Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] This invention relates to a humidity-adjusted heat exchange ventilation system.

[Background technology]

Generally, in a heat exchange ventilation system, as shown in FIG. 1, a heat exchange element body 1 using lithium chloride impregnated paper as the heat exchange element 2 is used. As shown in FIG. 2, this heat exchange element body 1 allows warm air A and cold air B to flow in opposite directions with the heat exchange element 2 as a boundary.
Moisture is transferred as shown by arrow a, and heat is transferred as shown by arrow a. This type of conventional ventilation system uses a heat exchange element 2, such as lithium chloride-impregnated paper, to maintain a constant indoor humidity without letting it escape. It was not suitable for use in cold winter regions where condensation could form on the back or in the closet. As shown in FIG. 3, if a heat pipe 3 equipped with fins 3a is used as a heat exchange element, ventilation can be performed without humidity exchange. However, if humidity exchange ventilation is desired, it is necessary to It's impossible.

In Fig. 3, 4 indicates the central partition plate, and arrows A, B,
Similarly to FIG. 2, b indicates warm air, cold air, and heat exchange, respectively.

Moreover, as shown in FIG. 4, a heat exchange element 13 capable of humidity exchange, such as paper impregnated with lithium chloride, is made into a cylindrical shape.
A plurality of these are arranged in a plurality of layers at predetermined intervals in the vertical direction, and cold air B flows inside this cylindrical heat exchange element 13, and warm air flows outside the heat exchange element 13 (space above and below). There is also a heat exchange ventilation bag W10 that allows A to flow through and exchanges heat and humidity. That is, in the body] Oa of this heat exchange ventilation device 10, as shown in FIG. In addition to humidity exchange as shown in the figure, heat exchange as indicated by the arrow also occurs. In this way, passing the cold air B into the interior of the cylindrical heat exchange element 13 and passing the warm air A to the outside is achieved by the passage partitions 1 provided at both end openings of the body 10a (Fig. 4). (see). As shown in FIG. 6, this flow path partition part 1) has inlets on the left and right sides, and each opening is alternately blocked by a flow path partition plate 12 as shown in the figure to cool air B and warm air A. It is designed to separate and flow. However, since this heat exchange ventilation device 10 also performs humidity exchange at the same time as heat exchange, it is not possible to perform only heat exchange ventilation, and therefore, it has not been possible to prevent dew condensation in winter in cold regions.

[Purpose of the invention]

An object of the present invention is to provide a humidity-adjusting heat-exchange ventilation system that can selectively use two ventilation modes, humidity-exchange ventilation and dehumidification ventilation, depending on the application.

[Disclosure of the invention]

To achieve the above object, the humidity adjusting heat exchange ventilation device of the present invention includes a plurality of first air flow paths and a plurality of second air flow paths extending from one opening to the other opening in a cylindrical body.
an air flow path is partitioned by a heat exchange element capable of exchanging humidity, and a heat transfer body is inserted through the heat exchange element capable of humidity exchange, and a component of the heat transfer body is connected to a plurality of first air flows. and a second air flow path, the air flow path is located within a portion or all of the air flow path, and allows warm air to flow into the first air flow path and cool air to flow through the second air flow path from the opposite direction. The air flow path allows the user to arbitrarily select either the air blowing mode or the air blowing mode in which the cylindrical body is divided into two along the air flow direction, and warm air flows into one half and cool air flows from the opposite direction to the other half. The structure is such that a partition plate is movably provided on the body.

Next, the present invention will be explained based on examples.

FIG. 7 shows an embodiment of the invention.

In the figure, 20 is a humidity adjustment heat exchange ventilation device (hereinafter simply referred to as "heat exchange device"), 20a is its body, and 21
is the flow path partition part. 23 is a cylindrical heat exchange element made of a humidity exchangeable material such as paper impregnated with lithium chloride, and 22 is a channel partition plate provided in the channel partition section 21. As shown in FIG. 8, the flow path partition plate 22 is movably supported on both left and right sides by a central frame 24 and side frames 25, and is movable in the vertical direction. That is, by moving in the direction of the arrow from the state shown in FIG. 9, the state shown in FIG. 10 can be achieved. Furthermore, inside the body 20a equipped with the cylindrical heat exchange element 23, a heat pipe 26 equipped with fins 27 as shown in FIG. 1) is arranged in combination with the heat exchange element 23 as shown in FIG. has been done. In this case, if the fins 27 of the heat pipe 26 are located outside the heat exchange element 23 at the bottom of the body 20a,
The fins 27 are arranged so that they are located inside the heat exchange element 23 in the upper part, and vice versa, if the fins 27 are located outside the heat exchange element 23 in the upper part, they are located inside the heat exchange element 23 in the lower part. ing. 30 is a central partition plate that divides the body 2Qa into upper and lower halves. FIG. 13 shows a side view of the heat pipe 26 and the heat exchange element 23 arranged therein.

In this configuration, the flow path partition plate 22 is set as shown in FIG. 9, and as shown in FIG. When the warm air A is sent into the heat exchange element 23 in the opposite direction from the other opening, humidity exchange as shown by the arrow a and heat exchange as shown by the arrow are performed through the outer wall surface of the heat exchange element 23. In this case, heat exchange takes place primarily via the heat exchange element 23, and humidity exchange also takes place. (ii) in Figure 14.

In the heat pipes 26 (iv) and (vi), the fins 27 are connected to the heat exchange element 23 on the lower side of the body 20a.
The upper part is located outside the heat exchange element 23. On the contrary, (i), (iii), (v)
In the heat pipe 26, the fins 27 are located outside the heat exchange element 23 at the lower part of the body 20a, and are located inside the heat exchange element 23 at the upper part. When the warm air A passes through the element 23 as shown in the figure, (ii)
The heat pipes 26 of (iv) and (vi) are
The fins 27 located at the lower part of the body 20a absorb heat from the warm air A, and the upper fins 27 release the heat, thereby participating in heat exchange. The heat pipes 26 (i), (iii), and (v) do not operate because the warm air hits the fins 27 located at the top of the body 20a. Therefore, these heat pipes (i), (iii),
(iv) does not interfere with heat exchange by the heat exchange element 23.

Conversely, when warm air A passes outside the heat exchange element 23, the heat pipes 26 (i), (iii), and (v) become involved in heat exchange. In other words, if the warm air A passes through the heat exchange element 23 (or outside the heat exchange element 23), all the heat pipes 26 and their fins 27 are located inside the heat exchange element 23 at the bottom of the body 20a, If the heat pipes 26 are installed outside the heat exchange elements 23 in the upper part of the body 20a, all the heat pipes 26 will be involved in heat exchange. However, since the directions of hot air A and cold air B change in summer and winter, it is necessary to arrange the heat pipes 26 in two types of arrangement as shown in FIG. 12. The situation shown in FIG. 14 is when heat exchange ventilation is performed while exchanging humidity. Next, when you want to perform heat exchange ventilation (dehumidification ventilation) without exchanging humidity, such as when drying laundry indoors in winter in a cold region, the flow path partition part 2 of the heat exchange device 20 is used.
1 is moved from the state shown in FIG. 9 to the state shown in FIG. 10. This results in body 20
The inside of a is divided into two parts, top and bottom. In this state, as shown in FIG. 15, if warm air A is passed through the lower half of the body 20a and cold air B is passed through the upper half, heat exchange and humidity exchange by the heat exchange element 23 are not performed.
Only heat exchange by the heat pipe 26 is performed. In other words, only dehumidifying ventilation is performed, and no condensation occurs on windows or the like even when laundry is dried indoors in winter in a cold region.

Note that the flow path partition plate 22 does not slide up and down as shown in FIG.
It may be provided so as to be rotatable, and rotated as shown by arrows A and 1 in FIG. 17 to bring it into the state shown in FIG. 18. Note that, as described above, the cylindrical heat exchange element 23
Since it is not easy to position the fins 27 of the heat pipe 26 within the heat pipe, a heat pipe having a plate-shaped heat exchange element 23 as shown in FIG. 19 and saw-toothed fins 27 as shown in FIG. If 26 is combined as shown in FIG. 21, processing becomes easy. Further, as shown in FIG. 22, a heat pipe 50 having corrugated fins 51
If the heat exchange element 23 is combined with the cylindrical heat exchange element 23, the processing becomes easier. In this case, unlike the previous embodiment, the flow path partition plate 22 is arranged so as to align its longitudinal direction with the up-down direction and slide up and down, as shown in FIG. 23. Then, heat exchange ventilation and humidity exchange ventilation are performed in the state shown in FIG. 23. From that state, partition plate 2
2 into the state shown in FIG. 24, only dehumidification and ventilation will now be performed. In this device, it is not necessary to arrange the heat pipes 50 in two types of arrangement as shown in FIG. 1) and FIG. 20, so that processing becomes easy.

〔Effect of the invention〕

Since the heat exchange ventilation device of the present invention is configured as described above, the two ventilation modes of humidity exchange ventilation and dehumidification ventilation can be appropriately selected by moving the flow path partition plate provided in the flow path partition section. It becomes wet.

Therefore, when drying laundry indoors in a cold region in winter, if you switch to the dehumidifying ventilation mode, the humidity from the laundry will be discharged instead of staying indoors, preventing condensation from forming on walls and windows. . In addition, when humidity exchange is performed at the same time as heat exchange, by switching the flow path partition plate, it is possible to switch from dehumidifying ventilation to humidity exchange ventilation without excessively drying the room.
