[0003] The present disclosure relates to a refrigerant cycle device for a vehicle, and more particularly, to a refrigerant cycle device for a vehicle that is included in an air conditioning system for cooling and heating the interior of a vehicle applied to a special purpose vehicle (PBV) and is capable of minimizing the use of pipelines while improving the installability of each component. Background Art

[0004] The vehicle industry has introduced new concepts of future mobility vision to realize a dynamic, human-centric future city.

[0005] One of these future modes of travel is a purpose-built vehicle (PBV).

[0006] PBV is an environmentally friendly mobility solution that provides passengers with the customized services they need while traveling to their destination on the ground, and can use electric vehicle-based artificial intelligence to set the best path for each situation and plan and execute platooning.

[0007] For example, a PBV may be a transportation vehicle and a fixed facility with related technology, and because it has autonomous driving capabilities, a separate driver's seat may be unnecessary. In addition, its interior space may be expandable.

[0008] In some cases, PBVs can perform the role of shuttles that move large numbers of people, and can also be transformed into entertainment spaces such as restaurants, cafes, hotels, and movie theaters, as well as basic facilities such as hospitals and pharmacies.

[0009] In some cases, a PBV may be driven by an electric motor and may include a skateboard-like rolling chassis (referred to in the art as a lower body or skateboard chassis) and an upper body that may carry passengers, wherein batteries are distributed over the lower portion of the rolling chassis.

[0010] In some cases, when the PBV includes an air conditioning system for controlling the indoor temperature of the upper body, it may be difficult to position components included in a refrigerant cycle device of the air conditioning system in a narrow installation space, and the layout of pipes through which the refrigerant flows may become complicated.

[0011] Furthermore, due to the limitation of the installation space of the rolling chassis, some components of the refrigerant cycle device may be installed on the upper body, and thus the inner space of the upper body is reduced.

[0012] A technology mounted on a rolling chassis can simplify the piping of refrigerant cycle equipment and facilitate modularity. Summary of the invention

[0013] The present disclosure has been made in an effort to provide a refrigerant cycle apparatus for a vehicle which is included in an air conditioning system for cooling and heating a vehicle interior applied to a special purpose vehicle (PBV) and which can minimize the use of pipelines while improving the mountability of each constituent element.

[0015] The first fluid pipeline mounting plate may include: a first bracket to which the compressor is placed and fixed; and a first fluid pipeline plate portion bent from the first bracket to be coupled to the second fluid pipeline mounting plate.

[0016] The first fluid pipeline plate portion may be formed perpendicular to the first bracket so that the first fluid pipeline mounting plate may be L-shaped.

[0020] The second fluid manifold plate portion may include: a plurality of second through holes formed to correspond to at least one heat exchanger and at least one valve; and a plurality of second grooves selectively connected to the second through holes on an inner surface facing the first fluid manifold plate portion.

[0021] The first groove and the second groove may be formed in the same shape.

[0022] In a state where the first fluid piping plate portion and the second fluid piping plate portion are coupled to each other, the first groove and the second groove may form a plurality of fluid lines to allow refrigerant to flow therethrough.

[0023] Each of the first bracket and the second bracket may be provided with at least one bushing unit to minimize the transmission of vibration generated from the compressor, the at least one heat exchanger, or the at least one valve.

[0026] The at least one heat exchanger may be configured to condense or evaporate the internally introduced refrigerant by exchanging heat with the coolant.

[0027] At least one heat exchanger may include: a first heat exchanger configured to condense or evaporate refrigerant selectively supplied through a fluid line; a second heat exchanger configured to condense or evaporate refrigerant selectively supplied from a compressor or the first heat exchanger through a fluid line; and a third heat exchanger configured to condense or evaporate refrigerant selectively supplied from a compressor or the first heat exchanger through a fluid line.

[0028] At least one valve may include two valves of a first valve and a second valve, which are connected between the compressor and the first heat exchanger, the second heat exchanger and the third heat exchanger through fluid pipelines so that the refrigerant supplied from the compressor selectively flows into the first heat exchanger, the second heat exchanger or the third heat exchanger.

[0029] The first valve and the second valve may be configured to control the flow movement of the refrigerant or to selectively expand the introduced refrigerant.

[0030] The refrigeration cycle apparatus may further include a gas-liquid separator configured to separate gaseous refrigerant or liquid refrigerant from the refrigerant condensed or evaporated while passing through the at least one heat exchanger.

[0033] In some embodiments, a refrigerant cycle apparatus for a vehicle included in an air conditioning system for cooling and heating the interior of a vehicle applied to a special purpose vehicle (PBV) can reduce manufacturing costs by minimizing the use of pipelines while improving the mountability of each constituent element.

[0034] In some examples, heat losses that may occur as the refrigerant moves may be minimized by minimizing the use of tubing through which the refrigerant circulates.

[0035] In some instances, it is also possible to simplify the layout in a narrow space at the front of the vehicle and improve installability, assembly, and maintainability by promoting modularization of the refrigerant cycle device.

[0036] In some examples, an interior space of a vehicle that can be applied to various purposes may be maximized by mounting a modular refrigerant cycle apparatus on a vehicle body in a special purpose vehicle (PBV). BRIEF DESCRIPTION OF THE DRAWINGS

[0046] In some embodiments, the refrigerant cycle apparatus may be applied to, for example, a purpose-based mobile tool (special purpose vehicle: hereinafter referred to as PBV).

[0047] The PBV is an environmentally friendly mobility vehicle based on an electric vehicle that provides customized services to passengers while traveling to a destination located on the ground.

[0048] The PBV can set an optimal path for each situation and perform platoon driving, and furthermore, the PBV can be a box-type design vehicle with a large interior space.

[0049] Such a PBV comprises a skateboard-like rolling chassis (also referred to in the art as a lower body) and an upper body mounted on the rolling chassis.

[0050] The battery assembly may be mounted on a rolling chassis and a drive motor may be mounted.

[0051] In some embodiments, reference Figures 1 to 7 The vehicle refrigerant cycle device 100 can be set in an air-conditioning system for cooling and heating the interior of a vehicle applied to a special purpose vehicle (PBV), and the vehicle refrigerant cycle device is constructed to improve the installability of each component and at the same time reduce the manufacturing cost by minimizing the use of pipes.

[0052] In some embodiments, the refrigeration cycle apparatus 100 may include a compressor 110 , at least one heat exchanger 120 , at least one valve 130 , and a refrigerant fluid line unit 140 .

[0053] First, the compressor 110 may compress the introduced refrigerant. The at least one heat exchanger 120 may exchange heat between the introduced refrigerant and the coolant.

[0054] The at least one heat exchanger 120 condenses or evaporates the refrigerant introduced therein by exchanging heat with the coolant.

[0055] That is, the at least one heat exchanger 120 may be a water-cooling type heat exchanger for exchanging heat between the introduced refrigerant and the coolant.

[0056] In some embodiments, at least one valve 130 may be provided to selectively allow the refrigerant to flow through the at least one heat exchanger 120. The at least one valve 130 may control the flow of the refrigerant or may selectively expand the introduced refrigerant.

[0057] The refrigerant fluid line unit 140 may be installed in the vehicle body. The compressor 110 , at least one heat exchanger 120 , and at least one valve 130 may be installed on the refrigerant fluid line unit 140 .

[0058] Furthermore, a plurality of fluid lines 102 may be formed inside the refrigerant fluid line unit 140 so that the refrigerant flows to the compressor 110 and the at least one heat exchanger 120 through selective operation of at least one valve 130 .

[0059] In some examples, the refrigerant fluid line unit 140 may include a first fluid line mounting plate 150 and a second fluid line mounting plate 160 coupled to each other.

[0060] The first fluid pipeline mounting plate 150 includes a first bracket 152 and a first fluid pipeline plate portion 154 .

[0061] First, the first bracket 152 may be installed on the vehicle body, and the compressor 110 may be placed and fixed on the first bracket 152 .

[0062] In some examples, at least one first opening 152 a may be formed in the first bracket 152. The at least one first opening 152 a may be applied in order to reduce the overall weight of the first fluid pipeline mounting plate 150.

[0063] Furthermore, the first fluid piping plate portion 154 may be bent from the first bracket 152 and formed integrally therewith, so that the second fluid piping mounting plate 160 may be coupled to the first fluid piping plate portion.

[0064] That is, the first fluid pipeline plate portion 154 is formed to be perpendicular to the first bracket 152 so that the first fluid pipeline mounting plate 150 may be L-shaped.

[0065] The first fluid line plate portion 154 may include a plurality of first through-holes 156 and a plurality of first grooves 158 .

[0066] A plurality of first through holes 156 may be formed in the first fluid pipeline plate portion 154 to supply refrigerant to the compressor 110 or receive refrigerant from the compressor 110 .

[0067] That is, the compressor 110 is mounted on the first bracket 152 and may be connected to the first penetration hole 156 through a connection member 112 located on an outer surface of the first fluid line plate portion 154. The connection member 112 may be formed as a hose or a pipe.

[0068] In addition, the first grooves 158 may be provided in plurality, and the first grooves are selectively connected to the first through holes 156 on the inner surface of the first fluid pipeline plate portion 154 facing the second fluid pipeline mounting plate 160 .

[0069] In some embodiments, the second fluid line mounting plate 160 may include a second bracket 162 and a second fluid line plate portion 164 .

[0070] First, the second bracket 162 may be mounted on the vehicle body. In some examples, at least one second opening 162 a may be formed in the second bracket 162. The at least one second opening 162 a may be applied in order to reduce the overall weight of the second fluid line mounting plate 160.

[0071] Furthermore, the second fluid piping plate portion 164 may be bent from the second bracket 162 and formed integrally therewith to be coupled to the first fluid piping plate portion 154 .

[0072] That is, the second fluid pipeline plate portion 164 is formed perpendicular to the second bracket 162 so that the second fluid pipeline mounting plate 160 may be L-shaped.

[0073] In some examples, the second fluid manifold plate portion 164 may be formed in a shape similar to the first fluid manifold plate portion 154. In addition, at least one heat exchanger 120 and at least one valve 130 may be mounted on an outer surface of the second fluid manifold plate portion 164.

[0074] In some examples, the second fluid manifold plate portion 164 may include a plurality of second through-holes 166 and a plurality of second grooves 168 .

[0075] First, a plurality of second through-holes 166 may be formed on the second fluid pipeline plate portion 164 corresponding to at least one heat exchanger 120 and at least one valve 130 .

[0076] Therefore, at least one heat exchanger 120 and at least one valve 130 may be mounted on the second fluid manifold plate portion 164 through the plurality of second through holes 166 .

[0077] Furthermore, a plurality of second grooves 168 may be selectively connected to the second through holes 166 on the inner surface of the second fluid pipeline plate portion facing the first fluid pipeline mounting plate 150 .

[0078] In some embodiments, the first groove 158 and the second groove 168 may be formed to have the same shape as each other.

[0079] Furthermore, in a state where the first fluid piping plate portion 154 and the second fluid piping plate portion 164 are coupled to each other, the first grooves 158 and the second grooves 168 may form a plurality of fluid lines 102 to enable refrigerant to flow therethrough.

[0080] In some embodiments, the at least one heat exchanger 120 may include a first heat exchanger 122 , a second heat exchanger 124 , and a third heat exchanger 126 .

[0081] First, the first heat exchanger 122 may condense or evaporate the refrigerant selectively supplied from the compressor 110 through the fluid line 102 .

[0082] The second heat exchanger 124 and the third heat exchanger 126 may condense or evaporate the refrigerant selectively supplied from the compressor 110 or the first heat exchanger 122 through the fluid line 102 .

[0083] In some examples, the first heat exchanger 122 , the second heat exchanger 124 , and the third heat exchanger 126 may be selectively supplied with refrigerant from the fluid line 102 through operation of at least one valve 130 .

[0084] That is, according to the selective operation of at least one valve 130 , the compressor 110 , the first heat exchanger 122 , the second heat exchanger 124 , and the third heat exchanger 126 may be interconnected through the fluid line 102 .

[0085] By operating at least one valve 130 according to a heating mode or a cooling mode of the vehicle, the first heat exchanger 122 , the second heat exchanger 124 , and the third heat exchanger 126 may be selectively supplied with the refrigerant from the compressor 110 .

[0086] As an example, when the refrigerant is supplied from the compressor 110 to the first heat exchanger 122 , the refrigerant passing through the first heat exchanger 122 may be introduced into the second heat exchanger 124 or the third heat exchanger 126 .

[0087] In some embodiments, the at least one valve 130 may include a first valve 132 and a second valve 134 .

[0088] The first valve 132 and the second valve 134 may be connected between the compressor 110 and the first heat exchanger 122 , the second heat exchanger 124 , and the third heat exchanger 126 through the fluid line 102 to allow the refrigerant supplied from the compressor 110 to selectively flow into the first heat exchanger 122 , the second heat exchanger 124 , or the third heat exchanger 126 .

[0089] In some examples, the first valve 132 and the second valve 134 may control the flow movement of the refrigerant or selectively expand the introduced refrigerant.

[0090] That is, the first valve 132 and the second valve 134 may control the flow movement of the refrigerant introduced from the compressor 110 or the at least one heat exchanger 120 , and selectively expand the introduced refrigerant and flow the expanded refrigerant to the at least one heat exchanger 120 .

[0091] The first valve 132 and the second valve 134 may be mounted on an outer surface of the second fluid manifold plate portion 164 .

[0092] In some embodiments, each of the first bracket 152 and the second bracket 162 may be provided with at least one bushing unit 170 to minimize transmission of vibration generated by the compressor 110 , the at least one heat exchanger 120 , or the at least one valve 130 to the vehicle body.

[0093] That is, the bushing unit 170 may minimize the transmission of vibration generated by the compressor 110 to the vehicle body frame through the first bracket 152 and the second bracket 162 .

[0094] The bushing unit 170 may include a vibration isolator 172 and a stud 174 .

[0095] First, the outer circumference of the vibration isolator 172 may be vulcanized and bonded to a bushing hole formed on each of the first bracket 152 and the second bracket 162. The vibration isolator 172 may be formed in a bridge shape and a column shape having a through hole, and its material may be composed of a rubber material.

[0096] Furthermore, the outer periphery of the stud 174 may be vulcanized and bonded to the center of the vibration isolator 172 and fastened to the vehicle body frame.

[0097] Therefore, when vibration in a vertical direction is generated from the compressor 110 , the vibration isolator 172 may absorb the vertical vibration of the compressor 110 .

[0098] Furthermore, in addition to the vibration in the vertical direction generated from the compressor 110 , the remaining vibration is also transferred to the vibration isolator 172 through the stud 174 , and can be effectively vibration-insulated by using the elastic force of the vibration isolator 172 .

[0099] In some embodiments, the stud 174 is described as being vulcanized and bonded to the vibration isolator 172 of the bushing unit 170 , but is not limited thereto.

[0100] That is, the stud 174 may be replaced with an inner ring member that can be bolted to the center of the bushing unit 170 and vulcanized and bonded to the vibration isolator 172 .

[0101] In some embodiments, the refrigeration cycle apparatus 100 may further include a gas-liquid separator 180 configured to separate gaseous refrigerant or liquid refrigerant from the refrigerant condensed or evaporated while passing through the first heat exchanger 122 , the second heat exchanger 124 , or the third heat exchanger 126 .

[0102] In some embodiments, the gas-liquid separator 180 may be mounted on an outer surface of the second fluid piping plate portion 164 and located between the first heat exchanger 122 and the second heat exchanger 124 .

[0103] The refrigerant flowing out of the first heat exchanger 122 , the second heat exchanger 124 , or the third heat exchanger 126 and introduced into the fluid line 102 may flow into the gas-liquid separator 180 .

[0104] The gas-liquid separator 180 may be connected to the at least one valve 130 through the fluid line 102 , and may be connected to the compressor 110 .

[0105] That is, the gas-liquid separator 180 may separate the gaseous refrigerant and the liquid refrigerant from the refrigerant passing through the first heat exchanger 122 , the second heat exchanger 124 , or the third heat exchanger 126 .

[0106] The gas-liquid separator 180 may supply gaseous refrigerant among the refrigerant introduced from the first heat exchanger 122 , the second heat exchanger 124 , or the third heat exchanger 126 to the compressor 110 .

[0107] Therefore, the gas-liquid separator 180 may supply only the gaseous refrigerant to the compressor 110 , thereby improving the efficiency and durability of the compressor 110 .

[0108] Therefore, when the refrigerant cycle device of a vehicle configured as described above is applied and is included in an air-conditioning system for cooling and heating the interior of a vehicle applied to a special purpose vehicle (PBV), the manufacturing cost can be reduced by minimizing the use of pipes while improving the installability of each component.

[0109] Furthermore, according to the present disclosure, heat loss that may occur when the refrigerant moves can be minimized by minimizing the use of pipes through which the refrigerant circulates.

[0110] According to the present disclosure, it is also possible to simplify the layout in a narrow space in the front of the vehicle and improve the installability, assembling, and maintainability by promoting modularization of the refrigerant cycle device 100 .

[0111] Furthermore, according to the present disclosure, it is possible to maximize the indoor space of a vehicle that can be applied to various purposes by mounting the refrigerant cycle apparatus 100 modularized in a special purpose vehicle (PBV) on a vehicle body.

[0112] While the disclosure has been described in connection with what are presently considered to be practical embodiments, it is to be understood that the disclosure is not limited to the disclosed embodiments, but on the contrary, the disclosure is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
