ROTARY COMPRESSOR AND COMPRESSION UNIT THEREOF, AND AIR CONDITIONER

摘要

A compression device includes an air cylinder (31); an upper bearing (4) and a lower bearing (5); a piston (71) which defines a working space; a first slide vane (81) and a second slide vane (82) which separate the working space into a first and a second working chamber; a first air suction port (101) and a second air suction port (102) both of which are in communication with the working space; and a first air discharge port (91) and a second air discharge port (92) both of which are in communication with the working space. The first and the second air suction port satisfy the following condition: 0.25≦(V1/S1)*(S2/V2)≧4, where V1 and V2 are respectively the maximum volume of the first and the second working chamber, and S1 and S2 are respectively the opening area of the first and the second air suction port.

主权项

1. A compression device of a rotary compressor, comprising:
an air cylinder being hollow and having an open top portion and an open bottom portion, wherein a first sliding vane slot and a second sliding vane slot are formed in the air cylinder; an upper bearing and a lower bearing respectively provided on the top portion and the bottom portion of the air cylinder, so as to define a chamber together with the air cylinder; a piston actuated by an eccentric crankshaft, provided within the chamber eccentrically and being rollable along an inner wall of the chamber, wherein a working space is defined between the piston and the inner wall of the chamber; a first sliding vane and a second sliding vane, wherein the first sliding vane and the second sliding vane are provided respectively within the first sliding vane slot and the second sliding vane slot movably, first ends of the first sliding vane and the second sliding vane both extend into an interior of the chamber and abut against the piston, and the first sliding vane and the second sliding vane separate the working space into a first working chamber and a second working chamber; a first air suction port and a second air suction port, wherein the first air suction port and the second air suction port are both in communication with the working space, and the first air suction port is provided to be adjacent to the first sliding vane slot and the second air suction port is provided to be adjacent to the second sliding vane slot; a first air discharge port and a second air discharge port, wherein the first air discharge port and the second air discharge port are both in communication with the working space, and the first air discharge port is provided to be adjacent to the second sliding vane slot and the second air discharge port is provided to be adjacent to the first sliding vane slot; wherein the first air suction port and the second air suction port are configured to satisfy a following condition:0.25≤V1S1*S2V2≤4 wherein V1 represents a maximum volume of the first working chamber, V2 represents a maximum volume of the second working chamber, S1 represents an opening area of the first air suction port, and S2 represents an opening area of the second air suction port.
