Description
Technical Field
The application relates to the technical field of intelligent air conditioners, in particular to a method and a device for controlling heating of an air conditioner and the air conditioner.
Background
When the air conditioner is used for heating operation in winter, the temperature of the outdoor heat exchanger is lower. In the case of low outdoor temperature, the surface of the outdoor heat exchanger is easy to frost. The frosting affects the heating effect of the air conditioner. At present, some air conditioners heat an outdoor heat exchanger in an electric heating manner to melt a frost layer. Some air conditioners can heat the outdoor heat exchanger to melt the frost layer by running a refrigeration mode. When the refrigeration mode is adopted for defrosting, the air deflector is closed to avoid blowing cold air to the indoor. However, when the defrosting time is longer, the indoor temperature is inevitably reduced, and the heating effect of the air conditioner is affected.
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: when the air conditioner defrosts the outdoor heat exchanger, the heating effect is easily influenced, and the fluctuation of the indoor temperature is large.

When the air conditioner operates in the heating mode, the temperature of the outdoor heat exchanger is low, and if the outdoor environment temperature is low and the humidity is high, the outdoor heat exchanger is prone to frosting. When the air conditioner operates in a defrosting mode, the indoor air deflector moves to a cold air prevention position, the air conditioner operates in a refrigeration cycle, and the temperature of the outdoor heat exchanger rises, so that a frost layer is melted. However, the temperature of the indoor heat exchanger is lowered at this time, which affects the indoor temperature. The indoor side heat loss is sometimes compensated by turning on the auxiliary heating means.
After defrosting is finished, the indoor air deflector is controlled to act according to cold air prevention, the auxiliary electric heating device is continuously started until the cold air prevention is finished, and the auxiliary electric heating device is recovered to the set state of the previous period.
Referring to fig. 1, an embodiment of the present disclosure provides a method for controlling heating of an air conditioner, including:
s10, obtaining a shutdown mode of the air conditioner in the current heating state;
and S20, if the shutdown mode is remote control shutdown, if the outdoor environment temperature is less than a first preset value, the first preset value is greater than zero, and the outdoor relative humidity exceeds a set value, controlling the air conditioner to defrost and then shutdown according to the current heating operation time length, or determining that the next heating operation time length is greater than or equal to the preset time length and shutdown.
The embodiment of the disclosure can provide a scheme for controlling defrosting of an air conditioner or determining the next heating operation time length according to the shutdown mode of the air conditioner in the current heating state. Specifically, the shutdown mode of the air conditioner in the current heating state can be obtained, and the air conditioner is controlled to defrost and then shutdown according to the outdoor environment temperature, the outdoor relative humidity and the current heating operation time length, or the next heating operation time length is determined to be greater than or equal to the preset time length and shutdown is performed.
In the embodiment of the disclosure, when the shutdown mode of the air conditioner in the current heating state is remote shutdown, if the outdoor environment condition satisfies that the outdoor environment temperature is less than a first preset value, the first preset value is greater than zero, and the outdoor relative humidity exceeds a set value, the air conditioner is controlled to defrost and then shutdown according to the current heating operation time length, or the next heating operation time length is determined to be greater than or equal to the preset time length and shutdown is performed. Therefore, the outdoor heat exchanger can be defrosted after a user finishes the heating mode, or the next heating operation time is limited to a longer time, so that the heating operation time is prolonged, the air conditioner is prevented from starting defrosting under the condition that the next heating operation time is shorter, and the indoor temperature is prevented from generating larger fluctuation; and on the premise of keeping the air conditioning heat effect, the air conditioning outdoor heat exchanger is defrosted.
The shutdown mode of the air conditioner in the current heating state means that the air conditioner may be shut down when the air conditioner is in the heating mode currently running. The reason for shutdown may come from a remote control instruction of a user, or may come from automatic shutdown of the air conditioner, or a power failure situation occurs, so that the air conditioner has multiple shutdown modes during shutdown.
As an example, the obtaining module is configured to obtain a shutdown mode of the air conditioner in the current heating state.
The air conditioner enters a standby state when being shut down by remote control, and the air conditioner still has certain running power in the standby state. The power of the air conditioner can be detected by arranging the power sensor, when the power accords with the standby power, a signal is sent to the acquisition module, and when the acquisition module receives a shutdown signal and a signal which accords with the standby power, the air conditioner is determined to be remotely controlled to be shut down. The current of the air conditioner is zero when the power is cut off and the air conditioner is shut down. The current of the air conditioner can be detected by arranging the current sensor, when the current is zero, the current sensor sends a signal to the acquisition module, and when the acquisition module receives the signal that the current is zero, the air conditioner is determined to be powered off and shut down.
As an example, a controller is provided, where the shutdown mode is remote shutdown, and if the outdoor ambient temperature is less than a first preset value, the first preset value is greater than zero, and the outdoor relative humidity exceeds a set value, the controller is configured to control the air conditioner to defrost and then shutdown according to the current heating operation time length, or determine that the next heating operation time length is greater than or equal to the preset time length and shutdown. The controller controls the air conditioner to defrost or determines the next heating operation time length, and controls the air conditioner to be shut down.
In the actual treatment process, a first preset value of the outdoor environment temperature can be preset, the first preset value is larger than zero, and the outdoor heat exchanger has the possibility of frosting under the condition that the outdoor environment temperature is smaller than the first preset value; and under the condition that the outdoor environment temperature is greater than or equal to the first preset value, the frosting of the outdoor heat exchanger is avoided.
As an example, the first preset value is 5 ℃. By adopting 5 ℃ as the first preset value, whether the outdoor heat exchanger is likely to frost or not can be accurately divided.
The outdoor heat exchanger is characterized in that the outdoor relative humidity is divided except for setting a first preset value, a set value is preset, and if the outdoor environment temperature is smaller than the first preset value and the outdoor relative humidity is larger than or equal to the set value, the outdoor environment temperature is considered to be lower, the outdoor relative humidity is considered to be larger, and the outdoor heat exchanger has a frosting phenomenon to a lesser extent. If the outdoor environment temperature is less than the first preset value and the outdoor relative humidity is less than the set value, the frosting possibility is extremely low.
As an example, the set value is 80%. The frosting possibility of the outdoor heat exchanger can be accurately judged by adopting 80% as a set value of the outdoor relative humidity and matching with the outdoor environment temperature.
As an example, the preset time period is 30 min. Therefore, the indoor temperature can be increased and kept stable when the next heating operation is enough, and the large indoor temperature fluctuation caused by defrosting due to short heating time is avoided.
In some embodiments, controlling the air conditioner to defrost and then shut down according to the current heating operation time length, or determining that the next heating operation time length is greater than or equal to the preset time length and shutting down includes:
under the condition that the current heating operation time is longer than or equal to the first time, controlling the air conditioner to defrost firstly and then shut down;
and under the condition that the current heating operation time length is less than the first time length, determining that the next heating operation time length is more than or equal to the preset time length and shutting down.
According to the embodiment of the invention, under the condition that the current heating operation time is long, the air conditioner is controlled to defrost firstly and then shut down, and under the condition that the current heating operation time is short, the defrosting of the air conditioner is not controlled, but the next heating operation time is determined. When the air conditioner is long in heating operation time, the indoor temperature is high and stable, the air conditioner is controlled to defrost at the moment, and the indoor temperature cannot fluctuate greatly. When the heating operation time of the air conditioner is short, the indoor temperature may not be very high, and at the moment, the defrosting of the air conditioner is not controlled so as to avoid the further reduction of the indoor temperature and the occurrence of large fluctuation, but the next heating operation time is determined to be longer than or equal to the preset time, so that the air conditioner can be prevented from operating for defrosting when the next heating operation time is short, and the influence on the next heating operation effect is avoided.
The condition of the current heating operation time length is divided by the first time length, when the current heating operation time length is larger than or equal to the first time length, the air conditioner is considered to have operated for enough heating time, the indoor temperature is at a proper temperature and the temperature is stable, and at the moment, if the air conditioner is controlled to defrost, the indoor temperature cannot generate large fluctuation. When the current heating operation time is shorter than the first time, the heating time of the air conditioner is considered to be insufficient, the indoor temperature is unstable, and at the moment, if the defrosting of the air conditioner can be controlled, the indoor temperature can generate large fluctuation.
In some embodiments, the method for determining the first duration comprises:
under the condition that the outdoor environment temperature is less than zero, the first time length is a first value, and the first value is less than 60 min;
and under the condition that the outdoor environment temperature is greater than or equal to zero and less than a first preset value, the first time length is a second value, and the second value is greater than the first value and greater than 60 min.
This disclosed embodiment adopts certain rule to confirm first time length, sees that the comparison result according to outdoor temperature and zero on the whole, confirms that first time length is first value or second value. In this way, the first period of time can be determined more accurately, taking into account the factors of the outdoor ambient temperature. The first time length determined by the embodiment of the disclosure can be used as the judgment standard of the current heating operation time length, so that whether the indoor temperature fluctuates greatly due to defrosting can be evaluated more accurately, and the air conditioner can be controlled accurately to defrost or not defrost and only the next heating operation time length is determined.
As an example, the first value is 45min and the second value is 90 min.
In some embodiments, controlling the air conditioner to defrost and then shut down according to the current heating operation time length, or determining that the next heating operation time length is greater than or equal to the preset time length and shutting down includes:
under the conditions that the outdoor environment temperature is less than zero and the current heating operation time is greater than or equal to 45min, controlling the air conditioner to defrost and then shut down;
and under the condition that the outdoor environment temperature is less than zero and the current heating operation time is less than 45min, determining that the next heating operation time is more than or equal to the preset time and shutting down.
Through this embodiment, under the condition that outdoor ambient temperature is less than zero, can avoid indoor temperature fluctuation great.
In some embodiments, controlling the air conditioner to defrost and then shut down according to the current heating operation time length, or determining that the next heating operation time length is greater than or equal to the preset time length and shutting down includes:
under the conditions that the outdoor environment temperature is greater than or equal to zero and smaller than a first preset value and the front heating operation time is greater than or equal to 90min, controlling the air conditioner to defrost firstly and then shut down;
and under the conditions that the outdoor environment temperature is greater than or equal to zero and less than a first preset value and the current heating operation time is less than 90min, determining that the next heating operation time is greater than or equal to the preset time and shutting down.
Through the embodiment, under the condition that the outdoor environment temperature is greater than or equal to zero and less than the first preset value, the situation that the indoor temperature fluctuates greatly can be avoided.
As shown in fig. 2, in some embodiments, in the case that the current heating operation time period is less than the first time period, the method further includes:
s30, accumulating the current heating operation time length to the next heating operation time length;
and S40, controlling the air conditioner to defrost under the condition that the accumulated sum of the current heating operation time length and the next heating operation time length is larger than the preset time length and the defrosting is not performed in the current heating operation period and the next heating operation period.
According to the embodiment of the disclosure, under the condition that the current heating operation time length is less than the first time length, the current heating operation time length is accumulated to the next heating operation time length, and if the accumulated sum is larger, the fact that the air conditioner does not defrost for a long time is indicated, the air conditioner is controlled to defrost. Thus, the air conditioner can be prevented from frosting seriously, and the cleaning is difficult. And if the sum of the accumulations is small, which indicates that the current frosting condition of the air conditioner is not serious, the defrosting is not needed. Through the scheme of the embodiment of the disclosure, the air conditioner can be forced to defrost under the condition that the air conditioner does not defrost for a long time, and the air conditioner is prevented from frosting seriously.
As an example, the predetermined time period is 8 h. And if the accumulated sum is more than 8h and defrosting is not performed in the period, the air conditioner is forced to operate for defrosting in order to avoid serious frosting of the outdoor heat exchanger.
Illustratively, the step of accumulating the current heating operation time length into the next heating operation time length is to, if the current heating operation time length is 30min and the next heating operation time length is 45min, the accumulated sum is 30+ 45-75 min.
In some embodiments, in the case that the shutdown mode is remote-controlled shutdown, the method further includes: and if the outdoor ambient temperature is greater than or equal to the first preset value, controlling the air conditioner to directly blow the waste heat and then shut down.
According to the embodiment of the disclosure, under the condition that the outdoor environment temperature is slightly high, the air conditioner is controlled to directly blow the waste heat and then shut down, so that the outdoor heat exchanger can be heated up under the action of the outdoor temperature after being shut down, a frost layer on the surface of the outdoor heat exchanger can be melted, and the air conditioner does not need to be controlled to defrost; the waste heat is blown to the indoor through the air conditioner, and the large fluctuation of the indoor temperature is avoided.
Under the condition that the shutdown mode is remote control shutdown, the indoor fan of the air conditioner can still be controlled to rotate to blow the waste heat.
In some embodiments, the method for controlling heating of an air conditioner further includes: and under the condition that the shutdown mode is power-off shutdown, if the outdoor environment temperature is less than zero and the outdoor relative humidity exceeds a set value, determining that the next heating operation time length is more than or equal to the preset time length, and accumulating the current heating operation time length to the next heating operation time length.
In the embodiment of the disclosure, under the condition of power-off shutdown, when the outdoor environment temperature is low and the outdoor relative humidity is high, the frosting tendency of the outdoor heat exchanger is considered to be large, but because the air conditioner is powered-off shutdown and has different properties from remote control shutdown, the air conditioner cannot be controlled to defrost any more, the next heating operation time length is determined, and the current heating operation time length is accumulated to the next time. Therefore, the air conditioner has the possibility of operating the defrosting process only after the next heating operation time at least reaches the preset time so as to avoid large indoor temperature fluctuation. And the current heating operation time length is accumulated to the next time, and the air conditioner is controlled to forcedly defrost under the condition of larger accumulated sum, so that the frosting of the outdoor heat exchanger is avoided seriously.
As an example, the set value is 80%. As an example, the preset time period is 30 min.
Under the condition of power failure shutdown, the next heating operation time length can be determined and the current heating operation time length can be accumulated through the power failure memory function in the prior art.
In some embodiments, in the case that the shutdown mode is power-off shutdown, the method further includes: if the outdoor environment temperature is greater than or equal to zero and less than the first preset value, and the outdoor relative humidity exceeds a set value, determining that the next heating operation time length is greater than or equal to the preset time length under the condition that the power-off time length is less than or equal to the set time length, and accumulating the current heating operation time length into the next heating operation time length.
In the embodiment of the disclosure, under the conditions that the outdoor environment temperature is greater than or equal to zero but less than a first preset value and the outdoor relative humidity is relatively high, the outdoor heat exchanger is considered to have a certain frosting tendency but not be very large; at this time, if the power-off time is short, the next heating operation time is determined to be greater than or equal to the preset time, and the current heating operation time is accumulated to avoid large indoor temperature fluctuation.
And if the power-off time length is longer, namely the power-off time length is greater than the set time length, clearing the current heating operation time length and avoiding accumulation. Because the air conditioner does not operate to heat under the condition that the power-off time is long, the outdoor heat exchanger can automatically melt even if a frost layer exists in the outdoor heat exchanger under the condition that the outdoor environment temperature is greater than zero, subsequent forced defrosting is not needed, defrosting can not be started within a short time of next heating starting, and unnecessary fluctuation of the indoor temperature can not be caused.
As an example, the set time period is 24 h. And the 24h is taken as the set time length of the power-off time length, so that the air conditioner can be controlled to defrost under the condition of avoiding influencing the heating effect.
In some embodiments, in the case that the shutdown mode is power-off shutdown, the method further includes: and if the outdoor environment temperature is less than the first preset value, controlling the air conditioner to defrost under the condition that the accumulated sum of the current heating operation time length and the next heating operation time length is greater than the preset time length and under the condition that the defrosting is not performed during the current heating operation period and the next heating operation period.
According to the embodiment of the disclosure, when the outdoor environment temperature is less than the first preset value and the accumulated sum of the operation time lengths is greater than the preset time length, the air conditioner is considered to be frosted, and in combination with the fact that defrosting is not performed in the current heating operation period and the next heating operation period, the air conditioner is considered to be required to be defrosted, so that the frost layer is prevented from being thicker and thicker, and defrosting of the air conditioner is controlled. Thus, the air conditioner can be prevented from frosting seriously. And if the sum of the accumulations is small, which indicates that the current frosting condition of the air conditioner is not serious, the defrosting is not needed. Through the scheme of the embodiment of the disclosure, the air conditioner can be forced to defrost under the condition that the air conditioner does not defrost for a long time, and the air conditioner is prevented from frosting seriously.
