Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the present invention and should not be construed as limiting the present application.
An air conditioner and a control method and apparatus thereof according to an embodiment of the present application are described below with reference to the accompanying drawings.
It should be noted that, in this embodiment, a heating assembly is disposed in the air conditioner, and the heating assembly is used for heating air entering the room through the air outlet duct in the air conditioner, and the arrangement position of the heating assembly may be determined according to actual situations, and is not limited herein.
Fig. 1 is a flowchart illustrating a method for controlling an air conditioner according to an embodiment of the present disclosure. As shown in fig. 1, the method for controlling an air conditioner according to the embodiment of the present application specifically includes the following steps:
and S101, controlling the air conditioner to operate in a heating mode.
Generally, the air conditioner may have a possibility of frost formation when the air conditioner is in the heating mode, and therefore, in the present embodiment, the air conditioner needs to be controlled to operate in the heating mode. For example, after receiving an instruction sent by a relevant person to control the air conditioner to operate in the heating mode, the air conditioner may be controlled to operate in the heating mode.
S102, recognizing that the air conditioner meets the defrosting condition, controlling the air conditioner to run in a refrigeration mode, and controlling a heating assembly in the air conditioner to be started.
Specifically, when the air conditioner is recognized to meet the defrosting condition, the air conditioner is controlled to operate in a refrigeration mode to defrost; meanwhile, the heating assembly is controlled to be opened to heat air entering the room through an air outlet duct in the air conditioner, so that the temperature of the air entering the room is increased, the fluctuation of the indoor temperature of the air conditioner in the defrosting process is reduced, and the comfort level of the indoor environment is improved. In addition, in the defrosting process, the indoor temperature is kept to be higher, the refrigerant in the indoor heat exchanger of the air conditioner can absorb more heat, the temperature of the refrigerant entering the compressor through the indoor heat exchanger is increased, the exhaust temperature of the compressor is further increased, the defrosting speed is increased, and the influence of defrosting on the indoor temperature is reduced.
In some embodiments, the fan in the air conditioner can be controlled according to the arrangement position of the heating assembly, so that the control accuracy is improved. As shown in fig. 2, the method comprises the following steps:
s201, acquiring the arrangement position of the heating assembly.
Specifically, the arrangement position of the heating component may be stored in advance in the air conditioner, and when the arrangement position of the heating component needs to be acquired, the arrangement position of the heating component may be acquired by querying the prestored parameters.
Alternatively, the arrangement position of the heating component may also be determined according to the model of the air conditioner. For example, the arrangement position of the heating component of each type of air conditioner is often fixed, so that after the type of the air conditioner is obtained, the arrangement position of the heating component can be determined according to the type of the air conditioner.
And S202, controlling a fan in the air conditioner according to the arrangement position.
Specifically, determine heating element's the position of arranging, just can control the fan in the air conditioner according to heating element's the position of arranging to promote the precision of control.
As a possible implementation manner, when the heating component is arranged at the air outlet of the air conditioner, the air temperature at the air outlet is less affected by the operation of the fans, but in order to ensure that the air in the air outlet duct of the air conditioner normally flows, at least one fan may be controlled to be in an open state, and the other fans may be in a closed state or in an open state. That is, when it is detected and determined that the arrangement position is the air outlet of the air conditioner, the at least one fan is controlled to be in the on state.
As another possible implementation, when the heating component is not disposed at the air outlet of the air conditioner, the operation of the fan will affect the air temperature at the air outlet. For example, when there are two fans, and the heating element corresponds to one of the fans, and the other fan does not have a corresponding heating element, at this time, if both fans are in an on state, the air passing through one of the fans will be heated, and the air passing through the other fan will not be heated, so that the air entering the room from the air conditioner has both heated air and unheated air; further, when heated air is mixed with unheated air, the temperature in the room still fluctuates greatly, and it is difficult to achieve the desired effect. Therefore, in the present embodiment, when it is detected that the arrangement position is not at the air outlet of the air conditioner, the fan corresponding to the heating element is controlled to be in the on state, and the fan not corresponding to the heating element is controlled to be in the off state, so as to reduce the fluctuation of the indoor temperature, thereby achieving the desired effect.
For example, as shown in fig. 3, the fans include a first fan 13 and a second fan 14, wherein the heating element 11 is disposed between the first fan 13 and the evaporator 12, and at this time, the first fan 13 is controlled to be in an on state, and the second fan 14 is controlled to be in an off state. As shown in fig. 4, the fans include a first fan 13 and a second fan 14, wherein if the heating assembly 11 is disposed between the second fan 14 and the evaporator 12, the second fan 14 is controlled to be in an on state at this time, and the first fan 13 is controlled to be in an off state.
In some embodiments, when the air flow rate is high, the heating assembly will have difficulty in sufficiently heating the air flowing through the heating assembly, which causes the temperature of the air entering the room to be low, and the temperature in the room will still fluctuate greatly, which makes it difficult to achieve the desired effect. Therefore, when the fan is controlled to be in the opening state, the rotating speed of the fan can be controlled to adjust the flow rate of the air. As shown in fig. 5, the method comprises the following steps:
s301, obtaining the running gear of the fan in the starting state at present.
Specifically, the preset operation gear of the fan in the air conditioner during defrosting can be queried to determine the operation gear of the fan currently in the on state.
And S302, controlling the fan in the opening state to operate at the highest speed limit lower than the rotating speed of the fan corresponding to the operating gear.
Specifically, after the operation gear of the fan currently in the on state is obtained, the highest speed limit of the fan at the moment can be determined according to the mapping relation between the operation gear and the highest speed limit of the rotating speed of the fan corresponding to the operation gear. Further, in order to reduce the flow speed of the air, the fan which is in the opening state at present is controlled to operate at the rotating speed lower than the highest speed limit.
In some embodiments, whether the air conditioner satisfies the defrosting condition may be determined according to the temperature of the outdoor heat exchanger. As shown in fig. 6, the method comprises the following steps:
s401, acquiring the temperature of an outdoor heat exchanger in the air conditioner.
Generally, the temperature of the outdoor heat exchanger may be acquired using a temperature sensor provided on the outdoor heat exchanger.
S402, identifying the duration that the temperature of the outdoor heat exchanger reaches the preset temperature lasts for the preset duration, and determining that the air conditioner meets the defrosting condition.
Specifically, when the temperature of the outdoor heat exchanger reaches the preset temperature, it is indicated that the outdoor heat exchanger starts to frost, and when the time length that the temperature of the outdoor heat exchanger reaches the preset temperature lasts for the preset time length, the frosting degree on the outdoor heat exchanger is high at the moment, and defrosting is needed at the moment, namely, the defrosting condition is met. Optionally, the preset temperature is a temperature of less than-4 ℃.
Further, in the defrosting process, when the temperature of the outdoor heat exchanger is detected to be increased to the preset temperature, it can be determined that the defrosting of the outdoor heat exchanger is finished, at this time, the air conditioner can be controlled to exit the defrosting mode, and for example, the air conditioner is controlled to be operated from the cooling mode to the heating mode.
It should be noted that, in the present embodiment, the rotation direction of the fan is a forward rotation when the fan operates, that is, the fan promotes the air in the air outlet channel to flow into the room.
To sum up, the technical solution in the embodiment of the present application at least has the following technical effects or advantages:
1. in the defrosting process of the air conditioner, the heating assembly is controlled to be started to heat air entering the room from the air outlet duct of the air conditioner, so that the temperature of the air entering the room is increased, the fluctuation of the indoor temperature of the air conditioner in the defrosting process is reduced, and the comfort level of the indoor environment is improved.
2. In the defrosting process, the heating assembly is started, so that the indoor temperature can be kept at a higher temperature, the refrigerant in the indoor heat exchanger of the air conditioner can absorb more heat, the temperature of the refrigerant entering the compressor through the indoor heat exchanger is increased, the exhaust temperature of the compressor is increased, the defrosting speed is increased, and the influence of defrosting on the indoor temperature is reduced.
3. The fan in the air conditioner is controlled according to the arrangement position of the heating assembly, and the control accuracy is improved.
4. The fan in the starting state is controlled to operate at the highest speed limit lower than the rotating speed of the fan corresponding to the current operating gear, so that the heating assembly can fully heat air entering the room, and the stability of the indoor temperature is further ensured.
