The indoor heat exchanger 114 that functions as an evaporator that evaporates the refrigerant, and the gas-liquid separator 115 that separates the liquid from the refrigerant that has passed through the indoor heat exchanger 114 are included.

  Similarly, the other refrigeration cycle apparatus 120 also includes a compressor 121, an outdoor heat exchanger 122 that functions as a condenser, an expander 123, an indoor heat exchanger 124 that functions as an evaporator, and a gas-liquid separator 125.

  In addition, the air conditioner 100 for railway vehicles includes the indoor heat exchangers 114 and 124, the indoor blower 130 that promotes heat exchange with the air in the passenger compartment, the outdoor heat exchangers 112 and 122, and the heat from the air outside the vehicle. An outdoor blower 140 that facilitates replacement is also provided.

  When the indoor heat exchangers 114 and 124 exchange heat with the air in the passenger compartment, moisture in the air is condensed on the surfaces of the indoor heat exchangers 114 and 124. Condensed water, which is water condensed on the surfaces of the indoor heat exchangers 114 and 124, drops from the indoor heat exchangers 114 and 124.

  Therefore, the railcar air conditioner 100 also includes a drain pan 151 that receives the condensed water that drops from one indoor heat exchanger 114, and a drain pan 152 that receives the condensed water that drops from the other indoor heat exchanger 124. The drain pan 151 is arranged below the indoor heat exchanger 114, and the drain pan 152 is arranged below the indoor heat exchanger 124.

  The casing 200 has a box-shaped base frame 210 having a bottom plate, and a top plate 220 that defines an accommodation space for accommodating the railroad vehicle air conditioner 100 together with the base frame 210 by closing an upper opening of the base frame 210. Have and. 1A shows the inside of the casing 200, only a part of the top plate 220 is shown.

  The casing 200 also has partition plates 231 and 232 that partition the accommodation space defined by the base frame 210 and the top plate 220 into an indoor unit room S1, an outdoor unit room S2, and a compressor room S3.

  The indoor heat exchangers 114 and 124, the drain pans 151 and 152, the expanders 113 and 123, and the indoor blower 130 are housed in the indoor unit room S1. The outdoor heat exchangers 112 and 122 and the outdoor blower 140 are accommodated in the outdoor unit room S2. Compressors 111 and 121 and gas-liquid separators 115 and 125 are housed in the compressor chamber S3.

  As shown in FIG. 1B, the top plate 220 is divided into a first top plate 221 and a second top plate 222. The first top plate 221 closes the upper portions of the indoor unit room S1 and the compressor room S3 shown in FIG. 1A. The second top plate 222 closes the upper part of the indoor unit room S2 shown in FIG. 1A.

  A first vent hole 224 is formed on the second top plate 222 above the outdoor blower 140 shown in FIG. 1A. A second vent hole 225 is formed on the second top plate 222 above each of the outdoor heat exchangers 112 and 122 shown in FIG. 1A.

  Outside air is taken into the outdoor unit chamber S2 shown in FIG. 1A through one of the first ventilation hole 224 and the second ventilation hole 225. The air that has exchanged heat with the outdoor heat exchangers 112 and 122 shown in FIG. 1A is discharged to the outside of the vehicle through the other of the first ventilation hole 224 and the second ventilation hole 225.

  The top plate 220 can be opened and closed with respect to the base frame 210 shown in FIG. 1A. Specifically, the top plate 220 is fixed to the base frame 210 shown in FIG. 1A by bolts 223. A maintenance person who maintains the railroad vehicle air conditioner 100 can remove the top plate 220 from the base frame 210 shown in FIG. 1A by loosening the bolt 223.

  By opening the top plate 220 in this manner, the maintenance personnel can access the respective members constituting the railroad vehicle air conditioner 100 from above. Since the top plate 220 is divided into the first top plate 221 and the second top plate 222, only one of the first top plate 221 and the second top plate 222 can be removed.

  Returning to FIG. 1A, the description will be continued. At the bottom surface of the indoor unit room S1, return ports 241 and 242 that open to a passenger compartment (not shown) located below the indoor unit room S1 are opened. One return port 241 is arranged beside the indoor heat exchanger 114, and the other return port 242 is arranged beside the indoor heat exchanger 124.

  The indoor blower 130 described above sucks the air in the passenger compartment into the indoor unit room S1 through the return ports 241 and 242. The air sucked from one return port 241 passes through the indoor heat exchanger 114, and the air sucked from the other return port 242 passes through the indoor heat exchanger 124. Further, the indoor blower 130 returns the air that has passed through the indoor heat exchangers 114 and 124 to the cabin again through a duct (not shown).

  Moisture in the air is condensed on the surfaces of the indoor heat exchangers 114 and 124 while the air in the passenger compartment passes through the indoor heat exchangers 114 and 124. The water condensed in one indoor heat exchanger 114 drops into the drain pan 151, and the water condensed in the other indoor heat exchanger 124 drops into the drain pan 152.

  Therefore, the railcar air-conditioning system 600 also includes an antibacterial agent holder 300 arranged in each of the drain pans 151 and 152 in order to suppress the growth of bacteria in the condensed water accumulated in the drain pans 151 and 152.

  The antibacterial agent holder 300 according to the present embodiment can exhibit a stable antibacterial action without being excessively moved while the railway vehicle is traveling, and is also prevented from excessive movement. As a result, it is possible to avoid the problem of blocking the drainage ports of the drain pans 151 and 152, and the greatest feature is a configuration that can be easily attached and detached during maintenance. Hereinafter, the antibacterial agent holder 300 will be specifically described.

  The configuration of the pair of the indoor heat exchanger 114, the drain pan 151, and the antibacterial agent holder 300 is the same as the configuration of the pair of the indoor heat exchanger 124, the drain pan 152, and the antibacterial agent holder 300. is there. Therefore, the former configuration will be described as a representative.

  As shown in FIG. 2, the antibacterial agent holder 300 is arranged on the drain pan 151 in a state of being attached to the indoor heat exchanger 114 in the railroad vehicle air conditioner 100. Therefore, first, the configurations of the indoor heat exchanger 114 and the drain pan 151 will be described.

  The indoor heat exchanger 114 as a whole is formed in a shape that extends relatively long in one direction (hereinafter, referred to as a longitudinal direction), specifically, a rectangular parallelepiped shape. The indoor heat exchanger 114 has a first end plate 114a as a first end that is one end in the longitudinal direction in which the indoor heat exchanger 114 extends, and a second end that is the other end. And a second end plate 114b. The first end plate 114a and the second end plate 114b are formed in a plate shape protruding outward in the longitudinal direction.

  The drain pan 151 is arranged below the indoor heat exchanger 114. The drain pan 151 has a bottom plate 151a on which the indoor heat exchanger 114 is placed, and a side plate 151b rising from the peripheral edge of the bottom plate 151a. In addition, in FIG. 2, the side plate 151b of the drain pan 151 is shown in a perspective view.

  A first drain port 160, a second drain port 170, and a third drain port 180 for discharging condensed water accumulated in the drain pan 151 are formed on the bottom plate 151a of the drain pan 151, respectively. The first drain outlet 160, the second drain outlet 170, and the third drain outlet 180 are arranged at intervals in a direction parallel to the longitudinal direction of the indoor heat exchanger 114. The first drain port 160 is disposed opposite the first end plate 114a, the second drain port 170 is disposed opposite the second end plate 114b, and the third drain port 180 is the first drain port 160 and the second drain port. It is arranged between 170 and.

  The antibacterial agent holder 300 has a first fastener 310 detachably attached to the first end plate 114a of the indoor heat exchanger 114 and a second fastener 310 detachably attached to the second end plate 114b of the indoor heat exchanger 114. 320, and a linear holding member 330 having one end connected to the first fastener 310 and the other end connected to the second fastener 320.

  The 1st fastener 310 and the 2nd fastener 320 are each comprised by the clip made from stainless steel. The configurations of the first fastener 310 and the second fastener 320 are the same. Therefore, as a representative, the configuration of the first fastener 310 will be described below.

  As shown in FIG. 3, the first fastener 310 faces the first pressure contact portion 311 connected to the holding member 330 and the first pressure contact portion 311, and is disposed between the first pressure contact portion 311 and the first pressure contact portion 311. 2 has a second pressure contact portion 312 that elastically sandwiches the first end plate 114a, and an elastic portion 313 that connects the first pressure contact portion 311 and the second pressure contact portion 312.

  The first press contact portion 311 has a protrusion 311a that projects in a spherical shape toward the first end plate 114a at a portion that elastically presses against one surface in the thickness direction of the first end plate 114a shown in FIG. Similarly, the second press contact portion 312 also has a protrusion 312a protruding toward the first end plate 114a at a portion that elastically presses against the other surface in the thickness direction of the first end plate 114a.

  The first fastener 310 elastically sandwiches the first end plate 114a shown in FIG. 2 in the thickness direction by the protrusion 311a of the first pressure contact portion 311 and the protrusion 312a of the second pressure contact portion 312, thereby causing friction. It is attached to the first end plate 114a by force. When the first fastener 310 is attached to the first end plate 114a, the elastic portion 313 urges the second press contact portion 312 toward the first press contact portion 311.

  In addition, the first fastener 310 has the elastic portion 313 in a state in which the pressure contact between the protrusions 311a and 312a and the first end plate 114a is released, that is, the second pressure contact portion 312 is separated from the first pressure contact portion 311. Is elastically deformed, so that it can be removed from the first end plate 114a.

  The significance of the protrusions 311a and 312a will be described below. In a railway vehicle, the first end plate 114a and the first fastener 310 may slide due to vibration during traveling, and the first end plate 114a may be damaged. In particular, since the first fastener 310 is made of a metal material, specifically, stainless steel, when the above-described sliding occurs, the first fastener 310 is made of a resin material as compared with the case where the first fastener 310 is made of resin. The one end plate 114a is easily scratched.

  The protrusions 311a and 312a are for preventing the above-mentioned scratches from being formed over a wide area. That is, by providing the protrusions 311a and 312a, it is possible to reduce the contact area between the first fastener 310 and the first end plate 114a as compared with the case where the protrusions 311a and 312a are not provided. As a result, even if the sliding occurs, it is difficult for the first end plate 114a to be scratched over a wide area.

  The first fastener 310 has been described above. The second fastener 320 attached to the second end plate 114b shown in FIG. 2 also has the same configuration and operation as the first fastener 310.

  Next, the holding member 330 will be described. The holding member 330 is formed of a chain, as shown in FIG. The chains are made of stainless steel.

  As shown in FIG. 2, the holding member 330 includes a storage bag structure 340 that stores an antibacterial agent having an antibacterial action against condensed water accumulated in the drain pan 151, and is connected to the first fastener 310 from one end to the second stopper. A plurality of pieces, specifically two pieces, are held at intervals in the extending direction over the other end connected to the tool 320.

  The two holding bag structures 340 are placed on the bottom plate 151a of the drain pan 151, and one end of the holding member 330 is fixed to the first end plate 114a through the first fastener 310. The other end of is fixed to the second end plate 114b through the second fastener 320.

  One accommodation bag structure 340 is disposed between the first drainage port 160 and the third drainage port 180, and the other accommodation bag structure 340 includes the third drainage port 180 and the second drainage port 170. It is located between.

  As shown in FIG. 4, each accommodation bag structure 340 includes an accommodation bag 341 that accommodates the antibacterial agent AN, and a mounting tool that detachably retains the accommodation bag 341 and is attached to the holding member 330 shown in FIG. 2. 342.

  As shown in FIG. 5, the accommodation bag 341 has an open end 341a that is open to the outside. The inside of the accommodation bag 341 is filled with the antibacterial agent AN through the opening end 341a. The accommodation bag 341 is configured by a net that allows condensed water to pass therethrough. The net is made of stainless steel.

  Further, the accommodation bag 341 has a catching portion 341b that projects outwardly at the peripheral edge of the opening end 341a. The hook portion 341b is formed by folding the net at the position of the open end 341a.

  Returning to FIG. 4, the description will be continued. The attachment 342 is a clip having an openable / closable sandwiching portion 342a, a spring portion 342b for urging the sandwiching portion 342a in a closing direction, and a lever portion 342c for elastically deforming the spring portion 342b to open the sandwiching portion 342a. It is composed by. The clip is made of stainless steel.

  The sandwiching portion 342a sandwiches the open end 341a of the accommodating bag 341 filled with the antibacterial agent AN in a closed state. As a result, the accommodation bag 341 is held by the attachment 342.

  The sandwiching portion 342a sandwiches the portion of the accommodation bag 341 that is closer to the bottom of the accommodation bag 341 than the catching portion 341b shown in FIG. As a result, even if the force to pull out the storage bag 341 from the sandwiching portion 342a acts on the storage bag 341, the catching portion 341b illustrated in FIG. 5 is caught by the sandwiching portion 342a, so that the storage bag from the sandwiching portion 342a is caught. 341 is prevented from coming off.

  Further, the attachment 342 is formed with a through hole 342d through which the holding member 330 shown in FIG. 2 is inserted. The through hole 342d is formed in the lever portion 342c. The attachment 342 with the holding member 330 inserted through the through hole 342d is fixed to the holding member 330 at the position of the through hole 342d. The fixing can be realized by, for example, tightening and welding using a metal member.

  As shown in FIG. 2, the antibacterial agent holder 300 described above is attached to the indoor heat exchanger 114 in such a manner that the storage bag structure 340 held by the holding member 330 is arranged on the drain pan 151.

  When the condensed water dripping from the indoor heat exchanger 114 collects in the drain pan 151, the condensed water passes through the storage bag 341 shown in FIG. 4 and comes into contact with the antibacterial agent AN in the storage bag 341. Then, the antibacterial agent AN dissolves in the condensed water, and the condensed water has an antibacterial action. For this reason, bacteria are less likely to propagate in the condensed water, and the generation of offensive odor and the generation of sliminess can be suppressed.

  Even if the specific gravity of the antibacterial agent AN is less than 1, the holding member 330 should have a specific gravity such that all the storage bag structures 340 fixed to the holding member 330 are immersed in the condensed water. Is preferred. Since the contact area between the antibacterial agent AN and the condensed water can be secured by immersing the antibacterial agent AN in the condensed water, a high antibacterial action can be obtained as compared with the case where the antibacterial agent AN is floated in the condensed water. .

  According to this embodiment, one end of the holding member 330 is fixed to the first end plate 114a of the indoor heat exchanger 114 through the first fastener 310, and the other end of the holding member 330 is passed through the second fastener 320 to heat the indoor heat. It is fixed to the second end plate 114b of the exchanger 114.

  For this reason, the storage bag structure 340, and by extension, the antibacterial agent AN is prevented from excessively moving during traveling of the railway vehicle. Therefore, the antibacterial agent AN does not move to a position where it is difficult to contact the condensed water, and the antibacterial agent AN can exert a stable antibacterial action on the condensed water.

  Further, since the attachment 342 shown in FIG. 4 is fixed to the holding member 330, movement of the accommodation bag structure 340 with respect to the holding member 330 is restricted. This also contributes to the prevention of excessive migration of the antibacterial agent AN.

  Further, as a result of the excessive movement of the storage bag structure 340 being prevented, the storage bag structure 340 closes the first drain port 160, the second drain port 170, and the third drain port 180 of the drain pans 151 and 152. You can avoid such problems.

  Further, each of the first fastener 310 and the second fastener 320 shown in FIG. 2 is attached to the indoor heat exchanger 114 by elastically pressure contacting with the indoor heat exchanger 114, and the pressure contact is released. When it is elastically deformed, it is removed from the indoor heat exchanger 114. Therefore, the antibacterial agent holder 300 can be easily attached and detached. Therefore, the maintenance of the antibacterial agent holder 300 can be performed quickly.

  Further, the storage bag 341 shown in FIG. 4 can be attached to and detached from the mounting tool 342 by opening and closing the sandwiching portion 342 a of the mounting tool 342. Therefore, it is possible to refill the antibacterial agent AN by removing only the storage bag 341 from the antibacterial agent holder 300 while the first fastener 310 and the second fastener 320 are fixed to the indoor heat exchanger 114. . This also contributes to quick maintenance.

  The top plate 220 shown in FIG. 1B can be opened and closed with respect to the casing 200 shown in FIG. 1A, and when the top plate 220 is opened, the pair of antibacterial agent holders 300, the indoor heat exchangers 114 and 124, and The drain pans 151 and 152 are exposed. Therefore, the maintenance staff can easily access the antibacterial agent holder 300 from above by opening the top plate 220. This also contributes to quick maintenance.

  In addition, in the present embodiment, the holding member 330 is not a rigid body as a whole, but is a member that can be deformed by its own weight, specifically, a chain, depending on the shape of the place to be installed. Therefore, as compared with the case where the holding member 330 is made of a rigid body as a whole, the place where the holding member 330 is installed is less likely to be limited, and the holding member 330 is easily installed.
