The frame bars are joined to the end face plate in such a way as to be movable in the axial direction of the heat exchange element.

Heat exchanger and heat exchange ventilator

Provided is a partition plate used in a ventilator that supplies air and exhausts air at the same time. The partition plate includes: a first layer including a first porous substrate having a plurality of first pores, the first layer having a first pinhole formed by at least some of the first pores; a second layer stacked on the first layer and including a second porous substrate having a plurality of second pores, the second layer having a second pinhole formed by at least some of the second pores, the second pinhole being located at a position different from a position facing the first pinhole; and a third layer stacked on the second layer and made of a water-insoluble moisture-permeable resin.

Partition plate, total heat exchange element and total heat exchanger including partition plate, and method for producing partition plate

In a first and second corrugated portions of a first and second heat transfer plates, first front-side convex portions that are convex toward one side in a first direction and first back-side convex portions that are convex toward the opposite side in the first direction are alternately formed along a second direction. In at least one end of both ends of each of the first front-side convex portions in the second direction, a first front-side protruding portion protruding toward another first front-side convex portion is provided. The first front-side protruding portion is contactable with the second heat transfer plate. In at least one end of both ends of each of the second front-side convex portions in the second direction, a second front-side protruding portion protruding toward another second front-side convex portion is provided. The second front-side protruding portion is contactable with the first heat transfer plate.

Heat transfer plate and heat exchange element

A first passage forming member and a second passage forming member each include: a rib portion including a first wall portion constituting an end in a first direction of the first passage, a second wall portion constituting an end in the first direction of the second passage, and a third wall portion separating the first passage and the second passage adjacent to each other in a second direction from each other; a board being in contact with an end in a third direction of the rib portion, and separating a first connection passage and a second connection passage from each other; a first blocking portion installed at the end of the rib portion, to block between the first passage and the second connection passage; and a second blocking portion installed at the end of the rib portion, to block between the second passage and the first connection passage.

Heat exchanging element and heat exchange ventilator

A total heat exchange element includes partitions disposed in a state of being opposed to each other, and a spacer portion keeping a space between the partitions and forming a passage between the partitions. The spacer portion has a laminate structure in which nonwoven fabric base layers including a nonwoven fabric base material are laminated on both sides of a paper layer. A first nonwoven fabric base layer that is the nonwoven fabric base layer of the spacer portion laminated on one side of the paper layer is joined to the partition opposed to the first nonwoven fabric base layer, and a second nonwoven fabric base layer that is the nonwoven fabric base layer of the spacer portion laminated on another side thereof is joined to the partition opposed to the second nonwoven fabric base layer. The element has the above-mentioned configuration and so can improve the humidity exchange efficiency.

Total heat exchange element and total heat exchanger

A total heat exchange element includes a stacked body that is formed by alternately stacking a first layer provided with a first passage through which a first air flow passes and a second layer provided with a second passage through which a second air flow passes. The stacked body includes a partition member between the first layer and the second layer, a spacing member provided in the first layer and the second layer and maintaining a spacing between the partition members facing each other, and a latent heat shielding member provided partly on the partition member and shielding transfer of latent heat between the first air flow and the second air flow through the partition member.

Total heat exchange element, method of manufacturing total heat exchange element, and total heat exchanger

The present invention relates to a heat exchange element in which unit constituent members, each of which includes a partition member that has a heat-transfer property and a moisture permeability and a spacing member that holds the partition member with a predetermined spacing, are stacked and in which a primary air flow that passes along an upper surface side of the partition member and a secondary air flow that passes along an undersurface side of the partition member and crosses the primary air flow exchange heat and moisture through the partition member, wherein a detachment suppressing rib is provided on the opposite side of the spacing member when viewed from the partition member at a bonded portion between the partition member and the spacing member, and the partition member is sandwiched by the spacing member and the detachment suppressing rib.

Heat exchange element

Provided is a heat exchange element that suppresses an increase in air-flow resistance by suppressing deflection of a partition member caused by a change in temperature and humidity. The unit constituent members are stacked, each of which is formed of partition members that have heat-transfer properties and moisture permeability, and spacing members that hold the partition members. A primary air flow that passes along an upper-surface side of the partition member and a secondary air flow that passes along an undersurface side of the partition member cross each other so as to exchange heat and moisture via the partition member. The spacing member includes: spacing ribs that maintain the spacing between the partition members; and deflection suppressing ribs that have a height smaller than the spacing ribs so as to suppress deflection of the partition members.

Heat exchange element and air conditioner

A laminated total heat exchange element that includes a plurality of laminated plates, a first spacing member forming a first flow path between the laminated plates, and a second spacing member forming a second flow path between the laminated plates, wherein the first flow path is formed to allow fluid to pass from one side to another side of the laminated total heat exchange element, the second flow path is formed to allow fluid to pass from the another side to the one side of the laminated total heat exchange element, a third flow path, which communicates with the first flow path on the one side and extends substantially parallel to a lamination direction of the laminated plates, is formed, and a fourth flow path, which communicates with the second flow path on the another side and extends substantially parallel to the lamination direction of the laminated plate, is formed.

Laminated total heat exchange element

The present invention is a total heat exchange element in which a spacing member is provided on both sides of a sheet-like partition member to form a flow path and which performs heat exchange between an airflow that flows in a flow path formed on one side of the partition member and an airflow that flows in a flow path formed on another side of the partition member via the partition member, wherein the spacing member is molded integrally with the partition member by using a resin, and the partition member is configured to include a functional layer that has heat conductivity, moisture permeability, and gas shielding property and a heat shrink layer that shrinks at a predetermined temperature or higher.
