DE2842465A1 - Multi glazed window or wall heat flow control - involves regulator linked to enclosed sensors conveying heat and removing moisture - Google Patents

Abstract

The system provides reduction of heat passage through multi-paned window surfaces and layered glass walls, to save energy. The spaces between panes are filled pref. with non-circulating quantities of air. Temperature and moisture sensors are fitted in these spaces, connected to a control and regulating appliance. This conveys heat energy to the air or gas, via heating elements and pipe ducts. If moisture has penetrated, it removes this by an air or gas exchange process, pref. carried out intermittently. Electric heating wires may be used to supply energy to the enclosed gas. Heavy solid materials, as well as porous ones, can be used for heat insulation.

Description

multi-pane windows and assimilated

Surface elements with regulated heat transfer "The invention relates to the reduction in heat transfer through window surfaces and multi-layer glass walls.

In addition, the invention relates to the regulation of the heat transfer through multi-shell surface elements made of porous and heavy building materials as well as the Regulation of the moisture content of these elements in the interests of prevention Damage caused by moisture and the avoidance of misted window panes.

It is known that an amount of heat enclosed in a room The most effective way to protect against energy loss is when this amount of heat is enclosed by a layer of air at rest. and this or several Enclosing layers of air are constantly at the same level thanks to regulated energy supply set temperature can be maintained.

Nature uses this principle of action.

A space-enclosing layer of air is housed in the fur of the animals is kept at a constant temperature by body heat.

It is currently common practice to use porous materials for thermal insulation a standing volume of air that obstructs the passage of heat.

The heat loss through window surfaces and glass walls is unsatisfactory and surface elements made of heavy, non-porous building materials. The information leaflet of the Federal Minister for Economic Affairs - Energy Saving in Building and Housing shows extent 37% of the heat losses in a single house go through the windows. (Elsnerdruck-KG, Berlin).

The invention is therefore based on the problem of the passage of heat and moisture through windows and equivalent multi-shell surface elements made of heavy and / or light porous building materials within wide limits in the sense of a minimization of energy losses to influence an amount of heat enclosed in a room.

This object is achieved according to the invention in that windows, glass walls, vertical and horizontal surface elements are multi-layered and between The disks or shells of the elements arranged stationary gas or air quantities will. Through the supply of energy, the heat losses of the enclosed Gas or air volume added continuously or intermittently. about exchanging the Trapped air can penetrate moisture or can be fogged Window panes are eliminated.

Preferably, in the spaces between the shells of the surface elements ( e.g. between the window panes) temperature sensors are arranged which are connected to a control unit that the heat supply in the spaces between the panes regulates and regulates air exchange when moisture has penetrated again can be appeased.

According to the invention, the spaces between the windows or surface elements Heated by electrical heating wires, heat conducting pipes or an infeed Hot air or gas flow. The positively controlled air or gas exchange takes over according to the invention the removal of moisture from the elements0 The advantage of the solution is that the temperature gradient in the multi-layered windows and surface elements is like this lets control the amount of heat trapped in a room no Energy losses suffer because the surrounding air gap is forced to regulate and can have the same temperature as the interior. Since the gas volume is between If the panes have little or no air circulation, they are closed additional energy losses and the heat transfer through multi-layered window elements is minimized.

As a rule, there is no need for vacuum spaces between the panes will. The usual vacuum windows, however, increase the heat-insulating effect of the compulsorily controlled multi-layer windows or surface elements.

The advantage of the solution is that the heat can pass through window-glass walls or equivalent multi-shell surface elements by supplying heat energy into them Surface elements can be largely influenced. The advantage of the solution is that Not only can porous building materials be used for thermal insulation, but also heavy, dense materials.

The thermal insulation is here the enclosed standing Lutt or Gas layers are assigned, while the element shells consist of glass or steel can. Since there is no air circulation, the trapped air layers are in place a high heat transfer resistance and only require a low level of additional Heat supply ', the amount of heat trapped in a house or in a room to protect against losses.

The advantage of the invention is that the energy demand is regulated The heating of the window or intermediate spaces is less than the heat loss unheated window.

The further advantage of the invention is that the formation of Dauwasserschädsn can be avoided by the Zgangsbelüttung the surface elements and equally the fogging of the window panes can be avoided or eliminated in a regulated manner.

The figures explain, for example and schematically, the nature of the Invention.
