Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The following describes a method and a device for controlling capacity compensation of an air conditioner and an air conditioning system according to the present invention with reference to fig. 1 to 4.
It has been found through research that the power supply voltage of an air conditioner is positively correlated with the power capability, that is, when the power supply voltage is reduced, the power capability is reduced, and when the power supply voltage is increased, the power capability is correspondingly increased.
In order to intuitively describe the positive correlation between the power supply voltage and the power, the embodiment uses the following model air conditioner as a test object, and obtains a parameter comparison chart shown in table 1 through a test.
Model number of air conditioner: AS24PDALAA/1U24 RYSCA; refrigerant model: r32; model of compressor: 55X563H; specification of air conditioner indoor unit: 50P; specification of air conditioner external unit: 3P12.
Table 1:
as can be seen from table 1, the capacity of the air conditioner gradually increases with the increase of the power supply voltage at the same ambient temperature. The environmental temperature of the outdoor environment where the air conditioner is located has direct influence on the energy capacity of the air conditioner, under the condition that the power supply voltage is fixed, the energy capacity of the air conditioner is smaller as the environmental temperature is larger, and the energy capacity of the air conditioner is inversely related to the air outlet temperature of the air conditioner.
Based on the above-mentioned research, in order to solve or improve the problem that the capacity of the air conditioner is low when the existing air conditioner works under low voltage and severe environment, the embodiment provides a capacity compensation control method of the air conditioner, the air conditioner is respectively connected with the ac side of the mains supply and the inverter, and the dc side of the inverter is connected with the solar power generation device through the switching device.
Therefore, when the power supply voltage of the air conditioner is unstable in the remote mountain area, the embodiment can utilize the solar power generation device to convert the light energy into the direct current based on the sufficient illumination condition of the remote mountain area, and the inverter converts the direct current into the alternating current so as to supply the alternating current to the air conditioner, thereby ensuring the stable working and running of the air conditioner.
As shown in fig. 1, the present embodiment provides a method for controlling capacity compensation of an air conditioner, where an execution body of the method may be an air conditioner controller or a server, and the server is communicatively connected to the air conditioner controller, and the method includes the following steps:
And step 120, controlling the switching device to be turned on under the condition that the power supply voltage is smaller than the preset voltage, so that the solar power generation device supplies power to the air conditioner.
And 130, controlling the output voltage of the inverter according to the threshold range of the ambient temperature so as to execute compensation control on the capacity of the air conditioner.
Specifically, the embodiment is based on the corresponding relation between the power supply voltage and the power capacity of the air conditioner, and by acquiring the environment temperature of the outdoor environment where the air conditioner is located and the power supply voltage of the mains supply for supplying power to the air conditioner, when the power supply voltage of the mains supply is smaller than the preset voltage, the solar power generation device can be used for supplying power to the air conditioner in real time, the output voltage of the inverter is selectively controlled according to the threshold range where the environment temperature is located, and the compensation control of the power capacity of the air conditioner is performed, so that the power capacity of the air conditioner is improved under the outdoor environment temperature with low voltage and high temperature, the purpose of regulating and controlling the indoor environment temperature is achieved, and the user experience is improved.
It should be noted here that, in this embodiment, the temperature sensor may collect the ambient temperature of the outdoor environment in which the air conditioner is located, and the power supply voltage of the air conditioner may be collected by a voltmeter provided 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 provided on the supply line of the air conditioner, and then the supply voltage may be obtained by conversion based on the relationship between the supply current and the supply voltage.
Meanwhile, the preset voltage shown in the present embodiment can be understood as a voltage that can ensure the normal operation of the air conditioner. In one embodiment, the preset voltage may be an ac voltage with a voltage value of 220V and a frequency of 50 Hz.
In addition, the present embodiment can realize control of the magnitude of the output voltage of the inverter by controlling the switching frequency of the relevant power device in the inverter.
Preferably, the output voltage of the inverter is controlled according to the threshold range where the ambient temperature is, as shown in the present embodiment, to perform compensation control of the capacity of the air conditioner, including, but not limited to, the steps of:
and under the condition that the ambient temperature is greater than or equal to the preset temperature, controlling the output voltage of the inverter to be a first voltage, wherein the first voltage is greater than the power supply voltage and less than the preset voltage, or the first voltage is greater than or equal to the preset voltage.
Specifically, when the power supply voltage is smaller than the preset voltage, the power of the air conditioner can be reduced to a certain extent, and when the ambient temperature is larger than or equal to the preset temperature, the operation condition of the air conditioner can be rapidly deteriorated along with the increase of the ambient temperature, so that the power of the air conditioner is further reduced.
The present embodiment may selectively control the magnitude of the first voltage output by the inverter based on the capability corresponding to the current power supply voltage of the air conditioner. For example, when the power supply voltage of the air conditioner drops to 150V, the embodiment can control the output voltage of the inverter to be maintained between 170V and 220V, so that the capacity of the air conditioner is increased below the capacity under normal working conditions; the embodiment can also control the output voltage of the inverter to be maintained between 220V and 260V, so that the capacity of the air conditioner is larger than that under normal working conditions. Here, the present embodiment may determine that different compensation control schemes are performed on the capacity of the air conditioner according to actual requirements.
Further, the output voltage of the inverter is controlled according to the threshold range where the ambient temperature is, as shown in the present embodiment, to perform compensation control on the capacity of the air conditioner, including, but not limited to, the following steps:
and under the condition that the ambient temperature is smaller than the preset temperature, controlling the output voltage of the inverter to be a second voltage, wherein the second voltage is equal to the preset voltage.
Specifically, when the ambient temperature is less than the preset temperature, the current capacity of the air conditioner is greater than the corresponding capacity at the preset temperature, so that only the output voltage of the inverter is required to be controlled to be equal to the preset voltage.
Here, as the outdoor ambient temperature rises, the power of the air conditioner is greatly reduced since the ambient temperature is between 43 ℃ and 48 ℃, and the power of the air conditioner is reduced more greatly as the ambient temperature is higher, so that the present embodiment determines that the preset temperature is 43 ℃ to 48 ℃. The predetermined temperature may be, for example, 43 ℃, 45 ℃, 46 ℃, 47 ℃, 48 ℃, or the like, and is not particularly limited herein.
Because the capacity of the air conditioner is inversely related to the air outlet temperature of the air conditioner, the embodiment can correspondingly configure the air conditioner with the most suitable power supply scene according to different environments of the air conditioner, and better user experience is achieved while the performance of the air conditioner is ensured.
Further, the method shown in this embodiment further includes: acquiring the air outlet temperature of the air conditioner; under the condition that the power supply voltage is greater than or equal to the preset voltage, determining that the wind temperature is a first target temperature, wherein the difference between the first target temperature and the user set temperature is less than or equal to 1 ℃; and performing control on the air outlet temperature of the air conditioner according to the first target temperature.
Specifically, when the power supply voltage is greater than or equal to the preset voltage, the air conditioner has a relatively high capacity of refrigerating or heating, and the embodiment can quantitatively control the air outlet temperature of the air conditioner according to the requirement of each user on the ambient temperature so as to achieve relatively high experience.
Here, the present embodiment can maintain the difference between the outlet air temperature of the air conditioner and the user-set temperature within 1 ℃ based on the above control. The embodiment may control the outlet air temperature of the air conditioner to reach the first target temperature by adjusting the frequency of operation of the compressor and/or adjusting the opening of the throttle valve.
Further, when the power supply voltage is reduced, in order to timely perform early warning prompt, the method shown in the embodiment further includes: and under the condition that the power supply voltage is smaller than the preset voltage, sending an early warning indication to the user terminal or the power supply terminal.
Specifically, when early warning is performed to the user side, the embodiment can perform early warning to the user in any mode of on-site audible and visual warning, voice prompt and light prompt, and also can wirelessly send early warning information to a mobile phone of the user so as to perform remote early warning prompt to the user.
Meanwhile, when early warning is performed on the power supply end, the embodiment can send early warning information to a client of a power supply company or a mobile phone of an operation and maintenance person in a wired or wireless mode so as to perform remote early warning prompt on the power supply end.
