Adjust the distance between the two sides of the wall: When the air conditioner is at the same distance from the left wall and the right wall, adjust the left air supply angle of the air conditioner to be equal to the right air supply angle; when the air conditioner is closer to the right wall than the left wall Adjusting the air supply angle to the left is smaller than the right air supply angle; when the air conditioner is farther from the left wall than the right wall, the air supply angle of the air conditioner to the left is larger than the right air supply angle.

Detailed ways

The invention will be described in detail below with reference to the drawings and specific embodiments.

Air conditioner air supply method, according to air conditioner installation position, room structure, air conditioner itself Shape, adjust the air supply angle and the left and right direction air supply time. The air supply angle includes the air supply angle of the air conditioner in the up and down direction and the air supply angle in the left and right direction.

Y is the distance between the wall where the air conditioner is located and the opposite wall, p is the depth of the air conditioner, b is the distance from the center of the air conditioner to the ground; H is the height from the ground when the airflow of the air conditioner can reach the highest point of the opposite wall, L is the air conditioner The point at which the airflow is projected on the ground when the airflow reaches the closest point on the ground.

Please refer to Figure 1 and Figure 2. 1 is a side view of the air conditioner installation in the present invention, where Y is the distance between the wall where the air conditioner is located and the opposite wall, p is the depth of the air conditioner, b is the distance from the center of the air conditioner to the ground; H is the airflow of the air conditioner The height of the point from the ground at the highest point of the opposite wall, L is the distance from the air conditioner at the ground when the air conditioning airflow can reach the nearest point of the ground. The values of H and L are the target parameters involved in the present invention, and are determined according to factors such as the capacity of the air conditioner (corresponding to the size of the installation space), the characteristics of the hot and cold air, and the comfort of the human body in the air conditioning design process; Normally, the cold air sinks and the hot air floats. The human comfort is mainly sensitive to the human body's reaction to head air temperature changes. Corresponding to the different operating modes of the air conditioners such as cooling and heating, different H and L are given to make the room temperature reach the user set temperature faster under the premise of satisfying the human body comfort. Calculate the corresponding up and down air supply angle according to the following formula:

The two parameters, Η and L, belong to the set target parameters of the design phase.

Example: We briefly explain the design method by installing 1P air conditioner in 4m*4m*3m room. The installation height of air conditioner is 2.5m and the thickness of air conditioner is 0.2m. In the cooling state: Considering the sinking characteristics of the cold air, the main air supply area concentrates a higher space. For example: 3π! ~ 1.5m height, at the same time, to ensure that most of the room area above 1.2m can feel the cool breeze. Based on the above data, it can be inferred that H = 3m and L = 3.4 - 0.2 = 3.2m.

In the heating state: Considering the rising characteristics of the hot air, the main air supply area is concentrated in a lower space, for example: 2m~lm height, and at the same time, the warm air can be better felt in most areas of the room below 2m. Based on the above data, it can be inferred that H = 1.8m, L two 1.2-0.2 = lm.

2 is a top view of the air conditioner installation in the present invention, where X and Y are respectively the length and width of the room, wherein the value of Y is the distance between the wall of the air conditioner and the opposite wall, "the distance from the center of the air conditioner to the left wall, S left and S right respectively indicate the dead angle area that the airflow does not need to reach when sweeping the air to the left and right, and respectively indicate the air supply angle in the left and right directions. The total area of the room is S total (=X*Y), and the air conditioner is air conditioner. The blind angle ratio parameter when sweeping the wind left and right, specifically the area ratio of the dead space that the airflow cannot reach, is the ratio of the area of the whole room, that is, N=(S left+S right)/S total, and the value of Ν is given. The equations calculate the left and right air supply angles,

The left and right direction of the air supply angle is about ^.

The initial parameters required - the structural size of the room, the structural size of the air conditioner itself, and the relative size of the air conditioning installation location, can be obtained by intelligent sensing or manual measurement of the air conditioner; intelligent sensing is performed by setting the smart in the air conditioner. Inductive devices (such as infrared scanning devices, etc.) automatically scan initial parameters such as the size of the room structure and the relative position of the air conditioner installation; the manual measurement method determines the corresponding initial parameters by means of on-site measurement.

The air supply angle is controlled by the sweeping motor, and the control of the sweeping motor can be realized by continuous precise control mode, direct dialing control mode, and remote dialing control mode. Among them, the dialing method refers to designing several sets of different sweep angle combinations according to the conventional air conditioner installation position, and coding correspondingly. In the control system, only the selection of the code is selected to complete different sweep angle selection. You can choose to dial directly on the main board, remote dialing, etc.

The continuous precision control mode is mainly related to the dialing mode, and refers to the full intelligent control mode. Control program Based on the initial conditions of the sensed or manual input, the above calculation formula is used to calculate the sweep angle in each direction to achieve a sweep pattern that fully conforms to the current installation mode. '

The following is an example of direct dialing control.

For F-26G-capable air conditioners, it is assumed that the room usage area is 16 square meters, and the length*width size is 4m*4m. When the air conditioner is installed, four position ranges are set, -^α≤1, Κα≤2, 2<α≤ 3,3<α≤4 ( _α indicates the distance from the air conditioning center to the left wall), and the four ranges are set to four gear positions. "≤1 gear 1, 1 <" ≤ ² ₂ speed, ² <a≤ ³ ₃ shift, ³ <"≤ ⁴ for the fourth speed. When the air conditioner installed in the client 1.5m distance from the left wall, At this time, 1<α≤ ² , 2 gears should be selected. When the air conditioners of different customers are installed in the corresponding four different positions of the room, the air conditioners respectively select different gear positions to control the appropriate azimuth of the airflow, so that Achieve comfortable airflow organization and improve air conditioner efficiency.

The above embodiments are merely illustrative and not limiting of the technical solutions of the present invention. Any modifications or partial substitutions of the present invention are intended to be included within the scope of the appended claims.
