[0049] The present disclosure provides a scroll compressor, which includes a shell, a scroll assembly, a gas detection unit and a control unit. The scroll assembly is arranged in the shell to form a compression chamber for compressing refrigerant gas, and is constructed to divide the inner cavity of the shell into a low-pressure area and a high-pressure area.

[0052] For ease of understanding, refer toFigures 1 to 2 , the specific structure and working principle of the scroll compressor disclosed in the present invention are explained in detail in combination with an embodiment.

[0053] like Figures 1 to 2 As shown, the present disclosure provides a scroll compressor, which includes a housing 1, a scroll assembly 2, a gas detection unit and a control unit 4; the housing 1 is provided with an air inlet 11 and an air outlet 12; the scroll assembly 2 is arranged in the housing 1, forming a compression chamber for compressing refrigerant gas, and is constructed to divide the housing 1 into a low-pressure area 13 and a high-pressure area 14, the air inlet 11 is connected to the low-pressure area 13, the air outlet 12 is connected to the high-pressure area 14, and the refrigerant gas in the low-pressure area 13 is configured to flow to the high-pressure area 14 after entering the compression chamber and being compressed. Specifically, in one embodiment of the present disclosure, the scroll assembly 2 includes a movable scroll, a fixed scroll and a motor 21; a compression chamber is formed between the movable scroll and the fixed scroll, and the motor 21 is configured to drive the movable scroll of the scroll assembly 2 to rotate relative to the fixed scroll to compress the refrigerant gas entering the compression chamber.

[0054] The gas detection unit is arranged in the inner cavity of the shell 1, and is configured to obtain the state parameters of the refrigerant gas in the inner cavity of the shell 1; the control unit 4 is signal-connected to the vortex assembly 2 and the gas detection unit, and is configured to control the operation of the vortex assembly 2 based on the state parameters obtained by the gas detection unit.

[0055] That is, during the operation of the scroll compressor of the present disclosure, the external refrigerant gas can enter the low-pressure area 13 through the air inlet 11, and the refrigerant gas in the low-pressure area 13 can enter the compression chamber of the scroll assembly 2, and flow to the high-pressure area 14 after being compressed, and then be discharged from the scroll compressor through the air outlet 12. The gas detection unit can obtain the state parameters of the refrigerant gas in the inner cavity of the shell 1 in real time, and the control unit 4 can control the operation of the scroll assembly 2 based on the state parameters obtained by the gas detection unit.

[0056] In this way, during the operation of the scroll compressor disclosed in the present invention, the gas detection unit of the scroll compressor can monitor the refrigerant gas state in the inner cavity of the shell 1, and the control unit 4 of the scroll compressor itself can control the operation of the scroll assembly 2 through the refrigerant gas state parameters obtained by the gas detection unit, thereby effectively avoiding various working hazards during the operation of the scroll compressor, ensuring that the scroll compressor can work normally, and extending the service life of the scroll compressor.

[0057] like Figures 1 to 2As shown, the present disclosure provides a scroll compressor, which includes a shell 1, a scroll assembly 2, a first detection unit 31, a second detection unit 32 and a control unit 4; the shell 1 is provided with an air inlet 11 and an air outlet 12; the scroll assembly 2 is arranged in the shell 1, forming a compression chamber for compressing refrigerant gas, and is constructed to divide the shell 1 into a low-pressure area 13 and a high-pressure area 14, the air inlet 11 is connected with the low-pressure area 13, the air outlet 12 is connected with the high-pressure area 14, and the refrigerant gas in the low-pressure area 13 is configured to enter the compression chamber, be compressed and then flow to the high-pressure area 14.

[0058] That is, during the operation of the scroll compressor of the present disclosure, the external refrigerant gas can enter the low-pressure area through the air inlet, the refrigerant gas in the low-pressure area can enter the compression chamber of the scroll assembly, and after being compressed, it flows to the high-pressure area, and then is discharged from the scroll compressor through the air outlet. The gas detection unit can obtain the state parameters of the refrigerant gas in the inner cavity of the shell in real time, and the control unit can control the operation of the scroll assembly based on the state parameters obtained by the gas detection unit.

[0059] In this way, during the operation of the scroll compressor disclosed in the present invention, the first detection unit of the scroll compressor can monitor the refrigerant gas state in the low-pressure area, the gas detection unit can monitor the refrigerant gas state in the inner cavity of the shell, and the control unit of the scroll compressor itself can control the operation of the scroll component through the refrigerant gas state parameters obtained by the gas detection unit, thereby effectively avoiding various working hidden dangers during the operation of the scroll compressor, ensuring that the scroll compressor can work normally, and extending the service life of the scroll compressor.

[0060] In one embodiment of the present disclosure, the gas detection unit includes a first detection unit 31 and a second detection unit 32, the first detection unit 31 is arranged in the low-pressure zone 13, and is configured to obtain the state parameters of the refrigerant gas in the low-pressure zone 13; the second detection unit 32 is arranged in the high-pressure zone 14, and is configured to obtain the state parameters of the refrigerant gas in the high-pressure zone 14; the control unit 4 is signal-connected with the vortex assembly 2, the first detection unit 31 and the second detection unit 32, and is configured to control the operation of the vortex assembly 2 based on the state parameters obtained by the first detection unit 31 and the second detection unit 32.

[0061] That is, during the operation of the scroll compressor disclosed in the present invention, external refrigerant gas can enter the low-pressure zone 13 through the air inlet 11, the refrigerant gas in the low-pressure zone 13 can enter the compression chamber of the scroll assembly 2, and after being compressed, flow to the high-pressure zone 14, and then be discharged from the scroll compressor from the air outlet 12; the first detection unit 31 can obtain the state parameters of the refrigerant gas in the low-pressure zone 13 in real time; the second detection unit 32 can obtain the state parameters of the refrigerant gas in the high-pressure zone 14, and the control unit 4 can control the operation of the scroll assembly 2 based on the state parameters obtained by the first detection unit 31 and the second detection unit 32.

[0062] In this way, during the operation of the scroll compressor disclosed in the present invention, the first detection unit 31 of the scroll compressor can monitor the refrigerant gas state in the low-pressure area 13, and the second detection unit 32 can monitor the refrigerant gas state in the high-pressure area 14. The control unit 4 of the scroll compressor itself can control the operation of the scroll assembly 2 through the refrigerant gas state parameters obtained by the first detection unit 31 and the second detection unit 32, thereby effectively avoiding various operating hazards during the operation of the scroll compressor, ensuring that the scroll compressor can work normally, and extending the service life of the scroll compressor.

[0063] like Figure 2 As shown, in one embodiment of the present disclosure, the first detection unit 31 is configured to obtain the temperature parameters of the refrigerant gas in the low-pressure area 13; the second detection unit 32 is configured to obtain the temperature parameters of the refrigerant gas in the high-pressure area 14, and the control unit 4 is configured to control the operation of the scroll assembly 2 based on the temperature parameters obtained by the first detection unit 31 and the second detection unit 32. That is, during the operation of the scroll compressor of the present disclosure, the first detection unit 31 can obtain the temperature parameters of the refrigerant gas in the low-pressure area 13 in real time; the second detection unit 32 can obtain the temperature parameters of the refrigerant gas in the high-pressure area 14, and the control unit 4 can control the operation of the scroll assembly 2 based on the temperature parameters obtained by the first detection unit 31 and the second detection unit 32, so that when the intake temperature and exhaust temperature of the scroll compressor of the present disclosure are abnormal, the control unit 4 can timely control the scroll assembly 2 to shut down, or change the working state of the scroll assembly 2, so as to avoid the damage of the scroll compressor of the present disclosure during operation, ensure the working safety of the scroll compressor, and extend the service life of the scroll compressor.

[0064] In an embodiment of the present disclosure, the control unit 4 is configured to control the scroll assembly 2 to shut down when the temperature parameter of the refrigerant gas in the high-pressure region 14 obtained by the second detection unit 32 is higher than a second preset value. In this way, when the exhaust temperature of the scroll compressor in the present disclosure is too high, the scroll assembly 2 can be timely controlled to shut down, effectively avoiding the lubrication performance of the lubricating oil from decreasing due to the high exhaust temperature causing the scroll compressor to work under a high load for a long time, shortening the service life of the scroll compressor, and even burning out the motor coil of the scroll compressor.

[0065] In another embodiment of the present disclosure, the first detection unit 31 is configured to obtain the pressure parameter of the refrigerant gas in the low-pressure region 13; the second detection unit 32 is configured to obtain the pressure parameter of the refrigerant gas in the high-pressure region 14; the control unit 4 is configured to control the scroll assembly 2 to shut down when the pressure parameter of the refrigerant gas in the low-pressure region 13 obtained by the first detection unit 31 is higher than a third preset value and / or the pressure parameter of the refrigerant gas in the high-pressure region 14 obtained by the second detection unit 32 is higher than a fourth preset value.

[0066] In this way, during the operation of the scroll compressor in the present disclosure, when the refrigerant pressure in the low-pressure region 13 and / or the high-pressure region 14 is too high, the scroll assembly 2 is timely controlled to shut down, thereby avoiding situations such as air leakage or even explosion of the scroll compressor caused by the excessive refrigerant pressure in the low-pressure region 13 and / or the high-pressure region 14, ensuring the working safety of the scroll compressor, and avoiding potential safety hazards.

[0067] In an embodiment of the present disclosure, the control unit 4 is configured to obtain the suction superheat degree of the scroll compressor based on the temperature parameter and the pressure parameter of the refrigerant gas in the low-pressure region 13 obtained by the first detection unit 31, and is configured to control the scroll assembly 2 to shut down when the suction superheat degree is lower than a first preset value.

[0068] Specifically, the suction superheat degree = the temperature of the refrigerant gas in the low-pressure region 13 - the saturation temperature corresponding to the pressure of the refrigerant gas in the low-pressure region 13. The control unit 4 can obtain the suction superheat degree of the scroll compressor based on the temperature parameter and the pressure parameter of the refrigerant gas in the low-pressure region 13, and control the scroll assembly 2 to shut down when the suction superheat degree is lower than a first preset value.

[0069] In this way, when the suction superheat degree is too low, it can effectively avoid the situation that the refrigerant gas contains incompletely evaporated liquid droplets, causing liquid hammer and damaging the scroll assembly 2. When the suction superheat degree is too low, the scroll assembly 2 is timely controlled to shut down, thereby avoiding the damage of the scroll compressor in the present disclosure during the operation process, ensuring the working safety of the scroll compressor, and prolonging the service life of the scroll compressor.

[0070] Specifically, such asFigure 2 As shown, in one embodiment of the present disclosure, openings can be set at positions corresponding to the low-pressure area 13 and the high-pressure area 14 of the shell 1, and a first detection unit 31 can be installed at a corresponding position of the low-pressure area 13, and a second detection unit 32 can be installed at a corresponding position of the high-pressure area 14; the first detection unit 31 and the second detection unit 32 can be integrated pressure and temperature sensors, which convert pressure and temperature signals into resistance value signals and send them to the control unit 4.

[0071] like Figure 2 As shown, in one embodiment of the present disclosure, an oil storage chamber 15 is provided at the bottom of the scroll compressor; the oil storage chamber 15 is constructed to contain lubricating oil; a lubricating oil detection unit 33 is provided in the oil storage chamber 15; the lubricating oil detection unit 33 is configured to obtain the state parameters of the lubricating oil in the oil storage chamber 15; the control unit 4 is also connected to the detection unit signal, and is configured to control the operation of the scroll assembly 2 based on the state parameters of the lubricating oil in the oil storage chamber 15 obtained by the lubricating oil detection unit 33.

[0072] In this way, during the operation of the scroll compressor disclosed in the present invention, the lubricating oil detection unit 33 of the scroll compressor can obtain the state parameters of the lubricating oil in the oil storage chamber 15 in real time, and the control unit 4 can control the operation of the scroll assembly 2 based on the state parameters of the lubricating oil in the oil storage chamber 15 obtained by the lubricating oil detection unit 33, thereby effectively ensuring that the various components of the scroll compressor disclosed in the present invention can be effectively lubricated, avoiding poor lubrication, causing wear or even damage to parts, and effectively extending the service life of the scroll compressor.

[0073] In one embodiment of the present disclosure, the lubricating oil detection unit 33 is configured to obtain the oil level parameters of the lubricating oil in the oil storage chamber 15; the control unit 4 is configured to control the vortex assembly 2 to shut down when the oil level parameters of the lubricating oil in the oil storage chamber 15 obtained by the lubricating oil detection unit 33 are lower than the fifth preset value.

[0074] In this way, during the operation of the scroll compressor, the lubricating oil detection unit 33 can obtain the oil level of the lubricating oil in the oil storage chamber 15 in real time, and the control unit 4 can timely control the scroll assembly 2 to shut down when the oil level in the oil storage chamber 15 is too low, that is, when the amount of lubricating oil is too low, to avoid the various components of the scroll compressor from being poorly lubricated. In addition, the control unit 4 can also send an alarm signal in time when the oil level in the oil storage chamber 15 is too low to remind the maintenance personnel to add lubricating oil.

[0075] In another embodiment of the present disclosure, the lubricating oil detection unit 33 is configured to obtain whether it is immersed in the lubricating oil in the oil storage cavity 15; the control unit 4 is configured to control the scroll assembly 2 to stop operating when the lubricating oil detection unit 33 is not immersed in the lubricating oil in the oil storage cavity 15. In this way, during the operation of the scroll compressor, the lubricating oil detection unit 33 can obtain in real time whether it is immersed in the lubricating oil in the oil storage cavity 15, and the control unit 4 can control the scroll assembly 2 to stop operating when the lubricating oil detection unit 33 is not immersed in the lubricating oil in the oil storage cavity 15, which can also avoid the situation of poor lubrication of various components of the scroll compressor.

[0076] Moreover, compared with the above-mentioned lubricating oil detection unit 33 for detecting the oil level, the lubricating oil detection unit 33 that only needs to detect whether it is immersed in the lubricating oil in the oil storage cavity 15 has a lower manufacturing cost, thereby further reducing the production cost of the scroll compressor of the present disclosure. However, when using the lubricating oil detection unit 33 for detecting whether it is immersed in the lubricating oil in the oil storage cavity 15, it is necessary to ensure that the scroll compressor is fixed and vertically arranged to avoid errors caused by the setting angle.

[0077] In one embodiment of the present disclosure, the lubricating oil detection unit 33 is configured to obtain the oil temperature parameter of the lubricating oil in the oil storage cavity 15; the control unit 4 is configured to control the scroll assembly 2 to stop operating when the oil temperature parameter of the lubricating oil in the oil storage cavity 15 obtained by the lubricating oil detection unit 33 is higher than the sixth preset value.

[0078] In this way, when the oil temperature of the lubricating oil in the scroll compressor of the present disclosure is too high due to reasons such as too high intake air temperature and abnormal wear of parts, the control unit 4 can timely control the scroll assembly 2 to stop operating, effectively avoiding the scroll compressor from continuing to operate under abnormal conditions, so as to avoid damage to the scroll compressor and potential safety hazards.

[0079] In one embodiment of the present disclosure, the lubricating oil detection unit 33 is configured to obtain the viscosity parameter of the lubricating oil in the oil storage cavity 15; the control unit 4 is configured to control the scroll assembly 2 to stop operating when the viscosity parameter of the lubricating oil in the oil storage cavity 15 obtained by the lubricating oil detection unit 33 is higher than the seventh preset value.

[0080] In this way, the lubricating oil detection unit 33 can obtain the viscosity of the lubricating oil in the oil storage cavity 15 in real time, and the control unit 4 can timely control the scroll assembly 2 to stop operating when the viscosity of the lubricating oil in the oil storage cavity 15 is too high, avoiding the situation of poor lubrication of various components of the scroll compressor. In addition, the control unit 4 can also timely send an alarm signal when the viscosity in the oil storage cavity 15 is too high to remind the maintenance personnel to replace the new lubricating oil in time.

[0081] It is understandable that the viscosity of the lubricating oil in the oil storage chamber 15 can be directly obtained not only by using the above-mentioned device, but also indirectly obtained by other means. Therefore, in one embodiment of the present disclosure, the gas detection unit includes a first detection unit 31, which is arranged in the low-pressure area 13 and is configured to obtain the pressure parameters of the refrigerant gas in the low-pressure area 13; the control unit 4 is configured to obtain the viscosity parameters of the lubricating oil in the oil storage chamber 15 based on the pressure parameters of the refrigerant gas in the low-pressure area 13 obtained by the first detection unit 31 and the oil temperature parameters of the lubricating oil in the oil storage chamber 15 obtained by the lubricating oil detection unit 33, and when the viscosity parameters of the lubricating oil in the oil storage chamber 15 are higher than the seventh preset value, the scroll assembly 2 is controlled to shut down.

[0082] In this way, the scroll compressor disclosed in the present invention can indirectly obtain the viscosity parameters of the lubricating oil in the oil storage chamber 15 based on the pressure parameters of the refrigerant gas in the low-pressure zone 13 and the oil temperature parameters of the lubricating oil in the oil storage chamber 15, thereby effectively reducing the difficulty of obtaining the viscosity parameters of the lubricating oil in the oil storage chamber 15.

[0084] In this way, during the operation of the scroll compressor disclosed in the present invention, the electrical detection unit of the scroll compressor can monitor the working state of the motor 21 to ensure that the motor 21 can maintain normal operation, thereby effectively avoiding various working hazards during the operation of the motor 21, ensuring that the scroll compressor can work normally, and extending the service life of the scroll compressor.

[0085] Furthermore, in one embodiment of the present disclosure, the electrical detection unit is configured to obtain the temperature parameters of the motor 21 in the working state; the control unit 4 is signal-connected to both the scroll assembly 2 and the electrical detection unit, and is configured to control the operation of the scroll assembly 2 based on the temperature parameters obtained by the electrical detection unit. That is, during the operation of the scroll compressor of the present disclosure, the electrical detection unit of the scroll compressor can monitor the operating temperature of the motor 21 to ensure that the motor 21 can operate within the normal temperature range, thereby effectively avoiding overheating of the motor 21 during operation, avoiding burning of the motor 21 due to overheating, and effectively extending the service life of the motor 21.

[0086] Furthermore, in one embodiment of the present disclosure, the electrical detection unit is configured to obtain the current parameters of the motor 21 in the working state; the control unit 4 is signal-connected to both the scroll assembly 2 and the electrical detection unit, and is configured to control the operation of the scroll assembly 2 based on the current parameters obtained by the electrical detection unit. That is, during the operation of the scroll compressor of the present disclosure, the electrical detection unit of the scroll compressor can monitor the operating current of the motor 21 to ensure that the motor 21 can operate within the current temperature range, and when the current is too large during the operation of the motor 21, the scroll assembly 2 is promptly controlled to shut down to prevent the motor 21 from continuing to operate in the state of excessive current.
