In addition, an air discharge pipe (hereinafter, referred to as a “first air discharge pipe”) 141 for air discharge to the outside is connected to the rear surface of the main body 100.

Of course, each of the air inlet 110, the air outlet 120, the respective air discharge holes 131 and 132, and the first air discharge pipe 141 may be formed or installed in other portions of the main body 100.

In addition, each of the reactors 210 and 220 is mounted at the central portion of the main body 100 with spaces partitioned from each other.

The reactors 210 and 220 generally include a plurality of reaction vessels (not shown) formed by filling hydrogen storage alloys and hydrogen outlet pipes (not shown) through which inflow and outflow of hydrogen is performed, thereby serving as a heat exchanger. do.

That is, when hydrogen is introduced into the reaction vessel, an exothermic reaction is performed to heat the surrounding air, and when hydrogen is released to the outside of the reaction vessel, the endothermic reaction is performed to cool the surrounding air.

In addition, the hydrogen flow path tube 300 is formed so that both ends are in communication with each of the reactors 210 and 220, respectively, and the other from the one reactor (hereinafter referred to as "the first reactor") 210 It serves to guide the hydrogen flow to the reactor (hereinafter referred to as "second reactor") 220.

In addition, the pumping means 400 is installed on the pipeline of the hydrogen flow path tube 300, and serves to forcibly transport the hydrogen flowing in the hydrogen flow path tube 300 from one reactor to another. .

In this case, the pumping means 400 may be a conventional pump or compressor, but is not limited thereto.

The blowing means 500 is installed between the flow path between the reactor and the space in which the air discharge holes 131 and 132 are formed.

That is, by installing the upper and lower sides of the main body 100, the external air is forced to blow through the respective reactors (210, 220) to be heat-exchanged, and the heat-exchanged air is blown to be discharged to the room or the room. .

In addition, the air flow guide means is provided between each of the reactors 210 and 220 to partition the spaces in which the respective reactors 210 and 220 are mounted.

In particular, the air flow guide means includes a switch plate 610 that rotates with respect to the center side between each of the reactors 210 and 220, and a drive motor 620 axially coupled to rotate the switch plate 610. It is composed.

Therefore, the air passing through each of the reactors 210 and 220 by the rotation of the switching plate 610 may be selectively flow toward the indoor or outdoor side.

In addition, the humidifying unit is installed on the upper end of the main body 100, and performs a humidifying operation using heated air in the heat-exchanged air while passing through each reactor.

The humidifying unit includes a storage tank 710, an air flow unit 720, and a humidifying air discharge unit.

At this time, the storage tank 710 is stored in the water, and has an inlet 711 through which water is supplied and a humidified air discharge hole 712 through which humidified air is discharged.

In addition, the air flow part 720 communicates with the second air discharge hole 132 of the main body 100 to serve as a passage for supplying heat exchanged air to the reservoir 710.

In particular, the first air discharge pipe 141 connected to the rear surface of the main body 100 is positioned to communicate with the space in which the reservoir 710 is provided so that heated air heated in the reservoir 710 may be discharged to the outside. Make sure

At this time, the first air discharge pipe 141 is a pipe opening and closing means (hereinafter referred to as "first pipe opening and closing means") to allow the pipe to be selectively opened and closed and to control the amount of opening and closing (150) ) Is provided.

This is to allow the discharged heating air to flow in the space provided with the storage tank 710 so that the heating tank 710 can sufficiently heat the discharge tank.

The first pipe opening and closing means 150 only needs to be made of a configuration in which the degree of opening and closing of the pipe line can be adjusted to a desired degree by electrical control.

In particular, in the embodiment of the present invention, the opening and closing plate 151 and the opening and closing plate 151 which is rotatably mounted on the communication site with the first air discharge pipe 141 and the first pipe opening and closing means 150, It is proposed to include a rotary motor 152 to selectively rotate.

In addition, the humidifying air discharge means constituting the humidifying portion is composed of a fan 730 so that the humidified air can be smoothly discharged to the room.

In this case, a humidifying air outlet 740 is formed at an adjacent portion of the fan 730, which is the front surface of the humidifying unit, for indoor discharge of humidified air forcedly blown by driving of the fan 730.

The configuration for the humidification operation as described above is to reduce the manufacturing cost and power consumption by using waste heat instead of the heater that was used for the normal humidification operation.

Hereinafter, with reference to Figures 1 to 4 showing the operation of the humidification combined heating and cooling device according to the present invention configured as described above will be described later.

First, if the cooling operation of the room is performed, while the pumping means 400 is operated by the control of a controller (not shown), hydrogen is desorbed from the inside of each of the reaction vessels of the first reactor 210 and the respective reactions of the second reactor 220 are performed. Forced pumped into the vessel.

In this process, the first reactor 210 undergoes an endothermic reaction due to hydrogen hernia, and the second reactor 220 performs an exothermic reaction due to occlusion of hydrogen.

In addition, each blowing means 500 is also operated under the control of the controller to forcibly blow the indoor (or outdoor) air to each reactor to be heat exchanged.

Therefore, the indoor air is introduced into the main body 100 through each air inlet 110 formed at both sides of the main body 100 and simultaneously exchanges heat through the reactors 210 and 220.

At this time, the air passing through the first reactor 110 of the forced air is cooled by the endothermic reaction of the first reactor 110, the air passing through the second reactor 120 is the second reactor Heated by an exothermic reaction of 120.

Thereafter, the heat-exchanged air is discharged according to each need.

At this time, the discharge direction of the heat-exchanged air is determined by the switching plate 610.

For example, when the air conditioner is operated in the cooling mode, the switch plate 610 is switched such that the space provided with the first reactor 210 performing the endothermic reaction communicates with the first air outlet 121.

In this case, since the space in which the first reactor 210 performs the endothermic reaction is in communication with the first air discharge hole 131 as shown in FIG. 2, the air cooled while passing through the first reactor 210. Is passed through the first air discharge hole 131 is discharged into the room through the air outlet 120 formed in the main body 100.

In addition, since the space provided with the second reactor 220 performing the exothermic reaction is in communication with the second air discharge hole 132, the air heated while passing through the second reactor 220 discharges the second air. The air flow portion 720 flows through the ball 132, and the heated air is discharged to the outside through the first air discharge pipe 141.

At this time, the first pipe passage opening and closing means 150 provided in the first air discharge pipe 141 enables smooth discharge of the heating air by making the communication part of the first air discharge pipe 141 completely open. .

If the user selects the humidification operation to be performed during the series of processes as described above, the controller controls the rotating motor 152 constituting the first pipe opening and closing means 150 to rotate the opening and closing plate 151. 1 closes the air discharge pipe (141).

At this time, the first air discharge pipe 141 may be in a completely closed state, but the air heated in the storage tank 710 may be discharged by making a part of the first air discharge pipe 141 open. More preferably, the load on the air flow due to the closing of the discharge flow path can be prevented.

In addition, the water stored in the reservoir 710 during the above process is heated by the heating air while the vaporized humidified air in the body 100 through the humidifying air discharge hole 712 formed in the reservoir 710. It is discharged to the upper space.

In this case, considering that the fan 730 constituting the humidifying air discharge means is provided at a portion where the humidified air discharge hole 712 is formed, the humidified air is driven on the front surface of the humidifier by driving the fan 730. The room is humidified by being discharged into the room through the formed humidifying air outlet 740.

In addition, the controller counts the reaction conversion cycles of the reactors 210 and 220 while the above-described series of processes are performed.

In order to prevent deterioration of the second reactor 220 that is exothermic in each of the reactors 210 and 220, it should be changed to perform an endothermic reaction before the second reactor 220 is deteriorated.

In particular, the reaction conversion cycle is confirmed by measuring the temperature of each of the reactors 210 and 220 after preliminarily setting the time or counting the reaction allowable temperature of each of the reactors 210 and 220 in advance.

If, by the above process, the reaction switching time of each of the reactors 210 and 220 is controlled, the controller controls the pumping means 400 to drive the hydrogen in the second reactor 220 to be pumped to the first reactor 210.

Accordingly, the hydrogen in the second reactor 220 is pumped to the first reactor 210 through the hydrogen flow path tube 300, in which the hydrogen storage alloy of the second reactor 220 is discharged of hydrogen In addition to performing the endothermic reaction according to the hydrogen storage alloy of the first reactor 210 performs an exothermic reaction according to the inflow of hydrogen.

In addition, the controller controls the driving motor 620 to change the flow direction of air by rotating the switch plate 610.

That is, the switch plate 610 is rotated in the clockwise (or counterclockwise) direction as shown in FIG. 3 while the space provided with the first reactor 210 communicates with the second air discharge hole 132. In addition, the space provided with the second reactor 220 is to communicate with the first air discharge hole (131).

Therefore, the flow direction of air is changed by the above-described series of processes.

That is, the space provided with the first reactor 210 communicates with the second air discharge hole 132 by the rotation of the switching plate 610, and the space provided with the second reactor 220 discharges the first air. It is in communication with the ball (131).

In addition, since the driving of the blowing means 500 is continuously performed during this process, the air flows through the first reactor 210 of the air introduced into the main body 100 through each air inlet 110. The heated air that is heat-exchanged is discharged to the space where the air flow unit is connected through the second air discharge hole 132, and the cooling air that is heat-exchanged while passing through the second reactor 220 is indoors through the first air discharge hole 131. Discharged.

At this time, the operating state of the humidifying unit is the same as described above.

Therefore, the smooth cooling operation and humidification operation of the room can be made continuously.

On the other hand, the present invention is not limited to that can be configured so that the humidification operation is performed only when the room is simply cooled.

That is, considering that the indoor heating operation is performed in the dry winter season, it is more preferable to enable the humidification operation even during this heating operation.

Therefore, another embodiment of the present invention further proposes a series of configurations that enable the humidification operation not only in the cooling operation but also in the heating operation.

That is, as shown in FIG. 5, the space in which the first air discharge holes 131 are formed is further communicated with the space formed by the air flow unit 720.

In particular, in the present invention, by allowing the respective spaces to be selectively communicated or blocked, the humidification operation is possible regardless of the cooling operation and the heating operation.

This is possible by forming a communication hole 160 in the wall surface of the space where the respective spaces meet, the communication hole 160 is provided with a pipe opening and closing means (hereinafter referred to as "second pipe opening and closing means") (170). Do.

In addition, in the above-described configuration, the cooling air discharged through the second air discharge hole 132 does not flow to the installation position of the humidifying part so as to be located at the bottom side of the main body 100 in the flow path of the air flow part 720. Connected through a separate air discharge pipe (hereinafter referred to as "second air discharge pipe") (142).

At this time, the second air discharge pipe 142 is further provided with a separate pipe opening and closing means (hereinafter referred to as "third pipe opening and closing means") 180.

In such a configuration, if the heating operation of the room is performed, the third pipe opening / closing means 180 opens the second air discharge pipe 142 and at the same time closes the pipe of the air flow part 720 to cool the air. Do not flow into the installation space of the humidifier.

In addition, the second channel opening and closing means 170 opens the communication hole 160 so that the space in which the first air discharge hole 131 is formed and the space formed by the air flow part 720 communicate with each other.

Therefore, the heated air that is heat-exchanged while passing through each of the reactors 210 and 220 passes through the first air discharge holes 131 to be discharged into the room through the air outlet 120 formed in the main body 100, and a part of the heated air is discharged into the room. It flows along the air flow part 720 through the communication hole 160 formed on the conduit between the air discharge hole 131 and the air outlet 120.

At this time, the heated air flowing through the air flow unit 720 heats the reservoir 710 to evaporate water in the reservoir 710, and the evaporated humidified air is a humidified air discharge hole 712 and humidified air. Passed through the outlet 740 in sequence to be discharged into the room.

In addition, the cooling air heat-exchanged while passing through each of the reactors 210 and 220 passes through the second air discharge holes 132 and flows through the air flow part 720.

At this time, the cooling air flowing through the air flow portion 720 is moved to the outside through the second air discharge pipe 142 by the third pipe opening and closing means 180 provided on the pipe of the air flow portion 720. Discharged.

Of course, if the reaction of each of the reactors 210 and 220 is switched, only the switching plate 610 is rotated so that the heating air is continuously discharged through the first air discharge hole 131 and through the second air discharge hole 132. Cooling air can be discharged.

Therefore, the humidification operation of the humidifying unit is continuously made.

If the humidification operation is interrupted, the second channel opening / closing means 170 provided in the communication hole 160 closes the communication hole 160 while operating under the control of the controller. Not done.

As described above, the humidification combined use air conditioning apparatus using the hydrogen storage alloy according to the present invention has the effect of being able to perform the operation as a humidifier as well as performing the operation as an air conditioner.

In particular, the heating air for performing the operation to the humidifier is not required to add an additional configuration, such as a heater or the like by using the heating or cooling air used during heating and it is possible to reduce the power consumption due to the additional configuration Has an effect.
