noted that the human body comfort environment parameter in the embodiment of the present invention may be some or all of the following: a human body comfortable temperature parameter, a human body comfortable humidity parameter and a human body comfortable air flow rate parameter.

The current environmental parameters are some or all of the following: a current temperature parameter, a current humidity parameter, and a current air flow rate parameter.

The human comfortable environment parameter and the current environment parameter are in one-to-one correspondence, namely the human comfortable temperature parameter corresponds to the current temperature parameter, the human comfortable humidity parameter corresponds to the current humidity parameter, and the human comfortable air flow rate parameter corresponds to the current air flow rate parameter.

Current temperature parameter, current humidity parameter and current air flow rate parameter can be that indoor smart machine sends after gathering and gives the equipment of adjusting to the PMV value, also can be that the equipment self that adjusts is carried out to the PMV value gathers, can also be that other equipment gather, then send the equipment of adjusting to the PMV value.

In order to intuitively represent the binding relationship between the geographic location information, the date information, and the human body comfort environment parameters, the following table is used as an example for explanation.

Table 6 is a table of binding relationships between geographical location information, date information, and human body comfort temperature parameters provided in the embodiment of the present invention.

TABLE 6

It should be noted that the data in table 6 are only used for reference, and the specific implementation may be determined according to actual situations.

Table 6 is a table of binding relationships between the geographical location information, the date information, and the human body comfortable temperature parameter, and the binding relationships between the geographical location information, the date information, and the human body comfortable humidity parameter, the binding relationships between the geographical location information, the date information, and the human body comfortable air flow rate parameter are similar to table 6, which is not illustrated here.

And after the human body comfortable environment parameter is obtained, determining an environment change coefficient corresponding to the current environment parameter and the human body comfortable environment parameter according to the binding relationship among the current environment parameter, the human body comfortable environment parameter and the environment change coefficient.

Determining the environment variation coefficient can be divided into three different ways, which are described below.

In the first mode, the human body comfort environmental parameters comprise human body comfort temperature parameters, the environmental parameters comprise current temperature parameters, and the environmental change coefficient is a temperature change coefficient.

Determining the binding relationship of the temperature change coefficient as follows: the binding relation of the temperature parameter, the human body comfortable temperature parameter and the temperature change coefficient.

In order to make the binding relationship more intuitive, the following description is in the form of a table.

Table 7 is a table showing a binding relationship among the temperature parameter, the human body comfort temperature parameter, and the temperature change coefficient according to the embodiment of the present invention.

In Table 7, b1 is the temperature variation coefficient, t1 is the current temperature parameter, and the unit is; t2 is a human body comfort temperature parameter in units of ℃. The human body comfortable temperature parameter t2 is the current position and the current season body feeling comfortable temperature, and can be obtained through a large number of experiments.

TABLE 7

It should be noted that the temperature adjustment coefficients in table 7 are only examples, and may be determined according to actual situations.

And in the second mode, the human body comfortable environment parameters comprise human body comfortable humidity parameters, the current environment parameters comprise current temperature parameters and current humidity parameters, and the environment change coefficient is a humidity change coefficient.

Determining the binding relationship of the humidity change coefficient as follows: the current temperature parameter, the current humidity parameter, the human body comfortable humidity parameter and the humidity change coefficient.

Since the most important factor affecting the comfort of human body is temperature, the coefficient of variation of humidity is related to temperature parameters as well as humidity parameters and human body comfort humidity parameters.

With reference to the above example of determining the temperature change coefficient, no further example is repeated here for determining the binding relationship of the humidity change coefficient.

And in the third mode, the human body comfortable environment parameters comprise human body comfortable air flow rate parameters, the current environment parameters comprise current temperature parameters and current air flow rate parameters, and the environment variation coefficient is an air flow rate variation coefficient.

Determining the binding relationship of the air flow velocity variation coefficient as follows: the current temperature parameter, the current air flow rate parameter, the human body comfortable air flow rate parameter and the air flow rate variation coefficient.

Since the most important factor affecting the comfort of the human body is the temperature, the variation coefficient of the air flow rate is related to the temperature parameter in addition to the current air flow rate parameter and the comfortable air flow rate parameter of the human body.

With reference to the above example of determining the temperature variation coefficient, no further example is repeated here for determining the binding relationship of the air flow rate variation coefficient.

After the human body comfortable environment parameter and the environment change coefficient are determined, an adjusting function is determined according to the current environment parameter, the determined human body comfortable environment parameter and the determined environment change coefficient. The environment parameter can be the temperature parameter, also can be the humidity parameter, still can be air velocity parameter, the comfortable environment parameter of human body can be human comfortable temperature parameter, also can be human comfortable humidity parameter, still can be human comfortable air velocity parameter, and environment parameter and the corresponding of human comfortable environment parameter, that is to say, temperature parameter and human comfortable temperature parameter correspond, humidity parameter and human humidity parameter correspond, air velocity parameter and human comfortable air velocity parameter correspond, divide three kinds of modes below to explain how to confirm the regulatory function.

In the first mode, if the current environment parameter is a current temperature parameter and the human body comfortable environment parameter is a human body comfortable temperature parameter, the current temperature parameter and the human body comfortable temperature parameter are subjected to difference, and the obtained difference value is multiplied by a temperature change coefficient to obtain a temperature adjustment function.

For example, if the current temperature parameter is t1, the human body comfort temperature parameter is t2, and the temperature variation coefficient is b1, the temperature adjustment function f1(t1, t2) is:

f1(t1,t2)＝(t1-t2)*b1

and secondly, if the current environment parameter is a current humidity parameter and the human body comfortable environment parameter is a human body comfortable humidity parameter, subtracting the current humidity environment parameter from the human body comfortable humidity parameter, quoting the absolute value of the difference value and the difference value to obtain a relative environment parameter, and finally taking the product of the relative environment parameter and the humidity change coefficient as a humidity adjusting function.

For example, if the current temperature is t1, the current humidity parameter is rh1, the human body comfort humidity parameter rh2 and the humidity variation coefficient is b2, the humidity adjustment function f2(t1, rh1 and rh2) is:

f2(t1,rh1,rh2)＝(rh1-rh2)/abs(rh1-rh2)*b2

and thirdly, if the current environment parameter is a current air flow rate parameter and the human body comfortable environment parameter is a human body comfortable air flow rate parameter, subtracting the current air flow rate parameter from the human body comfortable air flow rate parameter, then quoting the absolute value of the difference value and the difference value to obtain a relative air flow rate parameter, and finally taking the product of the relative air flow rate parameter and the air flow rate variation coefficient as an air flow rate adjusting function.

For example, when the current temperature is t1, the current air flow parameter is v1, the human comfort air flow parameter is v2, and the variation coefficient of the air flow rate is b3, the air flow rate adjustment function f3(t1, v1, v2) is:

f3(t1,v1,v2)＝(v1-v2)/abs(v1-v2)*b3

after the adjustment function is determined, an adjustment coefficient may be determined according to the current human body comfort environment parameter, the current geographic location information, and the current date information, specifically, a binding relationship between the geographic location information, the date information, and the adjustment coefficient is preset, and then the adjustment coefficient corresponding to the current geographic location information and the current date information is determined according to the binding relationship.

The adjustment coefficient in the embodiment of the present invention is 1 or 0, if adjustment is required, the adjustment coefficient is 1, and if adjustment is not required, the adjustment coefficient is 0.

For example, the geographical location information is the north China area, the date information is the winter, and since the north China area is cold and dry in winter and is accompanied by strong wind, the humidity and the air speed need to be adjusted, the humidity adjustment coefficient is 1, the air speed adjustment coefficient is 1, and the temperature adjustment coefficient is 0.

Assuming that the adjustment function is f (α 1, α 2, α 3), the comfort adjustment value is

The comfort level adjustment value is used to adjust the PMV value, which is Δ PMV + Δ after adjustment.
