Technical Field
[0001] This application relates to a pneumatic system, and more particularly to an integrated pneumatic system for a vehicle. Background Art
[0002] Currently, air suspension systems are mainly used to improve the comfort and handling of vehicles and usually include an independent compressor and a control unit to adjust the suspension stiffness. However, an independent compressor system means higher costs and complexity. A thermostatic device, as a luxury accessory, usually also uses an independent compressor and has a different compressor medium from that of the air suspension. This results in increased costs and difficult maintenance. Under certain working conditions, the performance of the automotive air conditioner may be insufficient, especially in extreme weather conditions or when fully loaded.
[0003] At the same time, the increase in electronic devices in vehicles has made the EMC problem more severe. Also, noise problems, especially the vibration and noise caused by the compressor, have a negative impact on passenger comfort and the overall vehicle performance. Integrating these independent modules effectively into the vehicle design is a challenge within the framework of the prior art.

Heat exchange may not occur between the first water-cooled condenser heat pipe and the third water-cooled condenser heat pipe.
[0031] It should be noted that in the dual-channel air-conditioning evaporator 54 of the air-conditioning device 1, the first inlet end 54i1 is connected to the first outlet end 54e1 via the first evaporator heat pipe, and the second inlet end 54i2 is connected to the second outlet end 54e2 via the second evaporator heat pipe.

[0035] The integrated pneumatic system according to the present application includes a refrigeration mode and a hybrid mode.
[0036] In the refrigeration mode, the first solenoid valve 53, the second solenoid valve 60, the third solenoid valve 61, the fifth solenoid valve 70 and the first electronic expansion valve 71 are opened. The fourth solenoid valve 64 is optionally opened. The first port 52a and the third port 52c of the first three-way valve 52 are opened, and the second port 52b is closed. The first port 57a and the second port 57b of the second three-way valve 57 are opened, and the third port 57c is closed. The first port 59a, the second port 59b and the third port 59c of the third three-way valve 59 are opened. The heat exchange medium (such as carbon dioxide) is compressed in the air-conditioning compressor 50, enters the dual-channel water-cooled condenser 51 for heat exchange (heat release), enters the dual-channel air-conditioning evaporator 54 via the first three-way valve 52 and the first solenoid valve 53 for heat exchange (heat absorption), and finally returns to the air-conditioning compressor 50. When the air-conditioning compressor 50 starts, the first pump 55 starts to pump the coolant into the dual-channel water-cooled condenser 51. The coolant exchanges heat (absorbs heat) in the dual-channel water-cooled condenser 51, enters the radiator 56 via the second three-way valve 57 for heat exchange (releases heat), and finally returns to the first pump 55. The heat exchange medium (such as carbon dioxide) is compressed in the thermostat compressor 58, enters the dual-channel water-cooled condenser 51 for heat exchange (heat release). The heat exchange medium from the thermostat compressor 58 is divided into three parts. The first part of the heat exchange medium enters the dual-channel air-conditioning evaporator 54 via the third three-way valve 59 and the second solenoid valve 60 for heat exchange (heat absorption), and finally returns to the thermostat compressor 58. The second part of the heat exchange medium enters the thermostat evaporator 62 via the third three-way valve 59 and the third solenoid valve 61 for heat exchange (heat absorption), and finally returns to the thermostat compressor 58. The third part of the heat exchange medium enters the dual-channel low-temperature condenser 66 via the third three-way valve 59 and the first electronic expansion valve 71 for heat exchange (heat absorption), optionally enters the air spring 63 via the fourth solenoid valve 64, and finally returns to the thermostat compressor 58.
[0037] In other words, in the refrigeration mode, the heat exchange medium in the air-conditioning device 1 cools at the air-conditioning evaporator 54. The heat exchange medium in the thermostat device 2 is divided into three parts. The first part of the heat exchange medium assists in refrigeration in the air-conditioning device 1, the second part of the heat exchange medium cools in the thermostat device 2, and the third part of the heat exchange medium does work in the air suspension 3 to operate the inflation and deflation of the air suspension 3 and adjust the height of the vehicle.
[0038] In the hybrid mode, the first solenoid valve 53 and the second solenoid valve 60 are closed. The third solenoid valve 61, the fifth solenoid valve 70, and the second electronic expansion valve 72 are open. The first port 52a and the second port 52b of the first three-way valve 52 are open, and the third port 52c is closed. The first port 57a and the third port 57c of the second three-way valve 57 are open, and the second port 57b is closed. The first port 59a and the third port 59c of the third three-way valve 59 are open, and the second port 59b is closed. The heat exchange medium is compressed in the air-conditioning compressor 50, enters the dual-channel water-cooled condenser 51 for heat exchange (heat release), passes through the first three-way valve 52 and the second electronic expansion valve 72, enters the dual-channel low-temperature condenser 66 for heat exchange (heat absorption), and finally returns to the air-conditioning compressor 50. When the air-conditioning compressor 50 starts, the first pump 55 starts to pump the coolant into the dual-channel water-cooled condenser 51. The coolant exchanges heat (absorbs heat) in the dual-channel water-cooled condenser 51, passes through the second three-way valve 57, enters the air-conditioning heat exchanger 69 for heat exchange (releases heat), and finally returns to the first pump 55. The heat exchange medium is compressed in the thermostatic equipment compressor 58, enters the dual-channel water-cooled condenser 51 for heat exchange (heat release). The heat exchange medium from the thermostatic equipment compressor 58 is divided into two parts. The first part of the heat exchange medium passes through the third three-way valve 59 and the third solenoid valve 61, enters the thermostatic equipment evaporator 62 for heat exchange (absorbs heat), and finally returns to the thermostatic equipment compressor 58. The second part of the heat exchange medium passes through the third three-way valve 59 and the first electronic expansion valve 71, enters the dual-channel low-temperature condenser 66 for heat exchange (absorbs heat), optionally passes through the fourth solenoid valve 64 to enter the air spring 63, and finally returns to the thermostatic equipment compressor 58. When the air-conditioning compressor 50 starts, the second pump 68 starts to pump the coolant into the dual-channel low-temperature condenser 66. The coolant exchanges heat (releases heat) in the dual-channel low-temperature condenser 66, enters the heat exchanger 67 for heat exchange (absorbs heat), and finally returns to the second pump 68.
[0039] In other words, in the hybrid mode, the coolant in the air-conditioning device 1 is heated at the air-conditioning heat exchanger 69. The heat exchange medium in the thermostatic equipment 2 is divided into two parts. The first part of the heat exchange medium assists in heating in the air-conditioning device 1 (transfers heat to the coolant in the air-conditioning device 1) and optionally does work in the air suspension 3, and the second part of the heat exchange medium is used for refrigeration in the thermostatic equipment 2.
[0040] It should be noted that in the integrated pneumatic system for vehicles according to the present application, the priority of the air suspension 3 is higher than that of the thermostatic equipment 2, that is, the pressure in the air suspension 3 should be preferentially ensured to be within the normal range.

[0053] In summary, the thermostatic equipment and the auxiliary air - conditioner can use carbon dioxide as the heat - exchange medium, and the air suspension can also use carbon dioxide as the working medium. Since the air pressure required by the thermostatic equipment is significantly higher than that of the air suspension and there is an adequate air source, borrowing the heat - exchange medium of the thermostatic equipment as the working medium can start the air suspension faster without waiting for the compressor to inflate the air suspension separately. In addition, during the idle time of the air suspension and the thermostatic equipment, the thermostatic equipment can also assist the air - conditioning equipment in heat exchange.
