A total heat exchange element includes a plurality of partition members made of a material that contains cellulose as a main component, a spacing member made of a material that contains cellulose as a main component, and an adhesive portion bonding the partition members and the spacing member together. The partition members are configured as flat sheets, and are stacked with a predetermined distance between them. The spacing member is disposed between adjacent ones of the stacked partition members to maintain the distance between them. The total heat exchange element has a first air flow path and a second air flow path alternately formed with one of the partition members interposed between the first and second air flow paths. The adhesive portion contains, as an adhesive component, cellulose having a smaller diameter than both of the cellulose forming the partition members and the cellulose forming the spacing member.

The present invention addresses the problem of providing a sheet for heat exchange elements, which has high water resistance, while also having excellent productivity by achieving excellent shape stability. The present invention is a sheet for heat exchange elements, which is provided with a laminate that is composed of at least a porous substrate and a resin layer, and which is configured such that the resin layer contains at least a urethane resin and a polyvinylpyrrolidone and/or a vinylpyrrolidone copolymer.

Damper device and total heat exchanger including the same

A damper device and a total heat exchanger including the same are provided in the present application, including: a damper plate, including an air port cover plate, and a rotating shaft disposed at the air port cover plate and extending along a diameter direction of the air port cover plate; and a damper plate fixing base configured to fix the damper plate inside the damper plate fixing base and including a fixing groove formed opposite to the rotating shaft and configured to fix the rotating shaft, the fixing groove including a recess disposed opposite to the rotating shaft and formed by further being recessed from at least a part of the outer circumference of the fixing groove. According to the above technical solutions of the present application, the damper device can ensure performance without reducing the air volume under low temperature conditions, and can also suppress icing of the damper device.

Air conditioning module

An air conditioning module including a thermo electric cell having a first side and a second side; an conditioning duct attached to the first side of the thermo electric cell; and an exhaust duct attached to the second side of the thermoelectric cell; wherein the conditioning duct receives and conditions air from a room, and the exhaust duct vents unwanted thermal energy.

HUMIDITY CONTROL DEVICE, METHOD OF ABSORBING AND DRAINING MOISTURE, METHOD OF GENERATING POWER, HEAT EXCHANGE VENTILATION SYSTEM, AND METHOD OF CONTROLLING HEAT EXCHANGE VENTILATION SYSTEM

A humidity control device includes a condenser and a water absorber-drainer. The condenser has a first region and a second region. The first region is a region having hydrophilicity and where moisture is condensed. The condensed moisture is moved by gravity to the water absorber-drainer via the second region. The water absorber-drainer includes a temperature control member and has a water absorption surface and a water drainage surface. When a temperature of the water absorber-drainer is in a first temperature region, the water absorber-drainer absorbs through the water absorption surface the moisture moved from the condenser. When the temperature of the water absorber-drainer is controlled to be in a second temperature region by an operation of the temperature control member, the water absorber-drainer drains the absorbed moisture through the water drainage surface.

PLATE PACKAGE, PLATE AND HEAT EXCHANGER DEVICE
20220003505 · 2022-01-06 · ·

A plate package for a heat exchanger device includes a plurality of heat exchanger plates with mating abutment portions forming a fluid distribution element in every second plate interspace thereby forming in the respective second plate interspaces two arc-shaped flow paths wherein a respective one of the two flow paths is divided into at least three flow path sectors arranged one after the other along a respective flow path. A plate and a heat exchanger are also disclosed.

Recuperator

A recuperator including neighbouring sheets between which flow passages for air are formed. The sheets are provided with a corrugated profile including peaks, troughs and straight flanks. The peaks and troughs of a sheet are situated at an equal distance from a central plane of the sheet. Neighbouring flanks are directly connected to each other via a peak or trough. Between neighbouring flanks, first and second passage duct parts are formed which are each delimited at one end by a peak or trough and which are open at the end situated opposite the peak. In a direction at right angles to the central plane, the peaks and troughs associated with neighbouring sheets are aligned with respect to each other in such a way that first passage duct parts of a sheet and second passage duct parts associated with a neighbouring sheet are in communication with each other via connecting passage parts which extend between the troughs associated with the one sheet and peaks associated with the other sheet. The first passage duct parts, the second passage duct parts and the connecting passage parts between two sheets together form a flow passage. The smallest distance between the respective peaks and troughs which define the connecting passage parts is greater than 40% of the distance between neighbouring flanks.
