設定されている。By the way, the fuzzy calculation is executed at predetermined intervals (t seconds) during the operation of the air conditioner, and the switching amount of the operating frequency of the compressor 2 is controlled based on the result of the fuzzy calculation. The predetermined interval (t seconds) is set to an optimum value based on the result of testing in advance according to the actual use condition of the air conditioner. For example, the predetermined interval is set so that it is neither too long nor too short.

This is because it becomes significantly worse, which in turn impairs comfort. Further, as shown in FIG. 8, when the predetermined interval is a short value t2 (<t), the room temperature (T
The switching of the operating frequency of the compressor 2 is sensitive to the fluctuation of r) and the stability of the room temperature is good, but the switching of the operating frequency is performed very frequently, and therefore, when the operation is continued for a long time, the air This is because the power consumption of the harmony machine is large, and the operating efficiency is deteriorated.

損なわれることになる。However, in the control method of the air conditioner, the operating frequency of the compressor 2 can be switched only every t seconds, that is, the interval is a halfway interval. When the load is large, the change of the operating frequency of the compressor 2 becomes sharp and the switching of the operating frequency of the compressor 2 becomes violent. become.

Alternatively, when controlling the temperature in the same room by blowing hot air, the temperature difference between the detected room temperature and the set temperature is input 1, the change amount of the room temperature is input 2, and based on these inputs 1 and 2, Is a control method of an air conditioner, in which a fuzzy calculation is performed using a preset control rule and a membership function, and the switching amount of the operating frequency of the compressor is controlled at regular time intervals based on the fuzzy calculation result. , Calculating the number of switching of the operating frequency of the compressor for each predetermined time,
The gist is that the fixed time for controlling the switching amount of the operating frequency is changed according to the number of times of calculation.

が行われる。Since the above method is used, the number of times the operating frequency of the compressor is switched every predetermined time (A) during operation of the air conditioner, that is, the number of times counted once each time the operating frequency is switched is calculated. When the calculated rotation speed is equal to or lower than the predetermined value (n), it is determined that the fluctuation of the room temperature is small, or the fluctuation of the room temperature is large, and the operation frequency switching amount (the fluctuation of the operating frequency) is small. In this case, the fixed time for controlling the switching of the operating frequency of the compressor is shortened, and the room temperature control is performed with emphasis on the room temperature stability.

Is judged to be large.
In this case, since the fixed time for controlling the switching of the operating frequency of the compressor is lengthened, the stability at room temperature is slightly deteriorated, but the energy saving operation (operating efficiency) with little fluctuation of the operating frequency is emphasized. Room temperature control is performed.

When the air conditioning load is small, it is possible to perform room temperature control with an emphasis on operating efficiency, and it becomes possible to perform optimum operation according to the state of the air conditioning load.

First, the operation of the air conditioner, for example, the set temperature and the room temperature by the remote controller are controlled. It is assumed that the indoor fan, the outdoor fan, the compressor 2 and the like are controlled based on this.

Through the membership function shown in FIG. 6, a fuzzy operation is executed according to the control rule shown in the above equation 1, and the room temperature is controlled based on the result of the fuzzy operation. At this time, the fuzzy calculation is performed for a certain time (t3
The operation frequency is switched at every interval (second), the switching amount of the operating frequency of the compressor 2 is controlled based on the calculation result, and the operating frequency is switched. The constant time (t3) is shorter than the constant time (t seconds) described in the conventional example, for example.

される。As shown in FIG. 2, when the operating frequency of the compressor 2 is switched at regular intervals (t3), the compressor operating frequency switching frequency calculation section 4 switches the operating frequency. The counter is operated every time the number of times of switching is calculated, and the operation of this counter is performed for a predetermined time (A). Incidentally. When the switching amount of the operating frequency does not change, the operating frequency is not switched and the counter is not operated. Further, this counter is reset and started after a predetermined time (A) has elapsed.

なる。Here, the count number of the counter, that is, the switching frequency of the operating frequency is calculated at the time when the predetermined time (A) has elapsed, and whether the calculation frequency exceeds the predetermined value (n). To be judged. When the number of times the operating frequency is switched is large and the calculated number of revolutions exceeds a predetermined value (n) despite a small change in room temperature (that is, despite a small air conditioning load) (Fig. 2)), a fixed time for controlling the switching amount of the compressor 2 is set to a longer fixed time (t4 seconds). As a result, the switching timing of the operating frequency becomes long, that is, the switching interval becomes long, so that the fluctuation of the room temperature becomes a little larger and the stability of the room temperature becomes a little worse. However, since the number of times the operating frequency is switched during the predetermined time (A) is extremely reduced, the power consumption of the air conditioner can be reduced, the operating efficiency is improved, and the energy saving operation is performed.

とになる。Even during the predetermined time (A), the compressor operating frequency switching frequency calculating section 4 calculates the operating frequency switching frequency in the same manner as described above. Due to the decrease in the number of times of switching, for example, even when the change in the room temperature is large, or even when the air conditioning load is large, after a lapse of A minutes, the number of times the operating frequency is switched is a predetermined value ( When it is less than n), the fixed time for controlling the switching amount of the compressor 2 is set to a short fixed time (t3). As a result, the number of times the operating frequency is switched is increased, so that the stability at room temperature is improved and comfort is achieved.

性が良好にされる。As described above, in the fuzzy control for controlling the switching amount of the operating frequency of the compressor 2, the number of times the operating frequency is switched is calculated every predetermined time (A), and the number of calculations is a predetermined value (n). ) Is exceeded,
It is determined whether or not it is less than that, and when the number of calculations exceeds a predetermined value (n), the fixed time for controlling the switching amount of the operating frequency is changed to a longer value (t4), and the number of calculations is When the value becomes equal to or less than the predetermined value (n), the fixed time for controlling the switching amount of the operating frequency is changed to a shorter value (t3). Therefore, even if the change in the room temperature is small, when the number of times the operating frequency is switched is large, the number of times that the operating frequency is switched is small, which improves the operating efficiency.
Despite the energy-saving operation being performed and the fluctuation of the room temperature being large, when the number of times the operating frequency is switched is small, the number of times the switching is performed is large, so that the stability of the room temperature is improved.

The amount of switching of the operating frequency of the output compressor is calculated, and the operating frequency is switched at regular time intervals to control the room temperature. However, the number of times the operating frequency is switched is calculated every predetermined time (A). The constant time for controlling the switching amount of the operating frequency is varied according to the number of times of calculation, and when the number of times of calculation exceeds a predetermined value (n), the certain time is set longer and the number of times of calculation is a predetermined value. When the value is (n) or less, the certain period of time is set to be short, so that it is possible to perform room temperature control that emphasizes room temperature stability (comfort) by changing the operating frequency during room temperature control.
