Description

The technical solution relates to the field of construction and can be used to increase energy efficiency in the window blocks of buildings and structures for various purposes, as well as in transport.

Known energy-active window unit (patent RU No. 86973 IPC EV 06/24, EV 3/64 publ. 09/20/2009) having at least one double-chamber glass unit and built into it, at least one heat pump module with photovoltaic converters.

The disadvantages of this energy-active window unit are its significant cost, as well as the great difficulty of replacing or repairing if the heat-transfer module fails.

The objective of the proposed utility model is the creation of a hinged translucent structure, which will serve as an effective complement to the already installed double-glazed windows to significantly improve thermal and sound insulation, prevent condensation, eliminate the expansion of broken glass fragments during accidental impacts, and also as part of the design solution in individual projects.

The specified technical problem is solved due to the fact that the window unit, which includes at least a single-chamber double-glazed window, consisting of the outer glass facing the building outside and the inner glass facing the building, is equipped with a hinged easily removable, at least one translucent element, the size of the element corresponds to the size of the lumen of the window opening , window frame or window glass, while at least two translucent elements are interconnected and have an air gap and are a hinged light a translucent structure, where their fastening is carried out both from the outer and the inner side, or between the windows of the window block, and the fastening of both the translucent element and the translucent structure is made by an easily removable or easily mounted connection.

The proposed hinged translucent design allows significantly and at minimal cost to improve the thermal and sound insulation of conventional single-chamber windows and is an effective addition to the already installed double-glazed windows, and when various types of transparent and opaque design details are applied to it, the window will look like a decorative element of the interior. With a sufficiently strong hinged translucent structure, it is possible to fasten light objects in the form of pots, shelves, hooks. Using a hinged translucent element made of a material such as monolithic polycarbonate or organic glass, it is possible to get shockproof protection of the window from accidentally hitting the ball in gyms or child care facilities, and in case of destruction it allows to exclude the scattering of broken glass fragments.

The translucent structure consists of at least two translucent elements that are fastened together by easily removable Velcro fasteners, double-sided tape, bolts, screws, buttons, hooks, magnets, etc., so that between the elements remains air gap acting as a heat insulator.

A window unit including a single-chamber double-glazed window is shown in FIG. 1. FIG. 2 shows a window unit 1, which includes a single-chamber double-glazed window consisting of an outer glass 3 facing the building outside and an inner glass 2 facing the building, and is fastened to the inner glass 2 from the outside connection 5 translucent element 4, the size of the element corresponds to the size of the lumen of the window opening. In Fig. 3, the translucent element 4 is fastened by a quick-detachable connection 5 to the inner side of the inner frame of the glass 2. In Fig. 4, to the inner glass 2 of the window unit, translucent elements 4 are fastened by a quick-connect 5 from two sides.

In experimental measurements, the temperature value for various installation of a hinged translucent element showed the results shown in table 2

The measurements were carried out using a contact thermometer of the Testo 905-t2 brand (Accuracy ± 1 (-50 ... + 99.9 ° С); ± 1% of the measured value in the remaining range Resolution 0.1 ° С The effect of sunlight, batteries, curtains, etc. is insignificant and can be neglected . Measurements made in the lower quarter of the glass.

The classic formula for calculating thermal resistance

General formula:

Where:

Rt is the thermal resistance in the thermal circuit, K / W

T2 - temperature of the beginning of the site, K (temperature in Kelvin)

T1 - temperature of the end of the section, K (temperature in Kelvin)

P is the heat flux flowing through the section of the circuit, W

where in the numerator is the difference between the temperature of the inner and outer glass.

The direct dependence of thermal resistance on the temperature balance of the glass unit is obvious. The heat saving efficiency of the hinged element can be estimated as an increase (ΔТфиг4 / ΔТфиг1-1) * 100 =%; (18 ° С / 11.5 ° С-1) * 100 = 56% on average. The effect is especially noticeable in winter frosts, when the balance between the temperature indoors and outdoors is maximum. The use of heat-reflecting film can significantly reduce the loss of radiant energy and effectively complement the hinged element.

The hinged translucent design is able to effectively deal with noise penetrating from the street and from the room. Correctly selected thickness of the translucent element and the air chamber affects the sound absorption in the entire range of acoustic frequencies and allows you to "tune" the window opening to a specific acoustic range of noise pollution. According to the current calculation practice, it is possible to assume sound insulation in the range from 3-10 decibels per one mounted element in different frequency ranges.

In the summer, when the intensity of solar radiation is maximum and a lot of excess energy gets into the premises through the windows, the need arises to protect against infrared, ultraviolet radiation and the spectrum of visible light. And here the hinged element supplemented with a heat-reflecting film can significantly reduce the costs of air conditioning. In this situation, it is more advisable to install it outside the window, this is due to a better degree of cooling of the glass surface and less energy absorption by the intermediate layers.

Adequate use of a hinged translucent element can be obtained by preventing condensation on the windows in damp rooms and in transport, especially this can be claimed in the winter, when the windows are covered with hoarfrost and become opaque.

One of the disadvantages of using multi-chamber double-glazed windows is the reduction in light transmission of the window, but this disadvantage can be minimized by reducing the thickness of the transparent elements and the use of materials with better optical properties.

The use of a hinged translucent structure or element can solve the problem of landscaping a wide range of consumers in a variety of climatic conditions.
