DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner for automatically controlling the indoor environment so that residents are comfortable.

[0002]

2. Description of the Related Art A conventional air conditioner is controlled so as to maintain a room temperature within a certain temperature range. However, it should be controlled so as to maintain a comfortable and warm feeling of a person living therein. In order to realize such comfort, a comfort index called PMV is proposed, and based on this index, an air conditioner is controlled as disclosed in Japanese Patent Application Laid-Open Nos. 2-178555 and 2-2.
No. 42037, for example. PMV (Pre
Dictated MeanVote is translated as an average expected thermal sensation report and is one index for evaluating the comfort of thermal environment. It was proposed by Prof. Whanger of the Technical University of Denmark, and was internationally standardized as ISO-7730 in 1984. It is a thing.

[0003] This PMV is a function of temperature, humidity, radiation temperature and air flow velocity which are environmental elements and the amount of activity and clothes which are human body elements.
730. It is assumed that the PMV value 0 is neutral and comfortable, 3 is hot, 2 is warm, 1 is slightly warm, -3 is cold, -2.
Is defined as cool and -1 is defined as slightly cool. Also,-
In the range of 0.5 <PMV value <0.5, 90% of the persons are comfortable, and this range is defined as the comfortable range. The description of the formula and the calculation method is omitted.

[0004] Japanese Patent Application Laid-Open No. 2-178555 discloses a fuzzy set expressing the amount of activity and the amount of clothing, which are factors on the human body of a PMV, to calculate an optimal PMV value so that the PMV value becomes neutral. To control the air conditioner.
Further, those described in JP-A-2-242037 are
Detecting means for detecting temperature, humidity, and radiation temperature are installed in the living area, and PMV values are calculated from setting means for setting the air flow velocity, the amount of activity, and the amount of clothing, and various air conditioners are set so that the PMV value becomes neutral. , And corrects the control target value set in the comfortable range by inputting the warmth or cold feeling.

[0005]

However, in the conventional method, since the calculated PMV value or its standard is not displayed, the user does not know whether the current PMV value is within the range of the comfortable region. . Therefore, PMV
If the value is not within the range of the comfortable area, and if the input of the thermal sensation is made, is it the input of the current thermal sensation as it is,
Since it cannot be determined whether the PMV value has been input predictively in anticipation of the feeling of comfort when the PMV value falls within the range of the comfortable region, it is not always possible to correct the PMV value correctly.

[0006] Also, even if the user finds that the current PMV value is not within the range of the comfortable area, the PMV
In anticipation of the feeling of comfort when the value falls within the range of the comfort area, performing the predictive warmth input to be comfortable
Except for the case described below, it is difficult and there is a problem that it is more likely to be an uncomfortable thermal environment.

However, even when the PMV value is not within the range of the comfortable region, the PMV value is "cold" when the cooling operation is performed on the hot side, or the heating operation is performed when the PMV value is on the cold side. If the user receives a hot feeling of “hot”, it is judged that it is the user's feeling at that time and the PM
The V value must be corrected.

In addition, there has been a drawback such as inconvenience that a user must frequently input a warm feeling every time the vehicle is driven. The present invention solves the above conventional problems,
Provided is an air conditioner that can accurately correct a PMV value by a thermal sensation input regardless of whether or not the current PMV value is within a comfortable region and eliminates inconvenience due to frequent operations of the thermal sensation input. With the goal.

[0009]

In order to achieve this object, an air conditioner according to the present invention comprises: a cooling / heating means for cooling or heating a room; a PMV value calculating means for sequentially calculating a PMV value in a living area; A warm feeling input means for inputting a user's feeling such as hot or cold, a correction amount specifying means for determining a correction amount based on the input of the warm feeling input means, and a PMV value calculated by the PMV value calculating means. PMV value correction means for correcting by a correction amount determined by the correction amount designating means,
A thermal sensation input reception prohibiting unit that does not receive the thermal sensation input when the PMV value is not within the range of the comfortable region;
Cooling and heating control means for controlling the cooling and heating means so that the value is stabilized within the range of the comfortable region.

A cooling / heating means for cooling or heating the room, and a PMV for sequentially calculating a PMV value in the living area by calculation
Value calculating means, warm feeling input means for inputting a user's feeling such as hot or cold, correction amount specifying means for determining a correction amount based on the input of the warm feeling input means, and PMV value calculating means. PMV value correction means for correcting the obtained PMV value by the correction amount determined by the correction amount designating means;
When the value is not within the range of the comfortable area, the PMV value is not accepted when the PMV value is on the hot side, or when the PMV value is on the cold side. The air conditioner includes a reception prohibiting unit and a cooling / heating control unit that controls the cooling / heating unit so that the PMV value is stabilized within a comfortable range.

[0011] The correction amount designating means includes a warm feeling input amount designating means for determining a correction amount corresponding to an input by the warm feeling input means, and a correction amount determined by the warm feeling input amount designating means and a warm feeling input. Neuron generation means for generating neurons by relating factors such as room temperature and outside air temperature at the time, and a plurality of neurons generated by the neuron generation means, the output values of each neuron being arithmetically processed and the correction amount And a correction amount learning neural network that outputs a correction amount.

Further, a neuron generation order storage means for recording a generation order of a plurality of neurons generated by the neuron generation means, and an oldest neuron stored by the neuron generation order storage means when the number of neurons exceeds a predetermined value. Neuron replacement means for replacing the latest neuron generated by the neuron generation means.

[0013]

According to the present invention, when the PMV value is not within the range of the comfortable region, the input of the thermal sensation is not received by the thermal sensation input acceptance prohibiting means.
If the value is not within the range of the comfortable region, the user may receive the sense of warmth at that time to make an erroneous correction, or a predictive and anticipated feeling of comfort when the PMV value falls within the range of the comfortable region. It is possible to prevent an uncomfortable thermal environment from being received as a result of receiving a thermal sensation input.

On the other hand, when the PMV value is not within the range of the comfortable area, the mode-linked warm feeling input reception prohibiting means inhibits the PMV value.
When the value is on the hot side (during cooling operation), it is not possible to receive the warmth input of "hot" or when the PMV value is on the cold side (during heating operation), it is not possible to receive the warmth input.
When the value is not within the range of the comfortable area, the temperature of the user at that time is accepted and incorrect correction is performed, or a predictive warmth input is not accepted. If a “hot” temperature sensation is input during the heating operation, a correction can be made.

Further, each time the warmth input operation is performed, a neuron is generated in which the correction amount is associated with the factors such as the room temperature and the outside air temperature at that time, so that the room temperature and the room temperature are obtained even if the warmth input operation is not performed. Since the neuron determines the optimum correction amount according to the state of factors such as the outside temperature, it is not necessary to frequently perform a warmth input operation.

Further, since the oldest neuron is replaced by the latest one when the number of neurons generated by the neuron generating means becomes a predetermined value or more, the inconvenience of frequently inputting a warm feeling with a small storage capacity is eliminated. be able to.

Hereinafter, components having the same configuration as in FIG. 1 are denoted by the same reference numerals, and description thereof is omitted.

An operation example of the air conditioner having the above configuration will be briefly described with reference to the drawings. In the example of FIG. 2, similarly to the first embodiment, the air volume is set to “strong”, the activity amount is “light”, and the clothing amount is “winter clothes”. In this state, the PMV value calculated by the PMV value calculating means 1 is In the case of −1.5, in this state, the PMV value is out of the comfortable area on the negative side.

At this time, since the reception of the “cold” side thermal sensation input is prohibited by the PMV value-linked thermal sensation input reception prohibiting unit 35, even if the user operates the thermal sensation input unit 8 to the “cold” side, the temperature is not affected. The sense input is not accepted, and the display on the warm sense monitor 17 does not change. However, when the user operates the thermal sensation input means 8 on the “hot” side, the acceptance of the thermal sensation input is permitted, the input equivalent amount is displayed on the thermal sensation monitor 17 to correct the PMV value, and 12 performs cooling or heating operation based on the corrected PMV value. And P

Not accepting PMV value-linked warmth input acceptance inhibiting means 35
And a comfort sign 11 illuminated when the PMV value is within the comfort range, and a cooling / heating control means 1 for controlling the cooling / heating means 12 so that the PMV value is stabilized within the comfort range.
Therefore, when the PMV value is not within the range of the comfortable area, the comfort sign 11 is turned off, and when the PMV value is on the hot side (during the cooling operation), “hot” or the PMV When the value is on the cold side (during heating operation), it is prohibited to accept the "cold" temperature sensation input,

The warm feeling input amount specifying means 37 specifies a correction amount corresponding to the input amount of the warm feeling input means 8, and the neuron generating means 38 calculates the correction amount and the room temperature, the outside air temperature and the PMV value at the time of the warm feeling input. One associated neuron is generated in the correction amount learning neural network 41.

The neuron generation order storage means 39 stores the generation order of the neurons generated by the neuron generation means 38, and the neuron replacement means 40 determines the latest neuron as the oldest neuron when the number of generated neurons becomes five or more. Perform the replacement operation. The correction amount learning neural network 39 is composed of a plurality of neurons generated by the neuron generation means 38 (the number of hidden neurons described below is 5 or less), and is sequentially fired by inputting the room temperature, the outside air temperature, and the PMV value. The average value of the output of the neuron is output to the PMV value correction means 10 as a correction amount. Note that, when there is a thermal sensation input, the correction amount specifying means 36 outputs the output of the thermal sensation input amount specifying means 37 to the PMV value correcting means 10 as it is. Reference numeral 42 denotes an outside air temperature detecting means for detecting an outdoor air temperature. Numeral 34 denotes a thermal sensation input unit which prohibits the reception of a thermal sensation input. In this case, a signal for prohibiting the reception of the thermal sensation input is output to the thermal sensation input specifying means 37. Hereinafter, FIG.
Components having the same configuration as those described above are denoted by the same reference numerals and description thereof is omitted.

An operation example of the air conditioner having the above configuration will be briefly described with reference to the drawings. 6A and 6B are conceptual diagrams showing the relationship between one neuron generated in the correction amount learning neural network 41 by the neuron generation means 38 and input / output conditions.

Reference numeral 5 denotes first, second, and third input layer neurons for inputting a room temperature X1, an outside temperature X2, and a PMV value X3, respectively. Numeral 46 denotes the neuron generating means 3 at the time of the first warm sensation input.
8, the first hidden neuron outputs a warm feeling input correction amount Y1 described later when it is in a firing state. 4
Reference numeral 7 denotes an output layer neuron which inputs the warmth input correction amount Y1 of the first intermediate layer neuron 46 and outputs an average value thereof (in this case, Y1 is output). The output layer neuron 47 is 1
Individual. FIG. 6B shows that the first intermediate layer is a neuron 46.
The output Y1 is represented by the following equation.

Y1 = A · f (X) X = Σwixi−T f (X) is a threshold function (f (X) = 1 (X ≧ 0), f
(X) = 0 (X <0)), A is a warmth input correction amount determined by the warmth input amount designating means 37 when the first hidden neuron 46 is generated, and It is stored in the neuron 46. W1, W2, and W3 are connection weights for the input signal, and T is a threshold value, which is determined by the neuron generation means 38 when generating neurons.
When X ≧ 0, the neuron is fired. The intermediate layer neurons are generated one by one by a warm sensation input operation, and a maximum of five intermediate layer neurons are configured by five operations. The neurons generated by the fifth and subsequent warmth input operations are replaced by the neuron replacement means 40 with the oldest neurons in the generation order of the intermediate layer neurons stored by the neuron generation order storage means 39. On the other hand, in the initial state in which the warmth input has not been operated even once, no neuron exists in the intermediate layer of the correction amount learning neural network 41, and there is no connection from the input layer to the output layer. For this reason, even if an input signal comes in from the input layer, the output layer remains at 0.

Reference numerals 46, 48, 49, 50 and 51 denote first, second, third, fourth and fifth hidden neurons generated by five or more warm sensation input operations. The output layer neuron 47 outputs, as a correction amount, the average value of the outputs (Y1 to Y5) of the intermediate layer neurons in a fired state according to the condition of the input signal. For example, the first and second hidden neurons 4
When 6, 48 are in the firing state, the output layer neuron 47 outputs (Y1 + Y2) / 2, and when all the hidden neurons are in the firing state, (Y1 + Y2 + Y3 + Y4 +
Y5) / 5 is output.

[0031] Figure 8 is Ri block diagram der of an air conditioner of the fourth embodiment, the third temperature sensitive input acceptance prohibition hand in the embodiment of
In place of step 34, PMV value-linked warmth input acceptance prohibiting means 3

As described above, according to the third and fourth embodiments, the correction amount designating means 36 determines the correction amount corresponding to the input by the thermal sensation input means 8,
A neuron generating means 38 for generating a neuron by associating the correction amount with a room temperature, an outside air temperature and a PMV value at the time of input of a warm feeling, and a generation order of a plurality of neurons generated by the neuron generating means 38 are recorded. A neuron generation order storage means 39, a neuron replacement means 40 for replacing the oldest neuron stored by the neuron generation order storage means with the latest neuron when the number of neurons becomes five or more, and a plurality of generated neurons. Since the correction amount learning neural network 41 outputs a value obtained by averaging the output values of the neurons as a correction amount, the correction amount and the room temperature, the outside air temperature, PM
A neuron correlated with the V value is generated, and the neuron determines an optimal correction amount based on the room temperature, the outside air temperature, and the state of the PMV value even if the warmth input operation is not performed, and preempts the warmth input operation. Therefore, it is not necessary to frequently perform a warmth input operation.

When the number of neurons generated by the neuron generating means 38 becomes five or more, the oldest neuron is replaced with the latest neuron. Therefore, the correction amount learning neural network 41 can be constructed with a small storage capacity, and the temperature is frequently increased. Inconvenience of performing a feeling input operation can be eliminated.

In the above embodiment, the input conditions are the room temperature, the outside air temperature and the PMV value. However, conditions such as a change in the PMV value and the elapsed time after the start of operation are added to the input conditions, or as another input condition. The same effect can be expected. In the other embodiments, the operation example during the heating operation has been described, but the operation example during the cooling operation is also the same. Furthermore, although the cooling / heating means 12 is constituted by a refrigeration cycle, the same effect can be expected by using this as another cooling / heating means such as a radiation cooling / heating panel. A similar effect can be expected if the PMV value calculating means is configured to input related conditions other than the input conditions shown in the embodiment and learn by a neural network to infer the PMV value.

If the PMV value is not within the range, the mode-linked warm feeling input reception prohibiting means prevents the PMV value from being within the comfortable region. When the PMV value is on the hot side (during cooling operation), the "hot" or PMV value When the user is on the cold side (at the time of heating operation), the user does not receive the input of the feeling of "cold", and if the PMV value is not within the range of the comfortable area, the user receives the feeling of the user at that time. Incorrect correction or predictive Not to accept the warm feeling of input, on the other hand, there is an effect that when the temperature sense input of the "hot" has been made "cold" or during the heating operation at the time of the cooling operation can be corrected.

Further, in the air conditioner of the present invention, the correction amount designating means determines the correction amount corresponding to the input by the thermal sensation input means and the thermal sensation input amount specification means. A neuron generating means for generating a neuron by associating a correction amount with a factor such as a room temperature and an outside air temperature at the time of input of a feeling of warmth; and a plurality of neurons generated by the neuron generating means. It is characterized by a correction amount learning neural network that outputs the result of the arithmetic processing of the value as a correction amount. The neuron can determine the optimal correction amount depending on the state, and there is no need to frequently perform a warmth input operation.

In the air conditioner of the present invention, the neuron generation order storage means for recording the generation order of the plurality of neurons generated by the neuron generation means, and the neuron generation order storage means when the number of neurons becomes a predetermined value or more. And a neuron replacing means for replacing the oldest neuron with the latest neuron generated by the neuron generating means, thereby eliminating the inconvenience of frequently inputting a warm feeling with a small storage capacity. be able to.
