Description

Technical Field

[0001] The present invention relates to an air conditioning system for a vehicle (e.g., a mobile travel device, a mobile travel equipment, a mobile travel instrument), and more particularly to an air conditioning system for a vehicle, wherein a condenser and an evaporator are arranged in a housing to face each other. The air conditioning system according to the present invention can simplify a refrigerant circuit, reduce the length of an air flow path, and reduce heat loss that may be generated when air flows. Background Art

[0002] Generally, the air conditioner is a front air conditioner and is configured to discharge cooling air or heating air from an outlet formed at a dashboard provided at the front side of the vehicle interior. Therefore, in the case where the vehicle interior space is large, the rear seats may not be sufficiently cooled or heated.

[0003] Therefore, in order to assist cooling or heating the rear seats, a rear seat air conditioner or a roof type air conditioner is provided. The rear seat air conditioner or the roof type air conditioner is installed on the roof of the vehicle and is configured to discharge conditioned air from above the head of the occupant.

[0004] Specifically, the roof-type air conditioning device has a heat exchanger configured to perform heat exchange with the outside air. The heat exchanger is also installed on the roof. However, within the limited space of the roof, the amount of outside air that can be provided to the heat exchanger is limited.

[0005] In addition, in recent years, various self-driving vehicles have been developed. The self-driving vehicles can travel in two directions (e.g., left and right) and in forward / reverse directions. However, in the related prior art, external air is introduced into the roof-type air conditioning device through a certain part, which is restrictively set at the front side, so that when the vehicle travels in the left direction, right direction or backward direction, the external air that needs to be provided to the heat exchanger of the roof-type air conditioning device cannot be fully introduced.

[0006] Furthermore, when the heat exchanger is provided to independently perform air conditioning functions for the front seats and the rear seats, the arrangement of the lines is complicated, additional components such as separate valves are required, and the overall size increases, which is disadvantageous in terms of packaging.

[0007] The above description as background is only to help understand the background of the present invention. Therefore, the above content does not mean that the present invention belongs to the scope of the related technology known to ordinary technicians in the field. Summary of the invention

[0008] The present invention is proposed to solve the above-mentioned problems, and aims to provide an air conditioning system for a vehicle, wherein a condenser and an evaporator are arranged in a shell to face each other, which can simplify the refrigerant circuit, reduce the length of the air flow path, and reduce the heat loss that may be generated when the air flows.

The second air conditioning door is disposed at a branch point between an external passage connected to a second air conditioning space and an internal passage, and determines a flow route of air that has passed through the first heat exchange unit.

[0017] The first air outlet path is divided into a plurality of routes in the first air-conditioned space. The second air outlet path is divided into a plurality of routes in the second air-conditioned space. The outer passage of the first air outlet path and the outer passage of the second air outlet path extend in the same direction.

[0018] The housing includes a first duct component connected to an internal passage of a first air outlet path and a second duct component connected to an internal passage of a second air outlet path.

[0045] According to the present invention Figure 1-3As shown, the air conditioning system includes a housing 100 having an inner space S connected to an air inlet path 110 and an air outlet path 120. The air outlet path 120 is divided into an inner channel 121 and an outer channel 122. The air conditioning system further includes: an air conditioning door 200, which is disposed in the housing 100 and is configured to allow air to selectively flow to the inner channel 121 or the outer channel 122; a first heat exchange unit 300, which is disposed in the inner space S of the housing 100; and a second heat exchange unit 400, which is disposed in the inner space S of the housing 100 and is configured to face the first heat exchange unit 300.

[0046] The housing 100 may be mounted on an upper side of a vehicle and constitute a roof type air conditioning system.

[0047] The first heat exchange unit 300 and the second heat exchange unit 400 are disposed in the inner space S of the housing 100 , and are connected to the air inlet path 110 and the air outlet path 120 .

[0048] The first heat exchange unit 300 includes a first heat exchanger 310 and a first blower 320. The second heat exchange unit 400 includes a second heat exchanger 410 and a second blower 420. The first blower 320 and the second blower 420 may operate by receiving a command from a controller.

[0049] In this case, the first heat exchanger 310 may be a condenser, and the second heat exchanger 410 may be an evaporator. The first heat exchanger 310 and the second heat exchanger 410 are connected to a refrigerant circuit. The refrigerant exchanges heat with the air while circulating in the first heat exchanger 310 and the second heat exchanger 410. Therefore, the first heat exchanger 310 generates heating air-conditioning air by heat exchange between the refrigerant and the air, and the second heat exchanger 410 generates cooling air-conditioning air by heat exchange between the refrigerant and the air.

[0050] The refrigerant circuit is provided with a refrigerant circulation assembly A including a compressor, a water-cooled condenser, etc. Figure 1 As shown, the refrigerant cycle assembly A may be installed to be dispersed in different areas of the vehicle.

[0051] As described above, when the first blower 320 of the first heat exchange unit 300 operates, the air introduced through the air inlet path 110 may be heated by heat exchange in the first heat exchanger 310 and then discharged to the inside or outside of the vehicle through the air outlet path 120. In addition, when the second blower 420 of the second heat exchange unit 400 operates, the air introduced through the air inlet path 110 may be cooled by heat exchange in the second heat exchanger 410 and then discharged to the inside or outside of the vehicle through the air outlet path 120.

[0052] In this case, the air outlet path 120 of the housing 100 is divided into an inner passage 121 and an outer passage 122. In addition, the air conditioning door 200 is provided in the housing 100 to enable air to selectively flow to the inner passage 121 or the outer passage 122. The inner / outer air door 500 includes the air conditioning door 200 (to be described below), which can be operated under the control of the controller.

[0053] The heated air having passed through the first heat exchange unit 300 or the cooled air having passed through the second heat exchange unit 400 may be supplied to the vehicle interior or discharged to the outside according to the open or closed position of the air conditioning door 200. The operation of opening and / or closing the air conditioning door 200 may be performed to control the supply of heated air or cooled air to the vehicle interior or discharge to the outside.

[0054] Specifically, in the present invention, the first heat exchange unit 300 and the second heat exchange unit 400 are arranged to face each other in the internal space S, so that the air introduced into the internal space S through the air inlet path 110 of the shell 100 flows to the first heat exchange unit 300 and the second heat exchange unit 400 at the same time and performs heat exchange.

[0055] In addition, the inner passage 121 of the air outlet path 120 in the housing 100 extends and branches from the air outlet path 120 to various areas inside the vehicle. Figure 2 As shown, the inner passage 121 of the air outlet path 120 may extend forward and backward to provide air-conditioned air to the front and rear areas of the vehicle interior. As described above, the air that has been heat-exchanged while passing through the first heat exchange unit 300 and the second heat exchange unit 400 may be discharged to the inside or outside of the vehicle according to the open or closed position of the air-conditioning door 200 provided in the housing 100.

[0056] The present invention will be described in more detail below. Figure 4-8 As shown, the internal space S of the housing 100 includes a flow space S1 and first and second air-conditioned spaces S2 and S3 that are spaced apart from each other based on the flow space S1. The air inlet path 110 may be connected to the flow space S1. The first air outlet path 120a and the second air outlet path 120b may be connected to the first air-conditioned space S2 and the second air-conditioned space S3, respectively.

[0057] In other words, the internal space S of the housing 100 includes a flow space S1, a first air-conditioned space S2, and a second air-conditioned space S3. The first air-conditioned space S2 and the second air-conditioned space S3 are arranged according to the flow space S1. In this case, the first heat exchange unit 300 is disposed in the first air-conditioned space S2, and the second heat exchange unit 400 is disposed in the second air-conditioned space S3, so that the first heat exchange unit 300 and the second heat exchange unit 400 are disposed to face each other based on the flow space S1.

[0058] Therefore, when air enters the flow space S1 through the air inlet path 110 , the air is distributed to the first and second air-conditioned spaces S2 and S3 , so that the air is transferred to both the first and second heat exchange units 300 and 400 .

[0059] The first air outlet path 120a is connected to the first air-conditioning space S2 so that the air having exchanged heat with the first heat exchange unit 300 is discharged to the inside or outside of the vehicle according to an open / closed position of an air-conditioning door 200 provided in the first air outlet path 120a.

[0060] The second air outlet path 120b is connected to the second air-conditioning space S3 so that the air having exchanged heat with the second heat exchange unit 400 is discharged to the inside or outside of the vehicle according to the opening / closing position of the air-conditioning door 200 provided in the second air outlet path 120b.

[0061] The air inlet path 110 is divided into an inside air inlet path 111 and an outside air inlet path 112. An inside / outside air door 500 may be provided in the housing 100 to selectively open or close the inside air inlet path 111 and the outside air inlet path 112.

[0062] The inside air inlet path 111 is connected to the inside of the vehicle, and the outside air inlet path 112 is connected to the outside.

[0063] In the present invention, in the case where the housing 100 is installed on the roof of the vehicle, the air inlet path 110 may be divided into an internal air inlet path 111 and an external air inlet path 112. The internal air inlet path 111 may be provided on the lower surface of the housing 100 and communicate with the interior of the vehicle. The external air inlet path 112 may be provided on the side or upper surface of the housing 100 and communicate with the outside of the vehicle.

[0064] As described above, when the housing 100 is installed on the roof of the vehicle, the internal air inlet path 111 is located below the flow space S1 and minimizes the length of the route connected to the interior of the vehicle. The external air inlet path 112 is located on the side or above the housing 100, which is conducive to introducing external air and preventing interference between components.

[0065] In other words, Figure 4-7 As shown, the outside air inlet path 112 may be formed to be oriented upward or vertically to prevent interference with other components including the heat exchanger unit, and the inside air inlet path 111 may be formed to be oriented downward to provide conditioned air to the interior of the vehicle.

[0066] The internal air inlet path 111 and the external air inlet path 112 are in communication with the flow space S1. The internal / external air door 500 is provided in the flow space S1 so that the amount of internal air introduced and the amount of external air introduced can be controlled. Therefore, according to the opening degree of the internal / external air door 500, a fresh air mode, a recirculation mode, and an internal / external air mixing mode can be performed.

[0067] In the present invention, since the first and second heat exchange units 300 and 400 are disposed in the housing 100, the inside / outside air door 500 includes first and second inside / outside air doors 510 and 520 to selectively provide inside air or outside air to the heat exchange units.

[0068] like Figure 8 As shown, the first inside / outside air door 510 is installed in the flow space S1 of the housing 100 , corresponding to the first heat exchange unit 300 , and adjusts the amount of inside air and / or outside air flowing to the first heat exchange unit 300 .

[0069] In addition, the second inside / outside air door 520 is installed in the flow space S1 of the housing 100 , corresponding to the second heat exchange unit 400 , and adjusts the amount of inside air and / or outside air flowing to the second heat exchange unit 400 .

[0070] For example, refer to Figure 8 , when the first inside / outside air door 510 is opened toward the outside air inlet path 112 in the fresh air mode, outside air introduced through the outside air inlet path 112 may be heat-exchanged while passing through the first heat exchange unit 300 .

[0071] When the second inside / outside air door 520 is located between the inside air inlet path 111 and the outside air inlet path 112 in the inside / outside air mixing mode, the inside air and the outside air mixed through the inside air inlet path 111 and the outside air inlet path 112 may perform heat exchange while passing through the second heat exchanger 410 .

[0072] The first and second inside / outside air doors 510 and 520 may have various shapes, such as a dome door shape and a flap door shape, according to installation positions and installation spaces thereof, positions of the inside air inlet path 111 , and positions of the outside air inlet path 112 .

[0073] Meanwhile, a filter 130 is disposed in the flow space S1 of the housing 100. The filter 130 is configured to remove foreign matter from the air introduced into the flow space S1 through the internal air inlet path 111 and the external air inlet path 112. The filter 130 may be divided into a filter (e.g., a first filter) at a side adjacent to the first heat exchange unit 300 in the flow space S1 and a filter (e.g., a second filter) at a side adjacent to the second heat exchange unit 400. Alternatively, a single filter 130 may also be disposed in the flow space S1.

[0074] Meanwhile, the air-conditioning door 200 includes a first air-conditioning door 210 and a second air-conditioning door 220 .

[0075] like Figure 4 and 9 As shown, the first air-conditioning door 210 is disposed at a branch point between the inner passage 121 and the outer passage 122 connected to the first air-conditioning space S2 , and determines a flow route of air having passed through the first heat exchange unit 300 .

[0076] The second air-conditioning door 220 is disposed at a branch point between the inner passage 121 and the outer passage 122 connected to the second air-conditioning space S3 , and determines a flow route of air having passed through the second heat exchange unit 400 .

[0077] In the present invention, the air outlet path 120 may be divided into forward and backward directions to provide conditioned air to various areas inside the vehicle. The first air conditioning door 210 may be provided as a plurality of first air conditioning doors 210 , and the second air conditioning door 220 may be provided as a plurality of second air conditioning doors 220 .

[0078] Therefore, depending on the opening / closing position of the first air-conditioning door 210, the air that has passed through the first heat exchange unit 300 can flow from the first air outlet path 120a to the internal channel 121, thereby providing heated air to the interior of the vehicle, or the air that has passed through the first heat exchange unit 300 can be discharged to the outside from the first air outlet path 120a through the external channel 122.

[0079] In addition, depending on the opening / closing position of the second air-conditioning door 220, the air that has passed through the second heat exchange unit 400 can flow from the second air outlet path 120b to the internal channel 121, thereby providing cooling air to the interior of the vehicle, or the air that has passed through the second heat exchange unit 400 can be discharged to the outside from the second air outlet path 120b through the external channel 122.

[0080] As described above, the first air conditioning door 210 and the second air conditioning door 220 can selectively provide cold and warm air conditioning to the interior of the vehicle, and the air that exchanges heat with the heat exchange unit and adjusts the refrigerant temperature is discharged to the outside, thereby facilitating the adjustment of the temperature inside the vehicle and the temperature of the refrigerant.

[0081] Meanwhile, the housing 100 may have a first duct member 140 connected to the inner passage 121 of the first air outlet path 120a, and a second duct member 150 connected to the inner passage 121 of the second air outlet path 120b. The first duct member 140 and the second duct member 150 may extend in a plurality of routes to provide conditioned air to different areas in the vehicle interior.

[0082] The first duct member 140 and the second duct member 150 are configured to provide the air-conditioned air whose temperature is adjusted by the first heat exchange unit 300 or the second heat exchange unit 400 in the housing 100 to the interior of the vehicle.

[0083] For example, the first duct member 140 is connected to the inner passage 121 of the first air outlet path 120a. The first duct member 140 is divided into a plurality of routes connected to different locations in the front area in the vehicle interior, thereby providing the air-conditioned air having passed through the first heat exchange unit 300 or the second heat exchange unit 400 to the front area in the vehicle interior.

[0084] The second duct member 150 is connected to the inner passage 121 of the second air outlet path 120b. The second duct member 150 is divided into a plurality of routes connected to different locations in the rear area in the vehicle interior, thereby providing the air-conditioned air having passed through the first heat exchange unit 300 or the second heat exchange unit 400 to the rear area in the vehicle interior.

[0085] As described above, the temperature of the air-conditioned air has been adjusted by the first heat exchange unit 300 and the second heat exchange unit 400 in the housing 100, and can be provided to various areas in the vehicle interior through the first duct member 140 and the second duct member 150. Specifically, the air-conditioned air can be provided to various areas (including the front and rear areas) in the vehicle interior from the single housing 100, thereby reducing the size of the entire package or device for air conditioning in the vehicle interior.

[0086] According to the present invention, various modes can be performed as follows.

[0087] like Fig. 9 As shown, in the cooling mode, the air introduced into the housing 100 through the air inlet path 110 flows to the first heat exchange unit 300 and the second heat exchange unit 400 at the same time. In this case, the air, which has been heat-exchanged with the refrigerant and thus adjusted in temperature of the refrigerant while passing through the first heat exchange unit 300, passes through the first air-conditioning door 210 and is discharged to the outside through the outer passage 122 of the air outlet path 120. The cooling air cooled while passing through the second heat exchange unit 400 passes through the second air-conditioning door 220 and is provided to the interior of the vehicle through the inner passage 121 of the air outlet path 120.

[0088] like Fig.10 As shown, in the heating mode, the air introduced into the housing 100 through the air inlet path 110 flows to the first heat exchange unit 300 and the second heat exchange unit 400 at the same time. The heated air heated while passing through the first heat exchange unit 300 is provided to the interior of the vehicle through the inner passage 121 of the air outlet path 120 through the first air conditioning door 210. In addition, the air that has exchanged heat with the refrigerant while passing through the second heat exchange unit 400 and thus adjusted the temperature of the refrigerant is discharged to the outside through the outer passage 122 of the air outlet path 120 through the second air conditioning door 220.

[0089] like Fig.11 As shown, in the heating / dehumidification mode, air introduced into the housing 100 through the air inlet path 110 simultaneously flows to the first heat exchange unit 300 and the second heat exchange unit 400. In this case, the inside / outside air door 500 may operate to introduce outside air to dehumidify the vehicle interior.

[0090] In this case, a portion of the heated air heated while passing through the first heat exchange unit 300 is provided to the vehicle interior through the inner passage 121 of the air outlet path 120 through the first air conditioning door 210, and the remaining portion of the heated air is discharged to the outside through the outer passage 122. In addition, a portion of the cooled air cooled while passing through the second heat exchange unit 400 is provided to the vehicle interior through the inner passage 121 of the air outlet path 120 through the second air conditioning door 220, and the remaining portion of the cooled air is discharged to the outside through the outer passage 122.

[0091] Therefore, the air heated by the first heat exchange unit 300 and the air dehumidified by the second heat exchange unit 400 are mixed and introduced into the vehicle interior, thereby providing the dehumidified air to the vehicle interior while heating the vehicle interior.

[0092] According to the above-described concept of the present invention, various modes may be realized by controlling the opening degree of the air-conditioning door 200 , and various modes other than the above-described modes may also be realized.

[0093] In the present invention, the first air outlet path 120a is divided into a plurality of routes in the first air-conditioned space S2, and the second air outlet path 120b is divided into a plurality of routes in the second air-conditioned space S3.

[0094] In other words, Figure 3 and Figure 6 As shown, the first air-conditioned space S2 and the second air-conditioned space S3 are arranged to face each other based on the flow space S1, and the first air-conditioned space S2 and the second air-conditioned space S3 are respectively divided into a plurality of routes according to the areas inside the vehicle. Figure 6 , the left side of the housing 100 may be the front side of the vehicle interior, and the right side of the housing 100 may be the rear side of the vehicle interior.

[0095] In this case, if Figure 3 As shown, the outer passage 122 of the first air outlet path 120 a and the outer passage 122 of the second air outlet path 120 b may extend to communicate with the outside of the housing 100 .

[0096] Furthermore, in another embodiment, Figure 6 As shown, the outer passage 122 of the first air outlet path 120a and the outer passage 122 of the second air outlet path 120b may extend in the same direction.

[0097] In other words, the outer passage 122 of the first air outlet path 120a and the outer passage 122 of the second air outlet path 120b extend in the same manner in any (eg, the same) direction, so that the discharge directions of air through the outer passages 122 of the air outlet paths 120 coincide with each other.

[0098] In this case, the outer passages 122 of the first air outlet path 120a and the outer passages 122 of the second air outlet path 120b may extend in a direction opposite to the traveling direction such that outlets of the outer passages 122 are arranged in a direction opposite to the traveling direction.

[0099] Therefore, the air may be smoothly discharged in the direction opposite to the traveling direction through the outer passage 122 of the air outlet path 120 , thereby preventing the discharged air from flowing in the reverse direction.

[0100] Meanwhile, in another embodiment, the housing 100 may include a first exhaust duct 160 configured to communicate with the outer passage 122 of the first air outlet path 120a, and a second exhaust duct 170 configured to communicate with the outer passage 122 of the second air outlet path 120b.

[0101] like Fig.12 As shown, the first exhaust duct 160 may communicate with the outer passage 122 constituting the plurality of first air outlet paths 120a, and the first exhaust duct 160 may be formed to open in the traveling direction of the vehicle.

[0102] In addition, the second exhaust duct 170 may be connected to the outer passage 122 constituting the plurality of second air outlet paths 120 b , and the second exhaust duct 170 may be formed to be open in the traveling direction of the vehicle.

[0103] Therefore, when air is discharged through the outer passage 122 of the first air outlet path 120a and the second air outlet path 120b, wind caused by the vehicle (e.g., air moving relative to the vehicle) passes through the first exhaust duct 160 or the second exhaust duct 170 and flows together with the air discharged through the outer passage 122, thereby improving the performance of exhausting air. In addition, the exhaust air is prevented from flowing in the reverse direction, and sufficient exhaust performance can be ensured even when the vehicle is traveling forward or reverse.

[0104] Although specific embodiments of the present invention have been illustrated and described above, it will be apparent to those skilled in the art that various modifications and variations may be made to the present invention without departing from the technical spirit of the present invention as defined in the claims.
