  • Two-stage compressor with a gas storage chamber between stages and air conditioner having same
    Patent number: 11326603
    Abstract: Disclosed are a compressor and an air conditioner having same. The compressor includes: a first-stage cylinder, including a first-stage compression chamber; and a second-stage cylinder, including a second-stage compression chamber and a gas storage chamber. Refrigerant flowing out of the first-stage compression chamber flows through the storage chamber and enters into the second-stage compression chamber, and a flow area of the gas storage chamber is larger than an area of a gas outlet of the first-stage compression chamber. The compressor effectively solves problems that power consumption of the compressor is increased and performance is reduced due to large resistance loss in the cylinder of the compressor.
