する。 Here, the control device 12 converts an alternating current voltage applied via the power switch 10 and the power transformer 11 into a direct current voltage, and uses this direct current voltage as a control voltage to drive the internal circuit. The internal circuit is composed of a microprocessor, etc., and inputs the set temperature signal set by the indoor temperature setting device (not shown) and the detected temperature signal detected by the indoor temperature detector 13, and calculates the difference between the two. The indoor fan 14 whose rotation speed is variable in multiple steps is controlled to the optimum rotation speed. On the other hand, the set temperature signal and the detected temperature signal are applied to the control device 20 of the outdoor unit 2 via the terminal plates 26 and 27. Then, the control device 20 calculates the optimum rotation speed of the compressor 25 based on the difference signal and provides a frequency setting signal to the inverter 24. Since the main circuit of the inverter 24 is supplied with DC power rectified by the rectifier circuit 23, the inverter 24
4 is turned on and off by the frequency setting signal to drive the compressor 25 at a frequency corresponding to the air conditioning load.

お、冷房運転も同様な制御が行なわれる。 Figures 2A, 2B, and 2C are diagrams for explaining the conventional air volume control method of the indoor fan 14 during heating, and Figure 2A shows the control state of the indoor temperature T A ;
Figure 3 shows the compressor capacity, and Figure 2 shows the air volume of the indoor fan. On the vertical axis of Figure 2 A, the difference between the set temperature T S and the room temperature T A is expressed as A, B,
Divide into three zones: C. That is, during heating operation, the range where the indoor temperature T A is lower than the set temperature T S by, for example, 2.5°C or less is defined as the A zone, the range 1.0 to 2.5°C lower is defined as the B zone, and the range 0 to 1.0°C lower is defined as the C zone. Then, at t 1 when heating operation starts,
When the indoor temperature T A is in zone A, the compressor capacity is set to "high" and the compressor 25 is rotated at high speed, and at the same time, the indoor fan 14 is also set to "strong wind" and rotated at high speed, thereby reducing the indoor temperature. Raise T A rapidly. As the indoor temperature T A rises and approaches the set temperature T S , that is, B
When in zone C, the compressor capacity is set to "medium" and the indoor fan 14 is also set to "light wind"; when in zone C, the compressor capacity is set to "small" and the indoor fan 14 is also set to "light wind".
state. When the indoor temperature T A reaches the set temperature T S , the compressor 25 is stopped, and the indoor fan 14 is stopped or rotated at an extremely low speed. 25 is restarted and the indoor temperature T A is controlled to be equal to the set temperature T S . In this way, the indoor fan 14 is sequentially changed from a light breeze to a strong wind and from a strong wind to a light breeze in response to changes in the indoor temperature T A to provide comfort. Note that similar control is performed for cooling operation.

However, in the conventional air volume control method, especially when the heating load is large, the compressor 2
5, the indoor temperature T A may suddenly drop to the A zone, but in such a case, the restart is performed from the A zone at time t 2 or t 3 , and the indoor temperature returns to normal within a short period of time, for example, within a few minutes. Because fan 14 changes from "strong wind" to "weak wind" to "light wind",
The disadvantage was that the unevenness of wind speed and the difference in blowing noise became large, resulting in poor comfort.

ても同様に応用することができる。 First, the features of the present invention will be explained with reference to FIG. 2. In the present invention, as shown by the hatched area in FIG . → Operate with a “light breeze” and lower air volume than before. This will alleviate the change in air volume caused by a rise in room temperature, and reduce uneven air volume and fluctuations in ventilation noise. Here, there is a concern that if such air volume control is performed, the heating capacity during the temperature control state (so-called thermo control state) to maintain the indoor temperature T A at the set temperature T S may be insufficient. This is at the time of start-up (i.e. starting) t 1
This is because the indoor temperature is not low and the indoor wall temperature is not low, but the indoor temperature T A has increased and there is no temperature unevenness at the time of restart t 2 or t 3 . There is sufficient heat stored in furniture, interior walls, etc., and the lack of heating capacity is compensated for by this stored heat, so the above-mentioned problems do not occur.
Further, the air volume control as described above can be similarly applied during cooling operation.

順次急速に変化させて室内温度TAを早く設置温
度TSに到達させる。 On the vertical axis in Figure 3A, the difference between the set temperature T S and the indoor temperature T A is divided into seven zones (first zone). In other words, during heating operation, if the slope is rising, the set temperature T S is 0.5°C lower than the indoor temperature T A.
A high range of 0.5 to 1.0 degrees Celsius is a "breeze + " zone, a range of 1.0 to 1.5 degrees Celsius is a "weak wind - " zone, a range of 1.5 to 2.0 degrees Celsius is a "weak wind" zone.
zone, 2.0 to 2.5℃ higher zone as "weak wind + " zone,
2.5 to 3.0℃ higher range is classified as “strong wind- ” zone, and 3
The range up to 3.5 degrees Celsius is defined as the "strong wind" zone. In the case of a downward slope (right side from the center of Figure 2)
lowers the seven zones by 0.5°C. This is done by setting a 0.5℃ difference between the upward slope zone setting and the downward slope zone setting, and uses this difference as hysteresis to control the indoor temperature.
This is to prevent frequent switching of the air volume after T A reaches the target value. In this way, the air volume zone during heating operation is divided into seven zones, and when starting operation when the indoor temperature T A is low, the indoor fan 14 is sequentially rapidly changed from the "strong wind" zone to the "light wind" zone to maintain the indoor temperature T A quickly reaches the installation temperature T S.

る。 Then, when the indoor temperature T A reaches the set temperature T S and the compressor 25 stops, the air volume control is thereafter performed as shown in FIG. 3B. In Figure 3B, the 3rd
Since each zone in Figure A is configured as an air volume zone (second zone) that is lowered by 1 degree Celsius, for example, the air volume from the indoor fan 14 changes from "strong wind" to "weak wind" to "light wind" at the time of restart. The timing of the change to `` is earlier than in Figure 3 A. In other words, when the indoor temperature T A is slightly lower than the set temperature T S ,
The indoor fan 14 is restarted from the low zone from the "strong wind" state to the "weak wind" state, or from the "weak wind" state to the "high wind" state. Therefore, even if the indoor temperature T A suddenly drops after the compressor 25 stops due to a large heating load, the indoor fan 14
Since the fan starts rotating from one step lower zone, the air volume does not change frequently in response to fluctuations in the indoor temperature T A , which can reduce uneven air volume and fluctuations in ventilation noise.

房時とほぼ同様の作用、効果を奏する。 During cooling operation, the air volume zone at the time of start-up is divided into seven zones (first zone group) that are oriented upside down compared to Figure 3 A, as shown in Figure 4 A, and the As shown in Figure 3B, the air volume zone at the time of restart is divided into seven zones (second zone group) that are oriented upside down compared to Figure 3B, and the rotation speed of the indoor fan 14 is sequentially changed according to each division. If you do so, you will get almost the same action and effect as when heating.

減できる。 FIG. 5 shows an example for implementing the above air volume control method, in which the indoor temperature sensor 1, which is a resistor,
The following components are connected between the controller 3 and a microprocessor (not shown) in the controller 12. That is, a relay contact 30 used during cooling is provided between one end of the room temperature detector 13 and the microprocessor.
The normally closed terminal of the relay contact 31 and the normally closed terminal of the relay contact 31 used for heating are connected in series, and the normally open terminal of the relay contact 30 is connected to the indoor temperature detector 13 via the cooling resistor 32. A heating resistor 3 is connected to the normally open terminal of , and the other end of the indoor temperature sensor 13
3 is connected. When the heating starts, the indoor temperature detector 13 is connected to the microprocessor via the normally closed terminals of the relay contacts 30 and 31, so the microprocessor directly detects the change in the resistance value of the indoor temperature detector 13. Then, the air volume control shown in FIG. 3A is performed. When the indoor temperature T A reaches the set temperature T S and the compressor 25 stops, the heating relay contact 31 is switched from the normally closed terminal to the normally open terminal by a control signal from the microprocessor, and the heating resistor 33 is switched from the normally closed terminal to the normally open terminal. It is connected in parallel to the indoor temperature detector 13. Then, the combined resistance of the room temperature detector 13 and the heating resistor 33 becomes smaller, so that the microprocessor detects a temperature higher than the actual room temperature TA . By appropriately selecting the resistance value of the heating resistor 33, for example, if the set temperature T S is 25 degrees Celsius and the actual room temperature T A is 22 degrees Celsius, then in the case of Figure 3 A, the "strong wind" zone will be reached. However,
Since the heating resistor 33 is inserted in parallel, the microprocessor determines that the indoor temperature is 24° C. and gives a command to the indoor fan 14 to rotate in the "low wind " zone.
For this reason, restart operation will be performed in the form shown in FIG. 3B. In addition, when the indoor temperature T A reaches the set temperature T S during cooling operation and the compressor 25 stops, the cooling relay contact 30 is switched from a normally closed terminal to a normally open terminal by a control signal from the microprocessor. A resistor 32 is connected in series to the indoor temperature detector 13. Then, the indoor temperature read by the microprocessor becomes lower than the actual indoor temperature T A , and restart operation is performed as shown in Figure 4 (b). Therefore, during thermo-control etc., when the air conditioner is actually used, changes in air volume can be reduced, improving comfort. Furthermore, since changes in air blowing noise due to extreme changes in air volume are suppressed, the user does not need to be aware of the air conditioner. Furthermore, since extreme differences in wind speed do not occur, room temperature distribution and perceived temperature differences can be reduced.

You can do it like this. In actual use, it is particularly effective when heating. In addition, as a method to lower or increase the air volume zone at the time of restart, use the resistor 3 as shown in Figure 5 above.
2 and 33, for example, a microprocessor installed in the control device 12 may be used to change the set value of the air volume zone.

As described above, in the present invention, after the indoor temperature reaches the set temperature, the indoor fan is driven using another zone group shifted to the side where the difference between the indoor temperature and the set temperature is large. Therefore, when the air conditioning load is large, the amount of change in air volume that changes as the indoor temperature approaches the set temperature when restarting is greatly reduced, reducing uneven air volume and fluctuations in fan noise, making it more comfortable. performance is significantly improved.
Further, according to the present invention, after the indoor temperature reaches the set temperature, the indoor fan is driven using a zone group in which the rotation speed corresponding to the zone is simply shifted to the side where the temperature difference is large. Even if the temperature difference increases due to a sudden change in load, it is possible to operate at the maximum rotation speed, and it also has a so-called speed control function.
