Description
Technical Field
The present application relates to the field of air conditioner defrosting technologies, and for example, to a control method and a control device for air conditioner defrosting, and an air conditioner.
Background
Along with the improvement of living standard of people, air conditioning equipment has also gone 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 conditioners is more and more high, the problems existing in the use process of the air conditioners 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, condensed water on the outer surface of a condenser of the outdoor unit can drip on the base plate, the condenser and the base plate of the air conditioner can be caused to freeze under the condition of long-time operation of the air conditioner, a condensed ice layer on the outdoor unit can block heat exchange between an internal refrigerant and an outdoor environment, the refrigerating efficiency of the air conditioner is reduced, the air conditioner has to operate with increased power in order to ensure the heating effect of the air conditioner, and extra consumption of electric energy and improvement of the use cost of a user are also caused.
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 outdoor environment temperature compared with the frost point temperature as the judgment condition for judging whether the air conditioner needs defrosting or not; the factors influencing the frosting degree of the outdoor unit of the air conditioner not only comprise external environment factors, but also comprise the influence factors of the self state of the air conditioner; therefore, under the partial conditions that the variation of parameters such as the outdoor environment temperature and the like before and after the air conditioner defrosts is small, the working states of all parts of the air conditioner can also change after the air conditioner defrosts at each time, if whether the air conditioner needs defrosting is judged and controlled in the mode, a large error exists between the working states and the actual frosting state of the air conditioner, the problems that the defrosting function is triggered by mistake, the defrosting function is triggered frequently and the like are easily caused, and therefore the requirement that the air conditioner accurately controls and triggers the defrosting function cannot be met.

Here, the outdoor unit of the air conditioner is provided with a temperature sensor, and the temperature sensor can be used for detecting the real-time temperature of the outdoor environment where the outdoor unit is located; in step S101, the real-time temperature of the outdoor environment detected by the temperature sensor is obtained and used as the outdoor environment temperature.
In an alternative embodiment, the first outdoor ambient temperature comprises: and obtaining more than one temperature mean value of the outdoor environment temperature within a first set time after the air conditioner exits the defrosting mode.
Optionally, the first set time period is 30 minutes.
Within the first set time period, the temperature sensor detects more than one outdoor environment temperature, and the air conditioner calculates the temperature mean value of more than one outdoor environment temperature as the first outdoor environment temperature in the step S101;
by taking the temperature mean value as the first outdoor environment temperature, the interference influence of instantaneous and large-amplitude change of the outdoor environment caused by individual factors can be reduced, and the problem of defrosting misjudgment is reduced.
S102, controlling the air conditioner to enter a defrosting mode again according to the first outdoor environment temperature and the second outdoor environment temperature;
in the embodiment of the present disclosure, the second outdoor ambient temperature is an outdoor ambient temperature obtained after the air conditioner is turned on.
Here, after the air conditioner is turned on, the temperature sensor detects the real-time temperature of the outdoor environment, and the air conditioner stores the detected outdoor environment temperature as history data including the outdoor environment temperature acquired after the air conditioner is turned on. In this way, the relevant temperature information in the history data may be called up when step S102 is performed.

by taking the temperature mean value as the second outdoor environment temperature, the interference influence of instantaneous large-amplitude change of the indoor and outdoor environments caused by individual factors in the second set time of the starting operation of the air conditioner can be reduced, and the problem of misjudgment of defrosting is reduced.
The temperature difference between the current outdoor environment temperature of the air conditioner and the outdoor environment temperature when the air conditioner is started can reflect the change situation of the outdoor environment from the starting operation to the current moment of the air conditioner, and the change situation of the outdoor environment can also reflect the influence on whether an air conditioner outdoor unit is frosted or not and the frosting degree from the side surface, so that the control method for defrosting the air conditioner can judge whether the air conditioner enters a defrosting mode according to the outdoor environment temperature of the air conditioner under the condition that the defrosting execution process is completed, compared with the control mode for judging defrosting based on single outdoor environment temperature in the related technology, the method for judging and controlling defrosting by combining the real-time outdoor environment temperature after the defrosting of the air conditioner and the outdoor environment temperature at the initial stage of the starting operation can more accurately control the air conditioner to trigger and execute the defrosting process, the problems of false triggering, frequent triggering and the like of the defrosting process in the related technology are reduced.
