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, in the conventional method, even if the temperature is distributed above and below the air-conditioned space due to air conditioning in the air-conditioned space, and as a result, the PMV values are distributed above and below the air-conditioned space, detection of one location is performed. The PMV value can only be set to a comfortable area centering on the place, and the PMV value cannot be set to be neutral in the entire living area, and there is a drawback that air conditioning is performed more than necessary.

Further, since the environmental elements in the living area are directly detected, the installation place of the detecting means is restricted and the structure becomes expensive.

The present invention solves the above-mentioned conventional problems. The PMV value in the room is controlled so as to be in the comfortable area, and the conventional detection means is used to provide an inexpensive PMV value in the living area due to the vertical temperature distribution. It is an object of the present invention to provide an air conditioner that quickly and accurately controls the PMV value in the living area to a comfortable area even if there is a difference in the detected PMV value.

[0008]

In order to achieve this object, the air conditioner of the present invention changes the air-conditioning means for cooling or heating the inside of the room, the indoor blower for circulating the indoor air, and the wind direction of the blown-out air. A wind direction changing means, a fuzzy room temperature inference means for fuzzy inferring the room temperature in the living area from the wind direction, the air volume, and the operation mode, and a living area PMV value calculating means and a living area PMV for calculating the PMV value in the living area using the inferred room temperature as a parameter. A PMV value cooling / heating control means for controlling the cooling / heating means so that the value becomes neutral is provided.

Further, the living area is divided into a plurality of zones, and a zone for fuzzy inference of the room temperature distribution above and below the air-conditioned space is obtained from a plurality of zone-based wind direction changing means corresponding to each zone, the air volume, the operation mode and the average wind direction for each zone. The fuzzy room temperature inference means PMV value calculation means and the zone PMV value calculation means for calculating the PMV value of the living area using the inferred room temperature as a parameter.

[0010]

With the above-described structure, the present invention uses the fuzzy room temperature inference means based on the limited input conditions that can be detected by the air conditioner body even when there is a temperature distribution above and below the air-conditioned space, that is, from the wind direction, air volume, and operation mode. The room temperature of the living area is fuzzy inferred, the PMV value of the living area is calculated using the inferred room temperature as a parameter, and the cooling / heating means is controlled so that the PMV value of the living area becomes neutral. Even in this case, the PMV value in the living area can be controlled to be neutral.

Further, even if the living area is divided into a plurality of zones, the blowing air direction changes for each zone, and the vertical temperature distribution of the air-conditioned space occurs, resulting in the distribution of PMV values in the air-conditioned space, the operating mode and the air volume. And fuzzy inference of the room temperature of the living area by the average wind direction for each zone, the PMV value of the living area is calculated using the inferred room temperature as a parameter, and the cooling / heating means is controlled so that the PMV value of the living area becomes neutral. Even if the blowing wind direction changes for each zone and the PMV values are distributed, the optimum operation for neutralizing the PMV values in all the residential areas becomes possible, and the PMV values can be effectively neutralized in the entire residential areas. .
