As shown in conjunction with fig. 1 to 4, an embodiment of the present disclosure provides a compressor including: a first cylinder 10, a roller 11, a first slide 12 and a second slide 13, the first cylinder 10 defining a receiving chamber; the roller 11 is eccentrically and rotatably arranged in the accommodating cavity; the first sliding vane 12 is movably arranged on the side wall of the first cylinder 10, and one end of the first sliding vane 12 is abutted with the roller 11; the second sliding vane 13 is movably arranged on the side wall of the first cylinder 10, one end of the second sliding vane 13 is abutted against the roller 11, the first sliding vane 12, the roller 11 and the second sliding vane 13 are matched to divide the accommodating cavity into a first compression cavity 101 and a second compression cavity 104, a first air suction port 102 and a first air exhaust port 103 are arranged on the side wall of the first cylinder 10 corresponding to the first compression cavity 101, and a second air suction port 105 and a second air exhaust port 106 are arranged on the side wall of the first cylinder 10 corresponding to the second compression cavity 104; wherein the first cylinder 10 defines a first passage 141 communicating with both the first intake port 102 and the first exhaust port 103, the first passage 141 being controllably openable and closable; the first cylinder 10 defines a second passage 142 communicating with both the second suction port 105 and the second exhaust port 106, the second passage 142 being controllably openable and closable.

With the embodiment of the present disclosure, as shown in fig. 1 and 2, the first sliding vane 12, the roller 11, the second sliding vane 13 and part of the side walls of the first cylinder 10 enclose a first compression chamber 101 together, and the side wall of the first cylinder 10 corresponding to the first compression chamber 101 is provided with a first air suction port 102 and a first air discharge port 103. When the roller 11 eccentrically rotates in the accommodating chamber, the roller 11 sequentially passes through the first air suction port 102 and the first air discharge port 103, and after the roller 11 passes through the first air suction port 102, the roller 11 divides the first compression chamber 101 into an air inlet area and an air discharge area, the air inlet area is communicated with the first air suction port 102, and the air discharge area is communicated with the first air discharge port 103. As the roller 11 continues to rotate, gas enters the intake zone from the first suction port 102 and gas in the exhaust zone continues to compress and flows out of the first exhaust port 103. Similarly, the first slide 12, the roller 11, the second slide 13 and the other part of the side wall of the first cylinder 10 enclose a second compression cavity 104, and when the roller 11 eccentrically rotates, gas can flow into the second compression cavity 104 from the second air suction port 105, and the gas in the second compression cavity 104 is compressed and flows out from the second air discharge port 106. By providing the first passage 141 and communicating both ends of the first passage 141 with the first suction port 102 and the second suction port 105, respectively. In this way, when the first passage 141 is opened, the first suction port 102 communicates with the first discharge port 103, and the gas in the first compression chamber 101 directly flows back from the first discharge port 103 to the first suction port 102 along the first passage 141 when the roller 11 rotates, so that the compression of the gas in the first compression chamber 101 is not achieved. Similarly, when the second passage 142 is opened, the gas in the second compression chamber 104 cannot be compressed. Thus, the volume of the compression volume of the first cylinder 10 can be controlled by controlling the opening and closing of the first passage 141 and the opening and closing of the second passage 142, thereby realizing the variable volume control of the first cylinder 10. Compared with the compressor in the related art, the embodiment can realize multiple variable capacity without arranging two cylinders, so that the compressor has multiple modes, the number of the cylinders can be reduced, the volume of the compressor is effectively reduced, the cost of the compressor is reduced, and the miniaturization of the compressor can be realized.

Optionally, the side wall of the first cylinder 10 is provided with a first slide groove and a second slide groove, the first slide 12 is movably arranged in the first slide groove, and the second slide 13 is movably arranged in the second slide groove. The compressor further includes: the first spring and the second spring are arranged in the first sliding vane groove, so that one end of the first sliding vane 12, which faces the roller 11, is always in contact with the roller 11; the second spring is disposed in the second slide groove, so that one end of the second slide 13 facing the roller 11 is always abutted against the roller 11.

By providing the first spring and disposing the first spring in the first slide groove in this manner, the first slide 12 can be brought into close contact with the side wall of the roller 11 at any time. Through setting up the second spring and locating the second spring in the second gleitbretter inslot, can make second gleitbretter 13 and the lateral wall of roller 11 in close contact constantly, and then avoid gas to flow away from between roller 11 and first gleitbretter 12 or roller 11 and the second gleitbretter 13 to guarantee the compression effect of compressor.

Optionally, the compressor further comprises: the control assembly 16 is arranged on the first channel 141 and the second channel 142, and is used for controlling the communication or closing of the first channel 141 and the communication or closing of the second channel 142; the passage includes a first channel 141 and a second channel 142, the passage is provided with a limit groove 15, the control component 16 is movably arranged in the limit groove 15, the control component 16 moves between a first position and a second position, the passage is communicated when the control component 16 is in the first position, and the passage is closed when the control component 16 is in the second position.

By arranging the limiting groove 15 in the passage and arranging the control component 16 in the limiting groove 15, the control component 16 can move in the limiting groove 15, so that the control component 16 can control the passage to be opened or closed.

Specifically, the number of the control components 16 is two, the two control components 16 are respectively disposed in the limit groove 15 of the first channel 141 and the limit groove 15 of the second channel 142, and the two control components 16 respectively control the opening or closing of the first channel 141 and the opening or closing of the second channel 142.

Optionally, the control assembly 16 includes: the control pin 161, the first air supply pipeline 163 and the second air supply pipeline 164, wherein the control pin 161 is movably arranged in the limit groove 15; the first air supply pipeline 163 is communicated with the passage and is arranged corresponding to the upper end of the limit groove 15, and is used for filling air into the upper part of the limit groove 15 so as to enable the control pin 161 to move to a first position to enable the passage to be communicated; the second air supply pipeline 164 is communicated with the passage and is arranged corresponding to the lower end of the limit groove 15 and is used for filling air into the lower part of the limit groove 15 so as to enable the control pin 161 to move to the second position to enable the passage to be closed

By adopting the embodiment of the disclosure, by utilizing the first air supply pipeline 163 and the second air supply pipeline 164 to realize the switching of the positions of the control pins 161, compared with the mode of arranging the electromagnetic valve and the like, the problem that the refrigerants in the first passage and the second passage are exploded due to the spark generated by the electromagnetic valve can be avoided, and the influence on the strength and the tightness of the cylinder body of the first cylinder 10 is reduced.

Specifically, as shown in fig. 3, when the control pin 161 is required to be in the first position, the first gas supply line 163 supplies gas so that the control pin 161 moves downward to the first position by the gas, maintaining the passage in a communicated state. When the control pin 161 is required to be in the second position, as shown in fig. 4, the second gas supply line 164 supplies gas so that the control pin 161 moves downward to the second position by the gas to keep the passage closed.

Optionally, the air supply lines include a first air supply line 163 and a second air supply line 164, and the air inlet end of the air supply line includes two air supply lines, one of which communicates with the evaporator 40 and the other of which communicates with the air outlet of the compressor. In this way, the gas supply line can be made to supply low-pressure gas and high-pressure gas.

Optionally, the air inlet pipelines are all provided with valves, and the valves are used for controlling the on-off of the air inlet pipelines.

Thus, by providing a valve in the air intake pipe, the valve can control the on-off of the air intake pipe, and by opening or closing the air intake pipe communicating with the evaporator 40 and the air intake pipe communicating with the air outlet of the compressor, it is possible to control whether the gas flowing into the air intake pipe is low-pressure gas or high-pressure gas.

Specifically, the valve is an electromagnetic valve.

Thus, the opening and closing of the air supply pipeline can be automatically controlled.

Optionally, the inlet line communicating with the evaporator 40 is provided with a one-way valve so that the gas in the inlet line can only flow along the inlet line into the supply line.

Thus, by providing the check valve and providing the check valve to the intake pipe communicating with the evaporator 40, it is possible to avoid the occurrence of a situation in which the high-pressure gas in the other intake pipe flows into the intake pipe communicating with the evaporator 40.

Optionally, the upper part of the limit groove 15 is provided with two air return pipelines, one of which is communicated with the evaporator 40, and the other air return pipeline is communicated with the exhaust pipeline of the compressor, so that the low-pressure gas flows back to the evaporator 40 and the high-pressure gas flows back to the exhaust pipeline of the compressor.

In this way, low pressure gas can flow back to the evaporator 40 along the return line, high pressure gas can flow back to the compressor discharge line along the return line, and gas can flow back to the circulation line without causing a decrease in refrigerant in the circulation line.

Optionally, the lower part of the limit groove 15 is provided with two air return pipelines, one of which is communicated with the evaporator 40, and the other air return pipeline is communicated with the exhaust pipeline of the compressor, so that the low-pressure gas flows back to the evaporator 40 and the high-pressure gas flows back to the exhaust pipeline of the compressor.

In this way, low pressure gas can flow back to the evaporator 40 along the return line, high pressure gas can flow back to the compressor discharge line along the return line, and gas can flow back to the circulation line without causing a decrease in refrigerant in the circulation line.

Optionally, the control assembly 16 further comprises: the elastic piece 162 is arranged in the limit groove 15 and is abutted with the lower end of the control pin 161, and the elastic piece 162 is used for supporting the control pin 161 so that the control pin 161 can block the passage.

With the embodiment of the present disclosure, when the first air supply line 163 and the second air supply line 164 are both in the closed state or the pressure values of the air supplied by the two air supply lines are equal, the control pin 161 moves toward the second position or is maintained at the second position under the action of the elastic member 162, so that the control pin 161 is in the position of closing the passage. This allows the control pin 161 to spring back to the second position under the influence of the elastic member 162 without an external force.

Specifically, the elastic member 162 may be a spring or rubber.

Alternatively, the ratio of the volume of the first compression chamber 101 to the volume of the second compression chamber 104 ranges from 0.65 to 0.8.

By adopting the embodiment of the disclosure, the compression performance of the compressor can be optimized and the energy efficiency of the compressor can be improved by setting the ratio of the volume of the first compression chamber 101 to the volume of the second compression chamber 104 between 0.65 and 0.8.

Specifically, the ratio of the volume of the first compression chamber 101 to the volume of the second compression chamber 104 may be 0.65, 0.7, 0.75, 0.8, etc.

Alternatively, the first air outlet 103 and the second air inlet 105 are disposed on two sides of the first slide sheet 12, and the second air outlet 106 and the first air inlet 102 are disposed on two sides of the second slide sheet 13.

With the embodiment of the present disclosure, as shown in fig. 2, by disposing the first exhaust port 103 and the second intake port 105 on both sides of the first slider 12, and disposing the second exhaust port 106 and the first intake port 102 on both sides of the second slider 13. In this way, the first air suction port 102 and the first air discharge port 103 can be arranged at two ends of the side wall of the first cylinder 10 corresponding to the first compression cavity 101, so that the effective compression volume of the first compression cavity 101 is ensured, and further the working efficiency of the first compression cavity 101 is ensured. Similarly, the effective compression volume of the second compression chamber 104 may be ensured, thereby ensuring the working efficiency of the second compression chamber 104.

Optionally, the compressor further comprises: and a second cylinder 20, the second cylinder 20 being provided independently of the first cylinder 10 for compressing the air supply.

With the embodiment of the present disclosure, by providing the second cylinder 20 and providing the second cylinder 20 separately from the first cylinder 10, that is, the second cylinder 20 has separate suction, compression, and exhaust structures, the second cylinder 20 and the first cylinder 10 can be compressed at the same time. By providing the second cylinder 20, the second cylinder 20 can enhance the energy efficiency of the compressor.

Specifically, the second cylinder 20 is provided with a parallel air supply line 21, and the parallel air supply line 21 is adapted to communicate with the evaporator 40 or the flash evaporator so that the saturated gaseous refrigerant flows into the second cylinder 20 along the suction line.

In this way, by inputting the saturated gaseous refrigerant into the second cylinder 20 by the evaporator 40 or the flash evaporator, the compression efficiency of the compressor can be improved.

For example, the air conditioning system is taken as an example for a refrigerating mode, and the liquid refrigerant flowing out of the condenser 30 is throttled by the throttling device to be changed into a low-temperature and low-pressure wet steam state. At this time, the saturated gas is separated by using the flash evaporator or the plate heat exchanger, and the saturated gas directly flows back to the second cylinder 20 of the compressor along the air suction pipeline to be independently compressed, so that the saturated gas is not mixed with the unsaturated gas to be compressed, the compression efficiency of the pump body of the compressor can be further improved, and the energy efficiency of the low-frequency air conditioning system can be improved by 8% -10% in a refrigerating mode.

Optionally, the second cylinder 20 defines a third compression chamber, the ratio of the volume of the third compression chamber to the volume of the first compression chamber 101 being in the range 0.1-0.3.

By adopting the embodiment of the disclosure, the compression effect of the compressor can be optimized by setting the ratio of the volume of the third compression cavity to the volume of the first compression cavity 101 to be between 0.1 and 0.3, and the energy efficiency of the compressor is improved.

Specifically, the ratio of the volume of the third compression chamber to the volume of the first compression chamber 101 may be 0.1, 0.15, 0.2, 0.25, 0.3, etc.

Optionally, when the working frequency of the compressor is in the first frequency range, the first channel 141 is closed and the second channel 142 is opened to compress the first compression chamber 101 and the second cylinder 20, and when the working frequency of the compressor is increased to the second frequency range, the first channel 141 is opened and the second channel 142 is closed to compress the second compression chamber 104 and the second cylinder 20; when the operating frequency of the compressor increases to the third frequency range, both the first passage 141 and the second passage 142 are closed; wherein the upper threshold of the first frequency range is smaller than the lower threshold of the second frequency range, and the upper threshold of the second frequency range is smaller than the lower threshold of the third frequency range.

Therefore, by adapting different compression volumes when the compressors are in different working frequency ranges, the operation efficiency of the compressors in each working frequency range can be effectively improved, the situations of extreme low frequency and extreme high frequency of the compressors can be avoided, and the reliability of the compressors is improved.

Illustratively, when the operating frequency of the compressor is in a low frequency stage (10-25 Hz) for operation, the first compression chamber 101 of the compressor operates with the second cylinder 20, so that the cylinder compression efficiency and the motor efficiency can be integrally improved during this stage, thereby improving the compressor operation efficiency. The second compression chamber 104 of the compressor operates with the second cylinder 20 when the operating frequency of the compressor is increased to the intermediate operation stage (26-70 Hz), and the first cylinder 10 and the second cylinder 20 of the compressor both operate when the operating frequency of the compressor is increased to the high frequency operation stage (71-120 Hz). Therefore, when the compressors are in different frequency bands to operate, the compressors use different compression volumes, so that the operation efficiency of the compressors can be improved.

The air conditioning system adopting the embodiment of the present disclosure, because of including the compressor according to any one of the embodiments, has the beneficial effects of the compressor according to any one of the embodiments, and will not be described herein.

Optionally, the air conditioning system further comprises: the condenser 30, the evaporator 40 and the parallel air supply line 21, one end of the parallel air supply line 21 is communicated with the evaporator 40, and the other end of the parallel air supply line 21 is communicated with the second cylinder 20 so that saturated gas in the evaporator 40 flows into the second cylinder 20; wherein the compressor, condenser 30 and evaporator 40 are in turn in communication.

By adopting the embodiment of the disclosure, the compressor, the condenser 30 and the evaporator 40 are sequentially communicated, and the compressor, the condenser 30 and the evaporator 40 are sequentially communicated to form a refrigerant circulation loop. By providing the parallel air supply line 21 and communicating both ends of the parallel air supply line 21 with the evaporator 40 and the second cylinder 20, respectively, the saturated gas in the evaporator 40 can be caused to flow into the second cylinder 20 along the parallel air supply line 21, and the compression efficiency of the compressor can be improved.
