[0031] The object of the present invention is to provide a compressor and a temperature control device to solve the problem that the existing compressor structure cannot be installed with different specifications and cannot control any system or multiple systems to work simultaneously.

[0032] Those skilled in the art will understand that existing compressors can usually only control the operation of a specific system. Taking the air-conditioning system as an example, after the existing compressor controls the air-conditioning system to complete dehumidification, it needs to use electric heating to reach the required temperature. The humidity and temperature cannot be controlled independently, which makes it impossible for the air-conditioning system to fully utilize the compressor. It also affects the user experience between dehumidification and heating to the required temperature. Based on this, the present application connects two compressor subsystems through a liquid reservoir, and controls different external systems through different compressor subsystems, thereby realizing independent control between different systems, broadening the application scenarios while also improving the user experience.

[0033] Please refer to Figure 1 and Figure 2 The present invention provides a compressor, comprising: at least two compressor subsystems; a compressor subsystem (not shown in the figure) comprises a compressor subunit 10 and a liquid reservoir 20 that are paired with each other, and the compressor subunit 10 is connected to the compressor subunit 10 in another compressor subsystem through the liquid reservoir 20; the compressor subsystems operate independently of each other; at the same time, the liquid reservoir 20 has a connection end 210 and an air inlet end 220, the connection end 210 is connected to the paired compressor subunit 10, and the air inlet end 220 is used to connect to an external system; different compressor subsystems are respectively connected to different external systems through the paired liquid reservoir 20 to achieve control of different external systems (not shown in the figure). It can be understood by those skilled in the art that the control of the external system by the compressor subsystem is mainly achieved by driving the circulation of the refrigerant. The multiple compressor subsystems in this embodiment can be matched with different types of compressors and suitable for different types of refrigerants to control different external systems, thereby achieving independent operation between the compressor subsystems. It should be noted that in Figure 1 In the illustrated example, the compressor subunit 10 is a cylindrical component comprising a housing and a specific compressor component located within the housing. The accumulator 20 is a tubular component having a connecting end 210, an air inlet end 220, and a barrel 230. The barrel 230 connects the connecting end 210 and the air inlet end 220. The connecting end 210 is connected to the corresponding compressor subunit 10, and the air inlet end 220 is connected to an external system. The barrel 230 is primarily used for gas-liquid separation, filtration, refrigerant buffering, and storage. In this embodiment, the connection between the two compressor subsystems is achieved through configuration. The barrel 230 is in the shape of an arc with a certain curvature and is located on the outer wall of the compressor subunit 10 and arranged along its circumference. In some other embodiments, the accumulator 20 and the compressor subunit 10 may also be components of other shapes. Those skilled in the art may configure them according to actual conditions, and this embodiment does not limit this.

[0034] So configured, the compressor provided by the present application includes multiple compressor subsystems, and the compressor subsystem includes a compressor subunit 10 and a liquid reservoir 20. The liquid reservoir 20 is used to connect the compressor subunits 10 located in the two compressor subsystems. At the same time, the liquid reservoir 20 is used to connect the compressor subunit 10 and the external system. Different compressor subsystems work independently of each other. Therefore, the compressor provided by the present application is no longer limited to controlling the operation of only one specific system. It can select compressor subsystems of different specifications and different refrigerants according to needs, and can also control any system to work, or control multiple different systems to work at the same time, further broadening the application scenarios of the compressor; in addition, compared with the existing compressor that sets the liquid reservoir 20 on the side wall of the shell, this embodiment uses the liquid reservoir 20 as a connecting part between the two compressor subsystems, making the liquid reservoir 20 more solid and saving a certain amount of assembly space, and can be applied to more application scenarios.

[0035] As an optional embodiment, please refer to Figure 1 and Figure 2 The liquid reservoir 20 is provided with a first connecting portion (not shown) and a second connecting portion (not shown) arranged opposite each other. The first connecting portion is connected to the corresponding compressor subunit 10, and the second connecting portion is connected to the compressor subunit 10 in another compressor subsystem. Compared to placing the liquid reservoir 20 on the side wall of the compressor, this embodiment uses the liquid reservoir 20 as the connecting portion between the two compressor subsystems, which reduces the required assembly space for the liquid reservoir 20 and is suitable for applications with limited assembly space. At the same time, the liquid reservoir 20 is also more secure and will not loosen during the operation of the compressor, reducing safety risks. It should be noted that in order to ensure that the compressor subsystem can operate independently, the two compressor sub-units 10 should be completely separated and not affect each other. Therefore, the liquid reservoir 20 may also include a partition (not shown in the figure), and the two oppositely arranged surfaces on the partition are the first connection part and the second connection part, or the liquid reservoir 20 can be directly processed into a plate-like component, and its two oppositely arranged surfaces are the first connection part and the second connection part. In other embodiments, the first connection part and the second connection part may also be protrusions on two oppositely arranged surfaces of the liquid reservoir 20. Those skilled in the art may configure the first connection part and the second connection part according to actual conditions, and this embodiment does not limit this.

[0036] Please refer to Figures 2 to 5 , the first connection portion and the second connection portion are arranged opposite to each other along the axial direction X of the compressor subunit 10, the first connection portion is connected to the bottom surface of the paired compressor subunit 10, and the second connection portion is connected to the top surface of the compressor subunit 10 in another compressor subsystem. As a preferred embodiment, the first connection portion and the second connection portion are arranged opposite to each other along the axial direction X (i.e. Figures 1 to 5The compressor subunits 10 are arranged in sequence along their own axial direction X, which can ensure the installation stability between the compressor subunits 10 and the output conversion rate of the compressor subunits 10; and for some narrow and long working scenes, the first connecting portion and the second connecting portion can also be arranged along the radial direction of the compressor subunit 10 (i.e. Figures 1 to 5 The compressor subunits 10 are arranged in a relative manner along their own radial directions. Of course, in other embodiments, the compressor subunits 10 can also be arranged in other directions, and those skilled in the art can configure this according to actual conditions.

[0037] In an alternative embodiment, please refer to Figures 2 to 5 The compressor further includes a foot 40, which is arranged below the compressor subsystem located at the bottom along the axial direction X of the compressor subunit 10, the first connection portion is connected to the paired compressor subunit 10, and the second connection portion is connected to the foot 40. Furthermore, the compressor further includes an upper shell cover 50, which is arranged above the compressor subsystem located at the top along the axial direction X of the compressor subunit 10. It should be noted that, in this embodiment, the liquid reservoir 20 in the compressor subsystem is located below the compressor subunit 10, and the compressor subsystem located at the bottom needs to be connected to the foot 40 through the liquid reservoir 20 at its bottom for easy fixation and installation, while the compressor subsystem located at the top needs to be connected to the upper shell cover 50 at its top to form a closed and independent space. Correspondingly, as another optional embodiment, the liquid reservoir 20 in the compressor subsystem is located above the compressor subunit 10, then the compressor subsystem located at the bottom needs to be connected to the base 40 at its bottom, and the compressor subsystem located at the top needs to be connected to the upper shell cover 50 at its top through the liquid reservoir 20. This embodiment does not impose any restrictions on this.

[0038] As an alternative embodiment, the compressor subsystem further includes an exhaust unit 30. In the compressor subsystem located at the top along the axial direction X of the compressor subunit 10, the exhaust unit 30 is disposed on the top surface of the upper housing cover 50 or on the side wall of the compressor subunit 10. Furthermore, in the compressor subsystem located in the middle or at the bottom along the axial direction X of the compressor subunit 10, the exhaust unit 30 is disposed on the side wall of the compressor subunit 10. It should be noted that the exhaust unit 30 is used to transport the compressed gas in the compressor to the downstream process system through a pipeline. The position of the exhaust unit 30 in different types of compressors is also different. Usually, in a centrifugal compressor, the exhaust unit 30 is arranged on the side of the body, and in a screw compressor, the exhaust unit 30 is arranged on the top of the body. In this embodiment, since each compressor subsystem needs to independently control an external system, each compressor subsystem needs to be configured with an exhaust unit 30. Taking into account the differences in occupied space and installation position, the exhaust unit 30 in the top compressor subsystem can be arranged on the side wall or top surface of the compressor subunit 10, while the exhaust units 30 in the middle and bottom compressor subsystems are all arranged on the side wall of the compressor subunit 10.

[0039] Furthermore, the compressor subsystem also includes a power module interface 60. In the compressor subsystem located at the top along the axial direction X of the compressor subunit 10, the power module interface 60 is disposed on the top surface of the upper shell cover 50 or on the side wall of the compressor subunit 10. In the compressor subsystem located in the middle or at the bottom along the axial direction X of the compressor subunit 10, the power module interface 60 is disposed on the side wall of the compressor subunit 10. It should be noted that, to further meet the independent control requirements of each compressor subsystem, a power module interface should be provided in each compressor subsystem, and a power source should be connected to the power module interface 60 to provide power to the compressor subunit 10. Of course, in some optional embodiments, those skilled in the art may also configure more different functional modules in the compressor subsystem according to actual needs to accommodate compressor subunits 10 with different functions.

[0040] As an optional embodiment, the first connecting portion is welded to the bottom surface of the paired compressor subunit 10; the second connecting portion is welded to the top surface of the compressor subunit 10 in another compressor subsystem; when the compressor includes a foot 40, the foot 40 is welded to the compressor subsystem; when the compressor includes an upper shell cover 50, the upper shell cover 50 is welded to the compressor subsystem. In other embodiments, the connection relationship between the first connecting portion and the bottom surface of the paired compressor subunit 10, the second connecting portion and the top surface of the compressor subunit 10 of another compressor subsystem, the foot 40 and the compressor subsystem, and the upper shell cover 50 and the compressor subsystem can also be other fixed connection methods. Those skilled in the art can configure this according to actual conditions, and this embodiment is not limited to this.

[0041] To achieve the above-mentioned purpose, the present invention also provides a temperature control device, including the compressor described above. As some optional embodiments, temperature control devices using the above-mentioned compressor, such as air conditioning systems, can achieve independent temperature and humidity control, with one compressor subsystem controlling the temperature and another compressor subsystem controlling the humidity, eliminating the need for electric heating after dehumidification to reach the required temperature. Multi-stage compression can also be achieved by using the above-mentioned compressor to meet the requirements of use under harsh working conditions. At the same time, multiple independent systems can more flexibly control the temperature within a limited space, effectively improving the user experience and having a wide range of application scenarios.

[0042] In summary, in the compressor and temperature control device provided in the embodiments of the present invention, the compressor includes: at least two compressor subsystems; the compressor subsystem includes paired compressor subunits and a liquid reservoir, and the compressor subunit is connected to the compressor subunit in another compressor subsystem through the liquid reservoir; the compressor subsystems operate independently of each other; at the same time, the liquid reservoir has a connecting end and an air inlet end, the connecting end is connected to the paired compressor subunit, and the air inlet end is used to connect to an external system; different compressor subsystems are respectively connected to different external systems through paired liquid reservoirs to achieve control of different external systems.

[0043] So configured, the compressor provided by the present application includes multiple compressor subsystems, each of which includes a compressor subunit and a liquid reservoir. The liquid reservoir is used to connect the compressor subunits located in the two compressor subsystems. At the same time, the liquid reservoir is used to connect the compressor subunit and the external system. Different compressor subsystems work independently of each other. Therefore, the compressor provided by the present application is no longer limited to controlling the operation of only one specific system. It can select compressor subsystems of different specifications and different refrigerants according to needs, and can also control any system to work, or control multiple different systems to work at the same time, further broadening the application scenarios of the compressor; in addition, compared with the existing compressor that sets the liquid reservoir on the side wall of the shell, the liquid reservoir is used as the connecting part between the two compressor subsystems, which makes the liquid reservoir more solid and saves a certain amount of assembly space, and can be applied to more application scenarios.

[0044] Furthermore, the temperature control device provided in this application uses the compressor as described above, so that the temperature control device can realize independent control of multiple functions, optimize the use of the temperature control device and the user experience. At the same time, multiple compressor subsystems can also realize multi-stage compression, which can meet the use under harsh working conditions, further broadening the application scenarios of the temperature control device.
