[0026] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described below in connection with specific embodiments of the present application and corresponding drawings. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0027] It is considered that, for the air conditioner with fresh air function, the introduction of fresh air indoors causes air conditioner condensation, and too much condensation can even cause air conditioner blowing water, resulting in poor air conditioner comfort. For example, hot air can form condensate on the surface of the evaporator, and also form water droplets in the areas of the air deflector and air sweeping blades. Cold air and hot air meet at the intersection and form condensate. The higher the humidity of the air, the more likely it is to cause condensation problems. Therefore, under the condition of introducing fresh air, the indoor and outdoor temperature difference and humidity difference to a certain extent determine the severity of the condensation problem. Therefore, the present application provides an air conditioner control method, specifically a condensation prevention control method for an air conditioner with fresh air function, to control the fresh air motor speed and compressor operating frequency based on the difference between the fresh air temperature and humidity and the indoor temperature and humidity, adjust the fresh air motor speed and compressor operating frequency through effective condensation prevention control means to achieve condensation prevention control, achieve condensation prevention effect, improve air conditioner comfort, and improve user experience.

[0028] According to an embodiment of the present application, a control method for an air conditioner is provided, as shown in Figure 1 The flowchart of an embodiment of the method of the present application. The air conditioner has a fresh air function, and the air conditioner also has a fresh air motor and a compressor. The control method of the air conditioner comprises steps S110 to S130.

[0029] At step S110, during the operation of the air conditioner, the outdoor environment temperature of the air conditioner is obtained, denoted as the fresh air temperature (such as fresh air temperature T 新风 ) of the air conditioner. The outdoor environment humidity of the air conditioner is obtained, denoted as the fresh air humidity (such as fresh air humidity RH 新风 ) of the air conditioner. The indoor environment temperature (such as indoor environment temperature T 室内 ) of the air conditioner is obtained, and the indoor environment humidity (such as indoor environment humidity RH 室内 ) of the air conditioner is obtained.

[0030] Specifically, in the scheme of the present application, for an air conditioner with fresh air function, a temperature and humidity sensor is arranged at the indoor evaporator (i.e. indoor heat exchanger) and the outdoor condenser (i.e. outdoor heat exchanger) of the air conditioner respectively. For example, a temperature and humidity sensor (or a temperature sensor and a humidity sensor) is installed at the indoor evaporator side to detect the indoor environment temperature and humidity, and a temperature and humidity sensor is installed at the outdoor condenser side to detect the outdoor environment temperature and humidity. In the scheme of the present application, when a condensation prevention control method for an air conditioner with fresh air function is performed, the fresh air temperature and humidity are set to be the same as the outdoor environment temperature and humidity by default, and the difference between the fresh air temperature and the indoor environment temperature is defined as ΔT=T 新风 - the indoor environment temperature T 室内 , and the difference between the fresh air humidity and the indoor environment humidity is defined as ΔRH=RH 新风 - the indoor environment humidity RH 室内 .

[0031] At step S120, the difference between the fresh air temperature of the air conditioner and the indoor environment temperature of the air conditioner is determined, which is recorded as the fresh air temperature difference of the air conditioner, such as the difference ΔT=T 新风 - the indoor environment temperature T 室内 of the fresh air temperature and the indoor environment temperature. And the difference between the fresh air humidity of the air conditioner and the indoor environment humidity of the air conditioner is determined, which is recorded as the fresh air humidity difference of the air conditioner, such as the difference ΔRH=RH 新风 - the indoor environment humidity RH 室内 .

[0097] Specifically, the anti-condensation control method of the air conditioner with fresh air function provided by the scheme of the present application further comprises:

[0098] Step 4: When the current operation mode of the air conditioner is the cooling mode with fresh air, strategy B is executed after the fresh air is opened for 3 minutes, and the fresh air motor speed and the compressor operation frequency are controlled according to the difference ΔT between the fresh air temperature and the indoor environment temperature and the difference ΔRH between the fresh air humidity and the indoor environment humidity. Strategy B is as follows: the control is executed according to the range of the difference ΔT between the fresh air temperature and the indoor environment temperature and the difference ΔRH between the fresh air humidity and the indoor environment humidity. Since the compressor is running in the cooling mode, the fresh air is opened in the cooling mode, and the fresh air motor speed and the compressor operation frequency are controlled. Since the outdoor temperature is higher than the indoor temperature in most cases when the cooling mode is opened, the temperature of the introduced fresh air is higher than the indoor temperature by default.

[0103] Step 42: The difference ΔRH between the fresh air humidity and the indoor environment humidity is determined according to the difference ΔRH between the fresh air humidity and the indoor environment humidity.

[0104] ① When the fourth set humidity such as 30% < the difference ΔRH between the fresh air humidity and the indoor environment humidity, record this condition as condition a.

[0105] ② When the third set humidity, such as 10%, < the difference ΔRH between the fresh air humidity and the indoor environment humidity ≤ the fourth set humidity, such as 30%, record this condition as condition b.

[0106] ③ When the second set humidity, such as -10%, < the difference ΔRH between the fresh air humidity and the indoor environment humidity ≤ the third set humidity, such as 10%, record this condition as condition c.

[0107] ④ When the first set humidity, such as -30%, < the difference ΔRH between the fresh air humidity and the indoor environment humidity ≤ the second set humidity, such as -10%, record this condition as condition d.

[0108] ⑤ When the difference ΔRH between the fresh air humidity and the indoor environment humidity ≤ the first set humidity, such as -30%, record this condition as condition e.

[0109] In some embodiments, the current operation mode of the air conditioner is the heating mode with fresh air operation mode.

[0110] Correspondingly, in the current operation mode of the air conditioner in step S130, based on the preset temperature range and the preset humidity range, according to the fresh air temperature difference of the air conditioner and the fresh air humidity difference of the air conditioner, the speed of the fresh air motor of the air conditioner is controlled, or the speed of the fresh air motor of the air conditioner and the frequency of the compressor of the air conditioner are controlled, to realize the anti-condensation control of the air conditioner, and the process of anti-condensation control in the heating mode with fresh air operation mode is further included.

[0111] The first anti-condensation control case in the heating mode with fresh air: if the fresh air temperature difference of the air conditioner is greater than the second set temperature, then:

[0121] In the case that the fresh air humidity difference of the air conditioner is greater than the second set humidity and less than or equal to the third set humidity, the fresh air motor of the air conditioner is controlled to run at the current speed, and the compressor of the air conditioner is controlled to run at the current frequency, the current speed being the set default speed and the current frequency being the set default frequency.

[0122] In the case that the fresh air humidity difference of the air conditioner is less than or equal to the first set humidity, the fresh air motor of the air conditioner is controlled to operate at the current rotating speed, and the compressor of the air conditioner is controlled to operate at the current frequency, the current rotating speed being the set default rotating speed, and the current frequency being the set default frequency.

[0123] In the case that the fresh air humidity difference of the air conditioner is less than or equal to the first set humidity, the fresh air motor of the air conditioner is controlled to operate at the current rotating speed, and the compressor of the air conditioner is controlled to operate at the current frequency, the current rotating speed being the set default rotating speed, and the current frequency being the set default frequency.

[0124] In the case that the fresh air humidity difference of the air conditioner is greater than the fourth set humidity, the fresh air motor of the air conditioner is controlled to operate at the current rotating speed minus the fourth set rotating speed, and the compressor of the air conditioner is controlled to operate at the current frequency minus the first set frequency, the fourth set rotating speed being, for example, 400 r, and the first set frequency being, for example, 5 Hz.

[0125] In the case that the fresh air humidity difference of the air conditioner is greater than the third set humidity and less than or equal to the fourth set humidity, the fresh air motor of the air conditioner is controlled to operate at the current rotating speed minus the fifth set rotating speed, and the compressor of the air conditioner is controlled to operate at the current frequency minus the first set frequency, the fifth set rotating speed being less than the fourth set rotating speed, the fifth set rotating speed being, for example, 300 r, and the first set frequency being, for example, 5 Hz.

[0127] In the case that the fresh air humidity difference of the air conditioner is greater than the first set humidity and less than or equal to the second set humidity, the fresh air motor of the air conditioner is controlled to operate at the current rotating speed minus the second set rotating speed, and the compressor of the air conditioner is controlled to operate at the current frequency, the first set rotating speed being, for example, 100 r, and the current frequency being the set default frequency.

[0128] In the case that the fresh air humidity difference of the air conditioner is less than or equal to the first set humidity, the fresh air motor of the air conditioner is controlled to operate at the current rotating speed, and the compressor of the air conditioner is controlled to operate at the current frequency, the current rotating speed being the set default rotating speed, and the current frequency being the set default frequency.

[0129] Specifically, the anti-condensation control method of the air conditioner with the fresh air function further comprises the following steps.

[0130] Step 5, when the current operation mode of the air conditioner is the heating mode open fresh air, after the fresh air is opened for 3 minutes, strategy C is executed, the difference AT between the fresh air temperature and the indoor environment temperature, the difference ARH between the fresh air humidity and the indoor environment humidity are used to control the fresh air motor speed and the compressor operation frequency, strategy C is as follows: according to the range of the difference AT between the fresh air temperature and the indoor environment temperature, the difference ARH between the fresh air humidity and the indoor environment humidity, the control is determined to be executed, since the compressor is running in the heating mode, the fresh air is opened in the heating mode, and the fresh air motor speed and the compressor operation frequency are controlled. Since the outdoor temperature is lower than the indoor temperature in most cases when the heating mode is opened, the temperature of the introduced fresh air is lower than the indoor temperature by default.

[0131] Step 51, as shown in (c) of Figure 3 Step 51, as shown in (c) of

[0132] ① When the second set temperature is -5℃ < the difference AT between the fresh air temperature and the indoor environment temperature, record this condition as condition 1.

[0133] ② When the first set temperature is -10℃ < the difference AT between the fresh air temperature and the indoor environment temperature ≤ the second set temperature -5℃, record this condition as condition 2.

[0134] ③ When the difference AT between the fresh air temperature and the indoor environment temperature ≤ the first set temperature -10℃, record this condition as condition 3.

[0135] Step 52, according to the difference ARH between the fresh air humidity and the indoor environment humidity:

[0136] ① When the fourth set humidity is 30% < the difference ARH between the fresh air humidity and the indoor environment humidity, record this condition as condition a.

[0137] ② The third set humidity is 10% < the difference ARH between the fresh air humidity and the indoor environment humidity ≤ the fourth set humidity 30%, record this condition as condition b.

[0138] ③ The second set humidity is -10% < the difference ARH between the fresh air humidity and the indoor environment humidity ≤ the third set humidity 10%, record this condition as condition c.

[0139] ④ The first set humidity is -30% < the difference ARH between the fresh air humidity and the indoor environment humidity ≤ the second set humidity -10%, record this condition as condition d.

[0140] ⑤ The difference ARH between the fresh air humidity and the indoor environment humidity ≤ the first set humidity -30%, record this condition as condition e.

[0141] Step 6, after determining the above conditions, the following anti-condensation control is executed, and the new air motor speed and the compressor frequency are controlled to achieve more accurate anti-condensation control through the above steps. Figure 4 An action table is executed for all determination results in the anti-condensation control method of the air conditioner with a new air function of the present application, wherein (a) is an action table executed for all determination results in the case of opening new air in the air supply mode, (b) is an action table executed for all determination results in the case of opening new air in the refrigeration mode, and (c) is an action table executed for all determination results in the case of opening new air in the heating mode. Similarly, the action table executed for all determination results can be seen from the example shown in Figure 4

[0142] For example, in the air supply mode with new air (A strategy), the third set temperature is, for example, 5℃ < the difference ΔT between the new air temperature and the indoor environment temperature (condition 1), the fourth set humidity is, for example, 30% < the difference ΔRH between the new air humidity and the indoor environment humidity (condition a), that is, the determination result is A-1-a, and the action of reducing the new air motor speed by 200r is executed. The new air motor speed is reduced by 200r on the basis of the default speed (all reduced speeds are controlled on the basis of the default speed). The new air is operated at the default speed for 3 minutes, and then the anti-condensation logic determination is executed. For example, after the new air is opened for 3 minutes (for example, the default speed is 2000r), it is determined that A-1-a, and the current speed is 1800r (the default speed is reduced by 200r), and then the outdoor environment changes (the new air humidity decreases), and it is determined that A-1-b, and the current speed is 1900r (the default speed is reduced by 100r).

[0143] The basic principle of the determination of the anti-condensation control in the scheme of the present application is that the greater the indoor and outdoor temperature difference and the greater the difference ΔRH between the new air humidity and the indoor environment humidity, the more serious the condensation, and the more limited the anti-condensation means to the new air motor speed and the compressor frequency. Since the overall condensation in the air supply mode with new air is not as serious as the overall condensation in the refrigeration and heating modes with new air (in the refrigeration and heating modes, the user has a requirement for the room temperature, and the indoor temperature will not fluctuate greatly due to the action of introducing new air. In the air supply mode, the user has no great requirement for the room temperature, and the indoor temperature will fluctuate greatly due to the action of introducing new air), the control in the air supply mode with new air is simpler than the control in the refrigeration and heating modes with new air.

[0144] ​The anti-condensation control method provided in the scheme of the present application considers that the temperature and humidity difference between fresh air and indoor environment directly affects condensation, so the temperature difference between fresh air temperature and indoor environment temperature and the humidity difference between fresh air humidity and indoor environment humidity are calculated by collecting outdoor environment temperature (i.e. fresh air temperature), outdoor environment humidity (i.e. fresh air humidity), indoor environment temperature and outdoor environment temperature. The anti-condensation condition is determined according to the range of the temperature difference and the humidity difference, and different anti-condensation controls are performed. The anti-condensation means is to adjust the speed of the fresh air motor and the frequency of the compressor. The control means corresponding to different parameter ranges is subdivided. The anti-condensation control is determined according to the range of the temperature difference and the humidity difference. The division of the range of the temperature difference ΔT between fresh air temperature and indoor environment temperature, the humidity difference ΔRH between fresh air humidity and indoor environment humidity, the control of the speed of the fresh air motor and the control of the frequency of the compressor are only exemplary values to provide a control idea, and are not limited to the exemplary parameter values. Under different temperature differences between fresh air and indoor environment and different humidity differences between fresh air and indoor environment, the condensation of the air conditioner often has great differences. The present application gives the corresponding control means by subdividing the condensation conditions in different ranges. The anti-condensation control method is determined by the temperature difference ΔT between fresh air temperature and indoor environment temperature and the humidity difference ΔRH between fresh air humidity and indoor environment humidity, which is more reasonable and solves the condensation problem from the aspect of the formation reason of condensation.

[0145] By adopting the technical scheme of the present embodiment, in the process of running the air conditioner with fresh air function, the outdoor environment temperature (i.e. fresh air temperature), the outdoor environment humidity (i.e. fresh air humidity), the indoor environment temperature and the outdoor environment temperature are detected, the temperature difference between fresh air temperature and indoor environment temperature and the humidity difference between fresh air humidity and indoor environment humidity are calculated. According to the anti-condensation determination condition, the range of the calculated temperature difference and humidity difference is judged in the pre-subdivided range, and different anti-condensation control modes corresponding to the judgment result are executed according to the judgment result, so as to realize the anti-condensation control of the air conditioner with fresh air function. Therefore, the anti-condensation control is realized by adjusting the speed of the fresh air motor and the frequency of the compressor, and the user's use comfort is improved.

[0146] According to the embodiment of the present application, a control device of an air conditioner corresponding to the control method of the air conditioner is also provided. Referring to Figure 3 The device of the present application has an air conditioner with fresh air function, and the air conditioner also has a fresh air motor and a compressor. The control device of the air conditioner comprises an acquisition unit 102 and a control unit 104.

[0147] The acquisition unit 102 is configured to acquire the outdoor environment temperature of the air conditioner, denoted as the fresh air temperature of the air conditioner (such as fresh air temperature T 新风). The outdoor environment humidity of the air conditioner is acquired, denoted as the fresh air humidity (e.g., fresh air humidity RH 新风 ) of the air conditioner. 室内 The indoor environment temperature of the air conditioner is acquired (e.g., indoor environment temperature T 室内 ), and the indoor environment humidity of the air conditioner is acquired (e.g., indoor environment humidity RH 新风 ). The specific functions and processes of the acquisition unit 102 are described in step S220.

[0148] Specifically, in the scheme of the present application, for the air conditioner with fresh air function, a temperature and humidity sensor is arranged at the indoor evaporator (i.e., indoor heat exchanger) and the outdoor condenser (i.e., outdoor heat exchanger) of the air conditioner, respectively. For example, a temperature and humidity sensor (or a temperature sensor and a humidity sensor) is installed at the indoor evaporator side to detect the indoor environment temperature and humidity, and a temperature and humidity sensor is installed at the outdoor condenser side to detect the outdoor environment temperature and humidity. In the scheme of the present application, when the anti-condensation control device for the air conditioner with fresh air function is executed, the fresh air temperature and humidity are the same as the outdoor environment temperature and humidity by default, and the difference ΔT between the fresh air temperature and the indoor environment temperature is defined as fresh air temperature T 室内 -indoor environment temperature T 新风 , and the difference ΔRH between the fresh air humidity and the indoor environment humidity is defined as fresh air humidity RH 室内 -indoor environment humidity RH .

[0149] The control unit 104 is configured to determine the difference between the fresh air temperature of the air conditioner and the indoor environment temperature of the air conditioner, denoted as the fresh air temperature difference of the air conditioner, such as the difference ΔT between the fresh air temperature and the indoor environment temperature T 新风 -indoor environment temperature T 室内 . And determine the difference between the fresh air humidity of the air conditioner and the indoor environment humidity of the air conditioner, denoted as the fresh air humidity difference of the air conditioner, such as the difference ΔRH between the fresh air humidity and the indoor environment humidity RH 新风 -indoor environment humidity RH 室内 . The specific functions and processes of the control unit 104 are described in step S120.

[0150] The control unit 104 is further configured to control the speed of the fresh air motor of the air conditioner, or control the speed of the fresh air motor of the air conditioner and the frequency of the compressor of the air conditioner, based on the preset temperature range and the preset humidity range, according to the fresh air temperature difference of the air conditioner and the fresh air humidity difference of the air conditioner, to achieve the anti-condensation control of the air conditioner. The specific functions and processes of the control unit 104 are also described in step S130.

[0151] Specifically, the anti-condensation control device for the air conditioner with fresh air function proposed in the scheme of the present application comprises:

[0152] Step 1, in the case of air conditioner operation, real-time acquisition of outdoor environment temperature and humidity (i.e. fresh air temperature T 新风 and fresh air humidity RH 新风 ), indoor environment temperature and humidity (i.e. indoor environment temperature T 室内 and indoor environment humidity RH 室内 ), calculation of indoor and outdoor temperature and humidity difference, i.e. difference between fresh air temperature and indoor environment temperature ΔT = fresh air temperature T 新风 - indoor environment temperature T 室内 , difference between fresh air humidity and indoor environment humidity ΔRH = fresh air humidity RH 新风 - indoor environment humidity RH 室内 , and determination.

[0153] Step 2, first determine the current operation mode of the air conditioner. The current operation mode of the air conditioner is any one of the modes of opening fresh air in the air supply mode (hereinafter referred to as strategy A), opening fresh air in the refrigeration mode (hereinafter referred to as strategy B), and opening fresh air in the heating mode (hereinafter referred to as strategy C). Then, in the current operation mode of the air conditioner, according to the range of the difference between the fresh air temperature and the indoor environment temperature ΔT and the difference between the fresh air humidity and the indoor environment humidity ΔRH, the corresponding control of the fresh air motor speed and the compressor operation frequency in the corresponding operation mode is executed to close-loop control the fresh air motor speed and the compressor operation frequency according to the difference between the fresh air temperature and humidity and the indoor temperature and humidity.

[0154] The scheme of the present application proposes a condensation control device for an air conditioner with fresh air function, which closes-loop controls the fresh air motor speed and the compressor operation frequency according to the difference between the fresh air temperature and humidity and the indoor temperature and humidity, achieves the effect of preventing condensation, and solves the problem of condensation of the air conditioner caused by the introduction of fresh air into the indoor environment, which may even cause the air conditioner to blow water, resulting in poor comfort of the air conditioner. In this way, the fresh air motor speed and the compressor operation frequency are adjusted by effective condensation control means to achieve condensation control, improve the comfort of the air conditioner, and improve the user experience.

[0155] In the scheme of the present application, the fresh air motor speed and the compressor operation frequency are subdivided as much as possible according to the temperature and humidity judgment conditions and the judgment difference range to achieve the purpose of more accurate control. In related schemes, whether the condensation condition is met is judged according to the indoor and outdoor environment temperature difference and the indoor environment humidity, and the execution result is only to open or close the fresh air. Alternatively, the first air volume and the second air volume adjusting device opening degree are adjusted according to the indoor environment humidity, the indoor environment temperature, and the fresh air humidity. However, in the scheme of the present application, the condensation control device is judged according to the fresh air temperature, the fresh air humidity, the indoor environment temperature, and the indoor environment humidity, and the execution result is to adjust the fresh air motor speed and the compressor operation frequency.

[0159] Specifically, in different operation modes in the current operation mode of the air conditioner, the preset temperature range and the preset humidity range are different.

[0241] The third heating mode's anti-condensation control scenario when fresh air is turned on: The control unit 104 is specifically configured to, if the temperature difference between the fresh air and the air conditioner's fresh air is less than or equal to the first set temperature, then:

[0242] The control unit 104 is further configured to control the air conditioner's fresh air motor to operate at a reduced speed (fourth set speed) when the fresh air humidity difference of the air conditioner is greater than a fourth set humidity, and to control the air conditioner's compressor to operate at a reduced frequency (first set frequency) when the compressor operates at a reduced frequency (e.g., 400r, first set frequency, e.g., 5Hz).

[0243] The control unit 104 is further configured to, when the difference between the fresh air humidity and the air conditioner's fresh air humidity is greater than a third set humidity and less than or equal to a fourth set humidity, control the air conditioner's fresh air motor to operate at a fifth set speed based on the current speed, and control the air conditioner's compressor to operate at a first set frequency based on the current frequency.

The current speed is the set default speed and the current frequency is the set default frequency.

[0247] Specifically, the anti-condensation control method for an air conditioner with fresh air function proposed in this invention further includes:

[0248] Step 5, when the current operation mode of the air conditioner is heating mode with fresh air, strategy C is executed after the fresh air is opened for 3 minutes, and the fresh air motor speed and the compressor operation frequency are controlled according to the difference ΔT between the fresh air temperature and the indoor environment temperature and the difference ΔRH between the fresh air humidity and the indoor environment humidity. Strategy C is as follows: according to the range of the difference ΔT between the fresh air temperature and the indoor environment temperature and the difference ΔRH between the fresh air humidity and the indoor environment humidity, the control is determined to be executed. Since the compressor is running in the heating mode, the fresh air is opened in the heating mode, and the fresh air motor speed and the compressor operation frequency are controlled. Since the heating mode is opened, in most cases, the outdoor temperature is lower than the indoor temperature, so the temperature of the introduced fresh air is lower than the indoor temperature.

[0249] Step 51, as shown in (c) of Figure 3 Step 51, as shown in (c) of

[0250] ① When the second set temperature is -5℃ < the difference ΔT between the fresh air temperature and the indoor environment temperature, record this condition as condition 1.

[0251] ② When the first set temperature is -10℃ < the difference ΔT between the fresh air temperature and the indoor environment temperature ≤ the second set temperature -5℃, record this condition as condition 2.

[0252] ③ When the difference ΔT between the fresh air temperature and the indoor environment temperature ≤ the first set temperature -10℃, record this condition as condition 3.

[0253] Step 52, according to the difference ΔRH between the fresh air humidity and the indoor environment humidity:

[0254] ① When the fourth set humidity is 30% < the difference ΔRH between the fresh air humidity and the indoor environment humidity, record this condition as condition a.

[0255] ② The third set humidity is 10% < the difference ΔRH between the fresh air humidity and the indoor environment humidity ≤ the fourth set humidity 30%, record this condition as condition b.

[0256] ③ The second set humidity is -10% < the difference ΔRH between the fresh air humidity and the indoor environment humidity ≤ the third set humidity 10%, record this condition as condition c.

[0257] ④ The first set humidity is -30% < the difference ΔRH between the fresh air humidity and the indoor environment humidity ≤ the second set humidity -10%, record this condition as condition d.

[0258] ⑤ The difference ΔRH between the fresh air humidity and the indoor environment humidity ≤ the first set humidity -30%, record this condition as condition e.

[0259] Step 6, after determining the above conditions, the following anti-condensation control is executed, and the new air motor speed and the compressor operating frequency are controlled to achieve more accurate anti-condensation control through the above steps. Figure 4 An action table is executed for all determination results in the anti-condensation control method of the air conditioner with fresh air function of the present application, wherein (a) is an action table executed for all determination results in the case of opening fresh air in the air supply mode, (b) is an action table executed for all determination results in the case of opening fresh air in the cooling mode, and (c) is an action table executed for all determination results in the case of opening fresh air in the heating mode. Similarly, the action table executed for all determination results can be seen from the examples shown in Figure 4

[0260] For example: in the air supply mode with fresh air (A strategy), the third set temperature is, for example, 5℃ < the difference ΔT between the fresh air temperature and the indoor environment temperature (condition 1), the fourth set humidity is, for example, 30% < the difference ΔRH between the fresh air humidity and the indoor environment humidity (condition a), that is, the determination result is A-1-a, and the action of reducing the new air motor speed by 200r is executed.

[0261] The basic principle of the determination of the anti-condensation control in the scheme of the present application is that the greater the indoor and outdoor temperature difference and the greater the difference ΔRH between the fresh air humidity and the indoor environment humidity, the more serious the condensation, and the more the anti-condensation means limits the new air motor speed and the compressor frequency. Since the overall condensation in the air supply mode with fresh air is not as serious as that in the cooling and heating modes with fresh air (in the cooling and heating modes, the user has a requirement for the room temperature, and the indoor temperature will not fluctuate greatly with the action of introducing fresh air; in the air supply mode, the user has no great requirement for the room temperature, and the indoor temperature will fluctuate greatly with the action of introducing fresh air), the control in the air supply mode with fresh air is simpler than that in the cooling and heating modes with fresh air.

[0262] ​The anti-condensation control method provided by the scheme of the present application considers that the temperature and humidity difference between fresh air and indoor environment directly affects condensation, so the temperature difference between fresh air and indoor environment and the humidity difference between fresh air and indoor environment are calculated by collecting outdoor environment temperature (i.e. fresh air temperature), outdoor environment humidity (i.e. fresh air humidity), indoor environment temperature and outdoor environment temperature; the anti-condensation condition is determined according to the range of the temperature difference and the humidity difference, and different anti-condensation controls are performed. The anti-condensation means is to adjust the speed of the fresh air motor and the frequency of the compressor. The control means corresponding to different parameter ranges is subdivided. The anti-condensation control is determined according to the range of the temperature difference and the humidity difference. The division of the temperature difference ΔT between fresh air and indoor environment and the humidity difference ΔRH between fresh air and indoor environment, the control of the speed of the fresh air motor and the control of the frequency of the compressor are only exemplary values to provide a control idea, and are not limited to the exemplary parameter values. Under different temperature differences between fresh air and indoor environment and different humidity differences between fresh air and indoor environment, the condensation of the air conditioner often has great differences. The present application gives corresponding control means by subdividing the condensation under different ranges. The anti-condensation control method is determined by the temperature difference ΔT between fresh air and indoor environment and the humidity difference ΔRH between fresh air and indoor environment, which is more reasonable and solves the condensation problem from the aspect of the condensation formation reason.

[0263] Since the processing and functions realized by the device of the present embodiment basically correspond to the embodiments, principles and examples of the foregoing method, details not described in the description of the present embodiment can be referred to the related description in the foregoing embodiments, which will not be repeated here.
