Description

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 deflecting blades and an indoor fan capable of controlling the direction and flow rate of a blown air flow 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 example of Japanese Patent Laid-Open No. 6-94219 is known as a technique for making a user feel a change in air flow that is close to natural and improving comfort. The configuration will be described below.

The storage unit of the control unit for controlling the fan motor rotation speed of the indoor unit stores data such that the wind speed of the air flow produced by the air conditioner causes chaotic fluctuations, and the motor rotation speed is calculated based on the data. Change with time.
That is, in order to reproduce the airflow with fluctuations that cause chaotic fluctuations in the room, the rotation speed of the blower drive motor is controlled so that the airflow in the living space undergoes chaotic fluctuations, and the blower is operated based on that, The amount of discharge, that is, the amount of blown airflow, is changed so that the user feels a change in airflow that is close to natural, thereby improving comfort. Further, in the embodiment disclosed in JP-A-6-74544, the fan motor rotation speed of the indoor unit or the swaying angle of the wind direction plate arranged at the air outlet, that is, the angle of the deflection blade is controlled regardless of the outlet temperature, and it is close to natural. The change in air flow is felt by the user to improve comfort.

[0004]

However, in the above configuration, for example, if the wind direction is always directed to the user by simply controlling the fan motor rotation speed and changing the air flow, the change in the air flow is not enough. Like the natural airflow, the user cannot feel the change when the airflow hits and when it does not. In addition, even if the compressor rotation speed in the outdoor unit is constant, the blowing temperature decreases when the air volume decreases during cooling operation, and conversely, the blowing temperature increases when the air volume increases. There is a case where the user feels a cold blast due to a temperature change, particularly a decrease in the blowing temperature, and gives a discomfort to the user.

Further, simply changing the wind direction to change the chaos makes the user feel cold blast at a low blowing temperature when the wind direction is high, such as when the load is large and the compressor rotation speed is high, which is very uncomfortable. There was a problem that there is.

In view of the above problems, the present invention makes it possible to chaotically change the wind speed at a predetermined position in the room without causing the user to feel a cold wind during the cooling operation.
The purpose of this is to make the user feel a change in airflow that is close to nature and to improve comfort.

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic block diagram of a control device for an air conditioner according to an embodiment of the present invention. In FIG. 1, 1 is a blowout temperature detecting means, 11 is a room temperature stability determining means, 2 is a deflection speed chaos data generating means, 3 is a deflection speed determining means, and 4 is an air conditioner. Here, the blowout temperature detecting means 1 is not limited as long as it detects the blowout temperature, such as estimating the blowout temperature from the pipe temperature. Further, the room temperature stability determination means 11 estimates the room temperature stable / transient state from the rate of change in room temperature,
The means is not limited as long as it detects a stable state at room temperature.

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

The room temperature stability judging means 11 judges the stable state of the room temperature, for example, from 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 deflection velocity chaos data generating means 2,
Data for making the user feel a change in the airflow that is close to nature, for example, data calculated by the Lorentz equation that simplifies the weather variation model, is output to the deflection velocity determination means 3 as a deflection velocity chaos data signal.

The wind speed can be chaotically changed at the position, and the user can feel a change in the air flow that is more natural.

Next, the Lorentz equation will be used as an example to describe the details of the deflection velocity chaos data generating means 2. The Lorentz equation is represented by the following differential equation.

Dx / dt = 10y-10x (1.1) dy / dt = -xz + 28x-y (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 range. Further, t represents continuous time.

-24 ≤ x <24 -32 ≤ y <320 0 ≤ z <64 Here, x is a deflection velocity chaotic data which is treated as a deflection velocity.
The data signals, y and z are values for calculating x.
Equation (1.1) becomes dx = (10y-10x) dt (1.4), and x_{n + 1}= X_n+ Dx_n Since it is (1.5), from equations (1.4) and (1.5), x_{n + 1}= X_n+ (10y_n-10x_n) Dt (1.6). y_{n + 1}, Z_{n + 1}Is the same as y_{n + 1}= Y_n+ (28x_n+ Y_n-X_nz_n) Dt (1.7) z_{n + 1}= Z_n+ ((-8/8) x_n+ X_ny_n) Dt becomes (1.8), and the equations (1.6), (1.7) and (1.8) become
Initial value (x₀, Y₀, Z ₀) And dt
The values of x, y, and z are calculated one after another.

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

FIG. 3 shows an example of a region in which a user feels uncomfortable due to a feeling of cool air when the air-conditioning apparatus is in a cooling operation and the blowing temperature and the deflection speed are changed to move the deflecting blades up and down by a specified angle. As can be seen from FIG. 3, during the cooling operation of the air conditioner, the user feels uncomfortable due to the feeling of cold wind when the deflection speed is slowed when the blowout temperature is lowered to some extent.

Table 1 shows the deflection velocity regions classified according to the blowing temperature and the stability determination result, Table 2 shows the deflection velocity for each deflection velocity region corresponding to the deflection velocity chaos data, and x is the deflection velocity. This is a chaotic data signal for deflection speed output from the chaotic data generating means 2 for. In Table 1,
The optimum deflection speed region, ... Is determined in accordance with the blowing temperature and the stability determination result. In Table 2, the deflection speed increases in the order of area ,. 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 very low in the region, the user does not feel a cold wind for a long time, and The deflection speed is determined fast regardless of the deflection speed chaos data. In the region, the blowing temperature is such that the user does not feel uncomfortable even if the airflow is applied to the user. The wind speed is chaotically changed at a predetermined position in the room without making the user feel, and the deflection speed that allows the user to feel a change in the airflow that is close to natural is determined. Similarly, between the region and the region, the optimum deflection speed for the user is determined according to the blowing temperature.
Further, when the room temperature is in a transient state, for example, when the room is not yet cooled, it is more comfortable for the user to apply an airflow, and therefore the region is switched so that the deflection speed becomes slower.

Based on the velocity chaotic data signal, the deflection velocity for chaotically varying the wind velocity at a predetermined position in the room is determined without making the user feel a cold wind, and as a deflection velocity determination signal,
Output to the air conditioner 4.

Next, details of the air conditioner 4 will be described. In the air conditioner 4, the deflection speed determination signal, which is the output value from the deflection speed determination means 3, is set as the speed for moving the deflection blade until the deflection blade reciprocates up and down one designated angle. For example, the above 6, 6, 4, 6, 10 ° / sec ... Further, if the deflecting blade is moved vertically from 0 ° to 45 ° downward, the first deflecting blade moves at a deflecting speed of 6 ° / sec.
The blade is lowered from 0 ° to 45 ° and the same deflection speed is 6 °
The blade is controlled to be lifted from 45 ° to 0 ° per second. If this is expressed as a symbol "6 ° / sec: 0 ° → 45 ° → 0 °", from the second time, "" 6 ° / sec: 0 ° → 45 ° →
0 ° ”,“ 4 ° / sec: 0 ° → 45 ° → 0 ° ”,“ 6 ° /
Second: 0 ° → 45 ° → 0 ° ”,“ 10 ° / sec: 0 ° → 45
The control is as follows: ° → 0 ° ”.

As a result, when the change in the wind speed near the user is modeled, the result is as shown in FIG. 4, and the user can feel a change in the air flow that is close to natural. Therefore, comfort can be improved.

As described above, according to the first embodiment, the deflection speed of the deflection blade is determined based on the blowing temperature, the stability determination result, and the deflection speed chaos data, so that the user feels cool air. It is possible to cause the wind speed to change chaotically at a predetermined position in the room without making the user feel, and to make the user feel a change in the airflow that is close to nature. Therefore, comfort can be improved.

Next, a second embodiment of the present invention will be described with reference to the drawings with reference to FIG. Here, the same components as those in the first embodiment are denoted by the same reference numerals and the description thereof will be omitted. In FIG. 5, 5 is a retention time chaos data generation means, and 6 is a retention time determination means. The operation of the above configuration will be described below.

That is, in consideration of the relationship between the blowing temperature and the holding time as shown in FIG. 6, according to Tables 4 and 5, when the blowing temperature is very low in the region, the user does not feel a cold wind for a long time, Retention time Regardless of the chaotic data, the retention time is determined to be short.Because the temperature is the blowing temperature that does not make the user feel uncomfortable when the airflow is applied to the region, the user feels a cold sensation according to the retention time chaotic data. Instead, the wind speed is chaotically fluctuated at a predetermined position in the room, and the holding time that allows the user to feel a change in the airflow that is close to nature is determined.
Similarly, between the region and the region, the optimum holding time for the user is determined according to the blowing temperature. Further, when the room temperature is in a transient state, for example, when the room is not yet cooled, it is more comfortable for the user to apply an airflow, and therefore the regions are switched so that the holding time becomes longer.

As described above, in the blade angle determining means 8, the blowing temperature signal, the stability determination result signal, and the angle, which are output values from the blowing temperature detecting means 1, the room temperature stability determining means 11 and the angular chaos data generating means 7. Based on the chaos data signal, the blade angle for chaotically varying the wind speed is determined at a predetermined position in the room without making the user feel a cold wind, 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 set as the descent angle from the horizontal 0 ° reference angle of the deflection blade when the deflection blade is moved in the vertical direction by a specified angle, for example, Above 12, 12, 3, 12, 28
.., the first movement of the deflecting blade is controlled so as to lower the blade from 0 ° to 12 ° and raise the blade from 12 ° to 0 °. This is a symbol "0 ° → 12 °

As a result, when a change in the wind speed near the user is modeled, the result is as shown in FIG. Therefore, comfort can be improved. Note that the horizontal angle of 0 ° is used as the reference angle here, but the value is not limited.

As described above, according to the third embodiment, the angle of the deflecting blades is determined based on the blowing temperature, the stability determination result, and the angle chaos data, so that the user feels a cold sensation. Instead, the wind speed can be chaotically changed at a predetermined position in the room, and the user can feel a change in air flow that is close to nature. Therefore, comfort can be improved.

In FIG. 11, 9 is an air volume chaos data generating means, and 10 is an air volume determining means. The operation of the above configuration will be described below.

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

In the air conditioner 4, by controlling the air volume based on the air volume determination signal, which is the output value from the air volume determination means 10, the wind velocity can be obtained at a predetermined position in the room without making the user feel cold. It is possible to cause the user to feel a change in air flow that is close to nature by changing chaos.

Next, details of the air volume determining means 10 will be described with reference to FIG. 12 and tables 10 and 11. FIG. 12 is an example showing an area in which the user feels uncomfortable due to the feeling of cold air when the blowing temperature and the air volume are changed 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 uncomfortable due to the feeling of cold air when the air flow rate is low and the air volume is increased.

Table 10 shows the air volume classified according to the blowing temperature and the stability determination result, Table 11 shows the air volume for each air volume region corresponding to the air volume chaos data, and xq is the air volume chaos data generating means 10. This is the chaotic data signal for the air volume output from. In Table 10, the optimum air volume region corresponding to the blowing temperature and the stability determination result,
Has been decided. For Table 11, the areas ...
The maximum value of air volume increases in the order of. That is, in consideration of the relationship between the blowing temperature and the air volume as shown in FIG. 12, according to Tables 10 and 11, the air volume is reduced so that the user does not feel the cold air when the blowing temperature is very low in the region. In the region, the blowing temperature is such that the user does not feel uncomfortable even if the airflow is applied to the user, so the airflow is determined so that the airflow fluctuates in accordance with the airflow chaos data. Similarly, between the region and the region, the optimum air volume for the user is determined according to the blowing temperature. Also, if the room temperature is transient,
For example, when the room is not cold yet, it is more comfortable for the user to apply an airflow, so the area is switched so that the air volume is increased.
