S30, hydrogen as energy source after cooling for the first time is filled into in hydrogenation plant by surge flask.
It is temperature rise of the mounted gas cylinder in gas injection, especially pressure that hydrogenation stations, which quickly fill the maximum potential risk of battery car,
The main reason for being worth big hydrogen energy source automobile, such as 70Mpa passenger car, causing temperature rise includes: that 1, hydrogen passes through compressor, gas
It is increased by compression temperature；2, hydrogen wherein has " negative joule thomson effect ", and gas also has heating after leaving surge flask；
3, when entering mounted gas cylinder of gas high speed, being converted into thermal energy by kinetic energy is the biggest factor that temperature rises sharply.The present embodiment provides
A kind of temprature control method that hydrogenation stations hydrogen energy source fills can solve the potential wind of temperature rise in above-mentioned generated hydrogenation process
Dangerous problem,.
In step slo, it is considered by the way that pipeline arrangement and special process are safe, the High Temperature Gas from compressor outlet

It is primary cooling, be save the cost, it is cooling for the first time using normal water cooling, it is air-cooled；Enter step by first time cooling gas
Rapid S20 is by gas filling to surge flask, and step S30 waits for that hydrogenation plant includes hydrogen as energy source automobile, and the present embodiment is referred to as battery car,
It is supplied by surge flask to battery car, and longer pipeline is set between surge flask and battery car, this arrangement can allow gas
It is cooled down better by the environment temperature of the Nature.
Preferably, the surge flask adds hydrogen pipeline to be provided with pressure regulator valve with described to hydrogenation plant, as shown in Fig. 2, institute
Step S30 is stated to further comprise the steps of:
S31, judge whether the temperature of the hydrogen as energy source come out from surge flask is higher than the first preset temperature；
S32, if so, judge whether by preset time period, if so, open the pressure regulator valve to hydrogenation plant into
Row hydrogen fills.
It supplies from surge flask to battery car, hydrogen is after " shut off, be depressured, expand ", it may appear that " negative Joule Thompson
Effect ", temperature will increase, and coping with is: consider by the way that pipeline arrangement and special process are safe, real-time monitoring pressure regulation
The gas of valve outlet judges whether be higher than the first preset temperature from the hydrogen of surge flask, will be high if being higher than the first preset temperature
After wet body cools down, be just filled into battery car: the gas for first allowing those to heat up is allowed greatly certainly by longer pipeline
Right environment temperature cools down gas, while stopping preset time period so that gas carried out in atmospheric environment sufficiently it is cold
But, the pressure regulator valve of the present embodiment will as close as possible to surge flask, and far from battery car filling.
Correspondingly, the present embodiment also provides a kind of temperature control system that hydrogenation stations hydrogen energy source fills, as shown in Fig. 2, packet
It includes:
First time refrigerating module 10, for obtaining the hydrogen as energy source after compressor compresses and being carried out for the first time to hydrogen as energy source
It is cooling；
Surge flask fills module 20, for hydrogen as energy source after cooling for the first time to be filled into surge flask；
First hydrogen fills module 30, for hydrogen as energy source after cooling for the first time to be filled into hydrogen to be added by surge flask
In equipment.
Preferably, the surge flask adds hydrogen pipeline to be provided with pressure regulator valve with described to hydrogenation plant, further includes:
First judgment module, for judging whether the temperature of the hydrogen as energy source come out from surge flask is higher than the first default temperature
Degree；
Second judgment module, for judging whether by preset time period, if so, opening the pressure regulator valve to hydrogen to be added
Equipment carries out hydrogen and fills.
The present embodiment is treated hydrogenation plant progress hydrogen energy source using surge flask and is filled by increasing surge flask, while in gas
Body enters before surge flask and carries out after surge flask out gas cooling, save the cost while cooling, to solve gas through over-voltage
Contracting temperature rises sharply and leads to the problem of " negative joule thomson effect " heating by surge flask.
Embodiment two
The present embodiment provides a kind of temprature control methods that hydrogenation stations hydrogen energy source fills, and fill to solve hydrogen from surge flask
Heat caused by thermal energy is converted into as kinetic energy when to mounted gas cylinder, the present embodiment further includes step S40, SA and step S50, is passed through
