Embodiment 1

[0033] figure 1 shows a schematic structural view of the compressor of this embodiment, figure 2 shows a schematic structural view of the pump body part of the compressor of this embodiment, image 3 show figure 2 Enlarged view of the structure at A.

[0034] combine Figures 1 to 3 As shown, the compressor of this embodiment includes a first compression part 10 , a second compression part 20 and an intermediate channel 30 communicating with the discharge port of the first compression part 10 and the suction port of the second compression part 20 .

[0035] The first port of the middle passage 30 communicates with the exhaust port of the first compression part 10, the second port of the middle passage 30 communicates with the suction port of the second compression part 20, and the peripheral wall of the middle passage 30 is also provided with an enthalpy supplement The flow area of ​​the air port 34 and the position where the enthalpy-increasing air supply port 34 is pro...

Embodiment 2

[0067] Figure 5 A schematic structural diagram of the compressor of this embodiment is shown. The first port of the middle passage 30 communicates with the exhaust port of the first compression part 10, the second port of the middle passage 30 communicates with the suction port of the second compression part 20, and the middle passage 30 includes The first channel section extending from the air supply port, the flow area of ​​the first channel section 31 gradually decreases along the direction from the first port to the enthalpy-increasing air supply port.

[0068] The middle channel 30 also includes a second channel section extending from the second port to the enthalpy-increasing air supply port, and the flow area of ​​the second channel section gradually decreases along the direction from the second port to the enthalpy-increasing air supply port.

[0069] The middle passage 30 also includes a third passage section arranged between the first passage section and the second...

Embodiment 3

[0078] Image 6 A schematic structural diagram of a compressor showing a third embodiment of the present invention; Figure 7 show Image 6 Enlarged view of the structure at B.

[0079] combine Image 6 with Figure 7 It can be seen that the difference between this embodiment and the first and second embodiments is that the middle channel 30 is located outside the shell assembly 52 of the compression molding machine.

[0080] The compressor also includes a first connecting pipeline and a second connecting pipeline, the first connecting pipeline is connected to the first port and extends to the exhaust port of the first compression part 10 inside the shell assembly 52; the second connecting pipeline , is connected with the second port and extends to the inside of the housing assembly 52 to connect to the suction port of the second compression part 20 .

[0081] The middle passage 30 between the first compression part 10 and the second compression part 20 is located outside...

Abstract

The invention provides a compressor and an air conditioner with same. The compressor comprises a first compression part with an exhaust port, a second compression part with an air suction port, and an intermediate passage with a first port and a second port, wherein the first port communicates with the exhaust port of the first compression part, the second port communicates with the air suction port of the second compression part, enthalpy increasing air supply openings are further formed in the circumferential wall of the intermediate passage, and the circulation area of a position, provided with the enthalpy increasing air supply opening, of the intermediate passage is smaller than the circulating area of the first port, so that a cold medium can be guided to the intermediate passage from the enthalpy increasing air supply openings by utilizing Bernoulli effect, thus solving the problem that the cylinder of the second stage of compression part cannot timely absorb enthalpy supplementing air.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a compressor and an air conditioner with the same. Background technique [0002] In the existing two-stage enthalpy-increasing compressor, the exhaust air from the first-stage compression part is mixed with the enthalpy-increasing supplementary air after the first throttling, and then used as the suction air for the second-stage compression. The exhaust gas of the first-stage compression part generally enters the suction port of the cylinder of the second-stage compression part through the circulation channel in the compressor pump body assembly; the enthalpy-enhancing air supply after the first throttling is generally through the flange or the second The enthalpy-increasing air port on the cylinder of the first-stage compression part enters the suction port of the cylinder of the second-stage compression part and mixes with the exhaust gas of the first-stage compression part. Th...
