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, 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, heating the outdoor unit by a heating device provided in the outdoor unit, or defrosting and melting ice in an outdoor heat exchanger 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 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 outer ring temperature and the like before and after the defrosting of the air conditioner is small, the working state of each part of the air conditioner is changed after the defrosting of the air conditioner is finished every time, if the air conditioner is judged and controlled to defrost in the mode, a large error exists between the working state and the actual frosting state of the air conditioner, the problems that the defrosting function is triggered by mistake and triggered frequently are easily caused, and the like, so that the requirement that the defrosting function is triggered by the accurate control of the air conditioner cannot be met.

Fig. 1 is a schematic flow chart of a control method for defrosting an air conditioner according to an embodiment of the present disclosure.
As shown in fig. 1, an embodiment of the present disclosure provides a control method for defrosting an air conditioner, including:
s101, acquiring the temperature of an outdoor coil of an air conditioner when the air conditioner operates in a heating mode;
in the embodiment of the disclosure, 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 a coil pipe of the outdoor unit; step S101, acquiring the real-time temperature of the coil detected by the temperature sensor, and taking the real-time temperature as the temperature of the outdoor coil;
here, when the problem of frost formation of the outdoor unit of the air conditioner occurs, the outdoor unit of the air conditioner is generally in a cold climate in winter, and at this time, the air conditioner operates in a heating mode.
And S102, controlling the air conditioner to enter a defrosting mode when the preset condition is met according to the temperature of the outdoor coil.
Here, the preset conditions include: the accumulated duration of the outdoor coil temperature meeting the preset frosting temperature condition meets the preset duration condition.
Optionally, the preset frosting temperature condition includes: the outdoor coil temperature is less than the frost point temperature.
Here, when the temperature of the outdoor coil meets the preset frosting temperature condition, the temperature of the outdoor unit of the air conditioner is low, frost is gradually condensed on the outdoor unit, and the air conditioner may have the problem of frosting which affects the performance of the air conditioner; and under the condition that the temperature of the outdoor coil pipe does not meet the preset frosting temperature condition, the temperature of the outdoor unit of the air conditioner is higher, and the problem of frosting does not exist on the outdoor unit or the frosting amount is less.
Optionally, the control method further includes: acquiring the outdoor environment temperature of the air conditioner; and calculating according to a dew point calculation formula to obtain a dew point temperature, and taking the dew point temperature as the frost point temperature.
Here, the dew point temperature can be calculated by the following dew point calculation formula:
Tes＝A*Tai+B；
where Tes is the dew point temperature, A is the coefficient of calculation of the outdoor ambient temperature, Tai is the outdoor ambient temperature, and B is the calculation constant.
The preset condition in step S102 of the embodiment of the present disclosure further introduces a judgment condition of a preset duration condition, and the air conditioner is controlled to enter the defrosting mode under the condition that the accumulated duration time that the outdoor coil temperature determines to satisfy the preset frosting temperature condition satisfies the preset duration condition; and under the condition that the accumulated duration time of the outdoor coil temperature which is determined to meet the preset frosting temperature condition does not meet the preset duration time condition, the air conditioner is controlled not to enter the defrosting mode, and the current running state is kept unchanged, so that the problem that the defrosting mode is mistakenly triggered due to the fact that the outdoor coil temperature changes along with the short time caused by the short-time change of the running state of the air conditioner can be solved.
In the embodiment of the present disclosure, the preset duration condition includes: the accumulated duration is greater than or equal to the set duration. Alternatively, the set time period is 35 to 45 minutes.
Here, when the temperature of the outdoor coil pipe determines that the accumulated duration time satisfying the preset frosting temperature condition satisfies the preset duration time condition, it may be determined that more frost is condensed on the outdoor unit of the air conditioner, and the influence on the air conditioning heat running performance is large, so the air conditioner is controlled to enter a defrosting mode to remove the redundant frost on the outdoor unit and avoid the excessive accumulation of the frost on the outdoor unit.
