Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner, and more particularly to
The present invention relates to an air conditioner that controls the indoor thermal environment in consideration of the effect of radiant heat due to solar radiation.

[0002]

2. Description of the Related Art Conventionally, in the thermal environment control of an air-conditioned room such as an office, only the temperature and humidity are controlled, and the air conditioner and other heat sources are controlled to keep them constant. However, the original purpose of air conditioning is not to provide a constant temperature and humidity in the room, but to provide a comfortable thermal environment to the occupants.

[0003]

However, the conventional air conditioner has a problem in that it is not taken into consideration, although the radiation environment caused by solar insolation has a great influence on the thermal sensation of the person in the room. That is, the temperature inside the wall of the air-conditioning room, which directly affects the radiation environment of the air-conditioning room, and the effect of solar radiation entering the air-conditioning room through the window, are also captured only as temperature changes. As a result, when the walls and windows of the air-conditioning room are heated to a high temperature by strong sunlight, the temperature inside the walls rises after a certain time, but there is a time delay, and the radiation of heat from the walls and windows The convection deteriorates the thermal environment of the person in the room near the wall. Further, for a person in the room near the window of the air conditioning room, the thermal sensation greatly changes depending on the amount of solar radiation directly entering the air conditioning room through the window. As described above, in the control that targets only the temperature and humidity in the room like the conventional air conditioner, even if the temperature in the room is controlled according to the setting, it is not possible to provide the occupants with a comfortable thermal environment. .

The present invention has been made in view of such circumstances, and makes the entire room a comfortable thermal environment by performing air conditioning control in consideration of the effect of solar radiation for each air conditioning zone that divides the air conditioning room. It is an object of the present invention to provide an air conditioner that can be used.

[0005]

In order to achieve the above-mentioned object, the present invention divides an air-conditioning room into a plurality of air-conditioning zones, and performs air-conditioning for each divided air-conditioning zone, and each of the air-conditioning zones. Indoor temperature measuring means for measuring the air temperature,
Insolation measuring means for measuring the amount of solar radiation in the building of the air conditioning room, the air temperature of each air conditioning zone measured by the indoor temperature measuring means and the solar radiation measured by the solar radiation measuring means, in advance, The solar radiation influence degree for each air conditioning zone is calculated by adding the inputted structural information of the building and standard solar radiation intensity information according to the season and date, and the air conditioning set temperature for each air conditioning zone is taken into consideration in consideration of the solar radiation influence degree. And a control means for controlling the air conditioning conditions of the air conditioning means so that each of the air conditioning zones has the air conditioning set temperature corrected by the arithmetic means.

[0006]

According to the present invention, the air-conditioned room is divided into a plurality of air-conditioned zones, and the air temperature of each air-conditioned zone is measured by the indoor temperature measuring means and input to the computing means. Further, the amount of solar radiation to the building forming the air-conditioning room is measured by the solar radiation amount measuring means and input to the computing means. In addition, the calculating means adds the measured air temperature and the amount of solar radiation to the structure information of the building and the standard solar radiation intensity information according to the season and date, which are pre-input to the calculating means, and the solar radiation effect for each air conditioning zone. The air-conditioning set temperature is corrected for each air-conditioning zone in consideration of the degree of solar radiation influence. Then, the control means controls the air conditioning conditions of the air conditioning means so that each of the air conditioning zones has a corrected air conditioning set temperature. As a result, since it is possible to perform air conditioning control in consideration of the effect of solar radiation for each air conditioning zone, it is possible to make the entire air conditioning room a comfortable thermal environment.

Further, an outside air temperature measuring means for measuring the outside air temperature of the building is provided to correct the air conditioning set temperature for each air conditioning zone in consideration of the temperature difference between the outside air and each air conditioning zone in addition to the influence of solar radiation. . As a result, the change in heat exchange between the outside air and each air conditioning zone can be accurately grasped through the wall of the building according to the change in the outside air temperature for one day, so that more detailed correction can be performed. it can.

As shown in FIG. 1, the sun 50 is located in the southeast direction of the building 12 to be air-conditioned, and the air-conditioning zones C and D in the air-conditioning room 10 have the sun rays 5
Since 2 hits directly, the amount of solar radiation is large, and the amount of solar radiation in the air conditioning zone A is small. Therefore, when the air-conditioning room 10 is air-conditioned only with temperature and humidity like a conventional air-conditioning apparatus, people in the air-conditioning zones C and D feel hot and people in the air-conditioning zone A feel cold. Therefore, in the air conditioner of the present invention, the air conditioning control described below is performed.

That is, the solar radiation amount measuring sensor 27, the outside air temperature measuring sensor 40 and the indoor temperature measuring sensors 28, 3
The solar radiation amount, the outside air temperature, and the air temperature of each air conditioning zone are measured at 0, 32, and 34, and the measured data are sequentially input to the input unit 42 of the thermal environment control device 26.

As a result, each air conditioning zone A, B, C, D
Air-conditioning control can be performed in consideration of the degree of influence of insolation and the outside air temperature for each, so that the entire air-conditioned room 10 can be provided with a comfortable thermal environment. Therefore, the person in the air conditioning room 10 can feel a good and stable thermal sensation regardless of where the air conditioning room 10 is.

As a result, the person in the air conditioning room can feel a good and stable thermal sensation regardless of where he / she is in the air conditioning room.

Therefore, even if the temperature of the air-conditioning room is controlled according to the setting as in the conventional air-conditioning system in which only the temperature and humidity are controlled, it is too hot at the location of the person in the room, for example, near the window where there is strong sunlight. The disadvantage of being too cold in a place away from the window can be eliminated.
