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.

Embodiments of the invention use SET^*(Standard effective temperature), also called sensible temperature, is combined with indoor temperature or relative humidity to control the air conditioner, and compared with the Standard effective temperature SET which reflects comfort only through temperature^*The real comfort of the human body can be more accurately and dynamically reflected, and the real feeling of the human body to temperature, humidity and wind is reflected. Thus, according to the standard effective temperature SET^*Realize the common control of the indoor temperature and the relative humidity, so that the air conditioner can be controlled according to the indoor temperature and the relative humidityAccording to setting for the body temperature to come accurate indoor comfort level of adjusting to, improve the comfort level of indoor environment, improve user's comfortable nature and experience.

Standard effective temperature SET^*Is defined as: a person wearing a standard garment (with the thermal resistance of 0.6clo) is in an environment with the relative humidity of 50 percent and the approximately static air, namely the air speed of approximately 0.1m/s, the air temperature of the environment is the same as the average radiation temperature and the metabolic rate of 1met (equivalent to a static sitting posture), if the average skin temperature and the skin humidity at the moment are the same as those under the conditions of a certain actual environment and the actual garment thermal resistance, the human body has the same heat dissipation capacity in the standard environment and the actual environment, and the air temperature of the standard environment is the standard effective temperature of the actual environment, namely SET^*。

In the embodiment of the present invention, the standard effective temperature SET^*Also called body-sensing temperature, standard effective temperature SET^*The calculation function of (a) is: SET^*F (Ta, Va, Rh, T τ, M, cIo). As can be seen from the function, the standard effective temperature SET^*The method is characterized by comprising the following steps of participating in calculation by 4 environmental factors and 2 human body factors, wherein 4 environmental factors such as air temperature Ta, relative humidity Rh, air wind speed Va and average radiation temperature T tau, and 2 human body factors such as human body metabolic rate M and clothing thermal resistance clo are calculated by bringing the 4 environmental factors and the 2 human body factors into a standard effective temperature SET^*To obtain a standard effective temperature value, i.e. SET^*The value is obtained. 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. Thereby, SET^*Simplifying the complex function of f (Ta, Va, Rh, T tau, M, cIo) into the known air temperature Ta and humidity Rh, and solving the standard effective temperature SET^*A simple function of, i.e. SET^*F (Ta, Rh).

It can be seen that the standard effective temperature considers factors such as temperature, humidity and wind speed, and is closer to the real comfortable feeling of the human body compared with the single temperature reflecting comfort, and is the real feeling of the human body to the temperature, the relative humidity and the wind speed. For example, in real life, when the air speed is SET to 0.1m/s, the indoor temperature Ta is 27 ℃ and the relative humidity Rh is 80%, the standard effective temperature SET is obtained by functional calculation^*At 29.2 ℃; and when the indoor temperature Ta is the same and the relative humidity is 40%, the corresponding standard effective temperature SET^*26.8 ℃ and a difference of 2.4 ℃ between them, from which the standard effective temperature SET can be seen^*More approximate to the real comfortable feeling of the human body. Therefore, when the relative humidity in the air is low, the human body feels drier even if the temperature is relatively high. Thereby, by introducing a standard effective temperature SET^*Indoor temperature and relative humidity are controlled, indoor comfort can be accurately adjusted, and therefore the comfort of an indoor environment is improved, and comfort experience of a user is improved.

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 2. As shown in fig. 1, the control method of the air conditioner according to the embodiment of the present invention includes at least step S1, step S2, step S3, and step S4.

And step S1, acquiring the set sensible temperature of the air conditioner and the current environmental parameters, wherein the environmental parameters comprise indoor temperature or relative humidity.

In an embodiment, the SET sensible temperature is, for example, a target sensible temperature SET by the user according to the comfort requirement, for example, SET^*S. Specifically, the user can input the SET sensible temperature of the air conditioner, for example, to be 26 ℃, through, but not limited to, a remote controller of the air conditioner or a related key on an operation interface on the body of the air conditioner, that is, SET^*S is 26 ℃. And, in the air conditioner operation process, the air conditioner accessible humidity transducer gathers relative humidity Rh, and accessible temperature sensor gathers indoor temperature Ta to will SET for body and feel temperature SET^*S and relative humidity Rh as subsequent emptyThe controller controls the control parameters of the process, or SETs the sensible temperature SET^*S and the indoor temperature Ta as control parameters for the subsequent air conditioner control process. It is understood that the temperature SET is SET to the body-sensing temperature SET^*S is a function operation value, is not directly detected by the air conditioner, and is obtained by setting the sensible temperature SET^*The air conditioner can be controlled by the s to truly and accurately reflect the requirement of a user on comfort, and further, the indoor comfort can be accurately adjusted.

Specifically, the current environmental parameter includes relative humidity Rh or indoor temperature Ta, and the SET sensible temperature SET^*S and the relative humidity Rh/the indoor temperature Ta are used as control parameters of the control process of the subsequent air conditioner, so that the indoor comfort level can be accurately adjusted, and the real comfort level requirement of a user can be met. In addition, the temperature SET is sensed in accordance with the SET sensible temperature SET^*S and indoor temperature Ta, and SET sensible temperature^*The process of controlling the air conditioner by using the relative humidity Rh is similar to that of the s, and the subsequent control process is described by taking the current environmental parameter as the relative humidity Rh as an example.

Step S2 is to determine a first target environmental parameter based on the set sensible temperature and the current environmental parameter.

In an embodiment, the determination of the first target environmental parameter is combined with the SET body-sensory temperature SET^*S is related to the current environmental parameter, and when the current environmental parameter is relative humidity Rh, the SET sensible temperature SET is SET^*S and Rh determine a first target environmental parameter, which is a target relative humidity, such as Rhs.

For example, in determining the SET body-sensed temperature SET^*When the current Rh is detected by the humidity sensor at 26 ℃, _ for example, when the Rh is 82%, the sensible temperature SET is SET according to the SET sensible temperature SET^*S and Rh determines the target relative humidity Rhs to be 65%, i.e., Rhs-65%.

Correspondingly, when the current environmental parameter is the indoor temperature Ta, the temperature SET is sensed according to the SET body^*S and the room temperature Ta determine a first target environmental parameter, at which timeOne target environmental parameter is the target indoor temperature, denoted as Ts, for example.

Step S3 is to determine a second target environmental parameter based on the set sensible temperature and the first target environmental parameter.

In an embodiment, the determination of the second target environmental parameter is combined with the SET body-sensory temperature SET^*S is related to a first target environmental parameter, and when the first target environmental parameter is target relative humidity Rhs, the temperature is SET according to the SET sensible temperature SET^*S and target relative humidity Rhs, and determining a second target environmental parameter by table lookup or function calculation, wherein the second target environmental parameter is target indoor temperature Ts.

For example, SET body-sensing temperature SET^*When the temperature is 26 ℃ and the target relative humidity Rhs is 65%, the target indoor temperature Ts is determined to be 25.4 ℃ by a table look-up method or a function calculation method, namely, the target indoor temperature Ts is 25.4 ℃.

Correspondingly, when the first target environment parameter is the target indoor temperature Ts, the sensible temperature SET is SET according to the SET sensible temperature^*S and a target indoor temperature Ts, and determining a second target environmental parameter by a look-up table or a function calculation, wherein the second target environmental parameter is a target relative humidity Rhs.

And step S4, controlling the air conditioner to operate according to the first target environmental parameter and the second target environmental parameter.

In an embodiment, the first target environmental parameter and the second target environmental parameter are both determined with the SET sensible temperature SET^*S is relevant, after the first target environmental parameter and the second target environmental parameter are determined, the air conditioner is controlled based on the first target environmental parameter and the second target environmental parameter, the common control of the temperature and the humidity is realized, and the air conditioner can SET the somatosensory temperature SET^*S operation to make the indoor actual body sensing temperature reach the SET body sensing temperature SET^*S, so that the actual indoor comfort level can meet the real comfort level requirement of the 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, while considering the influence of the temperature and humidity on the indoor environment, compared to a single temperatureAnd the indoor comfort degree can be accurately adjusted by controlling, 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 SET sensible temperature SET is obtained^*S and current environmental parameters, such as indoor temperature Ta or relative humidity Rh, to determine a first target environmental parameter, SET, based on a SET sensible temperature^*Determining a second target environment parameter by the _Sand the first target environment parameter, and controlling the operation of the air conditioner by taking the first target environment parameter and the second target environment parameter as control parameters to realize the common control of the indoor temperature Ta and the relative humidity Rh, so that the air conditioner can sense the temperature SET according to the SET somatosensory temperature^*The indoor comfort level is accurately adjusted by the aid of the s, the situation that the temperature is singly taken as a control target is avoided, when the indoor temperature Ta is appropriate, the real comfort level of a user is poor in feeling due to the fact that the relative humidity Rh is higher or lower is solved, accordingly, the comfort level of the indoor environment is improved, and the comfort experience of the user is improved.

In some embodiments, the temperature SET is sensed according to a SET body-sensing temperature^*S and the current environmental parameter, determining a first target environmental parameter, comprising: acquiring a SET corresponding to a SET sensible temperature^*A plurality of target environmental parameters of _; and taking the one with the value equal to the environmental parameter or smaller than the current environmental parameter and closest to the value of the current environmental parameter as the first target environmental parameter.

It will be appreciated that the same sensible temperature, possibly corresponding to a plurality of different sets of air temperatures Ta and relative humidities Rh,

in other words, a plurality of different SETs of air temperatures Ta and relative humidities Rh, which ultimately correspond to the standard effective temperature SET^*May be the same. For example, SET the standard effective temperature SET^*The air temperature Ta and the relative humidity Rh can correspond to 26.0 ℃, respectively, to 25.4 ℃ and 65%, respectively, or to 25.8 ℃ and 55%, respectively, 26.2 ℃ and 45%. Thereby, the SET sensible temperature SET is determined^*S, then the SET sensible temperature SET corresponding to the SET sensible temperature can be obtained^*S, e.g. multiple objectivesTarget relative humidity Rhs or a plurality of target indoor temperatures Ts. Further, the temperature SET can be sensed from the SET body temperature SET^*S corresponds to the first target parameter determined to be ultimately required, i.e., the ultimately required target relative humidity Rhs or the target indoor temperature Ts, among the plurality of target environmental parameters.

After determining the plurality of target environment parameters, the detected current environment parameters may be compared with the plurality of target environment parameters, if there is a target environment parameter having a value equal to that of the current environment parameter, the target environment parameter is used as a first target environment parameter, and if there is no target environment parameter having a value equal to that of the current environment parameter, a target environment parameter having a value smaller than that of the current target environment parameter and being closest to the current target environment parameter among the plurality of target environment parameters is used as the first target environment parameter.

Setting sensible temperature SET by taking environmental parameters as relative humidity for illustration^*When the temperature is 26 ℃, acquiring and setting body sensing temperature SET^*A plurality of target relative humidities Rhs corresponding to 26 ℃. Wherein each SET body sensing temperature SET^*S corresponds to a plurality of target relative humidities Rhs, e.g. SET body temperature SET^*SET sensible temperature SET at 26 deg.C^*The target relative humidity Rhs for 26 ℃ may be 35%, 65%, 55%, etc. Air conditioner for setting body sensing temperature SET^*During the operation process at 26 ℃, if it is detected that the current relative humidity is 35%, since the determined values of the target relative humidity Rhs, for example, 35%, 65%, and 55%, are equal to the current relative humidity 35%, selecting the value equal to the current relative humidity from the target relative humidities Rhs as the first target environmental parameter, that is, the first target environmental parameter is 35%; if it is detected that the current relative humidity is 82%, because there is no one with the same relative humidity as the current relative humidity among the determined values of the target relative humidities Rhs, selecting 65% which is the closest to the current relative humidity and is smaller than the current relative humidity from the target relative humidities Rhs as a first target environmental parameter, that is, the value of the first target environmental parameter is 65%, that is, the finally required target relative humidity Rhs;for another example, when the current relative humidity is detected to be 59%, a target relative humidity Rhs having a value smaller than the current relative humidity and closest to the current target relative humidity is selected from the plurality of target relative humidities Rhs to be 55%, and then 55% is used as the first target environmental parameter, that is, the finally required target relative humidity Rhs. It is understood that a SET sensible temperature SET^*The s may correspond to a plurality of target environment parameters, but values of the plurality of target environment parameters may be different, so that energy consumption required for respectively adjusting the detected current environment parameter value to the values of the plurality of target parameters is also different. It can be understood that the smaller the difference between the values of the plurality of target environmental parameters and the current environmental parameter is, the smaller the energy consumption required for adjusting the current environmental parameter to the target environmental parameter is, so that a person with a value equal to the current environmental parameter in the plurality of target environmental parameters is taken as the first target parameter, or when the difference is not equal, a person with a value smaller than the current environmental parameter and closest to the current environmental parameter in the plurality of target environmental parameters is taken as the first target parameter, and the energy consumption can be reduced to the greatest extent while the somatosensory temperature is set, that is, the most energy is saved. Therefore, the embodiment of the invention selects the one with the value equal to or less than the current environmental parameter and closest to the value of the current environmental parameter as the first target environmental parameter, so that the sensible temperature is set, the operation energy consumption of the air conditioner is saved to the greatest extent, and the air conditioner is more energy-saving.

In some embodiments, among a plurality of enthalpy difference values obtained by subtracting the enthalpy values corresponding to the target environmental parameters from the enthalpy value corresponding to the current environmental parameter, the enthalpy difference value corresponding to the first target environmental parameter and the current environmental parameter is the smallest. Specifically, if the current environmental parameter, such as the current relative humidity Rh or the current indoor temperature Ta, has a corresponding enthalpy value in the air psychrometric chart, and similarly, if the plurality of target environmental parameters also have corresponding enthalpy values in the air psychrometric chart, the enthalpy values corresponding to the plurality of target environmental parameters are respectively different from the enthalpy value corresponding to the current environmental parameter, so as to obtain a plurality of enthalpy value difference values, and the plurality of target environmental parameters include the first target environmental parameterMarking environmental parameters, because the SET body sensing temperature SET^*If yes, the current environmental parameter is adjusted to the minimum energy consumption of the first target environmental parameter, correspondingly, the enthalpy difference value between the first target environmental parameter and the current environmental parameter is the minimum, namely, the first target environmental parameter and the current environmental parameter are the closest to each other in the air enthalpy-humidity diagram, and therefore, the first target environmental parameter is adopted to save the energy consumption the most during adjustment.

It is understood that in the air psychrometric chart, the same SET sensible temperature SET^*Generally, the sensible temperatures corresponding to a plurality of state points are equal, and the coordinate of each state point corresponds to a data SET consisting of a target indoor temperature Ts and a target relative humidity Rhs, so that the sensible temperature SET is SET to be the same in the air psychrometric chart^*The corresponding plurality of state points in _, can be embodied as a plurality of data sets consisting of the target indoor temperature Ts and the target relative humidity Rhs distributed in the air psychrometric chart. The coordinates of the points corresponding to the currently detected indoor temperature Ta and the currently detected relative humidity Rh are also embodied as a set of data sets, so that in the air psychrometric chart, the target relative humidity Rhs or the target indoor temperature Ts corresponding to the point closest to the point among the plurality of state points is the first target environmental parameter, and the difference between the corresponding enthalpy value and the enthalpy value corresponding to the currently detected indoor temperature Ta and the relative humidity Rh is the minimum, so that when the currently detected indoor temperature Ta and the currently detected relative humidity Rh are adjusted to the target indoor temperature Ts or the target relative humidity Rhs, the required energy consumption is the lowest, namely, the energy is saved the most.

For example, as shown in figure 2, a schematic diagram of an air psychrometric chart according to one embodiment of the present invention is shown. As can be seen from fig. 2, the current indoor temperature Ta is 29 ℃ and the relative humidity Rh is 90%, which corresponds to the state point a; if the sensible temperature SET is SET^*26.0 ℃, and the corresponding multiple state points in the air psychrometric chart are respectively: a B-state point where the target indoor temperature Ts is 25.4 ℃ and the target relative humidity Rhs is 65%, a C-state point where the target indoor temperature Ts is 25.8 ℃ and the target relative humidity Rhs is 55%, and a D-state point where the target indoor temperature Ts is 26 ℃ and the target relative humidity Rhs is 45%, and the A-state point, the B-state point, the C-B-state point, the C-B-C-state-C-state point, the C-state point, and the C-state point, the C-state-C-state-C,The four state points of the D state points have different corresponding enthalpy values in the air psychrometric chart and are respectively arranged on the corresponding isenthalpic lines, wherein the isenthalpic lines indicate that the corresponding enthalpy values of each state point on the lines are the same. Wherein, the enthalpy value corresponding to the state point A is ha, the enthalpy value corresponding to the state point B is hb, the enthalpy value corresponding to the state point C is hc, and the enthalpy value corresponding to the state point D is hd, and as can be seen from figure 2, the enthalpy values corresponding to the four state points are ha > hb > hc > hd. Therefore, the enthalpy difference value required for adjusting the relative humidity from the state A point to the state B point is ha-hb; adjusting the relative humidity from the A state point to the C state point, wherein the enthalpy difference value is ha-hc; the enthalpy difference value needed for adjusting the relative humidity from the state point A to the state point D is ha-hd, and the enthalpy difference value between the state point A and each of the other state points indicates that (ha-hb) < (ha-hc) < (ha-hd), so that the current relative humidity or indoor temperature is adjusted from the state point A to the target relative humidity Rhs or the target indoor temperature Ts corresponding to the state point B, and the energy is saved. And the standard effective temperature SET corresponding to the B state point, the C state point and the D state point^*Same, therefore, the standard effective temperature SET^*In the following, the comfort feeling of the user is the same, but the power consumption required by the air conditioner is different, so that the point B closest to the point A is selected, and the energy consumption can be saved to the maximum extent. Therefore, the minimum enthalpy difference value between the target environmental parameters and the current environmental parameter is selected as the first target environmental parameter, and the energy consumption of the air conditioner can be saved to the maximum extent on the premise of meeting the comfort experience of a user.

In some embodiments, the temperature SET is sensed according to a SET body-sensing temperature^*S and the first target environmental parameter, determining a second target environmental parameter, comprising: will SET the body-sensing temperature SET^*And s and the first target environment parameter are input into a preset somatosensory temperature-first target environment parameter-second target environment parameter functional relation to obtain a second target environment parameter. The determination of the second target environmental parameter, i.e., the target indoor temperature Ts, will be described by taking the first target environmental parameter as the target relative humidity Rhs as an example. Specifically, the sensible temperature SET is SET^*There is a functional correspondence between s, target relative humidity Rhs and target indoor temperature TsRelationships, e.g. SET^*F (Ts, Rhs), it can be seen that the body-sensing temperature SET will be SET^*S and the target relative humidity Rhs are substituted into the functional relation, and the target indoor temperature Ts is obtained by calculation. For example, the body-sensing temperature SET will be SET^*The equation for the function is substituted with 26 ℃ and 65% of the target relative humidity Rhs, and the target indoor temperature Ts is 25.4 ℃, that is, 25.4 ℃.

In some embodiments, the temperature SET is sensed according to a SET body-sensing temperature^*S and the first target environmental parameter, determining a second target environmental parameter, comprising: and obtaining the second target environment parameter by inquiring a preset mapping table of corresponding relations of the somatosensory temperature, the first target environment parameter and the second target environment parameter, wherein the mapping table of corresponding relations of the somatosensory temperature, the first target environment parameter and the second target environment parameter comprises a plurality of groups of corresponding relations of the somatosensory temperature, the first target environment parameter and the second target environment parameter. It is understood that the temperature SET is SET to the body-sensing temperature SET^*And s, the first target environment parameter and the second target environment parameter have a corresponding relation, any two parameters are determined, and the other parameter can be obtained by table look-up. Of course, in the embodiment, when determining the two parameters, the two parameters may also be determined by the SET^*Another parameter is calculated as a function of f (Ta, Rh). The preset mapping table of the correspondence relationship between the sensible temperature, the first target environment parameter and the second target environment parameter is obtained by calibrating a large amount of test data, for example, according to a SET^*And f (Ta, Rh) function decoupling is carried out to obtain a large amount of corresponding relation data between the somatosensory temperature, the first target environment parameter and the second target environment parameter, and then a preset somatosensory temperature, the first target environment parameter and the second target environment parameter corresponding relation mapping table is obtained through calibration.

Hereinafter, the first target environmental parameter is taken as the target relative humidity Rhs as an example, and the SET sensible temperature SET is determined^*S and the target relative humidity Rhs, the determination of the second target environmental parameter, i.e., the target indoor temperature Ts, will be described.

From the correspondence table, it is known that the SET sensible temperature SET is^*S and the first target environment parameter, calculating according to a look-up table or function to obtain a second target environment parameter, such as SET somatosensory temperature SET^*Determining a target indoor temperature Ts of 25.4 ℃ through a lookup table 2, wherein s is 26 ℃ and the target relative humidity Rhs is 65 ℃; also for example, SET^*The target indoor temperature Ts is determined to be 25.8 ℃ by looking up table 2, with s being 26 ℃ and the target relative humidity Rhs being 55%.

In other embodiments of the present invention, as shown in table 5, the SET sensible temperature SET is a specific embodiment of the present invention^*And s, a mapping table of the corresponding relation between the target relative humidity and the target indoor 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 SET sensible temperature SET _ s value, such as 27 ℃, is input, data as shown in table 5 are automatically generated, and one group of data in the table is the target relative humidity Rhs and the target indoor temperature Ts. In Table 5, n is 1,2, …, and m is 0,1,2 …. Due to the problem of the value precision of B, a plurality of target relative humidity values may actually correspond to 1 target indoor temperature value together.

For example, as shown in table 6, the sensible temperature SET is SET^*S is 27 ℃, and when the precision of B is 0.5 ℃, A is increased by 5 percent, for example, when the relative humidity Rh is 50 percent, the corresponding indoor temperature Ta is 27.0 ℃; when the relative humidity Rh is 55%, the corresponding indoor temperature Ta is 26.8 ℃; when the relative humidity Rh is 60%, the corresponding indoor temperature Ta is 26.6 ℃, 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 ℃.

In some embodiments, the environmental parameter is relative humidity Rh, the corresponding first target environmental parameter is target relative humidity Rhs, and the corresponding second target environmental parameter is target indoor temperature Ts; alternatively, the environmental parameter is the indoor temperature Ta, the corresponding first target environmental parameter is the target indoor temperature Ts, and the corresponding second target environmental parameter is the target relative humidity Rhs. It can be understood that the first target environment parameter and the second target environment parameter are determined by determining the current environment parameter, and the air conditioner is controlled to operate according to the first target environment parameter and the second target environment parameter, so that the indoor comfort level can be accurately adjusted, the comfort level feeling of a user is improved, and the requirement of a human body on the comfort level is met.

In some embodiments, the control method of the air conditioner further includes: determining the actual sensible temperature according to the current relative humidity Rh and the indoor temperature Ta; display module for controlling air conditioner to alternately display actual sensible temperature and SET sensible temperature SET^*S. It can be understood that the air conditioner senses the temperature SET according to the SET body^*When the air conditioner runs in the air-conditioning system, the indoor temperature Ta and the relative humidity Rh can be continuously changed along with the running refrigeration or dehumidification of the air conditioner, so that the relative humidity Rh and the indoor temperature Ta need to be detected in real time, and the relative humidity Rh and the indoor temperature Ta are brought into SET^*F (Ta, Rh), and thus, the actual body-sensory temperature is determined. And, a display module for controlling the air conditioner, e.g. air conditioner display screenAlternative display of actual sensible temperature and SET sensible temperature SET^*S, thereby providing convenience for the user to know the current actual body sensing temperature and the SET body sensing temperature SET in time^*S, is convenient for feeling the temperature SET to the SET body according to the requirement^*And (4) timely regulating and controlling the _.

In some embodiments, in step S1, the SET sensible temperature SET of the air conditioner is obtained^*S and current environmental parameters, comprising: periodically acquiring SET somatosensory temperature SET of air conditioner at intervals of preset time^*S and the current environmental parameters. For example, every five minutes, the SET sensible temperature SET is acquired again^*S and relative humidity Rh, and SET sensible temperature SET according to the relative humidity Rh^*Re-determining the target relative humidity Rhs and the target indoor temperature Ts, and periodically and dynamically determining a new target relative humidity Rhs and a new target indoor temperature Ts when the indoor temperature Ta and the relative humidity Rh change, namely periodically and dynamically optimizing the optimal target relative humidity Rhs and the target indoor temperature Ts, so as to ensure that the air conditioner can SET the sensible temperature SET^*S operation, thereby meeting the requirement of users on comfort and saving energy consumption to the maximum extent.

A control device of an air conditioner according to an embodiment of the second aspect of the present invention will be described with reference to fig. 3.

Fig. 3 is a block diagram of a control apparatus of an air conditioner according to an embodiment of the present invention. As shown in fig. 3, the control device 2 of the air conditioner according to the embodiment of the present invention includes an acquisition module 20, a first determination module 21, a second determination module 22, and a control module 23. The acquiring module 20 is configured to acquire a set sensible temperature of the air conditioner and a current environmental parameter, where the environmental parameter includes an indoor temperature or a relative humidity; the first determining module 21 is configured to determine a first target environmental parameter according to the set somatosensory temperature and the current environmental parameter; the second determining module 22 is configured to determine a second target environmental parameter according to the set somatosensory temperature and the first target environmental parameter; the control module 23 is configured to control the operation of the air conditioner according to the first target environmental parameter and the second target environmental parameter.

According to the control device 2 of the air conditioner, the SET sensible temperature SET is acquired^*S and current environmental parameters, such as indoor temperature Ta or relative humidity Rh, to determine a first target environmental parameter, SET, based on a SET sensible temperature^*Determining a second target environment parameter by the _Sand the first target environment parameter, and controlling the operation of the air conditioner by taking the first target environment parameter and the second target environment parameter as control parameters to realize the common control of the indoor temperature Ta and the relative humidity Rh, so that the air conditioner can sense the temperature SET according to the SET somatosensory temperature^*The indoor comfort level is accurately adjusted by the aid of the s, the situation that the temperature is singly taken as a control target is avoided, when the indoor temperature Ta is appropriate, the real comfort level of a user is poor in feeling due to the fact that the relative humidity Rh is higher or lower is solved, accordingly, the comfort level of the indoor environment is improved, and the comfort experience of the user is improved.

In some embodiments, the first determination module 21 is specifically configured to obtain a temperature corresponding to a SET body-sensory temperature SET^*A plurality of target environmental parameters of _; and taking the one with the value equal to the environmental parameter or smaller than the current environmental parameter and closest to the value of the current environmental parameter as the first target environmental parameter.

It can be understood that the same sensible temperature may correspond to a plurality of different air temperatures Ta and phasesFor the humidity Rh, in other words, a plurality of different SETs of air temperature Ta and relative humidity Rh, which finally correspond to the standard effective temperature SET^*May be the same. For example, SET the standard effective temperature SET^*The air temperature Ta and the relative humidity Rh can correspond to 26.0 ℃, respectively, to 25.4 ℃ and 65%, respectively, or to 25.8 ℃ and 55%, respectively, 26.2 ℃ and 45%. Thereby, the SET sensible temperature SET is determined^*S, then the SET sensible temperature SET corresponding to the SET sensible temperature can be obtained^*S, such as a plurality of target relative humidities Rhs or a plurality of target indoor temperatures Ts. Further, the temperature SET can be sensed from the SET body temperature SET^*S corresponds to the first target parameter determined to be ultimately required, i.e., the ultimately required target relative humidity Rhs or the target indoor temperature Ts, among the plurality of target environmental parameters.

Setting sensible temperature SET by taking environmental parameters as relative humidity for illustration^*When the temperature is 26 ℃, acquiring and setting body sensing temperature SET^*A plurality of target relative humidities Rhs corresponding to 26 ℃. Wherein each SET body sensing temperature SET^*S corresponds to a plurality of target relative humidities Rhs, e.g. SET body temperature SET^*SET sensible temperature SET at 26 deg.C^*The target relative humidity Rhs for 26 ℃ may be 35%, 65%, 55%, etc. Air conditioner for setting body sensing temperature SET^*During operation at 26 ℃, if the current relative humidity is detected to be 35%, the current relative humidity is 35% or more, for example, 35%, 65%, and 55% of the determined target relative humidity Rhs, then the current relative humidity is equal to the current relative humidity, and then the current relative humidity is Rhs% or moreSelecting the one with the same value as the current relative humidity as a first target environment parameter, namely the first target environment parameter is 35%; if it is detected that the current relative humidity is 82%, because there is no one with the same relative humidity as the current relative humidity among the determined values of the target relative humidities Rhs, selecting 65% which is the closest to the current relative humidity and is smaller than the current relative humidity from the target relative humidities Rhs as a first target environmental parameter, that is, the value of the first target environmental parameter is 65%, that is, the finally required target relative humidity Rhs; for another example, when the current relative humidity is detected to be 59%, a target relative humidity Rhs having a value smaller than the current relative humidity and closest to the current target relative humidity is selected from the plurality of target relative humidities Rhs to be 55%, and then 55% is used as the first target environmental parameter, that is, the finally required target relative humidity Rhs. It is understood that a SET sensible temperature SET^*The s may correspond to a plurality of target environment parameters, but values of the plurality of target environment parameters may be different, so that energy consumption required for respectively adjusting the detected current environment parameter value to the values of the plurality of target parameters is also different. It can be understood that the smaller the difference between the values of the plurality of target environmental parameters and the current environmental parameter is, the smaller the energy consumption required for adjusting the current environmental parameter to the target environmental parameter is, so that a person with a value equal to the current environmental parameter in the plurality of target environmental parameters is taken as the first target parameter, or when the difference is not equal, a person with a value smaller than the current environmental parameter and closest to the current environmental parameter in the plurality of target environmental parameters is taken as the first target parameter, and the energy consumption can be reduced to the greatest extent while the somatosensory temperature is set, that is, the most energy is saved. Therefore, the embodiment of the invention selects the one with the value equal to or less than the current environmental parameter and closest to the value of the current environmental parameter as the first target environmental parameter, so that the sensible temperature is set, the operation energy consumption of the air conditioner is saved to the greatest extent, and the air conditioner is more energy-saving.

In some embodiments, the enthalpy values corresponding to the plurality of target environmental parameters respectively correspond to the enthalpy values corresponding to the current environmental parametersAnd in the plurality of enthalpy difference values obtained by difference, the enthalpy difference value corresponding to the first target environment parameter and the current environment parameter is the minimum. Specifically, if the current environmental parameter, such as the current relative humidity Rh or the current indoor temperature Ta, has a corresponding enthalpy value in the air psychrometric chart, and similarly, if the plurality of target environmental parameters have corresponding enthalpy values in the air psychrometric chart, the enthalpy values corresponding to the plurality of target environmental parameters are respectively different from the enthalpy value corresponding to the current environmental parameter to obtain a plurality of enthalpy value difference values, and the plurality of target environmental parameters include the first target environmental parameter because of the sensible temperature SET at the SET sensible temperature^*If yes, the current environmental parameter is adjusted to the minimum energy consumption of the first target environmental parameter, correspondingly, the enthalpy difference value between the first target environmental parameter and the current environmental parameter is the minimum, namely, the first target environmental parameter and the current environmental parameter are the closest to each other in the air enthalpy-humidity diagram, and therefore, the first target environmental parameter is adopted to save the energy consumption the most during adjustment.

For example, referring to FIG. 2, the current indoor temperature Ta is 29 deg.C and the relative humidity Rh is90%, i.e., corresponding to the a state point; if the sensible temperature SET is SET^*26.0 ℃, and the corresponding multiple state points in the air psychrometric chart are respectively: the enthalpy of the four state points of the A state point, the B state point, the C state point and the D state point in the air enthalpy-humidity diagram is different from that of the four state points of the target indoor temperature Ts of 25.4 ℃, the target relative humidity Rhs of 65%, the target indoor temperature Ts of 25.8 ℃, the target relative humidity Rhs of 55%, and the target indoor temperature Ts of 26 ℃ and the target relative humidity Rhs of 45%, and the enthalpy of the four state points of the A state point, the enthalpy of the four state points of the B state point, the enthalpy of the four state points of the C state point and the enthalpy of the D state point are respectively on the corresponding isenthalpic lines, wherein the enthalpy of each state point on the isenthalpic line is the same. Wherein, the enthalpy value corresponding to the state point A is ha, the enthalpy value corresponding to the state point B is hb, the enthalpy value corresponding to the state point C is hc, and the enthalpy value corresponding to the state point D is hd, and as can be seen from figure 2, the enthalpy values corresponding to the four state points are ha > hb > hc > hd. Therefore, the enthalpy difference value required for adjusting the relative humidity from the state A point to the state B point is ha-hb; adjusting the relative humidity from the A state point to the C state point, wherein the enthalpy difference value is ha-hc; the enthalpy difference value needed for adjusting the relative humidity from the state point A to the state point D is ha-hd, and the enthalpy difference value between the state point A and each of the other state points indicates that (ha-hb) < (ha-hc) < (ha-hd), so that the current relative humidity or indoor temperature is adjusted from the state point A to the target relative humidity Rhs or the target indoor temperature Ts corresponding to the state point B, and the energy is saved. And the standard effective temperature SET corresponding to the B state point, the C state point and the D state point^*Same, therefore, the standard effective temperature SET^*In the following, the comfort feeling of the user is the same, but the power consumption required by the air conditioner is different, so that the point B closest to the point A is selected, and the energy consumption can be saved to the maximum extent. Therefore, the minimum enthalpy difference value between the target environmental parameters and the current environmental parameter is selected as the first target environmental parameter, and the energy consumption of the air conditioner can be saved to the maximum extent on the premise of meeting the comfort experience of a user.

In some embodiments, the second determining module 22 is specifically configured to input the set sensible temperature and the first target environmental parameter into a preset sensible temperature-first target environmental parameter-second target loopAnd obtaining a second target environment parameter in the environment parameter function relation. The determination of the second target environmental parameter, i.e., the target indoor temperature Ts, will be described by taking the first target environmental parameter as the target relative humidity Rhs as an example. Specifically, the sensible temperature SET is SET^*There is a functional correspondence between s, target relative humidity Rhs and target indoor temperature Ts, e.g. SET^*F (Ts, Rhs), it can be seen that the body-sensing temperature SET will be SET^*S and the target relative humidity Rhs are substituted into the functional relation, and the target indoor temperature Ts is obtained by calculation. For example, the body-sensing temperature SET will be SET^*The equation for the function is substituted with 26 ℃ and 65% of the target relative humidity Rhs, and the target indoor temperature Ts is 25.4 ℃, that is, 25.4 ℃.

In some embodiments, the second determining module 22 is specifically configured to obtain the second target environment parameter by querying a preset mapping table of correspondence relationships between sensible temperatures, the first target environment parameter, and the second target environment parameter, where the mapping table of correspondence relationships between sensible temperatures, the first target environment parameter, and the second target environment parameter includes multiple sets of correspondence relationships between sensible temperatures, the first target environment parameter, and the second target environment parameter. It is understood that the temperature SET is SET to the body-sensing temperature SET^*And s, the first target environment parameter and the second target environment parameter have a corresponding relation, any two parameters are determined, and the other parameter can be obtained by table look-up. Of course, in the embodiment, when determining the two parameters, the two parameters may also be determined by the SET^*Another parameter is calculated as a function of f (Ta, Rh). The preset mapping table of the correspondence relationship between the sensible temperature, the first target environment parameter and the second target environment parameter is obtained by calibrating a large amount of test data, for example, according to a SET^*And f (Ta, Rh) function decoupling is carried out to obtain a large amount of corresponding relation data between the somatosensory temperature, the first target environment parameter and the second target environment parameter, and then a preset somatosensory temperature, the first target environment parameter and the second target environment parameter corresponding relation mapping table is obtained through calibration.

In some embodiments, the control module 23 is further configured to determine the actual sensible temperature according to the current relative humidity Rh and the indoor temperature Ta; display module for controlling air conditioner to alternately display actual sensible temperature and SET sensible temperature SET^*S. It can be understood that the air conditioner senses the temperature SET according to the SET body^*When the air conditioner runs in the air-conditioning system, the indoor temperature Ta and the relative humidity Rh can be continuously changed along with the running refrigeration or dehumidification of the air conditioner, so that the relative humidity Rh and the indoor temperature Ta need to be detected in real time, and the relative humidity Rh and the indoor temperature Ta are brought into SET^*F (Ta, Rh), and thus, the actual body-sensory temperature is determined. And a display module for controlling the air conditioner, e.g. the air conditioner display screen alternately displaying the actual sensible temperature and the SET sensible temperature SET^*S, thereby providing convenience for the user to know the current actual body sensing temperature and the SET body sensing temperature SET in time^*S, is convenient for feeling the temperature SET to the SET body according to the requirement^*And (4) timely regulating and controlling the _.

In some embodiments, the obtaining module 20 is specifically configured to periodically obtain the SET sensible temperature SET of the air conditioner at intervals of a preset time period^*S and the current environmental parameters. For example, every five minutes, the SET sensible temperature SET is acquired again^*S and relative humidity Rh, and SET sensible temperature SET according to the relative humidity Rh^*S re-determining the target relative humidity Rhs and the target indoor temperature Ts, and periodically and dynamically determining the new target relative humidity Rhs and the target indoor temperature Ts when the indoor temperature Ta and the relative humidity Rh change, namely periodically and dynamically optimizingThe optimal target relative humidity Rhs and the target indoor temperature Ts ensure that the air conditioner can SET the sensible temperature SET^*S operation, thereby meeting the requirement of users on comfort and saving energy consumption to the maximum extent.
