The following describes a method, a device and an air conditioning system for controlling the functional compensation of an air conditioner according to the present invention with reference to fig. 1 to 4.
It has been found through studies that the supply voltage of an air conditioner is positively correlated with the performance of the air conditioner, that is, when the supply voltage is lowered, the performance is lowered, and when the supply voltage is raised, the performance is raised accordingly.
In order to facilitate the intuitive description of the positive correlation between the power supply voltage and the functional capability, the following types of air conditioners are used as test objects in the present embodiment, and the parameter comparison map shown in table 1 is obtained through tests.
Model number of air conditioner: AS24PDALAA/1U24 RYCSA; the type of the refrigerant: r32; the model of the compressor: 55X 563H; specification of air conditioner internal unit: 50P; specification of an air conditioner outdoor unit: 3P 12.
Table 1:
as can be seen from table 1, the performance of the air conditioner gradually increases as the supply voltage increases under the same ambient temperature. The environment temperature of the outdoor environment where the air conditioner is located has direct influence on the functional capability of the air conditioner, and under the condition that the power supply voltage is constant, the functional capability of the air conditioner is smaller when the environment temperature is higher, and the functional capability of the air conditioner is in negative correlation with the air outlet temperature of the air conditioner.
Based on the above research, in order to solve or improve the problem that the performance of the conventional air conditioner is low when the air conditioner operates under low voltage and severe environment, the present embodiment provides a performance compensation control method for an air conditioner, in which the air conditioner is connected to the commercial power supply and the ac side of the inverter, respectively, and the dc side of the inverter is connected to the solar power generation device through the switching device.
Thus, in a remote mountain area, when the supply voltage of the air conditioner is unstable, the present embodiment may convert the light energy into the direct current by using the solar power generation device based on the sufficient illumination condition in the remote mountain area, and convert the direct current into the alternating current by using the inverter to supply the alternating current to the air conditioner, thereby ensuring the stable operation of the air conditioner.
As shown in fig. 1, the embodiment provides a method for controlling functional compensation of an air conditioner, where an execution subject of the method may be an air conditioner controller, and may also be a server, and the server is in communication connection with the air conditioner controller, and the method includes the following steps:
and step 110, acquiring the ambient temperature of the outdoor environment where the air conditioner is located and the power supply voltage of the commercial power supply for supplying power to the air conditioner.
And 120, controlling the switching device to be switched on under the condition that the power supply voltage is less than the preset voltage, so that the solar power generation device supplies power to the air conditioner.
And step 130, controlling the output voltage of the inverter according to the threshold range of the environment temperature so as to execute compensation control on the functional capacity of the air conditioner.
Specifically, in this embodiment, based on the corresponding relationship between the power supply voltage and the performance of the air conditioner, by obtaining the ambient temperature of the outdoor environment where the air conditioner is located and the power supply voltage of the commercial power supply for supplying power to the air conditioner, when the power supply voltage of the commercial power is smaller than the preset voltage, the solar power generation device can be immediately utilized to supply power to the air conditioner, and according to the threshold range where the ambient temperature is located, the magnitude of the output voltage of the inverter is selectively controlled, and compensation control over the performance of the air conditioner is executed, so that the machine capability of the air conditioner is improved at the outdoor ambient temperature of low voltage and high temperature, the purpose of regulating and controlling the indoor ambient temperature is achieved, and the user experience is improved.
It should be noted that, in the present embodiment, the ambient temperature of the outdoor environment where the air conditioner is located may be collected by the temperature sensor, and the power supply voltage of the air conditioner may be collected by the voltmeter disposed on the power supply line of the air conditioner. Of course, in this embodiment, the supply current of the air conditioner may be collected by an ammeter disposed on a power supply line of the air conditioner, and then, the supply voltage may be obtained by conversion based on a relationship between the supply current and the supply voltage.
Meanwhile, the preset voltage shown in the present embodiment may be understood as a voltage capable of ensuring the normal operation of the air conditioner. In one embodiment, the predetermined voltage may be an ac voltage having a voltage value of 220V and a frequency of 50 Hz.
In addition, in the present embodiment, the magnitude of the output voltage of the inverter can be controlled by controlling the switching frequency of the relevant power device in the inverter.

Specifically, when the power supply voltage is lower than the preset voltage, the functional capability of the air conditioner is reduced to a certain extent, and when the ambient temperature is higher than or equal to the preset temperature, along with the increase of the ambient temperature, the operation condition of the air conditioner is rapidly deteriorated, so that the functional capability of the air conditioner is further reduced.
In this embodiment, the magnitude of the first voltage output by the inverter may be selectively controlled based on the functional capability corresponding to the current power supply voltage of the air conditioner. For example, when the power supply voltage of the air conditioner is reduced to 150V, the present embodiment may control the output voltage of the inverter to be maintained between 170V and 220V, so as to increase the functional capability of the air conditioner to be below the functional capability under the normal operating condition; the embodiment can also control the output voltage of the inverter to be maintained between 220V and 260V, so that the functional capacity of the air conditioner is greater than that under the normal working condition.

Specifically, when the ambient temperature is lower than the preset temperature, the current capacity of the air conditioner is higher than the capacity corresponding to the preset temperature, so that the output voltage of the inverter is controlled to be equal to the preset voltage.
Here, as the outdoor ambient temperature increases, since the ambient temperature is between 43 ℃ and 48 ℃, the performance of the air conditioner is greatly reduced, and the higher the ambient temperature is, the larger the performance of the air conditioner is reduced, so that the preset temperature is determined to be 43 ℃ to 48 ℃. The preset temperature may be 43 ℃, 45 ℃, 46 ℃, 47 ℃, 48 ℃ and the like, and is not limited herein.

Specifically, because when supply voltage is greater than or equal to preset voltage, the functional power of air conditioner is great to the air conditioner has better refrigeration or heating ability, and this embodiment can be according to every user's demand to ambient temperature, the air-out temperature of quantitatively control air conditioner, in order to reach better experience.
Here, the present embodiment is based on the above control, so that the difference between the air outlet temperature of the air conditioner and the temperature set by the user can be maintained within 1 ℃. The air conditioner can control the outlet air temperature of the air conditioner to reach the first target temperature by adjusting the running frequency of the compressor and/or adjusting the opening of the throttle valve.
Further, when the power supply voltage decreases, in order to prompt an early warning in time, the method shown in this embodiment further includes: and under the condition that the power supply voltage is less than the preset voltage, sending an early warning instruction to the user terminal or the power supply terminal.
Specifically, when the user end is warned, the embodiment can warn the user in any one of the sound-light warning, the voice prompt and the light prompt on site, and can also send the warning information to the mobile phone of the user wirelessly to warn the user remotely.
Meanwhile, when the power supply terminal is pre-warned, the embodiment can send the pre-warning information to the client of the power supply company or the mobile phone of the operation and maintenance personnel in a wired or wireless manner so as to perform remote pre-warning prompt on the power supply terminal.
