Solar cells are attracting attention as a clean energy source. However, fluctuations in the amount of power generation due to changes in the amount of solar radiation (100 in fine weather, less than 10 in rainy weather), incident angle of sunlight on the solar cells As a result, fluctuations in the amount of power generation due to changes in power generation become a bottleneck, and there are still many points that are insufficient as a practical energy source. For this reason, the spread of air conditioners using solar power generation has been hindered.

As shown in FIG. 5, a solar cell 2 is provided in parallel with the commercial power supply 1 as a drive source of the air conditioner, and a direct current obtained by rectifying an alternating current from the commercial power supply 1 or power of the solar cell 2 is obtained. The control unit 3 is connected to the control unit 3 via a switching unit SW that switches to use one of them or to use both of them. The control unit 3 determines a ratio of using the electric power of the commercial power supply 1 and the power of the solar cell 2 by operating a remote controller 6 (hereinafter, referred to as a “remote controller”), and controls the indoor unit 4 and the outdoor unit 5 through the switching circuit 10.

Operate the air conditioner only.
Conversely, when the amount of solar radiation is relatively small and the output of the solar cell 2 is insufficient, the air conditioner is operated using the commercial power supply 1 and the solar cell 2 together or the commercial power supply 1 alone.

太陽電池２が必要となる。However, even in a clear and sunny condition with a large amount of solar radiation, it is necessary to supply all the necessary power from the start-up to the control of the entire air conditioner system using only the power supplied from the solar cell 2. Requires a very large capacity solar cell 2. For example, to cool and heat a room of about 12 m 2 (about 8 tatami mats), a solar cell 2 having a capacity of about 2 kW is required. In this case, a solar cell 2 having an effective area of about 20 m 2 or more is required.

問題もあった。Accordingly, the size per unit module and the total number of modules of the solar cell 2 constituted by arranging a plurality of modules without gaps are increased, and therefore, the solar cell 2 including an angle for installing the solar cell 2 is included. The photovoltaic power generation system itself becomes large and the weight becomes considerably heavy (about 300
kg). In addition, devices for power conversion by solar power generation, power supply and control, etc. become complicated and large-scale,
There was also a problem that a great deal of labor and cost were required for these installation works.

On the other hand, even in a single-family house, depending on the angle of the roof, the solar cell 2 cannot be installed at an appropriate position with respect to the solar radiation direction, or the roof must have sufficient strength to support the weight of the solar power generation system. There was a problem in terms of housing circumstances, such as the situation.

As shown in the figure, inside the indoor unit 4, a control unit 3 for controlling the operation of the air conditioner is provided, and the human body sensor 7 and the temperature sensors 8, 9 are connected to the input side thereof. Is connected to a switching circuit 10, a drive circuit 11 for the indoor unit 4, and a drive circuit 12 for the outdoor unit 5.

等が行える。A commercial power supply 1 and a solar cell 2 are connected in parallel to the switching circuit 10 via a switching unit SW. The switching circuit 10 switches to one of them based on a command from the control unit 3. The contact of the section SW is switched. By operating the remote controller 6 in this configuration, selection of the operation mode of the air conditioner, setting of the room temperature or the timer, and the like can be performed.

で、暖房運転については説明を省略する。A first embodiment of the present invention will be described. Hereinafter, the case of the cooling operation will be described as an example. However, since the configuration and operation of the air conditioner can be applied to the case of the heating operation, the description of the heating operation will be omitted.

代が掛かり不経済であった。Conventionally, when leaving home due to work or the like, it was necessary to estimate the time to return home, set an entrance timer earlier than that time, and then go out.
However, in the closed indoor environment in summer, the temperature rise is remarkable, and especially in recent highly airtight and highly insulated houses, the heat retention is extremely high, so much electric power is needed to cool the room once the temperature has risen. is necessary. Therefore, the cooling operation from the set time of the on-timer to the return to the home causes an extra cost for electricity, which is uneconomical.

くて済むので、ランニングコストを大幅に削減できる。Therefore, in the present embodiment, the user can operate the remote controller 6 to switch to the operation mode using the solar cell 2 when going out. In particular, since the amount of solar radiation is extremely large in the summer, even if the solar cell 2 has a low capacity, an appropriate cooling effect can be obtained by maintaining the operation of the air conditioner by the solar power generation. Abnormal temperature rise can be suppressed. As a result, the discomfort caused by the heat trapped in the room felt when returning home is eliminated. Moreover, after returning home, it is sufficient to switch to the commercial power supply 1 and start the cooling operation,
Compared with the conventional case where cooling is performed from a state in which the room temperature is increased, the power required at the time of starting operation with the commercial power supply 1 can be reduced, so that the running cost can be significantly reduced.

With a conventional air conditioner that does not use solar power generation, as shown by the dotted line in the figure, after going to work around 8:00 am, the room temperature starts to rise sharply, and reaches a peak around 3:00 pm . Thereafter, the timer set at 5:00 pm is turned on, the commercial power supply 1 is turned on, the cooling operation is started, and the room temperature is comfortable when returning home (7:00 pm).

Therefore, even if the user returns home at 7:00 pm and switches to the commercial power supply 1 to start cooling, the operation is started from a state in which the room temperature is relatively low, so that the load on the air conditioner is significantly reduced. , It is possible to save energy.

The air conditioner is controlled by the control unit 3 so that all of the power according to In this case, the power obtained by the solar power generation depends on the weather condition, that is, the amount of solar radiation, but the operation is performed within a range of power corresponding to the amount of power generated by the solar cell 2. That is, when the power from the solar power generation exceeds the minimum value required for the operation of the air conditioner, the operation is compulsorily performed, and when the electric power is less than the predetermined value, the operation is compulsorily stopped.

A human body sensor 7 for detecting and reacting to a human body is provided on an exterior portion of the front of the indoor unit 4 of the air conditioner. Then, as shown in FIG. 2, using the output of the sensor 7, when no person is present in the room for a predetermined time or more, the control unit 3 switches the switching unit SW to the solar cell 2 side to switch to the solar power generation mode. Cooling operation is continued. According to this, even if the user leaves the room for a while or forgets to switch to the solar power generation mode when going out, wasteful power consumption can be prevented. Since the discomfort due to is eliminated, the comfort of the living space is improved.

Using the output of the above, the air temperature is set to a predetermined reference value (for example, 26 ° C.).
When the room temperature is higher than the reference value and the operation of the air conditioner is stopped, after the commercial power supply 1 is supplied to the control unit 3, the operation is started in the solar power generation mode and the cooling operation is started. You can also do so. It is needless to say that the heating operation in the photovoltaic power generation mode can be similarly performed by the control of the reverse pattern. However, the reference value in this case shall be set lower than in the case of the cooling operation described above according to the Ordinance of the Ministry of International Trade and Industry.

Some recent air conditioners have a function of increasing added value and have dehumidification, humidification, and ventilation (air purification) functions. In the present embodiment, the power related to these functions is supplied to the solar cell 2. I am trying to cover it. That is, as shown in FIG. 4, when the cooling (heating) mode is selected by operating the remote controller 6, the control unit 3 supplies electricity to the drive circuits 11 and 12 using the commercial power supply 1 to operate the refrigeration cycle (solid line). With the arrow (arrow), the dehumidification / humidification and air cleaning circuit 13 is driven by using the power from the solar cell to perform the dehumidification and the like, which are functions independent of the refrigeration cycle, using the solar cell 2 (dotted arrow). )

Since it is impossible to flow a current exceeding 20 A due to capacity regulation, the current for driving the refrigeration cycle of the air conditioner is reduced, and the current for the function of dehumidification and the like is reduced by about 2%.
It is limited to 0A. In other words, at the expense of air conditioning capacity,
That amount is assigned to the additional function such as the dehumidification.

Therefore, without lowering the air conditioning capacity,
