The embodiments of the invention relate to a transparent panel or window insert of corresponding shape and size to a casement or awning window. The transparent panel or window insert is attached to the frame of a casement or awning window or an insect screen by way of a series of releasable fasteners around the outer perimeter of the transparent panel or window insert. A void, corresponding to the shape and size of a A/C hose is cut into the transparent panel or window insert. In some embodiments of the invention the void may be bayoneted to cooperate with bayonette-style hose connections.

A protective screen system and method of installation for preventing bugs and insects from passing through a door or window opening, as well as preventing pets, such as dogs and cats from causing damage to a protective screen. The system and method include removing an existing screen from a door or window frame and inserting a protective screen member through a front face of the frame. The protective screen member is a rigid, transparent panel having a plurality of spaced apertures forming a grid pattern. The protective screen member is positioned through an opening of the frame and within a groove thereof such that an entire outer perimeter of the protective screen member is seated within the door or window frame. The protective screen member is secured to the frame via application of a fastener such as an adhesive or tape.

Glass buildings are characterized by contradictory requirements—high visibility and high insolation levels. Transparency will allow sun radiation into the building, while isolation will prevent heat to be ventilated through same windows. This creates a greenhouse effect during summer, leading to excessive air conditioning load. As a result, leading architects and engineers are calling for all-glass skyscrapers to be banned. The disclosed art offers an alternative glass envelope which adapts its U-Value to climate changes, by a special aluminum frame which dissipates the heat when necessary. The proposed system is sealed and the adaptation of the envelope U-Value is achieved by circulating enclosed air into the aluminum frame, significantly increasing its heat dissipation characteristics. The disclosed art overcomes most drawbacks of prior art, offering a solution with superior U-value isolating during wintertime and cooling during summertime. SHGC will be controlled by a triple glazed configuration with two parallel cavities.

Method and apparatus for ventilating an interior space, such as a large industrial structure with at least one bay opening. A ventilation system includes an array of M by N fans stacked into a two dimensional (2D) array. A rigid frame supports the array. A seal assembly provides a nominally fluid-tight seal between an outer perimeter of the array and the bay opening. A locking assembly mechanically couples the frame to the bay opening. In some cases, a bay door can be partially retracted and attached to a top of the frame. In other cases, the bay door may be fluidically permeable (e.g., a chain, a screen, etc.) and the array is secured behind a fully closed door. Cooling air is directed out the bay opening at a suitable time, such as overnight. A soft-start motor capability can be used to initiate operation of the array.

The present invention relates to an air-conditioning device comprising: a case having an interior divided into a first area and a second area, having an indoor inlet and an indoor outlet formed therein such that the first area and an indoor space communicate with each other, and having an outdoor inlet and an outdoor outlet formed therein such that the second area and an outdoor space communicate with each other; a barrier arranged between the first area and the second area inside the case; an indoor blowing fan arranged in the first area so as to form a flow of air from the indoor inlet to the indoor outlet; an outdoor blowing fan arranged in the second area so as to form a flow of air from the outdoor inlet to the outdoor outlet; a first thermoelectric element comprising a first indoor heat exchanger arranged in the first area so as to exchange heat with air passing through the first area, and a first outdoor heat exchanger arranged in the second area so as to exchange heat with air passing through the second area; a case lower-surface formed on the lower surface of the case so as to have an open upper side such that condensed water generated from the first thermoelectric element is collected; and a second thermoelectric element arranged between the first thermoelectric element and the case lower-surface so as to heat the condensed water. The first area and the second area are connected between the case lower-surface and the second thermoelectric element such that the condensed water is distributed across the first area and the second area. The present invention is advantageous in that indoor cooling/heating can be performed without no separate compressor, outdoor unit, and the like, and condensed water can be effectively evaporated.

The invention belongs to the devices for automatic cleaning and ventilation of windows from the facade of high-rise buildings. The technical result of the proposed invention is the simplification of the construction of the device, which makes it possible to clean the glass surface without human resources, which is also financially profitable. In this case, the glass cleaning, which is carried out by a climber and costs from 7 to 28 dollars per square meter, is reduced to 1 dollar per square meter through the proposed invention. The essence of the invention lies in the fact that the proposed device contains an additional washing solution valve equipped with pipes, ventilation box, ozonator, filters, speakers and control panel, water valves, as well as a water valve with a flushing solution for the pipe. In the first section of the frame, the water valve is also connected to the outlet pipe.
