At the same time, the non-heat exchange air can follow people, avoid people, or oscillate freely.

[0046] Figure 1 This is a schematic flowchart of an air conditioner control method according to an embodiment of the present invention. (Reference) Figures 2 to 6 This invention provides a control method for an air conditioner, which includes two horizontally arranged air outlet columns 10. One of the two air outlet columns 10 can blow out at least a cooling airflow, and the other can blow out at least a non-heat exchange airflow. Figure 1As shown, the control method of the air conditioner in this embodiment includes the following steps:

[0047] Step S1: The control method of the air conditioner includes acquiring the user's location and / or indoor environmental parameters while the two air outlet columns 10 blow out cooling air and non-heat exchange air respectively.

[0048] Step S2: Determine the air outlet direction and / or air outlet speed of each of the two air outlet columns 10 based on the indoor environmental parameters and the user's location.

[0049] When the two air outlet columns 10 blow out cooling air and non-heat exchange air respectively, the air outlet direction and / or air velocity of each of the two air outlet columns 10 can be determined according to indoor environmental parameters and user position. For example, the direction of the cooling airflow can be controlled to avoid people, or the cooling airflow direction can be reduced to a very low speed when the cooling airflow is directed towards people, so as to achieve the effect of the cooling airflow not blowing directly on people and avoid discomfort caused to users by the cooling airflow blowing directly on them. At the same time, the non-heat exchange airflow can follow people, avoid people, or oscillate freely. Especially when it oscillates freely, it can disperse the cooling airflow, which helps to make the temperature of the user space drop evenly and provide users with a better air supply experience.

[0050] Of course, in other embodiments of the present invention, the air outlet direction and / or air outlet speed of the two air outlet columns 10 can also be determined according to indoor environmental parameters.

[0051] In other embodiments of the present invention, the air outlet direction and / or air outlet speed of the two air outlet columns 10 can also be determined according to the user's location.

[0052] Furthermore, in some embodiments of the present invention, step S2 includes directing the cooling airflow away from the user, and causing the non-heat exchange airflow to oscillate or follow the user. Here, avoiding the user can mean either not facing the user, or facing the user but with the air outlet area controlled to face the user's surrounding space, or when facing the user, the speed of the cooling airflow is reduced to a very low level so that the user cannot feel it. When the cooling airflow avoids the user, in order to still provide rapid cooling to the user, the non-heat exchange airflow can oscillate and follow the user. Of course, as mentioned above, in order to make the user space temperature uniform, the non-heat exchange airflow can oscillate and follow the user.

[0053] In some embodiments of the present invention, such as Figure 2 As shown, the user location includes the distance from the user to the air outlet column that blows non-heat exchange airflow. In step S2, the air outlet direction and / or air outlet velocity of each of the two air outlet columns 10 are determined based on indoor environmental parameters and / or the user location, such as... Figure 2 As shown, it includes the following steps:

[0054] Step S21: Determine the wind speed of the non-heat exchange airflow based on the distance. The distance includes at least a first distance and a second distance, where the value of the first distance is less than the value of the second distance. The wind speed of the non-heat exchange airflow determined based on the first distance is less than the wind speed of the non-heat exchange airflow determined based on the second distance.

[0055] Since non-heat exchange airflow does not cause discomfort to pregnant women, children, or elderly people with rheumatism, providing a good user experience, it can be directed towards the user. Simultaneously, to ensure the non-heat exchange airflow reaches the user at a suitable speed—for example, 0.5 m / s—so the user can feel the breeze without it being too strong, the distance from the user to the outlet column 10 of the non-heat exchange airflow can be determined. As the distance increases, the airflow speed also increases to ensure the user receives the same ambient temperature airflow at the same speed. Here, the airflow speed can increase proportionally with the distance, or the distance can be divided into multiple distance segments, each corresponding to a different airflow speed, with longer distance segments corresponding to higher airflow speeds.

[0056] Furthermore, in some embodiments of the present invention, the distance from the user to the outlet column 10 that blows non-heat exchange airflow can be divided into multiple distance segments. For example, 0 to 1 meter is the first distance segment, and the first distance can be within this segment; 1 to 2 meters is the second distance segment, and the second distance can be within this segment; 2 to 3 meters is the third distance segment; 3 to 4 meters is the fourth distance segment; and more than 4 meters is the fifth distance segment. Different distance segments correspond to different wind speeds, and the wind speed increases as the distance segment value increases, so that the wind speed blowing on the user remains approximately constant.

[0057] In some embodiments of the present invention, there are multiple users at different distances, and the wind speed can be adjusted according to these different distances. In other embodiments of the present invention, there is only one user, but the user may move within the room, and the wind speed can be adjusted according to the changes in distance caused by this user's movement.

[0058] In some embodiments of the present invention, the distance from the user to the air outlet column 10 that blows non-heat exchange airflow can be measured by a radar installed on the indoor unit of the air conditioner.

[0059] In some embodiments of the present invention, the indoor environmental parameters include at least the indoor ambient temperature. In step S2, the airflow direction and / or airflow velocity of each of the two air outlet columns 10 are determined based on the indoor environmental parameters and / or the user's location, such as... Figure 3 As shown, it includes the following steps:

[0060] Step S22: Obtain the difference between the indoor ambient temperature and the set temperature.

[0061] Step S23: Determine the wind speed of the cooling airflow and the wind speed of the non-heat exchange airflow based on the difference. The difference includes at least a first difference and a second difference. The first difference is less than the second difference. The wind speed of the cooling airflow and the wind speed of the non-heat exchange airflow determined based on the first difference are respectively less than the wind speed of the cooling airflow and the wind speed of the non-heat exchange airflow determined based on the second difference.

[0062] In these embodiments, the presence of a difference indicates that the cooling capacity brought by the cooling airflow is insufficient to lower the indoor temperature. The larger the difference, the more cooling capacity is required, the more cooling airflow is needed, and the higher the wind speed of the cooling airflow is required. At the same time, in order to accelerate the uniform diffusion of the cooling airflow into the indoor space, the wind speed of the non-heat exchange airflow is also higher. Moreover, reducing the difference is the most important thing to reduce the indoor ambient temperature as quickly as possible. Therefore, the wind speed increase rate of the cooling airflow is higher than that of the non-heat exchange airflow.

[0063] Furthermore, in some embodiments of the present invention, when the first difference is within a small difference range, the wind speed of the non-heat exchange airflow is a first velocity, and the wind speed of the cooling airflow has at least a second velocity and a third velocity, where the second velocity is less than the first velocity and the third velocity is greater than the second velocity. When the second difference is within a large difference range, the wind speed of the non-heat exchange airflow is a fourth velocity, where the fourth velocity is greater than the first velocity, and the wind speed of the cooling airflow has at least a fifth velocity and a sixth velocity, where the fifth velocity is equal to the fourth velocity and the sixth velocity is greater than the fifth velocity. For example, when the first difference is within a small difference range of 0 to 3°C: when the difference is less than or equal to zero, the wind speed of the cooling airflow is low, and the wind speed of the non-heat exchange airflow is medium. When the difference is greater than zero and less than or equal to 3°C, the wind speed of the cooling airflow is medium, and the wind speed of the non-heat exchange airflow is medium. When the second difference is within a large difference range greater than 3°C: when the difference is greater than 3°C and less than or equal to 5°C, the wind speed of the cooling airflow is high, and the wind speed of the non-heat exchange airflow is high. When the temperature difference is greater than 5°C, the airflow speed of the cooling air is ultra-high, and the airflow speed of the non-heat exchange air is high.

[0064] In some embodiments of the present invention, such as Figure 4 As shown, based on the set temperature and the temperature compensation value, the first target temperature is obtained. The first target temperature is the sum of the set temperature and the temperature compensation value, where the temperature compensation value is positive. The control method of the air conditioner includes the following steps:

[0065] Step S6: After the indoor ambient temperature drops to the first target temperature, the two air outlet columns blow out cooling air and non-heat exchange air respectively. That is, after the temperature drops to the first target temperature, uniform airflow can be used to make the user feel comfortable and maintain a constant indoor temperature for a longer period of time.

[0066] In some embodiments of the present invention, the first target temperature is less than or equal to a preset value. For users who are not afraid of the cold, such as young people, since the first target temperature is already relatively low, it is necessary to blow mixed air to prevent health problems caused by the set temperature being too low in order to ensure the user's health. Of course, if the user sets a temperature higher than the preset value, it is not necessary to blow mixed air; the air conditioner can operate normally, with both air outlets cooling.

[0067] In some embodiments, the temperature compensation value can be from 0.5°C to 1.5°C, preferably 1°C. The preset temperature can be from 18°C ​​to 22°C, preferably 20°C. That is, when the indoor ambient temperature is already relatively low and close to the set temperature, one air outlet column 10 is controlled to blow a cooling airflow to provide cooling to maintain the indoor temperature. The other air outlet column 10 blows a non-heat exchange airflow to accelerate the uniform mixing of indoor air.

[0068] In some embodiments of the present invention, such as Figure 5 As shown, the control method for the air conditioner includes the following steps:

[0069] Step S7: When the two air outlet columns 10 blow out cooling air and non-heat exchange air respectively, the indoor ambient temperature is obtained after a preset running time period.

[0070] Step S8: Determine whether the two air outlet columns 10 blow out cooling air or non-heat exchange air based on the indoor ambient temperature.

[0071] Furthermore, in some embodiments of the present invention, a second target temperature is obtained based on a set temperature and a temperature compensation value, wherein the second target temperature is the difference between the set temperature and the temperature compensation value. Step 8 includes:

[0072] When the indoor ambient temperature is greater than or equal to the second target temperature and less than the first target temperature, continue or make the two air outlet columns 10 blow out cooling air and non-heat exchange air respectively.

[0073] When the indoor ambient temperature is greater than or equal to the first target temperature, both air outlet columns 10 will blow out cooling airflow.

[0074] When the indoor ambient temperature is lower than the second target temperature, the two air outlet columns 10 will stop operating.

[0075] In other words, when one air outlet column 10 blows cooling air and the other air outlet column 10 blows non-heat exchange air, if the indoor ambient temperature fluctuates within a suitable range, the air outlet state of the two air outlet columns 10 will remain unchanged. If the indoor ambient temperature rises above a certain level, both air outlet columns 10 will blow cooling air to lower the temperature. If the indoor temperature drops to a relatively low level, both air outlet columns 10 will stop operating and cease blowing air.

[0076] In some embodiments of the present invention, indoor environmental parameters include indoor humidity. The airflow direction and / or airflow velocity of each of the two air outlet columns 10 are determined based on the indoor environmental parameters and / or the user's location, including determining the wind speed of the cooling airflow and the wind speed of the non-heat exchange airflow based on the indoor humidity. The humidity difference between the indoor humidity and the set humidity includes at least a first humidity difference and a second humidity difference, where the first humidity difference is less than the second humidity difference. The wind speed of the cooling airflow is determined as a seventh velocity and the wind speed of the non-heat exchange airflow as an eighth velocity based on the first humidity difference. The wind speed of the cooling airflow is determined as a ninth velocity and the wind speed of the non-heat exchange airflow as a tenth velocity based on the second humidity difference. The seventh velocity is greater than the ninth velocity. The eighth velocity is less than the tenth velocity.

[0077] When the airflow velocity of the cooling air is low, the evaporator temperature is low, resulting in good condensation and dehumidification. However, the reduced airflow velocity also decreases indoor air circulation, hindering dehumidification. When one air outlet column 10 cools and dehumidifies, while another outlet column 10 blows out non-heat exchange air, dehumidification and accelerated indoor air circulation can be achieved simultaneously, enhancing the dehumidification effect. In some embodiments, the airflow velocity of the cooling air and the non-heat exchange air can be determined based on humidity difference ranges. For example, the first humidity difference range can be less than 10%, the second humidity difference range can be 10% to 20%, the third humidity difference range can be 20% to 30%, and the fourth humidity difference range can be greater than 30%. Each humidity difference range corresponds to a different airflow velocity of the cooling air and the non-heat exchange air. As the humidity difference range decreases, the airflow velocity of the corresponding cooling air increases, and the airflow velocity of the corresponding non-heat exchange air decreases.

[0078] In some embodiments of the present invention, such as Figure 6 As shown, two air outlet columns 10 are spaced apart to form an air intake interval 20. When the two air outlet columns 10 blow out airflow, the air in the air intake interval 20 is blown forward and mixed with the airflow blown out by the two air outlet columns 10. When both air outlet columns 10 blow out cool airflow, the cool airflow mixes with the indoor air in the air intake interval 20, so that the temperature of the blown airflow is not low and it is not harsh on the user.

[0079] In some embodiments of the present invention, each air outlet column 10 includes an air duct and a heat exchanger. The heat exchanger is disposed within the air duct. A working fluid flow path is provided within the heat exchanger, and two working fluid flow paths are arranged in parallel. The air conditioner also includes a three-way control valve, with its two ports respectively connected to the two working fluid flow paths, to controllably enable the two heat exchangers to operate simultaneously or only one heat exchanger to operate. When the air conditioner is operating, the three-way control valve controls the working state of the heat exchangers by controlling the working fluid flow paths. The three-way control valve can control the two heat exchangers to operate simultaneously or only one of them to operate, thereby enabling the two air outlets to have multiple air outlet modes. For example, both air outlets can simultaneously blow out heat exchange airflow, or one air outlet can blow out heat exchange airflow while the other blows out non-heat exchange airflow. The heat exchange airflow and non-heat exchange airflow can be mixed or blown separately to their respective designated areas. Mixed airflow can make the airflow temperature close to room temperature, avoiding discomfort caused by heat exchange airflow directly blowing onto the user. Multiple air outlet modes can meet various air usage needs of users.

[0080] In some embodiments of the present invention, each air outlet column 10 includes at least one vertical strip-shaped air outlet 12. Each air outlet column 10 is rotatably disposed, or each air outlet 12 is provided with an air guide device 18 for controlling the lateral air outlet direction of the air outlet 12.

[0081] This invention also provides an air conditioner, including a control device. The control device includes a memory and a processor. The memory stores a control program, which, when executed by the processor, is used to implement the control method of the air conditioner as described in any of the above embodiments.

[0082] Therefore, those skilled in the art should recognize that although numerous exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Thus, the scope of the present invention should be understood and construed as covering all such other variations or modifications.
