DE2803980A1 - Ceiling supported room heating system - has insulating layer above hollow vertical extruded aluminium members housing circulation pipes - Google Patents

Abstract

The room heating system uses ceiling mounted units with hollow members spanning the ceiling from side to side, projecting from the ceiling at right angles, or as a rectangular grid, projecting from it. Each hollow member is made of extruded aluminium, with integral water circulating pipes inside, or enclosing platics pipes. A heat insulating layer is attached to the ceiling, above the tops of the units. The bottoms of the units incorporate condensation collector troughs. These members can also be adapted to act as electrodes for deionisation and dust prevention systems. The system can be used with the structure at the doors and walls.

Description

DESCRIPTION

The additional patent for the ceiling-wall radiation worm system includes three solutions integrated in the ceiling and outside or window wall.

1. Ceiling radiator The ceiling radiator is a further development the so-called "lamella radiator" in the initial registration. This consists of an extruded aluminum profile or a correspondingly shaped vertical heat conducting sheet with integrated heat-carrying water pipe.

The tubes of the room-length profiles become a closed system connected and fixed at certain intervals below the thermally insulated ceiling, so that they subdivide them in the manner of a board or cassette (see Figures 1 to 3) Here, too, the vertical radiator surfaces are predominantly aligned with the vertical ones Wall and cooling surfaces in radiation exchange. By initiating the preroll in the ceiling area adjoining the outer or window wall and corresponding Temperature spread, the heat loss can be optimally compensated.

Since the direct, downward radiation component in the ratio can be kept relatively low for lateral radiation are flow temperatures Possible up to 450C without impairing comfort and therefore economical Solutions given.

When used for room cooling, the dew point can even be undershot and the condensation water is discharged in the channel-like lower cover strip will.

With appropriate electrotechnical insulation, the heat conducting surface also as an electrode for generating a direct current field that is favorable in terms of room hygiene can be used to de-ionize and remove dust from the room air. (only figure 3) The ceiling rcdistor profiles are extruded from aluminum or correspondingly shaped sheets to be produced very economically and easily to assemble without breaking or chiselling work. Therefore, these systems are particularly suitable for renovating old buildings, as the supply lines are also invisible in the frieze of the ceiling can be accommodated.

2. Column or box radiator in the window wall or facade construction integrated column or box radiator is in the vertical window axes and the horizontal transverse tubes arranged so that the thermal radiation is unhindered and can be delivered directly to the cooling surfaces and into the room. The support or box radiators can enclose the profiles of the facade construction at the same time and fire retardant cladding. (see Figure 4) With the appropriate center distance kcnn Even with small radiator sizes, the heat demand of normal room sizes in the low temperature range can be covered up to a maximum heating surface temperature of 450C.

(see Figure 5) 3. Reveal radiator with solid outer walls recessed windows can meet the heat demand through radiator surfaces inserted into the soffit are covered. (See Figures 6 and 7) Here, too, the cold window surface can come through Radiant heat can be fully compensated. The adjacent outer walls, the additional can be thermally insulated inside, receive the required amount of radiation through the radiator surface protruding from the reveal, which is individual for each application can be dimensioned.

This solution is particularly advantageous when renovating old buildings, because here the radiator element without changing the window conduction and without breaking work can be placed on the wall reveal.

(see Figure 8) The following apply to both system solutions Criteria. The disadvantages of conventional radiators lie in the following features: - the conventional radiator gives only the smallest part of its heat radiation into the room in the direction of the already warm interior walls, the main part of the radiation goes to the parapet behind or laterally on the rib surface, i.e. these radiation components must be converted into convection heat in order to be effective to be able to be. The coldest area of the cooling surfaces, the window itself, receives practically no more direct heat radiation and has to be caused by convection alone, i.e. high air temperatures are compensated.

For this reason and as a result of the three to fourfold space requirements is the conventional rib radiator in the W-W. low temperature range with max. 40 - 50 OC flow temperature practically not usable.

On the other hand, there are the advantages of being built into the window wall or

-construction integrated radiator surface: - the heat radiation reaches the coldest window surface unhindered and by the shortest route - the radiation component is greatly increased and the proportion of convection is reduced, even normal window glass is impermeable to long-wave heat radiation, i.e. this is partly absorbed, partly reflected. This gives the window pane a higher surface temperature, so that the outside temperatures can be optimally balanced, - the heat emission in the form of radiation is greatest in the direction of the colder outer surfaces and at the same time least to the warmer inner surfaces. In the full of a heat supply, e.g. from the outside through solar radiation or from the inside through human body radiation (as in schools etc.) the heat emission regulates itself without any control intervention through the effectiveness of the physical law of radiation.

- further advantages are the straight, freely accessible surfaces, which enable clear architectural and design solutions as well as maintenance and reduce cleaning costs considerably.

- as a result of the simple manufacturing and assembly requirements and the energy saving effects, the profitability of the systems is guaranteed.
