  FIG. 1 shows a hydrogen station 10 according to one embodiment of the present invention. The hydrogen station 10 includes a gas supply system 2 and a dispenser 11 which is a filling facility. The gas supply system 2 supplies hydrogen gas to the dispenser 11. The dispenser 11 fills hydrogen gas into the vehicle 9 which is a tank mounting device. The vehicle 9 is, for example, a fuel cell vehicle. The gas supply system 2 includes a gas flow path 20, a compressor unit 21, a gas cooling unit 22, a pressure accumulator unit 23, a precool system 24, a case 4 indicated by a two-dot chain line, and a control unit 29. Equipped with The compressor unit 21, a part of the gas cooling unit 22, and the pressure accumulator unit 23 are disposed on the gas flow passage 20. Hydrogen gas is flowed into the gas flow passage 20 toward the dispenser 11. The control unit 29 controls the compressor unit 21, the pressure accumulator unit 23, and the pre-cool system 24. Most of the devices of the gas supply system 2 are accommodated in the housing 4 (details will be described later).

  The compressor unit 21 is a reciprocating compressor, and includes a drive unit 211 and a compression unit 212. The compression unit 212 has a piston and a cylinder, and the power of the drive unit 211 drives the piston to compress gas in the cylinder. In the present embodiment, the number of compression units 212 is five. The gas cooling unit 22 cools the hydrogen gas discharged from the compression unit 212.

  FIG. 2 is a view showing the configuration of the gas cooling unit 22. As shown in FIG. The gas cooling unit 22 includes a cooling water flow path 220 filled with cooling water, which is a cooling fluid, a cooling water pump 221, a gas cooler 222, and an exhaust heat unit 223. The gas cooler 222 is a microchannel heat exchanger. The gas flow path 20 shown in FIG. 1 and FIG. 2 is connected to the gas cooler 222. The heat removal unit 223 includes a heat exchanger 223a and a fan 223b. In the cooling water flow path 220, a cooling water pump 221, a gas cooler 222, and a heat exchanger 223a of the exhaust heat section 223 are disposed. In the gas cooling unit 22, the hydrogen gas in the gas flow path 20 is cooled by heat exchange between the hydrogen water and the cooling water discharged from the discharge unit of the compression unit 212 in the gas cooler 222. The cooling water that has absorbed heat flows into the heat exchanger 223a of the exhaust heat section 223, and is cooled by the flow of air generated by the fan 223b. The cooled cooling water is again sent to the gas cooler 222 by the cooling water pump 221.

  FIG. 3 is a schematic view of the gas cooler 222. In FIG. 3, illustration of the inflow part and outflow part of cooling water and hydrogen gas is omitted. The gas cooler 222 includes a plurality of first plates 224 and a plurality of second plates 225. The gas cooler 222 is a laminate in which a plurality of first plates 224 and a plurality of second plates 225 are alternately stacked. Plates 224 and 225 adjacent to each other are joined by diffusion bonding.

  FIG. 4 is a plan view of the first plate 224. A plurality of gas flow paths 224 a through which hydrogen gas flows is formed in the first plate 224. FIG. 5 is a plan view of the second plate 225. The second plate 225 is formed with a plurality of cooling channels 225 a through which the cooling water flows. By flowing the cooling water into the cooling flow passage 225a, the hydrogen gas flowing through the gas flow passage 224a is cooled.

  The pressure accumulator unit 23 shown in FIG. 1 comprises four pressure accumulators 231 of the same design pressure. In each pressure accumulator 231, hydrogen gas discharged from the compressor unit 21 is stored.

  The pre-cool system 24 comprises a refrigerator 3 and a brine circuit 5. The brine circuit 5 comprises a brine flow path 240, a brine pump 241, and a pre-cool heat exchanger 242 which is a microchannel heat exchanger. The brine flow path 240 is filled with brine, and the brine pump 241, the precool heat exchanger 242 and the refrigerator 3 are disposed.

  In the brine circuit 5, heat exchange between the hydrogen gas and the brine in the pre-cool heat exchanger 242 cools the hydrogen gas just before being charged from the dispenser 11 to the vehicle 9. The heat absorbed brine flows into the refrigerator 3 and is cooled. The cooled brine is again sent to the precool heat exchanger 242 by the brine pump 241.

  FIG. 6 is a view showing the configuration of the refrigerator 3. The refrigerator 3 includes a refrigerant flow passage 30, an evaporation unit 31, a refrigerant compression unit 32, a condensation unit 33, and an expansion unit 34. The refrigerant is filled in the refrigerant flow path 30 and the evaporation unit 31, the refrigerant compression unit 32, the condensation unit 33, and the expansion unit 34 are disposed. The evaporator 31 is connected to a brine flow path 240 shown in FIGS. 1 and 6. In the evaporation section 31, heat exchange between the brine and the refrigerant cools the brine and evaporates the refrigerant. The refrigerant compression unit 32 illustrated in FIG. 6 compresses the refrigerant flowing out of the evaporation unit 31. The condensing unit 33 includes a heat exchanger 331 through which the refrigerant flows, and a fan 332. The refrigerant flowing from the refrigerant compression unit 32 into the heat exchanger 331 is dissipated by the flow of air generated by the fan 332 and condensed. The expansion unit 34 expands the refrigerant flowing out of the condensation unit 33, and the expanded refrigerant flows into the evaporation unit 31. Thus, in the pre-cool system 24, the brine is cooled by a so-called heat pump cycle.

  When the vehicle 9 shown in FIG. 1 is filled with hydrogen gas, the hydrogen gas sent from a gas supply source (not shown) is compressed in advance by the compressor unit 21 and cooled by the gas cooling unit 22. It is stored in the pressure accumulator unit 23.

  Then, when the vehicle 9 is carried into the hydrogen station 10, hydrogen gas is supplied from the pressure accumulator unit 23 to the dispenser 11, and the dispenser 11 fills the vehicle 9 with hydrogen gas according to a predetermined filling protocol.

  At this time, in the pressure accumulator unit 23, first, hydrogen gas is delivered from the two pressure accumulators 231 (for example, the two pressure accumulators 231 in the upper side of FIG. 1). In the following description, in order to distinguish the two pressure accumulators from the other pressure accumulators, reference numeral "231a" is attached. The dispenser 11 indirectly measures the pressure in the vehicle 9, and if it is determined that the pressure difference between the vehicle 9 and the two accumulators 231a has become equal to or less than a predetermined value, the gas supply system 2 receives Send instructions to stop the delivery of hydrogen gas.

  Subsequently, the gas supply system 2 opens the other pressure accumulator 231 (for example, the third pressure accumulator 231 from the top in FIG. 1), and hydrogen gas is delivered to the dispenser 11. Hereinafter, in the case where the third pressure accumulator is distinguished from the other pressure accumulators, reference numeral 231 b is attached. As a result, the pressure difference between the dispenser 11 (or the pressure accumulator 231b) and the vehicle 9 is recovered, and the flow rate of hydrogen gas charged to the vehicle 9 is secured. If the dispenser 11 determines that the pressure in the tank in the vehicle 9 has risen and the pressure difference between the pressure accumulator 231b and the vehicle 9 has become equal to or less than a predetermined value, the gas supply system 2 sends hydrogen gas from the pressure accumulator 231b. , And the other pressure accumulator (pressure accumulator located at the lower side of FIG. 1) is opened to deliver hydrogen gas. Thereby, a pressure difference between the dispenser 11 and the vehicle 9 is secured, and a sufficient amount of hydrogen gas is filled. If it is determined that the pressure of the tank in the vehicle 9 has become the set value, the supply of hydrogen gas from the gas supply system 2 is stopped.

  As described above, in the pressure accumulator unit 23, two of the four pressure accumulators 231 are used in the low pressure area (for example, 0 MPa to 40 MPa) of the tank of the vehicle 9, and the other one is used in the medium pressure area (40 MPa to 60 MPa) Another one is used in the high pressure region (60 MPa to 70 MPa). As the gas supply system 2 switches the pressure accumulator 231 according to the three pressure regions of the vehicle 9, the dispenser 11 can be efficiently filled with hydrogen gas according to the filling protocol. In addition, by using two pressure accumulators 231a in a low pressure area where the required flow rate of hydrogen gas is larger than the medium pressure area and the high pressure area, the flow rate of hydrogen gas is smaller than when only one pressure accumulator is used. Secured. Therefore, even if the pressure accumulator 231a is small, the filling of the hydrogen gas into the vehicle 9 can be efficiently performed.

  Next, the positional relationship of each device of the gas supply system 2 will be described. In the gas supply system 2, the compressor unit 21 and the pressure accumulator unit 23 are accommodated in a housing 4 indicated by a two-dot chain line. Furthermore, various components of the pre-cool system 24 excluding the pre-cool heat exchanger 242 and the condenser 33 (see FIG. 6) of the refrigerator 3 in the housing 4 and the gas cooling unit 22 excluding the exhaust heat part 223 shown in FIG. Are also housed.

  FIG. 7 is a side view of the gas supply system 2. FIG. 8 is a view of the gas supply system 2 as viewed from the left side of FIG. In FIG. 7 and FIG. 8, the housing 4 is indicated by a two-dot chain line. Further, only the main devices of the gas supply system 2 are illustrated, and illustration of peripheral members such as piping is omitted. In FIGS. 7 and 8, the brine pump 241 of the pre-cool system 24 shown in FIG. 1, the evaporation portion 31 of the refrigerator 3, the refrigerant compression portion 32 and the expansion portion 34 shown in FIG. The reference numeral 24 is attached to the rectangle.

  The housing 4 has a rectangular parallelepiped shape. An opening 421 is formed in the upper portion 42 of the housing 4 and is closed by a lid 422 which can be opened and closed. In the housing 4, the pressure accumulator unit 23 is disposed adjacent to the side of the compressor unit 21 in the Y direction (that is, in the left-right direction of FIG. 7 and in the direction perpendicular to the sheet of FIG. 8). A portion of the precool system 24 is disposed above the accumulator unit 23. In the following description, the Y direction in which the compressor unit 21 and the pressure accumulator unit 23 are disposed is referred to as the “arrangement direction”. The X direction is a direction perpendicular to the arrangement direction in the horizontal plane (that is, a direction perpendicular to the sheet of FIG. 7 and the left and right direction of FIG. 8). The Z direction is perpendicular to the X and Y directions and coincides with the gravity direction. Hereinafter, the Z direction is referred to as "vertical direction".

  The compressor unit 21 and the pressure accumulator unit 23 are explosion proof. Hereinafter, a portion 491 in which the compressor unit 21 and the pressure accumulator unit 23 are disposed in the inside of the housing 4 will be referred to as “explosion-proof unit 491”. In addition, in the explosion-proof unit 491, the electric devices and instrumentations attached to the compressor unit 21 and the pressure accumulator unit 23 are also made to be explosion-proof specifications. On the other hand, the pre-cool system 24 is non-explosion proof. Hereinafter, the part 492 in which the pre-cool system 24 is arrange | positioned among the insides of the housing | casing 4 is called "non-explosion-proof part 492." As shown in FIG. 8, a control unit 29 is disposed in the non-explosion-proof unit 492. The non-explosion-proof unit 492 is also non-explosion-proof in terms of electrical equipment and instrumentation items attached to the pre-cool system 24 and the control unit 29. A gas detection sensor (not shown) is disposed in the explosion-proof unit 491 and the non-explosion-proof unit 492 shown in FIGS. 7 and 8, and leakage of hydrogen gas in the housing 4 is managed.

  The compressor unit 21 is a so-called vertical type, and is disposed in the housing 4 in a state where the compression unit 212 is located above the drive unit 211 in the vertical direction. That is, in the compression unit 212, the piston reciprocates in the vertical direction in the cylinder. The entire compression section 212 overlaps the opening 421 in the vertical direction. Thus, when the compressor unit 21 is maintained, the lid 422 can be opened, and the portion such as the compression unit 212 can be easily taken out of the opening 421 to the outside of the housing 4. The heat removal portion 223 and the condensation portion 33 are separated from the opening 421. In the gas supply system 2, as long as a desired portion of the compressor unit 21 can be taken out, only a part of the compression unit 212 may vertically overlap the opening 421, and the entire compressor unit 21 is the opening 421. And may overlap.

  In the pressure accumulator unit 23, two pressure accumulators 231 of the four pressure accumulators 231 are disposed in the arrangement direction, and the remaining two pressure accumulators 231 are vertically overlapped with the two pressure accumulators 231. Each of the pressure accumulators 231 is a plane substantially perpendicular to the arrangement direction of the four side portions 411 and 412 of the housing 4 which stands vertically to the installation surface, that is, the direction in which the normal extends is parallel to the arrangement direction And extends along a side 411 having a face. Hereinafter, the side portion 411 is referred to as "first side portion 411". Also, two side portions 412 having a surface parallel to the arrangement direction, that is, a surface perpendicular to the extending direction of the pressure accumulator 231 are referred to as “second side portions 412”.

  The gas cooler 222 of the gas cooling unit 22 is fixed to the compression unit 212 of the compressor unit 21 in the explosion-proof unit 491. Further, the cooling water pump 221 (see FIG. 2) is also disposed in the explosion-proof unit 491. The gas cooler 222 and the cooling water pump 221 are explosion proof specifications. The heat removal unit 223 is disposed in the upper portion 42 of the housing 4.

  In the precool system 24, the brine pump 241 shown in FIG. 1, the evaporation portion 31 of the refrigerator 3, the refrigerant compression portion 32 and the expansion portion 34 shown in FIG. The condenser 33 is disposed in the upper portion 42 of the housing 4. The pre-cool heat exchanger 242 is disposed in the vicinity of the dispenser 11 of FIG. The pre-cool heat exchanger 242 may be disposed within the dispenser 11. In the gas supply system 2, since the air-cooling type heat removal part 223 and the condensation part 33 are used, the freedom degree of the installation place is improved as compared with the water-cooling type, and the upper part 42 of the housing 4 is effectively used. Can.

  As described above, the components of the precool system 24 excluding the compressor unit 21, the gas cooling unit 22, the pressure accumulator unit 23, and the precool heat exchanger 242 are provided in the housing 4 or in the upper portion 42 of the housing 4. The gas supply system 2 can be miniaturized.

  The hydrogen station 10 having the gas supply system 2 according to the embodiment of the present invention has been described above, but in the gas supply system 2, the compressor unit 21 is disposed in the housing 4 with the compressor unit 21 facing vertically. At the same time, the pre-cool system 24 is disposed above the pressure accumulator unit 23. The area occupied by the compressor unit 21 can be reduced compared to a so-called horizontal gas supply system in which the compressor unit is disposed in a horizontal plane. By covering the compressor unit 21 and the pressure accumulator unit 23 with one rectangular parallelepiped case 4, a space (in the present embodiment, the non-explosion-proof unit 492) is formed above the pressure accumulator unit 23, At least a portion of the pre-cool system 24 can be disposed within the space. Thereby, the installation area of the gas supply system 2 can be made small, and the miniaturization of the hydrogen station 10 can be achieved.

  In particular, since the pre-cool heat exchanger 242 is a microchannel heat exchanger, the pre-cool heat exchanger 242 can be miniaturized while securing the cooling efficiency of hydrogen gas, and as a result, other devices of the pre-cool system 24 Can also be miniaturized. Thereby, many devices of the pre-cool system 24 can be disposed in the housing 4, and the installation area of the gas supply system 2 can be further reduced.

  Further, since the gas cooler 222 is also a small microchannel heat exchanger, the installation area of the gas supply system 2 can be further reduced by directly fixing the gas cooler 222 to the compression section 212 of the compressor unit 21. . Since the heat removal unit 223 of the gas cooling unit 22 and the condensation unit 33 of the refrigerator 3 are disposed in the upper portion 42 of the housing 4, the gas supply is more than when these members are disposed in locations other than the housing 4. The footprint of the system 2 can be made smaller.

  In the pressure accumulator unit 23, four pressure accumulators 231 are arranged two each in the upper and lower stages. The width in the direction of arrangement of the pressure accumulator units 23 can be reduced as compared to the case where the four pressure accumulators 231 are arranged in parallel, and the height in the vertical direction is higher than when the four pressure accumulators 231 are arranged vertically. Can be reduced. As described above, in the gas supply system 2, the number of pressure accumulators 231 can be secured while suppressing the size of the pressure accumulators 231. In addition, since the longitudinal direction of the pressure accumulator 231 is along the first side 411 of the housing 4, the width in the arrangement direction of the housing 4 is prevented from becoming unnecessarily large, and the installation area of the gas supply system 2 It can be made smaller.

  In the housing 4, a non-explosion-proof unit 492 is formed. As a result, it is not necessary to make the pre-cool system 24 and the control unit 29 be explosion proof specifications, and it is possible to prevent upsizing of these devices and to significantly suppress the cost.

  FIG. 9 is a view showing a part of a hydrogen station 10a according to another example. The dispenser 11 is attached to one of the second side portions 412 having a plane parallel to the arrangement direction of the housing 4. The precool heat exchanger 242 of the precool system 24 is disposed within the dispenser 11. In the structure shown in FIG. 9, the entire hydrogen station 10 a can be miniaturized by attaching the dispenser 11 to the gas supply system 2. At the hydrogen station 10 a, if the dispenser 11 is disposed adjacent to the second side 412, it may be slightly spaced apart from the second side 412.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to the said embodiment, A various change is possible.

  In the hydrogen station 10 a shown in FIG. 9, a pre-cool heat exchanger 242 may be disposed in the housing 4. Also in the gas supply system 2 shown in FIG. 1, the pre-cool heat exchanger 242 can be disposed in the housing 4. In this case, all devices of the compressor unit 21, the gas cooling unit 22, the pressure accumulator unit 23, and the pre-cool system 24 are disposed in the housing 4 or in the upper portion 42 of the housing 4. A cover that covers the heat removal portion 223 and the condensation portion 33 may be attached to the upper portion 42, and all devices may be disposed in the housing 4.

  The gas cooler 222 may be a plate heat exchanger other than the microchannel heat exchanger as long as it is directly fixed to the compression unit 212. In the pressure accumulator unit 23, the number of pressure accumulators 231 need not necessarily be four, and the number of pressure accumulators 231 may be three if the flow rate of hydrogen gas is not required in the low pressure region of the tank of the vehicle 9 . In addition, in the case where the arrangement space is secured in the explosion-proof unit 491, the number of pressure accumulators 231 may be five or more. When the accumulators 231 having a short length are used, a plurality of accumulators 231 form one accumulator group, and the plurality of accumulator groups are arranged in the longitudinal direction of the accumulator 231, that is, in the horizontal plane It may be arranged in a direction perpendicular to the direction.
