Description

Control method and device for defrosting of air conditioner and air conditioner

Technical Field

The present disclosure relates to the field of air conditioner defrosting technologies, and for example, to an air conditioner and a defrosting control method thereof.

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 the outdoor unit of the air conditioner, for example, the outdoor unit is heated by a heating device provided in the outdoor unit, or the outdoor heat exchanger is defrosted and de-iced by a high-temperature refrigerant discharged from the compressor in a cooling mode. 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: in the related art, in order to avoid the problem that the normal heating operation is affected by the continuous and frequent starting of the defrosting function of the air conditioner in the low-temperature environment, the defrosting function of the air conditioner is generally set to be not started within a fixed time after the defrosting is finished, for example, a defrosting time interval of 20 minutes and 30 minutes is set; the method has the disadvantages that factors influencing the frosting degree of the outdoor unit of the air conditioner not only include external environment factors, but also include the influence factors of the self state of the air conditioner, because the working state of each part of the air conditioner can also change after defrosting is finished every time, if the defrosting function is still controlled to be started by the fixed defrosting time interval, a larger error can exist between the working state and the actual frosting state of the air conditioner actually, for example, under the extremely severe cold weather condition, if the defrosting time interval is set for a longer time, the air conditioner is easy to condense more frost in the time period of the defrosting time interval, and at the moment, the air conditioner cannot start the defrosting function immediately due to the limitation of the defrosting time interval, so the normal use of the air conditioner can be influenced.

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, under the condition that an air conditioner completes a defrosting process, acquiring a first time parameter related to a current frosting state and a second time parameter related to a historical frosting state of the air conditioner;

in the embodiment of the present disclosure, the operation of correcting the defrosting interval duration is performed after the air conditioner has completed a certain defrosting process.

Here, the first time parameter associated with the current frosting state is a time parameter acquired by the air conditioner after a defrosting process is completed, which represents a time variation condition of the air conditioner after the defrosting process is completed, and is associated with a frosting condition of the air conditioner after the defrosting process is completed; the second time parameter associated with the historical frosting state is a time parameter acquired in the whole operation process of the air conditioner, represents the time change condition of the air conditioner in the whole operation process and is associated with the frosting condition in the whole operation process of the air conditioner; here, the disclosed embodiments are applied to heating conditions where frosting may be a problem. In the air conditioner in the embodiment of the present disclosure, after the air conditioner completes a certain defrosting process, the defrosting interval duration is modified according to the first time parameter and the second time parameter, and the modified defrosting interval duration is a judgment operation on the interval duration condition before defrosting judgment of a next defrosting process to be executed.

Optionally, the air conditioner in the embodiment of the present disclosure is provided with a timing module, and the timing module may be configured to count a first time parameter associated with a current frosting state and a second time parameter associated with a historical frosting state; and the two time parameters counted by the timing module of the air conditioner are both stored as historical operation data.

S102, correcting the defrosting interval time from the current defrosting process to the next defrosting process based on a first time parameter related to the current frosting state and a second time parameter related to the historical frosting state;

in some optional embodiments, the modified defrosting interval duration is a preset duration value of one or more different duration values pre-stored in the air conditioner, such as 2 minutes, 7 minutes, and the like; in step S102, the air conditioner corrects the selected set time length value based on the first time parameter and the second time parameter;

in other alternative embodiments, the corrected defrosting interval duration is the defrosting interval duration between the defrosting process executed by the air conditioner and the previous defrosting process; therefore, in the embodiment of the present disclosure, before executing step S102, the steps of the control method of the embodiment of the present disclosure further include: and acquiring the defrosting interval duration between the defrosting process executed by the air conditioner and the previous defrosting process, and taking the defrosting interval duration as the defrosting interval duration to be corrected.

The air conditioner is provided with a timing module, and the timing module can be used for counting the interval duration between the completion time of the defrosting process executed by the air conditioner and the current time; in the above embodiment, the defrosting interval duration to be corrected is the interval duration between two adjacent defrosting processes, that is, the duration between the completion time of the previous defrosting process and the start time of the current defrosting process.

Optionally, the step S102 includes: matching to obtain a duration correction value corresponding to a ratio interval based on the ratio interval of the first time parameter and the second time parameter and a preset incidence relation; the incidence relation is configured to represent the corresponding relation between one or more than one ratio interval and the duration correction value; and correcting the defrosting interval duration based on the duration correction value obtained by matching.

S103, under the condition that the interval duration condition is determined to be met based on the corrected defrosting interval duration, controlling the air conditioner to perform defrosting judgment whether to trigger the next defrosting process.

In the embodiment of the present disclosure, the interval duration condition includes that the interval duration between the completion time of the defrosting process that the air conditioner has executed and the current time is greater than or equal to the corrected defrosting interval duration. Therefore, if the air conditioner meets the interval duration condition, the air conditioner is controlled to perform defrosting judgment on whether the next defrosting process is triggered; and if the air conditioner does not meet the interval duration condition, controlling the air conditioner not to perform defrosting judgment on whether to trigger the next defrosting process.

In some optional embodiments, the specific implementation process of controlling the air conditioner to perform the defrosting judgment whether to trigger the next defrosting process in step S103 includes: under the condition that the air conditioner meets the preset defrosting condition, judging that the air conditioner triggers the next defrosting process; and under the condition that the air conditioner does not meet the preset defrosting condition, judging that the air conditioner does not trigger the next defrosting process.

Optionally, the preset defrosting condition includes that the temperature of the outdoor coil of the air conditioner is lower than the frost point temperature.

Here, to control the air conditioner to perform the defrosting judgment whether to trigger the next defrosting process, the steps of the embodiment of the present disclosure further include: acquiring the temperature of an outdoor coil of an air conditioner; comparing the temperature of the outdoor coil with the frost point temperature, and judging that the air conditioner triggers the next defrosting process under the condition that the temperature of the outdoor coil is less than the frost point temperature; and under the condition that the temperature of the outer coil is greater than or equal to the frost point temperature, judging that the air conditioner does not trigger the next defrosting process.

In the embodiment of the present disclosure, the outdoor unit of the air conditioner is further provided with a temperature sensor, and the temperature sensor can be used for detecting the real-time outdoor coil temperature of the coil of the outdoor unit; therefore, the step is to obtain the temperature of the outdoor coil detected by the temperature sensor;

illustratively, the set frost point temperature is-1 ℃; when the temperature of the outdoor coil acquired from the temperature sensor is-2 ℃, the temperature is lower than-1 ℃ below zero 2 ℃, and then the air conditioner is judged to trigger the next defrosting process; and when the temperature of the outdoor coil acquired from the temperature sensor is 3 ℃, the temperature of minus 1 ℃ is less than 3 ℃, and the next defrosting process triggered by the air conditioner is judged.

Here, the flow steps of the control method of the present application further include: acquiring the execution times of a defrosting process of the air conditioner after the starting; under the condition that the execution times of the defrosting process is equal to 0, controlling the air conditioner to judge whether to trigger the defrosting process of the next time based on the temperature of the outdoor coil pipe and the frost point temperature; in the case where the number of times of execution of the defrosting process is not equal to 0, the control processes of steps S101 to S103 are executed.

Counting the execution times of the defrosting process after the air conditioner is started, wherein the initial value of counting is 0; the counting is increased by 1 every time the air conditioner executes a defrosting process; therefore, after the air conditioner is started at the starting time and before the defrosting process is executed for the first time, the counting of the defrosting process by the air conditioner is 0, and at the moment, the air conditioner is controlled to perform defrosting judgment whether to trigger the next defrosting process or not based on the temperature of the outdoor coil pipe and the frost point temperature.

And when the air conditioner is shut down after the operation is finished, the air conditioner clears the count of the defrosting process.

Defrosting time (unit: minute)	Duration correction value (Unit: minute)
		t/T＜d1	5
d1≤t/T＜d2	0
		d2＜t/T	-5

and S208, controlling the air conditioner to judge whether the next defrosting process is triggered.

In the embodiment of the present disclosure, the specific execution process of step S208 may refer to the foregoing embodiments, which are not described herein again.

According to the control method for defrosting of the air conditioner, the preset incidence relation is used for searching and matching the duration correction value of the ratio of the defrosting duration corresponding to the defrosting execution flow of the air conditioner to the accumulated running duration, and then the defrosting interval duration is corrected according to the duration correction value, so that the time interval of the adjacent defrosting flows adaptive to the current working condition can be accurately adjusted, and the air conditioner can trigger the defrosting flow of the air conditioner more accurately.

s302, acquiring the defrosting duration of the previous defrosting process of the defrosting process executed by the air conditioner at this time;

s303, calculating the ratio of the first defrosting time length to the second defrosting time length;

here, the first defrosting time period acquired in step S301 of the air conditioner is set to t1, the second defrosting time period acquired in step S302 is set to t2, and the ratio of the first defrosting time period to the second defrosting time period calculated in step S303 is t1/t 2;

s304, matching to obtain a time length correction value corresponding to a ratio interval based on the ratio interval of the ratio of the first defrosting time length to the second defrosting time length and a preset second incidence relation;

in the embodiment of the present disclosure, the second association relationship is configured to represent a corresponding relationship between one or more ratio intervals and the duration correction value;

for example, table 2 shows an optional ratio interval and duration correction value.

Interval of ratio	Duration correction value (unit: minute)
		(t1/t2)＜d1	5
d1≤(t1/t2)＜d2	0
		d2≤(t1/t2)＜d3	-2
d3＜(t1/t2)	-5

Therefore, in step S304, the air conditioner may search and match the duration correction value of the corresponding ratio interval through the table.

And S305, correcting the defrosting interval time to be corrected based on the time correction value obtained by matching.

In the embodiment of the present disclosure, the sum of the defrosting interval duration to be corrected and the duration correction value is calculated in step S305, so as to obtain the corrected defrosting interval duration.

S306, acquiring the interval duration between the completion time of the defrosting process executed by the air conditioner and the current time;

s307, judging whether the corrected defrosting interval duration meets an interval duration condition, if so, executing a step S308; if not, returning to the step S306;

and S308, controlling the air conditioner to judge whether the next defrosting process is triggered.

In the embodiment of the present disclosure, the specific execution process of step S308 may refer to the foregoing embodiments, which are not described herein again.

The control method for defrosting of the air conditioner, which is disclosed in the embodiment of the disclosure, searches for a duration correction value matching a corresponding ratio interval through a preset incidence relation, and further corrects the duration of a defrosting interval according to the duration correction value, wherein the ratio interval can reflect the duration change of two defrosting processes which have been executed by the air conditioner recently, and under the condition of a larger ratio, the frosting degree of the air conditioner is aggravated, so that the corrected defrosting interval has a shorter duration, and the next defrosting process can be triggered more easily, and thus, the air conditioner triggers the defrosting process adaptive to the current working condition more accurately.

Fig. 4 is a flowchart illustrating a control method for defrosting an air conditioner according to another embodiment of the present disclosure.

As shown in fig. 4, the embodiment of the present disclosure provides a control method for defrosting an air conditioner, where the flow defined by the control method is performed after the air conditioner has completed a certain defrosting flow; the method specifically comprises the following steps:

s401, responding to the completion of the defrosting process executed by the air conditioner, and acquiring a first accumulated operation time of a heating mode after the air conditioner executes the defrosting process;

s402, acquiring a second accumulated running time of a heating mode before a defrosting process executed by the air conditioner at this time;

s403, calculating the ratio of the first accumulated running time length to the second accumulated running time length;

here, the first accumulated operation defrosting time period obtained in step S401 of the air conditioner is set to T1, the second accumulated operation time period obtained in step S402 is set to T2, and the ratio of the first accumulated operation time period to the second accumulated operation time period calculated in step S403 is T1/T2;

s404, matching to obtain a time length correction value corresponding to a ratio interval based on the ratio interval of the first accumulated running time length and the second accumulated running time length and a preset third correlation;

in an embodiment of the disclosure, the third correlation is configured to represent a correspondence between one or more ratio intervals and the duration correction value.

For example, table 3 shows an optional ratio interval and duration correction value.

Interval of ratio	Duration correction value (unit: minute)
		(T1/T2)＜d1	3
d1≤(T1/T2)＜d2	0
		d2≤(T1/T2)＜d3	-1
d3＜(T1/T2)	-3

Therefore, in step S404, the air conditioner may search and match the duration correction value of the corresponding ratio interval through the table.

And S405, correcting the defrosting interval time to be corrected based on the time correction value obtained by matching.

In the embodiment of the present disclosure, in step S405, the sum of the defrosting interval duration to be corrected and the duration correction value is calculated, so as to obtain the corrected defrosting interval duration.
