Title:
COMPRESSOR UNIT AND REFRIGERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/053672
Kind Code:
A1
Abstract:
In the present invention, a value F obtained by multiplying the weight of a piston (54) and a blade (57) by the square of the number of revolutions of a main compressor body (11), a distance h from the center of the thickness-direction of the piston (54) to a center of gravity (G1) of a compressor unit (10), an inertial moment I around a central axis passing through the center of gravity (G1) of the compressor unit (10), which is the center of rotation when the main compressor body (11) vibrates in a direction tilting towards an accumulator (40), a distance L from the axial center of an inlet pipe (42) of the accumulator (40) to the center of gravity (G1) of the compressor unit (10), and a rated capacity P of a refrigeration device (1) satisfy the condition F × (h / I) × L ≤ 19 × P + 128.
