Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner having a plurality of indoor units installed in one room.

[0002]

2. Description of the Related Art In order to air-condition a large room, a plurality of indoor units may be installed at intervals. Then, each of these indoor units is individually controlled so that the temperature of the air sucked into the heat exchanger is detected and this becomes the set temperature.

[0003]

In a large room, the air conditioning load varies greatly depending on the position of the room depending on the window, office equipment, distribution of people in the room, etc. Since the temperature of the air sucked into the heat exchanger is detected, it is not possible to accurately detect the temperature at a predetermined position in the room, and the temperature, air volume, and air direction at positions outside the air conditioning range of each indoor unit are controlled. Is difficult to do, so it is easy for parts to become too cold or too warm, and
There is a problem that the temperature, air volume, and wind direction at a predetermined position in the room cannot be controlled to desired values.

[0004]

The present invention has been invented in order to solve the above-mentioned problems, and the gist of the invention is that at least a blower for energizing conditioned air and a blowing air In an air conditioner in which a plurality of indoor units having blow-out louvers for controlling the wind direction are installed in one room at intervals, the temperature setting means and the air volume are installed at desired positions in the room. A plurality of remote controls equipped with setting means, wind direction setting means, room temperature detecting means, and transmitting means for transmitting the set values of the respective setting means and the detected values of the detecting means, and detecting the installation positions of the plurality of remote controllers. And a controller for receiving the outputs from the plurality of remote controllers and the position sensors to adjust the temperature, the air volume, and the wind direction at the installation positions of the plurality of remote controllers. In the air conditioner, wherein the door.

[0005]

According to the present invention, since it has the above-mentioned configuration, it can be set in accordance with the installation positions of the plurality of remote controllers transmitted from the position sensor and the set values and the detected values of the temperature, air volume, and wind direction transmitted from the plurality of remote controllers. The temperature, the air volume, and the air direction of the conditioned air blown out from the plurality of indoor units are controlled.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT One embodiment of the present invention is shown in FIGS. As shown in FIG. 1, a plurality of (three in the figure) indoor units A, B, C are installed on a ceiling 2 of a room 1, and these indoor units A, B, C energize conditioned air. Blower A1, for
B1, C1 and blowout louver A to regulate the wind direction
It is equipped with 2, B2 and C2. Further, a plurality of remote controllers 3, 4, 5, 6 are installed in the room 1. The remote controller 3 is on the wall surface, the remote controller 4 is near the office equipment 11, the remote controller 5 is on the office desk 12, and the remote controller 6 is It is installed on the meeting desk 13.

Each of these remote controllers 3, 4, 5, 6 is shown in FIG.
As shown in, the temperature setting means 22, the air volume setting means 20, the wind direction setting means 21, a display means 19 for displaying these set values, a temperature detecting means (not shown), the set values of the respective setting means 20-22 and the temperature detection. A transmission means for transmitting the detection value of the means is provided.

A plurality of (two in the figure) position sensors 7 and 8 are installed in the chamber 1. The position sensors 7 and 8 detect the installation positions of the remote controllers 3, 4, 5 and 6. It receives the information transmitted by each remote controller 3, 4, 5 and 6 and transmits it to the controller built in the outdoor unit 10.
Reference numeral 9 denotes the conditioned air generated by the outdoor unit 10 for each indoor unit A, B,
It is a duct sent to C. A control block diagram is shown in FIG. 3, and the information transmitted from the remote controllers 3 and 4 is the position sensor 7.
The information received by the remote controller 5 and transmitted from the remote controllers 5 and 6 is received by the position sensor 8. The position sensor 7 is a remote controller 3, 4
The installation position of and the information received from the controller 11
Send to. The position sensor 8 transmits the installation positions of the remote controllers 5 and 6 and the information received from them to the controller 11. The controller 11 is a blower A1 for each indoor unit A, B, C.
B1, C1 and blowout louvers A2, B2, C2 and the outdoor unit 10 are controlled by outputting them to control the temperature, air volume, and wind direction at the positions where the remote controllers 3, 4, 5, 6 are installed. Maintain the temperature, air volume, and wind direction set to 5 and 6.

However, in the arrangement shown in FIG. 1, the remote controller 3 has the air volume set to "medium" and the wind direction set to "normal".
Since the remote controller 4 is installed near the OA equipment 11, the air volume is set to "strong" and the wind direction is set to "direct", and the remote controller 5 is set to "weak" and "indirect" in accordance with the office work. Is set. Then, the left louver of the blowing louver A1 is directed so that a part of the blowing air hits the remote controller 3, and the right louver is directed so that the blowing air hits the OA equipment 11 directly. The louver on the right side of the blowing louver B2 is directed so that the blowing wind hits the remote controller 4. And
The air volume hitting the remote controller 3 is "medium", the wind blown from the indoor units A and B hits the remote controller 4, and the air volume is "strong", and the air quantity hitting the remote controller 5 is "weak".

Since the remote controller 6 is located at the conference corner, the air volume is set to "strong" and the wind direction is set to "normal". The blowout louver C2 is oriented so as to hit the entire area around the remote controller 6, and the remote controller 6 is blown by the air blown from the indoor units B and C, so that the air volume becomes “strong”.

In the above embodiment, the conditioned air generated by the outdoor unit 10 is blown from the indoor units A, B, C to the room 1 through the duct 9, but the indoor units A, B, C are respectively supplied. It is also possible to individually control the temperature of the conditioned air flowing through each heat exchanger by disposing heat exchangers and adjusting the amount of refrigerant supplied to these heat exchangers.

[0012]

According to the present invention, a plurality of indoor units are installed according to the installation positions of a plurality of remote controllers transmitted from the position sensors and the temperature, air volume, wind direction set values and detected temperatures transmitted from the plurality of remote controllers. By adjusting the blower and the blowout louver, the temperature, the air volume, and the air direction at the installation positions of the plurality of remote controls are controlled. As a result, it is possible to satisfy different requirements at the installation positions of the plurality of remote controllers, and it is possible to prevent partial overcooling or overheating.
