That is, themotor rotating shaft 330, which is the rotating shaft of themotor 303, is located below the gas-enginerotating shaft 340, which is the rotating shaft of thegas engine 301, in the height direction. Themotor rotating shaft 330, which is also the rotating shaft of thecompressor 102, is located below the gas-enginerotating shaft 340, which is the rotating shaft of thegas engine 301. - The
first heat exchanger 106 is provided in theheat exchanger room 160 so as to cover the side surfaces of thefirst heat exchanger 106. Twooutdoor fans 107 are provided at theheat exchanger room 160. - By operating the

Thegas engine 301 in operation becomes very hot and generates radiant heat (exhaust heat) around thegas engine 301. The ambient temperature of thegas engine 301 increases. However, since theoutdoor fans 107 cause theair passage 305 to be provided from themachine room 150 to theheat exchanger room 160, the exhaust heat of thegas engine 301 is exhausted to a location above thegas engine 301. As a result, temperature rise at a location where thecompressor 102 and themotor 303 are installed, that is, a location below thegas engine 301 is suppressed. - As described above, in the present embodiment, by installing the

Since thegas engine 301 is indirectly linked to thecompressor 102 via the transmitting means 302, the transmission of the vibration of thegas engine 301 to thecompressor 102 and themotor 303 is suppressed. - As described above, in the present embodiment, by linking the
gas engine 301 to thecompressor 102 and themotor 303 via the transmitting means 302, it is possible to prevent the vibration of thegas engine 301 from being directly transmitted to thecompressor 102 and themotor 303. As a result, it is possible to prevent shaft misalignment failures caused by vibration between thecompressor 102 and themotor 303, and, thus, improve operation reliability of theair conditioner 100. - In the present embodiment, the structure in which the
compressor 102 and themotor 303 are coaxially linked to each other is described. When thecompressor 102 and themotor 303 are linked to each other via similar transmitting means differing from the transmitting means 302, or when themotor 303 exists in thecompressor 102, it is also possible to similarly provide the same effects by similarly installing thecompressor 102 and themotor 303 below therotating shaft 340 of thegas engine 301. - Although, in the present embodiment, an air conditioner device including one indoor unit or two or more indoor units is described, an air conditioner device including a plurality of indoor units may be used.
- As described above, the outdoor unit for the air conditioner according to the present disclosure is suitably used as an air conditioner device that, by suppressing temperature rise of the motor, prevents failures caused by demagnetization of the motor and, thus, improves operation reliability of the air conditioner.
Claims (4)
