Compressor unit and refrigeration apparatus

A compressor unit for use in a refrigeration apparatus configured to perform a refrigeration cycle, the compressor unit comprising:

• a compressor body including a compression mechanism;
• and
• an accumulator connected to the compressor body,
• the compression mechanism including
• a cylinder,
• a piston configured to rotate eccentrically in the cylinder, and
• a blade partitioning an interior of a compression chamber of the cylinder into a low-pressure chamber and a high-pressure chamber, and

• F represents a value obtained by multiplying a weight of the piston and the blade by a square of a number of revolutions of a motor of the compressor body,
• h represents a distance from a center of the piston in a thickness direction to a center of gravity of the compressor unit,
• I represents a moment of inertia around a center axis of the compressor unit passing through the center of gravity of the compressor unit, which is also a center of rotation of the compressor body during vibrations in a direction in which the compressor body inclines toward the accumulator,
• L represents a distance from an axis of an inlet pipe of the accumulator to the center of gravity of the compressor unit,
• V represents a volume of the cylinder, and
• N represents the number of revolutions of the motor of the compressor body, which is greater than or equal to a predetermined number of revolutions, the predetermined number of revolutions of the compressor body being greater than or equal to 112 rps.
