Detailed Description

Embodiments of the present invention will be described in detail below, the embodiments described with reference to the drawings being illustrative, and the embodiments of the present invention will be described in detail below.

The embodiment of the invention takes the PMV (Predicted Mean volume) as the basis, and controls the air conditioner by combining the indoor temperature or the relative humidity, and compared with singly reflecting the comfort through the temperature, the PMV value can more accurately and dynamically reflect the real comfort of the human body, and reflects the real feeling of the human body to the temperature, the humidity and the wind. When the PMV value is between-0.5 and 0.5, the human body is considered to be in an A-level comfortable interval, the central value is 0.0, and the indoor temperature and the relative humidity are jointly controlled according to the PMV value, so that the air conditioner can accurately adjust the indoor comfort level according to the set PMV value, the comfort level of the indoor environment is improved, and the comfort experience of a user is improved.

Specifically, the definition of PMV is: taking a basic equation of human body heat balance and the grade of psychophysiological subjective heat sensation as starting points, considering comprehensive evaluation indexes of relevant factors such as human body heat sensation and comfort sensation, and the PMV index shows the average index of a group for seven grades, such as seven grades (-3- +3) of heat sensation voting. Generally, when the PMV value is between-0.5 and 0.5, the human body is in the A-level comfortable interval.

In the embodiment of the present invention, the calculation function of the PMV is PMV ═ f (Ta, Va, Rh, T τ, M, cIo), and it can be seen from the function that the PMV is calculated by 4 environmental factors and 2 human factors, where the 4 environmental factors, such as air temperature Ta, relative humidity Rh, air wind speed Va, average radiation temperature T τ, and 2 human factors, such as human metabolic rate M and clothing thermal resistance clo, get the PMV value by substituting the 4 environmental factors and the 2 human factors into the calculation function of the PMV. Since the average radiation temperature T τ is the air temperature Ta detected by the air conditioner, the air temperature Ta is the indoor temperature, and the relative humidity Rh is the humidity detected by the air conditioner; the air speed is set to be Va 0.1m/s, if the air conditioner is started with the direct blowing prevention function, the air conditioner is set to be low wind, the wind guide mechanism of the air conditioner controls the wind outlet airflow to follow the ceiling, the cold air density is high, the principle of sedimentation is utilized, the patio airflow is achieved, and at the moment, the air speed of the air conditioner is considered to be breeze or ultralow breeze airflow. Thus, the complex function of PMV ═ f (Ta, Va, Rh, T τ, M, cIo) is simplified to the known air temperature Ta and humidity Rh, and the simple function of PMV value, i.e., the function of PMV ═ f (Ta, Rh), is solved. Therefore, the analytic function of the PMV is converted into a three-dimensional array list, and engineering application is facilitated.

However, in practical applications, the air outlet of the air conditioner is not always blown out at a very low outlet air speed when the air conditioner is turned off, for example, when the air conditioner is turned off to prevent direct blowing, the current air speed Va is also an important factor influencing the PMV value, for example, when the current air speed Va is greater than 0.2M/s, the PMV is simplified into a complex function of f (Ta, Va, Rh, tt, M, cIo) by considering the influence of the air speed Va, the air temperature Ta and the relative humidity Rh on the PMV value, and the standard effective temperature SET is solved by solving the known air temperature Ta, humidity Rh and air speed Va^*I.e., PMV ═ f (Ta, Rh, Va).

It can be seen that the PMV can reflect the average index of the population to the thermal sensation level in consideration of the factors of temperature, humidity, wind speed and the like, and is closer to the real comfortable feeling of the human body compared with the single temperature-based comfort response, and is the real feeling of the human body to the temperature, the relative humidity and the wind speed. Therefore, when the relative humidity in the air is low, the human body feels drier even if the temperature is relatively high. From this, through introducing PMV, control indoor temperature and relative humidity, can accurate regulation indoor comfort level to, improve the comfort level of indoor environment, improve user's comfort and experience.

A method for controlling an air conditioner according to an embodiment of the present invention will be described below.

A control method of an air conditioner according to an embodiment of the present invention is described below with reference to fig. 1, and as described in fig. 1, the control method of an air conditioner of an embodiment of the present invention includes at least steps S1 through S4.

And step S1, acquiring the set PMV value, the set relative humidity and the current air speed of the air conditioner.

In an embodiment, a PMV value is set, e.g. a target PMV set by the user according to a thermal sensing requirement, e.g. noted PMV _ s. Specifically, the user may input the set PMV value of the air conditioner, for example, to 0.0, i.e., PMV _ s is 0.0, through, but not limited to, an air conditioner remote controller or an associated key on an operation interface on the air conditioner body. In the operation process of the air conditioner, the air outlet of the air conditioner is blown to the area where the user is located, and the air outlet is not blown at a very low air outlet speed, and the influence of the air outlet speed of the air conditioner on the set PMV value needs to be considered, so that the current air speed needs to be acquired, and is recorded as Va, for example.

And, the user inputs the set relative humidity according to the actual demand and sensitivity to the relative humidity, for example, Rhs, it is understood that the set relative humidity Rhs may be inputted, and the current season or the operation mode of the air conditioner may be considered, because the operation mode selected by the air conditioner is different in different seasons.

For example, in summer, the air conditioner is generally operated in the cooling mode, and the set relative humidity may be set to 55%, that is, Rhs is 55%. If the user does not set the relative humidity, the default set relative humidity Rhs for the air conditioner is 55%. In winter, the air conditioner generally operates in a heating mode, and the set relative humidity may be set to 45%, that is, Rhs is 45%. If the user does not set the relative humidity, the default set relative humidity Rhs for the air conditioner is 40%. Therefore, the set PMV value, the set relative humidity Rhs and the current air speed Va are determined, and the set PMV value, the set relative humidity Rhs and the current air speed Va are used as control parameters of the subsequent air conditioner control process. It can be understood that the PMV value is set as a function operation value, the PMV value is not directly detected by the air conditioner, and the air conditioner can be controlled by setting the PMV value to reflect the comfort requirement of the user more truly and accurately, so that the indoor comfort can be adjusted accurately.

The set PMV value and the set humidity Rhs are used as control parameters of the subsequent air conditioner control process, so that the indoor comfort level can be accurately adjusted, and the real comfort level requirement of a user can be met.

And step S2, determining the corresponding reference air temperature when the wind speed is lower than the preset wind speed threshold value according to the set PMV value and the set relative humidity.

In the embodiment, the reference air temperature is the air temperature calculated by a look-up table or a function according to the set relative humidity Rhs and the set PMV value when the current air wind speed Va is 0.1 m/s. It will be appreciated that the reference air temperature may be determined based on the set relative humidity Rhs and the set PMV value, taking into account the current season or operating mode of the air conditioner, since the air conditioner may select an operating mode that is different during different seasons and, therefore, the resulting reference air temperature.

For example, in summer, the human body metabolic rate M is 1.2, the clothing thermal resistance clo is 0.5, and the air conditioner generally operates in a cooling mode, in which the set PMV value is related to the indoor temperature Ta, the set relative humidity Rhs, and the current air speed Va, i.e., the PMV value f (Ta, Rhs, Va), but when the air temperature Ta, the relative humidity Rhs, and the air speed Va are substituted into the calculation formula of the set PMV value, the calculation process is complicated, and therefore, the set PMV value f (Ta, Rhs, Va) is equivalently converted into PMV value f ((Ta1, Rhs), where Ta1 is the reference air temperature corresponding to the current air speed Va of 0.1M/s when the air conditioner is cooling.

In winter, the human body metabolic rate M is 1.2, the clothing thermal resistance clo is 1.0, the air conditioner is generally operated in a heating mode, and for the same reason, the set PMV value f (Ta, Rhs, Va) is equivalently converted into PMV value f (Ta2, Rhs), where Ta2 is the reference air temperature when the current air speed Va is 0.1M/s when the air conditioner is heating. It can be known from the calculation formula of the set PMV value after the equivalent conversion that when the current air speed Va is 0.1m/s, the corresponding reference air temperature when the air speed is lower than the preset air speed threshold value can be determined according to the set PMV value and the set relative humidity Rhs, where the preset air speed threshold value is, for example, 0.2m/s, and when the air speed is lower than 0.2m/s, such as 0.1m/s, the air speed at the air outlet of the air conditioner is considered to be a breeze or ultra-low breeze airflow, such as when the air conditioner direct blow prevention function is turned off. Specifically, as can be known from the calculation formula of the set PMV value after the equivalent conversion, when the current air wind speed Va is determined, the reference air temperature corresponding to the reference air temperature (specifically, the wind speed is 0.1m/s) corresponding to the wind speed lower than the preset wind speed threshold is determined according to the set PMV value and the set relative humidity Rhs.

For example, in summer, when the human body metabolic rate M is 1.2 and the clothing thermal resistance clo is 0.5, and when the air conditioner is cooling, and when the set PMV value is 0.0 and the target relative humidity Rhs is 55%, the reference air temperature Ta1 is determined to be 27 ℃, that is, Ta1 is 27 ℃ by a table lookup or a function calculation method.

In winter, when the human body metabolic rate M is 1.2 and the clothing thermal resistance clo is 1.0, and when the air conditioner heats, the set PMV value is 0.0 and the target relative humidity Rhs is 45%, the reference air temperature Ta2 is 22.5 ℃, that is, Ta2 is 22.5 ℃ by a table lookup or function calculation method.

And step S3, determining the target indoor temperature according to the reference air temperature and the current air wind speed.

In the embodiment, the target indoor temperature is, for example, denoted as Ts, and it is understood that the target indoor temperature Ts is determined in relation to the reference air temperature and the current air wind speed Va, and when the reference air temperature is determined, the target indoor temperature Ts is determined according to the current air wind speed Va and the reference air temperature.

And substituting the air wind speed Va and the reference air temperature into a calculation formula of the target indoor temperature Ts to obtain corresponding second target environmental parameters under different current air wind speeds Va.

For example, in summer, when the air conditioner is cooling, the reference air temperature Ta1 is 25.5 ℃ and the current air temperature Va is 0.3m/s, the target indoor temperature Ts is 27 ℃ based on the reference air temperature Ta1 and the current air speed Va.

In winter, when the air conditioner heats, the reference air temperature Ta2 is 22.5 ℃ and the current air temperature Va is 0.42m/s, and the target indoor temperature Ts is 24 ℃ according to the reference air temperature Ta2 and the current air speed Va.

And step S4, controlling the air conditioner to operate according to the set relative humidity and the target indoor temperature.

In the embodiment, the determination of the set relative humidity Rhs and the target indoor temperature Ts is related to the set PMV value, after the determination of the set relative humidity Rhs and the target indoor temperature Ts, the air conditioner is controlled based on the set relative humidity Rhs and the target indoor temperature Ts, so that the common control of the temperature and the humidity is realized, the air conditioner can operate according to the set PMV value, the actual indoor PMV value can reach the set PMV value, the actual indoor comfort level can meet the real comfort level requirement of a user, and the comfort level experience of the user is improved. It can be understood that the operation of the air conditioner is controlled based on the target relative humidity Rhs and the target indoor temperature Ts, the influence of the temperature and the humidity on the indoor environment is considered, and compared with single temperature control, the indoor comfort degree can be accurately adjusted, so that the comfort degree of the indoor environment is improved, and the requirement of a human body on the comfort degree is met.

According to the control method of the air conditioner, the PMV value and the relative humidity Rhs are set to determine the corresponding reference air temperature when the wind speed is lower than the preset wind speed threshold, the target indoor temperature Ts is determined according to the reference air temperature and the current air wind speed Va, the set relative humidity Rhs and the target indoor temperature Ts are used as control parameters to control the operation of the air conditioner, the common control of the indoor temperature Ta and the relative humidity Rh is realized, the air conditioner can accurately adjust the indoor comfort level according to the set PMV value, the problem that the real comfort level of a user is poor in feeling due to the fact that the relative humidity Rh is higher or lower when the indoor temperature Ta is proper is solved, and therefore the comfort level of the indoor environment is improved, and the comfort experience of the user is improved.

In some embodiments, determining the target indoor temperature from the reference air temperature and the current air wind speed Va includes: when the air conditioner is used for refrigerating, inputting the current air speed Va into a first preset reference air temperature compensation empirical function to obtain a reference air temperature compensation value, or when the air conditioner is used for heating, inputting the current air speed Va into a second preset reference air temperature compensation empirical function to obtain a reference air temperature compensation value; the sum of the reference body air temperature compensation value and the reference air temperature is taken as the target indoor temperature Ts.

It is understood that the reference air temperature compensation empirical function is an air temperature compensation empirical function based on the reference air temperature, for example, denoted as f (va). Specifically, when the air conditioner is used for cooling, the corresponding reference air temperature compensation empirical function is a first preset reference air temperature compensation empirical function, that is, f (Va) is 6.25 × Va-0.54, and the unit is ° c, it can be seen that f (Va) is a function related to the current air speed Va, and when the current air speed Va is determined, the current air speed Va is substituted into f (Va), that is, the reference air temperature compensation value is obtained. For example, when the current air speed Va is 0.3m/s, it is substituted into f (Va), that is, f (Va) is 6.25 × 0.30+0.54 ≈ 1.5 ℃.

When the air conditioner heats, the corresponding reference air temperature compensation empirical function is a second preset reference air temperature compensation empirical function, that is, f (Va) ═ 5.7 × Va-0.59, and the unit is ° c, it can be seen that f (Va) is a function related to the current air wind speed Va, and when the current air wind speed Va is determined, the current air wind speed Va is substituted into f (Va), that is, the reference air temperature compensation value can be obtained. For example, when the current air speed Va is 0.42m/s, it is substituted into f (Va), that is, f (Va) is 5.7 × 0.42-0.9 ≈ 1.5 ℃.

Further, after the reference air temperature compensation value is determined, the sum of the reference body air temperature compensation value and the reference air temperature is calculated as the target indoor temperature Ts. Specifically, when the air conditioner is cooling, it can be known from a calculation formula of the target indoor temperature Ts, that is, Ts ═ Ta1+ f (va), that the target indoor temperature Ts, the reference air temperature Ta1, and the first preset reference air temperature compensation empirical function satisfy a certain functional relationship, and when the reference air temperature compensation value and the reference air temperature Ta1 are determined, the target indoor temperature Ts is determined accordingly, for example, when the reference air temperature compensation value is 1.5 ℃, the reference air temperature Ta1 is 25.5 ℃, and the target indoor temperature Ts is 25.5 ℃ +1.5 ℃ ═ 27 ℃;

when the air conditioner heats, the target indoor temperature Ts is calculated according to the formula, that is, Ts is Ta2+ f (va), and it can be seen that the target indoor temperature Ts, the reference air temperature Ta2 and the second preset reference air temperature compensation empirical function satisfy a certain functional relationship, and when the reference air temperature compensation value and the reference air temperature Ta2 are determined, the target indoor temperature Ts is determined accordingly, for example, the reference air temperature compensation value is 1.5 ℃, the reference air temperature Ta2 is 22.5 ℃, and the target indoor temperature Ts is 22.5 ℃ +1.5 ℃ + 24 ℃. By calculating the reference air temperature compensation value and taking the sum of the reference air temperature compensation value and the reference air temperature as the target indoor temperature Ts, the accuracy of acquiring the target indoor temperature Ts is improved.

In some embodiments, the obtaining of the current air wind speed Va includes: acquiring the current gear of an indoor fan and the current position state of a transverse air deflector; when the air conditioner is used for refrigerating, according to the current gear of the indoor fan and the current position state of the transverse air deflector, inquiring a mapping table of the corresponding relation between the gear of the first preset indoor fan, the position state of the transverse air deflector and the wind speed to obtain the corresponding current air wind speed Va; when the air conditioner heats, according to the current gear of the indoor fan and the current position state of the transverse air deflector, inquiring a mapping table of the corresponding relation of the gear of the second preset indoor fan, the position state of the transverse air deflector and the wind speed to obtain the corresponding current air wind speed Va; the first preset indoor fan gear-transverse air deflector position state-wind speed corresponding relation mapping table and the second preset indoor fan gear-transverse air deflector position state-wind speed corresponding relation mapping table respectively comprise corresponding relations among a plurality of groups of indoor fan gears-transverse air deflector position states-wind speeds.

In a specific embodiment, when the air conditioner is cooling, as shown in fig. 2, it is a schematic view of a current position state of the transverse air guiding plate according to an embodiment of the present invention. As can be seen from fig. 2, the current position status of the transverse air guiding plate when the air conditioner is cooling includes position 1-position 5, and the sweeping status of the circulating sweeping between position 1-position 5 (not shown in the figure). The positions 1 to 5 are angles of specific positions of the transverse air guiding plate, the positions are different, the angles of the positions of the corresponding transverse air guiding plates are different, and the sweeping state is an operation state of the transverse air guiding plate, for example, the transverse air guiding plate is in an up-down sweeping operation state, so that 6 position angles or states are presented in total. And, indoor fan generally includes a plurality of gears, like high wind gear, well wind gear and low wind gear etc. and the wind speed that different gears correspond is different. Therefore, the indoor fans are in different gears and different positions of the transverse air guide plates, multiple combinations exist, current air speeds Va corresponding to different combinations are different, average air speeds of corresponding user areas are also different, accordingly, the air speeds blowing to the exposed skin of the user are also different, and actual indoor temperatures sensed by the user are also obviously different.

For example, when the air conditioner is cooling, as shown in table 1, it is a mapping table of correspondence relationship between a first preset indoor fan gear, a position state of a transverse air guiding plate, and a wind speed according to an embodiment of the present invention.

Table 1 mapping table of correspondence relationship between first preset indoor fan gear position-transverse air deflector position state-wind speed

As can be seen from table 1, when the current gear of the indoor fan and the current position state of the transverse air deflector are known, the current air speed Va can be determined by looking up a table, for example, when the current gear of the indoor fan is a middle gear, and the current position state of the transverse air deflector is position 4, the current air speed Va can be determined to be 0.3m/s by looking up a table 1; for another example, the user adjusts the transverse air deflector to be at position 1, and the current gear of the indoor fan is a medium wind gear, and the current air speed Va can be determined to be 0.2m/s by looking up table 1; for another example, the current gear of the indoor fan is the high wind gear, the horizontal air guiding plate is adjusted to the position 5, and the current air speed Va can be determined to be 0.40m/s by looking up the table 1. The gear of the indoor fan and the current position state of the transverse air deflector are obtained, and the current air speed Va is obtained through table lookup, so that the determination process of the front air speed Va is more convenient and accurate, and the target indoor temperature Ts can be accurately determined.

In an embodiment, when the air conditioner heats, as shown in fig. 3, it is a schematic view of a current position state of the transverse air guiding plate according to an embodiment of the present invention. As can be seen from fig. 3, the current position status of the transverse air guiding plate includes positions 6-10, and a sweeping status (not shown) of the cyclic sweeping between positions 6-10 when the air conditioner is heating. The positions 6 to 10 are angles of specific positions of the transverse air guiding plate, the positions are different, the angles of the positions of the corresponding transverse air guiding plates are different, and the sweeping state is an operation state of the transverse air guiding plate, for example, the transverse air guiding plate is in an up-down sweeping operation state, so that 6 position angles or states are presented in total. And, indoor fan generally includes a plurality of gears, like high wind gear, well wind gear and low wind gear etc. and the wind speed that different gears correspond is different. Therefore, the indoor fans are in different gears and different positions of the transverse air guide plates, multiple combinations exist, current air speeds Va corresponding to different combinations are different, average air speeds of corresponding user areas are also different, accordingly, the air speeds blowing to the exposed skin of the user are also different, and actual indoor temperatures sensed by the user are also obviously different.

For example, when the air conditioner heats, as shown in table 2, it is a mapping table of the second predetermined indoor fan gear-transverse air guiding plate position state-wind speed correspondence relationship according to an embodiment of the present invention.

Table 2 mapping table of correspondence relationship between second preset indoor fan gear position-transverse air guiding plate position state-wind speed

As can be seen from table 2, when the current gear of the indoor fan and the current position state of the transverse air guiding plate are known, the current air speed Va can be determined by looking up a table, for example, when the current gear of the indoor fan is the high gear, and the current position state of the transverse air guiding plate is position 7, the current air speed Va can be determined to be 0.42m/s by looking up table 2. The gear of the indoor fan and the current position state of the transverse air deflector are obtained, and the current air speed Va is obtained through table lookup, so that the determination process of the front air speed Va is more convenient and accurate, and the target indoor temperature Ts can be accurately determined.

In some embodiments, determining the reference air temperature corresponding to the wind speed lower than the preset wind speed threshold according to the set PMV value and the set relative humidity comprises: and inputting the set PMV value and the set relative humidity Rhs into a preset parameter function relation of the set PMV value, the relative humidity and the reference air temperature to obtain the reference air temperature. Specifically, there is a functional correspondence between the set PMV value, the set relative humidity Rhs, and the reference air temperature, for example, PMV ═ f (Ta1, Rhs), and it can be seen that the reference air temperature Ta1 can be obtained by calculation by substituting the set PMV value and the set relative humidity Rhs into the functional relation. For example, in summer, the clothing thermal resistance clo is 0.5, the human body metabolic rate M is 1.2, and when the air conditioner is cooling, the set PMV value of 0 and the set relative humidity Rhs of 50% are substituted into the above function calculation formula, and the reference air temperature Ta1 is 25.5 ℃, that is, Ta1 is 25.5 ℃. For example, in winter, the clothing thermal resistance clo is 1.0, the human body metabolic rate M is 1.2, and at this time, when the air conditioner is heating, the set PMV value is 0 and the set relative humidity Rhs is 45% are substituted into the above function calculation formula, and the reference air temperature Ta2 is 22.5 ℃, that is, Ta2 is 22.5 ℃.

In some embodiments, determining the reference air temperature corresponding to the wind speed below the predetermined wind speed threshold based on the set PMV value and the set relative humidity Rhs includes: when the current summer is detected, the reference air temperature is obtained by inquiring a first preset PMV value-relative humidity-reference air temperature parameter corresponding relation mapping table; when the current situation in winter is detected, the reference air temperature is obtained by inquiring a second preset PMV value-relative humidity-reference air temperature parameter corresponding relation mapping table; the first preset PMV value-relative humidity-reference air temperature parameter corresponding relation mapping table and the second preset PMV value-relative humidity-reference air temperature parameter corresponding relation mapping table respectively comprise corresponding relations among a plurality of groups of PMV values, relative humidity and reference air temperature parameters. It can be understood that the thermal resistance of the garment is different in different seasons, for example, the thermal resistance clo of the garment is 0.5 in summer, and the thermal resistance clo of the garment is 1.0 in winter, which is a value that affects PMV and thus affects the corresponding reference air temperature. Therefore, the mapping tables of the correspondence relationship between the PMV value-relative humidity-reference air temperature parameter corresponding to the winter and summer are also different, so that in the embodiment of the invention, in summer, the mapping table of the correspondence relationship between the first preset PMV value-relative humidity-reference air temperature parameter is inquired to obtain the reference air temperature; and in winter, inquiring a second preset PMV value-relative humidity-reference air temperature parameter corresponding relation mapping table to obtain the reference air temperature.

It can be understood that there is a corresponding relationship among the set PMV value, the set relative humidity Rhs and the reference air temperature parameter, and any two of them are determined, and the other parameter can be obtained by looking up the table. Of course, in the specific embodiment, when two parameters are determined, another parameter may be obtained by performing an operation as a function of PMV ═ f (Ta, Rh). The preset map of correspondence relationship between PMV value-relative humidity-reference air temperature parameter is obtained by calibration according to a large amount of test data, for example, a large amount of data of correspondence relationship between PMV value-relative humidity-reference air temperature parameter is obtained by decoupling according to a function of PMV ═ f (Ta, Rh), and then the preset map of correspondence relationship between PMV value-relative humidity-reference air temperature parameter is obtained by calibration.

In a specific embodiment, the manner of detecting the current season may include: determining the current season according to the current environmental parameters; and/or synchronously determining the current season according to the season information displayed by the intelligent terminal.

The following is a description of the determination of the reference air temperature when determining the set PMV value and the set relative humidity Rhs.

Specifically, as shown in table 3, when the air conditioner is cooling in summer, the map is an example of the first predetermined PMV value-set relative humidity-reference air temperature parameter correspondence table according to an embodiment of the present invention. Wherein, the human body metabolic rate M and the clothing thermal resistance clo are respectively 1.2 and 0.5.

A corresponding inverse operation is Ta ═ f (Rh, PMV), and thus can be converted to: ta1 is f (Rhs, PMV _ s), so that when the set relative humidity Rhs and the set PMV value are known, the corresponding reference air temperature Ta1 can be found. Of course, the corresponding reference air temperature Ta1 may also be obtained by looking up a table, for example, as shown in table 4, which is an example of a mapping table for querying the reference air temperature Ta1 according to the set relative humidity Rhs when the PMV value is set to 0.0 in an embodiment of the present invention.

Of course, the corresponding reference air temperature Ta2 may also be obtained by looking up a table, for example, as shown in table 6, which is an example of a mapping table for querying the reference air temperature Ta2 according to the set relative humidity Rhs when the PMV value is set to 0.0 in an embodiment of the present invention.

As can be seen from the above correspondence table, the set PMV value and the set relative humidity Rhs are known, and the reference air temperature can be obtained by calculation from a look-up table or a function, for example, the set PMV value is 0.0 and the target relative humidity Rhs is 45%, and the reference air temperature Ta2 is 22.5 ℃.

In other embodiments of the present invention, taking air conditioner cooling as an example, as shown in table 7, a mapping table of the correspondence between the relative humidity and the reference air temperature is set for the set PMV value according to an embodiment of the present invention.

Table 7 map table for setting correspondence between relative humidity and reference air temperature

It is understood that the relative humidity range for human comfort is generally 35% -65%, therefore, the air conditioner generally controls the relative humidity to be 35% -65%, the first data is 35%, the last data is 65%, the target relative humidity Rhs is increased by a%, for example, where a may be 1,2, 5, 10, etc., and is determined by the accuracy of the humidity sensor, the amount of the calculated data, etc. The accuracy of the target indoor temperature is, for example, B.degree.C., e.g., 0.1 degree.C, 0.2 degree.C, 0.5 degree.C, 1 degree.C, and is determined by the accuracy of the temperature sensor, the amount of calculation data, and the like. The input set PMV value, e.g., 0.2, automatically generates data as in table 7, one set of which is set relative humidity Rhs and reference air temperature. In Table 7, n is 1,2, …, and m is 0,1,2 …. Due to the problem of the value precision of B, in practice, a plurality of set relative humidity values may correspond to 1 reference air temperature.

For example, setting the PMV value to be 0.3, when the precision of B is 0.5 ℃, A is increased according to 5%, and the relative humidity Rh is 50%, the corresponding reference air temperature is 26.8 ℃; when the relative humidity Rh is 55%, the corresponding reference air temperature is 27 ℃; when Rh is 60%, the corresponding reference air temperature is 27.2 ℃, and since the accuracy of the temperature sensor is 0.5 ℃, the target indoor temperature actually displayed is 27 ℃ after taking an integral multiple of 0.5.

Specifically, when the PMV value is set to 0.0, it is generally considered that the heat sensation requirement is moderate, but some users may feel that the current heat sensation is slightly cool when the set PMV value is 0 due to individual differences, and at this time, it is necessary to increase the set PMV value, that is, to adjust the set PMV value from 0.0 to about 0.3, analyze the data shown in table 8 from the set PMV value of 0.3, obtain the reference air temperature Ta1 from the set PMV value and the set relative humidity Rhs by means of the table look-up 8, for example, the set PMV value of 0.3 and the set relative humidity of Rhs to 50%, and obtain the reference air temperature Ta1 from the table look-up of 26.5 ℃.

In other embodiments, if the user adjusts the set PMV value and/or sets one or more of the relative humidity Rhs and the current air speed Va, the target indoor temperature Ts is determined again, and the indoor temperature Ta and the relative humidity Rh are controlled according to the new target indoor temperature Ts and/or the set relative humidity Rhs, so that the operation of the air conditioner is adjusted and controlled in time, the indoor comfort level is adjusted in time, the comfort level requirement of the user is met in time, the comfort level experience of the user is improved, and the reliability of the air conditioner is also improved.
