Description

[0001] The present invention relates to a humidity control system for a hydrogen fuel cell,

The present invention relates to an indoor humidity control system for a hydrogen fuel cell vehicle.

When the air conditioner or the heater is operated with the window of the vehicle fully closed, a cold air or a warm air generated from the air conditioner or the heater absorbs or evaporates moisture in the vehicle space in a short time, thereby making the room dry.

For this reason, for example, when the car is operated for a long time with the air conditioner or heater running, the possibility of respiratory illness becomes very high and the nose is actually clogged, the skin becomes dry or a dry cough occurs.

Accordingly, in recent years, a humidifier which can be used in a vehicle has been popularly used. The humidifier for the vehicle maintains the humidity of the enclosed indoor space to some extent to protect the respirator and prevent the generation of static electricity when the vehicle is operated during the summer or winter season.

On the other hand, the most basic method of humidification in a vehicle is to use a humidifier disposed at an appropriate position in a vehicle interior. However, in this case, there is a disadvantage that the water inside the humidifier is dislocated severely depending on the vibration generated when the vehicle moves or the flow of the vehicle, and the power for operating the humidifier is supplied from the battery of the vehicle, It is not easy to fix the vehicle to the inside of the vehicle.

Japanese Laid-Open Patent Application No. 2007-062519 (a humidifying device for an air conditioner for a vehicle) discloses a technique of using moisture formed in a refrigerant pipe included in an air conditioner of a vehicle and a heat exchange fin.

As is known in the art, among the various components constituting the air conditioner, a refrigerant pipe through which the expanded low-temperature and low-pressure refrigerant flows, and a heat-exchanging pin formed outside the refrigerant pipe through the expansion valve are included. The moisture due to the temperature difference between the outside air and the refrigerant is formed on the surface of the refrigerant pipe and the heat exchange fin.

The above-mentioned prior art has a principle of using moisture formed on the surfaces of the refrigerant pipe and the heat exchange fin. That is, the moisture formed on the surface of the refrigerant pipe and the heat exchange fin is supplied to the interior of the vehicle by using a blower or the like to humidify the indoor air.

However, when the surface of the refrigerant pipe and the heat exchanging fin are contaminated, the conventional humidification apparatus has a problem that impurities are contained in the moisture formed on the surface of the refrigerant pipe and the heat exchanging fin, . The internal environment of the vehicle is rather bad.

Moreover, since moisture is not formed when the air conditioner is not used, humidification itself is impossible. It is not possible to humidify the indoor space during winter when it is necessary.

The present invention has been made in order to solve the above problems, and it is an object of the present invention to provide a hydrogen fuel cell which can recycle water generated as a result of a chemical reaction in the hydrogen fuel cell to humidify the interior of the vehicle, And an object of the present invention is to provide an indoor humidity control system for a hydrogen fuel cell vehicle which can maintain the indoor humidity appropriately and enable more comfortable driving as long as the vehicle is running.

According to an aspect of the present invention, there is provided an indoor humidity control system for a hydrogen fuel cell vehicle, including: a hydrogen tank in which hydrogen is stored; a fuel cell stack that receives hydrogen from the hydrogen tank to produce electric power; A water tank installed in a hydrogen fuel cell vehicle including a motor for receiving the electric power and rotating the wheels to maintain indoor humidity of the vehicle within a set range and storing water generated in the fuel cell stack; A humidifier disposed in an interior space of the vehicle; A water pump for pumping water contained in the water tank and supplying the water to the humidifier; A sensor unit installed in a vehicle and sensing the humidity of the room; And a control unit connected to the sensor unit and controlling the water supply pump and the humidifier based on the humidity information sensed by the sensor unit.

In addition, the vehicle interior further includes a display unit connected to the sensor unit and informing the vehicle occupant of the sensed contents of the sensor unit.

The water tank may further include a first water level sensor for sensing the amount of water stored in the water tank and transmitting the information to the controller so as to allow the controller to determine whether to operate the water pump. do.

The humidifier may further include a second water level sensor for sensing a remaining amount of water in the humidifier and transmitting the information to the controller to determine whether the humidifier and the water supply pump operate.

Further, between the water supply pump and the humidifier, And a sterilizing unit for sterilizing the water that has passed through the filter unit is further provided.

The indoor humidity control system for a hydrogen fuel cell vehicle according to the present invention as described above can recycle water generated as a result of a chemical reaction in a hydrogen fuel cell to humidify the interior of the vehicle, As long as the vehicle travels without needing to do so, the humidity of the room is appropriately maintained to enable more comfortable driving.

1 is a block diagram for explaining an overall configuration of an indoor humidity control system for a hydrogen fuel cell vehicle according to an embodiment of the present invention.

Hereinafter, one embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

Basically, the basic concept of the indoor humidity control system for a hydrogen fuel cell vehicle according to the present embodiment is that the water generated naturally during the operation of the hydrogen fuel cell vehicle is recycled and used for humidification of the room. In particular, since the indoor humidity of the vehicle is monitored in real time and the humidity is maintained within the set range, a more pleasant indoor environment can be realized.

FIG. 1 is a block diagram for explaining an overall configuration of an indoor humidity control system 31 for a hydrogen fuel cell vehicle according to an embodiment of the present invention.

As shown in the figure, the vehicle interior humidity control system 31 according to the present embodiment includes a water tank 33 for receiving and storing water generated in the fuel cell stack 13, A water supply pump 35 for supplying the water in the water tank 33 to the humidifier 39 and a water supply pump 35 for continuously sensing the indoor humidity of the vehicle. The humidifier 39 generates moisture by applying ultrasonic waves to the water, A display unit 45 for displaying the current humidity and a control unit 41 for controlling the water supply pump 35 and the humidifier 39.

The basic structure of the hydrogen fuel cell vehicle to which the humidity control system 31 is applied includes a hydrogen tank 11 fixed to a lower portion of the frame of the vehicle, (15) for receiving and converting power produced in the fuel cell stack (13), and an inverter (15) for generating a rotating torque And includes a motor 17 that generates power. The rotation torque of the motor 17 is transmitted to the wheels 19 to allow the vehicle to travel.

In the fuel cell stack 13, a coupling reaction of oxygen and hydrogen is performed within the fuel cell stack 13, and water is generated at the negative electrode according to the coupling reaction.

The water tank 33 is connected to the fuel cell stack 13 to store the water continuously discharged from the fuel cell stack 13 during operation of the vehicle .

An overflow pipe 55, which is opened and closed by a valve 53, may be installed in the water tank 33. The overflow pipe 55 is opened when the water tank 33 and the humidifier 39 are filled with water and drains the water inside the water tank 33 to the road.

A first water level sensor 51 is mounted in the water tank 33. The first water level sensor 51 checks the water level in the water tank 33 and transmits the fact to the control unit 41. The control unit 41 determines whether or not the water supply pump 35 is operated based on the information transmitted from the first water level sensor 51.

The humidifier 39 may be an ultrasonic humidifier having an ultrasonic vibrator, which is installed in an indoor space of a vehicle. The humidifier 39 can be installed, for example, behind the driver's seat, at the center of the rear seat, or under the rear glass. However, it is needless to say that the installation position of the humidifier can be variously changed according to the condition of the vehicle. In addition, the size of the humidifier can vary.

The humidifier 39 is provided with a second water level sensor 49. The second water level sensor 49 senses the water level in the self water tank provided in the humidifier 39 and sends the fact to the control unit 41 if there is no water in the humidifier 39, 41 to cause the embroidery pump 35 to operate. Or when the inside of the humidifier 39 is filled with water, the control unit 41 stops the operation of the water supply pump 35. [

The water supply pump 35 supplies water collected inside the water tank 33 to the humidifier 39 and operates by receiving power from the fuel cell stack 13 or a battery (not shown) .

The operation of the feed pump 35 is determined by the control unit 41. [ That is, it operates when receiving an operation signal from the control unit 41.

A filter unit 37 and a sterilizing unit 47 are disposed between the water feed pump 35 and the humidifier 39. The filter unit 37 serves to pass water pumped by the water supply pump 35 and to filter out various pollutants mixed in the water. The sterilizing unit also sterilizes the filtered water to remove various bacteria that may be contained in the water. Since the fine water droplets generated in the humidifier enter the respiratory system of the human body, it is very important to disinfect the sterilizing unit 47 in this way.

The sterilized water that has passed through the sterilizing unit 47 is supplied to the humidifier 39 to be filled in the tank inside the humidifier and waits to be humidified.

Meanwhile, the controller 41 may be provided with a simple switch (not shown) for simply turning the humidity control system 31 on and off by the passenger 41 of the vehicle. The switch is merely a switch for turning the humidity control system 31 on and off.

Actually, the control unit 41 has a built-in humidity range of the room, and automatically operates so as to maintain the humidity range, so that the passenger does not need to operate the water supply pump 35 or the humidifier 39 manually .

The controller 41 receives the indoor humidity information from the sensor unit 43 disposed in the interior of the vehicle, and determines whether to operate the humidifier 39. For example, when the current humidity is lower than the set value, the humidifier 39 is operated to raise the humidity.

Also, the display unit 45 displays the current humidity of the vehicle interior and notifies the occupant of the humidity. The passenger can know the current humidity in the vehicle through the display unit 45. [

The indoor humidity control system 31 for a hydrogen fuel cell vehicle having the above-described configuration is configured as follows.

First, a user who rides on the vehicle and recognizes the current indoor humidity condition through the display unit 45. When the current indoor humidity is included in the set range, the humidity control system 31 does not operate. However, if the humidity is low, the humidity control system 31 is activated through the control unit 41.

Even if the humidity control system 31 is not operated, water generated in accordance with running of the vehicle is continuously collected in the water tank 33.

The second water level sensor 49 detects the remaining water level of the water in the humidifier 39 and sends the water level to the control unit 41. [

When the water in the humidifier 39 is insufficient, the control unit 41 operates the water supply pump 35 to supply the water inside the water tank 33 to the humidifier 39. However, when it is not necessary to supply water to the humidifier 39, the control unit 41 operates the humidifier 39 and stops the water supply pump 35.

During the operation of the humidifier 39, the sensor unit 43 continuously senses the humidity of the room and transmits the humidity to the display unit 45 and the controller 41.

If the water in the water tank 33 is sufficiently collected during the above process, the water pump 35 is operated to supply the water in the water tank 33 to the humidifier 39.

If the water tank 33 is full, the humidifier 39 is opened and the water is drained through the overflow pipe 55 by opening the valve 53.

If the humidifier 39 needs to be replenished with water by continuous operation of the humidifier 39, the valve 53 is shut off and the water supply pump 35 is activated to supply water to the humidifier 39.

This operation is automatically performed by the control unit 41 that has received the water level information through the first and second water level sensors 51 and 51. [

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
