DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device for an air conditioner having a deflecting blade and an indoor fan capable of controlling the direction and air volume of an airflow blown from an indoor unit.

[0002]

2. Description of the Related Art A conventional control device for an air conditioner of this type will be described. In recent years, for example, a configuration described in an embodiment of Japanese Patent Application Laid-Open No. 6-94219 is known as a technique for causing a user to feel a change in airflow that is almost natural and improving comfort. The configuration will be described below.

[0003] In a storage unit of a control device for controlling the number of revolutions of a fan motor of an indoor unit, data is stored so that the wind speed of an airflow produced by the air conditioner fluctuates in chaos, and the number of revolutions of the motor is determined based on the data. Vary over time.
In other words, in order to reproduce the airflow with fluctuations that cause chaos fluctuations in the room, by controlling the rotation speed of the blower drive motor so that the airflow in the living space fluctuates chaos, and by operating the blower based on it, The discharge amount, that is, the airflow amount of the blown airflow is changed to make the user feel a change in the airflow which is almost natural, thereby improving comfort. Further, in the embodiment of JP-A-6-74544, the rotation speed of the fan motor of the indoor unit or the swing angle of the wind direction plate provided at the air outlet, that is, the angle of the deflecting blade, is controlled irrespective of the blowout temperature, and it is almost natural. It is intended to make the user feel the change in airflow and to improve comfort.

[0004]

However, in the above-described configuration, for example, if the airflow direction is always directed to the user by simply controlling the fan motor speed and changing the airflow, the change in the airflow alone is not sufficient. As in the case of natural airflow, the user cannot feel the change between when the airflow hits and when it does not hit. In addition, even when the compressor rotation speed in the outdoor unit is constant, the blowing temperature decreases when the air volume decreases during the cooling operation, and the blowing temperature increases when the air volume increases. The user may feel a strong sense of cold wind due to a temperature change, particularly a drop in the blowing temperature, which may give the user discomfort.

Further, simply changing the wind direction and changing the chaos simply causes the user to feel a cool air feeling at a low blowing temperature when the wind direction is turned, such as when the load is large and the compressor rotation speed is high, which is very unpleasant. There was a problem that there is.

[0006] In view of the above problems, the present invention provides a method of causing a user to change the wind speed at a predetermined position in a room without causing the user to feel a cold wind during cooling operation.
The purpose is to make the user feel a change in airflow close to nature and to improve comfort.

In FIG. 1, reference numeral 1 denotes an outlet temperature detecting unit, 11 denotes a room temperature stability determining unit, 2 denotes a deflection speed chaos data generating unit, 3 denotes a deflection speed determining unit, and 4 denotes an air conditioner. Here, the outlet temperature detecting means 1 is not limited as long as it detects the outlet temperature, such as estimating the outlet temperature from the pipe temperature. Further, the room temperature stability determination means 11 estimates a stable / transient state of the room temperature from the rate of change of the room temperature, and the like.
The means for detecting a stable state at room temperature is not limited.

The operation of the above configuration will be described below. The blowout temperature detecting means 1 detects the temperature of the airflow blown from the indoor unit of the air conditioner 4 by a blowout temperature sensor such as a thermistor, and outputs the detected temperature to the deflection speed determining means 3 as a blowout temperature signal.

The room temperature stability judging means 11 judges the stable state of the room temperature from, for example, the temperature of the air sucked into the indoor unit of the air conditioner 4, and outputs it to the deflection speed determining means 3 as a stability judgment result signal.

In the chaotic data generating means 2 for deflection speed,
Data for causing the user to feel an airflow change close to nature, for example, data calculated by a Lorentz equation that simplifies a weather variation model, is output to the deflection speed determining means 3 as a deflection speed chaos data signal.

It should be noted that if the data is such that the user feels a change in the air flow that is almost natural, such as using a wrestler equation other than the Lorentz equation, or using the natural air flow fluctuation pattern as chaotic data for the deflection speed directly, Is not limited.

Based on the signal, without giving the user a feeling of cold wind,

It is possible to cause the wind speed to fluctuate by chaos at the position, and to make the user feel a more natural change in airflow.

Next, using the Lorentz equation as an example, the details of the deflection speed chaos data generating means 2 will be described. The Lorentz equation is represented by the following differential equation.

Dx / dt = 10y−10x (1.1) dy / dt = −xz + 28xy (1.2) dz / dt = xy− (8/3) z (1.3) In the above equation, x, y and z are state variables and fall within the following ranges. Also, t represents a continuous time.

The expression (1.1) becomes dx = (10y−10x) dt (1.4), and x_{n + 1}= X_n+ Dx_n (1.5) Since (1.4) and (1.5), x_{n + 1}= X_n+ (10y_n-10x_n) Dt (1.6). y_{n + 1}, Z_{n + 1}Similarly, y_{n + 1}= Y_n+ (28x_n+ Y_n-X_nz_n) Dt (1.7) z_{n + 1}= Z_n+ ((− 8/3) x_n+ X_ny_n) Dt (1.8), and the expressions (1.6), (1.7) and (1.8)
Initial value (x₀, Y₀, Z ₀) And dt
The values of x, y, z are calculated one after another.

As an example, FIG. 2 shows (x ₀ , y ₀ , z ₀ ) =
X, y, z when (1, 1, 1), dt = 0.02
Represents the change. In FIG. 2, the vertical axis represents values of x, y, and z, and the horizontal axis represents n. If Δn = 8, the value of x is x ₀ = 1 × ₈ = 3.49 × ₁₆ = 16.55 × ₂₄ = 2.31 × ₃₂ = −12.04.

FIG. 3 shows an example of an area in which the user feels discomfort due to a feeling of cool wind when the air conditioner is operated at a specified angle in the vertical direction by changing the blowing temperature and the deflection speed during the cooling operation of the air conditioner. As can be seen from FIG. 3, during the cooling operation of the air conditioner, if the blowing temperature is reduced to some extent, the user feels discomfort due to the feeling of cool wind when the deflection speed is reduced.

Table 2 shows the deflection speeds in each deflection speed range corresponding to the deflection speed chaos data. 3 is a chaotic data signal for deflection speed output from the chaotic data generating means 2. In Table 1,
The optimum deflection speed region is determined according to the blowing temperature and the stability determination result. In Table 2, the deflection speed increases in the order of region,. That is, in consideration of the relationship between the blowing temperature and the deflection speed as shown in FIG. 3, according to Tables 1 and 2, when the blowing temperature is extremely low in the region, the airflow hits the user for a long time so that the user does not feel a cool wind. Deflection speed is determined fast regardless of the deflection speed chaos data.In the region, the blowing temperature is not uncomfortable even if the user is exposed to airflow. The wind speed is chaotically fluctuated at a predetermined position in a room without causing the user to feel the airflow, and the deflection speed at which the user can feel a change in airflow that is almost natural is determined. Similarly, the deflection speed optimum for the user is determined between the region and the region in accordance with the blowing temperature.
In addition, when the state of the room temperature is transient, for example, when the room is not yet cooled, it is felt that it is more comfortable to apply a slight airflow to the user, so that the area is switched so that the deflection speed is reduced.

Therefore, comfort can be improved.

Next, a second embodiment of the present invention will be described with reference to FIG. Here, the same components as those in the first embodiment are denoted by the same reference numerals, and the description is omitted. In FIG. 5, reference numeral 5 denotes a holding time chaos data generating unit, and 6 denotes a holding time determining unit. The operation of the above configuration will be described below.

Regardless of the holding time chaos data, the holding time is determined to be short, and in the area, the blowing temperature does not become uncomfortable even if the user is exposed to airflow, so the user feels a cool air feeling according to the holding time chaos data. Without changing the airflow, the wind speed is chaotically varied at a predetermined position in the room, and the holding time in which the user can feel a change in the airflow close to nature is determined.
Similarly, the optimal holding time for the user is determined between the region and the region in accordance with the blowing temperature. In addition, when the state of the room temperature is transient, for example, when the room is not yet cooled, it is more comfortable to apply a slight airflow to the user, so the area is switched so that the holding time becomes longer.

Based on the chaos data signal, the blade angle at which the wind speed is chaotically varied at a predetermined position in the room without causing the user to feel a cool wind is determined, and is output to the air conditioner 4 as a blade angle determination signal.

Next, details of the air conditioner 4 will be described. In the air conditioner 4, the blade angle determination signal, which is the output value from the blade angle determination means 8, is used as the descending angle from the horizontal 0 ° reference angle of the deflecting blade when the deflecting blade is moved up and down by a specified angle. The above 12, 12, 3, 12, 28
.., The first movement of the deflecting blade is controlled to lower the blade from 0 ° to 12 ° and raise the blade from 12 ° to 0 °. This is symbolized as “0 ° → 12 °
→ 0 ° ”, from the second time,“ 0 ° → 12 ° → 0
° ”,“ 0 ° → 3 ° → 0 ° ”,“ 0 ° → 12 ° → 0 ”
° ”,“ 0 ° → 28 ° → 0 ° ”.

As a result, when the change in the wind speed near the user is modeled, the result is as shown in FIG. 10, and the user can feel a change in the air flow which is almost natural. Therefore, comfort can be improved. Although the horizontal angle of 0 ° is used as the reference angle here, the value is not limited.

As described above, according to the third embodiment, the user can feel the feeling of cool air by determining the angle of the deflecting blade based on the blowing temperature, the stability determination result, and the chaos data for angle. Without causing this, the wind speed is chaotically fluctuated at a predetermined position in the room, so that the user can feel an airflow change that is almost natural. Therefore, comfort can be improved.

Next, a fourth embodiment of the present invention will be described with reference to FIG. Here, the first and second
The same components as those of the third and third embodiments are denoted by the same reference numerals, and description thereof is omitted. In FIG. 11, reference numeral 9 denotes an air volume chaos data generating unit, and 10 denotes an air volume determining unit. The operation of the above configuration will be described below.

The air flow chaos data generating means 9 calculates the initial values (xq ₀ , yq ₀ , zq ₀ ) =

The air volume determining means 10 is based on the air temperature signal, the stability determination result signal and the air volume chaos data signal which are output values from the air temperature detecting means 1, the room temperature stability determining means 11 and the air volume chaotic data generating means 9. The chaotic fluctuation of the wind speed at a predetermined position in the room,
An airflow that allows the user to feel a change in airflow close to nature is determined, and is output to the air conditioner 4 as an airflow determination signal.

The air conditioner 4 controls the air flow based on the air flow determination signal, which is the output value from the air flow determining means 10, so that the user does not feel the feeling of cool air, and the wind speed at a predetermined position in the room is controlled. Can be varied by chaos so that the user can feel a change in airflow close to nature.

Next, details of the air volume determining means 10 will be described with reference to FIG. 12, Tables 10 and 11. FIG. 12 shows an example of a region in which the user feels uncomfortable due to a feeling of cool air when changing the blowout temperature and the air volume during the cooling operation of the air conditioner. As can be seen from FIG. 12, during the cooling operation of the air conditioner, the user feels discomfort due to a feeling of cool wind when the air volume is increased when the blowing temperature is low.

Table 10 shows the air volume classified for each of the blowing temperature and the stability determination result. Table 11 shows the air volume for each air volume area corresponding to the air volume chaos data, and xq indicates the air volume chaos data generation means 10. Is a chaotic data signal for air volume output from. In Table 10, the optimal air volume region corresponding to the blowing temperature and the stability determination result,
Is determined. For Table 11, the areas,.
The maximum value of the air volume increases in the order of. That is, in consideration of the relationship between the blow-off temperature and the air flow as shown in FIG. 12, according to Tables 10 and 11, the air flow is reduced so that the air flow hits the user when the blow-out temperature is extremely low in the region so that the user does not feel a cool wind. In the region, since the blowout temperature is such that the airflow does not become uncomfortable even when the airflow is applied to the user, the airflow is determined so that the airflow fluctuates according to the airflow chaos data. Similarly, the optimum air volume for the user is determined between the area and the area in accordance with the blowing temperature. If the room temperature is transient,
For example, when the room is not yet cooled, it is felt that it is more comfortable to apply some airflow to the user, so the area is switched so as to increase the air volume.
