Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 shows a flow chart of a starting frequency adjusting method for an air conditioner compressor according to an embodiment of the present invention. Referring to fig. 1, the start frequency adjusting method includes:
s11, acquiring the outdoor environment temperature at the moment of starting the air conditioner, a plurality of outdoor temperature thresholds and working modes preset in the air conditioner, and the real-time running frequency and the target running frequency of the compressor of the air conditioner;
s12, comparing the outdoor environment temperature with the outdoor temperature thresholds to obtain a comparison result, and setting the starting frequency and the rising frequency of the air conditioner compressor according to the comparison result and the working mode;
and S13, adjusting the real-time running frequency of the air conditioner compressor to the starting frequency, and increasing the ascending frequency to the target running frequency on the basis of the real-time running frequency every preset time.
In the embodiment of the invention, the outdoor environment temperature refers to the air temperature of the installation position of the outdoor unit of the air conditioner. The outdoor environment temperature can be acquired in real time through the temperature sensor arranged outdoors or can be acquired in real time through the temperature sensor arranged independently. Those skilled in the art can select a suitable temperature sensor and its installation position according to the specific application, and the invention is not limited.
The working module comprises a cooling mode and a heating mode. Of course, other modes, such as an air blowing mode, etc., may be included, and those skilled in the art should select the mode according to the specific scenario, and the present invention is not limited thereto. The plurality of outdoor temperature thresholds are a plurality of temperature thresholds set according to actual demands, and a plurality of outdoor temperature sections can be formed by using the plurality of outdoor temperature thresholds.
For example, in the cooling mode, the plurality of outdoor temperature thresholds may be set to 3, including the temperature threshold a, the temperature threshold B, and the temperature threshold C, and 4 outdoor temperature intervals may be formed by using the 3 temperature thresholds. For another example, in the heating mode, the plurality of outdoor temperature thresholds may be set to be 3, including the temperature threshold D, the temperature threshold E, and the temperature threshold F, and 4 outdoor temperature intervals may be formed by using the 3 temperature thresholds. Of course, one skilled in the art can determine the required outdoor temperature interval according to a specific scenario, and then determine the number of outdoor temperature thresholds. And, along with the increase of the number of outdoor temperature intervals, the more meticulous the regulation to the air conditioner compressor, the more reliable and/or better cooling and temperature rise effect of working condition that this moment air conditioner has, the more the adjustment result also fits user's actual demand promptly. It can be seen that the technical solutions of the embodiments of the present invention can be implemented no matter how many temperature thresholds are selected by those skilled in the art, and the above solutions also fall into the scope of the present invention.
The real-time operating frequency of the air conditioner compressor is the operating frequency at the current moment when the compressor is to be adjusted. In practical applications, the real-time operating frequency may refer to an operating frequency acquired by the speed sensor in a current acquisition period. Those skilled in the art can select a corresponding speed sensor according to a specific scenario, and adjust the acquisition period of the speed sensor, which is not limited in the present invention.
The target operating frequency refers to an operating frequency of the compressor when the air conditioner reaches a temperature required by a user. Of course, the target operating frequency may be an operating frequency value in a compressor operating frequency curve that has been stored in the air conditioner in advance. The above target operating frequency can be determined by those skilled in the art according to specific scenarios, and the present invention is not limited thereto.
It should be noted that, in step S1 in the embodiment of the present invention, each parameter of the air conditioner and its compressor may be obtained in one acquisition period, or may be obtained in real time when a certain parameter is needed. The embodiment of the present invention is described by taking an example in which all parameters are acquired in one acquisition period. Of course, those skilled in the art can select the method according to specific scenarios, and the invention is not limited.
The comparison result refers to the magnitude relation between the outdoor environment temperature and a plurality of outdoor temperature thresholds, namely which outdoor temperature interval the outdoor environment temperature is in, and then the starting frequency and the rising frequency of the compressor are set according to the outdoor temperature interval.
The preset time refers to the interval between two adjacent change times of the real-time operation frequency of the compressor. For example, the preset time may be 0.01 to 30 seconds. Preferably, the preset time is set to 1 second. Of course, the skilled person can adjust the length of the preset time according to the specific scenario, and the invention is not limited thereto.
The starting frequency refers to the initial working frequency of the compressor of the air conditioner, and the rising frequency refers to the changing frequency of the compressor every preset time. For example, when the real-time operation frequency of the compressor is 30Hz/s and the rising frequency is 2Hz/s, the real-time operation frequency of the compressor is changed to 32Hz/s at the next second.
The embodiment of the invention takes a controller of an air conditioner as an execution main body to describe in detail the starting frequency adjusting method suitable for the compressor of the air conditioner provided by the embodiment of the invention.
The controller obtains the outdoor environment temperature and a plurality of outdoor temperature thresholds at the moment of starting the air conditioner, and then compares the outdoor environment temperature with the plurality of outdoor temperature thresholds to obtain the relation between the outdoor environment temperature and the outdoor temperature thresholds, namely the comparison result.
And the controller acquires the working mode of the air conditioner and the real-time running frequency of the compressor and then sets the starting frequency and the rising frequency of the compressor of the air conditioner according to the comparison result and the working mode.
In practical application, the air conditioner has the conditions of severe environment, large load or small load and good environment (not severe) in the use environment, and the embodiment of the invention sets different starting frequencies and rising frequencies for the compressor according to different use conditions and working modes.
In an embodiment of the present invention, in the cooling mode, step S2 includes:
s21, when the outdoor environment temperature is larger than a temperature threshold value C, setting the starting frequency and the rising frequency of the air conditioner compressor according to a first outdoor load algorithm;
and S22, when the outdoor environment temperature is less than or equal to the temperature threshold value C, setting the starting frequency and the rising frequency of the air conditioner compressor according to a second outdoor load algorithm.
In the embodiment of the present invention, the temperature threshold C may be set to 30 degrees celsius, and the temperature threshold C may be used to distinguish whether the air conditioner is used in an environment. In the cooling mode, when the outdoor environment exceeds 30 degrees celsius, the use environment of the air conditioner is relatively harsh, and the load of the air conditioner is large, so as to ensure reliable operation of the air conditioner, as shown in fig. 2, the first outdoor load algorithm in step S21 in the embodiment of the present invention includes:
s211, when the outdoor environment temperature is greater than a temperature threshold A, setting the starting frequency of the compressor of the air conditioner to be a frequency N1, and setting the rising frequency of the compressor of the air conditioner to be a frequency M1;
s212, when the outdoor environment temperature is greater than a temperature threshold B and less than or equal to the temperature threshold A, setting the starting frequency of the air conditioner compressor to be a frequency N2, and setting the rising frequency of the air conditioner compressor to be a frequency M2;
and S213, when the outdoor environment temperature is greater than the temperature threshold C and less than or equal to the temperature threshold B, setting the starting frequency of the air conditioner compressor to be frequency N3, and setting the rising frequency of the air conditioner compressor to be frequency M3.
The temperature threshold value a, the temperature threshold value B, and the temperature threshold value C decrease in this order. In practical application, the temperature threshold a is 46 ℃, the temperature threshold B is 38 ℃ and the temperature threshold C is 30 ℃. Of course, the skilled person can select the specific data of the above temperature thresholds A, B and C according to the specific use case, and the invention is not limited thereto.
The frequency N1, the frequency N2, and the frequency N3 may be set to the same frequency value, or may be increased in order. In an embodiment of the invention, the values of the frequency N1, the frequency N2, and the frequency N3 range from 15 to 25 Hz. The person skilled in the art can set the frequency N1, the frequency N2 and the frequency N3 according to a specific scenario, and the present invention is not limited thereto.
The values of the frequency M1, the frequency M2, and the frequency M3 increase in order. For example, the value range of the frequency M1 can be 1-2 Hz/s; the value range of the frequency M2 can be 2-3 Hz/s; the value range of the frequency M3 can be 3-4 Hz/s. The skilled person can set M1, M2 and M3 according to specific scenarios, and the present invention is not limited.
When the outdoor environment is less than 30 ℃, the service environment of the air conditioner is better, and the load of the air conditioner is smaller, at this time, the air conditioner can reliably work, and in order to further improve the efficiency of the air conditioner, the second outdoor load algorithm in step S22 in the embodiment of the present invention includes:
when the outdoor environment temperature is less than or equal to the temperature threshold C, setting the starting frequency of the air conditioner compressor to be a frequency N4, and setting the rising frequency to be a frequency M4.
The frequency N4 can be 40-50 Hz, and the frequency M4 can be 1-3 Hz/s.
For example, in the cooling mode, the starting frequency and the rising frequency of the air conditioner compressor are respectively as follows:
(1) when the outdoor environment temperature T > a (a ═ 46 ℃, the compressor is started at a low frequency, i.e., frequency N1, at this time, the frequency N1 may be 15 to 25Hz, and the rising frequency may be 1 to 2 Hz/s.
(2) Outdoor ambient temperature in the interval: when B is less than or equal to the value A (B is 38 ℃), the compressor is started at a low frequency, namely the frequency N2, at the moment, the frequency N2 can be 15-25 Hz, and the rising frequency can be 2-3 Hz/s;
(3) outdoor ambient temperature in the interval: when C is less than or equal to the value B (C is 30 ℃), the compressor is started at a low frequency, namely the frequency N3, at the moment, the frequency N3 can be 15-25 Hz, and the rising frequency can be 3-4 Hz/s;
(4) when the outdoor environment temperature T is less than or equal to C, the compressor is directly started at high frequency, namely frequency N4, at the moment, the frequency N4 can be 40-50 Hz, and the rising frequency can be 1-3 Hz/s.
In another embodiment of the present invention, in the heating mode, step S2 includes:
s21', when the outdoor environment temperature is larger than a temperature threshold value F, setting the starting frequency and the rising frequency of the air conditioner compressor according to a third outdoor load algorithm;
s22', when the outdoor environment temperature is less than or equal to the temperature threshold value F, the starting frequency and the rising frequency of the air conditioner compressor are set according to a fourth outdoor load algorithm.
In the embodiment of the invention, the temperature threshold F can be set to-15 ℃, and the temperature threshold F can be used for distinguishing the quality of the use environment of the air conditioner. In the heating mode, when the outdoor environment exceeds-15 ℃, the use environment of the air conditioner is relatively harsh, and the load of the air conditioner is relatively large, so as to ensure reliable operation of the air conditioner, as shown in fig. 3, the third outdoor load algorithm in step S21' in the embodiment of the present invention includes:
s211', when the outdoor environment temperature is greater than the temperature threshold D, setting the starting frequency of the compressor of the air conditioner to be a frequency N5, and setting the rising frequency of the compressor of the air conditioner to be a frequency M5;

and S213, when the outdoor environment temperature is greater than a temperature threshold F and less than or equal to the temperature threshold E, setting the starting frequency of the air conditioner compressor to be a frequency N7, and setting the rising frequency of the air conditioner compressor to be a frequency M7.
The temperature threshold D, the temperature threshold E, and the temperature threshold F decrease in this order. In practical application, the temperature threshold D is 15 ℃, the temperature threshold E is-2 ℃, and the temperature threshold C is-15 ℃. Of course, the skilled person can select the specific data of the above temperature thresholds D, E and F according to the specific use case, and the invention is not limited thereto.
The frequency N5, the frequency N6, and the frequency N7 may be set to the same frequency value, or may be increased in order. In an embodiment of the invention, the frequency N5, the frequency N6, and the frequency N7 range from 20 to 30 Hz. The person skilled in the art can set the frequency N5, the frequency N6 and the frequency N7 according to a specific scenario, and the present invention is not limited thereto.
The values of the frequency M5, the frequency M6, and the frequency M7 increase in order. For example, the value range of the frequency M5 can be 1-2 Hz/s; the value range of the frequency M6 can be 2-3 Hz/s; the value range of the frequency M7 can be 3-4 Hz/s. The skilled person can set M5, M6 and M7 according to specific scenarios, and the present invention is not limited.
When the outdoor environment is less than-15 ℃, the service environment of the air conditioner is better, and the load of the air conditioner is smaller, at this time, the air conditioner can reliably work, and in order to further improve the efficiency of the air conditioner, the fourth outdoor load algorithm in step S22' in the embodiment of the present invention includes:
when the outdoor environment temperature is less than or equal to the temperature threshold F, setting the starting frequency of the air conditioner compressor to be a frequency N8, and setting the rising frequency to be a frequency M8.
The frequency N8 can be 50-60 Hz, and the frequency M8 can be 1-3 Hz/s.
For example, in the heating mode, the starting frequency and the rising frequency of the air conditioner compressor are respectively as follows:
(1) when the outdoor environment temperature T > D (D ═ 15 degrees celsius), the compressor is started at a low frequency, i.e., frequency N5, at this time, the frequency N5 may take a value of 20 to 30Hz, and the rising frequency may take a value of 1 to 2 Hz/s.
(2) Outdoor ambient temperature in the interval: when the E is less than or equal to the D value (the E is minus 2 ℃), the compressor is started at a low frequency, namely the frequency N6, the frequency N6 can be 20-30 Hz, and the rising frequency can be 2-3 Hz/s;
