In the prior art, when an air conditioner is in refrigeration operation, the outdoor unit cannot radiate heat well due to poor installation in an installation structure of the outdoor unit. However, the compressor in the outdoor unit generally and rapidly increases the set frequency to operate when the air conditioner is started in a refrigerating mode, the set frequency is generally higher, the higher set frequency can increase the starting load of the compressor when the outdoor unit is poorly installed, and the excessive load can cause abnormal shutdown and even burning of the compressor in the starting stage, so that the operation reliability of the air conditioner is affected.
The invention provides the solution, which aims to avoid abnormal operation of the compressor in the refrigeration starting stage of the air conditioner caused by poor installation of the outdoor unit and improve the operation reliability of the air conditioner.

For example, when the outdoor unit 1 is provided with a grill, the temperature detection module 2 may be fixed to the grill.
Further, the outdoor unit 1 further includes a current detection module 3, and the current detection module 3 is specifically configured to detect an operation current of the compressor.
An embodiment of the present invention provides a control device for an air conditioner, and referring to fig. 1, an outdoor unit 1, a temperature detection module 2, and a current detection module 3 are all connected to the control device.

The embodiment of the invention also provides a control method of the air conditioner, which is applied to control the air conditioner. The control method of the air conditioner in the present embodiment is directed to an air conditioner in which the outdoor unit is installed outdoors and a barrier such as an installation structure exists between the outdoor unit and the external environment. For example, an air conditioner in which an outdoor unit is installed in a casing with a grill; or when the mounting cavity is formed on the outer wall of the building, the outdoor unit is arranged in the air conditioner in the mounting cavity.
Referring to fig. 2, an embodiment of a control method of the air conditioner of the present application is provided. In this embodiment, the control method of the air conditioner includes:
step S10, when the air conditioner starts refrigerating operation, controlling a compressor in an outdoor unit to be started at a preset starting frequency, and acquiring installation state information of the outdoor unit; the installation state information is information representing whether the installation position of the outdoor unit is matched with a target position;
the air conditioner cooling operation specifically refers to an air conditioning mode in which the air conditioner is aimed at lowering the indoor ambient temperature. When the air conditioner is in refrigeration operation, the indoor heat exchanger of the air conditioner is an evaporator, and the outdoor heat exchanger in the outdoor unit is a condenser, and in the process, the outdoor heat exchanger is in a heat release state.
In this embodiment, the air conditioner starts the cooling operation, specifically, the air conditioner is powered on from the off state and enters the cooling operation. Based on this, when the air conditioner is powered on, the compressor is powered on and started, and the frequency starts to rise. Specifically, the compressor is run at a rate greater than a preset rate threshold to a preset start-up frequency, and at the same time, the outdoor heat exchanger begins to emit heat. In other embodiments, in this embodiment, the air conditioner starting the cooling operation may also refer to switching the air conditioner from the heating operation to the cooling operation.
Here, the installation state information specifically includes information that the target position of the outdoor unit matches the installation position or information that the target position of the outdoor unit does not match the installation position. The installation state information of the outdoor unit may be obtained by acquiring state information input by a user, or may be obtained by analyzing detection data of a detection module (for example, an image acquisition module, a temperature detection module, etc.) on the outdoor unit or in an environment where the outdoor unit is located.
The preset starting frequency is specifically a preset frequency target value which is required to be reached when the compressor is powered on when the outdoor unit is located at the target position. Further, in this embodiment, in order to ensure that the preset starting frequency is more accurate, different outdoor environment temperatures may be associated with different preset starting frequencies. The higher the preset ambient temperature, the lower the preset start-up frequency. The outdoor environment temperature can be obtained by acquiring data detected by a temperature detection module arranged on an outdoor unit or an installation structure where the outdoor unit is positioned when the air conditioner is not started to perform refrigeration operation, or can be obtained by acquiring weather data of an area where the air conditioner is positioned based on a network. Based on this, before step S10, the outdoor ambient temperature is acquired; acquiring the preset starting frequency according to the outdoor environment temperature; the preset starting frequency is in a decreasing trend along with the increase of the outdoor environment temperature, so that the compressor is guaranteed to be lifted to a stage of running at the preset starting frequency, the starting pressure of the compressor is not too high to cause damage or stop, and the compressor is guaranteed to be reliably started.
Step S20, when the installation state information is that the installation position is not matched with the target position, controlling the compressor to run at a reduced frequency;
the target position is specifically a mounting position of the outdoor unit in the mounting structure, wherein the mounting position is good in heat dissipation and does not cause the stop of the compressor in the starting stage.
The unmatched target position and mounting position indicate that the outdoor unit is poorly installed, and the radiating effect of the outdoor unit in its mounting structure is poor, and the compressor has the risk of shutting down in its starting stage. At this time, the compressor operates at a reduced frequency, thereby reducing the heat dissipation capacity of the outdoor heat exchanger and avoiding shutdown protection of the outdoor unit due to overhigh temperature.
The down-conversion parameter of the compressor can be determined according to actual requirements. The down-conversion parameter may be a down-conversion target value of the compressor, or may be a down-conversion amplitude, a down-conversion rate, or the like of the compressor. Specifically, the operation frequency of the compressor is directly reduced from the preset starting frequency to the frequency-reducing target value for operation, and the frequency-reducing rate in the process of reducing the operation frequency of the compressor to the frequency-reducing target value may be a preset rate greater than or equal to a preset frequency threshold value, or may be a rate determined based on an actual working condition (for example, based on an outdoor environment temperature, a characteristic parameter of an environment temperature change of the outdoor unit, etc.). In addition, the frequency of the compressor can be controlled according to preset frequency-reducing amplitude or frequency-reducing amplitude based on actual working conditions (such as the characteristic parameters based on the outdoor environment temperature, the change of the environment temperature of the outdoor unit, and the like), and the frequency operation after the frequency-reducing amplitude is reduced by the compressor.
Specifically, in this embodiment, in order to ensure that the compressor is not damaged or stopped, the frequency-reducing rate of the compressor in the process of reducing the frequency operation is greater than the preset rate threshold, and the frequency-reducing rate may be greater than the frequency-increasing rate of the compressor in the stage of increasing the frequency to the preset starting frequency, so as to ensure that the frequency of the compressor can be reduced in time, reduce the heat emitted by the outdoor unit rapidly, and avoid damage or stoppage of the compressor caused by poor heat dissipation due to poor mounting position.
Step S30, controlling the compressor to operate at an increased frequency; the frequency raising rate of the frequency raising operation is smaller than the frequency raising rate in the process from the frequency raising to the preset starting frequency when the compressor is started.
Specifically, the rate of the frequency increase during the operation of the compressor may be a fixed rate or a variable rate. For example, the frequency may be increased at a first rate and then at a second rate, the first rate being less than the second rate, and the duration of the frequency increase at the first rate may be greater than the duration of the frequency increase at the second rate. As another example, the third rate, which may be fixed, is up-converted.
The specific value of the frequency raising rate in the process of raising the frequency of the compressor can be not limited in particular, and only needs to ensure that the frequency raising rate is less than the frequency raising rate in the stage of raising the frequency to the preset starting frequency in the process of starting the compressor before. The rate of the boost in the process of increasing the frequency of the compressor can be determined according to the rate of the actual boost in the process of increasing the preset starting frequency when the compressor is started.
The frequency after the compressor is operated at the increased frequency may be a frequency determined according to a preset frequency-increasing amplitude and a current operating frequency of the compressor, or may be a frequency determined based on an actual operating condition of the air conditioner (for example, based on an outdoor environment temperature, a characteristic parameter of an environment temperature change of the outdoor unit, etc.).
According to the control method for the air conditioner, when the air conditioner starts to perform refrigeration operation, the compressor is started at the preset starting frequency, the installation state information of the outdoor unit is obtained, when the installation state information is that the installation position of the outdoor unit is not matched with the target position, the problem of poor installation of the outdoor unit is indicated, at the moment, the compressor does not operate at the preset starting frequency any more, but operates at the rate smaller than the frequency rising rate during starting after the frequency is reduced, the load of the compressor is gradually increased, so that the load of the compressor in the refrigeration starting stage is not excessive even if the problem of poor installation of the outdoor unit exists, the phenomenon that the compressor is stopped or burnt out is effectively avoided, the operation abnormality of the compressor in the refrigeration starting stage of the air conditioner caused by the poor installation of the outdoor unit is avoided, and the operation reliability of the air conditioner is improved.
Further, in this embodiment, after step S10, when the installation status information is that the installation position matches the target position, the compressor may be controlled to maintain the preset starting frequency. When the compressor is operated at the preset starting frequency for a set period of time, the starting stage of the compressor can be considered to be completed, and the compressor can be controlled to be switched to the target frequency operation required by the refrigeration operation.
Further, in this embodiment, in order to ensure that the heat dissipation capacity of the outdoor unit can be rapidly reduced, it is ensured that the temperature of the environment where the frequency outdoor unit is located does not rapidly increase due to the excessively high frequency in the poor installation state, and the step of controlling the compressor to reduce the frequency comprises: and controlling the compressor to be reduced to a second target frequency for operation, wherein the second target frequency is a preset minimum frequency for the air conditioner during refrigeration operation. Based on this, can be when confirming that there is damage or shut down risk in the compressor, through the heat dissipation capacity adjustment of off-premises station to minimum state, ensure that the temperature can not continue to rise sharply, effectively avoid damage or the shut down of compressor, guarantee the reliable operation of air conditioner.
Further, based on the above embodiment, another embodiment of the control method of the air conditioner of the present application is provided. In this embodiment, referring to fig. 3, the step S30 includes:
Step S31, obtaining a first running current of the compressor and/or obtaining a first temperature in an environment where the outdoor unit is located;
the first running current is detected by a current detection module arranged on the compressor. The first temperature is detected by the temperature detection module which is arranged on the outdoor unit (such as a return air inlet of the outdoor unit) or arranged on a mounting structure where the outdoor unit is located. In this embodiment, the first temperature is specifically the dry-bulb temperature detected by the temperature detection module.
In this embodiment, the first operating current and the first temperature are acquired synchronously. In other embodiments, one of the first operating current and the first temperature may also be obtained according to the actual requirement.
Step S32, determining a target rate according to the first running current and/or the first temperature;
in determining the target rate based on the first operating currents, different first operating currents correspond to different target rates. The first corresponding relation between the running current and the up-conversion rate can be preset and can be in the forms of a calculation relation, a mapping relation, an algorithm model and the like. Based on the first correspondence, a target rate corresponding to the present first operating current may be determined.
In determining the target rate based on the first temperatures, the different first temperatures correspond to different target rates. The second corresponding relation between the temperature of the environment where the outdoor unit is located and the frequency-increasing rate can be preset, and can be in the forms of a calculation relation, a mapping relation, an algorithm model and the like. Based on the second correspondence, a target rate corresponding to the current first temperature may be determined.
In determining the target rate based on the first operating current and the first temperature, the different first temperature and the different first operating current correspond to different target rates. The third corresponding relation between the temperature of the environment where the outdoor unit is located and the frequency-increasing rate can be preset, and can be in the forms of a calculation relation, a mapping relation, an algorithm model and the like. Based on the third correspondence, a target rate corresponding to the present first operating current and the first temperature may be determined.
And step S33, controlling the compressor to operate at the target rate increasing frequency.
Because the first running current and/or the first temperature can accurately reflect the risk of shutdown protection of the outdoor unit at the current installation position of the outdoor unit, based on the risk, the target speed determined by combining the first running current and/or the first temperature is used for controlling the frequency rising of the compressor, so that the frequency rising process of the compressor can be adapted to the actual shutdown risk of the outdoor unit, the accuracy of frequency rising operation is ensured, the shutdown protection of the compressor can not occur in the frequency rising process, the burning or shutdown of the compressor is effectively prevented, and the stable and reliable starting operation of the air conditioner is ensured.
Specifically, in this embodiment, in the first correspondence, the target rate tends to decrease with an increase in the first running current. In the second correspondence, the target rate tends to decrease with an increase in the first temperature. In the third correspondence, the target rate is in a decreasing trend with an increase in the first operating current, and the target rate is in a decreasing trend with an increase in the first temperature.
The greater the first running current and/or the greater the first temperature, the greater the risk of compressor shutdown protection, based on which, the target speed is reduced along with the increase of the first running current and/or the target speed is reduced along with the increase of the first temperature, thereby ensuring that the load of the compressor can be gradually increased at a slow enough speed, reducing the heat emitted by the outdoor heat exchanger in unit time, ensuring that the outdoor machine can timely dissipate heat even if being installed poorly, avoiding the compressor shutdown protection or burnout caused by untimely frequency reduction due to the excessively fast rise of the ambient temperature of the outdoor machine, and ensuring that the air conditioner can be started to run stably and reliably.
Further, based on any one of the above embodiments, a further embodiment of a control method of the air conditioner is provided. In this embodiment, referring to fig. 4, the step S30 includes:
Step S301, controlling the compressor to increase to a first target frequency, where the first target frequency is smaller than the preset starting frequency.
The first target frequency is specifically a preset frequency smaller than a preset starting frequency, and may also be a frequency value determined in a frequency range smaller than the preset starting frequency based on an actual operation condition of the air conditioner.
The frequency up rate in the process of the compressor frequency up to the first target frequency may be determined according to the steps S31 to S33 above, or the frequency up may be performed according to a preset frequency up rate, or the frequency up rate may be determined based on other manners to perform frequency up.
In this embodiment, the frequency of the improved compressor is smaller than the preset starting frequency, so that the heat dissipation capacity of the outdoor heat exchanger is not too high in the state of poor installation of the current outdoor unit, and further, the situation that the compressor is stopped or damaged after the frequency is increased is further ensured, and the reliable operation of the air conditioner is ensured.
In other embodiments, the magnitude of the first target frequency relative to the preset starting frequency is not limited, and the first target frequency may be a target frequency value of the air conditioner required to operate during the cooling operation.
Further, in the present embodiment, referring to fig. 4, before step S301, the method further includes:
Step S01, obtaining a second temperature and a third temperature of the environment where the outdoor unit is located; the second temperature is the temperature detected before the air conditioner starts refrigerating operation, and the third temperature is the temperature detected when the operation time of the compressor at the preset starting frequency reaches the preset time;
the second temperature and the third temperature are detected by the temperature detection module which is arranged on the outdoor unit (such as a return air inlet of the outdoor unit) or arranged on a mounting structure where the outdoor unit is located.
Specifically, when the air conditioner is not powered on, the data detected by the temperature detection module can be obtained and stored in the first setting storage area. Based on this, the second temperature here can be obtained by reading the temperature data held therein from the first set storage area. And starting timing when the compressor is lifted from a frequency smaller than the preset starting frequency to the preset starting frequency, and acquiring data detected by the temperature detection module and storing the data in a second set storage area when the timing time length reaches the preset time length. Based on this, the third temperature here can be obtained by reading the temperature data held therein from the second set storage area.
When the timing is started and the time length is longer than or equal to the preset target time length, the compressor finishes the starting stage and switches from the current frequency to the target frequency required by the refrigeration operation. And the preset time period corresponding to the detected third temperature is smaller than the target time period.
Step S02 of determining a first temperature deviation between the second temperature and the third temperature;
the first temperature deviation is specifically an absolute value of a difference between the second temperature and the third temperature.
Step S03, determining a frequency correction value corresponding to the first temperature deviation;
the frequency correction value may be a frequency correction amplitude or a frequency correction coefficient. The different first temperature deviations correspond to different frequency correction values, and the larger the first temperature deviation is, the smaller the first target frequency obtained after the frequency correction value is corrected is.
Step S04, the first target frequency is obtained after the preset starting frequency is corrected according to the frequency correction value.
When the frequency correction value is the frequency correction amplitude, the difference between the preset starting frequency and the frequency correction amplitude can be used as the first target frequency.
When the frequency correction value is a frequency correction coefficient, the product of the preset starting frequency and the frequency correction coefficient can be used as the first target frequency.
In this embodiment, the temperature deviation of the environment where the outdoor unit is located before and after the air conditioner starts the refrigeration operation can accurately reflect the risk of damage or shutdown protection of the compressor, based on this, the result of correcting the preset starting frequency by combining the temperature deviation is used as the target frequency after the frequency of the compressor is increased, which is favorable for further ensuring that the condition that the compressor is not damaged or shutdown protected is not generated, and ensuring the reliable operation of the air conditioner.
Further, based on any one of the above embodiments, a further embodiment of a control method of the air conditioner is provided. In this embodiment, referring to fig. 5, after step S20, the method further includes:
step S201, obtaining the current second running current of the compressor, and obtaining the fourth temperature and the fifth temperature of the environment where the outdoor unit is located; the fourth temperature is the temperature detected before the air conditioner starts refrigeration operation, and the fifth temperature is the temperature detected currently;
the second running current can be obtained by acquiring detection data of a current detection module arranged in the compressor in real time. Specifically, when the air conditioner is not powered on, data detected by the temperature detection module on the outdoor unit or on the installation structure where the outdoor unit is located can be obtained, and the obtained data is stored in the first set storage area. Based on this, the fourth temperature here can be obtained by reading the temperature data held therein from the first set storage area. The fifth temperature can be obtained by acquiring data detected by a temperature detection module on the outdoor unit or a mounting structure where the outdoor unit is located in real time.
Step S202, when the second operation current is smaller than a preset current threshold value and the second temperature deviation is smaller than a first preset deviation threshold value, the step of controlling the compressor to operate at an increased frequency is executed;
Wherein the second temperature deviation is a temperature deviation between the fourth temperature and the fifth temperature.
The preset current threshold is specifically a critical value of the compressor operation current for distinguishing whether the compressor is stably operated. The first preset deviation threshold is specifically a critical value of a temperature difference between an ambient temperature of an outdoor unit where the compressor is stably operated and a temperature difference between the ambient temperature and the temperature before and after the start of the cooling operation.
When the second running current is smaller than the preset current threshold value and the second temperature deviation is smaller than the first preset deviation threshold value, the compressor is in a stable running state, the damage or stop risk is low, and the compressor can be controlled to increase the frequency to run at the moment, so that the output capacity of the compressor is guaranteed to meet the normal refrigeration running requirement. The process of increasing the operating frequency of the compressor may be implemented according to the related steps in the above embodiments, which are not described herein.
When the second running current is larger than a preset current threshold value, or when the second temperature deviation is smaller than a first preset deviation threshold value, the compressor is not stable, the damage or stop risk is high, and at the moment, the compressor can be controlled to maintain the frequency running after the frequency reduction or continue the frequency reduction, so that the compressor is ensured not to be damaged or stopped.
Further, based on any one of the above embodiments, still another embodiment of the control method of the air conditioner of the present application is provided. In this embodiment, referring to fig. 6, the process of acquiring the installation status information of the outdoor unit in step S10 is specifically as follows:
step S11, obtaining a sixth temperature and a seventh temperature of the environment where the outdoor unit is located; the sixth temperature is a temperature detected before the air conditioner starts refrigerating operation, and the seventh temperature is a temperature detected when the operation duration of the compressor running at the preset starting frequency reaches a preset duration;
the sixth temperature and the seventh temperature are specifically detected by the temperature detection module provided on the outdoor unit (such as a return air inlet of the outdoor unit) or provided on a mounting structure where the outdoor unit is located.
Specifically, when the air conditioner is not powered on, the data detected by the temperature detection module can be obtained and stored in the first setting storage area. Based on this, the sixth temperature here can be obtained by reading the temperature data held therein from the first set storage area. And starting timing when the compressor is lifted from a frequency smaller than the preset starting frequency to the preset starting frequency, and acquiring data detected by the temperature detection module and storing the data in a second set storage area when the timing time length reaches the preset time length. Based on this, the seventh temperature here can be obtained by reading the temperature data held therein from the second set storage area. It should be noted that, the preset duration is the same as the preset duration corresponding to the third temperature detection. The second temperature and the sixth temperature refer to the same concept, and the third temperature and the seventh temperature refer to the same concept.
When the timing is started and the time length is longer than or equal to the preset target time length, the compressor finishes the starting stage and switches from the current frequency to the target frequency required by the refrigeration operation. And the preset time period corresponding to the detected seventh temperature is smaller than the target time period.
And step S12, determining the installation state information according to the sixth temperature and the seventh temperature.
The different sixth temperature and the different seventh temperature may correspond to different mounting status information. Specifically, the corresponding relationship between the temperature of the environment in which the outdoor unit is located before the refrigeration operation is started and the temperature of the environment in which the outdoor unit is located and the installation state information when the outdoor unit is operated at the preset starting frequency for the preset duration can be established in advance. The corresponding relationship may be a direct corresponding relationship between the temperature of the environment where the outdoor unit is located before the refrigeration operation is started and the temperature of the environment where the outdoor unit is located when the refrigeration operation is started and the installation state information when the preset starting frequency is used for reaching the preset time, for example, the temperature of the environment where the outdoor unit is located before the refrigeration operation is started may be divided into different first temperature intervals, the temperature of the environment where the outdoor unit is located when the preset starting frequency is used for reaching the preset time is divided into different second temperature intervals, a mapping relationship is established between the different first temperature intervals, the different second temperature intervals and the different installation state information, and the corresponding installation state information can be obtained as the installation state information of the current outdoor unit based on the mapping relationship by determining the first temperature interval where the sixth temperature is located and the second temperature interval where the seventh temperature is located.
In addition, the correspondence may be a correspondence between a temperature relationship parameter and installation state information, where the temperature relationship parameter is determined according to a temperature of an environment where the outdoor unit is located before the refrigeration operation is started and a temperature of the environment where the outdoor unit is located when the outdoor unit is operated at a preset starting frequency for a preset duration, for example, a temperature deviation, a ratio, and the like between the temperature of the environment where the outdoor unit is located before the refrigeration operation is started and the temperature of the environment where the outdoor unit is operated at the preset starting frequency for the preset duration may be used as the temperature relationship parameter, and a mapping relationship between different temperature relationship parameters and different installation state information may be established, based on the temperature relationship parameter, such as a temperature difference or a ratio, between a seventh temperature and a sixth temperature may be determined, so that the corresponding installation state information may be obtained based on the mapping relationship as the installation state information of the current outdoor unit.
Specifically, in this embodiment, step S12 includes: determining a third temperature deviation of the sixth temperature and the seventh temperature; when the third temperature deviation is greater than or equal to a second preset deviation threshold, determining that the installation state information is that the installation position is not matched with the target position; and when the third temperature deviation is smaller than the second preset deviation threshold value, determining that the installation state information is that the installation position is matched with the target position. The second preset deviation threshold is specifically a maximum value allowed by a temperature difference between an environment where the outdoor unit is located before the outdoor unit starts the refrigeration operation when the preset air conditioner is located at the target position and the environment where the outdoor unit is located when the preset air conditioner is operated at the preset starting frequency for a preset duration.
In this embodiment, based on the temperature of the environment where the outdoor unit is located before the air conditioner starts the refrigeration operation and when the air conditioner operates at the preset starting frequency for a preset period of time, the problem that whether the temperature rises too fast exists when the compressor starts at the preset starting frequency corresponding to the target position can be accurately reflected, so that whether the installation position of the outdoor unit is accurately identified based on whether the temperature rises too fast is achieved, the problem that whether the outdoor unit is poor in installation is avoided, the problem that the user operation is avoided, the problem that whether the outdoor unit is poor in installation is accurately identified is solved, the frequency of the compressor in the starting stage can be accurately controlled based on the identification result, the compressor is prevented from being damaged or stopped, and the reliable and stable starting operation of the air conditioner is ensured.
In any of the above embodiments, the temperature of the environment of the outdoor unit is the same as the outdoor environment temperature before the air conditioner is powered on, and the temperature of the environment of the outdoor unit is greater than the outdoor environment temperature after the air conditioner is powered on.
