Description

[0001] A METHOD FOR PROVIDING A CLIMATE ZONE IN A FUEL DISPENSER AND A FUEL DISPENSER

[0002] Technical field

[0003] The invention relates to a fuel dispenser for dispensing fuel to a vehicle and a method for providing a climate zone in the fuel dispenser.

[0004] Background art

[0005] Safety aspects in and around areas containing fuel dispensing units is today a highly debated field and new technology is constantly developed with the intention to increase the safety within such areas. It is well-known that fuel is a highly inflammable substance that must be handled with extreme care. An inherent property of fuel, that increases the risks of its handling, is its high volatility. For the above reasons, safety standards such as the UL standards for safety in North America, the ATEX directive in the EU or the European standard EN 13617 pertaining to petrol filling stations have been created for fuel handling to reduce the thereby induced risks.

[0006] According to those standards, electromechanical devices, such as the motor or the above-mentioned switching device, must be enclosed in explosion-proof housings or isolated through the use of intrinsically safe circuitry in order to protect against the hazards of a spark igniting fuel vapors.

[0007] Although serious measures have been taken to ensure the safety it is always a concern when highly inflammable substances are handled around fuel dispensing units. It is particularly difficult to ensure safety when the fuel dispensed is gas such as hydrogen, CNG (Compressed Natural Gas) or LPG (Liquefied Natural Gas) that could be dispensed at gaseous state or at liquid state. Indeed, hydrogen can be dispensed at gaseous state or at liquid state, for instance.

[0008] As said, the electromechanical devices have to be protected against hazards of a spark igniting fuel vapor in order to ensure the safety around the fuel dispenser. A problem in this regard is that at least some electromechanical devices have limited operating temperature specifications. A further problem in this regard is that the electromechanical devices may be overheated and thereby not being able to operate as expected. Summary of the invention

[0009] It is an objective of the present invention to mitigate, alleviate or eliminate one or more of the above-identified deficiencies in the art and disadvantages singly or in any combination and solve at least the above-mentioned problems.

[0010] According to a first aspect of the invention, these, and other objects, and / or advantages that will be apparent from the following description of embodiments, are achieved, in full or at least in part, by a method for providing a climate zone in a fuel dispenser arranged for dispensing fuel to a vehicle.

[0011] The method comprising the steps of: determining an inside temperature of an electronics module of the fuel dispenser; comparing the inside temperature with a predetermined temperature range; and if the inside temperature is outside the predetermined temperature range, adjusting the inside temperature by providing heat or cooling to the electronics module.

[0012] This is advantageous as it facilitates for controlling the inside temperature of the electronics module in an easy and efficient way and, thus, provide a climate zone in the electronics module of the fuel dispenser. With this design, it may allow for controlling the inside temperature, comparing the inside temperature with the predetermined temperature range, and adjusting, if needed, the inside temperature so as the climate zone is maintained. Thus, it should be noted that the method may be arranged for providing and maintaining the climate zone in the fuel dispenser. The determination of the inside temperature and the comparison between the inside temperature and the predetermined temperature range may be performed continuously such that the climate zone may be maintained. The determination of the inside temperature and the comparison between the inside temperature and the predetermined temperature range may be performed with a predetermined time interval, i.e. once every day, once every hour or the like, such that the climate zone may be maintained.

[0013] The electronics module may comprise electromechanical devices and with this design, it is possible to provide a favorable environment for the electromechanical devices comprised in the electronics module. In conventional solution, the electromechanical devices may be enclosed in different types of housings. With this design, the housing of the electromechanical devices may be removed, and the devices may thus be comprised in the electronics module without their respective housings. This is advantageous as it provides for a cost-efficient solution. This may be further advantageous as it allows for a reduced risk of overheating the devices due to poor ventilation by way of example. This may be achieved in that it is possible to provide cooling to the electronics module in an easy and efficient way and thereby cooling the devices as well.

[0014] This is further advantageous as it allows for an increased temperature specification for the electronics module compared to conventional solutions.

[0015] By the term "climate zone" it is herein meant an area, in this case the electronics module, of the fuel dispenser which has an environment being controllable and favorable for the electromechanical devices comprised in this area. With this design, it is possible to provide the climate zone by adjusting the temperature of the electronics module such that it coincides with the predetermined temperature range, and thereby is favorable for the electromechanics devices comprised in the electronics module.

[0016] By the term "predetermined temperature range" it is herein meant a temperature range of the electronics module at which all, or almost all, electromechanical devices are able to operate in an efficient and secure way. If the inside temperature is outside the temperature range, the electromechanical devices may fail, or they may be a safety issue for the user or the fuel dispenser itself. By way of examples, if there are displays with touch screens, which the user may interact with, which get too hot, the user may burn its fingers or the like. The predetermined temperature range may be -60°C to +80°C, preferably -50°C to +70°C, and more preferably -40°C to +60°C. Thus, within this temperature range, the electromechanical devices may be able to operate in a desirous and secure way.

[0017] The step of providing heat to the electronics module may be conducted if the inside temperature is determined to be below the predetermined temperature range and comprises providing heat generated by a heater arranged in the fuel dispenser to the electronics module, such that the inside temperature of the electronics module is increased.

[0018] This may be advantageous as it allows for providing heat to the electronics module in an easy and efficient way, when needed, such that the climate zone in the electronics module may be provided. This may be further advantageous as it allows for providing heat to the electronics module in an easy and efficient way, when needed, such that the climate zone in the electronics module may be maintained.

[0019] The heater may be arranged in the electronics module of the fuel dispenser so as to be able to provide heat to the electronics module in an efficient way. The heater may be arranged with a temperature device which is adapted for determining the inside temperature of the electronics module. If the inside temperature is determined to be below the predetermined temperature range, the heater may be instructed to start providing heat to the electronics module so as to increase the inside temperature. When the inside temperature has reached a desired value, the heater may be instructed to stop providing heat to the electronics module. Thus, the heater may be arranged to start and stop providing heat according to predetermined temperature values.

[0020] The step of providing cooling to the electronics module may be conducted if the inside temperature is determined to be above the predetermined temperature range and comprises supplying cooling medium from a heat exchanger arranged in the fuel dispenser to the electronics module, such that the inside temperature of the electronics module is decreased.

[0021] This may be advantageous as it allows for providing cooling to the electronics module in an easy and efficient way, when needed, such that the climate zone in the electronics module may be provided. This may be further advantageous as it allows for providing cooling to the electronics module in an easy and efficient way, when needed, such that the climate zone in the electronics module may be maintained.

[0022] The cooling medium may be supplied to the electronics module via at least one cooling medium line which may be arranged to be connected to the heat exchanger, wherein the heat exchanger is adapted to supply cooling medium to the electronics module. The heat exchanger is a component which is already comprised in conventional fuel dispensers and arranged for cooling the fuel in the fuel dispenser. In addition to this, the present disclosure also uses the heat exchanger for providing cooling to the electronics module if the inside temperature is determined to be above the predetermined temperature range such that the inside temperature may be decreased. This may be advantageous as it allows for making use of components which is already comprised in the fuel dispenser in an efficient way. This is further advantageous as it allows for cooling the devices comprised in the electronics module in an easy and efficient way which in turn may reduce the risk of overheated devices as mentioned above.

[0023] The method may further comprise establishing a continuous overpressure in the electronics module.

[0024] This is advantageous in that an explosion risk of the electronics module may be reduced. Thus, by being able to establish a continuous overpressure in the electronics module, it is possible to prevent entrance of a flammable gas, vapor, dust, or fiber and thereby prevent a possible ignition. This may be referred to as a safety mechanism for the electronics module. Thus, by establishing an overpressure in the electronics module, it is created an explosion-free area, i.e. the electronics module is the explosion-free area. Thereby, reducing the risk of having an explosion in the electronics module.

[0025] This is further advantageous as it allows for providing a climate zone and an explosion-free area in the electronics module at the same time, wherein electromechanical devices may be arranged in the electronics module in a safe way.

[0026] By way of example, the overpressure may be 2-25 millibar.

[0027] The step of establishing a continuous overpressure may comprises determining an inside pressure of the electronics module; determining a surrounding pressure of a surrounding atmosphere of the electronics module; and comparing the inside pressure and the surrounding pressure and if the surrounding pressure is greater than the inside pressure, supplying a protective inert gas to the electronics module such that an overpressure in the electronics module is established.

[0028] This is advantageous as it allows for increasing the inside pressure in the electronics module, if needed, in an easy and efficient way. The protective inert gas may be compressed air. The fuel dispenser may comprise a supply line arranged to be connected to a hydrogen refueling station of the fuel dispenser which is adapted to supply the compressed air from the hydrogen refueling station to the electronics module. The compressed air is already comprised in conventional fuel dispensers in which it is used for cleansing nozzles or the like. In addition to this, the compressed air is used for increasing the inside pressure in the electronics module with this design. This may be advantageous as it allows for making use of components which is already comprised in the fuel dispenser in an efficient way.

[0029] The inside pressure may be determined by a control means. The surrounding pressure may be determined by a control means. The control means for determining the inside pressure and the surrounding pressure may be the same control means. The control means for determining the inside pressure and the surrounding pressure may be different control means.

[0030] The fuel may be hydrogen.

[0031] The fuel may be one of a Liquefied Natural Gas, LNG, Compressed Natural Gas, CNG, and Liquified Petroleum Gas, LPG.

[0032] The fuel may be gasoline.

[0033] The cooling medium may be one of liquid carbon dioxide, R449A and R452A.

[0034] R449A and R452A are cooling media well known in the art. It should however be noted that other cooling medium suitable for cooling the fuel in the fuel dispenser may be used as well. By way of example, the cooling medium may be liquid carbon dioxide or another equivalent cooling medium.

[0035] According to a second aspect of the invention, these and other objects are achieved, in full or at least in part, by a fuel dispenser for dispensing fuel to a vehicle. The fuel dispenser comprises a hydraulics module to be placed on a ground and comprising a dispensing unit connected to at least one nozzle intended to supply fuel to the vehicle, an electronics module arranged above the hydraulics module comprising dispenser electronics, a top module arranged above the hydraulics module and the electronics module, and at least one column connecting the hydraulics module with the top module.

[0036] The fuel dispenser further comprises: a temperature device arranged for determining an inside temperature of the electronics module and for comparing the inside temperature with a predetermined temperature range; a heater arranged for providing heat to the electronics module if the inside temperature is determined to be below the predetermined temperature range, such that the inside temperature of the electronics module is increased; and a heat exchanger arranged for supplying cooling medium if the inside temperature is determined to be above the predetermined temperature range to the electronics module, such that the inside temperature of the electronics module is decreased. The temperature device may be a temperature sensor arranged for determining the inside temperature of the electronics module. The temperature device may be arranged in the electronics module. By way of examples, the temperature sensor may be arranged at the heater. The temperature sensor may be arranged in vicinity to the electronics module.

[0037] The heater may be arranged with an angle so as to be able to heat the electronics module in an efficient way. By way of example, the heater may be angled 10-50 degrees, preferably 20-40 degrees, more preferably 30 degrees.

[0038] The fuel dispenser may comprise at least one cooling medium line arranged to be connected to the heat exchanger which is adapted to supply cooling medium to the electronics module from the heat exchanger.

[0039] The fuel dispenser may further comprise a control means arranged for establishing a continuous overpressure in the electronics module.

[0040] The control means may be arranged for sending an alarm signal to an operator, a PLC unit or the like if the overpressure is not able to establish. The control means may be arranged for sending an alarm signal to an operator, a PLC or the like if the overpressure is lost.

[0041] The control means may be a Ex P overpressure unit arranged to generate the overpressure in the electronics module.

[0042] The term "Ex P overpressure unit" is herein meant a pressurized enclosure type of protection which is arranged for establishing the continuous overpressure in the electronics module. The Ex P overpressure unit may comprise control and monitoring systems which are arranged for controlling and monitoring the area protected by the unit, e.g. the electronics module. The electronics module has to be a closed housing such that the continuous overpressure is able to be established. Thus, the electronics module may be Ex P classified meaning that components are protected by overpressure. Thereby, the Ex P overpressure unit is arranged to ensure that the pressure inside the electronics module is sufficient to prevent entrance of a flammable gas, vapor, dust, or fiber and prevent a possible ignition. This may be referred to as a safety mechanism for the electronics module. The Ex P overpressure unit is arranged to protect non-explosion-proof electronics in the electronics module, wherein the electronics module is arranged in a hazard area, i.e. an area which may be exposed to an risk of explosion. Thus, with this design, non- explosion protected electromechanical devices may be safely arranged in the electronics module. Other types of non-explosion protected devices may also be safely arranged in the electronics module. For there to be a risk of explosion in an area, three components must be present, namely, flammable / combustible substances, air / oxygen, and ignition source. If one of these three components is removed, the area or the component is considered an explosion-proof explosion area or an explosion-proof component. When introducing the Ex P overpressure unit, the component "flammable substances" is removed because the flammable substances may not be able to enter the electronics module due to the continuous overpressure in the electronics module.

[0043] This may be advantageous in that it allows for creating an over pressurized non-ATEX zone within the electronics module.

[0044] The fuel dispenser may further comprise at least one supply line arranged to supply a protective inert gas to the electronics module.

[0045] The protective inert gas may be compressed air. An airflow of compressed air into the electronics module may be controlled by the control means and one or more control valves comprised in the fuel dispenser.

[0046] The electronics module may further comprise at least one gauge and / or at least one sensor.

[0047] The electronics module may further comprise an outer housing, wherein at least a portion of the outer housing is provided with a window arranged to display a part of an interior of the electronics module.

[0048] This may be advantageous as it allows for monitoring the interior of the electronics module without the need of opening the electronics module. Thereby, it is possible to monitor the interior of the electronics module without a risk of losing the overpressure of the electronics module.

[0049] The window is arranged to display the control means of the electronics module.

[0050] This may be advantageous as it allows for monitoring the control means without the need of opening the electronics module.

[0051] Effects and features of the second aspect of the present invention are largely analogous to those described above in connection with the first aspect of the inventive concept. Embodiments mentioned in relation to the first aspect of the present invention are largely compatible with the further aspects of the invention. In order to avoid undue repetition, reference is made to the above.

[0052] Other objectives, features and advantages of the present invention will appear from the following detailed disclosure, from the attached claims, as well as from the drawings. It is noted that the invention relates to all possible combinations of features.

[0060] Detailed description of preferred embodiments of the invention

[0061] Fig. 1 illustrates an exemplary embodiment of a fuel dispenser 10 for dispensing fuel to a vehicle. The fuel dispensed by the dispenser described herein may be in the form of gas, liquid, or a combination thereof. By way of example, the fuel may be hydrogen, Liquefied Natural Gas, LNG, Compressed Natural Gas, CNG, and Liquified Petroleum Gas, LPG, or gasoline. The fuel dispenser 10 comprises a hydraulics module 11, an electronics module 12 and a top module 13. The hydraulics module 11 is placed on ground and has a dispensing unit (not illustrated) connected to a gas tank (not illustrated) and to at least one nozzle 14 intended to supply gas to the vehicle. The hydraulics module 11 further has one or more heat exchangers 17 which are arranged for pre-cooling the fuel during refueling of the vehicle. This may be advantageous as it prevents overheating inside the vehicle tank as well as it reduces refueling time. The heat exchanger 17 is used to transfer heat from one medium to another, i.e. in this case, the heat exchanger is used to transfer heat from the fuel to a cooling medium in the heat exchanger 17. By way of example, the cooling medium may be carbonic acid or carbon dioxide. In addition to this, the heat exchanger 17 may be arranged for supplying cooling medium to the electronics module 12 via one or more cooling medium lines 18. A cooling medium line 18 is illustrated by a dotted line in Fig. 1 and it should be understood by the skilled person that this line may be arranged in different ways as long as it is suitable for supplying cooling medium from the heat exchanger 17 to the electronics module 12. This will be discussed in more detail further below.

[0062] The electronics module 12 is arranged above the hydraulics module 11 and comprises dispenser electronics or electromechanical devices. In turn, the top module 13 is arranged above the hydraulics module 11 and the electronics module 12. As illustrated in Fig. 1, the electronics module 12 is arranged at a distance from the hydraulics module 11 and the top module 13 is arranged at a distance from the electronics module 12. As illustrated in Fig. 2, the electronics module 12 is arranged adjacent the hydraulics module 11 and the top module 13 is arranged at a distance from the electronics module 12. However, other alternatives are also possible. By way of examples, the top module 13 may be arranged directly on top of the electronics module 12.

[0063] A nozzle boot 15, adapted to hold the nozzle 14, is arranged between the hydraulics module 11 and the top module 13 on each side of the fuel dispenser 10. The nozzle boot 15 is placed directly on top of the hydraulics module 11 next to, and outside of, the electronics module 12.

[0064] A hollow column 16 connecting the hydraulics module 11 with the top module 13 is provided on each side of the fuel dispenser 10. In these types of fuel dispensers 10, it is necessary to connect the hydraulics present in the hydraulics module 11 with the electronics present in the electronics module 12.

[0065] Figs 2 and 3 illustrate an exemplary embodiment of the electronics module 12 of the fuel dispenser 10.

[0066] As best illustrated in Fig. 2, the electronics module 12 comprises an outer housing 21. The outer housing 21 may be a closed housing which has to be completely sealed. The housing 21 is equipped with a display and / or touch screen 22 and a window 23. The display and / or touch screen 22 is arranged for illustrating the refueling process to the user as well as for the user to interact with the fuel dispenser in an easy and user-friendly way. The window 23 may be a glass window and is arranged for displaying a part of an interior of the electronics module 12.

[0067] As best illustrated in Fig. 3, the electronics module 12 comprises a temperature device 31 which is arranged for determining an inside temperature of the electronics module 12. The temperature device 31 is further arranged for comparing the inside temperature with a predetermined temperature range which may be a temperature range at which the dispenser electronics comprised in the electronics module 12 may be able to operate in a desired, safe, and efficient way.

[0068] The electronics module 12 further comprises a heater 32 which is arranged for providing heat to the electronics module 12. The heater 32 may be instructed to provide heat to the electronics module 12 if the inside temperature is determined to be below the predetermined temperature range, i.e. if the inside temperature is too low compared to the predetermined temperature range. Thus, the heater 32 is arranged for increasing the inside temperature of the electronics module 12 if needed.

[0069] As said above, the one or more heat exchangers 17 of the fuel dispenser 10 may be arranged for supplying cooling medium to the electronics module 12. This may be achieved due to that the fuel dispenser 10 comprises the at least one cooling medium line 18 which is connected to the heat exchanger 17 and the electronics module 12 such that cooling medium is able to be supplied from the heat exchanger 17 to the electronics module 12. This may be provided if the inside temperature is determined to be above the predetermined temperature range, i.e. if the inside temperature is too high compared to the predetermined temperature range. Thus, the one or more heat exchangers 17 are, in addition to decreasing the temperature of the fuel, also arranged for decreasing the inside temperature of the electronics module 12, if needed.

[0070] With this design, in which the fuel dispenser 10 comprises the temperature device 31, the heater 32 and the heat exchanger 17, it is possible to provide a climate zone in the fuel dispenser 10, i.e. it is possible to provide a favorable environment for the devices comprised in the fuel dispenser 10. The climate zone is preferably provided in the electronics module 12.

[0071] The electronics module 12 further comprises a control means 34 arranged for establishing an overpressure in the electronics module 12. This may be referred to as a safety mechanism for the electronics module 12. By being able to establish a continuous overpressure in the electronics module 12, it may be possible to prevent gas from entering into the electronics module 12 from the columns 16. By way of example, the overpressure may be between 2-25 millibar. The control means 34 may be arranged for determining an inside pressure of the electronics module 12. The control means 34 may further be arranged for determining a surrounding pressure of a surrounding atmosphere of the electronics module 12. The control means 34 may be further arranged for comparing the inside pressure and the surrounding pressure and if the surrounding pressure is greater than the inside pressure, the control means 34 may be arranged to control one or more valves to supply a protective inert gas, such as compressed air, to the electronics module 12 such that the overpressure in the electronics module 12 is established. The fuel dispenser 10 may comprise a supply line (not illustrated) which is arranged to be connected to a hydrogen refueling station (not illustrated) of the fuel dispenser 10 which is adapted to supply the compressed air from the hydrogen refueling station to the electronics module 12. In addition to this, the compressed air may be used for cleaning nozzles 14 or the like in the fuel dispenser 10.

[0072] Preferably, the control means 34 is arranged in adjacent to the window 23 of the housing 21 such that it is possible to view the control means 34 without the need of opening the housing 21. In this way, it is possible to monitor the control means 34 from an outside of the electronics module 12.

[0073] The control means 34 may be an Ex P overpressure unit which is arranged for generating the overpressure in the electronics module. The Ex P overpressure unit may be referred to as a pressurized enclosure type of protection which is arranged for establishing the continuous overpressure in the electronics module 12.

[0074] Even though the method steps are described in a certain order, other orders may also be used. Although not illustrated, it should be understood by the skilled person that the electronics module may comprise further components such as valves and sensors arranged for controlling the operation of the electronics module or the electromechanical devices arranged in the electronics module.

[0075] The skilled person realizes that a number of modifications of the embodiments described herein are possible without departing from the scope of the invention, which is defined in the appended claims.
