[0030] In this embodiment, a method for controlling an air conditioner running on a mobile terminal, a computer terminal or a similar computing device is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0031] Figure 2 FIG. 1 is a flow chart of a method for controlling an air conditioner according to an embodiment of the present application. Figure 2 As shown, the method comprises the following steps:

[0032] Step S201, obtaining the indoor ambient temperature and outdoor ambient temperature of the air conditioner;

[0033] Specifically, after the equipment room air conditioner is started, the indoor and outdoor ambient temperatures are monitored in real time, which are completed by the indoor ambient temperature sensing package installed in the indoor unit and the outdoor ambient temperature sensing package installed in the outdoor unit, respectively, and recorded by the controller chip to provide a data basis for the follow-up. Since the equipment room air conditioner is mainly used to cool high-heat units and equipment, this control logic is applied in the cooling mode.

[0034] Step S202, adjusting the current operating parameters of the air conditioner according to the magnitude relationship between the indoor ambient temperature and the outdoor ambient temperature to obtain target operating parameters, wherein when the difference between the outdoor ambient temperature and the indoor ambient temperature is greater than a first preset difference and less than or equal to a second preset difference, at least the frequency of the outdoor compressor of the air conditioner is reduced to a target frequency, and the current operating parameters at least include the frequency of the outdoor compressor of the air conditioner at the current moment;

[0035] Specifically, when the outside ambient temperature is lower than the indoor ambient temperature, cooling is achieved by introducing cold air from the outdoor side into the indoor side, fully developing the function and efficiency of the air conditioner and extending the service life of the air conditioner.

[0036] According to the relationship between the indoor ambient temperature and the outdoor ambient temperature, adjusting the current operating parameters of the air conditioner to obtain the target operating parameters comprises the following steps:

[0037] Step S301, obtaining the difference between the outdoor ambient temperature and the indoor ambient temperature to obtain a target difference;

[0038] Step S302, obtaining a ratio of the outdoor ambient temperature to the indoor ambient temperature to obtain a target ratio;

[0039] Step S303, adjusting the current operating parameters of the air conditioner according to the target difference and / or the target ratio to obtain the target operating parameters.

[0040] Specifically, the operating parameters of the air conditioner can be effectively determined according to the target difference and / or target ratio, thereby fully developing the functions and usage efficiency of the air conditioner, so that the air conditioner does not need to be turned on for cooling all year round, while saving energy.

[0041] According to the target difference, adjusting the current operating parameters of the air conditioner to obtain the target operating parameters comprises the following steps:

[0042] Step S401, when the target difference is less than or equal to the first preset difference, the indoor fan of the air conditioner and the centrifugal fan of the fresh air system are adjusted to the maximum speed, and the outdoor compressor and the outdoor fan of the air conditioner are stopped to obtain the target operating parameters;

[0043] Step S402, when the target difference is greater than the first preset difference and less than or equal to the second preset difference, the frequency of the outdoor compressor of the air conditioner is reduced to the target frequency, the wind speed of the outdoor fan of the air conditioner is reduced to the target outdoor fan speed, the indoor fan of the air conditioner is increased to the target indoor fan speed, and the centrifugal fan of the air conditioner is adjusted to the maximum speed to obtain the target operating parameters, and the second preset difference is greater than the first preset difference;

[0044] Step S403: when the target difference is greater than the second preset difference, the current operating parameters of the air conditioner are kept unchanged.

[0045] Specifically, when the outdoor ambient temperature is more than 3°C lower than the indoor ambient temperature, the temperature difference between the two is large and there is no need for air conditioning to assist in cooling. At this time, the indoor unit starts the fresh air system and the centrifugal fan runs at the highest speed to draw outdoor air into the room. The filter screen filters out debris to keep the air duct clean and unobstructed. The outdoor unit compressor stops and the outdoor fan stops to save energy. The power is no longer turned on and the indoor unit fan runs at the highest speed to increase the air volume and facilitate heat exchange. When the outdoor ambient temperature is ≤3°C lower than the indoor ambient temperature, the temperature difference between the two is not large and there is need for air conditioning to assist in cooling. At this time, the outdoor unit compressor runs at half the current frequency and the outdoor fan speed drops to the lower gear of the current wind speed. The indoor unit starts the centrifugal fan and the fresh air system to draw outdoor air into the room and the indoor fan speed is increased by one wind speed. Air conditioning refrigeration and natural wind cooling control operate simultaneously and assist each other to achieve the purpose of cooling and energy saving; when the outdoor ambient temperature is ≥ the indoor ambient temperature, it means that the outdoor air temperature is higher than the indoor air temperature. At this time, the outdoor air cannot be drawn in to cool the indoor air, and the purpose of cooling the unit equipment cannot be achieved. Therefore, the air conditioner continues to cool according to the current mode, speed and frequency.

[0046] Among them, the first preset difference is -3, and the second preset difference is 0. The above preset difference can ensure that there is a certain heat exchange temperature difference between the inner and outer ring temperatures, and ensure the cooling of the indoor equipment. If it is set too high, it will affect the energy consumption efficiency, and if it is set too low, it will affect the cooling of the equipment.

[0047] It should be noted that the first preset difference and the second preset difference can be adjusted according to actual conditions and are not limited to the above values.

[0048] According to the target ratio, adjusting the current operating parameters of the air conditioner to obtain the target operating parameters comprises the following steps:

[0049] Step S501, when the target ratio is less than or equal to the first preset ratio, the indoor fan of the air conditioner and the centrifugal fan of the fresh air system are adjusted to the maximum speed, and the outdoor compressor and the outdoor fan of the air conditioner are stopped to obtain the target operating parameters;

[0050] Step S502, when the target ratio is greater than the first preset ratio and less than or equal to the second preset ratio, the frequency of the outdoor compressor of the air conditioner is reduced to the target frequency, the wind speed of the outdoor fan of the air conditioner is reduced to the target outdoor fan speed, the indoor fan of the air conditioner is increased to the target indoor fan speed, and the centrifugal fan of the air conditioner is adjusted to the maximum speed to obtain the target operating parameters, and the second preset ratio is greater than the first preset ratio;

[0051] Step S503: when the target ratio is greater than the second preset ratio, keep the current operating parameters of the air conditioner unchanged.

[0052] Specifically, when the outdoor ambient temperature / indoor ambient temperature is less than 0.75, the temperature difference between the two is large, and there is no need for air conditioning to assist in cooling. At this time, the indoor unit starts the fresh air system and the centrifugal fan runs at the highest speed to draw outdoor air into the room. The filter screen filters out debris to keep the air duct clean and unobstructed. The outdoor unit compressor stops and the outdoor fan stops to save energy. The power is no longer turned on and the indoor unit fan runs at the highest speed to increase the air volume and facilitate heat exchange; 0.75≤outdoor ambient temperature / indoor ambient temperature<1, the temperature difference between the two is not large, and air conditioning is needed to assist in cooling. At this time, the outdoor unit compressor runs at half the current frequency, and the outdoor fan speed is reduced to the lower gear of the current wind speed. The indoor unit starts the centrifugal fan and the fresh air system to draw outdoor air into the room, and the indoor fan speed is increased by one wind speed. Air conditioning refrigeration and natural wind cooling control operate simultaneously and assist each other to achieve the purpose of cooling and energy saving; when the outdoor ambient temperature ≥ the indoor ambient temperature, that is, the outdoor ambient temperature / indoor ambient temperature ≥ 1, it means that the outdoor air temperature is higher than the indoor air temperature. At this time, the outdoor air cannot be drawn in to cool the indoor air, and the purpose of cooling the unit equipment cannot be achieved. Therefore, the air conditioner continues to cool according to the current mode, speed, and frequency.

[0053] The first preset ratio is 0.75, and the second preset ratio is 1. The above preset ratio can ensure that there is a certain heat exchange temperature difference between the inner and outer ring temperatures, and ensure the cooling of the indoor equipment. If it is set too high, it will affect the energy consumption efficiency, and if it is set too low, it will affect the cooling of the equipment.

[0054] Among them, the above-mentioned target frequency is half of the preset frequency corresponding to the current operating condition of the above-mentioned outdoor compressor, the above-mentioned target external fan gear is one gear lower than the preset wind gear corresponding to the current operating condition of the above-mentioned outdoor unit fan, and the above-mentioned target internal fan gear is one gear higher than the preset wind gear corresponding to the current operating condition of the above-mentioned indoor unit fan.

[0055] Specifically, when the outdoor ambient temperature is ≤3°C below the indoor ambient temperature, the temperature difference between the two is not large and air conditioning is needed to assist in cooling. At this time, the outdoor unit compressor runs at half the current frequency, and the outdoor fan speed is reduced to a lower level of the current wind speed. The indoor unit starts the centrifugal fan, starts the fresh air system, draws outdoor air into the room, and the indoor fan speed is increased by one wind speed.

[0056] Before adjusting the operating parameters of the air conditioner according to the magnitude relationship between the indoor ambient temperature and the outdoor ambient temperature to obtain the target operating parameters, the method further comprises the following steps:

[0057] Step S601, obtaining indoor environmental humidity and outdoor environmental humidity, wherein the indoor environmental humidity is the environmental humidity in the space where the air conditioner is located, and the outdoor environmental humidity is the environmental humidity in the space where the air conditioner is not located;

[0058] Step S602, determining the current operating condition of the air conditioner according to the indoor ambient temperature, indoor ambient humidity, outdoor ambient temperature and outdoor ambient humidity;

[0059] Step S603, according to the current operating conditions, the corresponding operating parameters of the air conditioner are determined to obtain the current operating parameters.

[0060] Specifically, the parameters corresponding to the rated operating conditions are: indoor ambient temperature of 26°C, indoor ambient humidity of 60% RH (relative humidity), outdoor ambient temperature of 35°C, and outdoor ambient humidity of 50% RH; the parameters corresponding to the low temperature operating conditions are: indoor ambient temperature of 20°C, indoor ambient humidity of 50%-60% RH (relative humidity), outdoor ambient temperature of 29°C, and outdoor ambient humidity of 50% RH.

[0061] Wherein, determining the current operating condition of the air conditioner according to the indoor ambient temperature, indoor ambient humidity, outdoor ambient temperature and outdoor ambient humidity comprises the following steps:

[0062] Step S6021, obtaining a target mapping relationship, wherein the target mapping relationship is a mapping relationship between the outdoor ambient temperature, the indoor ambient temperature, the outdoor ambient humidity, the indoor ambient humidity and the operating conditions of the air conditioner;

[0063] Step S6022, determining the current operating condition of the air conditioner according to the indoor ambient temperature, indoor ambient humidity, outdoor ambient temperature, outdoor ambient humidity and the target mapping relationship at the current moment.

[0064] Specifically, the current operating condition of the air conditioner is determined, thereby determining the corresponding operating parameters of the air conditioner, and controlling the air conditioning refrigeration and natural wind cooling to assist each other to achieve the purpose of cooling and energy saving.

[0065] Step S203, controlling the air conditioner to operate according to the target operating parameters to reduce the power consumption of the air conditioner to a preset power consumption.

[0066] Specifically, air conditioning refrigeration and natural wind cooling control operate simultaneously and assist each other to achieve the purpose of cooling and energy saving, avoiding year-round refrigeration operation, thereby reducing power consumption and extending the service life of the air conditioner.

[0067] The control method of the air conditioner of the present application first obtains the indoor ambient temperature and outdoor ambient temperature of the air conditioner; then, according to the size relationship between the indoor ambient temperature and the outdoor ambient temperature, the current operating parameters of the air conditioner are adjusted to obtain the target operating parameters, wherein, when the difference between the outdoor ambient temperature and the indoor ambient temperature is greater than the first preset difference and less than or equal to the second preset difference, at least the frequency of the outdoor compressor of the air conditioner is reduced to the target frequency, and the current operating parameters at least include the frequency of the outdoor compressor of the air conditioner at the current moment; finally, the air conditioner is controlled to operate according to the target operating parameters to reduce the power consumption of the air conditioner to the preset power consumption. When the external ambient temperature is lower than the indoor ambient temperature, the method achieves the purpose of heat exchange and saves energy by introducing the outdoor cold air into the indoor side, that is, using natural wind to assist in cooling the equipment, fully developing the function and use efficiency of the air conditioner, thereby extending the service life of the air conditioner, and solving the problem that the computer room air conditioner in the prior art needs to be turned on all year round for refrigeration operation, resulting in a short service life and high energy consumption of the computer room air conditioner.

[0068] In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the implementation process of the air conditioner control method of the present application will be described in detail below in conjunction with specific embodiments.

[0069] This embodiment relates to a specific air conditioner control method, such as Figure 3As shown, the steps include: turning on the air conditioner and detecting the indoor and outdoor ambient temperatures; when the outdoor ambient temperature is ≥ the indoor ambient temperature, the air conditioner continues to cool according to the current mode, speed and frequency; when the outdoor ambient temperature is < the indoor ambient temperature by more than 3°C, the fresh air system is started, the centrifugal fan has the highest speed, the outdoor air is drawn into the room, the filter screen filters out debris, the outdoor unit compressor is stopped, the outdoor fan is stopped, and the indoor unit fan runs at the highest speed; when the outdoor ambient temperature is ≤ the indoor ambient temperature by less than 3°C, the outdoor unit compressor runs at half the current frequency, the outdoor fan speed is reduced to the lower gear of the current wind speed, the indoor unit starts the centrifugal fan, starts the fresh air system, draws the outdoor air into the room, and the indoor fan speed is increased by one wind speed.
