The work is completed when the vendor purchases the battery 17 and installs the third connector 15 and the power line 18 connecting this connector and the input end of the inverter 7 on the outdoor unit 1a.

して夫々作用することにより室内が冷房される。During the summer when there is a lot of solar radiation, the direct 1100V power generated by the solar cell 17 is transferred to the DC/D in the adapter 13.
C) After being converted into DC 280V (7) power by the inverter 16, it is input to the inverter 7 via the connection 18, converted to AC, and completely supplied to the compressor 2, and the DC 280V (7) power is
A part of the electric power of v is input to the controller 8 via the power line 19, and the output from the controller 8 is supplied to the inverter 7, the four-way valve 3, the refrigerant pressure reducer 5, the outdoor blower 9, and the indoor blower 11, respectively. The inverter 7 adjusts the operating frequency of the compressor 2 according to the temperature difference between the indoor temperature and the set temperature, and appropriately controls the valve opening of the refrigerant pressure reducer 5, which is an electric expansion valve. Therefore, the refrigerant discharged from the compressor 2 passes sequentially through the four-way valve 3, the outdoor heat exchanger 4, the refrigerant pressure reducer 5, the indoor heat exchanger 10, and the four-way valve 3, which are set to the solid state, and returns to the compressor 2. A cooling cycle is formed, and the indoor heat exchanger 4 acts as a condenser and the indoor heat exchanger 6 acts as an evaporator, thereby cooling the room.
又、日射量が少なく太陽電池１２の出力電圧が低い場合
には、その不足電力が商用電源１２で自動的にまかなわ
れる。即ち、太陽電池１７で発生する電力が充分大きい
時にはインバータ７の入力端が２８０賀以上あり商用電
源１２の出力２８０ｖ（１００ＶＸ２Ｘ、／Ｔ ）より
も高いため商用電源１２の電力が整流器６から出力され
ないが、日射量が少なくなって太陽電池１７の出力が下
がりインバータ７の入力端が２８０Ｖ以下になると商用
電源１２の出力２８０ｖとの差分だけ商用電源１２の電
力が整流器６から出力される。Further, when the amount of solar radiation is low and the output voltage of the solar cell 12 is low, the power shortage is automatically covered by the commercial power source 12. That is, when the power generated by the solar cell 17 is sufficiently large, the input terminal of the inverter 7 is at least 280V and is higher than the output of the commercial power supply 12 of 280V (100VX2X, /T), so the power of the commercial power supply 12 is not output from the rectifier 6. However, when the amount of solar radiation decreases and the output of the solar cell 17 decreases and the input terminal of the inverter 7 becomes 280V or less, the power of the commercial power supply 12 is output from the rectifier 6 by the difference from the output of the commercial power supply 12 of 280V.
従って、Ｄ Ｃ／Ｄ Ｃコンバータ１６から出力きれた
太陽電池１７の電力と整流器６から出力された商用電源
１２の電力とがインバータ７と制御器８に供給きれ、上
述と同様、冷房運転が行なわれて室内が冷房される。Therefore, the power of the solar cell 17 that has been output from the DC/DC converter 16 and the power of the commercial power source 12 that has been output from the rectifier 6 are fully supplied to the inverter 7 and controller 8, and the cooling operation is performed as described above. The room is cooled.
又、冬期においては、夏期に比べて日射量が少ないため
、太陽電池１７と商用電源１２との両室力がインバータ
７と制御器８に上述と同様に供給され、圧縮機２が駆動
きれると共に制御器８からの出力で四方弁３が破線状態

内送風機１１と冷媒減圧器５とが駆動される。従って、
圧縮機２から吐出された冷媒は四方弁３−室内熱交換器
１〇−冷媒減圧器５−室外熱交換器４−四方弁３を順次
経て圧縮機２に戻る暖房サイクルが形成きれ、室内熱交
換器１０が凝縮器として、室外熱交換器４が蒸発器とし
て夫々作用し、室内が暖房跡れる。In addition, in winter, since the amount of solar radiation is lower than in summer, the power from both the solar cells 17 and the commercial power source 12 is supplied to the inverter 7 and controller 8 in the same manner as described above, and the compressor 2 is driven completely. The four-way valve 3 is set to the broken line state by the output from the controller 8, and the outdoor blower 9, indoor blower 11, and refrigerant pressure reducer 5 are driven in the same way as during cooling operation. Therefore,
The refrigerant discharged from the compressor 2 passes through the four-way valve 3 - the indoor heat exchanger 10 - the refrigerant pressure reducer 5 - the outdoor heat exchanger 4 - the four-way valve 3 in order, and returns to the compressor 2 to complete the heating cycle, and the indoor heat is returned to the compressor 2. The exchanger 10 acts as a condenser, and the outdoor heat exchanger 4 acts as an evaporator, so that the room is heated.

い。In the above embodiment, the air conditioner 1 has been described as a separate air conditioner consisting of the outdoor unit 1a and the indoor unit 1b, but the air conditioner 1 has the indoor and outdoor units la and lb integrated. It may also be an integrated air conditioner.

既設の空気調和機をそのまま活用することができる。(G) Effects of the Invention According to the present invention, since an adapter is provided to supply electric power generated by a solar cell to an air conditioner, a customer can use an existing general air conditioner by purchasing the adapter and the solar cell. Because it can be operated using electricity from solar cells and commercial power sources,
Existing air conditioners can be used as is.

ームの普及に大いに貢献することができる。Also, when a customer purchases an air conditioner, if they cannot afford to purchase solar cells at the same time, they can first purchase only the air conditioner and run it on commercial power, and then when they have the time, they can install the solar cells and adapter. Since customers can buy more, it is easier for customers to buy, and it can greatly contribute to the spread of the energy saving boom using solar energy.
