According to the indoor air quality standard shown in the table 1 in the national standard GB/T18883-2002, the physical relative humidity standard value of the air conditioner is 40-80% when the air conditioner is used in summer.
TABLE 1 indoor air quality Standard
Table 1 Indooor Air Quality Standard
Figure BDA0003433323260000061
According to the recommended value of ISO 7730 in table 2 for the comfort zone, the temperature of the dry bulb is kept between 23 and 26 ℃ during cooling in summer, and the human body feels more comfortable
Table 2: recommended values for the comfort zone in ISO 7730
Figure BDA0003433323260000071
According to the quality standards of indoor air and related research in design parameters, in a normal temperature environment, the relative humidity is in an optimal region (shaded part in fig. 2) of 30% -60%, and in this range, the rate of chemical interaction between bacteria and biological organic tissues is the minimum.
Based on the dry bulb temperature and relative humidity suggestions of the summer refrigeration comfort zone, when the indoor relative humidity is 30-80%, the indoor air quality is better. In practical use, the indoor temperature of the air conditioner is generally higher than the dry bulb temperature of the comfort zone. The drying of the moisture in the air is mainly caused by the generation of condensed water or frost due to the temperature of the air being lower than the dew point temperature. Therefore, to maintain the humidity of the indoor air, it is critical to control the dew point temperature. Table 3 shows the dew point temperature table for different dry bulb temperatures and different relative humidities.

s1, refrigerating operation of an air conditioner;
s2, determining the target humidity H goal Target humidity T goal ；
S3, acquiring the temperature T of the current indoor environment room Humidity H room And inner tube temperature T tube ；
S4, determining the target humidity H goal Target humidity T goal Lower dew point temperature range;
s5, judging the humidity H of the current indoor environment room With a target humidity H goal Comparing, if the current indoor environment humidity H room Lower than or equal to the target humidity H goal According to the temperature T of the inner tube tube Controlling the air conditioner to moisturize the current indoor environment within the dew point temperature range; if the current indoor environment humidity H room Above target humidity H goal According to the indoor ambient temperature T room With a target temperature T goal Temperature difference delta T and indoor environment humidity H room With a target humidity H goal Humidity difference Δ H, inner tube temperature T tube And controlling the air conditioner to dehumidify the current indoor environment by the dew point temperature range.
The air conditioner of the embodiment collects relevant data in real time and carries out measurement on the current indoor humidity H according to the collected data goal And the set target humidity H goal And performing comparison and judgment, dehumidifying when the indoor humidity is higher than the target humidity, and preserving moisture when the indoor humidity is lower than or equal to the target humidity. The data that needs to be collected in the early stage of humidity control in this embodiment includes, but is not limited to, the indoor temperature T room Indoor humidity H goal Inner tube temperature T tube . The parameters to be regulated in the humidity regulation process comprise at least one of the rotating speed of the outer fan, the rotating speed of the inner fan, the frequency F of the compressor and the opening degree of the electronic expansion valve.
The present embodiment determines the current room by setting humidity by designing a control logic for adjusting the humidity of air without adding a humidifying device, by using the characteristic that the air conditioner itself has the capability of reducing the humidity of airWhether dehumidification or moisture preservation is needed in the room, if dehumidification is needed in the room at present, the temperature T of the inner pipe is passed tube Regulating and controlling the operation parameters of the air conditioner to make the temperature T of the inner pipe tube The indoor environment is moisturized within a dew point temperature range under a set temperature and humidity. If dehumidification is needed in the current room, the temperature difference delta T, the humidity difference delta H and the temperature T of the inner pipe are used tube Regulating and controlling the operation parameters of the air conditioner to make the temperature T of the inner pipe tube The lower limit value lower than the dew point temperature range is used for dehumidifying the indoor environment, so that the aim of regulating and controlling the air humidity is fulfilled, and the phenomenon that the air is too dry when an air conditioner operates or the comfort of the indoor environment is influenced due to too high air humidity is avoided.
The target humidity H of the present embodiment, as shown in the control logic diagram of FIG. 3 goal Target humidity T goal The determination of (c) can be implemented in one of three ways:
the first implementation mode comprises the following steps: user-defined target humidity H goal Target humidity T goal (ii) a In one embodiment, the target humidity H is a custom adjustment mode selected when the user needs to adjust the indoor humidity goal Target humidity T goal The value is set for the user.
The second embodiment: setting a target temperature T at a user goal According to the target temperature T goal Matching the theoretically optimal target humidity H in the database goal (ii) a The database of the present embodiment includes an official database and a user database. The method comprises the following specific steps: firstly, judging whether the air conditioner dehumidifies for the first time; if the air conditioner dehumidifies for the first time, according to the target temperature T goal Matching the theoretically optimal target humidity H in the official database goal (ii) a If the air conditioner does not dehumidify for the first time, according to the target temperature T goal Matching the theoretically optimal target humidity H in the user database goal . Specifically, when the user needs to adjust the indoor humidity, an automatic adjustment mode is selected, and if the user has defined the temperature by himself, the first use of the humidity adjustment device matches the theoretically optimal target humidity H according to official data in the database goal The temperature set by the user selects the theoretical optimum at this temperatureHumidity. The temperature and the humidity are two target values which need to be regulated, an official party stores the optimal humidity values at different temperatures in the database in advance, the official party needs to match the theoretically optimal humidity values due to the fact that no user data exist when the air conditioner is used for the first time, and the official party can not match the humidity through the habit of the user, so that the database can be updated after the air conditioner is used for a long time, the optimal matching humidity is closer to the requirement of the user, when the air conditioner acquires enough effective data, the optimal humidity can be matched according to the habit of the user, namely, the optimal humidity is matched through the user database;
the third implementation mode comprises the following steps: when the user does not set the target temperature T goal Automatically selects the optimum target humidity H in the database goal Optimum target humidity T goal Said optimum target humidity H goal Optimum target humidity T goal The temperature and humidity value with the highest frequency of use is selected for the user. The database of the present embodiment includes an official database and a user database. Specifically, whether the air conditioner dehumidifies for the first time is judged; if the user does not have the self-defined temperature, the optimal target temperature T is automatically selected from the database goal And target humidity H goal The optimal temperature and the target humidity which are selected and set through the official database are used for the first time, and if the air conditioner collects enough user data, a group of data [ temperature, humidity and humidity ] with the highest use frequency is selected from the user database]As the target value.
The regulation and control mode of the embodiment designs two regulation modes of the air conditioner humidity, one is automatic regulation, and the other is user-defined regulation; automatic adjustment can set for the best humidity value of current temperature according to the official, or user's use custom and match, and self-defined regulation can set for the humidity value of current demand according to user's demand for humidity control's is convenient. The database of this embodiment divide into official database and user database, and the user uses the custom will be recorded at user database for the air conditioner understands user's custom more, makes the humidity control and the temperature regulation of air conditioner more intelligent. When the user database is not established, the automatic adjustment mode adopts an official database for adjustment; after the user database is established, the user database is establishedThe dynamic adjustment mode will select data in the user database and adjust. When extreme values (i.e. too high or too low temperature, too high or too low humidity) of user data are not recorded in the user database, the temperature and humidity with higher occurrence frequency in the database are more likely to be regarded as H goal 、T goal For automatic adjustment. In order to ensure that more effective data is stored in a limited storage space, the earliest data is removed when the data in the database reaches a set value, and then the database is updated.
Further optionally, if the current indoor ambient humidity H room Lower than or equal to the target humidity H goal Step S5 includes S51 to S52, in which:

In the above embodiment, if the air conditioner does not have an electronic expansion valve, but has a capillary tube, the opening degree of the electronic expansion valve is already determined by the capillary tube and cannot be controlled, and the step of adjusting the opening degree of the electronic expansion valve can be omitted.
In the process, the priority of the protection program in the air conditioner is higher than that of the regulation and control program of each parameter in the embodiment, and when the program regulation and control action or the related parameters exceed the protection range, the protection program is executed to ensure that the air conditioner cannot operate outside the specified range, so that the operation reliability of the air conditioner is ensured.

|ΔT|>T1； (2)
wherein, T1 is an allowable temperature fluctuation boundary value, and the value is positive.
Then according to the temperature difference delta T and the humidity difference delta H (delta H = H) room -H goal ) To determine the compressor frequency F, in a specific embodiment, the compressor frequency F value corresponding to the current humidity difference Δ H and the temperature difference Δ T is solved according to a preset mapping relationship between the temperature difference-humidity difference-compressor frequency, and a simplified formula is as follows:
Figure BDA0003433323260000131
Fmin≤F≤Fmax (4)
and Fmin is the minimum frequency value allowed to operate, and Fmax is the maximum frequency value allowed to operate.
The mapping relation of the temperature difference, the humidity difference and the compressor frequency reflects an adjustment strategy of the compressor frequency, namely, the change of the temperature difference and the humidity difference affects the change of the compressor frequency, and when the temperature difference becomes smaller, the compressor frequency becomes smaller; as the humidity differential becomes larger, the compressor frequency becomes larger until the temperature and humidity differential is maintained near the target range. Setting the model in a controllable range, wherein the larger the Delta T is, the higher the frequency F is; the larger Δ H, the higher the frequency F.
The air conditioner operates at the determined compressor frequency F to dehumidify the indoor environment and also to control the temperature T of the inner pipe tube Monitoring is carried out; and the temperature of the inner pipe is adjusted to T tube Comparing with a dew point temperature range; when the temperature of the inner pipe is T tube When the temperature is lower than or equal to the lower limit value of the dew point temperature range, maintaining the current operation parameters; when the temperature of the inner pipe is T tube When the temperature is higher than the lower limit value of the dew point temperature range, the frequency of the compressor, the opening of the electronic expansion valve, the rotating speed of the outer fan and the rotating speed of the inner fan are respectively corrected according to the set sequence to adjust the temperature T of the inner pipe tube Lower than or equal to the lower limit of the dew point temperature range.
In the process that the air conditioner operates at the determined compressor frequency F to dehumidify the indoor environment, if the temperature T of the inner pipe is at the moment tube If the temperature is lower than the lower limit value of the dew point temperature, the air conditioner continuously generates condensed water at the moment so as to reduce the air humidity, and if the temperature T of the inner pipe is lower than the lower limit value of the dew point temperature at the moment tube If the temperature is higher than the lower limit of the dew point temperature, the frequency of the compressor needs to be corrected, the opening of the electronic expansion valve needs to be adjusted, and the rotating speed of the fan needs to be adjusted (the adjusting mode is opposite to the moisturizing mode) so that T is enabled tube Lower than the lower limit value of the dew point temperature, thereby reducing the air humidity. After maintaining the current frequency for a period of time, the current humidity H is measured again room With a target humidity H goal Making comparison and judgment, if the humidity is at the momentIf the target value is reached, moisturizing; if the target value is still not reached, the dehumidification operation is executed circularly.
(2) The current indoor temperature reaches the target temperature value T goal It is necessary to fluctuate the temperature within a certain range to ensure a more comfortable dehumidification operation. In order to avoid that the indoor temperature is further reduced due to the dehumidification, which affects the customer experience, the temperature difference Δ T is enlarged by introducing a virtual temperature difference M, and then the temperature difference Δ H is increased according to the virtual temperature difference M and the humidity difference Δ H (Δ H = H) room -H goal ) To determine the compressor frequency F, in a specific embodiment, the compressor frequency F value corresponding to the current humidity difference Δ H and the virtual temperature difference M is solved according to a preset mapping relationship between the virtual temperature difference-humidity difference-compressor frequency, and at this time, the compressor frequency is calculated by the following formula:
Figure BDA0003433323260000141
M＝ΔT+C (6)
where M is referred to as the virtual temperature difference; c is called the temperature difference expansion factor and is a constant.
It can be known from the above that the formula (6) is essentially the same as the formula (3), but the addition of the virtual temperature difference M is equivalent to increasing the temperature difference, so that the frequency of the compressor is increased, the cooling capacity is increased at the moment, but the indoor temperature does not change greatly within a certain time.
The air conditioner operates at the determined compressor frequency F to dehumidify the indoor environment and also to control the temperature T of the inner pipe tube Monitoring is carried out; and the temperature of the inner pipe is adjusted to T tube Comparing with a dew point temperature range; when the temperature of the inner pipe is T tube When the temperature is lower than or equal to the lower limit value of the dew point temperature range, maintaining the current operation parameters; when the temperature of the inner pipe is T tube When the temperature is higher than the lower limit value of the dew point temperature range, the frequency of the compressor is corrected to adjust the temperature T of the inner pipe tube Lower than or equal to the lower limit of the dew point temperature range.
In this embodiment, the air conditioner operates at the determined compressor frequency F to dehumidify the indoor environmentIn the process, if the inner tube temperature T tube If the temperature is lower than the lower limit value of the dew point temperature, the air conditioner continuously generates condensed water at the moment, so that the air humidity is reduced, and if the temperature is still not satisfied with T at the moment tube When the temperature is lower than the lower limit value of the dew point temperature, the virtual temperature difference M is required to be increased to realize the correction of the frequency of the compressor, and the temperature difference expansion factor C can be adjusted
The implementation is as follows: c = a C (7)
Wherein alpha is a correction factor, alpha >1, the specific value needs to be further determined according to the allowable compressor frequency fluctuation range and the model performance of the model, and if alpha is larger, the allowable compressor frequency variation range is larger, and the allowable temperature variation range is larger in the dehumidification process.
The frequency of the compressor is adjusted by assigning the product of the correction factor and the temperature difference expansion factor to the temperature difference expansion factor when the temperature T of the inner pipe is within a range tube When the temperature is higher than the lower limit value of the dew point temperature range, the temperature T of the inner pipe is increased after the frequency of the compressor is increased to the highest operation frequency tube When the temperature is still higher than the lower limit value of the dew point temperature range, the opening of the electronic expansion valve, the rotating speed of the outer fan and the rotating speed of the inner fan are respectively corrected according to a set sequence so as to adjust the temperature T of the inner pipe tube Lower than or equal to the lower limit of the dew point temperature range.
In one embodiment, when the frequency is increased to the maximum frequency of the air conditioner, but the inner pipe temperature is still higher than the lower limit value of the dew point temperature range, the opening degree of the electronic expansion valve, the rotating speed of the outer fan and the rotating speed of the inner fan are synchronously adjusted until the inner pipe temperature T is reached tube Within the dew point temperature range.
In another embodiment, when the frequency is increased to the maximum frequency at which the air conditioner can operate, but the temperature of the inner pipe is still higher than the lower limit value of the dew point temperature range, the opening degree of the electronic expansion valve is reduced; when the frequency is increased to the minimum frequency at which the air conditioner can operate, the opening of the electronic expansion valve is reduced to the minimum allowable opening, but the temperature of the inner pipe is still higher than the lower limit value of the dew point temperature range, the rotating speed of the outer fan is increased on the basis of the current rotating speed; when the frequency, the opening of the electronic expansion valve and the rotating speed of the outer fan are all adjusted to be incapable of being adjusted again, but the temperature of the inner pipe is still higher than the lower limit value of the dew point temperature range, the rotating speed of the inner fan is properly reduced on the basis of the current rotating speed, and the inner fan is kept running.
In the above embodiment, if the air conditioner does not have an electronic expansion valve, but has a capillary tube, the opening degree of the electronic expansion valve is already determined by the capillary tube and cannot be controlled, and the step of adjusting the opening degree of the electronic expansion valve can be omitted.
In order to avoid that the indoor temperature is greatly changed due to the change, and the customer experience is influenced. Therefore, when M <0, namely the indoor temperature is lower than the preset allowable fluctuation range, the frequency of the compressor is reduced, the indoor temperature gradually returns to the allowable range, and as the frequency of the compressor is gradually changed, certain condensed water is generated in the process, so that dehumidification is still continued, and the indoor temperature is also changed in a certain range, so that the comfort of a user is ensured.
If the indoor humidity reaches the target humidity, executing a moisturizing command, and if the indoor humidity does not reach the target humidity, continuing to circulate the steps until the humidity reaches the target humidity and entering a moisturizing mode.
The present embodiment also proposes a control device of an air conditioner, which includes one or more processors and a non-transitory computer-readable storage medium storing program instructions, when the one or more processors execute the program instructions, the one or more processors are configured to implement the method of any one of the above.

Although the present invention has been described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the present invention.
