Detailed Description
Embodiments of the present invention will be described in detail below, the embodiments described with reference to the drawings being illustrative, and the embodiments of the present invention will be described in detail below.
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.
The compressor compresses a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.
The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner can adjust the temperature of the indoor space throughout the cycle.
The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.
The indoor heat exchanger and the outdoor heat exchanger serve as a condenser or an evaporator. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater in a heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler in a cooling mode.
An air conditioner according to some embodiments of the present application includes an air conditioner indoor unit installed in an indoor space. The indoor unit, i.e., the indoor unit, is connected to an outdoor unit, i.e., the outdoor unit, installed in an outdoor space through a pipe. The outdoor unit of the air conditioner may be provided with a compressor, an outdoor heat exchanger, an outdoor fan, an expander, and the like for a refrigeration cycle, and the indoor unit of the air conditioner may be provided with an indoor heat exchanger and an indoor fan.
An air conditioner control method according to an embodiment of a first aspect of the present invention is described below with reference to fig. 1 to 4.
As shown in fig. 1, an air conditioner control method according to an embodiment of a first aspect of the present invention includes the steps of:
a detection signal value is obtained, the detection signal value including at least one of an indoor ambient temperature, an outlet temperature of the compressor, and a current of the compressor. The indoor environment temperature and the outlet temperature of the compressor can be detected by the temperature sensor, and the current of the compressor can be detected by the current sensor.
And when the detection signal value reaches a first preset threshold value, reducing the rotating speed of the inner fan and increasing the rotating speed of the outer fan. In this step, when the detection signal values are different, the first predetermined threshold value may be different.
For example, in the examples of fig. 2 to 4, when the detection signal value is the indoor ambient temperature, the first predetermined threshold may be a first indoor ambient temperature threshold, and when the detected indoor ambient temperature reaches the first indoor ambient temperature threshold, it indicates that the indoor ambient temperature is too high and the current of the air conditioner is too large, and by reducing the rotation speed of the inner fan and increasing the rotation speed of the outer fan, the indoor heat exchange speed may be reduced, so that the heat dissipation condition of the compressor may be improved, and the current in the air conditioner may be effectively reduced. Alternatively, the first indoor ambient temperature threshold may be 35 ℃ to 40 ℃ (inclusive). But is not limited thereto.
When the detection signal value is the outlet temperature of the compressor, the first predetermined threshold may be a first outlet temperature threshold, for example, the outlet temperature of the compressor may be obtained by detecting the temperature of the outside coil. Wherein the outside coil is connected between an air conditioner, such as a mobile air conditioner, and an outdoor area. When the detected outlet temperature of the compressor reaches the first outlet temperature threshold value, the fact that the outlet temperature of the compressor is too high and the current of the air conditioner is too large is shown, the indoor heat exchange speed can be reduced by reducing the rotating speed of the inner fan and increasing the rotating speed of the outer fan, so that the heat dissipation condition of the compressor can be improved, and the current in the air conditioner is effectively reduced. It should be noted that, when the air conditioner is a mobile air conditioner, the inner fan is an upper fan of the mobile air conditioner, and the outer fan is a lower fan of the mobile air conditioner.
When the detection signal value is the current of the compressor, the first preset threshold value can be a first current threshold value, when the detected current of the compressor reaches the first current threshold value, the current value of the compressor is over large, and the indoor heat exchange speed can be reduced by reducing the rotating speed of the inner fan and increasing the rotating speed of the outer fan, so that the heat dissipation condition of the compressor can be improved, and the current flowing in the compressor can be effectively reduced.
According to the air conditioner control method provided by the embodiment of the invention, the indoor heat exchange speed can be reduced by acquiring the detection signal value of at least one of the indoor environment temperature, the outlet temperature of the compressor and the current of the compressor, and reducing the rotating speed of the inner fan and increasing the rotating speed of the outer fan when the detection signal value reaches the first preset threshold value, so that the heat dissipation condition of the compressor can be improved, the current in the air conditioner is effectively reduced, the current in the air conditioner is prevented from exceeding the maximum current value specified by the plug, and the use comfort and safety of a user are improved.
In some embodiments of the present invention, referring to fig. 2 to 4, when the detection signal value is lower than a second predetermined threshold value, the rotation speed of the inner fan is increased, and the rotation speed of the outer fan is controlled to be kept unchanged, and the second temperature threshold value is smaller than the first temperature threshold value. Wherein the second predetermined threshold may be different when the detection signal values are different.
For example, in conjunction with fig. 2-4, when the detection signal value is an indoor ambient temperature, the second predetermined threshold may be a second indoor ambient temperature threshold; when the detection signal value is the outlet temperature of the compressor, the second predetermined threshold value may be a second outlet temperature threshold value; when the detection signal value is the current of the compressor, the second predetermined threshold may be a second current threshold. From this, when the detected signal value is less than corresponding second predetermined threshold value, explain the electric current decline in the air conditioner, through the rotational speed that improves interior fan this moment, can improve indoor air output to can effectively adjust indoor ambient temperature, promote user experience, moreover, the rotational speed through controlling outer fan remains unchanged, makes the compressor can realize better radiating effect, thereby can further reduce the electric current in the air conditioner, guarantees user's safety in utilization.
Optionally, when the detection signal value is lower than a second predetermined threshold value, the rotating speed of the inner fan is increased by at least one gear. For example, the inner fan may include four gears of zero gear, low gear, middle gear and high gear, and when the detection signal value reaches a first predetermined threshold value, the rotation speed of the inner fan may be reduced by at least one gear, for example, from high gear to middle gear or low gear. When the detection signal value is lower than a second preset threshold value, the rotating speed of the inner fan can be increased by at least one gear from the previous middle gear or low gear. Therefore, the rotating speed of the inner fan is increased simply and is convenient to control, and the accuracy of increasing the rotating speed of the inner fan can be improved while the energy consumption is reduced.
In some embodiments of the present invention, with reference to fig. 2 to 4, when the duration of the detection signal value being lower than the second predetermined threshold reaches the first predetermined time, the inner fan is controlled to return to the set rotation speed, and the outer fan returns to the original rotation speed. For example, a temperature sensor for detecting an indoor ambient temperature, a temperature sensor for detecting an outlet temperature of the compressor, and a current sensor for detecting a current of the compressor may be electrically connected to the MCU, and when a duration of a detection signal value lower than a second predetermined threshold reaches a first predetermined time, the MCU may control the inner fan to return to a set rotation speed and the outer fan to return to an original rotation speed.
The MCU is a Microcontroller Unit (Microcontroller Unit), also called a Single Chip Microcomputer (CPU), or a Single Chip Microcomputer (MCU), which properly reduces the frequency and specification of a Central Processing Unit (CPU), and integrates peripheral interfaces such as a memory (memory), a counter (Timer), a USB, an a/D converter, a UART, a PLC, a DMA, and the like, and even an LCD driving circuit on a Single Chip, thereby forming a Chip-level computer, which performs different combination control for different applications.
Therefore, when the duration time that the detection signal value is lower than the corresponding second preset threshold reaches the first preset time, the current in the air conditioner is reduced and tends to a stable state, the air outlet speed of the inner fan can be recovered to the air outlet speed set by the user by controlling the inner fan to recover to the set rotating speed, and the use comfort of the user can be improved on the basis of ensuring the use safety of the user. Moreover, the energy consumption of the air conditioner can be reduced by restoring the external fan to the original rotating speed, thereby reducing the cost.
In some embodiments of the present invention, as shown in fig. 2 to 4, when the detection signal value reaches a third predetermined threshold value, the rotation speed of the inner fan is continuously reduced, and the rotation speed of the outer fan is controlled to be kept unchanged, and the third predetermined threshold value is greater than the first predetermined threshold value. Wherein the third predetermined threshold may be different when the detection signal values are different.
For example, referring to fig. 2 to fig. 4, when the detection signal value is the indoor ambient temperature, the third predetermined threshold may be a third indoor ambient temperature threshold, and when the indoor ambient temperature reaches the third indoor ambient temperature threshold, it indicates that the indoor ambient temperature is increasing and too high, and the current in the air conditioner is too large; when the detection signal value is the outlet temperature of the compressor, the third predetermined threshold value may be a third outlet temperature threshold value, and when the outlet temperature of the compressor reaches the third outlet temperature threshold value, it indicates that the outlet temperature of the compressor is in an increasing trend and is too high, and the current in the air conditioner is too large; the third predetermined threshold may be a third current threshold when the detection signal value is the current of the compressor, and when the current of the compressor reaches the third current threshold, it indicates that the current in the compressor is too large. Therefore, the rotating speed of the inner fan is continuously reduced, the outer fan still maintains high rotating speed operation, indoor heat exchange speed can be further reduced, the heat dissipation condition of the compressor is further improved, current in the air conditioner is reduced, the current in the air conditioner is prevented from exceeding the maximum current value specified by the plug, and the use safety of a user is guaranteed.
Further, when the detection signal value reaches a third preset threshold value, the rotating speed of the inner fan is reduced by at least one gear. For example, when the detection signal value reaches a first predetermined threshold value, the rotation speed of the inner fan may be reduced by at least one gear, for example, from a high gear to a medium gear or a low gear. When the detection signal value reaches a third preset threshold value, the rotating speed of the inner fan can be continuously reduced to a low gear or a zero gear from a previous middle gear or a previous low gear. Therefore, the rotating speed of the inner fan is reduced simply, the control is convenient, and the accuracy of reducing the rotating speed of the inner fan can be improved while the energy consumption is reduced.

For example, the air conditioner may be a mobile air conditioner or a window type air conditioner, etc. Of course, the air conditioner may be other types of air conditioners, and is not limited to a mobile air conditioner or a window type air conditioner.
According to the air conditioner, such as a mobile air conditioner or a window type air conditioner, by adopting the air conditioner control method, the indoor heat exchange speed can be reduced, so that the heat dissipation condition of the compressor can be improved, the current in the air conditioner can be effectively reduced, the current in the air conditioner is prevented from exceeding the maximum current value specified by the plug, and the use comfort and the safety of a user are improved.
