Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The following will describe a detailed description of an air conditioner control method according to an embodiment of the present application with reference to a specific embodiment, as shown in fig. 1, and the specific steps are as follows:
S101, acquiring the temperature of a first outdoor heat exchanger coil corresponding to an air conditioner in the reverse circulation defrosting process of the air conditioner.
S102, under the condition that the temperature of the first outdoor heat exchanger coil is in a preset temperature range, starting an indoor fan of the air conditioner according to a first preset rotating speed, and meanwhile, acquiring the initial environment temperature of a space where the air conditioner is located.
And S103, after the indoor fan is started, controlling the indoor fan to operate based on the initial ambient temperature and the real-time ambient temperature of the space.
S101 to S103 are collectively described below:
The air conditioner control method provided by the embodiment of the application is used for controlling the indoor fan to be started and operated at a proper time in the reverse circulation defrosting process of the air conditioner, accelerating the heat exchange of the indoor coil, and accelerating the defrosting by utilizing the part of heat, thereby reducing the defrosting time consumption and improving the defrosting efficiency.
And the temperature of the coil pipe of the first outdoor heat exchanger is detected in real time in the reverse circulation defrosting process of the air conditioner.
Specifically, the temperature of the first outdoor heat exchanger coil can be acquired in real time through a preset temperature sensor.
In the embodiment of the application, the time for starting the indoor fan is determined through the temperature of the first outdoor heat exchanger coil, namely, the indoor fan is started according to the first preset rotating speed under the condition that the temperature of the first outdoor heat exchanger coil is in the preset temperature range.
The preset temperature range is a temperature range (generally [ -1,1 ]) which is measured in advance according to experiments, and the experiment shows that under the condition that the temperature of the first outdoor heat exchanger coil is in the preset temperature range, the indoor fan is started to accelerate the indoor coil to exchange heat, so that the defrosting effect on the surface of the outdoor heat exchanger is better. When the temperature of the outdoor heat exchanger coil is out of the preset temperature range, the indoor fan is started to defrost the indoor fan, and consumption is increased due to the fact that the indoor fan is started. For example, a temperature greater than the preset temperature range means a higher temperature, and defrosting is about to be completed or completed, and at this time, the effect of starting the indoor fan on defrosting is not great, and for example, a temperature smaller than the preset temperature range means a temperature too low, and defrosting difficulty is great, and at this time, the effect of starting the indoor fan on defrosting is not great.
Therefore, in the embodiment of the application, the indoor coil heat exchange is accelerated by starting the indoor fan only when the temperature of the first outdoor heat exchanger coil is in the preset temperature range.
The initial ambient temperature refers to the acquired ambient temperature of the space in which the air conditioner is located (e.g., the room in which the air conditioner is located) when the indoor fan is started.
The real-time ambient temperature refers to the ambient temperature of the space where the air conditioner is located, which is obtained in real time after the indoor fan is started.
In the embodiment of the application, the initial environmental temperature is acquired when the indoor fan is started, and the initial environmental temperature is taken as a reference and is compared with the real-time environmental temperature acquired in real time after the indoor fan is started, so that the temperature change condition caused by starting the indoor fan can be obtained. In order to control the indoor fan under the condition of reducing the influence on the indoor temperature, in the embodiment of the application, after the indoor fan is started, the operation of the indoor fan can be controlled based on the initial environment temperature and the real-time environment temperature of the space.
How the indoor fan operation is controlled based on the initial ambient temperature and the real-time ambient temperature of the space will be described in detail in the following embodiments, and will not be described in detail here.
In combination with the above description, in the case that the temperature of the outdoor heat exchanger coil is outside the preset temperature range, the effect on defrosting by operating the indoor fan is not great, but rather the consumption is increased by operating the indoor fan.
To this end, in another embodiment, the method may further comprise the steps of:
And after the indoor fan is started, acquiring the temperature of a second outdoor heat exchanger coil corresponding to the air conditioner, and closing the indoor fan under the condition that the temperature of the second outdoor heat exchanger coil is out of the preset temperature range. Therefore, after the indoor fan is started, the time for closing the indoor fan can be determined according to whether the temperature of the coil pipe of the outdoor heat exchanger is still in a preset temperature range, and consumption is increased due to the operation of the indoor fan under the condition that the defrosting effect is not great by the operation of the indoor fan.
In practical application, for some air conditioners with an upper air outlet and a lower air outlet, the lower air outlet can be closed and only the upper air outlet can be opened during defrosting. Therefore, the heat accumulated at the top of the room can be blown down or absorbed, indoor ineffective heat is effectively utilized, indoor comfort is guaranteed during defrosting, defrosting time is shortened, and defrosting efficiency is improved.
In the embodiment of the application, firstly, the temperature of a first outdoor heat exchanger coil corresponding to an air conditioner is obtained in the reverse circulation defrosting process of the air conditioner, then, under the condition that the temperature of the first outdoor heat exchanger coil is in a preset temperature range, an indoor fan of the air conditioner is started according to a first preset rotating speed, meanwhile, the initial environment temperature of a space where the air conditioner is located is obtained, and after the indoor fan is started, the operation of the indoor fan is controlled based on the initial environment temperature and the real-time environment temperature of the space. Therefore, in the reverse circulation defrosting process of the air conditioner, the indoor coil waste heat is effectively utilized by starting the indoor fan, the heat for defrosting is increased, the defrosting time is shortened, the defrosting efficiency is improved, the problem that the indoor temperature is reduced greatly due to overlong defrosting time is avoided, and the user experience is improved.
Referring to fig. 2, a flowchart of an embodiment of another air conditioner control method according to an embodiment of the present application is provided. The flow shown in fig. 2 describes how to control the indoor fan operation based on the initial ambient temperature and the real-time ambient temperature of the space on the basis of the flow shown in fig. 1 described above. As shown in fig. 2, the process may include the steps of:
s201, determining a corresponding indoor temperature change rate based on the initial ambient temperature and the real-time ambient temperature.
In the embodiment of the present application, based on the initial ambient temperature and the real-time ambient temperature, determining the corresponding indoor temperature change rate may include: determining a first moment for acquiring the initial environmental temperature and determining a second moment for acquiring the real-time environmental temperature; determining a corresponding temperature difference based on the initial ambient temperature and the real-time ambient temperature, and determining a corresponding interval duration based on the first time and the second time; and taking the ratio of the temperature difference to the interval duration as the indoor temperature change rate.
For example, when the initial indoor environment temperature before defrosting is tc, the real-time environment temperature is tin, and the interval duration is T, the indoor temperature change rate v= |tin-tc|/T is obtained.
S202, closing the indoor fan under the condition that the indoor temperature change rate is greater than or equal to a first change rate threshold value.
And S203, controlling the indoor fan to operate based on the indoor temperature change rate and the real-time environment temperature under the condition that the indoor temperature change rate is smaller than a first change rate threshold.
S202 and S203 are collectively described below:
In the embodiment of the application, under the condition that the indoor temperature change rate is greater than or equal to the first change rate threshold, the indoor fan is turned off because the indoor temperature change is large due to the operation of the indoor fan, and bad user experience is easy to cause.
In the case that the indoor temperature change rate is smaller than the first change rate threshold value, it means that although the indoor temperature change is large due to the operation of the indoor fan, the user experience is not greatly affected, and at this time, the operation of the indoor fan can be further controlled according to the indoor temperature change rate and the real-time environmental temperature.
As one possible implementation manner, the specific implementation manner of controlling the operation of the indoor fan based on the indoor temperature change rate and the real-time environment temperature may include: and under the condition that the indoor temperature change rate is smaller than or equal to a second change rate threshold value, determining a target rotating speed based on the real-time environment temperature, and controlling the indoor fan to operate according to the target rotating speed, wherein the second change rate threshold value is smaller than the first change rate threshold value, and under the condition that the indoor temperature change rate is larger than the second change rate threshold value, determining whether to close the indoor fan based on the real-time environment temperature.
The second change rate threshold value is smaller than the first change rate threshold value, and when the indoor temperature change rate is smaller than or equal to the second change rate threshold value, the condition that the indoor temperature change is small due to the fact that the indoor fan is operated means that the indoor fan can be continuously operated, and the rotating speed of the operation of the indoor fan can be corrected according to the real-time environment temperature.
Specifically, determining the target rotational speed based on the real-time ambient temperature includes: and determining the first preset rotating speed as the target rotating speed when the real-time environment temperature is smaller than or equal to a first temperature threshold value, determining the second preset rotating speed as the target rotating speed when the real-time environment temperature is larger than the first temperature threshold value and smaller than a second temperature threshold value, and determining the third preset rotating speed as the target rotating speed when the real-time environment temperature is larger than or equal to the second temperature threshold value, wherein the first preset rotating speed is smaller than the second preset rotating speed and the second preset rotating speed is smaller than the third preset rotating speed.
Through this scheme, can be according to the rotational speed of real-time ambient temperature correction indoor fan, that is, the higher then rotational speed of implementation ambient temperature. Therefore, the rotating speed of the indoor fan can be increased under the condition of higher indoor environment temperature, heat exchange of the indoor coil is further accelerated, defrosting time is reduced, and defrosting efficiency is improved. And under the condition of lower indoor environment temperature, the fan operates at a lower rotating speed, so that the influence of the indoor fan on the indoor environment temperature is reduced.
And in the case where the indoor temperature change rate is greater than the second change rate threshold value, although the indoor temperature change is large due to the operation of the indoor fan, it may be determined whether the operation can be continued at the lowest rotational speed according to the real-time ambient temperature.
Specifically, determining whether to turn off the indoor fan based on the real-time ambient temperature may include: and closing the indoor fan under the condition that the real-time environment temperature is smaller than a second temperature threshold value, and operating the indoor fan according to a first preset rotating speed under the condition that the real-time environment temperature is larger than or equal to the second temperature threshold value.
Through this scheme, at the circumstances that leads to indoor temperature change great because the indoor fan of operation, and, real-time ambient temperature is less, in order to avoid further cooling down indoor temperature because of the indoor fan of operation, close indoor fan. And under the condition that the real-time environment temperature is greater than or equal to the second temperature threshold value, the indoor temperature is higher, and the indoor fan is operated at the lowest rotating speed at the moment, so that the indoor temperature can be prevented from being quickly reduced.
That is, after the indoor fan is started, the indoor fan operation may be controlled based on the following operation control table (i.e., table 1).
Table 1:
| v≤v2 | v2＜v＜v1 | v1≤v | |
| tin≤t3 | the indoor fan operates at the lowest rotating speed R | Closing the indoor fan | Closing the indoor fan |
| t3＜tin＜t4 | The indoor fan runs at the rotating speed of R+50rpm | Closing the indoor fan | Closing the indoor fan |
| t4≤tin | The indoor fan runs at the rotating speed of R+100rpm | The indoor fan operates at a rotating speed R | Closing the indoor fan |
Wherein V is the indoor temperature change rate; v1 is a first rate of change threshold; v2, a second rate of change threshold; tin is the real-time ambient temperature; t3, a first temperature threshold; t4, is a second temperature threshold.
In practical applications, the first rate threshold may be any value in the temperature rate interval [0.3,0.6], and the second rate threshold may be any value in the temperature rate interval [0,0.3 ].
Through the flow shown in fig. 2, the operation or the closing of the indoor fan is controlled according to the indoor temperature change rate and the real-time environmental temperature, so that the rotating speed of the indoor fan can be corrected at a larger rotating speed when the influence of the indoor fan on the indoor temperature is smaller due to the operation of the indoor fan, the heat exchange of the indoor coil is further accelerated, the defrosting time is reduced, and the defrosting efficiency is improved. And when the influence of the running indoor fan on the indoor temperature is large, the running indoor fan is operated or turned off at a lower rotating speed, so that the influence of the running indoor fan on the indoor environment temperature is reduced.
