And the scenes when the actual consumers use the air conditioner are complex and various, and are easily influenced by comprehensive factors such as the area, the height, the orientation, the building envelope and the like, so that the power of the air conditioner is possibly not matched with the actual requirement.
Therefore, it is an urgent need to solve the problem of how to automatically adjust the cooling and heating capacity of the air conditioner according to the size of the used area.
Disclosure of Invention
The invention solves the problem that the existing air conditioner can not automatically adjust the cold and heat quantity of the air conditioner according to the use area.
In order to solve the above problems, the present invention provides a method for controlling an air conditioner, comprising:
after the air conditioner is powered on, reading preset parameters in an operation mode according to the operation mode of the air conditioner;
acquiring a test time period in the running mode and indoor temperature variation in the test time period according to the preset parameters;
and adjusting the refrigerating capacity or the heating capacity of the air conditioner according to the indoor temperature variation.
Like this, through reading the indoor temperature variation in the test period under the different mode of operation, thereby adjust the refrigerating output or the heating capacity of air conditioner through this indoor temperature variation, and then make the refrigerating output or the heating capacity of air conditioner and the size phase-match in usage space, improve user's travelling comfort. The phenomenon that the air conditioner is shut down when the air conditioner with small power is used in a large room and the refrigerating capacity or the heating capacity in the using space cannot meet the requirement or the air conditioner with large power is used in a small room and the air conditioner is easy to frequently reach a temperature point is avoided, so that the adaptability of the air conditioner and the using space is enhanced.
Optionally, the obtaining, according to the preset parameter, the test period in the operation mode and the indoor temperature variation in the test period includes:
taking a preset time period in the preset parameters as the test time period;
according to the test time period, acquiring the indoor temperature at the starting moment of the test time period and the indoor temperature at the ending moment of the test time period;
and determining the indoor temperature variation according to the indoor temperature at the starting time of the test time interval and the indoor temperature at the ending time of the test time interval.
Like this, through the indoor temperature who obtains test period initial time with the indoor temperature of test period terminal time confirms indoor temperature variation, be favorable to the regulation of the refrigerating output or the heating capacity of air conditioner, and then make the refrigerating output or the heating capacity of air conditioner and the size phase-match of usage space, improve user's travelling comfort.
Optionally, the indoor temperature variation is a temperature difference between the indoor temperature at the starting time of the test period and the indoor temperature at the ending time of the test period.
Therefore, the indoor temperature variation quantity is obtained through the temperature difference between the indoor temperature at the starting time of the test time interval and the indoor temperature at the end time of the test time interval, so that the calculation is convenient, the regulation of the refrigerating capacity or the heating capacity of the air conditioner is facilitated, the refrigerating capacity or the heating capacity of the air conditioner is matched with the size of a use space, and the comfort of a user is improved.

Therefore, the common mode of the air conditioner is a cooling mode or a heating mode, and the refrigerating capacity or the heating capacity of the air conditioner can be adjusted conveniently by acquiring the preset parameters in the cooling mode or the heating mode. Due to the mode in which the ventilation mode or the dehumidification mode is not frequently performed, when the operation mode is the ventilation mode or the dehumidification mode, the control is ended to reduce the loss of energy.
Optionally, the starting time of the test period in the heating mode is greater than or equal to the starting time of the test period in the cooling mode.
Therefore, if the starting time of the test time period in the cooling mode and the starting time of the test time period in the heating mode are the same, the starting time of the test time period in different modes is set to be the same relative to the temperature amplitude change in the cooling mode in the heating mode, so that the indoor temperature variation measured in the heating mode is inaccurate, and the adjustment of the heating quantity is not facilitated. Therefore, the starting time of the test time interval in the refrigeration mode is set to be larger than the starting time of the test time interval in the refrigeration mode, interference caused by the same time is eliminated, and the indoor temperature variation result obtained through calculation is accurate.

and when the indoor temperature variation is greater than or equal to the second temperature threshold, executing second control operation to reduce the refrigerating capacity or the heating capacity of the air conditioner.

Detailed Description
When a consumer purchases the air conditioner, a general salesperson asks the consumer to use the area, and recommends the air conditioner with proper cooling/heating according to the area. And the scenes when the actual consumers use the air conditioner are complex and various, and are easily influenced by comprehensive factors such as the area, the height, the orientation, the building envelope and the like, so that the power of the air conditioner is possibly not matched with the actual requirement. For example, when a small room uses an air conditioner with relatively high power, the phenomenon of shutdown at a temperature point is easy to frequently occur; when a large room uses an air conditioner with relatively low power, this may result in insufficient cooling/heating capacity in the room, and poor user experience.
Correspondingly, as shown in fig. 1, it is a block diagram of an exemplary air conditioner system. The air conditioner system comprises an inner heat exchanger 1, an outer heat exchanger 2, a compressor 3, a four-way valve 4 and a throttling device 5, wherein the inner heat exchanger 1, the outer heat exchanger 2, the compressor 3, the four-way valve 4 and the throttling device 5 are connected to form the air conditioner system. The air conditioner system also comprises a pipeline system, an internal electric heater, a temperature sensing device, an internal wind motor, an external motor, a connecting pipe and the like. The compressor is a variable frequency compressor, and the inner electrode and the outer motor are speed-adjustable motors.
In the refrigeration mode, the refrigerant is absorbed and evaporated in the internal heat exchanger 1, then enters the compressor 3 through the BC path of the four-way valve 4, is discharged from the exhaust port F of the compressor after being compressed, enters the external heat exchanger 2 through the AD path of the four-way valve 4, releases heat and condenses, and then returns to the external heat exchanger 2 after being throttled by the throttling device 5.
In the heating mode, the refrigerant is absorbed and evaporated in the outer machine heat exchanger 2, then enters the compressor 3 through the DC path of the four-way valve 4, is discharged from the exhaust port F of the compressor 3 after being compressed, enters the inner machine heat exchanger 1 through the AB path of the four-way valve 4, releases heat and condenses, and then returns to the outer machine heat exchanger 2 after being throttled by the throttling device 5.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Fig. 2 is a flowchart illustrating a control method of an air conditioner according to an embodiment of the present invention. The embodiment of the invention discloses a control method of an air conditioner, which comprises the following steps:
and S100, after the air conditioner is powered on, reading preset parameters in an operation mode according to the operation mode of the air conditioner.
Wherein, the air conditioner is powered on, which means that the air conditioner is started. The read preset parameters are different according to different operation modes.
And S200, acquiring a test time period in the running mode and indoor temperature variation in the test time period according to the preset parameters.
The test time periods in different operation modes are different, taking the operation modes as a cooling mode and a heating mode as an example, and the test time period in the cooling mode is the time period of the Xth minute and the Xth-Nth minute after the air conditioner is started; and the time period in the heating mode is, for example, the time period from the Y-th minute to the Y-N-th minute after the air conditioner is turned on. After the testing time period is determined in different modes, the temperature variation in the time period is tested.
And S300, adjusting the refrigerating capacity or the heating capacity of the air conditioner according to the indoor temperature variation.
The cooling capacity or the heating capacity of the air conditioner is different from the cooling power or the heating power of the existing air conditioner. Taking the refrigeration power as an example, the conventional refrigeration power refers to the sum of the heat removed from the enclosed space, room or area in a unit time when the refrigeration mode is operated, and is equivalent to the current refrigeration efficiency. The refrigerating capacity of the air conditioner is the upper limit of the refrigerating capacity and the total refrigerating capacity of the air conditioner.
The upper limit of the refrigerating capacity is realized by manually adjusting parameters such as the upper limit of the frequency of the compressor. Taking the example that the upper limit of the cooling capacity is adjusted by the upper limit of the frequency of the compressor, generally, when each hardware device of the air conditioner leaves a factory, the physical upper limit corresponding to each hardware device is already set. In practical application, in order to ensure that each component of the air conditioner can work normally, the upper limit value of each hardware device generally does not reach the physical upper limit, and the working upper limit of each hardware component needs to be limited in a certain limited range so as to ensure that the air conditioner can work stably. For example, in the case of a compressor, the physical upper limit of the frequency of the compressor is set to 100HZ at the time of factory shipment, and when the compressor is operated in cooperation with other components of the air conditioner, the frequency of the compressor can only reach 60HZ at the maximum in order to ensure stable operation of the air conditioner. Here, the compressor frequency of 100HZ means an upper physical limit set at the factory, and the compressor frequency of 60HZ means an upper frequency limit that can be reached by the compressor frequency in order to allow the air conditioner to operate stably. In the present application, the compressor frequency upper limit refers to a temporary upper limit of the compressor frequency readjusted by a manual operation within a frequency upper limit range that the compressor frequency can reach. Also taking the above compressor frequency as an example, for example, in the present application, the temporary upper limit of the compressor frequency is adjusted, the temporary upper limit of the compressor frequency is set to 50HZ, and since the temporary upper limit of the compressor frequency is adjusted, the subsequent air conditioner operates at a frequency not exceeding 50HZ during the operation process, which not only can ensure that the air conditioner can stably operate, but also can limit the output power of the air conditioner during the operation by adjusting the temporary upper limit of the compressor frequency, thereby reducing the cooling capacity. The temporary upper limit of the compressor frequency of the present application can be adjusted according to actual needs, and it is only necessary to set the temporary upper limit of the compressor frequency within the range of the upper limit of the frequency that the compressor frequency can reach, for example, the temporary upper limit of the compressor frequency is set to 40HZ, 45HZ, or any other value less than 60 HZ. In particular, the other numerical values such as 100HZ, 60HZ, and 50HZ are only data provided for convenience of example, and are not actual data.
S100, S200, S300, etc. represent corresponding steps 100, 200, 300, and the order of the steps herein is not meant to be a limitation on the order of execution.
Like this, through reading the indoor temperature variation in the test period under the different mode of operation, thereby adjust the refrigerating output or the heating capacity of air conditioner through this indoor temperature variation, and then make the refrigerating output or the heating capacity of air conditioner and the size phase-match in usage space, improve user's travelling comfort. The phenomenon that the air conditioner is shut down when the air conditioner with small power is used in a large room and the refrigerating capacity or the heating capacity in the using space cannot meet the requirement or the air conditioner with large power is used in a small room and the air conditioner is easy to frequently reach a temperature point is avoided, so that the adaptability of the air conditioner and the using space is enhanced.
Fig. 3 is a flowchart illustrating a control method of an air conditioner according to another embodiment of the present invention. Specifically, the S200: acquiring the test time period in the running mode and the indoor temperature variation in the test time period according to the preset parameters, wherein the method comprises the following steps:
and S210, taking a preset time period in the preset parameters as the test time period.
Wherein the preset time periods are different in different operation modes. In practical application, different preset time periods can be set according to different practical scenes. Specifically, the preset period includes a start time and an end time. In different operation modes, the starting time of the preset time period is different, and the ending time of the preset time period is also different. For example, in the cooling mode, the start point time may be set short according to the attribute unique to the cooling mode. Similarly, in the heating mode, the start time is set longer than the start time in the cooling mode according to the attribute unique to the heating mode.
S220, according to the test time interval, the indoor temperature of the starting moment of the test time interval and the indoor temperature of the ending moment of the test time interval are obtained.
The indoor temperature may refer to an indoor ambient temperature, which is measured using an indoor unit ambient temperature sensor, and mainly detects an ambient temperature in a room. The indoor temperature can also refer to the temperature measured by an indoor unit coil pipe sensor in practical application, and the indoor unit coil pipe sensor is arranged at an air inlet of an indoor evaporator of an air conditioner, is supported by a plastic part and can be used for detecting the indoor side environment temperature. The indoor temperature can also refer to temperature after temperature compensation, and a current temperature compensation value is determined according to the actual indoor environment temperature; based on the temperature compensation value, the detection temperature is corrected, and the comfort of a user is improved. Temperature compensation is used for compensating the temperature in winter and summer in an air conditioner system used in a large building, namely, the set value of the indoor temperature can be changed along with the rise or the fall of the outdoor temperature in summer or winter, so that people feel comfortable. In practical application, the indoor temperature measured under any environment can be selected according to actual conditions.
And S230, determining the indoor temperature variation according to the indoor temperature at the starting time of the test time interval and the indoor temperature at the ending time of the test time interval.
Like this, through the indoor temperature who obtains test period initial time with the indoor temperature of test period terminal time confirms indoor temperature variation, be favorable to the regulation of the refrigerating output or the heating capacity of air conditioner, and then make the refrigerating output or the heating capacity of air conditioner and the size phase-match of usage space, improve user's travelling comfort.
For the calculation of the temperature variation, specifically, the indoor temperature variation is a temperature difference between the indoor temperature at the start time of the test period and the indoor temperature at the end time of the test period.
Therefore, the indoor temperature variation quantity is obtained through the temperature difference between the indoor temperature at the starting time of the test time interval and the indoor temperature at the end time of the test time interval, so that the calculation is convenient, the regulation of the refrigerating capacity or the heating capacity of the air conditioner is facilitated, the refrigerating capacity or the heating capacity of the air conditioner is matched with the size of a use space, and the comfort of a user is improved.
Since the indoor temperature variation is a temperature difference between the indoor temperature at the starting time of the test period and the indoor temperature at the ending time of the test period, and the value of the indoor temperature at the starting time may be greater than or less than the value of the indoor temperature at the ending time in different operation modes, in order to ensure that the obtained indoor temperature variation range is a positive value, an absolute value of the temperature difference is taken during calculation. For example, when the value of the indoor temperature at the start time of the test period is greater than the value of the indoor temperature at the end time of the test period, the indoor temperature variation is obtained by subtracting the indoor temperature at the end time of the test period from the indoor temperature at the start time of the test period. If the value of the indoor temperature at the starting time of the test period is smaller than the value of the indoor temperature at the ending time of the test period, the indoor temperature variation is obtained by subtracting the indoor temperature at the starting time of the test period from the indoor temperature at the starting time of the test period and taking an absolute value of the difference, or the indoor temperature value at the starting time of the test period from the indoor temperature value at the ending time of the test period can be directly used during calculation, so that the value of the obtained indoor temperature variation is ensured to be a positive value.
Fig. 4 is a flowchart illustrating a control method of an air conditioner according to still another embodiment of the present invention. Optionally, in S100, after the air conditioner is powered on, according to the operation mode of the air conditioner, reading the preset parameter in the operation mode includes:
s110, after the air conditioner is powered on, acquiring the running mode of the air conditioner;
the operation mode of the air conditioner includes: a cooling mode, a heating mode, a ventilation mode, and a dehumidification mode.
And S120, reading the preset parameters corresponding to the heating mode or the refrigerating mode when the operation mode is the heating mode or the refrigerating mode.
The preset parameters comprise other parameters such as a preset time interval starting moment, a preset moment ending moment and the like. In the cooling mode and the heating mode, the corresponding preset parameters are different. Specifically, taking preset parameters as a preset time period starting time and a preset time end time as an example, when the operation mode of the air conditioner is a cooling mode, the preset time period starting time and the preset time end time are obtained, and when the operation mode of the air conditioner is a heating mode, the preset time period starting time and the preset time end time different from those in the cooling mode are obtained. The method comprises the steps of presetting a time interval starting moment and a time interval ending moment in a refrigerating mode, and presetting a time interval starting moment and a time interval ending moment in a heating mode.
And S130, when the operation mode is a ventilation mode or a dehumidification mode, ending the control.
When the current operation mode is a ventilation mode or a dehumidification mode, the operation parameters of the air conditioner are not adjusted, and the original operation state is kept.
Therefore, the common mode of the air conditioner is a cooling mode or a heating mode, and the refrigerating capacity or the heating capacity of the air conditioner can be adjusted conveniently by acquiring the preset parameters in the cooling mode or the heating mode. Due to the mode in which the ventilation mode or the dehumidification mode is not frequently performed, when the operation mode is the ventilation mode or the dehumidification mode, the control is ended to reduce the loss of energy.
Optionally, the starting time of the test period in the heating mode is greater than or equal to the starting time of the test period in the cooling mode.
Therefore, if the starting time of the test time period in the cooling mode and the starting time of the test time period in the heating mode are the same, the starting time of the test time period in different modes is set to be the same relative to the temperature amplitude change in the cooling mode in the heating mode, so that the indoor temperature variation measured in the heating mode is inaccurate, and the adjustment of the heating quantity is not facilitated. Therefore, the starting time of the test time interval in the refrigeration mode is set to be larger than the starting time of the test time interval in the refrigeration mode, interference caused by the same time is eliminated, and the indoor temperature variation result obtained through calculation is accurate.
Under the refrigeration mode, the value range of the initial moment of the test time interval is 5-10 min, and because the temperature change amplitude is small under the refrigeration mode, when the temperature is reduced by a few degrees, the temperature which makes a human body feel comfortable can be quickly reached. For example, under the refrigeration condition, when the temperature changes from 35 ℃ to 26 ℃ to 27 ℃, 26 ℃ and 27 ℃ are comfortable temperatures for human bodies, and the temperature changes are only a few degrees apart, so that the temperature difference is small, and the maximum temperature change range can be reached after 5 min. Therefore, in the cooling mode, the time required for the temperature to fall to a temperature at which the temperature change width is relatively large is short. In the heating mode, the value range of the initial time of the test time interval is 10-15 min, and because the temperature change amplitude is relatively large in the heating mode, when the temperature rises to tens of degrees or even twenty degrees, the temperature which makes a human body feel comfortable can be achieved. For example, under the heating condition, the temperature changes from 0 ℃ to 20 ℃, 20 ℃ is a relatively comfortable temperature for human body, and when the temperature changes from 0 ℃ to 20 ℃, the temperature difference is relatively large, so that if the temperature reaches a point with a relatively large temperature change range, the time required is longer than the time required in the cooling mode.
Specifically, when the operation mode of the air conditioner is a refrigeration mode, reading the corresponding test period starting time and test period ending time in the refrigeration mode, wherein the value range of the test period starting time is 5-10 min, and the time interval range of the test period ending time and the test period starting time is 2-3 min. And acquiring the indoor temperature of the starting time of the testing period and the indoor temperature of the ending time of the testing period according to the starting time of the testing period and the ending time of the testing period. And determining the indoor temperature variation according to the indoor temperature at the starting time of the test time interval and the indoor temperature at the ending time of the test time interval. At this time, the indoor temperature variation in the cooling mode is a temperature difference between the indoor temperature at the start time of the test period and the indoor temperature at the end time of the test period.
Similarly, when the operation mode of the air conditioner is a heating mode, reading the corresponding test period starting time and test period ending time in the cooling mode, wherein the value range of the test period starting time is 10-15 min, and the time interval range of the test period ending time and the test period starting time is 2-3 min. And acquiring the indoor temperature of the starting time of the testing period and the indoor temperature of the ending time of the testing period according to the starting time of the testing period and the ending time of the testing period. And determining the indoor temperature variation according to the indoor temperature at the starting time of the test time interval and the indoor temperature at the ending time of the test time interval. At this time, the indoor temperature variation in the heating mode is a temperature difference between the indoor temperature at the start time of the test period and the indoor temperature at the end time of the test period, and an absolute value of the temperature difference is taken. And in the cooling mode and the heating mode, the time intervals of the starting time of the test period and the ending time of the test period are the same.
Fig. 5 is a flowchart illustrating a control method of an air conditioner according to another embodiment of the present invention. Optionally, the S300, adjusting the cooling capacity or the heating capacity of the air conditioner according to the indoor temperature variation includes:
s310, determining a first temperature threshold and a second temperature threshold in the preset parameters under the operation mode, wherein the first temperature threshold is smaller than the second temperature threshold.
The first and second temperature thresholds in the cooling mode are different from the first and second temperature thresholds in the heating mode.
And S320, when the indoor temperature variation is smaller than or equal to the first temperature threshold, executing a first control operation, and increasing the refrigerating capacity or the heating capacity of the air conditioner.
The first control operation is performed when the amount of change in the indoor temperature in the cooling mode is less than or equal to the first temperature threshold in the cooling mode, or when the amount of change in the indoor temperature in the heating mode is less than or equal to the first temperature threshold in the heating mode.
And S330, when the indoor temperature variation is greater than or equal to the second temperature threshold, executing a second control operation, and reducing the refrigerating capacity or the heating capacity of the air conditioner.
The second control operation is performed when the amount of change in the indoor temperature in the cooling mode is greater than or equal to the second temperature threshold in the cooling mode, or when the amount of change in the indoor temperature in the heating mode is greater than or equal to the second temperature threshold in the heating mode.
Thus, when the amount of change in the indoor temperature is different, the control operation performed is different. When the indoor temperature variation is smaller than or equal to a first temperature threshold, executing a first control operation to increase the refrigerating capacity or the heating capacity of the air conditioner; and when the temperature change is larger than or equal to the second temperature threshold value, executing second control operation to reduce the refrigerating capacity or the heating capacity of the air conditioner. Therefore, the air conditioner can control the refrigerating capacity or the heating capacity of the air conditioner according to the indoor temperature variation, and the adaptability of the air conditioner to the use space is enhanced.
Optionally, when the indoor temperature variation is greater than the first temperature threshold and smaller than the second temperature threshold, it is indicated that the usage space of the air conditioner matches the operating power of the air conditioner, at this time, no other control operation is performed on the air conditioner, and the air conditioner continues to operate according to the existing operating state. Therefore, the state when the indoor temperature variation is larger than the first temperature threshold and smaller than the second temperature threshold is used as an intermediate buffer state, so that the air conditioner does not need to continuously increase or decrease the refrigerating capacity or the heating capacity of the air conditioner due to the fluctuation of the actually measured refrigerating capacity or heating capacity.
In the refrigeration mode, the value range of the first temperature threshold is 0-2 ℃, and the value range of the second temperature threshold is 3-5 ℃. Under the heating mode, the value range of the first temperature threshold is 0-3 ℃, and the value range of the second temperature threshold is 6-10 ℃. When the air conditioner is in a refrigeration mode, when the value range of the first temperature threshold is 0-2 ℃, the temperature change of the indoor temperature at the starting time of the test time interval and the temperature change of the indoor temperature at the ending time of the test time interval are not obvious, the refrigerating capacity of the existing air conditioner can be judged to be not up to the requirement of a user, and the refrigerating capacity in a use space needs to be correspondingly increased at the moment so as to improve the comfort level of the user. When the value range of the second temperature threshold is 3-5 ℃, the difference between the indoor temperature at the starting time of the testing period and the indoor temperature at the ending time of the testing period is relatively large, so that the refrigerating capacity of the existing air conditioner is judged to be far beyond the requirement of a user, and the output of the refrigerating capacity needs to be correspondingly reduced at the moment so as to avoid the phenomenon that the air conditioner is stopped when the temperature reaches the point frequently. In the heating mode, when the value range of the first temperature threshold is 0-3 ℃, it is indicated that the temperature change between the indoor temperature at the starting time of the testing period and the indoor temperature at the ending time of the testing period is not obvious, and it can be determined that the heating capacity of the existing air conditioner cannot meet the requirement of a user, and at the moment, the heating capacity in a use space needs to be correspondingly increased so as to improve the comfort level of the user. When the value range of the second temperature threshold is 6-10 ℃, it is indicated that the temperature difference between the indoor temperature at the starting time of the testing period and the indoor temperature at the ending time of the testing period is relatively large, and it can be determined that the heating capacity of the existing air conditioner far exceeds the requirement of a user, and at this time, the output of the heating capacity needs to be correspondingly reduced, so as to avoid the phenomenon that the air conditioner stops when the temperature reaches a temperature point frequently.
Under the refrigeration condition, when the indoor temperature variation is smaller than or equal to the first temperature threshold value, judging that the air conditioner is a low-power air conditioner for a large room, executing a first control operation, and increasing the refrigeration capacity of the air conditioner; when the indoor temperature variation is larger than or equal to the second temperature threshold, executing second control operation, judging that the air conditioner is a large-power air conditioner for a small room, and reducing the refrigerating capacity of the air conditioner; and when the indoor temperature variation is larger than the first temperature threshold and smaller than the second temperature threshold, the room size is adapted to the power of the air conditioner, and at the moment, the operation parameters of the air conditioner are not changed. Similarly, under the heating condition, when the indoor temperature variation is smaller than or equal to the first temperature threshold value different from that in the cooling mode, the air conditioner with low power for the large room is judged, the first control operation is executed, and the heating capacity of the air conditioner is increased; when the indoor temperature variation is larger than or equal to the second temperature threshold value different from that in the refrigeration mode, executing second control operation, judging that the air conditioner is a high-power air conditioner for a small room, and reducing the heating capacity of the air conditioner; and when the indoor temperature variation is larger than the first temperature threshold and smaller than the second temperature threshold, the room size is adapted to the power of the air conditioner, and at the moment, the operation parameters of the air conditioner are not changed.
For the first control operation, optionally, the first control operation comprises: increasing the upper frequency limit of the compressor by a first variable frequency amount; the preset parameter comprises the first frequency conversion quantity. In this way, the upper limit of the frequency of the compressor is increased, so that the refrigerating capacity/heating capacity of the air conditioner is increased, and the target temperature of a user is reached as soon as possible.
Optionally, the first control operation further comprises: increasing a speed of change of the compressor frequency by a first speed change amount; the preset parameter includes the first shift amount. Thus, by increasing the frequency change speed, the refrigerating capacity/heating capacity of the air conditioner is increased, and the target temperature of the user is reached as soon as possible.
Optionally, the first control operation further comprises: increasing the rotating speed of the inner fan or the rotating speed of the outer fan by a second variable; the preset parameter includes the second shift amount. Therefore, the refrigerating capacity/heating capacity of the air conditioner is increased through the rotating speed of the inner fan or the rotating speed of the outer fan, and the target temperature of a user is reached as soon as possible.
For the first control operation, one of the operations may be selected alternatively, for example, by increasing the upper limit of the frequency of the compressor, or increasing the varying speed of the frequency of the compressor, or increasing the rotation speed of the inner fan or the outer fan, thereby increasing the cooling capacity or the heating capacity of the air conditioner. The first control operation may also select two operations to be combined, for example, by increasing the upper frequency limit of the compressor and increasing the frequency variation speed, or by increasing the upper frequency limit of the compressor and increasing the rotation speed of the inner fan or the outer fan, or by increasing the frequency variation speed and increasing the rotation speed of the inner fan or the outer fan, to increase the cooling capacity or the heating capacity of the air conditioner, which is also possible. The first control operation may be a control operation of increasing the upper limit of the frequency of the compressor, increasing the frequency change speed, and increasing the rotation speed of the inner fan or the outer fan, thereby increasing the cooling capacity or the heating capacity of the air conditioner.
It should be noted that, in order to ensure the overall reliability after increasing the upper frequency limit of the compressor, the frequency change speed and the rotating speed of the inner/outer fan, each protection parameter is correspondingly increased; such as current, coil temperature, etc., the down-conversion point is raised accordingly, but the shutdown point should remain unchanged.
Wherein the second control operation comprises: reducing the upper frequency limit of the compressor by a first variable frequency amount; the preset parameter comprises the first frequency conversion quantity. Therefore, the upper limit of the frequency of the compressor is reduced and increased, so that the refrigerating capacity/heating capacity of the air conditioner is reduced, and the air conditioner is prevented from frequently reaching the set temperature and stopping. The second control operation further includes: reducing a variation speed of the compressor frequency by a first variation amount; the preset parameter includes the first shift amount. Therefore, the change speed of the frequency of the compressor is reduced, so that the refrigerating capacity/heating capacity of the air conditioner is increased, and the air conditioner is prevented from frequently reaching the set temperature and stopping. The second control operation further includes: reducing the rotating speed of the inner fan or the rotating speed of the outer fan by a second variable; the preset parameter includes the second shift amount. Therefore, the refrigerating capacity/heating capacity of the air conditioner is reduced through the rotating speed of the inner fan or the rotating speed of the outer fan, and the air conditioner is prevented from frequently reaching the set temperature and stopping.
For the second control operation, one of the operations may be selected alternatively, for example, by lowering the upper limit of the frequency of the compressor, or lowering the frequency change speed, or lowering the rotation speed of the inner fan or the outer fan, thereby reducing the cooling capacity or the heating capacity of the air conditioner. The first control operation may also select two operations to be combined, for example, by lowering the upper frequency limit of the compressor and lowering the frequency variation speed, or by lowering the upper frequency limit of the compressor and lowering the rotation speed of the inner fan or the outer fan, or by lowering the frequency variation speed and lowering the rotation speed of the inner fan or the outer fan, to achieve a reduction in the cooling capacity or the heating capacity of the air conditioner, which is also possible. The first control operation may be to reduce the upper limit of the frequency of the compressor, reduce the variation speed of the frequency of the compressor, and reduce the rotation speed of the inner fan or the outer fan, thereby controlling the operation together, thereby reducing the cooling capacity or the heating capacity of the air conditioner.
The value range of the first variable frequency is 5-10 Hz, the value range of the first variable speed is 0.2-0.5 Hz/S, and the value range of the second variable speed is 30-50 rpm.
Optionally, when the operation of adjusting the cooling capacity or the heating capacity of the air conditioner is performed only once, there may be a case where the cooling capacity or the heating capacity of the air conditioner is not adapted to the actual space used by the air conditioner, so that the adjustment of the cooling capacity or the heating capacity of the air conditioner may be performed in a plurality of cycles until the space used is adjusted to the power of the air conditioner. Taking the cooling mode as an example, when the actual indoor temperature reaches the target temperature, the air conditioner is temporarily stopped. In the short shutdown time, because of the influence of the external environment temperature, the indoor temperature rises, at this moment, the refrigeration mode is restarted, the moment of restarting is the test period starting point moment, after half a minute, the air conditioner resumes the high-speed running state, is the test period end moment this moment, through obtaining the indoor temperature of test period starting point moment and the indoor temperature of test period end moment, calculates the change of temperature, and then the control through the change size of temperature is the increase the refrigerating capacity of air conditioner. And finally, when the remote controller is turned off, acquiring preset parameters again after the remote controller is turned on next time, recalculating the indoor temperature variation, and further adjusting the refrigerating capacity or the heating capacity of the air conditioner.
