Description

空気調和機Air conditioner
　本発明は、空気調和機に関する。 The present invention relates to an air conditioner.
　近年、従来よりも幅の狭いスペース（例えば、半間幅）に設置可能で、空気調和能力が従来よりも優れた空気調和機の開発が進められている。これらの要求を満たすためには、熱交換器及びファンのサイズを大きくしつつ、空気調和機全体のサイズを縮小させなければならない。例えば特許文献１には、熱交換器の下流側に設置されたクロスフローファンと、該クロスフローファンの端部にアウターロータ型モータを設けた空調室内機が開示されている。この空調室内機では、アウターロータ型モータを採用することによって、インナーロータ型モータで必要な軸心を設けるスペースを削減している。これにより、この空調室内機では、熱交換器及びファンのサイズを出来るだけ小さくすることなく、空気調和能力を維持しつつ、空調室内機全体のサイズを縮小させている。 In recent years, development of an air conditioner that can be installed in a narrower space (for example, a half-width) than the conventional one and has an air conditioning capability superior to the conventional one has been promoted. In order to satisfy these requirements, the size of the entire air conditioner must be reduced while increasing the size of the heat exchanger and the fan. For example, Patent Literature 1 discloses a crossflow fan installed on the downstream side of a heat exchanger and an air conditioning indoor unit in which an outer rotor type motor is provided at an end of the crossflow fan. In this air-conditioning indoor unit, by using an outer rotor type motor, a space for providing an axis necessary for the inner rotor type motor is reduced. Thereby, in this air conditioning indoor unit, the size of the entire air conditioning indoor unit is reduced while maintaining the air conditioning capability without reducing the size of the heat exchanger and the fan as much as possible.

The indoor unit 2 is provided with a cross flow fan 21 and an indoor fan motor unit 22. The cross flow fan 21 sucks indoor air and supplies the air heat-exchanged by the indoor heat exchanger 20 into the room. The indoor fan motor unit 22 rotates the cross flow fan 21.
　アキュムレータ３１、圧縮機３２、四路切換弁３３、室外熱交換器３０および電動膨張弁３４は、室外機３内に配置されている。アキュムレータ３１は、圧縮機３２の吸入側に接続され、四路切換弁３３は、圧縮機３２の吐出側に接続されている。 The accumulator 31, the compressor 32, the four-way switching valve 33, the outdoor heat exchanger 30, and the electric expansion valve 34 are disposed in the outdoor unit 3. The accumulator 31 is connected to the suction side of the compressor 32, and the four-way switching valve 33 is connected to the discharge side of the compressor 32.
　また、室外機３には、プロペラファン３８と室外ファンモータユニット３９とが設けられている。プロペラファン３８は、室外熱交換器３０で熱交換された空気を外部に排出する。室外ファンモータユニット３９は、プロペラファン３８を回転させる。 Further, the outdoor unit 3 is provided with a propeller fan 38 and an outdoor fan motor unit 39. The propeller fan 38 discharges the air heat-exchanged by the outdoor heat exchanger 30 to the outside. The outdoor fan motor unit 39 rotates the propeller fan 38.
　上記構成の空気調和システム１において、暖房運転時には、四路切換弁３３を実線に係る位置に切り換える。これにより、圧縮機３２から吐出された高温高圧冷媒が四路切換弁３３を通って室内熱交換器２０に流入する。室内熱交換器（凝縮機）２０で凝縮した冷媒は、電動膨張弁３４で減圧された後、室外熱交換器３０に流入する。そして、室外熱交換器（蒸発器）３０で蒸発した冷媒が、四路切換弁３３及びアキュムレータ３１を介して、圧縮機３２の吸入側に戻る。このようにして、室内熱交換器２０の周囲の空気が加熱され、この加熱された空気がクロスフローファン２１よって室内に送られて、室内に温風が供給される。 In the air conditioning system 1 configured as described above, during the heating operation, the four-way switching valve 33 is switched to the position related to the solid line. As a result, the high-temperature and high-pressure refrigerant discharged from the compressor 32 flows into the indoor heat exchanger 20 through the four-way switching valve 33. The refrigerant condensed in the indoor heat exchanger (condenser) 20 is decompressed by the electric expansion valve 34 and then flows into the outdoor heat exchanger 30. Then, the refrigerant evaporated in the outdoor heat exchanger (evaporator) 30 returns to the suction side of the compressor 32 via the four-way switching valve 33 and the accumulator 31. In this way, the air around the indoor heat exchanger 20 is heated, and the heated air is sent into the room by the crossflow fan 21 to supply hot air into the room.
　また、冷房運転時には、四路切換弁３３を点線に係る位置に切り換える。すると、圧縮機３２から吐出された高温高圧冷媒が四路切換弁３３を通って室外熱交換器３０に流入する。室外熱交換器（凝縮器）３０で凝縮した冷媒は、電動膨張弁３４で減圧された後、室内熱交換器２０に流入する。そして、室内熱交換器（蒸発器）２０で蒸発した冷媒が、四路切換弁３３及びアキュムレータ３１を介して、圧縮機３２の吸入側に戻る。このようにして、室内熱交換器２０の周囲の空気が冷却され、この冷却された空気がクロスフローファン２１によって室内に送られて、室内に冷風が供給される。 Also, during the cooling operation, the four-way selector valve 33 is switched to the position indicated by the dotted line. Then, the high-temperature and high-pressure refrigerant discharged from the compressor 32 flows into the outdoor heat exchanger 30 through the four-way switching valve 33. The refrigerant condensed in the outdoor heat exchanger (condenser) 30 is decompressed by the electric expansion valve 34 and then flows into the indoor heat exchanger 20. Then, the refrigerant evaporated in the indoor heat exchanger (evaporator) 20 returns to the suction side of the compressor 32 via the four-way switching valve 33 and the accumulator 31. In this manner, the air around the indoor heat exchanger 20 is cooled, and the cooled air is sent into the room by the crossflow fan 21 and cold air is supplied into the room.
