For example, when it is required to sterilize the indoor unit side of the air conditioner, the air conditioner heating operation may be controlled to place the indoor heat exchanger in a condensing state when entering the first operation mode. If the air conditioner is in refrigerating operation before entering the first operation mode, the four-way valve can be controlled to switch the state, so that the indoor heat exchanger is switched into the condenser.
In the first operation mode, the indoor heat exchanger is controlled to enter a condensation state, and the refrigerant is in a high-temperature heat-release state in the indoor heat exchanger. If different indoor heat exchangers in the air conditioner need to be disinfected, the indoor heat exchangers needing to be disinfected can be respectively or simultaneously switched into condensers through the matching adjustment of the four-way valve, the throttling device and the like.
And when the air conditioner enters the first running mode, resetting the timer to 0, and controlling the timer to start timing.
Step S20, controlling an electronic expansion valve of the air conditioner to adjust the opening degree so that the temperature of the indoor unit side of the air conditioner is greater than or equal to a first set temperature;
the electronic expansion valve is a throttling device which is arranged in a refrigerant circulation loop of the air conditioner and can be controlled by an electric control method, and is used for adjusting the refrigerant flow in an indoor heat exchanger of the air conditioner (particularly a heat exchanger needing to be disinfected). The temperature of the indoor unit side is specifically the temperature detected by a temperature sensor arranged at a position such as an indoor heat exchanger coil, a position close to the indoor unit coil, a position at an air outlet of the indoor unit, a position in an air duct of the indoor unit, and the like.
The first set temperature is specifically a preset minimum threshold value of the temperature of the indoor unit side of the air conditioner, where the virus killing rate reaches a first threshold value (which can be set according to specific virus killing requirements). Based on the first set temperature, the temperature of the indoor unit side is greater than or equal to the first set temperature, the killing rate of the viruses in the indoor unit side of the air conditioner at least reaches a first threshold value, and the viruses in the indoor unit side of the air conditioner can be effectively killed; the temperature of the indoor unit side of the air conditioner is lower than the first set temperature, and the virus killing rate of the indoor unit side of the air conditioner cannot reach the first threshold value, so that the virus of the indoor unit side of the air conditioner cannot be effectively killed. The first set temperature may be specifically set according to the type of virus to be killed, the actual use scene of the air conditioner (hospital, home), and the like. In this embodiment, the first set temperature may be selected to be 56 ℃.
Specifically, in the refrigerant circulation loop, the electronic expansion valve has different regulation and control characteristics for the indoor heat exchanger according to different connection relations between the electronic expansion valve and the indoor heat exchanger. For example, in the present embodiment, in the refrigerant circulation circuit, the compressor, the indoor heat exchanger, the electronic expansion valve, and the outdoor heat exchanger are sequentially communicated, and the electronic expansion valve is a throttle device provided at an outlet of the indoor heat exchanger (in a condensed state). The opening degree of the electronic expansion valve is reduced, the amount of refrigerants in the indoor heat exchanger is increased, and the temperature of the indoor unit side can be increased; the increase of the opening of the electronic expansion valve reduces the amount of refrigerant in the indoor heat exchanger, and the temperature of the indoor unit can be lowered. Based on this, the opening degree of the electronic expansion valve is controlled to be reduced according to a certain rule, and the temperature of the indoor unit side of the air conditioner can be made to be higher than or equal to the first set temperature. In addition, the electronic expansion valve and the indoor heat exchanger can have other relative position relations, and the temperature of the indoor machine side can be increased or decreased by adjusting and controlling the opening degree in different directions based on different positions of the electronic expansion valve. For example, in another embodiment, the electronic expansion valve increases the opening degree to lower the temperature on the indoor unit side, and the electronic expansion valve decreases the opening degree to lower the temperature on the indoor unit side. Based on this, the opening degree of the electronic expansion valve is controlled to be increased according to a certain rule, and the temperature of the indoor unit side of the air conditioner can be made to be higher than or equal to the first set temperature.
The electronic expansion valve is adapted to different opening degree adjustment modes (increasing the opening degree, decreasing the opening degree, or maintaining the current opening degree) based on the difference of the current indoor unit side temperature. When the temperature of the indoor machine side of the air conditioner is lower than the first set temperature, the electronic expansion valve can be controlled to increase the temperature of the indoor machine side by increasing the opening degree or reducing the adjustment direction of the opening degree. When the temperature of the indoor unit side of the air conditioner is greater than or equal to a first set temperature, the electronic expansion valve can be controlled to maintain the current opening degree so as to maintain the temperature of the indoor unit side to be stable; in addition, the electronic expansion valve can be controlled to increase or decrease the opening degree according to different conditions of the air conditioner, so as to further increase or decrease the temperature of the indoor unit side according to actual requirements.
The opening degree of the electronic expansion valve may be adjusted according to a certain adjustment rule, except that the adjustment manner of the electronic expansion valve (increasing the opening degree or decreasing the opening degree or maintaining the current opening degree) is determined based on the relationship between the electronic expansion valve and the indoor-side temperature so as to increase the indoor-side temperature. The adjustment rule of the electronic expansion valve is various, and one of the adjustment rules can be selected arbitrarily, or one of the adjustment rules can be selected as the adjustment rule of the current opening degree of the electronic expansion valve according to the current operation state of the air conditioner. Specifically, controlling an electronic expansion valve of the air conditioner to adjust an opening according to a certain adjustment rule so that the temperature of the indoor unit side of the air conditioner is greater than or equal to a first set temperature specifically includes: acquiring a temperature difference between the current temperature of the indoor unit side of the air conditioner and the first set temperature as a first temperature difference; controlling the electronic expansion valve to adjust the opening according to the first temperature difference so that the temperature of the indoor unit side of the air conditioner is greater than or equal to a first set temperature; or, acquiring a first set amplitude to control the electronic expansion valve to adjust the opening degree, so that the temperature of the indoor unit side of the air conditioner is greater than or equal to a first set temperature; or controlling the electronic expansion valve to adjust the opening degree according to a first set coefficient and the current opening degree of the electronic expansion valve, so that the temperature of the indoor unit side of the air conditioner is greater than or equal to a first set temperature.
Specifically, after determining the adjustment mode (increasing the opening degree or decreasing the opening degree or maintaining the current opening degree) of the electronic expansion valve to increase the indoor unit side temperature, the adjustment range of the electronic expansion valve may be further determined so that the indoor unit side temperature may be greater than or equal to the first set temperature. The generation rule of the adjustment range of the electronic expansion valve is various, and one of the multiple generation rules may be selected arbitrarily, or one of the multiple generation rules may be selected as the generation rule of the adjustment range of the opening degree of the electronic expansion valve according to the current operation state of the air conditioner. Specifically, the generation rule of the adjustment range of the opening of the electronic expansion valve may include the following: rule 1, the adjustment range of the electronic expansion valve is determined according to preset adjustment parameters. For example, the first setting range may be directly used as the adjustment range of the electronic expansion valve. And 2, determining the adjustment range of the electronic expansion valve according to the current operation state of the air conditioner. For example, a temperature difference between a current temperature of the indoor unit side of the air conditioner and a temperature before a first set temperature is acquired as a first temperature difference, and an adjustment range of the electronic expansion valve is determined according to the first temperature difference. And 3, determining the adjustment range of the electronic expansion valve by combining preset adjustment parameters and the current running state of the air conditioner. For example, the adjustment range of the opening degree of the electronic expansion valve is determined according to a first setting coefficient and the current opening degree of the electronic expansion valve, specifically, the first setting coefficient may be a scaling coefficient smaller than 1, and the adjustment range of the opening degree of the electronic expansion valve is determined according to the product of the current opening degree and the first setting coefficient.
Step S20 may be repeatedly executed for a predetermined period of time (less than the first set time). Specifically, a first time point at which step S20 is first executed may be recorded, and if the length of the time interval between the current time point and the first time point does not exceed a predetermined time period, the opening degree of the electronic expansion valve may be continuously adjusted so that the indoor unit side temperature is equal to or higher than the first set temperature.
And step S30, controlling the air conditioner to exit the first running mode when the counted time reaches a first set time.
The first set time may be determined according to one or more factors, such as the type of virus to be killed, the usage scenario of the air conditioner, the magnitude of the first set temperature, the temperature rise rate of the indoor unit side temperature, and the indoor unit side temperature when entering the first operation mode.
After entering the first operation mode, the timing value in the timer can be read in real time, when the timing value reaches the first set time, the virus on the indoor unit side can be considered to be completely killed as required, and at the moment, the air conditioner is controlled to exit the first operation mode. Specifically, the air conditioner can be controlled to exit the first operation mode and stop; the air conditioner can also be controlled to enter other operation modes (for example, the operation mode of the air conditioner before entering the first operation mode) after exiting the first operation mode.
The method for controlling the air conditioner starts timing when the air conditioner enters a first operation mode, controls an electronic expansion valve of the air conditioner to adjust the opening degree so that the temperature of the indoor unit side of the air conditioner is greater than or equal to a first set temperature, and controls the air conditioner to exit the first operation mode when the timing reaches the first set time. In this way, under the first operation mode, control electronic expansion valve adjustment aperture makes indoor set side temperature can be more than or equal to first settlement temperature, adopts the temperature of high enough to kill the virus of indoor set side effectively to first operation mode lasts first settlement time, guarantees that air conditioner indoor set side disinfection is complete, thereby realizes the comprehensive disinfection of virus among the air conditioner indoor set, prevents that the air conditioner from adsorbing the virus and influencing indoor environment quality.

Further, determining a first generation rule of a first adjustment amplitude of the electronic expansion valve according to the first temperature difference comprises: determining a first opening adjustment value according to the first temperature difference, and acquiring a first correction value of the first opening adjustment value, wherein the first correction value is determined according to the current compressor frequency of the air conditioner and the rotating speed of an indoor fan; and determining a first adjusting amplitude of the electronic expansion valve according to the first opening degree adjusting value and the first correction value. Specifically, the first opening degree adjustment value increases as the first temperature difference increases. Different compressor frequencies and different indoor fan rotating speeds correspond to different first correction values, specifically, the larger the indoor fan rotating speed is, the larger the corresponding first correction value is, the smaller the compressor frequency is, and the larger the corresponding first correction value is, the relationship among the indoor fan rotating speed, the compressor frequency and the first correction value can be fitted in advance based on the influence of the indoor fan and the compressor on indoor side temperature regulation of the electronic expansion valve, and the first correction value corresponding to the current indoor fan rotating speed and the compressor frequency is determined based on the relationship fitted in advance. And taking the sum of the first correction value and the first opening degree adjusting value as a first adjusting amplitude of the opening degree of the electronic expansion valve.

After the first set range is obtained, the first set range may be used as a first adjustment range of the electronic expansion valve.

And after the first setting coefficient is obtained, taking the product of the first setting coefficient and the current opening degree of the electronic expansion valve as a first adjustment amplitude of the electronic expansion valve.
And step S204, controlling the electronic expansion valve of the air conditioner to adjust the opening according to the first adjustment range, so that the temperature of the indoor unit side of the air conditioner is greater than or equal to a first set temperature.
And controlling the electronic expansion valve to increase or decrease the determined first adjustment amplitude based on the regulation characteristic of the electronic expansion valve on the basis of the current opening degree so as to enable the temperature of the indoor unit side of the air conditioner to be greater than or equal to a first set temperature.

Further, based on the above embodiments, another embodiment of the air conditioner control method of the present application is provided. In another embodiment, referring to fig. 3, after the step S20, the method further includes:
step S21, judging whether the current temperature of the indoor machine side of the air conditioner is larger than or equal to the first set temperature;
specifically, when the duration of the execution of step S20 reaches the above-described predetermined period of time, step S21 may be executed.
If the current temperature of the indoor unit side of the air conditioner is lower than the first set temperature, step S22 is executed, and if the current temperature of the indoor unit side of the air conditioner reaches the first set temperature, components such as an electronic expansion valve, a fan, a compressor and the like in the air conditioner can be controlled to maintain the current state operation, the electronic expansion valve can also be controlled to continuously adjust the opening degree according to the original mode, the air conditioner can also be controlled according to the related mode in the following embodiments, and even other control modes can be provided according to actual requirements.
Step S22, judging whether the current opening degree of the electronic expansion valve is in a first opening degree range;
when the current opening degree of the electronic expansion valve is within the first opening degree range, performing step S23; and when the current opening degree of the electronic expansion valve is outside the first opening degree range, returning to the step of 20.
The first opening range may be set according to the actual condition of the air conditioner. The current opening degree is in the first opening degree range, and the condition that the normal operation of the air conditioner cannot be caused by the fact that the current opening degree of the electronic expansion valve is continuously adjusted can be considered; the current opening degree is out of the first opening degree range, and the normal operation of the air conditioner can be guaranteed even if the current opening degree of the electronic expansion valve is continuously adjusted. For example, when the indoor unit side temperature is increased by decreasing the opening degree of the electronic expansion valve, the first opening degree range may be divided based on the first opening degree threshold value, and an opening degree value equal to or smaller than the first opening degree threshold value may be divided into the first opening degree range.
And step S23, controlling the indoor fan to reduce the running speed or controlling the compressor to increase the running frequency or controlling the power of the electric auxiliary thermal module on the indoor machine side.
Specifically, the indoor fan may be controlled to reduce the operation speed or the compressor may be controlled to increase the operation frequency or the power of the electric auxiliary thermal module on the indoor unit side may be controlled according to preset parameters and/or the current operation state of the air conditioner. The reduction of the rotating speed of the indoor fan can reduce the heat of the indoor unit side of the air conditioner taken away when the air is blown to the outside of the air conditioner from the indoor unit side of the air conditioner, so that the heat carried by the refrigerant can be kept in the indoor heat exchanger, and the temperature of the indoor unit side of the air conditioner can be more than or equal to a first set temperature; the running frequency of the compressor is increased, so that the temperature of the refrigerant at the refrigerant outlet of the compressor can be increased, the temperature of the refrigerant flowing into the indoor heat exchanger is increased, and the temperature of the side of the indoor unit of the air conditioner can be higher than or equal to a first set temperature; the power of the electric auxiliary thermal module on the side of the indoor unit is improved, so that the heat productivity of the electric auxiliary thermal module is improved, and the temperature of the side of the indoor unit can be greater than or equal to the first set temperature.
In order to ensure the accuracy of temperature regulation of the indoor unit side by matching the fan, the compressor and the electronic expansion valve, the regulation parameters of the fan can be determined according to the current temperature of the indoor unit side, the current opening degree of the electronic expansion valve and the frequency of the compressor, and the indoor fan is controlled to reduce the running speed according to the determined regulation parameters; or, determining the adjustment parameter of the compressor according to the current temperature of the indoor unit side, the current opening degree of the electronic expansion valve and the rotating speed of the indoor fan, and controlling the compressor to improve the running frequency according to the determined adjustment parameter. In addition, the step of controlling the power-up of the indoor unit side electric auxiliary thermal module includes: when the electric auxiliary thermal module on the indoor unit side is in a closed state currently, the electric auxiliary thermal module is controlled to be started and operated at a power not lower than a threshold value; when the electric auxiliary thermal module on the indoor unit side is in an open state at present, the electric auxiliary thermal module can be controlled to improve the current power.
In another embodiment, if the current temperature of the indoor unit after the opening degree of the electronic expansion valve is adjusted is lower than the first set temperature, the opening degree of the electronic expansion valve may not be determined, and step S23 may be directly executed.
Because the regulation and control of the compressor can affect the temperature of the refrigerant of the whole refrigerant circulating system, the temperature of the indoor unit side of the air conditioner can be regulated and controlled, the temperature of the refrigerant in other heat exchangers in other systems can be affected, and particularly, when the other heat exchangers are still in a heat exchange state with the external air of the air conditioner, the temperature regulating effect of the other heat exchangers on the environment can be affected, and the comfort of users in the environment can be affected; and the indoor fan can cause the influence to the inside airflow that blows to the outside of air conditioner when realizing the regulation and control of the indoor machine side temperature of air conditioner, especially when the indoor machine side of air conditioner still is in the state with the heat transfer of air conditioner outside, can influence the air conditioner to the temperature regulation effect of environment (if can't satisfy user's amount of wind demand), influence user's travelling comfort in the environment. And the operation of the electric auxiliary heating module needs to consume extra energy. Based on this, the present embodiment preferentially adopts electronic expansion valve to regulate and control the temperature of the indoor machine side of air conditioner, can avoid compressor regulation and control and fan regulation and control to the air conditioner to the negative effects of the temperature regulation and control effect of environment, the regulation effect of electronic expansion valve can realize that indoor heat exchanger can maintain its heat transfer state operation, still can avoid high temperature refrigerant to flow to the heat exchange effect of heat exchanger behind the influence and reduce the compressor load behind, the realization carries out comprehensive effectual disinfection to the indoor machine side and guarantees that the air conditioner has better heat transfer efficiency to the environment with guaranteeing, can save the energy of extra consumption simultaneously. And when the regulation effect of the electronic expansion valve can not realize that the side of the indoor unit is more than or equal to the first set temperature, the regulation effect of the compressor or the indoor fan or the electric auxiliary heating module at the side of the indoor unit is used, so that the viruses on the side of the indoor unit of the air conditioner can be comprehensively killed in the first set time.
Further, based on any of the above embodiments, another embodiment of the air conditioner control method of the present application is provided. In this embodiment, referring to fig. 4, before the step S20, the method further includes:

when the current temperature of the indoor unit side of the air conditioner is greater than the second set temperature, step S03 is performed, and when the current temperature of the indoor unit side of the air conditioner is less than or equal to the second set temperature, step S04 or step S05 may be performed.
The second set temperature is specifically set according to a maximum temperature allowed by an indoor unit side of the air conditioner when the air conditioner is reliably operated, and a temperature value obtained by reducing the allowed maximum temperature by a preset temperature can be used as the second set temperature. The current temperature of the indoor unit side of the air conditioner is higher than the second set temperature, and it is considered that the air conditioner cannot be reliably operated because the indoor unit side temperature of the air conditioner is continuously increased. And if the current temperature of the indoor unit side of the air conditioner is less than or equal to the second set temperature, the current temperature state of the indoor unit side of the air conditioner can be considered to ensure that the air conditioner can reliably run.

Here, the adjustment method for adjusting the opening degree of the electronic expansion valve is the reverse of the adjustment method for increasing the temperature on the indoor unit side in step S20 in the above embodiment. For example, in the above embodiment, when the temperature on the indoor unit side is increased by decreasing the opening degree of the electronic expansion valve, the temperature on the indoor unit side is decreased by increasing the opening degree of the electronic expansion valve. Specifically, controlling the electronic expansion valve to adjust the opening degree so that the temperature of the indoor unit side of the air conditioner is less than or equal to the second set temperature may include the following adjustment rules: acquiring a temperature difference between the current temperature of the indoor unit side of the air conditioner and the second set temperature as a second temperature difference; and controlling the electronic expansion valve to adjust the opening according to the second temperature difference so that the temperature of the indoor unit side of the air conditioner is less than or equal to the second set temperature. In addition, a second set range is obtained to control the electronic expansion valve to adjust the opening degree so that the temperature of the indoor unit side of the air conditioner is less than or equal to the second set temperature. In addition, the electronic expansion valve may be controlled to adjust the opening degree so that the temperature of the indoor unit side of the air conditioner is less than or equal to the second set temperature, based on a second set coefficient and the current opening degree of the electronic expansion valve.
The generation rule of the adjustment range of the electronic expansion valve is various, and one of the multiple generation rules may be selected arbitrarily, or one of the multiple generation rules may be selected as the generation rule of the adjustment range of the opening degree of the electronic expansion valve according to the current operation state of the air conditioner. Specifically, step S03 may include: acquiring a temperature difference between the current temperature of the indoor unit side of the air conditioner and the second set temperature as a second temperature difference; determining a second generation rule of the adjustment amplitude of the electronic expansion valve according to the second temperature difference; determining a second adjustment amplitude of the electronic expansion valve according to the second generation rule; and controlling an electronic expansion valve of the air conditioner to adjust the opening according to the second adjustment amplitude so that the temperature of the indoor unit side of the air conditioner is less than or equal to the second set temperature.
Specifically, the step of determining the second generation rule of the adjustment range of the electronic expansion valve according to the second temperature difference includes: when the second temperature difference is in a fourth interval, determining the second generation rule as a second adjustment amplitude of the electronic expansion valve according to the second temperature difference; when the second temperature difference is in a fifth interval, determining the second generation rule as a second adjustment amplitude of the electronic expansion valve according to a second set amplitude; when the second temperature difference is in a sixth interval, determining that the second generation rule is to determine a second adjustment amplitude of the electronic expansion valve according to a second set coefficient and the current opening degree of the electronic expansion valve; wherein the numerical value in the fourth interval is greater than the numerical value in the fifth interval, and the numerical value in the fifth interval is greater than the numerical value in the sixth interval.
Further, the second generating rule for determining the second adjustment amplitude of the electronic expansion valve according to the second temperature difference includes: determining a second opening adjustment value according to the second temperature difference, and acquiring a second correction value of the second opening adjustment value, wherein the second correction value is determined according to the current compressor frequency of the air conditioner and the rotating speed of the indoor fan; and determining a second adjustment amplitude of the electronic expansion valve according to the second opening degree adjustment value and the second correction value.
Further, before the step of determining that the second generation rule is a second adjustment range of the electronic expansion valve according to a second set range, the method further includes: and acquiring the second set amplitude according to the current compressor frequency and the indoor fan rotating speed of the air conditioner.
Further, before the step of determining that the second generation rule is to determine a second adjustment range of the electronic expansion valve according to a second setting coefficient and the current opening degree of the electronic expansion valve, the method further includes: and acquiring the second set coefficient according to the current compressor frequency and the indoor fan rotating speed of the air conditioner.
In a specific implementation process of the foregoing embodiment, after determining an adjustment manner (increasing the opening degree or decreasing the opening degree) of the electronic expansion valve based on a relationship between the electronic expansion valve and the indoor unit side temperature to decrease the indoor unit side temperature, the second set temperature may be compared with the first set temperature, a second adjustment range of the electronic expansion valve is determined by referring to the specific implementation manners in step S20, step S201 to step S204 in the foregoing embodiment, and the opening degree of the electronic expansion valve is adjusted according to the determined second adjustment range, so as to achieve the technical effects brought by the opening degree adjustment implementation manner in the foregoing embodiment, which is not described herein again.
Step S20 may be repeatedly executed for a predetermined period of time (less than the first set time). Specifically, a second time point at which step S03 is executed for the first time may be recorded, and if the length of the time interval between the current time point and the second time point does not exceed a predetermined time period, the opening degree of the electronic expansion valve may be continuously adjusted so that the indoor unit side temperature is less than or equal to the second set temperature.
And step S04, controlling the electronic expansion valve to maintain the current opening degree.
And step S05, controlling the electronic expansion valve to adjust the opening degree so as to increase the temperature of the indoor unit side of the air conditioner and control the indoor fan to increase the running speed.
The process of adjusting the opening of the electronic expansion valve can be similar to the specific implementation process of the opening of the electronic expansion valve in step S20, and is not described herein again.

The adjustment mode of the running rotating speed of the indoor fan can be set according to actual conditions, and the fan is controlled to increase the running rotating speed according to preset adjustment parameters and/or the running state of the air conditioner. Specifically, the adjustment range of the rotating speed of the indoor fan can be determined according to the current temperature of the indoor unit side of the air conditioner and the current rotating speed of the indoor fan, and the operating rotating speed of the indoor fan is increased according to the determined adjustment range.
In another embodiment, if the current temperature of the indoor unit side of the air conditioner after the opening degree of the electronic expansion valve is adjusted is still higher than the second set temperature, the step S04 or the step S05 may be directly executed without determining the opening degree of the electronic expansion valve. After the step S05 is executed, the process may return to the step S01. Further, in other embodiments, it is also possible to directly perform step S04 or step S05 without further comparing the temperature of the indoor side of the air conditioner with the second set temperature when it is determined that the current temperature of the indoor side of the air conditioner is greater than or equal to the first set temperature based on step S01.
In this embodiment, based on the setting of the second set temperature, the opening degree of the electronic expansion valve is adjusted when the current temperature of the indoor unit side of the air conditioner exceeds the second set temperature, so that the current temperature of the indoor unit side is reduced below the second set temperature, thereby ensuring reliable operation of the air conditioner. In addition, when the indoor unit side of the air conditioner is higher than the first set temperature but not higher than the second set temperature, the air conditioner can reliably run and can effectively kill viruses, and the opening degree of the electronic expansion valve is maintained at the moment, so that the temperature of the indoor unit side can effectively kill the viruses. In addition, when the indoor unit side of the air conditioner is higher than the first set temperature but not higher than the second set temperature, the adjusting mode of increasing the temperature of the indoor heat exchanger such as the opening degree of the electronic expansion valve can be continuously reduced, the rotating speed of the indoor fan is increased at the same time, high-temperature hot air can be guaranteed to be blown out indoors, the indoor environment can be sterilized while the indoor unit side of the air conditioner is sterilized, the temperature of the indoor heat exchanger is further increased by adjusting the opening degree of the electronic expansion valve, the influence of the indoor environment sterilization on the sterilizing effect of the indoor unit side of the air conditioner can be avoided, and the comprehensive sterilization of viruses on the indoor unit side of the air conditioner within the first set time is guaranteed.

if the current temperature of the indoor unit side of the air conditioner is higher than the second set temperature, executing step S07; if the current temperature of the indoor unit side of the air conditioner is less than or equal to the second set temperature, the electronic expansion valve, the indoor fan, the compressor and other components in the air conditioner can be controlled to maintain the current state operation, the electronic expansion valve can also be controlled to continuously adjust the opening degree to increase the temperature of the indoor unit side, the control can be performed according to the relevant mode of the step S04 or the step S05, even other control modes can be provided according to the actual requirement, and in addition, the step S01 can be returned to.
Specifically, when the duration of the execution of step S03 reaches the above-mentioned preset time period, step S06 may be executed.
Step S07, judging whether the current opening degree of the electronic expansion valve is in a second opening degree range;
when the current opening degree of the electronic expansion valve is in the second opening degree range, performing step S08; and when the current opening degree of the electronic expansion valve is outside the second opening degree range, returning to the step S03.
The second opening range may be set according to the actual condition of the air conditioner. If the current opening degree is within the second opening degree range, it can be considered that the temperature of the indoor unit side of the air conditioner cannot be reduced continuously due to the fact that the current opening degree of the electronic expansion valve is adjusted continuously, and even the air conditioner cannot run normally; the current opening degree is outside the second opening degree range, and it can be considered that the current opening degree of the electronic expansion valve can achieve effective reduction of the temperature of the indoor unit side of the air conditioner by continuing adjustment. For example, when the opening degree of the electronic expansion valve is increased to lower the indoor-unit-side temperature, the second opening degree range may be divided based on the second opening degree threshold value, and an opening degree value equal to or greater than the second opening degree threshold value may be divided into the second opening degree range.

The improvement of the rotating speed of the indoor fan can increase the heat quantity of the indoor unit side taken away when the air is blown to the outside of the air conditioner from the indoor unit side, so that the temperature of the indoor unit side can be reduced; the reduction of the running frequency of the compressor can reduce the temperature of the refrigerant at the refrigerant outlet, so that the temperature of the refrigerant flowing into the indoor unit side is reduced, and the temperature reduction of the indoor unit side is realized; the reduction of the power of the electric auxiliary thermal module at the indoor machine side can reduce the heat productivity of the electric auxiliary thermal module at the indoor machine side, thereby realizing the temperature reduction of the indoor machine side.
In order to ensure the accuracy of the temperature regulation of the indoor unit side by the matching of the indoor fan, the compressor and the electronic expansion valve, the regulation parameters of the fan can be determined according to the current temperature of the indoor unit side, the current opening degree of the electronic expansion valve and the frequency of the compressor, and the indoor fan is controlled to increase the running speed according to the determined regulation parameters; and the adjustment parameters of the compressor can be determined according to the current temperature of the indoor unit side, the current opening degree of the electronic expansion valve and the rotating speed of the indoor fan, and the operation frequency of the compressor is controlled to be reduced according to the determined adjustment parameters. In addition, the step of controlling the power reduction of the indoor unit side electric auxiliary thermal module comprises: when the electric auxiliary thermal module on the indoor unit side is in a closed state at present, controlling the electric auxiliary thermal module to maintain the state that the current power is 0; when the electric auxiliary thermal module on the indoor unit side is in the on state, the electric auxiliary thermal module can be controlled to reduce the power to be below the threshold value and set to be reduced to 0 (namely, the electric auxiliary thermal module is turned off).
In another embodiment, if the current temperature of the indoor unit after the opening degree of the electronic expansion valve is adjusted exceeds the second set temperature, the opening degree of the electronic expansion valve may not be determined, and step S08 may be directly executed.
Because the regulation and control of the compressor can affect the temperature of the refrigerant of the whole refrigerant circulating system, the temperature of the indoor unit side can be regulated and controlled, the temperature of the refrigerant in other heat exchangers in other systems can be affected, and particularly, when the other heat exchangers are still in a heat exchange state with the external air of the air conditioner, the temperature regulating effect of the other heat exchangers on the environment can be affected, and the comfort of users in the environment can be affected; and can cause the influence to the inside airflow that blows to the outside of air conditioner when indoor fan realizes that indoor machine side temperature regulation and control, especially when the indoor machine side still is in the state with the heat transfer of air conditioner outside air, can influence the air conditioner to the temperature regulation effect of environment (if can't satisfy user's amount of wind demand), influence user's travelling comfort in the environment. And the electricity is assisted the thermal module and is less relatively to air conditioning system reliability influence, and based on this, the temperature of this embodiment priority adoption electronic expansion valve to indoor machine side is regulated and control, can avoid compressor regulation and control and indoor fan regulation and control to the air conditioner to the negative effects of the temperature regulation and control effect of environment, and the regulation of electron expansion valve realizes carrying out comprehensive effectual disinfection to indoor machine side with guaranteeing that the air conditioner has better heat transfer efficiency to the environment. And when the regulation effect of the electronic expansion valve can not avoid the overhigh temperature of the indoor unit side, the reliable operation of the air conditioner system is effectively ensured through the regulation effect of the compressor or the indoor fan or the electric auxiliary heating module.

When the environment temperature is lower, the indoor fan is stopped, hot air is prevented from blowing indoors, and the comfort of indoor environment users can be ensured; when the environmental temperature is lower, the indoor fan keeps running in the process of disinfection, so that hot air can be blown to the indoor to regulate and control the indoor temperature, and the comfort of indoor environment users is guaranteed while the disinfection of the air conditioner is realized.
In this embodiment, at the initial stage of entering the first operation mode, the compressor of the air conditioner is controlled to operate at the first frequency, the indoor fan is controlled to operate at the first rotation speed, and the electronic expansion valve is controlled to operate at the first opening degree for the second set time, so that after the temperature of the indoor unit side is increased and is in a stable state, the electronic expansion valve is further controlled based on the temperature of the indoor unit side, and the stability of the operation of the air conditioner system can be ensured while the effectiveness of the air-conditioner indoor unit side in killing viruses is ensured.
