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 automatically controlling an indoor environment so that a occupant can feel comfortable.

[0002]

2. Description of the Related Art A conventional air conditioner is controlled to keep a room temperature within a certain temperature range, but it should be designed so as to keep the sensation of warmth and coolness of a person living therein. In order to realize such comfort, a PMV comfort index has been proposed, and Japanese Patent Application Laid-Open No. 2-178555 and Japanese Patent Application Laid-Open No. 2-2 disclose control of an air conditioner based on this index.
There is one disclosed in Japanese Patent No. 42037.

PMV is translated as an average expected thermal sensation report,
It is one index to evaluate the comfort of thermal environment and was proposed by Professor Whanger of the Technical University of Denmark, 198
It was internationally standardized as ISO-7730 in 4 years. This PMV is a function of temperature, humidity, radiant temperature and air velocity as environmental factors, and activity amount and clothing amount as human body factors, and can be obtained from these values by the formula described in ISO-7730. . And this P
MV value 0 is neutral and comfortable, 3 is hot, 2 is warm, 1 is slightly warm, -3 is cold, -2 is cool,
-1 is defined as a little cool. The description of the formula and the calculation method will be omitted.

The one disclosed in Japanese Patent Laid-Open No. 2-178555 discloses that the activity amount and the clothing amount, which are factors of the human body side of PMV, are expressed by a fuzzy set to calculate an optimum PMV value so that the PMV value becomes neutral. The air conditioner is controlled by using temperature and humidity as control parameters. In addition, Japanese Patent Laid-Open No. 2-2
In the one disclosed in Japanese Patent No. 42037, a detection means for detecting temperature, humidity and radiation temperature is installed in a living area, and a PMV value is calculated from a setting means for setting an air flow velocity, an amount of activity and an amount of clothes, and the PMV value is Various air conditioners are cooperatively controlled using the temperature as a control parameter so as to be neutral.

[0005]

However, the conventional method cannot always realize a comfortable thermal environment for the user in terms of the user's preference for the thermal environment and the accuracy of PMV value calculation. On the other hand, although the control target value is corrected by the temperature sensation input, it is not possible to input the optimum temperature sensation according to the degree to which the user feels hot or cold, and the temperature sensation input operation is frequently performed each time the vehicle is driven. It was accompanied by the inconvenience of being necessary.

The present invention solves the above-mentioned conventional problems, and realizes a comfortable thermal environment in which the user's preference and PMV value calculation accuracy are taken into consideration, and the inconvenience caused by the complexity of the thermal sensation input operation is eliminated. The purpose is to provide a harmony machine.

[0007]

In order to achieve this object, an air conditioner of the present invention comprises a cooling / heating means for cooling or heating an interior of a room, and a PMV value calculation means for sequentially calculating a PMV value of a living area. A temperature sensation input means capable of inputting coolness or warmness in multiple stages according to the user's feeling of hot and cold, a temperature sensation input correction amount determination means for determining the PMV value correction amount by the temperature sensation input, and Neuron generating means for generating a neuron as a teacher signal by associating the sensed input correction amount with the room temperature, the outside air temperature at the time when the sensed temperature is input, the elapsed time from the start of operation, and the PMV value, and a fixed time after the PMV value correction. A monitoring section is provided, and when a temperature sensation is input within the same monitoring section, a neuron integrating means for integrating and changing the correction amount of the neuron generated by the neuron generating means, The PMV value correction neural network that determines the PMV value correction amount based on the neurons, and the PMV value calculated by the PMV value calculation means are corrected by the temperature sensation input correction amount determination means and the PMV value correction neural network. And corrected PMV
A cooling / heating control means for controlling the cooling / heating means so that the value is stable within the comfortable range.

[0008] In addition, PMV can be input by a multi-step temperature sensation input operation.
A temperature sensation input correction amount determining means for determining a correction amount, a correction amount determined by the temperature sensation input correction amount determining means, and a room temperature, an outside temperature, an elapsed time from the start of operation, and a PMV value as a teacher signal. In the same monitoring section, a neuron generating unit that generates a neuron, a PMV value correction neural network that is composed of a plurality of neurons generated by the neuron generating unit, and outputs the result of arithmetic processing of the output value of each neuron as a correction amount, In the above, when the temperature sensation input operation determines the correction amount by the temperature sensation input correction amount determining unit, the neuro correction inhibiting unit does not perform the correction determined by the PMV value correcting neural network.

[0009]

According to the present invention, each time a temperature sensation input operation is performed, a neuron that correlates the correction amount with the room temperature at that time, the outside temperature, the elapsed time from the start of operation and the PMV value is generated. Even if a sensation input operation is not performed, it is not necessary to frequently input the sensation because the neuron determines the optimum correction amount according to the state of factors such as room temperature and outside temperature.

Further, since the correction amount determined by the neuron and the correction amount by the temperature sensation input are integrated by providing a constant monitoring section, the number of generated neurons can be small,
It is possible to eliminate the inconvenience of frequent temperature sensation input operations with a small storage capacity.

Further, if the warm sensation is first input within the same monitoring section, the correction determined by the neuron is prohibited, so that the correction not intended by the user is not performed and the user does not feel uneasy. .
