Description

Technical Field

[0001] The present invention belongs to the technical field of vehicle air conditioning, and more specifically, relates to a dual-mode drive parking air conditioning system and a refrigeration method for a military fuel vehicle. Background Art

[0002] With the development of information warfare, the use environment of military vehicles in actual combat has become increasingly complex. In these environments, the vehicle's information equipment needs to remain in combat readiness for a long time, and needs to continue to operate even when the vehicle is turned off. Conventional fuel vehicle air-conditioning systems are mainly used to provide cooling during vehicle driving, relying on the operation of the engine to drive the air-conditioning compressor to rotate, which requires the engine to run. When the vehicle is turned off or parked, in order to use the air-conditioning system, the engine must be kept idling, which not only consumes a lot of fuel and increases costs, but may also cause damage to the engine and shorten its service life. In addition, long-term idling will generate a lot of heat, causing the temperature inside the vehicle to rise, which may trigger the overheating protection mechanism, affecting the normal operation of the equipment and the combat effectiveness of the vehicle. In order to solve this problem, the dual-mode air-conditioning system came into being.

[0003] As shown in the patent document with application number CN202110763140.4, the invention patent discloses a dual-mode parking air conditioning system, which includes a mechanical compressor, an electric compressor and an evaporator. The mechanical compressor is driven by an engine, and the electric compressor is driven by a power supply; a low-pressure transition port of the electric compressor is provided on the cylinder body of the electric compressor, and the low-pressure transition port of the electric compressor is connected to the mechanical compressor suction port of the mechanical compressor through a low-pressure pipeline, and the outlet of the evaporator is connected to the electric compressor suction port of the electric compressor through the evaporator to the compressor low-pressure pipeline. In the dual-mode parking air conditioning system of the present invention, when the mechanical compressor is running, the refrigeration oil will return to the mechanical compressor through the cavity of the electric compressor, and the electric compressor can retain a certain amount of refrigeration oil; when the electric compressor is switched to run, the amount of oil stored inside itself can also meet the lubrication requirements for a certain period of time, so that the purpose of reasonable distribution of refrigeration oil in the dual-mode parking air conditioning system can be achieved, so that the entire air conditioning system can operate normally in driving and parking modes, meeting the cooling requirements of the cockpit. However, this invention adds a parallel electric compressor on the basis of the original mechanical drive compressor. Although it is possible to switch to the electric compressor to provide cooling when parking, this solution requires adding an additional electric compressor in the engine compartment, resulting in space constraints and the risk of compressor lubricating oil returning, which may shorten the service life of the compressor. Another example is the patent document with application number CN202011642142.X, which discloses an integrated dual-mode air conditioner for mining vehicles, including a driving compressor, a first oil separator, a first one-way valve, a condenser, a liquid reservoir, an expansion valve, an evaporator and a first gas-liquid separator connected in series in sequence to form a driving air conditioning refrigerant circuit, which is responsible for air conditioning refrigeration during driving; a first parking electric compressor connected in series with a second oil separator is connected in parallel with a second parking electric compressor connected in series with a third oil separator, and then connected in series with a second one-way valve, a condenser, a liquid reservoir, an expansion valve, an evaporator and a second gas-liquid separator to form a parking air conditioning refrigerant circuit, which is responsible for air conditioning refrigeration in the parking state; the air conditioning refrigeration mode can realize independent operation of the driving and parking dual circuits and automatic switching; the integrated controller can realize integrated control of heating and cooling, driving and parking. This invention requires the addition of additional components such as compressors and separators, which not only increases the weight of the vehicle, but also takes up a lot of space, which is not conducive to the mobility and concealment of military vehicles.

[0036] In the present invention patent, the term "includes", "comprising" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of more restrictions, the elements defined by the sentence "comprising..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0037] like Figure 1-2 As shown, an embodiment of the present invention provides a dual-mode drive parking air conditioning system for military fuel vehicles, including a compressor and bracket module, a condensation and heat dissipation module, an evaporator and pipeline module, a power supply and wiring harness module, and a liquid storage module. The compressor and bracket module, as the core power source of the air conditioning system, is connected to the condensation and heat dissipation module and the evaporator and pipeline module through pipelines to form a refrigerant circulation loop. The compressor and bracket module are also electrically connected to the power supply and wiring harness module through a wiring harness to receive electric energy to drive the work. Through the organic combination of the five modules, when the vehicle is in a driving state, the engine drives the compressor to rotate through a transmission belt. When the vehicle is in a parking state, the power supply and wiring harness module provides electric energy to the compressor, and the compressor starts to work, compressing the refrigerant into a high-temperature and high-pressure gas and discharging it. The high-temperature and high-pressure gas enters the condensation and heat dissipation module, exchanges heat with the external environment through the condenser, cools and liquefies into a liquid refrigerant. The liquid refrigerant then enters the evaporator and pipeline module through the pipeline, evaporates into a gaseous state in the evaporator, and absorbs the heat in the vehicle to achieve a cooling effect. The evaporated refrigerant returns to the compressor through the pipeline again to complete a cycle. The liquid storage module regulates and stores refrigerant during the entire cycle to ensure stable operation of the system.

[0038] in,

[0039] The compressor and bracket module includes a dual-mode integrated compressor 1, an integrated compressor bracket 12 and a transmission belt 3. The dual-mode integrated compressor 1, as the core component of the system, can be compatible with two working modes: power taken from the chassis power belt when driving and power supplied by the mains when parking. The integrated compressor bracket 12 fixes the dual-mode integrated compressor 1 to ensure its stable operation. The bracket design needs to consider factors such as the weight, vibration and installation space of the compressor;

[0040] like Figure 5 As shown, the dual-mode integrated compressor 1 includes a clutch 101, a pulley 102, a motor 103, a motor rotor 104, a stator 105, an electric drive controller 106, a housing 107 and a scroll plate 108. When the engine is driven, the clutch 101 has an energizing voltage of 24V, and the electric drive controller 106 is not powered and is in a disconnected state; when the vehicle is parked, the electric drive controller 106 works, and the driving plate of the clutch 101 is in a non-engaged state; when the electric drive mode is adopted, the electric drive controller 106 converts the AC220V mains power into a power supply voltage of DC300V to drive the dual-mode integrated compressor 1 to work, and the clutch 101 is automatically disengaged at this time, and the scroll plate 108 compresses air at high speed, and the air conditioner starts to work;

[0041] Furthermore, if Figure 2 As shown, the transmission belt 3 connects the pulley of the engine and the pulley 102 of the dual-mode integrated compressor 1, so that the compressor is driven by the chassis power when driving. In the driving mode, the engine drives the dual-mode integrated compressor 1 to rotate through the transmission belt 3, and the dual-mode integrated compressor 1 starts to work, compresses the refrigerant and sends it into the system circulation.

[0042] The condensation heat dissipation module includes a condensation fan fixing bracket 7, a condensation fan 8, an air conditioning condenser 6 and a front camera bracket 5;

[0043] The condensing fan fixing bracket 7 fixes the condensing fan 8 to ensure its stable position. When the compressor is working, the refrigerant in the air-conditioning condenser 6 releases heat, and the condensing fan 8 accelerates the air flow to help the refrigerant to dissipate heat quickly and maintain the normal operation of the system. When parking, the condensing fan can also continue to work to facilitate the heat dissipation of the air-conditioning condenser 6 when the vehicle is turned off. The related wiring harness of the condensing fan 8 is fixed by using the existing front camera bracket 5 of the vehicle to save space and simplify wiring.

[0044] like Figure 1-3 The evaporator and pipeline module includes an evaporator, a low-pressure air intake air conditioning pipe 17, a high-pressure exhaust air conditioning pipe 18, a pipeline fixing bracket 19, a pipeline sealing protection plate 20, an air pipe fixing bracket 2, an air straight pipe 13 and an air elbow 14;

[0045] The evaporator includes a front evaporator 26, which is used to evaporate the liquid refrigerant into gaseous state, absorb the heat in the vehicle compartment, and realize cooling. According to the arrangement of the whole vehicle, a branch floor-type evaporator 23 or a top-type evaporator 25 is arranged in the rear compartment of the cab to connect with the front evaporator 26, so as to increase cooling for the rear compartment of the cab;

[0046] One end of the low-pressure air intake air conditioning pipe 17 is connected to the evaporator, and the other end is connected to the dual-mode integrated compressor 1, for conveying low-pressure gaseous refrigerant; one end of the high-pressure exhaust air conditioning pipe 18 is connected to the dual-mode integrated compressor 1, and the other end is connected to the air conditioning condenser 6, for conveying high-temperature and high-pressure gaseous refrigerant; after being compressed in the dual-mode integrated compressor 1, the refrigerant forms a high-temperature and high-pressure refrigerant gas, which is sent to the air conditioning condenser 6 through the high-pressure exhaust air conditioning pipe 18, becomes liquid after condensation, and then passes through the expansion valve to form a low-temperature and low-pressure refrigerant, which enters the evaporator through the low-pressure air intake air conditioning pipe 17. The refrigerant in the evaporator absorbs heat when evaporating, achieving refrigeration;

[0047] The pipeline fixing bracket 19 and the pipeline sealing protection plate 20 are used to fix and protect the low-pressure air intake air conditioning pipe 17 and the high-pressure air exhaust air conditioning pipe 18 to prevent them from being damaged due to vibration or external force;

[0048] The straight air pipe 13 and the curved air pipe 14 are fixedly mounted on the air pipe fixing frame 2 to transmit the processed air.

[0049] like Figure 1 , 2 as well as Figure 4 As shown, the power supply and wiring harness module includes a dual-mode integrated air-conditioning integrated power supply 16, a dual-mode integrated air-conditioning integrated power supply support frame 15, an input aviation plug 4, a front cover mounting bracket 10, a connecting wiring harness 24, a cable sealing protection plate 21 and a fuse box bracket 22.

[0050] The dual-mode integrated air conditioner integrated power supply 16 is supported and fixed by the dual-mode integrated air conditioner integrated power supply support frame 15, which provides power for the dual-mode integrated compressor 1 and supports two power supply modes: driving and parking.

[0051] The front cover mounting bracket 10 is mounted at the front end of the engine compartment, and a hole is opened on the front cover to arrange the input aviation plug 4 for connecting to an external AC power supply to power the air conditioner when the vehicle is parked.

[0052] The connecting harness 24 passes through the floor through the cable sealing protection plate 21 and enters the vehicle compartment, and is fixed in the engine compartment through the fuse box bracket 22. It connects the dual-mode integrated air-conditioning integrated power supply 16 and the dual-mode integrated compressor 1 to transmit power and signals.

[0053] The liquid storage module includes an air-conditioning liquid storage tank 9 and an air-conditioning liquid storage tank bracket 11. The air-conditioning liquid storage tank 9 is fixed by the air-conditioning liquid storage tank bracket 11 and is used to store excess refrigerant to balance the system pressure.

[0054] In summary, the embodiment of the present invention provides a vehicle air-conditioning system solution through a series of designs and optimizations. When driving, the compressor is powered by the chassis power belt; when parked, the AC power enters the air-conditioning controller through the input aviation plug, and is converted into AC320V and then supplied to the compressor, thereby realizing the improvement of the traditional fuel automobile air-conditioning refrigeration system, improving the flexibility and efficiency of the system, and meeting the refrigeration needs during driving and parking.

[0055] like Figure 6 As shown, the present invention provides a refrigeration method for a dual-mode drive parking air conditioning system of a military fuel vehicle, comprising the following steps:

[0056] S100: System startup, detection and mode recognition: When the vehicle is started or the external mains is connected, the dual-mode integrated air conditioner power supply starts to supply power, and the system performs a self-check to detect the working status and connection status of the compressor, condenser, evaporator, fan and other components to ensure that the system is fault-free. The system identifies the current driving mode or parking mode through the vehicle's startup signal or the driver's operation;

[0057] S200: Driving mode control: When the vehicle is in driving mode, the engine is running, the pulley of the dual-mode integrated compressor is driven to rotate through the transmission belt, the clutch is engaged, the electric drive controller is powered off and disconnected, the compressor is driven by the engine power, and the compressor starts to compress the refrigerant and enters the system to realize cooling;

[0058] S300: Parking mode control: When the vehicle is turned off and the engine is not working, the system switches to parking mode, the aviation plug is connected to the mains power, and the AC220V mains power is converted to DC300V through the electric drive controller to supply the compressor. The clutch is automatically disengaged in the electric drive mode, the compressor is driven by the motor, and starts to run under the electric drive, and the air conditioner starts to work;

[0059] S400: System shutdown: When the vehicle is turned off and the AC power is disconnected, the system automatically shuts down and all modules stop working.

[0060] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
