Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. 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 application.
According to an embodiment of the present application, there is provided a control method of an air conditioning apparatus. Alternatively, in the embodiment of the present application, the control method of the air conditioning apparatus described above may be applied to a hardware environment constituted by the terminal 101 and the server 102 as shown in fig. 1. As shown in fig. 1, a server 102 is connected to a terminal 101 through a network, which may be used to provide services (such as video services, application services, etc.) for the terminal or a client installed on the terminal, and a database may be provided on the server or separately from the server for providing data storage services for the server 102, and the network includes but is not limited to: wide area network, metropolitan area network, or local area network, the terminal 101 is not limited to air conditioning equipment, such as: wall-mounted air conditioners, cabinet air conditioners, window air conditioners and ceiling air conditioners.
The control method of the air conditioning equipment according to the embodiment of the present application may be executed by the server 102, by the terminal 101, or by both the server 102 and the terminal 101. Here, the terminal 101 executes the control method of the air conditioning apparatus according to the embodiment of the present application, and may be executed by a client installed thereon.
Taking a terminal as an example to execute the control method of the air conditioning equipment in the embodiment of the present application, the method may be applied to the terminal, fig. 2 is a schematic flowchart of an alternative control method of the air conditioning equipment according to the embodiment of the present application, and as shown in fig. 2, the flowchart of the method may include the following steps:
In some embodiments, the air conditioning unit may be initially operated and then its discharge temperature adjusted by an electronic expansion valve. After the target exhaust temperature is determined, the electronic expansion valve controls the air conditioning equipment according to the target exhaust temperature, so that whether exhaust fluctuation occurs or not can be judged according to the current exhaust temperature of the air conditioning equipment.
The determination of the target exhaust gas temperature may be calculated based on algorithms inside manufacturers of different air-conditioning equipment, and is not limited herein.
In an alternative embodiment, determining that the air conditioning device experiences an exhaust gas surge includes:
acquiring an exhaust temperature value of air conditioning equipment, and recording the exhaust times of which the exhaust temperature value is a target exhaust temperature value; after the exhaust frequency reaches the preset frequency, judging whether the acquired exhaust temperature values are all target exhaust temperature values or not in the process of reaching the target exhaust temperature value for the last N times, wherein N is a positive integer less than or equal to the preset frequency; if not, determining that the air conditioning equipment generates exhaust fluctuation.
In some embodiments, when determining whether the air conditioning equipment has exhaust gas fluctuation, it may be determined by determining whether the exhaust gas temperature of the air conditioning equipment is stable at the target exhaust gas temperature value. Specifically, an exhaust temperature value of the air conditioning equipment is obtained in real time or at preset time intervals, and whether exhaust fluctuation occurs or not is judged according to the exhaust temperature value. Specifically, by recording the number of times of exhaust reaching the target exhaust temperature value, and in the process of reaching the target exhaust temperature value for the last N times, whether the obtained exhaust temperature values are the target exhaust temperature values or not is determined, taking N as 3 as an example, if the exhaust temperature values of three consecutive times are the target exhaust temperature values, it can be considered that the exhaust is stable at this time, otherwise, it is determined that the air conditioning equipment generates exhaust fluctuation.
For example, referring to fig. 3, the flow inflection point of the electronic expansion valve is 385, and the target exhaust temperature value is 62 degrees. During the operation of the air conditioning equipment, the exhaust temperature value is 60-64 ℃, and the opening of the electronic expansion valve is adjusted between 383 and 387, so that exhaust fluctuation is formed. In fig. 3, a thin solid line indicates a change in the exhaust gas temperature value, a broken line indicates an opening degree of the electronic expansion valve, and a thick solid line indicates a target exhaust gas temperature value.
It can be understood that if the air conditioning unit is not fluctuating in the exhaust gas, the air conditioning unit does not need to be adjusted and continues to operate according to the current operating parameters.
In some embodiments, when the air conditioning equipment has exhaust fluctuation, the opening degree of the electronic expansion valve is required to be adjusted to adjust the exhaust temperature of the air conditioning equipment. However, if the opening degree of the electronic expansion valve is at the flow inflection point, the adjustment of the opening degree of the electronic expansion valve may cause an overshoot, resulting in a large change in the exhaust gas temperature, and the air conditioning equipment may still fluctuate in the exhaust gas. Therefore, after the air conditioning equipment generates exhaust fluctuation, whether the opening degree of the electronic expansion valve is within the preset opening degree range of the flow inflection point is judged.
The preset opening range may be set according to actual conditions, and is not limited herein. For example, referring to fig. 4, the flow inflection point of the electronic expansion valve is 385, and the preset opening range may be set to 380 and 390.
In some embodiments, in order to avoid an overshoot condition caused by adjustment of the electronic expansion valve when the opening degree of the electronic expansion valve is within a preset opening degree range of a flow inflection point of the electronic expansion valve, in the present application, the target device parameter of the air conditioning device is adjusted to stabilize the exhaust temperature. The target device parameter may be a device parameter related to the temperature of exhaust gas in the air conditioning device. Since the target plant parameter is related to the exhaust temperature, the exhaust temperature can be changed by adjusting the target plant parameter so as to reach the target exhaust temperature.
The preset opening range of the electronic expansion valve flow inflection point can be confirmed according to the electronic expansion valve flow curve specifically given by manufacturers, and electronic expansion valves of different calibers of different manufacturers have different inflection point parameters. For example, the preset opening range may be set to 380 ± 15, and the electronic expansion valve flow inflection point and the preset opening range may be directly built into the controller of the air conditioning equipment as a basis for determination.
It can be understood that, if exhaust fluctuation occurs during the opening degree adjustment process of the electronic expansion valve, the opening degree adjusted by the electronic expansion valve is only partially within the preset opening degree range, and is also within the preset opening degree range.
It can be understood that, if the opening degree of the electronic expansion valve is not within the preset opening degree range of the flow inflection point of the electronic expansion valve, the opening degree of the electronic expansion valve is adjusted to adjust the exhaust temperature of the air conditioning equipment to reach the target exhaust temperature value.
Specifically, there are various methods for adjusting target equipment parameters of the air conditioning equipment, and the following three cases are specifically described.
In an alternative embodiment, adjusting a target plant parameter of an air conditioning plant comprises:
acquiring the opening range of the electronic expansion valve in the exhaust fluctuation process of the air conditioning equipment, and taking the opening of the electronic expansion valve as a target equipment parameter; and adjusting the opening degree of the electronic expansion valve according to the maximum value and the minimum value in the opening degree range.
In some embodiments, the opening degree of the electronic expansion valve is continuously adjusted during the exhaust gas fluctuation of the air conditioning equipment, and the electronic expansion valve is operated at a fixed opening degree during the exhaust gas fluctuation by acquiring the opening degree range of the electronic expansion valve during the exhaust gas fluctuation of the air conditioning equipment and averaging the maximum value and the minimum value in the opening degree range as the target opening degree of the electronic expansion valve.
Since the exhaust temperature fluctuates around the target exhaust temperature value when the air conditioning equipment exhausts, the finally stabilized exhaust temperature value is also close to the target exhaust, and thus the electronic expansion valve is locked to prevent the circulation capacity fluctuation caused by the over-adjustment of the opening.
In an alternative embodiment, adjusting a target plant parameter of an air conditioning plant comprises:
acquiring current operating parameters of the air conditioning equipment; determining a target operation parameter related to the exhaust temperature in the current operation parameters; and taking the target operation parameter as a target equipment parameter, and adjusting the target operation parameter according to the size relation between the current exhaust temperature value and the target exhaust temperature value of the air conditioning equipment.
In some embodiments, during the operation of the air conditioning equipment, the exhaust temperature is also related to the operation parameters of the air conditioning equipment in addition to the opening degree of the electronic expansion valve, and the current operation parameters are adjusted according to the magnitude relationship between the current exhaust temperature value and the target exhaust temperature value of the air conditioning equipment when the current operation parameters are related to the exhaust temperature value by obtaining the current operation parameters of the air conditioning equipment.
Wherein the current operating parameter may be, but is not limited to, the operating frequency of the air conditioning plant.
In an alternative embodiment, adjusting the target operating parameter based on a magnitude relationship between a current exhaust temperature value and a target exhaust temperature value of the air conditioning unit comprises:
calculating a temperature difference value between the target exhaust temperature value and the current exhaust temperature value; if the temperature difference is larger than or equal to a preset difference, increasing the target operation parameter by a first preset step value; and if the temperature difference is smaller than the preset difference, adjusting the target operation parameter to be smaller than a second preset step value.
And the temperature difference is obtained by subtracting the current exhaust temperature value from the target exhaust temperature value.
In some embodiments, the discharge air temperature is related to an operating parameter of the air conditioning unit in addition to the opening degree of the electronic expansion valve. Generally, the higher the operating frequency of the air conditioning apparatus, the larger the opening degree of the electronic expansion valve. When the operation frequency is a positive correlation parameter of the exhaust temperature, the exhaust temperature is changed by adjusting the current operation frequency, so that the opening degree of the electronic expansion valve is changed, and the inflection point interval is staggered.
The following are exemplary: after the exhaust fluctuation of the air conditioning equipment is determined and the flow inflection point of the electronic expansion valve is determined, the operation frequency can be adjusted properly, for example, the frequency is adjusted to +/-1 HZ, and then the target exhaust gas is recalculated, so that the effect of avoiding the inflection point and stabilizing the operation is achieved. Specifically, whether the frequency increasing or the frequency reducing is controlled when the current operation parameter is related to the exhaust temperature value or not can be judged through the temperature difference between the target exhaust temperature value and the current exhaust temperature value, if the temperature difference between the target exhaust temperature value and the current exhaust temperature value is larger than or equal to 2 degrees, the +1HZ can be adopted, otherwise, the temperature difference between the target exhaust temperature value and the current exhaust temperature value is smaller than 2 degrees, and the processing is carried out according to the-1 HZ.
In an alternative embodiment, adjusting a target plant parameter of an air conditioning plant comprises:
acquiring a target exhaust temperature value; generating a preset temperature interval based on the target exhaust temperature value, wherein the preset temperature interval comprises the target exhaust temperature value;
further, after determining that the air conditioning equipment generates the exhaust fluctuation, the method further comprises the following steps:
judging whether the obtained exhaust temperature values are all in a preset temperature interval in the process of reaching the target exhaust temperature value for M times recently, wherein M is a positive integer less than or equal to the preset times; if not, determining that the air conditioning equipment generates exhaust fluctuation.
In some embodiments, when it is determined that the air conditioning device experiences an exhaust gas fluctuation and the opening degree of the electronic expansion valve is at the flow inflection point thereof, the adjustment of the opening degree of the electronic expansion valve may be avoided by resetting the judgment condition for the exhaust gas fluctuation. Whether the obtained exhaust temperature values are the target exhaust temperature values or not in the process of judging whether the target exhaust temperature values are reached for the last N times of judgment conditions and whether the obtained exhaust temperature values are all in the preset temperature range or not in the process of judging whether the target exhaust temperature values are reached for the last M times of judgment conditions are adjusted, so that when the exhaust temperature slightly fluctuates, the circulation fluctuation of an electronic expansion valve of the air conditioning equipment is not adjusted, namely the exhaust stable direction is widened to correspond to the inflection point adjustment of the electronic expansion valve, and the stable output can be quickly entered.
Where M may be the same as or different from N, for example, M may be, but is not limited to, 3 or 4.
For example, taking the target exhaust temperature as 62 ℃ as an example, the adjustment to 62 ± 2 ℃ or 62 ± 3 ℃ can be determined to satisfy the target exhaust temperature, that is, the final exhaust temperature value falls within 62 ± 2 ℃ or 62 ± 3 ℃ and is identified as reaching the target exhaust temperature.
And step 203, controlling the air conditioning equipment according to the adjusted target equipment parameters so as to stabilize the exhaust temperature value of the air conditioning equipment.
In some embodiments, after determining the adjusted target device parameter, the air conditioning device may be controlled to operate with the adjusted target device parameter, thereby ensuring stability of the air conditioning device.
In the application, exhaust fluctuation occurs in the air conditioning equipment, and the opening degree of the electronic expansion valve is at the flow turning point, so that the condition that the opening degree of the electronic expansion valve is adjusted to avoid overshoot is avoided, the exhaust temperature of the air conditioning equipment is maintained at a target exhaust temperature value by adjusting target equipment parameters related to the exhaust temperature in the air conditioning equipment, the exhaust fluctuation of the air conditioning equipment is avoided, the stability of the outlet air temperature is further kept, and the user experience and the comfort are improved. In the optimization process, the cost is not required to be increased, only logic optimization is required, the problem of hardware defects of the inflection point of the flow of the electronic expansion valve can be solved, fluctuation can be reduced for users through the logic optimization, and the comfort experience of the users is improved.
