Embodiments of the present application will be described below with reference to the accompanying drawings.
In one possible embodiment of the present application, a method for controlling mildew resistance of an air conditioner is provided, which can be applied to a control module of the air conditioner. Fig. 1 is a flowchart of a method for controlling mildew resistance of an air conditioner according to an embodiment of the present application, as shown in fig. 1, the method includes:
s101, the air conditioner reaches a preset mildew-proof control condition:
in the refrigeration mode or the dehumidification mode, the temperature of the evaporator coil is low, and condensed water is easy to generate, so that the air conditioner can reach preset mildew-proof control conditions if the air conditioner triggers the following conditions at the same time:
the air conditioner is in a refrigeration or dehumidification mode;
the current running time length of the air conditioner compressor is larger than a first time length threshold value;
and receiving a shutdown instruction of a user.
After the air conditioner is continuously operated for a certain period of time, a certain amount of condensed water may be accumulated on the surface and reach the extent that drying is required. In this embodiment, the first time threshold may be 20 minutes, that is, when the first time threshold is 20 minutes, the air conditioner is longer than 20 minutes when the air conditioner compressor is operated for this time, and when a shutdown instruction of a user is received in a cooling or dehumidifying mode, the air conditioner reaches a preset mildew-proof control condition. The first time length threshold value can be determined according to the actual conditions of the air conditioner model, the installation environment and the like, and the specific numerical value of the first time length threshold value is not limited.
S102, controlling the air conditioner to execute residual cooling operation, wherein the residual cooling operation comprises the following steps: after the air conditioner compressor is controlled to stop running, controlling the fan of the air conditioner indoor unit to run and adjusting the air deflector of the air conditioner indoor unit to a preset opening;
when the air conditioner just finishes a refrigeration or dehumidification mode, a certain amount of residual cold air, namely residual cold, is accumulated in the air conditioner indoor unit, the residual cold needs to be blown away to facilitate subsequent heating and drying of the evaporator, and meanwhile, the residual cold can also play a certain drying role on condensate water on the surface of the evaporator.
In this embodiment, after the air conditioner compressor is controlled to stop running, the fan of the air conditioner indoor unit is controlled to run, so that the effect of blowing off residual cold and drying condensed water on the surface of the evaporator can be achieved. The purpose of adjusting the air deflector of the indoor unit of the air conditioner to the preset opening degree is to blow out the residual cold. Optionally, adjusting the air deflector of the air conditioner indoor unit to a preset opening degree is adjusting the air deflector of the air conditioner indoor unit to a position with maximum air output. When the air deflector is at the position with the maximum air output, the residual cold in the indoor unit can be blown out more quickly. Usually, the maximum position of the air outlet quantity of the air deflector is an included angle of 45 degrees between the air deflector and the air outlet surface of the indoor unit.
S103, after a first preset time length is reached, controlling the air conditioner to execute a drying operation, wherein the drying operation comprises the following steps: and controlling the air deflector of the air conditioner indoor unit to be closed, controlling the air conditioner compressor to run, and regulating the rotating speeds of the air conditioner indoor unit fan and the air conditioner outdoor unit fan so as to control the air conditioner compressor to raise the temperature of the air conditioner evaporator coil to the target temperature.
After the air conditioner performs the residual cooling operation for a first preset period of time, the residual cooling inside the indoor unit is blown out at the moment, so as to solve the problem that condensate water on the surface of the evaporator cannot be dried by only the residual cooling in the prior art.
In the process of performing a drying operation of the air conditioner, the compressor is first controlled to operate, and the exhaust temperature of the compressor is raised. The outdoor air is introduced by the outdoor fan, so that the heat pump system of the air conditioner can absorb heat from the outdoor air and transfer the absorbed heat to the exhaust of the compressor, and the rotation speed of the outdoor fan influences the introduced amount of the outdoor air in unit time of the air conditioner, thereby influencing the exhaust temperature of the compressor. In this embodiment, the compressor discharge temperature is adjusted by adjusting the rotational speed of the outdoor fan.
Further, the warmed compressor discharge air enters the evaporator coil, thereby raising the evaporator coil temperature. The evaporator coil temperature may not be maintained at the target temperature and the evaporator surface temperature may be adjusted by the principle of air cooling by adjusting the rotational speed of the indoor unit fan. The air deflector is closed, so that on one hand, the indoor unit can form a closed environment, the operation of the fan of the indoor unit enables heat emitted by the evaporator coil to circulate in the indoor unit, the surface of the evaporator can be dried, and other areas possibly generating condensed water in the indoor unit can be dried; on the other hand, the fan of the indoor unit can be prevented from blowing hot air into a room, and the use experience of a user is prevented from being influenced.
In this embodiment, the target temperature may be stored in the storage module of the air conditioner in advance, so that the control module of the air conditioner may read the target temperature from the storage module.
In this embodiment, optionally, adjusting the rotational speeds of the air conditioner indoor unit fan and the air conditioner outdoor unit fan to control the air conditioner compressor to raise the temperature of the air conditioner evaporator coil to the target temperature includes:
controlling an air conditioner to detect the surface temperature of the evaporator, and calculating the difference value between the surface temperature of the evaporator and the target temperature;
taking the difference value between the surface temperature of the evaporator and the target temperature as the input of a first PID control algorithm, wherein the output of the first PID control algorithm is the rotating speed of the fan of the outdoor unit; and taking the difference value between the surface temperature of the evaporator and the target temperature as the input of a second PID control algorithm, wherein the output of the second PID control algorithm is the rotating speed of the fan of the indoor unit.
The evaporator surface temperature can be controlled more precisely by the PID control algorithm, and can be detected by a temperature sensor provided to the evaporator surface.
In this embodiment, optionally, adjusting the rotational speeds of the air conditioner indoor unit fan and the air conditioner outdoor unit fan to control the air conditioner compressor to raise the temperature of the air conditioner evaporator coil to the target temperature includes:
the rotation speed of the fan of the air conditioner indoor unit is controlled to be reduced, and the rotation speed of the fan of the air conditioner outdoor unit is controlled to be increased.
Specifically, the outdoor unit fan rotation speed and the indoor unit fan rotation speed corresponding to the target temperature may be stored in the storage module of the air conditioner in advance, so that the outdoor unit fan rotation speed and the indoor unit fan rotation speed may be adjusted. The compressor starts to run in the drying operation stage, so that the rotation speed of the outdoor fan is increased, and the rotation speed of the indoor fan is lower than that of the indoor fan in the residual cooling operation stage to avoid excessive reduction of the surface temperature of the evaporator by the indoor fan.
In this embodiment, optionally, when the air conditioner performs the residual cooling operation or the drying operation, if the mildew-proof mode exit instruction of the user is received, the air conditioner is controlled to exit the residual cooling operation or the drying operation.
The technical effects of this embodiment are: the application solves the technical problem that the condensed water on the surface of the evaporator cannot be completely dried by only blowing residual cold in the prior art by a mode of blowing residual cold and then drying. Further, in the present application, the compressor is turned on after the residual cool is blown, and the temperature of the evaporator coil is raised by adjusting the rotation speed of the outdoor fan to raise the temperature of the compressor discharge air which enters the evaporator. After the indoor unit air deflector is closed, the temperature of the evaporator coil can be controlled by adjusting the rotating speed of the indoor unit fan, so that the temperature of the evaporator coil is not too high, heat emitted by the evaporator coil can be circulated in the closed air conditioner, the condensate water in the indoor unit can be better dried, mold breeding is prevented, and the closed air deflector can also prevent the indoor unit fan from blowing hot air heated by the evaporator coil into a room.
In one possible embodiment of the present application, another method for controlling mildew resistance of an air conditioner is provided, and fig. 2 is a flowchart of another method for controlling mildew resistance of an air conditioner according to an embodiment of the present application, as shown in fig. 2, the method includes:
s201, controlling the rotation speed of the fan of the indoor unit of the air conditioner to be reduced to the rotation speed of the first indoor fan, and simultaneously controlling the rotation speed of the fan of the outdoor unit of the air conditioner to be increased to the rotation speed of the first outdoor fan so as to control the compressor to increase the temperature of the coil pipe of the evaporator to a first target temperature and keep the temperature for a second preset time period;
s202, controlling the rotation speed of the air conditioner indoor unit fan to be reduced from the rotation speed of the first indoor fan to the rotation speed of the second indoor fan, and simultaneously controlling the rotation speed of the air conditioner outdoor unit fan to be increased from the rotation speed of the first outdoor fan to the rotation speed of the second outdoor fan so as to control the compressor to increase the temperature of the evaporator coil to the second target temperature and keep the third preset time period.
In steps S201 and S202, the air deflectors of the indoor units are all in the closed positions.
In step S202, the second target temperature is higher than the first target temperature, that is, in this embodiment, the air conditioner performs the low-temperature drying first and then the high-temperature drying when performing the drying operation.
The technical effects of this embodiment are: firstly, low-temperature drying is carried out to remove a large amount of water in the indoor unit, so that a large amount of water vapor is avoided being generated in the high-temperature drying stage; and inactivating the mould inside the indoor unit through high temperature during high temperature drying.
In this embodiment, the first target temperature may be 37 ℃, and the second target temperature may be 40 ℃, which is not limited to specific values of the first target temperature and the second target temperature.
