The conventional air conditioner is
When the same number of people are present in both areas A and B in the room, the flow of the airflow is as shown by the arrows in FIGS. 8 and 9,
There was a problem that the wind, as shown by the diagonal lines, was hard to reach, and there were areas where it was difficult to air-condition. Further, there is a problem in that the increase in the air-conditioning floor area leads to an increase in the rise time and energy of the air conditioner in a region where people are present, and a decrease in comfort, so that the expected effect cannot be obtained.

The present invention has been made to solve the above problems, and when the distribution of people in the room is uniform, it is possible to realize air conditioning with high temperature uniformity and the distribution of people in the room. When there is a bias in the room, the object is to divide the room into a plurality of areas and obtain an efficient air conditioner without being affected by other areas.

SUMMARY OF THE INVENTION An air conditioner according to the present invention is provided with an air flow direction changing plate provided at an air air outlet so as to blow out air jets from an air outlet at a predetermined angle in a direction in which they face each other and collide with each other. The wind direction change control means for controlling the change plate and the wind speed control means for controlling the amount or speed of the blown air are provided.

[0008]

In the air conditioner according to the present invention, air blown out from a plurality of air outlets collides with each other so that the air conditioners serve as air curtains in opposite areas, and the areas covered by the air conditioners are influenced by other areas. Without efficient air conditioning.

The infrared ray radiated from the human body in the room or office equipment is detected by the detecting means B3b. Then, in step 2, the signal is amplified by the amplification means 4 and the first signal line 4
It is output to the comparison means 5 through c and the second signal line 4d.
Then, in step 3, the third signal line 6a and the fourth signal line 6b are passed through the filter 6 for time-averaging abrupt changes in the environment in which people such as offices and stores enter and exit, and rapid movements. Is output to. Then detected by comparing the reference value the presence or absence of such person or office equipment in standard values comparing means 5a and have your <br/> to step 4.

When both signals from the third signal line 6a and the fourth signal line 6b input from the filter 6 in step 4 do not satisfy the reference value, the process proceeds to route 1 and the blown winds face each other. Direction changing plate control means 8a, so that the air is blown out under the same conditions with the preset blowing angle and strength.
A signal is issued to 8b. Then, in step 41, the first and second units 9a, 9b are both adjusted to blow out at the same preset angle. Next, step 4
At 2, the air volume and speed are controlled so that both the first and second units 9a and 9b are weak winds, and at step 43, the suction area is controlled so that both the first and second air suction ports 13a and 13b are fully opened. To do.

If either or both of the signals from the third signal line 6a and the fourth signal line 6b output from the filter 6 in step 4 satisfy the reference value, the amplified signal in step 5 is set.
