[0032] Specific implementation method
[0033] Hereinafter, one or more implementations will be described in detail with reference to the accompanying drawings. Regardless of the reference numerals, the same or similar constituent elements are assigned the same reference numerals, and repeated descriptions thereof will be omitted.
[0034] In some implementations, the controller may include: a communication device configured to communicate with another control unit or a sensor to control a corresponding function; a non-volatile memory configured to store an operating system, logic instructions, and input / output information; and one or more processors configured to perform determinations, calculations, decisions, etc. to control the corresponding functions.
[0035] Hereinafter, an air conditioning system for a travel vehicle according to an exemplary implementation of the present disclosure will be described with reference to the accompanying drawings.
[0036] In some implementations, such as Figures 1 to 7 As shown, an air conditioning system for a travel vehicle may include: a shell 100, which is installed on the upper side or the lower side of the travel vehicle and has an air inlet 110 and an exhaust port 120, and the air inlet 110 extends along the edge of the shell 100; a heat exchange unit 200, which is arranged in the shell 100; a door 300, which is installed on the shell 100 and is configured to be movable upward or downward and to open or close the air inlet 110 according to the moving position; a drive unit 400, which is installed in the shell 100 and connected to the door 300, and the drive unit is configured to adjust the position of the door 300 in the up and down directions; and a controller 500, which is configured to control the drive unit 400 based on a preset logic for each situation.
[0037] The housing 100 may be installed on an upper side of a travel vehicle and constitute a roof-type air conditioning system.
[0038] The housing 100 has an air inlet 110 through which air is introduced, and an air outlet 120 through which the air introduced into the housing 100 is exhausted.
[0039] In particular, the air conditioning system of the present disclosure is configured so that air can be introduced into the housing 100 even in any direction of the traveling vehicle (such as the forward / reverse direction and the left / right direction of the traveling vehicle). The air inlet 110 extends along the edge of the housing 100. Therefore, air can be introduced into the housing 100 through the air inlet 110 in the forward, left, right and rearward directions of the traveling vehicle, so that air can be introduced into the housing 100 regardless of the traveling direction of the traveling vehicle.
[0040] In some examples, the housing 100 also has a space in which the internal air flows in a separate manner from the external air flow. An HVAC including a fan device and an internal heat exchanger may also be disposed in the space.
[0041] The heat exchange unit 200 may be disposed in the housing 100 and include a heat exchanger 210 and a fan 220. The heat exchanger 210 may be an external heat exchanger and configured to circulate the refrigerant. The fan 220 may be configured to forcibly blow air. The heat exchanger 210 may exchange heat with the external air flowing in the housing 100 and may be combined with a refrigerant circulation component disposed in the refrigerant circuit to realize a heat pump.
[0042] In some examples, the door 300 is mounted on the housing 100 and configured to open or close the air inlet 110. The door 300 is mounted on the housing 100 and configured to be movable upward or downward so that the door 300 can open or close the air inlet 110. The door 300 may be provided in the form of a frame extending along the inner periphery of the housing 100. Therefore, the door 300 opens the air inlet 110 by moving upward and closes the air inlet 110 by moving downward. The door 300 may have an empty space formed therein so as to avoid interference with other components including the heat exchange unit 200.
[0043] The opening / closing operation of the door 300 may be performed by a driving unit 400 provided in the housing 100 .
[0044] The driving unit 400 is installed in the housing 100 and connected to the door 300. In addition, the driving unit 400 is an operational structure that generates a driving force for adjusting the position of the door 300. Various power transmission structures such as a gear connection structure and an actuator connection structure may be adopted.
[0045] Therefore, the controller 500 may control the driving unit 400 and determine the amount of external air to be introduced into the housing 100 based on the open / closed position of the door 300 .
[0046] That is, control logic according to situations such as driving speed, driving direction, and whether a heat pump is used may be set in the controller 500, and the controller 500 may adjust and open or close the door 300 according to the situation. Therefore, the controller 500 may optimally manage the temperature of the heat exchanger 210 by changing the amount of outside air introduced through the air inlet 110 according to the corresponding situation.
[0047] The air inlet 110 may be provided in a side portion of the housing 100 , the air outlet 120 may be provided in an upper portion or a lower portion of the housing 100 , and the heat exchange unit 200 may be provided such that air flowing from the air inlet 110 to the air outlet 120 passes through the heat exchange unit 200 .
[0048] Since the air inlet 110 is provided in the side portion of the housing 100 as described above, the amount of external air introduced through the air inlet 110 can be ensured when the vehicle is traveling. In addition, since the exhaust port 120 is provided in the upper portion or the lower portion of the housing 100, the external air introduced through the air inlet 110 moves toward the exhaust port 120, so that the flow of the external air is stable.
[0049] In addition, the air inlet 110 and the exhaust port 120 are arranged in the housing 100 while having a height deviation in the up and down directions, and the heat exchange unit 200 is arranged between the air inlet 110 and the exhaust port 120 so that external air flowing from the air inlet 110 to the exhaust port 120 can pass through the heat exchange unit 200.
[0050] In some instances, such as Figures 6 to 8 As shown, the driving unit 400 may include: a driving motor 410, which is installed in the shell 100 and is configured to generate a driving force; and a movable member 420, which is connected to the driving motor 410 and the door 300 and is configured to allow the door 300 to move in the up and down directions while moving in the up and down directions when the driving force is input by the driving motor 410.
[0051] The driving unit 400 includes a driving motor 410 and a movable member 420. The movable member 420 moves the door 300 in the up and down directions while being moved by receiving the driving force of the driving motor 410.
[0052] The driving motor 410 may be installed in the housing 100 and positioned outside the door 300 together with the movable member 420. The driving motor 410 may be provided as a plurality of driving motors 410 to more secure a driving force for moving the position of the door 300.
[0053] The movable member 420 is connected to the door 300. When power is transmitted by the driving motor 410, the movable member 420 enables the door 300 to move in the up and down directions.
[0054] Specifically, the driving motor 410 may be configured to generate a rotational force. The movable member 420 may extend through the interior of the door 300 and be connected to the driving motor 410. The gears 421 may be respectively disposed at one end and the other end of the movable member 420. The engaging end 310 engaged with the gear 421 may be disposed on the door 300.
[0055] That is, the driving motor 410 and the movable member 420 are connected to each other through a gear structure. When the driving motor 410 generates a rotation force, the movable member 420 receives the rotation force and moves linearly in the up-down direction, so that the position of the door 300 can be adjusted in the up-down direction.
[0056] In this case, the movable member 420 extends through the interior of the door 300, so that the door 300 can be kept connected to the movable member 420 in a balanced manner, and when the movable member 420 moves, the door 300 can be stably moved in the up and down directions without being biased toward any side.
[0057] The movable member 420 may be formed in a rod shape, and the door 300 may have a guide slot 320 into which the movable member 420 is inserted.
[0058] Furthermore, the movable member 420 extends through the portion having a smaller width and is disposed inside the door 300, so that the length of the movable member 420 can be reduced, thereby ensuring the rigidity of the movable member and reducing the manufacturing cost.
[0059] As described above, the movable member 420 may be formed in a rod shape and extend through the inside of the door 300. In this case, the door 300 may have a guide slot 320 extending upward from the lower end of the door 300, and the movable member 420 may be inserted into the guide slot 320. Specifically, the guide slot 320 may be shaped so that when the door 300 moves downward and closes the air inlet 110, the movable member 420 is located at the uppermost end of the guide slot 320, and when the door 300 moves upward and opens the air inlet 110, the movable member 420 is located at the lowermost end of the guide slot 320.
[0060] Therefore, when the door 300 moves linearly in the up-down direction with the rotation of the movable member 420, the movable member 420 remains inserted into the guide slot 320, so that the upward and downward movement of the door 300 is guided in the extending direction of the guide slot 320, and the tilting movement of the door 300 is prevented. Therefore, the supporting force is ensured in the state where the air inlet 110 is closed.
[0061] In addition, gears 421 are respectively provided at one end and the other end of the movable member 420, and an engaging end portion 310 engaged with the gear 421 is provided on the door 300. When the movable member 420 rotates with the operation of the driving motor 410, the gear 421 rotates and moves in the up-down direction along the engaging end portion 310 in a state where the gear 421 is engaged with the engaging end portion 310.
[0062] Specifically, the rack 311 may be provided on the engaging end portion 310 of the door 300 in the up-down direction, and the gears 421 respectively provided at one end and the other end of the movable member 420 may be engaged with the rack 311 , respectively.
[0063] For example, Figure 8As shown, the rack 311 is provided on the engagement end portion 310 in the up-down direction, and a gear protrusion engaged with the rack 311 is formed on the outer peripheral surface of the movable member 420. When the gear 421 rotates together with the movable member 420, the engagement end portion 310 moves linearly in the up-down direction by the rotational movement of the gear 421. Therefore, the door 300 can open or close the air inlet 110 by moving upward or downward with the operation of the driving unit 400.
[0064] In some implementations, as a detailed structure of the driving unit 400, the driving motor 410 has a piston configured to move linearly upward or downward, and the movable member 420 moves upward or downward as the piston moves. Various implementations can be applied to adjust the position of the door 300 in the up and down directions by the driving unit 400.
[0065] In some instances, such as from Figure 5 and Figure 6 It can be seen that a plurality of support members 130 may be disposed in the housing 100 and pass through the air inlet 110 in the up-down direction. The respective support members 130 may be disposed to be spaced apart from each other by a predetermined interval.
[0066] Since the air inlet 110 extends along the edge of the side portion of the housing 100, spaces spaced apart from each other are defined in the up-down direction in the housing 100. Therefore, a support member 130 passing through the air inlet 110 in the up-down direction may be provided in the housing 100 and reinforce the rigidity of the vacant space defined by the air inlet 110, thereby ensuring the overall rigidity of the housing 100. The support members 130 may be provided in the air inlet 110 and spaced apart from each other by a predetermined interval. The number of the support members 130 or the thickness of the support members 130 may be determined according to the rigidity of the housing 100 and the amount of external air introduced through the air inlet 110.
[0067] In addition, if Figure 7 It can be seen that the first rib 330 may be formed inside the edge of the door 300 , and the second rib 340 may extend along the edge of the outer surface or the inner surface of the door 300 .
[0068] The door 300 may be configured to withstand wind caused by the vehicle when the vehicle is traveling. Specifically, since the door 300 of the present disclosure may be applied to a vehicle that can travel in multiple directions including forward, backward, leftward, and rightward directions, the overall rigidity of the door 300 may be ensured.
[0069] Therefore, the first rib 330 may be formed inside the edge of the door 300, and the second rib 340 may be formed along the edge of the outer surface of the door 300, thereby preventing bending deformation and ensuring rigidity. Therefore, when the door 300 is positioned to close the air inlet 110, the air inlet 110 can be maintained in a closed state even when the traveling vehicle travels at high speed.
[0070] In some examples, the controller 500 may be configured to: Fig. 9 Steps S1 to S6 of the flowchart shown in FIG. 1 adjust the position of the door 300 by controlling the drive unit 400 for each case.
[0071] In a case where the travel speed of the traveling vehicle is a preset speed or higher, the controller 500 may control the driving unit 400 to open the door 300 .
[0072] In this case, it is determined whether the traveling vehicle is traveling at a high speed by setting a preset speed. When the controller 500 determines that the traveling vehicle's traveling speed is a preset speed or higher and the traveling vehicle is traveling at a high speed, the controller 500 determines whether to open the door 300. The air inlet 110 may be formed to introduce air regardless of the traveling direction of the traveling vehicle. Therefore, when the traveling vehicle's traveling speed is a preset speed or higher, the air inlet 110 is opened so that external air is introduced into the housing 100 through the air inlet 110.
[0073] As described above, when the door 300 is opened when the traveling speed of the traveling vehicle is a preset speed or higher, wind caused by the vehicle may be introduced into the housing 100 so that the outside air may exchange heat with the heat exchange unit 200 .
[0074] In addition, when the traveling vehicle further accelerates in a state where the travel speed is a preset speed or higher, the controller 500 gradually decreases the opening degree of the door 300. When the traveling vehicle decelerates, the controller 500 gradually increases the opening degree of the door 300.
[0075] That is, when the traveling vehicle further accelerates in a state where the traveling speed is a preset speed or higher, the opening degree of the door 300 is gradually reduced according to the traveling speed. Therefore, when the traveling vehicle travels at a high speed, the heat exchanger 210 can be prevented from being overcooled due to an excessive increase in the amount of external air introduced into the housing 100, and the resistance caused by the wind caused by the vehicle can be reduced, so that the driving stability can be ensured.
[0076] In addition, when the travel speed of the traveling vehicle gradually decreases, the amount of external air introduced into the housing 100 also decreases to the extent corresponding to the decrease in the travel speed. Therefore, the opening degree of the door 300 can be gradually increased.
[0077] In some examples, the controller 500 may control the driving unit 400 to adjust the opening degree of the door 300 according to the heat exchange amount of the heat exchanger 210 .
[0078] In some implementations, the heat exchange unit 200 includes a heat exchanger 210 in which a refrigerant circulates, and the heat exchange unit 200 allows external air to exchange heat with the refrigerant flowing through the heat exchanger 210. Therefore, the temperature of the refrigerant flowing through the heat exchanger 210 can be adjusted based on the amount of external air introduced into the housing 100 through the air inlet 110.
[0079] The heat pump may be implemented by the heat exchanger 210. Based on the temperature condition of the refrigerant passing through the heat exchanger 210, the amount of heat exchange between the heat exchanger 210 and the outside air introduced into the housing 100 may be adjusted by adjusting the opening degree of the door 300. Therefore, when various modes including the heat pump are implemented by circulating the refrigerant, the temperature of the refrigerant may be managed by the heat exchanger 210.
[0080] In some examples, the controller 500 may control the driving unit 400 to open the door 300 when performing a cleaning mode for removing foreign substances in the housing 100 .
[0081] The cleaning mode can be used to remove foreign matter in the housing 100 and is specifically performed to prevent dust accumulation. The cleaning mode can be performed by a command input by a user, automatically when a predetermined time has passed, or based on the detected amount of dust accumulated in the housing 100.
[0082] The cleaning mode allows the door 300 to be opened. In the present disclosure, since the external air introduced through the air inlet 110 forms an air flow to be exhausted through the air outlet 120, dust may be inadvertently introduced and accumulated in a portion of the space in the housing 100.
[0083] Therefore, when the cleaning mode is executed, as the door 300 is opened, the air inlet 110 is opened, so that when external air is introduced into the air inlet 110 and then discharged, dust can be discharged to the outside. That is, the dust in the housing 100 is discharged to the outside by the air flow introduced through the air inlet 110 and then discharged from the air inlet 110, rather than being discharged to the outside by the external air flow flowing from the air inlet 110 to the exhaust port 120.
[0084] In addition, when the travel vehicle is traveling, the controller 500 may execute the cleaning mode, and the controller 500 may control the fan 220 so that the fan 220 does not operate.
[0085] That is, the heat exchange unit 200 includes a fan 220 configured to allow the air in the heat exchanger 210 and the housing 100 to pass through the heat exchanger 210 and then be discharged through the exhaust port 120. In this case, an external air flow flowing through the air inlet 110 can be formed when the cleaning mode is performed. Therefore, the fan 220 is not operated so that the external air does not flow toward the exhaust port 120. Thus, when the cleaning mode is performed, the external air flows through the air inlet 110 so that foreign matter in the housing 100 can be smoothly removed by the wind caused by the vehicle.
[0086] In this case, after a preset predetermined time period has passed while the cleaning mode is being performed, the controller 500 may control the driving unit 400 to adjust the operation of opening or closing the door 300 according to the logic of each previous situation.
[0087] In the cleaning mode, the door 300 is fully opened so that the amount of outside air flowing toward the heat exchanger 210 can be reduced. Therefore, after a preset predetermined time has passed while the cleaning mode is being performed, the operation of opening or closing the door 300 is adjusted according to the logic of each previous situation, thereby ensuring the heat exchange amount of the heat exchanger 210. The predetermined time can be set to a time that can sufficiently remove foreign matter in the housing 100 by vehicle introduction wind generated by traveling vehicles.
[0088] According to the air conditioning system for a traveling vehicle constructed as described above, air can be introduced into the housing 100 in which the heat exchanger 210 is built in multiple directions including forward, backward, leftward, and rightward directions. Therefore, external air can be introduced into the heat exchanger 210 and heat exchange can be performed regardless of the traveling direction of the traveling vehicle. In addition, the amount of external air provided to the external heat exchanger 210 is adjusted according to the traveling direction of the traveling vehicle or whether a heat pump is used, which improves the operating efficiency of the external heat exchanger 210.
[0089] Although specific implementations of the present disclosure have been shown and described, it will be apparent to those skilled in the art that various changes and modifications may be made to the present disclosure without departing from the technical spirit of the present disclosure as defined in the appended claims.
