As depicted in figs. 1 and 2, the first cylinder 20 and second that the compressor of the present embodiment includes housing 10, is oppositely arranged
Cylinder 30, hybrid chamber 40 and air supply passage 50.Wherein, housing 10 is provided with gas supplementing opening 11, the first cylinder 20 includes first
Cylinder body 23 and be arranged on the first air entry 21 and first row gas port 22 on the first cylinder body 23.Second cylinder 30 includes the second cylinder body
32 and be arranged on the second cylinder body 32 second air entry 31 and second exhaust port.Second exhaust port passes through hybrid chamber 40 and the first air-breathing
Mouth 21 connection.The first end of air supply passage 50 is connected with gas supplementing opening 11, and the second end of air supply passage 50 is connected with hybrid chamber 40.Mend
Gas passage 50 be at least partially formed in the first cylinder body 23 so that the work of fluid in air supply passage 50 and the first cylinder 20
Fluid heat transfer in chamber.
The technical scheme of application the present embodiment, when cold-producing medium stream enters air supply passage 50, the temperature in the first cylinder 20 is led to
Cross the first cylinder body 23 and pass to the cold-producing medium in air supply passage 50.Namely said structure achieves the heating effect of centering compression refrigerant
Really, the mass dryness fraction of compression refrigerant, reduces band liquid measure, prevents from causing liquid hammer to the first cylinder 20 and in improving.Therefore the present embodiment
The cold-producing medium mass dryness fraction that technical scheme solves in the hybrid chamber of compressor of the prior art is low, and easily causes liquid to high pressure cylinder
Hit the problem of phenomenon.
As described in Figure 2, in the technical scheme of the present embodiment, the type of flow of compression mechanical part internal refrigeration storage agent is：Come
Enter the second air entry 31 from the cold-producing medium of the low-temp low-pressure of system evaporator through knockout, air-breathing is compressed through the second cylinder 30
Form low-pressure stage afterwards to be vented and enter hybrid chamber 40.In system, the tonifying Qi of pressure enters hybrid chamber 40 through air supply passage 50,
After the tonifying Qi of middle pressure is mixed with the exhaust of the second cylinder 30, well the first air entry 21 enters the first cylinder 20, and the first cylinder 20 will freeze
Form hiigh pressure stage after agent compression to be vented and discharge outside compressor.
As shown in Fig. 2 in the technical scheme of the present embodiment, the first cylinder body 23 is provided with the first hole section interconnecting
231 and second hole section 232.First hole section 231 is extended to the surface of lateral wall of the first cylinder body 23 and is connected with gas supplementing opening 11, the
Two hole sections 232 are extended to the end face of the first cylinder body 23 and are connected with hybrid chamber 40.First hole section 231 and the second hole section 232 are formed
Air supply passage 50.Specifically, in system, pressure tonifying Qi enters in the first cylinder body 23 by the lateral wall of the first cylinder body 23, hybrid chamber
40 ends being arranged on the first cylinder body 23.Can be rounding off or right angle between first hole section 231 and the second hole section 232
Transition, the first hole section 231 and the second hole section 232 make to press the flow path of tonifying Qi that deviation occurs in system, and so that pressure in system is mended
Gas is from the wall flow of the first cylinder body 23 is to the end wall of the first cylinder body 23.
As shown in figure 3, in the technical scheme of the present embodiment, the first cylinder 20 also includes being arranged on the first cylinder body 23
Vane slot 24, the first hole section 231 and the second hole section 232 are arranged on the side deviating from vane slot 24 of first row gas port 22.At this
In the technical scheme of embodiment, in order to improve the heat exchange efficiency of the first cylinder body 23 and middle compression refrigerant, the first hole section 231 and second
Need to meet certain dimensional requirement between hole section 232 and first row gas port 22 and the first cylinder body 23, specific as follows：
Specifically, on the first cylinder body 23, first row gas port 22 and the first hole section 231 and the second hole section 232 have a certain degree
A.This angle determines the position that air supply passage 50 is placed in the first cylinder body 23 circumference.When air supply passage 50 is disposed close to inhale
During gas compression chamber side, because the first cylinder 20 does not start to compress, its temperature and low-pressure stage exhaust are close, with the middle temperature difference pressing tonifying Qi relatively
Little, heat exchange amount is little, the mass dryness fraction of hiigh pressure stage air-breathing is affected little.When tonifying Qi band liquid measure is larger, easily valve block is caused to clash into contracting
Its service life short, and the first cylinder 20 is caused with liquid hammer impact overall performance.When air supply passage 50 is disposed close to exhaust pressure
During the side of contracting chamber, because exhaust compression chamber internal temperature is higher, larger with the middle pressure tonifying Qi temperature difference, heat exchange amount is big.By the first cylinder 20
In the high-temperature heating of compression chamber, compression refrigerant, to improve its mass dryness fraction, reduces band liquid measure, prevents from causing liquid hammer to tonifying Qi check device,
The mass dryness fraction of hiigh pressure stage air-breathing also can be improved simultaneously, prevent from causing liquid hammer to the first cylinder 20.Therefore, air supply passage 50 should be placed on
Near the position of exhaust compression chamber, particular location relation is as follows.

Structure one side is easy to process, and is on the other hand easy to calculate and determines angle A.
Additionally, for ensure the first cylinder 20, air supply passage 50 and first cylinder body sufficiently large with the heat exchange amount of air supply passage 50
23 inner circles should be in rational scope apart from size B.The more big then heat exchange amount of size B is less, too little, leads to the first cylinder body 23
Inner circle circularity and stress variation influence reliability.
It is preferred that the centerline parallel of the center line of the second hole section 232 and the first cylinder body 23.Second hole section 232
The distance of the madial wall to the first cylinder body 23 for the center line is in the range of 3 to 5 millimeters.Said structure one side is easy to the second hole
Section 232 is processed, and is on the other hand easy to calculate and determines size B.
