When the operation button 11 of the remote controller 3 is pressed in the above structure, a signal is sent from the signal transmitter 4 of the remote controller 3 to the signal receiver 5 of the air conditioner 2, and the start command 27 shown in FIG. A series of operations is started.

Next, by pressing the preset button 12 of the remote controller 3, the first preset command 28 operates,
The size of the air-conditioned room 1 is on standby. As the dimensions of the air-conditioned room, a value measured in advance is input from the remote controller 3.
The width (w), the depth (d), and the height (h) are input to the setting units 14, 15 and 16, respectively. The respective values are displayed on the segments 20a, 20b, and 20c of the display unit 20. This value is processed by the air-conditioned room size input command 29. Next, by pressing the preset button 12 of the remote controller 3 again, the second preset command 30 is operated, and the air conditioner 2 is in a state of waiting for position input. For the position of the air conditioner 2, a value measured in advance is also input from the remote controller 3. Setting units 14, 15 and 16
, The relative positions a, b, and c of the reference point (s) of the air-conditioning apparatus 2 with respect to the plane (P) are input.
The respective values correspond to the segments 20a, 20 of the display unit 20.
b and 20c. This value is processed by the air conditioner position input command 31. Next, using the setting units 17, 18, and 19 of the remote controller 3, the target room temperature, air volume,
And wind direction respectively. This is processed by the instruction 32, and the respective values are displayed on the segments 20a, 20b, and 20c of the display unit 20.

Next, the value of the room temperature detector 9a is fetched by the command 33. In the command 34, the target room temperature set in the command 32 and the room temperature taken in in the command 33 are compared, and it is determined whether the air conditioner 2 is to be heated or cooled. At this point, the operation of the air conditioner 2 is started based on the above settings.

Next, when the automatic button 13a of the remote controller 3 is pressed, the automatic side of the flowchart is selected by the judgment command 35. At this time, the instruction 36 takes in the value of the blowout temperature detecting portion 9b, and the instruction 37 takes in the value of the blowing flow velocity detecting portion 9c. Next, instruction 38 sets the initial wind direction for analysis. As mentioned earlier, this value is
The angle θ _w during heating is set to 90 ° by measuring the angle downward with respect to the horizontal direction, and the angle θ _c during cooling is set in the horizontal direction.

The command 39 sets the initial value of the comfort index. This value is set to a relatively bad value. The comfort index is a physical representative value used for evaluating comfort, such as the average value of the temperature distribution in the living area, but when set in such a manner, the initial value is:
Set it to 0 ° C. Next, the comfort index range is set by the command 40. In the above example, this value is set to, for example, 15 ° to 25 ° C.

In the instruction 41, the hot air flow analysis is executed,
The analysis conditions at this time are defined as follows.

Area to be analyzed: It is given by the instruction 29. Air conditioner blow-in / suction position: Since the representative position of the air conditioner is given by the command 31, it is determined based on this value.

Initial condition of room temperature: given in command 33. Outlet Boundary Conditions: Instructions 36, 37, and 38 provide blowout temperature, flow velocity, and wind direction.

The analysis processor 22 is based on these values.
The hot air flow analysis is executed by the above, and the temperature and air flow distribution in the room are obtained.

Based on these values, the instruction 42 calculates the comfort index. This value is determined by the judgment command 43 as command 3
It is compared with the comfort index initial value set in 9. If the value of the comfort index has improved, then it is determined by the command 44 whether or not it is within the range of the required comfort index. If it is not within the required range, the command 45 changes the set value of the wind direction. That is, in this command 45, the step angle Δθ is appropriately set, the angle is set to θ _w −Δθ in the heating state, and the angle is set to θ _c + in the cooling state.
Let Δθ. This is to obtain the optimum value at an angle shallower than 90 ° in heating, and to obtain the optimum value at an angle deeper than 0 ° in cooling. When the wind direction is reset by the instruction 45, the analysis instruction 41 is executed again based on this value, and the same operation as that described above is performed. If the value of the comfort index is within the range set by the command 40 in this loop, the judgment command 44 is Yes.
Command 4 to select the s side and finally set the wind direction
The output signal processor 23 sends the signal to the wind direction motor drive circuit 26 as a drive signal output. As a result, the wind direction control louver 7 in the blowout portion 6 of the air conditioner 2 is driven. As a result, the comfortable state of the air-conditioned room 1 in the set state is set. In addition, the comfort index may not reach the required value even though the wind direction setting change command 45 is set. In this case, when the comfort index is not improved by the judgment command 43, the No option is selected, and the command 4 is issued to output the drive signal based on the wind direction immediately before it is not improved.
I send it by 6. The capacity control circuit 2
4 and the signal to the fan motor drive circuit 25 are
It is a separate system from the analysis processing, and is sent from the output signal processor 23 when the instruction 34 is executed.

If the instruction 35 does not select automatic, the instruction 46 outputs a drive signal based on the setting of the instruction 32.

After entering the above operating state, the judgment command 47 constantly checks whether or not there is a new input signal. At this time, the input signal processor 21 monitors as an input signal whether the room temperature (Tr) has changed by a predetermined value (Δt) or more and whether there is a new signal from the remote controller 3. How is it? If there is no new signal, the instruction 48 holds the idling state.

When a new signal is generated, the decision command 47 selects Yes and the decision command 49 checks whether it is the above-mentioned temperature signal. If it is a temperature signal, the judgment command 49 adopts the Yes option and returns to the room temperature detection command 33 again to follow the driving condition under this condition and the comfortable condition setting in the same manner as described above, and the wind direction. Set the conditions. If the input signal is not a temperature signal,
The judgment command 49 adopts the No option. Judgment command 50
Checks whether this signal is a stop command. If it is not a stop command, the option on the No side is adopted, and the process from command 32 onward is repeated. In the case of the stop command, the judgment command 50 adopts the option on the Yes side and the command 5
Due to 1, the operation of the air conditioner 2 is stopped.

According to the configuration of this embodiment, since the optimum air flow distribution based on the hot air flow analysis result is achieved, there is an effect that a comfortable air conditioning environment can be obtained.

[0032]

As described above, the air conditioning system of the present invention has the following effects. (1) A more comfortable air conditioning environment can be obtained because the optimum air flow distribution based on the hot air flow analysis result is achieved. (2) Since the wind direction is determined by constantly reflecting the results of hot air flow analysis in response to changes in room temperature, it is possible to realize a transitionally comfortable air conditioning environment.
