Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner for performing comfort control by changing the blowing speed of air that is air-conditioned by an indoor unit and blown into a room in the same manner as a natural phenomenon.

[0002]

2. Description of the Related Art As a conventional air conditioner as described above, for example, as shown in Japanese Patent Laid-Open No. 2-203147, a fluctuation frequency f related to a change in the blowing wind speed of air blown from an indoor unit during a cooling operation is set. The possible region is divided into a plurality of frequency bands in advance, and the fluctuation frequency f
Is set for each of the divided frequency bands, and the relationship between the fluctuation frequency f and the amount of change in the power spectrum is set to "1.
/ F-law "is set for each of the above-mentioned divided frequency bands, and the blow-off wind speed is controlled to fluctuate using the relationship of" 1 / f-law "for each frequency band. There is one that attempts to improve comfort control by performing a cooling operation so that Further, for example, as disclosed in Japanese Patent Laid-Open No. 3-134429, when performing a timer operation at bedtime, the rotational speed of the compressor is decreased stepwise, and the blowing speed of air into the room is set to "1. / F
There is an air conditioner that attempts to achieve comfortable control by gradually reducing the fluctuation air flow according to the "rule". The air conditioners disclosed in these documents all consider "1 / f fluctuation" as a fluctuation pattern of the wind speed change in a natural phenomenon, and control the blowing wind speed in accordance with the "1 / f fluctuation" pattern, for example, a breeze. It is intended to realize comfortable air-conditioning operation close to a natural phenomenon such as.

[0003]

By the way, the strength and direction of the wind in the natural world are not constant and constantly changing, and there are several kinds of wind power depending on the relationship between the fluctuation frequency and the power spectrum concerning the amount of change in strength. It is classified as a "fluctuation" phenomenon. For example, (a) in FIG.
The relationship of "1 / f ⁰ fluctuation" shown in is the case where the power spectrum is constant but the width of the change period is wide.
The relationship of “1 / f ∞ fluctuation” shown in (b) is a case where the fluctuation cycle remains long and does not change. In addition, the relationship of "1 / f ² fluctuation" shown in (c) is a relationship in which the fluctuation period changes a little with respect to the fluctuation of the power spectrum. Furthermore, the relationship of "1 / f fluctuation" shown in (d) is as follows: "1 / f ⁰ fluctuation" and "1 / f fluctuation"
^This is a relationship that represents an intermediate stimulus of each relationship of " ² fluctuations", and is a relationship in which the power spectrum changes in accordance with changes in the change cycle. In other words, the power spectrum of a phenomenon that changes slowly is large, and the power spectrum of a phenomenon that changes rapidly is small. Generally, it is said that a person feels comfortable with the "1 / f fluctuation" stimulus given from the outside. More specifically, it is well known that a person feels comfortable with a stimulus of the same quality as the current emotional state of the person. For example, for a person in an emotional state who is trying to relax in a completely awake state, the stimulus of "1 / f fluctuation" is felt comfortable, but
The stimuli of "1 / f ⁰ fluctuation" and "1 / f ² fluctuation" are not felt comfortable. Also, for a person in an emotional state who is trying to be active, the stimulus of "1 / f fluctuation" feels boring, and rather, the stimulus of "1 / f ⁰ fluctuation" feels more comfortable. Furthermore, for a person in an emotional state who is about to sleep, the stimulation of "1 / f ² fluctuation" to "1 / f ∞ fluctuation" does not interfere with the sleep and feels more comfortable. However, according to the conventional device, since the air blow control in which the blowout wind speed changes in "1 / f fluctuation" or in a single cycle is only performed,
As described above, for example, “1 / f ⁰ fluctuation” or “1 / f ²
It is hard to say that it is a device that gives a feeling of comfort to a person in an emotional state who desires the stimulus of “fluctuation”. Further, in the air conditioner disclosed in Japanese Patent Laid-Open No. 2-203147, "1
Since the relationship of "/ f fluctuation" is adopted, the fluctuation fluctuation output, that is, the power spectrum is large in the low frequency frequency band, and the power spectrum becomes small as the frequency band becomes high. However, when performing the air-conditioning operation at bedtime, it is preferable that the change frequency of the blowing air speed is not frequent and the blowing air speed is small. On the contrary, in the air conditioning operation for getting up,
It is preferable that the change cycle of the blowing air speed be frequent to increase the stimulation caused by this change and to increase the blowing air speed. However, the conventional air conditioner described above cannot realize the air conditioning operation in which the fluctuation cycle is changed according to the state of the person. Then, the 1st objective of this invention is to provide the air conditioner which can give a feeling of comfort to the person in the emotional state according to a person's emotional state. A second object of the present invention is to provide an air conditioner capable of giving a comfortable feeling to a person who is in an emotional state when getting up and a person who is in an emotional state when sleeping.

[0004]

In order to achieve the first object, the main means adopted by the first invention is, in the gist thereof, air-conditioned by an indoor unit and blown out into the room. An area to be controlled which is related to a change in the output amount of the controlled object is divided into a plurality of frequency bands in advance, and the controlled frequency is related to the fluctuation frequency f and the output of the controlled object. Set the relationship with the amount of change in force for each of the frequency bands divided above,
In the air conditioner in which the relationship between the frequency bands is switched and the output amount of the controlled object is controlled by the fluctuation frequency f corresponding to the output amount from the switched relationship, the relationship between the frequency bands is changed to a low frequency. Fluctuation frequency f defined using a coefficient k that increases in value in the frequency band of
The air conditioner is characterized by being set according to the 1 / f ^k rule. Further, in order to achieve the above-mentioned second object, the main means adopted by the second invention is the gist of the main means, which is related to the blowing speed of the air blown into the room after air conditioning is performed by the indoor unit. A relationship between the fluctuation frequency f and the amount of change in the output amount of the controlled object is divided into a plurality of frequency bands in advance by including a controlled object, and a region in which the fluctuation frequency f related to the change of the output amount of the controlled object can be obtained. Is set for each of the divided frequency bands, the relationship between the frequency bands is switched, and the output amount of the controlled object is controlled by the fluctuation frequency f corresponding to the output amount from the switched relationship. In the above, the air conditioner is characterized in that the relationship between the respective frequency bands is set such that the level of the amount of change in the output amount of the controlled object becomes smaller as the frequency band becomes lower. It is configured as a Japanese machine. Further, in order to achieve the above first and second objects, the main means adopted by the third invention is, in summary, the air conditioning performed by the indoor unit and the air blown out into the room. An area to be controlled which is related to a change in the output amount of the controlled object is divided into a plurality of frequency bands in advance, and the fluctuation frequency f and the output amount of the controlled object are controlled. Set the relationship with the amount of change for each of the divided frequency bands, switch the relationship between each frequency band,
In the air conditioner that controls the output amount of the controlled object at the fluctuation frequency f corresponding to the output amount from the switched relation, the value of the relation of each frequency band becomes larger as the frequency band becomes lower. The air conditioner is set so that it has a relationship according to the 1 / f ^k rule of the fluctuation frequency f defined by using the coefficient k that is set, and that the level of the amount of change in the output amount of the controlled object is small. Configured as a machine.

The relationship between the frequency bands in the configuration according to the third aspect of the invention is such that the value of the coefficient k is minimized and the output of the controlled object is at a preset wake-up time during the operation during wake-up. It is also possible to adopt a configuration in which switching is performed so as to maximize the ability. The relationship between the frequency bands in the configuration according to the third aspect of the invention is that the coefficient k is from the start of operation at bedtime.
It is also possible to adopt a configuration in which the value of A is switched from a relationship of a small value to a relationship of a large value, and the output amount of the controlled object is switched to a relationship of a small value from a large relationship.
Furthermore, the rotation speed of the indoor blower provided in the indoor unit or the wind direction plate provided at the air outlet of the indoor unit as the output amount of the controlled object related to the blowing wind speed in the first invention to the third invention. It is also possible to use the swing angle of.

[0006]

In the air conditioner pertaining to the first aspect of the invention,
The relationship between the fluctuation frequency f and the amount of change due to fluctuations in the output of the controlled object in each frequency band in which the controlled object related to the blowing wind speed is divided with respect to the fluctuation frequency f related to the change in output is a constant relationship. Rather, it is set according to the 1 / f ^k rule of the fluctuation frequency f, which is defined by using the coefficient k whose value increases toward the lower frequency band, so that the fluctuation frequency is, for example, in the low frequency band. It is possible to control the operating state in which the output amount fluctuates greatly even if it changes slightly. On the contrary, in the high frequency band, the power spectrum hardly changes according to the 1 / f ^k rule defined by using the coefficient k having a small value, for example, even if the change cycle of the output amount largely changes. Therefore, while maintaining the relationship between the fluctuation frequency and the output change amount set as described above, by appropriately setting the level of the output change amount for each frequency band, the change cycle of the blowing wind speed and its change amount A comfortable stimulus due to the change in the blowing air speed can be given in association with the level according to the emotional state of the person. Further, in the air conditioner according to the second aspect of the present invention, since the level of the output fluctuation amount of the controlled object is small in the control state in the low frequency band, for example, a gentle control suitable for driving at bedtime. It can be performed. On the contrary, if the relationship of the frequency band of high frequency is used for the air conditioning control, a large control of the stimulus with a large fluctuation of the blowing air velocity of the air and a short fluctuation cycle of the blowing wind velocity is performed, so that the air conditioning operation during wake-up is performed. It can be said that the control is suitable. Further, in the air conditioner pertaining to the third aspect of the invention, the configuration of the first aspect of the invention and the second aspect of the invention are provided.
Since the configuration of the invention of 1) is used together, the lower the frequency band of the low frequency, the smaller the stimulus given to the person due to the change in the blowing wind speed, while the higher the frequency band of the high frequency, the more the stimulus given to the person. Can be large.

An indoor heat exchanger 5 is provided on the indoor unit B side, and these devices are connected in sequence through a refrigerant pipe 18 to form a refrigeration cycle. An outdoor blower 6 is provided near the outdoor heat exchanger 3, and an indoor blower 7 is provided near the indoor heat exchanger 5 to exchange heat between the refrigerant and the outdoor air or the indoor air. It has become. Then, the indoor control device 13 and the outdoor control device 1

The indoor control device 13 controls the rotation speed of the indoor blower 7 based on the switch input from the remote controller 14 and the input signals from the heat exchange temperature sensor 16 and the indoor temperature sensor 12, and controls the indoor unit B. Control of the elevation angle (an example of a swing angle) of a louver 10 (an example of a wind direction plate) arranged at the outlet of the casing, and the compressor 1
It has a function of controlling the operating frequency of the air conditioner and controlling the entire air conditioner 20. A motor 9 that drives the indoor blower 7 is connected to an inverter (variable frequency device) 8 that controls the rotation speed of the motor 9, and the output frequency of the inverter 8 is controlled by the indoor control device 13.
Further, the indoor control device 13 rotationally drives and controls the motor 11 for driving the louver 10, whereby the elevation angle of the louver 10 is controlled. On the other hand, the outdoor control device 15
Identifies the operation command content based on the serial signal transmitted from the indoor control device 13, and based on the operation command content and the output signals from the current sensor (not shown) and the outdoor heat exchange temperature sensor (not shown). In addition, the output frequency of the inverter (variable frequency device) 17 of the compressor 1 is controlled, the rotation speed of the compressor 1 is operated at a variable speed at 30 to 120 Hz, and the air conditioning capacity of cooling and heating is controlled. .

In the air conditioner 20 of this embodiment,
In the RAM or ROM of the indoor control device 13, the fluctuation frequency f relating to the change in the output amount of the controlled object related to the blowing speed of the air that is cooled or heated by the indoor unit B and blown out into the room, and the controlled object. Fluctuation pattern data (fluctuation characteristics) representing the relationship with the change amount of the target output amount is set and stored for each of a plurality of frequency bands of the fluctuation frequency f divided in advance. That is, FIG.
The fluctuation pattern data set in the conventional device, which is represented by the two-dot chain line in FIG.
However, in the apparatus of the present embodiment, the fluctuation frequency f related to the change in the output amount of the controlled object is divided into n regions, and the fluctuation representing the relationship of "1 / f ^k fluctuation" is shown. the pattern data, sets the smaller value to the coefficient k higher frequency of the frequency band, each according to the "1 / f ^k law" fluctuation frequency f defining by applying a large value to the coefficient k as will the frequency band of the low frequency Fluctuation pattern data is set for each frequency band. As an example of a method for obtaining fluctuation pattern data having the relationship of “1 / f ⁱ fluctuation (i = arbitrary positive number)”, there is a method of integrating random number sequence data by a random function using a general-purpose Fourier transform method. . According to this, when a certain time series data is differentiated n times, the power spectrum obtained by this is proportional to f ²ⁿ . In this case, it holds even if n is negative (meaning integration processing). Thus, by integrating n times time-series data of the random number sequence data, it is possible to power spectrum to obtain a pattern data of "1 / f ²ⁿ fluctuation" which is proportional to 1 / f ^2n. Then, considering the case where the data string X at the discretized time interval t is differentiated n times, this is formally converted into an expression corresponding to the integration, and the following expression (1) is obtained. However, the data string X when r = 0
The coefficient of m is 1.

[Equation 1] Here, m: a value representing the position of the data counted from the beginning of the time series data, r: a variable of n and a value from 0 to N, N: the number of frequency band divisions, using a random number sequence as the data sequence X Therefore, Ym expressed by the equation (1) is “1 / f ²ⁿ fluctuation”
It becomes time series data having the relationship of. So N and n
By setting an appropriate value as, fluctuation pattern data having a relationship of “1 / f ⁱ fluctuation” (i = arbitrary positive number) can be obtained. For example, when n = 0 is solved and the equation (1) is solved, Ym becomes “1 / f ⁰ fluctuation” time series data, and when n = 0.5 is calculated, Ym becomes “1”.
/ F fluctuation ”. Further, if n = 1 is calculated, Ym can be obtained as "1 / f ² fluctuation" time series data.

Next, the control operation of the "good morning timer operation" and the "good night timer operation" using the air conditioner 20 having the configuration in which the relationship of "1 / f ^k fluctuation" in FIG. 3 is set will be sequentially described. In the air conditioner 20, the only difference in control between the cooling operation mode and the heating operation mode is that the control target temperature, which will be described later, is set higher or lower than the set temperature. Is. Therefore, for ease of explanation, only the cooling operation mode will be described in the following embodiments. First, a control example of the "good morning timer operation" in the cooling operation mode will be described with reference to the flowchart of FIG. In addition, S shown in FIG. 4 and FIG.
1, S2, S3, ... and S21, S22, S23 ...
.. indicates the operation steps of control. here,
The control of the air conditioner 20 is started from 30 minutes before the set time which is the preset wake-up time (S1, YE
S). Then, the temperature is set to 1.
The control target temperature Tm at that time is set to 5 ° C. higher (S
2) And the fluctuation pattern data of "1 / f fluctuation" is selected and the cooling operation is started (S3, S4). Then, every 5 minutes, the control target temperature Tm is set to 0.
The control of the air conditioner 20 is executed by switching the fluctuation pattern data of the frequency band so that the coefficient k is decreased by 3 ° C and the coefficient k is decreased by 1/6 (S5 to S9). At this time, the average value of the power spectrum relating to the amount of change in the blowing air speed also naturally increases stepwise. FIG. 5 shows the change over time in the average value of the power spectrum relating to the amount of change in the control target temperature Tm and the blowing wind speed. Here, the control target temperature Tm is set to the set temperature T 5 minutes before the set time.
It becomes equal to s and is controlled by the fluctuation pattern data of "1 / f ⁰ fluctuation" at the set time (S
10). Then, after the set time is reached (S7, Y
ES, S10), if the setting of the operation mode is not changed (S11, NO), the coefficient k is incremented by 1/6 every 5 minutes and the fluctuation pattern data is sequentially switched and controlled, and the blowing wind speed is controlled. The average value of the power spectrum regarding the amount of change is gradually reduced (S11 to S1).
5). In this way, after 30 minutes from the set time, the fluctuation pattern data of "1 / f fluctuation" at the beginning of the operation is restored, and the control of the cooling operation mode is continued based on the fluctuation pattern data.

When selecting the power spectrum of the number of revolutions of the indoor blower 7 as the controlled object related to the change amount of the blowing air velocity of the air, it is divided into seven frequency bands as shown in FIG. "1 / f, f ^5/6 , 1 / f ^2/3 ,
1 / f ^1/2 , 1 / f ^1/3 , 1 / f ^1/6 , 1 / f ⁰ ”, and the average value of the power spectrum becomes smaller as the frequency band of the low frequency decreases. The fluctuation of the output frequency of the inverter 8 is controlled by each fluctuation pattern data. At this time, the elevation angle of the louver 10 is kept constant. On the other hand, when the power spectrum of the elevation angle of the louver 10 is selected as the change amount of the output amount of the controlled object, the rotational position of the motor 11 that drives the louver 10 according to the seven fluctuation pattern data shown in FIG. Fluctuation is controlled. In this case, conversely, the rotation speed of the indoor blower 7 is kept constant.
The elevation angle of the louver 10 indicates a rotation angle about the shaft 19 of the louver 10 provided at the air outlet (not shown) of the indoor unit B as shown in FIG.
In the figure, the position (10A) of the louver 10 at the reference angle θ = 90 ° is shown by using a solid line, and the position (1) that is rotationally displaced from the reference angle θ by the displacement angle Δθ (= θ−θ ₁ ).
0B) is indicated by a broken line. That is, the vertical axis of FIG. 7 indicates the power spectrum (d) of the displacement angle (depression angle) of the louver 10.
B) is coordinated according to the equation (2). Power spectrum of displacement angle (dB) = log ₁₀ Δθ / θ (2) As described above, according to the air conditioner 20 of the present embodiment, weak power is obtained from 30 minutes before the set time which is the wake-up time. By using the average value of the spectrum, in addition, a fluctuation stimulus with a long fluctuation period and a large change in the fluctuation frequency with respect to the fluctuation frequency begins to be given, and the room temperature gradually approaches the set temperature while gradually increasing the stimulus. It is possible to wake up the user gently and surely. Then, by the power spectrum of the strongest level at the wake-up time, in addition, the user is awakened by the strong fluctuation stimulus related to the blowing wind speed, which has the shortest fluctuation period and the degree of change is small with respect to the fluctuation frequency. After that, by gradually reducing the average value of the power spectrum and returning the fluctuation pattern data to the original "1 / f fluctuation" relationship, the user feels discomfort that a strong fluctuation stimulus continues for a long time after waking up. To give to.

[0013] Next, in the cooling operation mode
Control example of "only timer operation"
And the graph of FIG. 10 will be described below. First, "Oh
When "Sumi timer operation" starts, control target temperature Tm
Is set equal to the set temperature Ts (S21), and "1 / f

(S22), the cooling operation targets the control target temperature Tm.
Is started (S23). And every 10 minutes,
The control target temperature Tm is increased stepwise by 0.5 ° C.
The coefficient k is increased in steps of 0.5 by 1 / f ^kYu
It is sequentially switched to the fluctuation pattern data of "Ragi" and the result is
As a result, the flatness of the power spectrum related to the amount of change in the blowing wind speed
The average value is also sequentially reduced (S24 to S28). The above
In the case of "good night timer operation", use a timer not shown
The fixed operation time is 1 hour, and in the case of this embodiment,
In this case, the above control should be started 10 minutes before 1 hour after the start of operation.
The target temperature Tm is higher than the set temperature Ts by 2.5 ° C.
As the fluctuation pattern data that is raised to the temperature
"1 / f^3.5It is controlled by the "fluctuation" relationship. And above
When the set operating time (1 hour) has elapsed (S2

It is supposed to be stopped (S29). In addition, the above blowing

When using the power spectrum of the rotation speed of the machine 7,
The relationship for each of the six frequency bands (1 /

/ F^3.5) Is set and the power spectrum of each
Becomes smaller as the average value of
The output frequency of the inverter 8 fluctuates due to the relationship
Controlled. However, at this time, the depression of the louver 10 is the same as above.
The elevation angle is kept constant.

On the other hand, when the power spectrum of the elevation angle of the louver 10 is used as the amount of change in the output amount of the controlled object, the fluctuation pattern data of the six relations shown in FIG. The rotational position of is controlled to fluctuate. In this case, the rotation speed of the indoor blower 7 is kept constant. As described above, according to the "good night timer operation" by the air conditioner 20 of the present embodiment, the room temperature is raised stepwise as the timer time elapses.
This prevents the user from getting cold. At the same time, the average value of the power spectrum related to the amount of change in the blowing wind speed is decreased while the fluctuation cycle of the power spectrum is lengthened and the degree of change with respect to the fluctuation frequency is increased, so that the stimulation due to the change in the blowing wind speed is gentle. Therefore, the blast sound is also reduced without strongly stimulating the user's skin sensation. As a result, the user can be controlled to enter the sleep state gently. In each of the above-described embodiments, as the output amount of the controlled object related to the blowing air speed, the rotation speed of the indoor blower 7 and the elevation of the louver 10 provided at the air outlet (not shown) of the indoor unit B are raised. Although the angle is applied, it is not limited to this. As described above, according to the air conditioner 20 that performs the "good morning timer operation" and the "good night timer operation", in the high frequency frequency band, the level of the amount of change in the blowing air speed of the air is large and the change cycle is short. Fluctuation pattern data suitable for a person who has a strong stimulus, for example, an emotional state when waking up is set. Further, in the intermediate frequency band, fluctuation pattern data in which the level of the amount of change in the blowing air speed is medium and the fluctuation period is medium is set.
Further, in the low frequency band, fluctuation pattern data is set which is comfortable for a person who has a small change level of the blowing air speed and a long change cycle and is weakly stimulating for humans, for example, an emotional state trying to sleep. . Therefore, by performing the air conditioning control using each fluctuation pattern data set for each frequency band as described above,
Depending on the level of the amount of change in the blowing wind speed and the change cycle that each fluctuation pattern data has, it is possible to perform air conditioning control that reflects the stimulus desired by the person according to the emotional state of the person at that time.

[0015]

The first invention is constructed as described above. As a result, it is possible to give a feeling of comfort to a person in the emotional state according to the emotional state of the person. The second invention is constructed as described above. Therefore, for example, it is possible to give a stimulus according to the level of the change amount of the output amount of the controlled object suitable for each person such as a person who is in an emotional state when getting up and a person who is in an emotional state at bedtime. Third
Since the invention of claim 1 is configured as described above,
