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 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.

It is displayed on 20b and 20c. This value is processed by the obstacle size input command 34b.

Next, the target room temperature, the air volume, and the wind direction are input by the setting units 17, 18, and 19 of the remote controller 3, respectively. This is processed by the instruction 35, 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 instruction 36. In the instruction 37, the target room temperature set in the instruction 35 and the room temperature taken in in the instruction 36 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 38. At this time, the value of the blowout temperature detection unit 9b is fetched by the command 39, and the value of the blowout flow velocity detection unit 9c is fetched by the command 40. Next, command 41 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 42 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 43. In the above example, this value is set to, for example, 15 ° to 25 ° C.

In instruction 44, a 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.

Obstacle position and size: Since the representative position and size of the obstacle 4 are given in the commands 33 and 34b, the obstacle position and size are determined based on these values.

Initial conditions for room temperature: given in command 36. Blowout port boundary condition: blowout temperature, flow velocity, and wind direction are given by instructions 39, 40, and 41. The hot air flow analysis is executed by the analysis processor 22 based on these values, and when the obstacle 4 exists. The room temperature and air flow distribution are calculated.

The comfort index is calculated by the instruction 45 based on these values. This value can be
It is compared with the comfort index initial value set in 2. If the value of the comfort index has improved, then it is determined by the command 47 whether or not it is within the range of the required comfort index. If it is not within the required range, the command 48 changes the set value of the wind direction. That is, in this command 48, 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 command 48, the analysis command 44 is executed again based on this value, and the same operation as that described above is performed. If the comfort index value is within the range set by the command 43 in this loop, the judgment command 47 returns 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 with the obstacle 4 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 48 is set. In this case, the judgment command 46
Therefore, when the comfort index is not improved, the No option is selected, and the drive signal output is sent by the command 49 based on the wind direction immediately before the improvement is not achieved. The signals to the capacity control circuit 24 and the fan motor drive circuit 25 are sent from the output signal processor 23 when the instruction 37 is executed, in a system different from the analysis processing.

When the automatic mode is not selected in the command 38, the drive signal output is issued by the command 49 based on the setting of the command 35.

After entering the operating state as described above, the decision command 50 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 51 holds the idling state.

When a new signal is generated, the decision command 50 selects Yes and the decision command 52 checks whether it is the above-mentioned temperature signal. If it is a temperature signal, the judgment command 52 adopts the option on the side of Yes, returns to the room temperature detection command 36 again, and follows the driving condition and comfort condition setting under this condition as in the case described above, and wind direction. Set the conditions. If the input signal is not a temperature signal,
The judgment instruction 52 adopts the No option. Judgment command 53
Checks whether this signal is a stop command. If it is not the stop instruction, the option on the No side is adopted, and the process from the instruction 35 onward is repeated. In the case of the stop command, the judgment command 53 adopts the option on the side of Yes and the command 5
4, the operation of the air conditioner 2 is stopped.

According to the configuration of this embodiment, the optimum air flow distribution based on the hot air flow analysis result in the presence of the obstacle 4 is achieved, so that a comfortable air conditioning environment can be obtained.

[0034]

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 heat air flow analysis result considering the existence of obstacles 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.
