A construction thermoacoustic partition to isolate areas from external or internal environments, refrigeration, and vehicles. The partition consists of a frame with airtightly glued insulating panels, transparent or not. If glass pane, frame, and panels are glued, they create an airtight chamber where pressure, light and solar tracking sensors are located. In its internal perimeter it has photovoltaic cells and a blind whose sheets are photovoltaic cells that make it self-sufficient in energy. The profile of the frame has channels to circulate air, where electric resistance is located, which in winter raises the temperature of the panel edges, in another, fans, temperature sensors, micro-pump, wires and reinforcements are located. The horizontal planes that create these channels have coextruded thermoacoustic bridges. It has a microprocessor with automatic or digitally modified instructions, with voice and remotely, so that components act in real time, depending to changes in the environment, which can be with Artificial Intelligence.

An air blower includes: a panel (3); a frame member (5) arranged to surround the panel (3) and having a blowout port (13a, 13b, 13c, 13d, 13e, 13f, 13g) of air formed therein; and a fan (11a, 11b, 11c, 11d, 11e, 11f, 30) that sends air to the blowout port (13a, 13b, 13c, 13d, 13e, 13f, 13g). The frame member (5) produces airflows that are blown out from at least three directions and collide with each other, thereby producing an air current going forward to the panel (3).

A shutter includes a window frame, a plurality of blade structures, an intake driving unit and an airflow guiding unit. The window frame has an upper frame portion, a lower frame portion and two side frame portions. The blade structures are disposed on the window frame, and each has a through hole and a plurality of outlets. The intake driving unit is disposed in the upper frame portion. The airflow guiding unit is disposed in at least one of the two side frame portions. Each of the through holes of the blade structures communicates with the inside of at least one of the two side frame portions.

A ventilator door brings fresh outside air into a structure through an outside opening and a fan or blower pulls outside air into a duct in the door. The air flows through the duct and into the structure through an inside grill remote from the outside opening. Heat is transferred from the flow of air to a heat sink disposed in the duct to cool the fresh air flowing into the duct. A regenerative heat sink may be used to capture heat from a flow of air from inside the structure and transfer the captured heat to a flow of outside air flowing into the structure. An inside opening in the door generally opposite to the outside opening. The air flow through the openings is controlled by movable panels by aligning or by misaligning openings in the movable panels with the openings in the outside and inside panels. A microprocessor controls the movable panels and the fan or blower in response to sensors inside and outside of the door.

A ventilated window frame comprising; a frame having a plurality of slots along an interior edge and a channel having a first opening and a second opening, a permeable layer fitted within one of the plurality of slots distal to the first edge of the frame, a permeable layer secured within one of the plurality of slots distal to the second edge of the frame, a non-permeable layer secured within one of the plurality of slots between the first and second permeable layers, wherein the first opening of the channel is between the first permeable layer and the non-permeable layer and the second opening of the channel is located between the second permeable layer and the non-permeable layer, a filter inserted within the first opening of the channel, and a fan fitted between the first opening and the second opening of the channel.

Provided is an intake-exhaust unit that easily controls the flow of air in an intermediate cavity of a double skin structure window glass, and a double skin system using the same. The intake-exhaust unit is comprised of: a first distribution port of passage of the air; a second distribution port of passage of the air, the second distribution port being separated from the first distribution port; a third distribution port of passage of the air, the third distribution port being separated from the first distribution port and the second distribution port; a fan for sending out the sucked air; a negative-pressure passage provided on the air-sucking side of the fan, the negative-pressure passage having intake holes that communicates with the first, the second, and the third distribution ports; and a positive-pressure passage provided on the air exhausting side of the fan, the positive-pressure passage having an exhaust hole that communicates with the first, the second, and the third distribution ports, wherein the air is sucked from any of the first, the second, and the third distribution ports; and the air is exhausted from any of the distribution port other than the port in use for sucking the air among the first, the second, and the third distribution ports.

A technique capable of improving power generation efficiency using a temperature difference in a partitioning member and utilizing the generated electric power for various purposes. The partitioning member includes a thermally conductive member constituting part of the partitioning member, and a thermoelectric power generation unit in contact with a part of the thermally conductive member. In particular, the thermoelectric power generation unit has a heat reception surface and a heat radiation surface, and the heat reception surface and/or the heat radiation surface is in contact with the thermally conductive member, whereby a temperature difference within the partitioning member can be efficiently utilized. In addition, the thermoelectric power generation unit may include a plurality of the heat reception surfaces and/or a plurality of the heat radiation surfaces arranged in parallel on a plane.

Various embodiments herein relate to methods, structures, tools, installation systems, etc. for retrofitting a new electrochromic window in a pre-existing window recess. In many cases, the new electrochromic window is installed parallel to a lite of a pre-existing window, with the resulting structure including the new electrochromic window, the pre-existing window, and a pocket that forms between them. Installation of a new electrochromic window in tandem with a pre-existing window results in many benefits including improved insulation (e.g., due to the presence of the additional air pocket(s) and lite(s)), improved climate control (e.g., due to the ability to control the amount of sunlight entering the building via the electrochromic window), and enhanced aesthetics.

A frame assembly for a modular window assembly for an opening in a structure comprises a main structural frame defining an electrical enclosure and being mountable to the structure, a removable exterior frame mountable to the main structural frame and defining an angled lip for water runoff, the removable exterior frame being configured to secure an outer glass pane of a set of glass panes of the modular window assembly, an insulating feature between the main structural frame and the removable exterior frame and configured to prevent thermal conduction therebetween, and at least one vapor neutralizer between the main structural frame and the removable exterior frame and configured to prevent moisture from accumulating within the modular window assembly. One primary benefit of this modular window assembly is the ability to swap out some or all of the set of glass panes and replace them with new glass technology as developed.

Disclosed is a system that utilizes at least one structural frame element within an existing aperture as a universal mounting framework for securing windows, doors and other structural elements that are installed within an existing aperture of a wall. The structural frame elements are preferably made from thermally isolating materials and are fastened within the aperture using means that do not severely damage the weather membrane. The structural frame elements may have been built in finishing trim around the installed structural components. The structural components may be further secured within the structural frame elements using holding elements and projecting members, which may be removable or unitary to the structural frame elements. Some of the surfaces of the structural frame elements that are exposed to the external environment contain a pitch that promotes drainage.
