Description

  The present invention relates to a cross flow type or oblique AC type total heat exchange element that simultaneously exchanges sensible heat and latent heat by supplying fresh outside air and exhausting dirty room air through a partition membrane.

  In recent years, as the heat insulation and high airtightness of living spaces have advanced in order to enhance the heating and cooling effect, the contamination of indoor air has become a problem, and the importance of ventilation has been recognized again. As a method of performing ventilation without impairing the air conditioning effect, a method of exchanging heat between supply air and exhaust is effective. At this time, if the temperature (sensible heat) and the humidity (latent heat) can be exchanged simultaneously, the effect is remarkable. In order to meet this requirement, there is a cross flow type total heat exchanger that performs total heat exchange between supply air and exhaust gas via a partition plate (see Patent Document 1).

Japanese Patent Publication No.47-19990

As shown in FIG. 13, the conventional cross-flow type total heat exchanger uses a corrugated material 30 having a flat plate surface portion 31 and a corrugated plate surface portion 32. When the corrugated material 30 is laminated, the flat plate surface portion 31 and the corrugated plate are used. The air passages 3 formed between the surface portion 32 and the air passages 3 are alternately orthogonally crossed to circulate the supply air and the exhaust air. For example, when cold and dry outdoor air in winter is passed as supply air, and warm and humid air in a heated room is passed as exhaust air, the temperature is exchanged through the flat plate portion 31, and the supply air is warmed. Is supplied to the room. On the other hand, the exhaust is cooled and discharged outdoors.
However, in the corrugated material 30, the bonding portion between the flat plate surface portion 31 and the corrugated plate surface portion 32 is effective for sensible heat transfer but is ineffective for latent heat transfer (water vapor transmission). Therefore, the total heat exchange element constituted by the corrugated material 30 has a problem that the effective moisture permeable area in the cross-sectional area is as low as 50% to 60% and the latent heat exchange efficiency is low.

Total heat exchange elements have been proposed.
However, since the total heat exchange element that circulates two different types of air across the partition film 1 and exchanges sensible heat and latent heat in this way has an effective moisture permeable area as large as 80% or more, the latent heat exchange efficiency However, there is a disadvantage that the ability to absorb the condensation (water) generated in the air passage 25 is low.

The casing 43 is partitioned by a plurality of partition plates 47 so as to allow the total heat exchange element Z to pass through without mixing air supply and exhaust.

  As shown in FIG. 2, the total heat exchange element Z is formed in a square plate shape as a whole, and the heat exchange member 10 having a large number of parallel air passages 3... Is arranged so that the air passages 3. The crossflow type laminated body X laminated | stacked up and down is provided. Protection members 11, 11 having the same shape in plan view as the heat exchange member 10 are attached to the upper and lower end faces of the laminate X.

As shown in FIG. 3, in the use state, warm and humid exhaust air 9 at temperature T ₁ and cold and dry supply air 8 at temperature T ₃ flow into total heat exchange element Z. . In the total heat exchange element Z, the supply air 8 and the exhaust air 9 flow into the air passages 3 of the laminate X, and circulate in the laminate X so as to be alternately perpendicular to each other. The heat is transferred and the total heat exchange is performed.

If four regions respectively corresponding to the four corners A, B, C, and D of the laminate X having a square shape in plan view are assumed to be small square partition regions 6A, 6B, 6C, and 6D, one of the regions is assumed. The region (6A in the illustrated example) is close to both the intake inlet 48 where the temperature of the supply air 8 is the lowest and the exhaust inlet 50 where the temperature of the exhaust air 9 is the highest, and is adjacent to the upper and lower heat exchange members 10, The difference in temperature between the supply air 8 and the exhaust air 9 that flows between 10 becomes the largest, and the heat quantity of the heat exchange becomes the largest, and this one area is called the maximum heat exchange area M.
The small square partition regions 6A, 6B, 6C, and 6D each include four corners A, B, C, and D of the laminate X having a square shape in plan view, and the center of the opposite side of the square. It is a small square area divided into four by imaginary lines (two-dot chain lines in the figure) connected to each other.

Here, a first example of the heat exchange member 10 constituting the laminate X will be described. As shown in FIGS. 5 and 6, the first heat exchange member 10 is a plastic corrugated cardboard material 20 conventionally used. And a water absorbent pulp corrugated material 30. Specifically, the partition film 1 is provided on the window portion 4 provided in the plastic corrugated cardboard material 20 by providing the cutout portion 5 from which one corner 20a (see FIG. 12) of the square plate-shaped plastic corrugated cardboard material 20 is removed.

As another embodiment of the total heat exchange element Z, as shown in FIG. 11, it is also desirable to provide a diagonal alternating current laminate Y having a rhombus shape in plan view. The oblique alternating current laminate Y is obtained by vertically stacking rhombus-like heat exchange members 10 having a large number of parallel air passages 3 so that the air passages 3 cross each other diagonally.
In this case, four virtual rhombus partition regions 7A, 7B, 7C, and 7D are formed corresponding to the four corners A, B, C, and D of the rhombus-shaped laminate Y in plan view, The amount of heat exchanged in one region (7A in the example) is the largest, and this one region is referred to as the maximum heat exchange region M.
