Abstract
A compressor and a refrigeration device are provided. The compressor has a housing, a first cylinder, a first piston, a second cylinder and a second piston. The housing has a first air outlet port and a second air outlet port. The first cylinder has an accommodating cavity, and the first piston is eccentrically disposed in the first accommodating cavity. The second cylinder has a second accommodating cavity, and the second piston is eccentrically disposed in the second accommodating cavity.
Claims13
A compressor comprising:
- a housing, wherein a first air outlet port and a second air outlet port not in communication with each other are disposed in the housing;
- a first cylinder and a first piston, wherein the first cylinder is provided with a first accommodating cavity, and the first piston is eccentrically disposed in the first accommodating cavity;
- and
- a second cylinder and a second piston, wherein the second cylinder is provided with a second accommodating cavity, and the second piston is eccentrically disposed in the second accommodating cavity,
- wherein:
- an inner diameter of the first cylinder is D1, an eccentric distance of the first piston relative to the first accommodating cavity is e1, a height of the first cylinder is H1, and an exhaust pressure of the first cylinder is P1, and the first cylinder is configured to exhaust gas through the first air outlet port;
- an inner diameter of the second cylinder is D2, an eccentric distance of the second piston relative to the second accommodation cavity is e2, a height of the second cylinder is H2, and an exhaust pressure of the second cylinder is P2, and the second cylinder is configured to exhaust gas through the second air outlet port;
- and
- P1<P2, 0.6≤(e1×(D1−e1)×H1)÷(e2×(D2−e2)×H2)≤1.9.
