Abstract
A compressor unit includes a compressor and an accumulator. The compressor includes a vertically elongated first casing, an electric motor, a drive shaft, and a compression mechanism. The accumulator includes a vertically elongated second casing. In a frequency range between a value three times larger than a maximum compressor rotation speed and 1.25 times greater than the value when a first part is vibrated, an index showing a frequency response function of the second casing in a circumferential direction in a second part is 1.0 m/s/N or less. The first part is part of an upper part of a side surface of the first casing and is orthogonal to an alignment direction of the compressor and the accumulator, and the second part is part of an upper part of a side surface of the second casing and is opposed to a part facing the first casing.
