Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and particularly relates to a control method for an air-conditioning air-sweeping assembly. Background Art

[0002] In the design of the air duct of a cabinet air conditioner, the internal layout of the air conditioner is compact, the electrical box and pipeline structure are complex, and the air flow organization is chaotic. At present, the air outlet is mainly controlled by relying on the guiding effect of an intermediate bracket (partition plate) on the air flow. The intermediate bracket (partition plate) usually adopts a bending process, and the structural form is simple, and the guiding effect on the air flow is poor. As a result, there are technical problems that there is no wind in some local areas on the surface of the air-conditioning evaporator, and the wind speed on the surface of the evaporator is uneven.

[0003] Due to the technical problems such as no wind in some local areas on the surface of the air-conditioning evaporator and uneven wind speed on the surface of the evaporator in the prior art, the present invention researches and designs a control method for an air-conditioning air-sweeping assembly. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the wind speed on the surface of the air-conditioning evaporator in the prior art is uneven, so as to provide a control method for an air-conditioning air-sweeping assembly.

[0005] To solve the above problems, the present invention provides a control method for an air-conditioning air-sweeping assembly, which includes:

[0006] A detection step of detecting the wind speeds of multiple regions on the surface of the evaporator when the air-sweeping assembly is at a preset angle, and detecting the wind speeds of multiple regions on the surface of the evaporator when the air-sweeping assembly is at multiple different angles;

[0007] A calculation step of obtaining the air volume of a region by multiplying the wind speed at the preset angle by the duration at that angle; calculating the sum of the air volumes at multiple different angles in the region within one cycle to obtain the air volume of the region within one cycle; making the air volumes between different regions within one cycle equal to each other, so as to obtain the duration of staying at different angles; and obtaining the rotational angular velocity of the air-sweeping assembly according to different angles and their corresponding durations.

[0008] In some embodiments, in the detection step, the wind speed distribution on the surface of the evaporator when the air-sweeping plate is at a certain angle is measured according to the test or simulation calculation result, measured at a specified position on the surface of the evaporator by an anemometer, and the wind speed value is extracted through fluid simulation.

[0009] In some embodiments, the relational expression for calculating the sum of the air volumes at multiple different angles in the region within one cycle is:

[0010] Q n =3600*Sn*(V 10n *T1 +V 20n *T 2 +V 30n *T 3 +V 40n *T 4 +……+V m0n *T m )

[0011] Q n is the air volume of area n, S n is the preset area of area n, V 10n ~V m0n is the average wind speed at area n when the angle changes from angle 1 to angle m, T 1 ~T m is the time when the wind sweeping board is at angles 1 to m respectively, where both n and m are natural numbers, and n≥4, m≥4.

[0012] In some embodiments, the relationship for making the air volumes between different areas equal within one cycle is:

[0013] Q 1 =Q 2 =……Q n , that is, 3600*S1*(V 101 *T 1 +V 201 *T 2 +V 301 *T 3 +V 401 *T 4 +……

[0014] +V m01 *T m )=3600*S2*(V 102 *T 1 +V 202 *T 2 +V 302 *T 3 +V 402 *T 4 +……+V m02 *T m )……=3600*Sn*(V 10n *T 1 +V 20n *T 2 +V 30n *T 3 +V 40n *T 4 +……+V m0n *T m ), thereby obtaining T 1 , T2 ……T m 。

[0015] In some embodiments, the calculation of the air volume in each area within one movement cycle of the evaporator surface is simplified and defined as:

[0016] Q i = v ij *T j

[0017] where i is the area number and j is the angle number, and there is Q 1 = Q 2 = ……Q i = ……Q n , 1 ≤ i ≤ n, 1 ≤ j ≤ m.

[0018] In some embodiments, the angle F(T) is fitted with time T, and it is obtained that: F(T) = p1*T^3 + p2*T^2 + p3*T + p4, where p1, p2, p3, and p4 are all coefficients;

[0019] Then the angular velocity of the movement of the air deflector is F 1 (T) = 3p1*T^2 + 2p2*T + p3.

[0020] In some embodiments, the variable-speed movement of the air deflector is controlled by separately controlling the values of p1, p2, and p3.

[0021] In some embodiments, fluid simulation is performed for four movement angles of the air deflector at 0°, 30°, 60°, and 90°, then m = 4, T 1 , T 2 , T 3 and T 4 are the times when the air deflector is at angles 1 to 4 respectively, angle 1 = 0°, angle 2 = 30°, angle 3 = 60°, angle 4 = 90°.

[0022] In some embodiments, the wind speed distribution of multiple areas on the surface of the evaporator is statistically analyzed by dividing it into multiple areas according to the height of the evaporator, and the average wind speed is taken for each cross-section.

[0023] In some embodiments, the height of the evaporator of the air conditioner is L, which is vertically equally divided into n areas, and the average wind speed value is extracted for each area to calculate the air volume of that area, so as to control the wind speed of different areas according to different evaporator heights and different angles of the air deflector.

[0024] A control method for an air deflector assembly of an air conditioner provided by the present invention has the following beneficial effects:

[0025] The present invention designs a method for calculating the movement speed of the sweep plate according to the wind speed distribution of the evaporator corresponding to the angle of the sweep plate, so as to guide the air outlet direction, adjust the air volume and evenly discharge the air; the wind speed distribution on the surface of the evaporator when the sweep plate is at a certain angle is obtained according to experimental or simulation calculations, and the length of time the sweep plate stays at the angle is calculated, so that the air volume passing through each area of ​​the evaporator surface within one movement cycle of the sweep plate (the air volume passing through the area = the calculated wind speed at that location * the area of ​​the area * the movement cycle) is approximately equal, thereby improving the air volume distribution on the evaporator surface, making the wind speed passing through each part of the evaporator surface as uniform as possible, and improving the heat transfer efficiency of the evaporator.

[0033] like Figures 1-5 As shown, the present invention provides a control method for an air-conditioning air sweeping component, which comprises:

[0034] a detection step of detecting wind speeds of multiple areas of the evaporator surface when the wind sweep assembly is at a preset angle, and detecting wind speeds of multiple areas of the evaporator surface when the wind sweep assembly is at multiple different angles;

[0035] The calculation steps are as follows: the wind volume of the area is obtained by multiplying the wind speed at a preset angle by the duration at the angle; and the sum of the wind volumes at multiple different angles in the area within a cycle is calculated to obtain the wind volume of the area within a cycle; the wind volumes of different areas are made equal to each other within a cycle, so as to calculate the duration at different angles; and the rotational angular velocity of the wind sweeping component is obtained according to the different angles and their corresponding durations.

[0036] The present invention designs a method for calculating the movement speed of the sweep plate according to the wind speed distribution of the evaporator corresponding to the angle of the sweep plate, so as to guide the air outlet direction, adjust the air volume and evenly discharge the air; the wind speed distribution on the surface of the evaporator when the sweep plate is at a certain angle is obtained according to experimental or simulation calculations, and the length of time the sweep plate stays at the angle is calculated, so that the air volume passing through each area of ​​the evaporator surface within one movement cycle of the sweep plate (the air volume passing through the area = the calculated wind speed at that location * the area of ​​the area * the movement cycle) is approximately equal, thereby improving the air volume distribution on the evaporator surface, making the wind speed passing through each part of the evaporator surface as uniform as possible, and improving the heat transfer efficiency of the evaporator.

[0037] The present invention proposes a control method for a purge assembly, which is located behind an evaporator and guides airflow through the evaporator. The method obtains the wind speed distribution on the evaporator surface when the purge plate is at a certain angle according to experimental or simulation calculations, wherein the purge plate angle is divided into multiple angles according to the purge plate movement angle range for calculation, wherein the evaporator surface wind speed distribution is divided into multiple areas according to the evaporator height for calculation, and the wind speed average value is taken for each area; according to the relationship between the purge plate movement to a certain angle and the wind speed distribution on the evaporator surface, the time when the purge plate is at a certain angle is calculated, so that the air volume passing through each area of ​​the evaporator surface in one movement cycle of the purge plate is equal.

[0038] The following technical problems have been solved:

[0039] 1. Solve the problem of no wind in local areas of the evaporator surface and improve the heat transfer efficiency of the evaporator.

[0040] 2. Solve the problem of uneven wind speed on the evaporator surface, improve the uniformity of wind speed on the evaporator surface, and improve the heat transfer effect of the evaporator.

[0041] 3. Solve the problem of low heat transfer efficiency of the evaporator, increase the overall air volume, and improve efficiency and capacity.

[0042] In some embodiments, the detection step measures the wind speed distribution on the evaporator surface when the air sweep plate is at a certain angle based on experimental or simulation calculation results, measures at a specified position on the evaporator surface using an anemometer (preferably a hot wire anemometer), and performs fluid simulation to extract the wind speed value.

[0043] The best implementation scheme of the present invention is mainly divided into three steps:

[0044] 1) Wind speed acquisition: The wind speed distribution on the evaporator surface when the sweeping plate is at a certain angle is measured based on the test or simulation calculation results. The test can use a hot wire anemometer to measure at a specified position on the evaporator surface, and the fluid simulation can directly extract the wind speed value. The wind speed distribution on the evaporator surface is divided into multiple areas according to the evaporator height for statistics, and the average wind speed is taken for each section; as shown in Table 1.

[0045] Table 1

[0046]

[0047] In some embodiments, air volume (m³ / h) = 3600 × wind speed (m / s) × surface area (m²) × time (s);

[0048] The relational expression for calculating the sum of air volumes at multiple different angles within the region in one cycle is:

[0049] Q n = 3600 × Sn × (V 10n × T 1 + V 20n × T 2 + V 30n × T 3 + V 40n × T 4 + …… + V m0n × T m )

[0050] Q n is the air volume of region n, S n is the preset area of region n, V 10n ~V m0n are the average wind speeds at region n when the angle changes from angle 1 to angle m, T 1 ~T m are the times when the wind deflector is at angles 1 to angle m respectively, where both n and m are natural numbers, and n ≥ 4, m ≥ 4.

[0051] In some embodiments, the relational expression for making the air volumes between different regions equal to each other in one cycle is:

[0052] Q 1 = Q 2 = …… Q n , that is, 3600 × S1 × (V 101 × T 1 + V 201 × T 2 + V 301 × T 3 + V 401 × T 4 + ……

[0053] + V m01 × T m ) = 3600 × S2 × (V 102 × T 1 + V 202 × T 2 + V 302 × T3 +V 402 *T 4 +……+V m02 *T m )……=3600*Sn*(V 10n *T 1 +V 20n *T 2 +V 30n *T 3 +V 40n *T 4 +……+V m0n *T m ),thus obtaining T 1 ,T 2 ……T m 。

[0054] The specific embodiments of the wind speed acquisition step of the present invention are as follows:

[0055] In the present invention, by verifying the indoor measured results of the air volume of the air conditioner and the air volume results of the fluid simulation, both are about 650 m3 / h. Therefore, the fluid simulation calculation wind speed value is adopted. According to the internal space and air flow movement of the air conditioner (preferably a cabinet air conditioner)( Figure 3 ), the length of the air deflector is equivalent to the length of the evaporator, which is 208 mm. The angular amplitude of the periodic movement of the air deflector is 90°. When the air deflector is perpendicular to the middle bracket (partition), it is 0°, and when the air deflector is parallel to the middle bracket (partition), it is 90°. According to the simulation results, when the air deflector is parallel to the middle bracket (partition), the distance from the middle bracket (partition) should be higher than the high-speed air flow to reduce the aerodynamic noise and prevent blocking the air flow. Therefore, the width of the air deflector is 40 mm.

[0056] Preferably, the fluid simulation is carried out at four movement angles of the air deflector at 0°, 30°, 60°, and 90°. Then m = 4, and T1, T2, T3, and T4 are the times when the air deflector is at angles 1 to 4 respectively, angle 1 = 0°, angle 2 = 30°, angle 3 = 60°, and angle 4 = 90°.

[0057] The fluid simulation is carried out at four movement angles of the air deflector at 0°, 30°, 60°, and 90° respectively. The wind speed on the evaporator surface at 0° is as Figure 4 shown, and the red area is the area with a larger wind speed. In the original machine state, since the distance between the outer frame of the axial flow fan blade and the upper surface of the evaporator is too close, the air volume here is small. Therefore, compared with the original machine, the air deflector solves the problem of no wind and too small wind speed in the local area at the top of the evaporator, and it can be seen the role of the air deflector in guiding the air flow.

[0058] Preferably, the wind speed distribution of multiple regions on the surface of the evaporator is statistically analyzed by dividing it into multiple regions according to the height of the evaporator, and the average wind speed is taken for each cross-section. That is, different regions on the surface of the evaporator are selected at different heights along the evaporator.

[0059] In some embodiments, the height of the evaporator of the air conditioner is L, which is vertically divided into n regions, and the average wind speed value is extracted for each region to calculate the air volume of the region, so as to control the wind speed of different regions according to different evaporator heights and different angles of the air deflector. Here, the air conditioner is preferably a cabinet air conditioner, but is not limited to cabinet air conditioners, and can also be applied to other types of air conditioners.

[0060] Preferably, the height of the evaporator of the cabinet air conditioner is 300 mm, which is divided into 10 layers, and the wind speed value is extracted for one region every 30 mm. That is, the height of the evaporator region of region 1 is 3 mm, the height of the evaporator region of region 2 is 6 mm, the height of the evaporator region of region 3 is 9 mm, the height of the evaporator region of region 4 is 12 mm, the height of the evaporator region of region 5 is 15 mm, the height of the evaporator region of region 6 is 18 mm, the height of the evaporator region of region 7 is 21 mm, the height of the evaporator region of region 8 is 24 mm, the height of the evaporator region of region 9 is 27 mm, and the height of the evaporator region of region 10 is 30 mm; thus, the wind speed of different regions is detected according to different evaporator heights and different angles of the air deflector.

[0061] Output the wind speed distribution on the surface of the evaporator according to the fluid simulation calculation results. It is known that the height of the evaporator of this cabinet air conditioner is 300 mm, which is divided into 10 layers, and the wind speed value is extracted for one region every 30 mm. The wind speed distribution results on the surface of the evaporator with air deflectors at different angles are as follows. The abscissa is the height position of the evaporator surface region, and the ordinate is the movement angle of the air deflector. It can be seen that when the air deflector is not moving, the wind speed distribution on the surface of the evaporator is relatively uneven. The simulation results are as follows in the table.

[0064] 2) Solving time: According to the air volume (m³ / h) = 3600 * wind speed (m / s) * surface area (m²) * time (s). Calculate the air volume passing through each region on the surface of the evaporator within one movement cycle of the air deflector. Taking region 1 as an example.

[0065] Q 1 = 3600 * S 1 * (V 101 * T 1 + V 201 * T 2 + V 301 * T 3 + V 401 * T4 )

[0066] Q 1 is the air volume of area 1, S 1 is the preset area of area 1, V 101 ~V 401 is the average wind speed at area 1 when the angle changes from angle 1 to angle 4, T 1 ~T 4 is the time when the swing plate distribution is at angles 1 to 4.

[0067] Calculate Q 1 ~Q 10 expressions respectively, and solve for T 1 ~T 4 Make Q 1 ~Q 10 equal. Then within one movement cycle of the swing plate (T = T 1 + T 2 + T 3 + T 4 ), the air volumes passing through each area 1 - 10 on the evaporator surface are equal.

[0068] The specific embodiments of the time calculation steps of the present invention are as follows:

[0069] Considering the air volume calculation, the air volume calculation for each area on the evaporator surface within one movement cycle is simplified and defined as:

[0070] Q i = V ij * T j

[0071] It is considered that the product of the average wind speed of each area on the evaporator surface at different angles of the swing plate and the residence time of the swing plate at different angles is the air volume of the corresponding area within one movement cycle. By controlling the time matrix, the air volumes of each area are evenly distributed, and the average wind speeds of each area within one movement cycle are evenly distributed.

[0072] Therefore, substitute the wind speed distribution matrix and solve the system of linear equations:

[0073] v = [1.39 2.35 1.62 1.29; 3.58 2.08 1.87 1.19; 1.35 2.44 1.92 1.34; 0.67 1.34 1.72 1.13; 0.75 1.21 1.53 1.40; 0.84 1.04 1.67 2.02; 0.87 0.94 1.56 2.16; 0.84, 1.04, 1.51, 2.05; 0.78, 0.94, 1.47, 1.98; 0.67, 0.96, 1.31, 1.88];

[0083] Q = ones(10,1);

[0084] T = Q\V.

[0085] The time matrix is obtained by solving. The residence times of the air deflector at each angle (0°, 30°, 60°, 90°) are successively (one motion cycle is 1): [0.2000, 0.2443, 0.2756, 0.2801]

[0086] By controlling the movement of the air deflector, the problem of uneven air velocity on the evaporator surface is solved, the air velocity distribution on the evaporator surface is improved, and the heat transfer effect of the evaporator is enhanced.

[0087] 3) Motion fitting: According to the air deflector angles 1 to angle 4 and time T 1 ~T 4 The motion speed of the air deflector is fitted with a quadratic polynomial. A continuous curve is fitted through 4 different angles and 4 different times (discrete points) to obtain the angular velocity (angle / time).

[0088] Implementation effect: By controlling the angle of the air deflector, the air volume passing through each area on the evaporator surface within one motion cycle of the air deflector is made equal, the air volume passing through the evaporator surface is evenly distributed, the heat transfer efficiency of the evaporator is improved, and the heat transfer effect of the evaporator is enhanced.

[0089] In some embodiments, the calculation of the air volume in each area on the evaporator surface within one motion cycle is simplified and defined as:

[0090] Q i = V ij *T j

[0091] where i is the area number, j is the angle number, and there is V 1 = V 2 =... V i =... V n , 1 ≤ i ≤ n, 1 ≤ j ≤ m.

[0092] In some embodiments, the angle F(T) is fitted with time T to obtain: F(T) = p1*T^3 + p2*T^2 + p3*T + p4, where p1, p2, p3, and p4 are all coefficients, and there are: p1 = 1.00 to 1.05, p2 = -2.40 to -2.31, p3 = 5.10 to 5.80, p4 = -0.09 to -1.10;

[0093] Then the angular velocity of the swing plate movement is F 1 (T) = 3p1*T^2 + 2p2*T + p3, preferably p1 = 1.00 to 1.05, p2 = -2.40 to -2.31, p3 = 5.10 to 5.80.

[0094] In some embodiments, the variable-speed movement of the swing plate is controlled by separately controlling the different values of p1, p2, and p3. Further preferably, p1 = 1.033, p2 = -2.346, p3 = 5.461, p4 = -1.007.

[0095] The specific implementation manner of the movement fitting step of the present invention is as follows:

[0096] It is considered that the movement angle of the swing plate is related to the surface wind speed and air volume distribution of the evaporator. According to the calculation results of the swing plate movement angle and time, the swing plate movement angle is fitted, and a cubic polynomial is adopted. The fitting results are as follows: and as Figure 5 shown.

[0097] F(T) = p1*T^3 + p2*T^2 + p3*T + p4

[0098] where preferably p1 = 1.00 to 1.05, p2 = -2.40 to -2.31, p3 = 5.10 to 5.80, p4 = -0.09 to -1.10;

[0099] Further preferably, p1 = 1.033, p2 = -2.346, p3 = 5.461, p4 = -1.007

[0100] The movement speed of the swing plate is the first derivative of the swing plate angle, and the calculation results are as follows:

[0101] F 1 (T) = 3p1*T^2 + 2p2*T + p3,

[0102] Preferably, F 1 (T) = 3.099*T^2 - 4.692*T + 5.461

[0103] T is time, F 1 is the angular velocity, and F is the angle.

[0104] In summary, a method for controlling the movement of the air-sweeping plate is obtained. By controlling the movement speed of the air-sweeping plate, the wind speed passing through the surface of the evaporator is made uniform within a movement cycle, the heat transfer efficiency of the evaporator is improved, and the heat transfer effect of the evaporator is enhanced.

Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention. The above is only the preferred implementation manner of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and modifications can still be made, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
