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.
In the prior art, after the maximum allowable operating parameter (for example, the maximum operating frequency or the maximum rotation speed of the fan or the compressor) of the outdoor unit (for example, the fan or the compressor) of the air conditioner is set, the real-time operating parameter of the outdoor unit of the air conditioner does not exceed the maximum allowable operating parameter no matter the external heat exchange condition. The inventor finds that, usually, the maximum allowable operating parameter set by the external unit of the air conditioner is not the rated maximum operating parameter of the fan, for example, the rated maximum rotating speed of the external fan of the air conditioner is 1500 rpm, and a designer can set the maximum allowable rotating speed of the fan to 1000 rpm according to the energy consumption, heat exchange capacity requirements and other reasons of products, and when the external heat exchange condition is poor, the rotating speed of the external fan needs to be as large as possible to achieve an ideal heat exchange effect, and at this time, the maximum allowable rotating speed limits the heat exchange efficiency of the air conditioner. When the external heat exchange condition is good, the rotating speed of the outer fan does not need to be too large to achieve a good heat exchange effect, and the highest allowable rotating speed is not required to be set, so that the power consumption is high.
Based on the technical problems discovered by the inventor, the embodiment of the present application provides a control method for an air conditioner external unit, the control method is mainly applicable to an external fan or a compressor of an air conditioner, as shown in fig. 1, the control method for the air conditioner external unit includes the following steps:
wherein, first external environment temperature can utilize the temperature acquisition module who sets up at the outer machine of air conditioner, for example: and the temperature sensor acquires the temperature. The first operation power is mainly determined by the capacity requirement of the air conditioning system, the parameter is related to the required refrigerating capacity or heating capacity of the air conditioning system, the parameter directly determines the operation speed of the compressor, and the operation speed of the compressor determines the heat exchange requirement of the system; the preset rated power refers to rated refrigerating capacity or rated heating capacity of the air conditioning system and is determined by a hardware structure of the air conditioner.
In a specific implementation, when it is determined that a trigger condition for adjusting the maximum allowable frequency of the air conditioner external unit is met, adjusting an operation parameter of the air conditioner external unit, for example: the highest operation parameter of the air conditioner outdoor unit can be adjusted at intervals of a preset time period; or when the second external environment temperature of the external environment where the air conditioner is located is judged to be beyond the preset external environment temperature range, adjusting the highest operation parameter of the external unit of the air conditioner; and/or adjusting the highest operation parameter of the air conditioner external unit when the operation capability of the air conditioner is stable within the preset first time period, namely the operation capability of the air conditioner is not fluctuated. The maximum allowable operation parameter may be a maximum allowable rotation speed, a maximum allowable operation frequency, and the like of the external unit (e.g., a fan, a compressor).
When the condition that the highest operation parameter of the air conditioner outdoor unit is adjusted when the second external environment temperature of the external environment where the air conditioner is located is judged to be beyond the preset external environment temperature range is specifically realized, the current operation mode of the air conditioner can be obtained, and the preset external environment temperature range corresponding to the current operation mode is obtained; and when the second external environment temperature is determined to exceed the preset external environment temperature range, adjusting the highest operation parameter of the external unit.
For different operating modes of the air conditioner, for example: a cooling mode or a heating mode, respectively preset the respective modesThe preset ambient temperature range, for example, in the cooling mode, is (T) a ，T b ) When the second external environment temperature is monitored to be within the preset external environment temperature range, the highest allowable operation parameter of the external unit does not need to be adjusted; when the second external environment temperature is detected to exceed the preset external environment temperature range, the highest allowable operation parameter of the external unit needs to be adjusted. Taking the cooling mode as an example, T a Any temperature value between 25 ℃ and 30 ℃ can be chosen, for example: 26 ℃; t is b Any temperature value between 37 ℃ and 42 ℃ can be chosen, for example: at 40 ℃.
When the condition that the highest operation parameter of an air conditioner outdoor unit is adjusted when the operation capacity of the air conditioner is stable within the preset first time span is judged, and in concrete implementation, the second operation power of the air conditioner is monitored within the preset first time span; calculating the ratio of the second operating power to a preset rated power to obtain a second target capacity ratio; if the second target capacity ratio is judged to be within the preset first time period, the second target capacity ratio is larger than the preset target capacity ratio; or, if the second target capacity ratio is less than or equal to the preset target capacity ratio within the preset first time period, the operation capacity of the air conditioner is determined to be stable.
For example, the preset first time duration is set to be S minutes, the second target capacity ratio Wc is monitored all the time within the S minutes, and if Wc is not always smaller than or equal to the preset target capacity ratio Wa or Wc is not always larger than the preset target capacity ratio Wa within the preset first time duration S minutes, it indicates that Wc is continuously bouncing up and down at Wa within the S minutes, which indicates that the current operation capacity of the air conditioner is fluctuating, and the fan frequency is not adjusted. If Wc is always smaller than or equal to the preset target capacity ratio Wa or Wc is always larger than the preset target capacity ratio Wa within the preset first time period S minutes, it indicates that the operation capacity of the current air conditioner is already stable, and at this time, the maximum allowable operation parameter of the external unit may be adjusted. In specific implementation, S can take any value between 0.5 and 3; wa may be set to any value between 30% and 70%, for example: and 55 percent.
In the embodiment of the application, whether the operation capacity of the air conditioner fluctuates or not is continuously monitored within the preset first time period, and the continuous time judgment replaces real-time judgment, so that the problem of fluctuation of the operation parameters of the external unit caused by small fluctuation of the operation capacity can be effectively solved, and the system control is more stable.
In addition, it should be noted that, in the embodiment of the present application, the concept of the target capacity ratio is introduced, and is also applicable to a case of multiple units, and the ratio of the sum of the current first operating power of each unit and the sum of the preset rated power of each unit may be calculated to obtain the target capacity ratio, so that the method provided by the embodiment of the present application is applicable to more units, and the universality of the use of the method is enhanced.
102, acquiring an operation parameter compensation value according to the ratio of the first external environment temperature to the first target capacity;
specifically, acquiring a lower limit and an upper limit of the ambient temperature of the operation of the air conditioner; the temperature range determined by the lower limit and the upper limit of the environment temperature is divided into a plurality of temperature intervals, two capacity ratio intervals, namely a capacity ratio interval larger than a preset capacity ratio interval and a capacity ratio interval smaller than or equal to the preset capacity ratio interval, are divided, and the corresponding relation between the temperature intervals, the capacity ratio intervals and the operation parameter compensation value is established, as shown in table 1. When the first external environment temperature and the first target capacity ratio are obtained, the operation parameter compensation value can be determined by looking up the table 1.
TABLE 1 correspondence between temperature and capacity ratio intervals and operating parameter compensation values
Where Wc represents a first target capacity ratio, wa is a preset target capacity ratio threshold, and is a critical point of the division capacity ratio interval. (T) a ，T b ) Presetting an external environment temperature range for the current working mode, when the first external environment temperature is within the preset external environment temperature range, the operation parameter compensation value is 0, namely, the highest operation parameter does not need to be adjusted, and if the first external environment temperature exceeds the preset external environment temperature range, the first external environment temperature and the highest operation parameter need to be adjustedAnd determining a corresponding operation parameter compensation value according to the first target capacity ratio so as to adjust the highest allowable operation parameter of the outer unit according to the operation parameter compensation value.
In specific implementation, the worse the heat exchange condition is, the larger the selected compensation value is. Taking refrigeration as an example, when the external environment temperature is higher, the compensation value of the operation parameter required by refrigeration is larger. In the cooling mode, the temperature range (T) of the external environment is preset a ，T b ) The higher the temperature, the larger the operating parameter compensation value, and the lower the temperature, the smaller the operating parameter compensation value, which is the dividing line. In the heating mode, the temperature range (T) of the external environment is preset a ，T b ) The higher the temperature, the smaller the operating parameter compensation value, and the lower the temperature, the larger the operating parameter compensation value.
Since the preset rated power is a fixed value under the same unit, the compensation value is finally determined to be the current operation capacity, namely the current operation power. In the same temperature interval, when Wc is greater than Wa, the operation capacity of the current system is larger, the required heat exchange amount is larger, and a larger compensation value needs to be selected; on the contrary, when Wc is less than or equal to Wa, it means that the current operation capacity is not very large, and only the ambient temperature causes the heat exchange effect to be still not ideal, and compensation is required, so that a relatively small compensation value can be selected.
It should be noted that the offset value has a positive value and also has a negative value. The compensation is not only to improve the highest operation parameter of the external unit, and under the condition of better heat exchange environment, such as a refrigeration mode, the external environment temperature is lower than 26 ℃, the highest operation parameter of the external unit can also be reduced through the compensation, so that the energy consumption is saved, namely, the operation power of the unit is reduced by reducing the highest operation parameter of the external fan, and the energy-saving effect is achieved.
In the specific implementation, taking the refrigeration mode as an example, T a Any temperature value between 25 ℃ and 30 ℃ can be chosen, for example: 26 ℃; t is a unit of b Any temperature value between 37 ℃ and 42 ℃ can be chosen, for example: at 40 ℃; wa may be set to any value between 30% and 70%, for example: and 55 percent. In the concrete implementation, due to the difference of hardware circuit, capacity and performance of the air conditioner,T a 、T b and Wa may each be determined experimentally or empirically.
The compensation value of the operation parameter corresponding to each temperature interval in table 1 may be determined according to the margin of the operation parameter of the external machine during product design and development, for example: the rated maximum rotating speed of the air conditioner external fan is 1500 revolutions per minute, and designers can set the maximum allowable rotating speed of the external fan to be 1000 revolutions per minute according to the energy consumption, the heat exchange capacity requirement and other reasons of products, and the allowance is 500 revolutions per minute. The setting of the operation parameter compensation value is determined in the margin range of the operation parameters of the external machine, and the adjusted highest allowable operation parameters do not exceed the rated highest operation parameters of the external machine, so that the operation safety and stability are ensured.
103, obtaining the adjusted highest allowable operation parameter of the outdoor unit according to the sum of the preset highest operation parameter of the outdoor unit and the operation parameter compensation value; and controls the outboard motor based on the highest allowable operating parameter.
During specific implementation, the preset highest operation parameter is initialized, and errors of the highest operation parameter in the repeated use process are prevented. After initialization, adjusting the preset highest operation parameter according to the operation parameter compensation value, wherein the actual highest allowable operation parameter = the preset highest operation parameter + the operation parameter compensation value.
In the embodiment of the application, an operation parameter compensation value is obtained according to the ratio of a first external environment temperature of the outside of the air conditioner to a current first target capacity of the air conditioner; the highest operation parameter is adjusted according to the operation parameter compensation value to obtain the highest allowable operation parameter of the outer unit, namely the embodiment of the application provides a method for controlling the highest allowable operation parameter of the outer unit, so that the heat exchange effect of the air conditioner can be increased to a certain extent under the condition that the heat exchange environment is severe, the highest allowable operation parameter of the outer unit is limited under the condition that the heat exchange environment is good, the energy consumption is reduced, the system capacity is maximized, and the energy-saving effect is achieved to a certain extent.
After the operation parameter compensation value is added and the operation is carried out for a period of time with the highest allowable operation parameter, whether the currently adjusted highest allowable operation parameter is suitable or not can be judged by detecting the system pressure. Specifically, after the monitoring outdoor unit operates for a preset second time according to the highest allowable operation parameter, judging that the system pressure value of the air conditioner is greater than or equal to a preset pressure value; acquiring a maximum operation parameter compensation value in the operation parameter compensation values corresponding to the target temperature interval; calculating the sum of the preset highest operation parameter and the maximum operation parameter compensation value to obtain the latest highest allowable operation parameter; the outer machine is controlled based on the latest highest allowable operating parameter.
The preset second duration may be the same as or different from the preset first duration. The system pressure value of the air conditioner can be monitored by a pressure sensor arranged on a compressor pipeline of the air conditioner.
For ease of understanding, the target temperature interval determined when the highest operating parameter is adjusted is [ T ] for example b ，T b1 ) After compensation, after S minutes of operation with the highest allowable operating parameter, when the system pressure value is monitored to reach the preset pressure value, the temperature range [ T ] from the target temperature range is measured b ，T b1 ) Corresponding operating parameter compensation value Z 1 And Z 2 And determining a larger value, and compensating the preset highest operation parameter again to further enhance the heat exchange effect and enhance the reliability of the system.
