Parking lot of the present invention facility is a kind of space, and this space obtains by the configuration space that transforms in the described allocation of facility, and temporarily depositing or to park fuel cell electric vehicle, this fuel cell electric vehicle is equipped with the fuel cell as energy converter.The example of parking lot facility comprises dwelling house garage and underground parking or sky parking, in this dwelling house garage, can park one or two to three fuel cell electric vehicles, this underground parking or sky parking can hold a lot of fuel cell electric vehicles (for example, 10 or more than 10 vehicle, to extensive parking lot be 100 or more than 100 vehicle).
Treatment facility of the present invention is a kind of operating room, and this operating room obtains by the configuration space that transforms in the allocation of facility, so that can carry out energy converter or the work of treatment of the device of energy converter is installed.Illustrate in passing, will consider that below treatment facility illustrates member and modification pattern, but this explanation can be applied to allocation of facility and parking lot facility in practically identical mode.
The work of treatment of device is meant the work that relates to manufacturing, detection or the maintenance etc. of the experiment of described device or described device such as execution.Described chamber is used as term, is meant by partition wall and the space of separating on every side.Therefore, described operating room is meant the working space of dealing with the work with execution by partition wall and extraneous apart, promptly is used to the workplace of dealing with the work.Partition wall is configured for the border with working space in the operating room and extraneous apart.Partition wall also comprises vertically or the side of configuration obliquely and the ceiling face and the bottom surface of configuration obliquely or flatly.Partition wall does not need to be sealed shut working space, but can have opening, the scavenge port that for example is used to insert or take out the opening of energy converter or is used to realize natural ventilation.
Gas supply/output mechanism is by utilizing mechanical energy, as being stored in Compressed Gas in the cylinder by fan or by release, provides the mechanism of ventilation forcibly in the operating room.The process of executing can just be supplied with, just discharge or have concurrently and supply with and discharge.For example, can adopt nonflammable gas/inert gas such as nitrogen and helium or air as diluent gas.
According to this structure, can realize a kind of treatment facility (as detection/maintenance facility, manufacturing facility or Experimental Establishment), this treatment facility promptly dilutes from energy converter and leaks to the inflammable gas of operating room and gas is discharged from the operating room.Therefore, even when gas leakage takes place, also can guarantee the fail safe in the operating room fully.In addition, can also this technology be implemented in the facility described in the above-mentioned patent documentation 1, have the advantage that low-cost and easy-to is introduced by introducing gas supply/output mechanism.
In aspect of treatment facility of the present invention, inflammable gas is the gas lighter than diluent gas, and gas supply/output mechanism is supplied with diluent gas from below, operating room (for example, below the allocation position of energy converter), and gas is discharged from the top of operating room.In this case, the inflammable gas in diluent gas is owing to the convection current that density contrast causes is risen.Therefore, consider that expectation does not change flowing of this free convection, the mobile of diluent gas is set to from the bottom to top.Mainly be meant from the ceiling face of partition wall from the discharge of operating room top and discharge.Supply below the allocation position of energy converter realizes by for example supplying with from the bottom surface.In this structure,, then expect especially that in order to discharge inflammable gas rapidly inflammable gas is lighter than the gas that is full of the operating room if diluent gas is different from the gas (being generally air) that is full of the operating room at common duration of work.If diluent gas (and the gas that is full of the operating room at common duration of work) is lighter than inflammable gas, then gas supply/output mechanism can be set at from the allocation position top supply diluent gas and the gas of energy converter and discharge from the below (as from the bottom surface) of operating room.

Treatment facility of the present invention on the other hand in, satisfy predetermined condition if detect inflammable gas, then control device starting gas supply/output mechanism.That is, supply/output mechanism is set to, and gas supply/output mechanism is inoperative usually, if but detect inflammable gas (to be equal to or greater than the level of set point), then gas supply/output mechanism is started with rapid discharge gas.This is configured in realizes that energy-conservation and quiet environment aspect is effective.And when the work of treatment of the device that does not adopt inflammable gas to carry out mixed execution with the work of treatment of the device that adopts inflammable gas to carry out, this structure that only just starts gas supply/output mechanism where necessary can act on effectively.
Treatment facility of the present invention on the other hand in, top or bottom in the operating room are provided with ramp structure, the accumulation of this ramp structure is because the inflammable gas that rises or descend with the density contrast that is full of the gas of operating room at common duration of work, and the inflammable gas accumulated of inflammable gas sensor.Ramp structure is meant the structure with inclined surface, and this inclined surface is used to guide and accumulate the inflammable gas of convection current.Ramp structure can be formed by partition wall or bottom surface, or forms independently with partition wall or bottom surface.Although the shape to inclined surface has no particular limits, if this inclined surface has as funnelform two-dimentional curved surface, then horizontal movement can be controlled as towards a bit, and this has just improved the degree of condensation of inflammable gas.By this way the inflammable gas of Ji Zhonging can supply with by gas/output mechanism discharges, also can not utilize gas supplys/output mechanism and utilize free convection (for example, by simply on top or the bottom outlet is set) discharge.
Treatment facility of the present invention on the other hand in, satisfy predetermined condition if detect inflammable gas, then control device increase to be supplied with and discharge rate by gas supply/output mechanism.That is,, then increase ventilation volume if detect inflammable gas (to be equal to or greater than the level of set point).According to the amount of gas, it can be a step or multistep or unlimited step to the transformation that increases.
Treatment facility of the present invention on the other hand in, gas supply/output mechanism has a plurality of supply ports that are arranged on mutually different position or a plurality of outlets that are arranged on mutually different position, satisfy predetermined condition if detect inflammable gas, then among a plurality of supply ports or outlet, control device changes the supply port that will be started or the combination of outlet.Typically, if detect inflammable gas (to be equal to or greater than the level of set point), then increase the quantity of supply port or outlet.As a result, making to increase gas flow and change gas flow direction becomes possibility, thereby promotes ventilation.The example that changes direction comprises a kind of like this pattern, in this pattern, the common supply of being undertaken by bottom surface by the operating room and ceiling face and discharge mobile the serve as reasons supply undertaken by the relative side of operating room and the horizontal direction of discharge of being changed that be set at vertical direction.Another example is a kind of like this pattern, wherein, if treatment facility is huge, then the supply port that will be started or the pattern of outlet are changed, to improve scavenging efficiency in the detection target zone of the transducer that is satisfying predetermined condition among the transducer of a plurality of settings.
Treatment facility of the present invention on the other hand in, gas supply/output mechanism comprises the loop, at least a portion that this loop is used for the gas of will discharge from the operating room resupplies to the operating room, satisfies predetermined condition if detect inflammable gas, and then control device suppresses or stops gas circulation.That is, if do not detect inflammable gas (to be equal to or greater than the level of set point), then at least a portion of (after providing any necessary processing to remove any inflammable gas) gas is recycled.But, when detecting inflammable gas (to be equal to or greater than the level of set point), be 0 to make new diluent gas flow into by reducing internal circulating load or setting internal circulating load, dilution effect is enhanced.
Treatment facility of the present invention on the other hand in, a kind of vehicle that energy converter is installed detects in the operating room and keeps in repair.

In pipeline 50, be provided with choke valve (air damper) 70,72 and 74, as the movable platen that is used to control air flows.Choke valve 70 is located between the branch and outlet 54 of leading to circulating line 56 in the discharge duct 52, to regulate internal circulating load and to the discharge rate of outside.Choke valve 72 is located in the circulating line 56 between the branch of discharge duct 52 and the inlet 58, to regulate internal circulating load.Choke valve 74 is located at inlet 58 places, to regulate the inlet of fresh air.These choke valves 70,72 and 74 constitute gas supply/output mechanism with inlet duct 30, exhaust apparatus 40 and pipeline 50, to realize the ventilation of vehicle maintenance chamber 20.
The operation of vehicle maintenance facility 10 is described with reference to Fig. 1 and Fig. 2 subsequently.Similar with Fig. 1, Fig. 2 is the figure that vehicle maintenance facility 10 is shown, and identical component part indicates with identical Reference numeral, and the explanation that repeats will be omitted.
As shown in Figure 1, before being set to the service position, the maintenance vehicle 110 that fuel cell is installed enters the working space 22 of 20 inside, vehicle maintenance chamber.Adopt the equipment and the instrument (not shown) that are provided with in the working space 22, the operator carries out various detection/maintenance works.
At least when execution related to the work of fuel cell, operator's maneuver control device 90 was with the air handling system of starting vehicle Maintenance Room 20 inside.That is to say that inlet duct 30 and exhaust apparatus 40 are set to unlatching, so that little air 28 flows to ceiling wall 26 from the bottom surface in working space 22.At this moment, choke valve 70 is set to slight opening so that about 10% exhaust is discharged to outdoor.Choke valve 72 remains on the complete opening state and circulates to keep stably.Choke valve 74 also is set to slight opening with by inlet 58 air from outdoor suction about 10%, passes through the air that choke valve 70 is discharged thereby compensate.Result's flow air in working space 22 about 90% is the air of taking a breath again, and about 10% is the air that newly enters.
When the operator carried out maintenance work to maintenance vehicle 110, hydrogen may leak.Because autologous density is little, leakage hydrogen gas rises rapidly.Although in some cases, hydrogen can be stayed the positions such as hollow parts of vehicle, and most of hydrogen can still be extruded rapidly by air stream.Then, after the top that arrives working space 22, hydrogen is along with integrated air stream enters discharge duct 52 from exhaust apparatus 40.In this way, hydrogen dilutes by free convection and ventilation in the vehicle maintenance chamber 20.
In discharge duct 52, hydrogen sensor 80 detects amounts of hydrogen with the very little sampling interval (for example 1 second).Air-flow in the discharge duct 52 can become turbulent flow usually under the influence of the fan of exhaust apparatus 40, hydrogen sensor 80 similarly can serve as to detect target with the air of any outflow exhaust portion 42,44 and 46.Hydrogen sensor 80 does not have the hydrogen that the detection of omission ground wherein mixes then.
In control device 90, amount and predetermined threshold value table 96 that comparing section 94 compares by hydrogen sensor 80 detected hydrogen are with the pattern of the definite air conditioning operation that will carry out.For example, when the amount of detected hydrogen is 0 or when considerably less, as mentioned above, carry out the operation that wherein about 90% air is recycled.Therefore when working space 22 is heated or cooled, under the situation that does not reduce its efficient, can also introduce an amount of fresh air.
Here, suppose and leaked quite a large amount of hydrogen.In this case, hydrogen sensor 80 detects this a large amount of relatively hydrogen and exports detection information to control device 90.Then, comparing section 94 is with reference to threshold value table 96, the air conditioning operation of next step that determine must to carry out at the amount of detected hydrogen.
Fig. 2 is illustrated in air conditioning operational instances in this case.This operation is characterised in that although do not change by the ventilation volume of inlet duct 30 and exhaust apparatus 40, air circulation is stopped.That is, choke valve 70 is in wide-open state, so that air is guided to outlet 54 reposefully from discharge duct 52.Choke valve 72 is in closed condition, to forbid air circulation.Then, choke valve 74 is in complete open state, so that the air of q.s can be inhaled into by inlet.
As a result, leakage hydrogen gas will promptly be expelled to outdoor from outlet 54.Therefore, the hydrogen concentration in the vehicle maintenance chamber 20 will remain on enough low level, thereby guarantee fail safe.If detect more substantial hydrogen, then can when being remained on state shown in Figure 2, choke valve 70,72 and 74 improve the running level of inlet duct 30 and exhaust apparatus 40.Therefore, Hydrogen Energy enough is expelled to outdoor with diluted rapidly.
Next, with reference to Fig. 3 A and Fig. 3 B a variation is described.Fig. 3 A and Fig. 3 B be among Fig. 2 vehicle maintenance chamber 20 from the schematic diagram shown in the side of maintenance vehicle 110.Fig. 3 A illustrates the appearance of air conditioning under the usual conditions, and Fig. 3 B illustrates when detecting hydrogen and exceeds the appearance of air conditioning when imposing a condition.
Ventilation state among Fig. 3 A is identical with the described ventilation state of Fig. 1.That is, by making air flow to the outlet 130,132 and 134 be located on the ceiling wall and discharge small quantity of hydrogen from being located at air inlet 120,122 and 124 on the bottom surface.
If detect a large amount of hydrogen, then hydrogen must be expelled to outdoor rapidly.In Fig. 3 B, a large amount of air are blowed to the rear portion with rapid execution exhaust by the front portion from vehicle maintenance chamber 20.Promptly, usually from bottom to top ventilation is stopped under the state, replace, be located on the place ahead wall of vehicle maintenance chamber 20 air inlet 140 and 142 and the outlet 150 and 152 be located on the wall of rear be unlocked, and with torrent air is blown to outdoor by large-scale fan.The air inlet 140 of upside and outlet 150 be set at the ceiling wall near, even make hydrogen, also hydrogen can be discharged effectively owing to convection current remains near the ceiling wall.Therefore, when detecting a large amount of hydrogen, not only ventilation volume is changed, and as mentioned above, and the ventilation direction also is changed realizing effective discharge, thereby can further guarantee fail safe.
If there is not the operator to enter vehicle maintenance chamber 20, inert gas (nonflammable gas) the replacement air that is blown into such as nitrogen or helium also is effective.Promptly, be blown into inert gas and replace air by providing as diluent gas or with the function of inert gas and air mixed, and the function that changes the ratio of the air that flows as diluent gas and inert gas at least, can be only satisfy when imposing a condition when detecting inflammable gas, increase the ratio of the inert gas in the diluent gas, or diluent gas is changed to inert gas.Even the operator enters vehicle maintenance chamber 20, this structure also has the leeway of enforcement.For example, by flowing into helium from the position that is higher than the operator, make it possible to guarantee that operator's safety breathes, and can make hydrogen and air insulated by coating hydrogen with helium that wherein hydrogen is the lightest and remain near the ceiling, helium is the second light gas.
At last, with reference to Fig. 4 another variation is described.Fig. 4 and Fig. 1 much at one, and identical component part indicates with identical Reference numeral, the repetitive description thereof will be omitted.The main distinction of Fig. 4 and Fig. 1 is to have introduced a kind of vehicle maintenance chamber 158, and its ceiling wall 160 is configured to heeling condition.This ceiling wall 160 is set like this, makes ceiling become higher to central point.Apical position from ceiling wall 160 upwards disposes tubule 162 then.And, hydrogen sensor 164 is installed in the inside of tubule 162.
Installed inside at ceiling wall 160 has exhaust apparatus 170.Exhaust apparatus 170 comprises exhaust portion 172,174,176 and 178, and each in these exhaust portion all has outlet and fan.
Next operation according to structure shown in Figure 4 will be described.Here, when the leakage rate of hydrogen for 0 or ventilation is not provided when considerably less.But when hydrogen taking place leak, hydrogen is owing to free convection is risen, and after being guided along the gradient of ceiling wall 160 and by tubule 162, can further be discharged from.Even therefore a spot of hydrogen gas leakage, vehicle maintenance chamber 158 also can keep fail safe fully under the situation that ventilation is not provided.
Simultaneously, in tubule 162, hydrogen sensor 164 detects the amount of hydrogen with the little sampling interval.Testing result is sent to control device 90 then, and is performed based on the control of threshold value table 96.That is, exceed threshold value if detect the amount of hydrogen, then inlet duct 30 and exhaust apparatus 170 are started, and choke valve 70,72 and 74 also is conditioned rapidly hydrogen is expelled to outdoor.
