Abstract:
A package-type compressor 2 is provided with, in a package 4: a compression unit 6a; a compressor motor 6c that drives the compression unit 6a; a first inverter 24 that drives the compressor motor 6c; a first control circuit 28 that controls the first inverter 24; a first battery 10 that supplies power to the first inverter 24 and the first control circuit 28; and a step-down transformer 26 that reduces a voltage supplied from the first battery 10 to the first circuit control 28. The first battery 10 is supplied with system power 20 from outside the package 4. Thus, it is possible to provide a compressor 2 that can operate continuously while maintaining a non-power-outage state, even when an instantaneous power outage or a normal power outage occurs.
