Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
For the convenience of understanding the present embodiment, a detailed description will be given below of a method for controlling stress of an air conditioning pipeline according to an embodiment of the present invention.
The embodiment of the invention provides a method for controlling the stress of an air conditioner pipeline, wherein an execution main body is a controller of an air conditioner, and the air conditioner also comprises a compressor connected with the controller; as shown in fig. 1, the method comprises the steps of:
step S102, when a shutdown instruction is monitored, obtaining operation parameters of a compressor;
the operation parameters of the compressor comprise the exhaust pressure value of a refrigerant in the exhaust cavity and the rotation angle of the rotating shaft. As for the compressor, as shown in fig. 2, it mainly includes: the air compressor comprises a cylinder body 2, a slide vane 21, an air suction cavity 22, an air exhaust cavity 23, an air suction port 24, an air exhaust port 25, an air exhaust valve 26, a spring 27, a rotor 28 and a rotating shaft 29; the slide sheet 21 divides the interior of the cylinder body 2 of the compressor into a suction chamber 22 and a discharge chamber 23, when the compressor works, the rotor 28 rotates clockwise around the rotating shaft 29, the volume of the discharge chamber 23 is continuously compressed, and the pressure value of the refrigerant in the discharge chamber 23, namely, a discharge pressure value F is caused Row board Continuously increased, therefore, when the air conditioner is stopped or shut down, the controller is based on the exhaust pressure value F Row board The position of the rotor 28 can be determined to determine if the compressor is immediately shut down.
In addition, when the rotor 28 rotates, the rotation angle a of the rotation shaft is also changed continuously, so that when the air conditioner receives a shutdown command or a shutdown command, the controller can also judge the position of the rotor 28 according to the rotation angle a of the rotation shaft, and judge whether the compressor is stopped immediately.
In summary, when the air conditioner is stopped or shut down, the controller obtains the discharge pressure value F of the refrigerant in the discharge chamber of the compressor Row board And/or the rotation angle A of the rotating shaft and according to the exhaust pressure value F Row board And/or the rotation angle A of the rotating shaft controls whether the compressor is stopped immediately. Wherein, the air conditioner also comprises a collecting device which is in communication connection with the controller, including but not limited to the collecting device for adopting the exhaust pressure value F Row board The first collecting device such as the pressure sensor and the second collecting device such as the angle sensor for collecting the rotation angle a of the rotating shaft, especially, other parameters such as temperature or position information can be collected in part of scenes, and the exhaust pressure value F can be obtained according to other parameters Row board And rotating shaft angle A, e.g. by collecting temperature in the exhaust chamber and calculating exhaust pressure value F according to the temperature Row board Alternatively, a plurality of sensing devices may be provided during rotation of the rotor 28When the rotor 28 reaches the detection device, the corresponding angle information, that is, the rotation angle a of the rotation shaft, is output, and the acquisition of specific control parameters can be set according to actual conditions.
Step S104, judging whether the operation parameters meet the shutdown conditions;
the shutdown condition comprises a preset threshold value and a preset range; the specific judgment process is as follows:
the first mode is as follows: judging the exhaust pressure value F Row board Whether the value is not greater than a preset threshold value F; if not, the operation parameters do not meet the shutdown conditions; specifically, the exhaust pressure value F of the refrigerant in the current exhaust cavity is detected Row board Then, the exhaust pressure value F is judged Row board If the pressure value is less than or equal to F, the current exhaust pressure value of the refrigerant in the exhaust cavity of the compressor is smaller, and the controller can directly control the compressor to stop; if the compressor is controlled to be stopped directly, the compressor vibrates strongly, the stress value of the pipeline is large, and therefore the operation parameters do not meet the stop condition.
Optionally, the method further comprises: acquiring a target exhaust value of a refrigerant in an exhaust cavity in a compressor; and determining a preset threshold value according to the preset multiple and the target exhaust value. Specifically, when the air conditioner is monitored to be started and operated, the compressor is controlled to operate according to a preset frequency; detecting multiple exhaust values corresponding to refrigerant in exhaust cavity during periodic operation of compressor in real time, and taking the maximum exhaust value as target exhaust value, i.e. F = MF Max of row (ii) a For example, after the compressor runs for a week for the first time, a target exhaust value is determined according to a plurality of exhaust values corresponding to the refrigerant in the exhaust cavity in the week so as to obtain a preset threshold value, and the preset threshold value is used for judging whether the compressor is directly stopped or not when the air conditioner is stopped or shut down in a later period. Here the target exhaust value F Max row The threshold value of the exhaust valve 26 is set when the exhaust pressure value of the exhaust chamber reaches F Max row At this time, the discharge valve 26 is opened to cause the refrigerant to be discharged through the discharge port 25, thereby causing the discharge pressure value F to be increased by a predetermined multiple M Row board Does not reach F Max row The preset multiple M is in a range of 0 to 1, preferably 0.6, and specifically can be set to zeroThe setting is carried out according to the actual situation.
It should be noted that, when the preset frequency of the compressor is changed, at this time, the compressor is controlled to operate according to the changed frequency, and in an operation period, a plurality of exhaust values corresponding to refrigerants in an exhaust cavity in the compressor are re-detected, and the maximum exhaust value is used as a target exhaust value corresponding to the changed frequency; and calculating to obtain an updated preset threshold value according to the preset multiple and the target exhaust value corresponding to the change frequency, and judging whether the compressor is stopped immediately or not according to the acquired exhaust pressure value of the refrigerant in the exhaust cavity and the updated preset threshold value when the air conditioner is stopped or shut down.
In addition, except for the preset frequency of the compressor, when the working condition of the compressor changes, the controller updates the preset threshold again, which may specifically refer to the above change frequency, and the embodiments of the present invention are not described in detail herein. And the preset threshold value is adjusted adaptively, so that the accuracy of judging whether the compressor is directly stopped when the air conditioner is shut down or stopped is improved, and the situation that the stress value of the pipeline is large is avoided, the service life of the air conditioner pipeline is prolonged, and the service life of the air conditioner is prolonged.
The second mode is as follows: judging whether the rotating angle A of the rotating shaft meets a preset range or not; the preset range comprises a first rotation angle threshold value A1 and a second rotation angle threshold value A2, and the first rotation angle threshold value A1 is smaller than the second rotation angle threshold value A2; if so, the operating parameter does not satisfy the shutdown condition. Specifically, it is determined whether: the rotating angle A1 of the rotating shaft is more than or equal to A and less than or equal to A2, if the rotating angle A1 of the rotating shaft is more than or equal to A, the current exhaust pressure value of a refrigerant in an exhaust cavity in the compressor is larger, and if the compressor is controlled to be directly stopped, the compressor vibrates strongly, the stress value of a pipeline is larger, so that the operation parameters do not meet the stop condition; otherwise, if the pressure value of the refrigerant in the exhaust cavity in the compressor is not smaller, the controller can directly control the compressor to stop.
The first rotation angle threshold value A1 and the second rotation angle threshold value A2 may be determined according to historical experimental data, and preferably, the first rotation angle threshold value is 150 degrees, the second rotation angle threshold value is 250 degrees, namely when the rotation angle a of the rotating shaft is in the range of 150 degrees to 250 degrees, at this time,the pressure of the gas in the cylinder on the compressor side, i.e., the discharge pressure value, is high (at this time, the discharge pressure value approaches or reaches F) Max row ) If the compressor is stopped at the moment, the rotating shaft rotates reversely violently, so that the compressor vibrates violently; when the rotating angle A of the rotating shaft does not meet the preset range, such as when the rotating angle A of the rotating shaft is within the range of 250-360 degrees, most of refrigerant is discharged out of the cylinder at the moment, and if the compressor is stopped at the moment, the rotating shaft is relatively weak in reverse rotation and relatively weak in vibration; when the rotating shaft angle A is in the range of 0-150 degrees, air suction is performed at the moment, the pressure of a refrigerant is not very high, and if the compressor stops, the rotating shaft is relatively weak in reverse rotation and relatively weak in vibration, so that whether the compressor stops immediately can be judged according to the rotating shaft angle A.
It should be noted that, in the determination process, only the first manner or only the second manner may be adopted, and in some scenarios, the first manner and the second manner may also be adopted at the same time, which may be specifically set according to actual situations.
And step S106, if not, controlling the compressor to continuously operate until the operation parameters meet the stop conditions.
Specifically, when the air conditioner is shut down or stopped, if the control parameter does not satisfy the stop condition, such as the exhaust pressure value F Row board If the detected control parameter is larger than the preset threshold value F or the rotating shaft rotating angle A meets the preset range, the controller controls the compressor to continue to operate until the detected control parameter meets the stop condition, and the compressor is controlled to stop; if the control parameter satisfies a shutdown condition, such as the exhaust pressure value F Row board If the temperature is not greater than the preset threshold value F or the rotating shaft rotating angle A does not meet the preset range, the controller controls the compressor to directly stop running, so that the problem of large stress value of the pipeline is avoided, and the service life of the air conditioner pipeline is prolonged.
According to the method for controlling the stress of the air conditioner pipeline, provided by the embodiment of the invention, when the air conditioner receives a shutdown instruction, the controller judges whether the compressor is shut down immediately or not by detecting the operation parameters of the compressor and according to the operation parameters and the shutdown conditions, so that the problem of large pipeline stress caused by vibration of the compressor during shutdown is solved, the strong vibration of the compressor is avoided, and the service life of the air conditioner pipeline is further prolonged.
For ease of understanding, the exhaust pressure value is used as an example for illustration. As shown in fig. 3, the method comprises the following steps:
step S302, the air conditioner receives a stop signal;
step S304, detecting the pressure of the refrigerant in the current exhaust cavity, namely the exhaust pressure value F Row board And a maximum discharge pressure value F during the entire compression cycle Max of row (ii) a Wherein, the maximum exhaust pressure value F Max of row The method can be determined according to the previous cycle, and also can be determined according to a plurality of exhaust values of the cycle in which the compressor operates for the first time under the current working condition;
step S306, judging F Row board ≤MF Max of row (ii) a If yes, executing step S310, if no, executing step S308; wherein, the value range of M is 0-1, preferably 0.6;
step S308, controlling the compressor to continue to operate until F Row board ≤MF Max row ；
And step S310, controlling the compressor to be directly stopped.
To sum up, according to the method for controlling the pipeline stress of the air conditioner provided by the embodiment of the invention, when the air conditioner receives the shutdown instruction, the exhaust pressure value F in the cylinder body of the compressor is detected Row board To the maximum exhaust pressure F Max of row And comparing F Row board And MF (MF) Max of row Whether the compressor is stopped immediately is judged according to the size of the air conditioner, so that the problem that pipeline stress is large due to vibration of the compressor when the air conditioner is stopped is avoided, the problem that the pipeline stress is large is relieved, the consistency of the pipeline stress is realized, and the service life of an air conditioner pipeline is prolonged.
