Description
Technical Field
The application relates to the technical field of air conditioner defrosting, for example, to a control method and device for air conditioner defrosting, an air conditioner and a server.
Background
Along with the improvement of living standard of people, air conditioning equipment has also walked into thousands of households, the use of domestic air conditioners and central air conditioners is more and more common, the requirement of users on the comfort level of the air conditioner is also more and more high, the problems existing in the use process of the air conditioner are also gradually exposed, and one of the problems is the problem that an outdoor unit of the air conditioner is frosted and frozen when the air conditioner operates in severe cold climate. When the air conditioner operates in a low-temperature area or an area with large wind and snow, the condensed water flow on the outer surface of the condenser of the outdoor unit can drop on the base plate, the condenser and the base plate of the air conditioner can be frozen under the condition that the air conditioner operates for a long time, the condensed ice layer on the outdoor unit can obstruct the heat exchange between the internal refrigerant and the outdoor environment, the refrigerating efficiency of the air conditioner is reduced, in order to ensure the heating effect of the air conditioner, the air conditioner has to operate with increased power, and the extra consumption of electric energy and the use cost of a user are increased.
Therefore, some conventional air conditioners have a defrosting function to solve the problem of frost and ice formation of an outdoor unit of the air conditioner, for example, the outdoor unit is heated by a heating device provided in the outdoor unit, or an outdoor heat exchanger is defrosted and de-iced by a high-temperature refrigerant discharged from a compressor. Here, before the air conditioner starts the defrosting function, the air conditioner generally determines whether a temperature condition in which frost is easily condensed has been reached by combining the temperature of the external coil detected by the outdoor sensor with the frost point temperature, and then determines whether the defrosting function is started.
In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related art: the air conditioner generally uses the magnitude of the external environment temperature compared with the frost point temperature as the judgment condition for judging whether the air conditioner needs defrosting; the disadvantage of this method is that because a fixed value of frost point temperature is mostly used, and the frosting degree of the outdoor unit of the air conditioner is affected by various complex factors such as weather and running state of the air conditioner, if it is determined and controlled by this method whether the air conditioner needs defrosting, there will be a large error with the actual frosting state of the air conditioner, which easily causes the problems of false triggering and frequent triggering of the defrosting function, and thus the requirement of the air conditioner for precisely controlling and triggering the defrosting function cannot be met.

and S102, controlling the air conditioner to carry out defrosting judgment on whether a defrosting process is triggered or not based on the temperature correction data.
In an alternative embodiment, the temperature correction data is a corrected frost point temperature. The step 102 of performing the defrosting judgment includes: acquiring the outdoor environment temperature of the environment where the air conditioner is located; comparing the outdoor environment temperature with the corrected frost point temperature; if the outdoor environment temperature is less than or equal to the corrected frost point temperature, controlling the air conditioner to trigger and execute a defrosting process; and if the outdoor environment temperature is greater than the corrected frost point temperature, controlling the air conditioner not to trigger the defrosting process.

Here, each air conditioner product has a unique identification code, and the air conditioner can send the position data and the identification code thereof to the server together, so that the server binds the corresponding relationship between the identification code and the position data; therefore, before the server sends the temperature correction data to the air conditioner corresponding to the identification code, the position data corresponding to the air conditioner can be obtained in a database searching mode, and then the meteorological data of the area where the air conditioner is located is obtained according to the position data, so that the meteorological data are used for correcting the temperature parameters.
