Description

Rotary Heat Exchanger {ROTARY TYPE HEAT EXCHANGER}

The present invention relates to a rotary heat exchanger, and to a rotary heat exchanger capable of semi-permanently using a heat exchange medium and improving heat exchange efficiency.

As the issue of energy depletion is on the rise, research and development on energy saving methods are being actively conducted.

As part of this, the heat exchanger is installed in the air conditioning system to save the energy required for heating and cooling of the building.The heat exchange between the indoor air discharged from the inside of the building and the outdoor air introduced from the outside of the building There are an increasing number of examples of how this is done.

Various types of heat exchangers are used. Among them, a portion of the heat exchange drum containing the heat exchange medium allows air to flow out to the outside, and the remaining portion of the heat exchange drum allows air to flow into the room. In addition, a rotary heat exchanger is widely used such that heat exchange occurs between the air flowing into the outside and the air flowing into the room by allowing the heat exchange drum to rotate.

In general, since a porous filter is used as the heat exchange medium of the drum, foreign matter contained in the air discharged to the outside of the building and the air introduced from the outside after circulating the room is easily deposited on the heat exchange medium of the heat exchange drum.

Since these foreign substances often contain bacteria or mold spores, there is a frequent occurrence of contaminated air into the interior of a building due to mold infestation or growth of bacteria in heat exchange media.

In addition, when a large amount of foreign matter is deposited on the heat exchange medium, the ventilation of the heat exchange medium is significantly lowered, which may result in inadequate ventilation. In particular, an area in which air contains a large amount of dust or a yellow dust phenomenon frequently occurs. In the season this phenomenon occurs more frequently.

In order to solve these problems, the process of separating the heat exchange medium from the rotary heat exchanger, replacing it with a new one, removing foreign matters, and then reassembling it repeatedly has to be carried out. The disadvantage is that it takes time.

Meanwhile, the heat exchange medium 38 has a granular shape as described above, and may be manufactured to have a spherical outer circumferential surface using a metal or a thermally conductive rubber as a material. Although not shown, a space may be formed inside the heat exchange medium 38, and the space may be filled with air or a large heat insulating material. This is to allow the heat exchange medium 38 to easily exchange heat with the air A1, A2, B1, B2 passing through the rotary heat exchanger 1.

4 to 9 are views for explaining the operation of the rotary heat exchanger according to an embodiment of the present invention. The operation of the rotary heat exchanger 1 according to the embodiment of the present invention having the structure as described above with reference to FIGS. 4 to 9 will be described.

Referring to FIG. 4, the heat exchange drum 30 is rotated by the rotation of the drum driving roller 362. At this time, the plurality of openings 333 are all covered by the ring-shaped cover 35, and the cover opening and closing roller 372 is separated from the ring-shaped cover 35.

Accordingly, as described with reference to FIG. 1, heat exchange between air (A1, A2, B1, B2 in FIG. 1) passing through the rotary heat exchanger 1 by the heat exchange medium 38 in the heat exchange drum 30 is performed. Is done.

That is, the air A1 and B1 introduced into the heat exchange drum 30 exchange heat with the heat exchange medium 38 in the course of passing through the heat exchange drum 30.

For example, after heat exchange is performed between the air B1 flowing from the outside of the building and passing through the heat exchange drum 30 and the heat exchange medium 38, the heat exchange drum 30 is rotated to position the heat exchange medium 38. The heat exchange medium 38 is exchanged with the air (A1) flowing out from the interior of the building and passing through the heat exchange drum 30 as it is changed.

This action is made continuously according to the rotation of the heat exchange drum (30).

On the other hand, foreign matter contained in the air (B2) flowing from the outside of the building may be removed by the heat exchange medium 38 in the process of passing through the heat exchange drum (30).

This is because air (B2) is passed through a highly complex gap formed between the plurality of granular heat exchange medium (38), so that a large number of foreign matter is separated from the air (B2) flowing in this process.

In addition, as the heat exchange drum 30 is rotated, the heat exchange media 38 filled therein collide or rub against each other in a plurality of receiving spaces formed in the heat exchange drum 30. As described above, since the heat exchange medium 38 is made of metal or conductive rubber, static electricity may be generated between the heat exchange medium 38.

Therefore, the foreign matter contained in the air B2 flowing from the outside of the building is adsorbed by the heat exchange medium 38 in a state of being charged by the static electricity described above.

Although not shown, a charging means for charging the heat exchange medium 38 may be further installed in the heat exchange drum 30 in order to further increase the effect of adsorbing foreign matter on the heat exchange medium 38. Means for charging the static electricity to the conductor is well known, so the description of the charging means itself is omitted.

For reference, as the diameter of the heat exchange medium 38 decreases, the contact area between the air B2 and the heat exchange medium 38 increases, so that the heat exchange medium 38 may be manufactured to have the smallest diameter possible.

As described above, the amount of foreign matter adsorbed on the heat exchange medium 38 is increased in the course of the heat exchange between the air A1 and B1 passing through the heat exchange drum 30. When a large amount of foreign matter is adsorbed on the outer circumferential surface of the heat exchange medium 38, the contact area with the air is reduced, so that the heat exchange efficiency and the effect of removing the foreign matter are also lowered.

Foreign matter adsorbed on the heat exchange medium 38 is removed through the following process.

First, the drum driving roller 362 is rotated so that any one of the plurality of openings 333 is positioned above the inlet 132, and then the drum driving roller 362 is stopped so that the heat exchange drum 30 is no longer rotated. To be fixed.

In this case, in order to detect that any one of the plurality of openings 333 is positioned above the inlet 132, the angle at which the heat exchange drum 30 is rotated should be grasped. Therefore, although not shown, an angle sensor capable of measuring the rotation angle of the heat exchange drum 30 may be installed in the heat exchange drum 30 or the drum driving means 361.

Thereafter, the cover opening and closing roller detaching means (373 of FIG. 3) is driven to move the cover opening and closing roller 372 in the direction of the arrow shown in FIG. 4 to contact the ring-shaped cover 35.

Referring to FIG. 5, after the cover opening and closing roller 372 is in contact with the ring-shaped cover 35, the cover opening and closing roller 372 is rotated so that the ring-shaped cover 35 is relatively rotated with respect to the rim 33. At this time, since the rim portion 33 is fixed by the drum driving roller 362, the ring-shaped cover 35 can be easily rotated relative to the rim portion 33 in accordance with the rotation of the cover opening and closing roller 372.

When the ring-shaped cover 35 is rotated so that the through hole 353 overlaps the opening 333 positioned above the inlet 132, the heat medium means 38 filled in the receiving space in communication with the opening 333 is applied to gravity. It flows out of the heat medium drum 30 by this.

The heat medium means 38 flowing out of the heat medium drum 30 flows into the washing chamber 13 through the inlet 132.

Referring to FIG. 6, after the heat medium means 38 enters the washing chamber 13, the opening and closing valve 134 is opened to allow the washing water 79 to flow into the washing chamber 13 through the water supply pipe 133.

Thereafter, the stirring means 70 is operated to stir the washing water 79 so that foreign matter adsorbed on the outer circumferential surface of the heat medium means 38 is removed from the heat medium means 38. In this case, since the heat medium means 38 should be able to be easily flowed together with the washing water 79 in order to increase the washing effect, the heat medium means 38 may be manufactured such that its specific gravity is equal to or smaller than water.

For reference, although not shown, when the space inside the washing chamber 13 is sufficient, any of the processes described with reference to FIGS. 4 and 5, that is, one of the plurality of openings 333 may be disposed on the inlet 132. By repeating the process of positioning and rotating the ring-shaped cover 35 with the cover opening and closing roller 372 so that the heat medium means 38 is introduced into the inlet 132, all the heat medium means (38) in the heat exchange drum (30) ) May be introduced into the washing chamber 13 to be washed.

Referring back to FIG. 6, the wash water 79 continues through the water supply pipe 133 to prevent foreign matter contained in the wash water 79 from being resorbed to the heat medium means 38 while the heat medium means 38 are washed again. At the same time, the opening / closing valve 136 may be opened so that the amount of the washing water 79 supplied to the washing chamber 13 may be drained through the drain pipe 135.

For reference, in the process of stirring the washing water 79, the plurality of heat exchange media 38 may frequently collide or rub against the blade 72. In order to prevent the heat exchange medium 38 from being damaged by such a collision or friction, the blade 72 may be made of a synthetic resin having elasticity and flexibility, or coated with a material having elasticity.

After the washing is completed, the operation of the stirring means 70 is stopped and the washing water 79 is discharged through the drain pipe 135. At this time, although not shown, a filter may be attached to the end of the drain pipe 135 so that the heat medium means 38 is not discharged together with the washing water 79 through the drain pipe 135.

After the washing water 79 is discharged through the drain pipe 135, the opening / closing valves 511 and 512 installed at both ends of the transport pipe 51 are opened, and then the transport means 53 is operated, as shown in FIG. 7. The heat medium means 38 is allowed to flow to the drying chamber 15. Referring to FIG. 7, the heat medium means 38 is moved to the drying chamber 15 by the transfer means 53.

At this time, the bottom surface of the washing chamber 13 is inclined downward toward the portion to which the conveying tube 51 is connected so that the heat medium means 38 in the washing chamber 13 can be easily moved through the conveying tube 51. Can be formed.

After all of the heat medium means 38 are transferred to the drying chamber 15, the operation of the on / off valves 511 and 512 and the transfer means 53 is stopped. Thereafter, the intake fan 156 is operated to allow air outside the housing 10 to flow into the drying chamber 15, and the introduced air flows out of the housing 10 through the exhaust port 157.
