Description

[0002] Parts of my country are cold and wet in winter, and traditional air conditioning dehumidification needs to be carried out under refrigeration conditions, which greatly affects the user experience. In a cold and wet environment, the heat exchange part of the air conditioner is prone to emit an unpleasant odor when heating, which not only affects the user's comfort experience, but also damages the user's health. Based on this phenomenon, the air conditioner in the prior art uses a cold plasma generator. The plasma discharge generated by the operation of the cold ion generator causes the released negative ions to react with water, oxygen, etc. in the air to form ozone and hydrogen peroxide that can kill bacteria, thereby achieving the purpose of sterilizing the airflow. The temperature and humidity of the air will affect the concentration of negative ions released by the cold plasma generator, which in turn affects the sterilization and deodorization effect. In particular, during the dehumidification process of the air conditioner, the humidity of the air is low, which greatly reduces the sterilization and deodorization effect. Summary of the invention

[0003] Therefore, the present invention provides a constant temperature dehumidification air conditioner control method and control device, storage medium and air conditioner, which can solve the technical problem that the air conditioner with a cold plasma generator in the prior art has poor plasma sterilization and deodorization effect.

On the one hand, the moisture in the air can be condensed and retained on the heat exchanger, so that the outer side of the heat exchanger and other components can be in a water-wrapped state, and there is no need to humidify the corresponding components inside the air conditioner separately.

[0036] See also Figure 1 to Figure 2 As shown, according to an embodiment of the present invention, a constant temperature dehumidification air conditioner control method is provided. As a specific implementation method, the aforementioned constant temperature dehumidification air conditioner specifically includes a shell, a heat exchanger arranged in the shell, and an indoor fan arranged corresponding to the heat exchanger. The shell is constructed with an air inlet and an air outlet, wherein the air inlet is provided with an air inlet grille, the air inlet grille has an air inlet state and a closed state, the air outlet is provided with an air guide plate, the air guide plate has an air outlet state and a closed state, and a cold plasma generator is also provided in the shell, which can sterilize and deodorize the heat exchanger.

[0037] See also Figure 2As shown, the aforementioned heat exchanger specifically includes at least two folded heat exchange parts, such as a first heat exchange part 11 and a second heat exchange part 12, wherein the refrigerant outlet pipe of the first heat exchange part 11 is connected in series with the refrigerant inlet pipe of the second heat exchange part 12 through a throttling element 2, thereby achieving a higher refrigerant temperature in the first heat exchange part 11 than in the second heat exchange part 12. In this way, the temperature of the incoming air flow after heat exchange through the first heat exchange part 11 will also be higher than the temperature of the incoming air flow after heat exchange through the second heat exchange part 12. The two incoming air flows of high and low temperatures are mixed and the temperature is balanced before flowing out from the same air outlet, achieving the effect of constant air temperature. At the same time, the moisture in the incoming air flow at the second heat exchange part 12 is condensed and precipitated, that is, the effect of dehumidification of the air outlet is achieved. Of course, in some embodiments, the heat exchanger may also include a third heat exchange part 13, which may be arranged in series with one side of the refrigerant inlet pipe of the first heat exchange part 11 to increase the heating area. Figure 2 Taking the heat exchanger shown in as an example, it has three folds, which are the first fold heat exchange part (also the third heat exchange part 13 mentioned above), the second fold heat exchange part (also the first heat exchange part 11 mentioned above) and the third fold heat exchange part (also the second heat exchange part 12 mentioned above) from left to right in the figure. After the refrigerant enters the first fold heat exchange part, it flows through 4 U-tubes and then is divided into two paths to flow into the second fold heat exchange part. The two refrigerants each flow into the solenoid valve (also the throttling element 2 mentioned above) through three U-tubes, and then are divided into two paths after the valve to flow into the third fold heat exchange part, and each flows out after three U-tubes. The present invention uses a solenoid valve for throttling. In the constant temperature dehumidification, the part before the valve is the high temperature part, and the part after the valve is the low temperature part. By controlling the amount of cold and heat in the cooling and heating parts, the constant temperature is finally achieved by comprehensive offset.

[0038] See Figure 1 As shown, the constant temperature dehumidification air conditioner control method includes the following steps:

[0039] The real-time humidity φ of the indoor environment is obtained by a temperature and humidity sensor arranged on the outside of the shell; the relationship between the real-time humidity φ and a first preset humidity a is determined, and the first preset humidity a can be set by the user according to personal preference; when φ>a, it means that the air humidity of the indoor environment is relatively large, and the air conditioner is controlled to operate in a constant temperature dehumidification mode; during the operation of the constant temperature dehumidification mode, the temperature and humidity sensor detects and obtains the real-time humidity φ in real time, and when φ<b, it means that the humidity of the indoor environment is already at a level that is relatively comfortable for the user, and the cold plasma generator in the air conditioner is controlled to operate, and the aforementioned b is a second preset humidity, which is less than a and can be set by the user according to personal preference.

[0040] In this technical solution, the indoor environment is first dehumidified at a constant temperature before controlling the operation of the cold plasma generator. In this way, on the one hand, the moisture in the air can be condensed and retained on the heat exchanger, so that the outside of the heat exchanger and other components can be wrapped in water, and there is no need to humidify the corresponding components inside the air conditioner separately. When the cold plasma generator is operated in this state, the negative ion concentration is higher and has a better sterilization and deodorization effect. On the other hand, since it is in a constant temperature state, the temperature around the heat exchanger in the air conditioner is maintained at a higher temperature rather than a lower temperature. Running the cold plasma generator at a higher temperature can also have a better sterilization and deodorization effect, thereby preventing the occurrence of heating odor when the air conditioner is heating, and can improve the comfort of the air-conditioned room.

[0041] In some embodiments, before the cold plasma generator is controlled to operate, and when φ<b, the air guide plate and air inlet grille of the air conditioner are controlled to be in a closed state, that is, the cold plasma generator operates in a relatively closed space in the air conditioner, which can effectively prevent the dehumidified airflow outside the air conditioner from entering the air conditioner, causing the generated negative ions to neutralize the static electricity in the dry air, thereby reducing the sterilization and deodorization effect. In a preferred embodiment, after the air guide plate and the air inlet are both in a closed state, the air conditioner is controlled to operate in a heating mode, and the temperature in the air conditioner can be further increased by operating in the heating mode, further improving the sterilization and deodorization effect.

[0042] As a preferred embodiment, after the plasma generator runs for a preset time (specifically set by the user, such as 5 minutes), the air guide plate and the air inlet grille of the air conditioner are controlled to be in an open state so as to be able to continue subsequent control modes, such as the air conditioner further running in heating mode, which can facilitate drying inside the air conditioner.

[0043] After the air guide plate and the air inlet are both in a closed state, the indoor fan of the air conditioner is controlled to run at a low speed. Controlling the indoor fan to run at a relatively low speed can, on the one hand, drive the airflow inside the air conditioner to circulate internally, thereby making the internal temperature and humidity more uniform and fully in contact with negative ions, thereby achieving the purpose of optimizing sterilization and deodorization, and on the other hand, it can reduce the operating energy consumption of the air conditioner. The aforementioned low-speed operation of the indoor fan is specifically compared with the wind speed in the normal heating mode or cooling mode of the air conditioner. For example, if there is a minimum wind speed in both the heating mode and the cooling mode, the low-speed operation of the indoor fan refers to running at a wind speed lower than the minimum wind speed. The specific speed value is related to the model and type of the air conditioner, and the present invention does not limit it.

[0044] The technical solution of the present invention is further described below in conjunction with a preferred embodiment of the present invention:

[0045] like Figure 3As shown, assuming that the environment is a humid and cold environment, sterilization and constant temperature dehumidification are required at the same time:

[0046] The air conditioner is turned on and is in heating mode. The temperature and humidity sensor detects the indoor temperature and humidity. Let the temperature be T, the humidity before dehumidification be φ1, and the humidity after dehumidification be φ2.

[0047] When humidity φ1>a is detected, the constant temperature dehumidification mode is started. At this time, the temperature of the third fold (i.e., the second heat exchange part 12) of the indoor unit evaporator (i.e., the heat exchanger mentioned above, the same below) is low, so that condensed water is precipitated after the indoor air reaches the dew point, the air humidity is reduced, and condensed water is attached to the evaporator. After the constant temperature dehumidification runs for a period of time, the humidity φ2<b is detected, and the constant temperature dehumidification stops (a and b are both set humidity constants).

[0048] After the constant temperature dehumidification stops, close the air guide plate and the air inlet grille to create a relatively closed environment inside the air conditioner. Turn on the heating mode and control the crossflow fan blades (that is, the indoor fan mentioned above) to run at a low speed, so that the temperature and humidity inside the air conditioner are relatively high, which can effectively prevent the negative ions released by the cold plasma generator from being neutralized by static electricity.

[0049] Start the cold plasma generator, and through plasma discharge, the negative ions released react with water, oxygen, etc. in the air to form ozone and hydrogen peroxide that can kill bacteria, and sterilize and deodorize the inside of the air conditioner. After the sterilization and deodorization is completed, open the air guide plate and the air inlet grille, and the air conditioner will run normally.

[0050] According to an embodiment of the present invention, there is also provided a constant temperature dehumidification air conditioner control device, comprising:

[0051] An acquisition module is used to acquire the real-time humidity φ of the indoor environment, specifically through a temperature and humidity sensor arranged on the outside of the shell; a judgment execution module is used to: judge the relationship between the real-time humidity φ and a first preset humidity a, and the first preset humidity a can be set by the user according to personal preference; when φ>a, it means that the air humidity of the indoor environment is relatively large, and the air conditioner is controlled to operate in a constant temperature dehumidification mode; during the operation of the constant temperature dehumidification mode, the temperature and humidity sensor detects and acquires the real-time humidity φ in real time, and when φ<b, it means that the humidity of the indoor environment is already at a level that the user is relatively comfortable with, and the cold plasma generator in the air conditioner is controlled to operate, and the aforementioned b is a second preset humidity, which is less than a and can be set by the user according to personal preference.

[0052] In this technical solution, the indoor environment is first dehumidified at a constant temperature before controlling the operation of the cold plasma generator. In this way, on the one hand, the moisture in the air can be condensed and retained on the heat exchanger, so that the outside of the heat exchanger and other components can be wrapped in water, and there is no need to humidify the corresponding components inside the air conditioner separately. When the cold plasma generator is operated in this state, the negative ion concentration is higher and has a better sterilization and deodorization effect. On the other hand, since it is in a constant temperature state, the temperature around the heat exchanger in the air conditioner is maintained at a higher temperature rather than a lower temperature. Running the cold plasma generator at a higher temperature can also have a better sterilization and deodorization effect, thereby preventing the occurrence of heating odor when the air conditioner is heating, and can improve the comfort of the air-conditioned room.

[0053] In some embodiments, the judgment execution module is also used to: before controlling the operation of the cold plasma generator, and when φ<b, control the air guide plate and air inlet grille of the air conditioner to be in a closed state, that is, the cold plasma generator is operated in a relatively closed space in the air conditioner, which can effectively prevent the dehumidified airflow outside the air conditioner from entering the air conditioner, resulting in the negative ions generated being neutralized with the static electricity in the dry air, thereby reducing the sterilization and deodorization effect. In a preferred embodiment, after the air guide plate and the air inlet are both in a closed state, the air conditioner is controlled to operate in a heating mode, and the temperature in the air conditioner can be further increased by operating in the heating mode, further improving the sterilization and deodorization effect.

[0054] In some embodiments, the judgment execution module is also used to: after the plasma generator runs for a preset time (specifically set by the user, such as 5 minutes), control the air guide plate and the air inlet grille of the air conditioner to be in an open state, so as to be able to continue the subsequent control mode, such as the air conditioner further running the heating mode, which can be beneficial to the drying of the air conditioner.

[0055] In some embodiments, the judgment execution module is also used to: after the air guide plate and the air inlet are both in a closed state, control the indoor fan of the air conditioner to run at a low speed. Controlling the indoor fan to run at a lower speed can, on the one hand, drive the airflow inside the air conditioner to circulate internally, so that the internal temperature and humidity are more uniform and fully in contact with negative ions, thereby achieving the purpose of optimizing sterilization and deodorization, and on the other hand, it can reduce the operating energy consumption of the air conditioner. The aforementioned low-speed operation of the indoor fan is specifically compared with the wind speed in the normal heating mode or cooling mode of the air conditioner. For example, if there is a minimum wind speed in both the heating mode and the cooling mode, the low-speed operation of the indoor fan refers to running at a wind speed lower than the minimum wind speed. The specific speed value is related to the model and type of the air conditioner, and the present invention does not limit it.

[0056] According to an embodiment of the present invention, there is further provided a storage medium on which a computer program is stored, and the program implements the steps of the above method when executed by a processor.

[0057] According to an embodiment of the present invention, there is also provided an air conditioner, comprising the control device as described above.

[0058] It is easy for those skilled in the art to understand that, without conflict, the advantageous technical features of the above-mentioned methods can be freely combined and superimposed.

[0059] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention. The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present invention, and these improvements and variations should also be regarded as the protection scope of the present invention.
