Definitions
- the invention relates to a flat cooling and heating element to form a covering for the ceiling of a Space and for integration into such a cladding according to the preamble of claim 1.
- Such flat cooling and heating element is from DE-U-92 05 391 known.
- cover panels made of ceiling panels put together the sound-absorbing properties to have. These can also be used as cooling and heating elements set up to air-condition a room serve or for both building physics tasks can be selected at the same time.
- the temperature (cooling) of the room under the cladding is carried out using selectively provided Air outlet openings, if necessary via the entire cladding distributed by the heated or Cooled air flows are blown into the room using fans be the direction of each airflow is adjustable so that the air circulation in the room can be influenced.
- the object of the invention is therefore to a cooling and heating element of the type mentioned in such a way that, on the one hand, an even, draft-free temperature control of the room is possible and Others have an individually adjustable temperature control to accomplish.
- Such a cooling and heating element has the advantage that the first supply air flow generated by the fan over a large area and essentially vertically downwards the top layer, split into many partial flows, with because of the flow resistance in the porous cover layer greatly reduced flow velocity can flow out.
- the cooling and heating element can because of the large Outflow surface now with a significantly higher temperature difference on the heat exchanger and thus with one higher efficiency - the system works extremely effectively with both heating as well as with cooling.
- Those exiting the room Partial flows mix because of their low kinetic Energy quickly with the indoor air, so that drafts does not arise, and the diffusion of the partial flows into the Indoor air ensures rapid temperature compensation.
- the forced flow through the porous cover layer allows in interaction with the radiation component that Surface of the top layer with relatively high temperature differences to act, d. H. already in or short the desired temperature compensation takes place under the top layer with the indoor air instead. It is synonymous with cheaper energy transport, the in turn justified the better efficiency.
- the mechanical structure of the cooling and The heating element is relatively arbitrary. It can be as thin-walled sheet metal cassette or sandwich construction be formed from several layers.
- the fan and the heat exchanger can be outside the Ceiling paneling or even provided outside the room his; it is also irrelevant in the context of the invention whether the air flow into the space between the cladding and ceiling of the room or separately is fed into a cooling and heating element.
- a fan and / or a heat exchanger in its air flow provided the interior of the cooling and heating element are, for example, and at least the fan in one separate housing. This way the rest Components of the cladding are kept very simple.
- the - thermally passive - ceiling tiles can trained in sandwich construction and from one Carrier plate and on this on one or both sides with a thin cover film glued to the carrier plate be composed.
- the carrier plate is there preferably made of a foamed material.
- the cover layer of the cooling and heating element according to the invention is best made of a fleece or fabric made of glass, synthetic and / or natural fibers; it is for them first supply air flow permeable.
- that of Side of the room facing away from and facing the ceiling Cooling and heating element with one for this first supply air flow impermeable cover is best made of a fleece or fabric made of glass, synthetic and / or natural fibers; it is for them first supply air flow permeable.
- the convection intensity is improved by at least one air outlet opening breaking through the cover layer for an undisturbed out of the fan and / or the heat exchanger conveyed into the room second supply air flow, which then also, for example across the fluidically separated space above the cladding by a cooling and heating element can be flowed through.
- appropriate supply air channels may be provided so that both supply air flows the same functional element can escape, together or individually; the respective Arrangement can be according to local conditions to be selected. That way it is possible several, overlapping and penetrating To create air circulation in the room.
- the heat exchanger with a Drip pan for condensate is provided; Such an arrangement is particularly effective in cooling mode good services.
- the arrangement can be made in this way be that the condensate by evaporation in the room is dissipated, but it is also possible to use a corresponding one Lead the condensate line out of the room.
- Cooling and heating element is provided that the fan separated from the room with a filter on the intake side is.
- the filter can be attached visibly from the room be so that its pollution level is continuous can be checked without the filter should be expanded.
- cooling and heating element too is still sound absorbing if it is Part of a so-called acoustic ceiling is that then absorbs sound throughout the area; the tempering Function of the cooling and heating element not affected by this.
- the temperature control of the supply air flows can, however set out above, outside the cooling and heating element respectively; but it is convenient if the cooling and heating element a heater and / or cooling for the Supply air flows are provided so that a compact, itself containing all the necessary functional elements Unit is formed as a module for any customizable cladding serves and for example also thanks to its interior decor Can perform tasks.
- the invention is further characterized by a Cladding for the ceiling of a room, at least in a partial area air-conditioning the room according to the invention Contains cooling and heating elements, otherwise but from appropriate, but without fan, heating / cooling and heat exchanger designed, purely clad Ceiling panels are assembled; in the Rule is sufficient because of the invention Cooling and heating elements intensive convective temperature control of space if only a small one Part of the ceiling cladding with such "active" thermal functional elements is equipped. Because of the usually regulated by the window Fresh air supply is beneficial if the air-conditioning Cooling and heating elements at least partially are provided near the windows.
- a particularly intensive air circulation arises on if - in the area of the window and in the suction area of the fan - at least one air outlet is set so that a first partial flow is directed vertically downwards, which after impact is led up again on the floor, and if at least one other air outlet opening like this is set to be oblique, for example at 30 ° to the ceiling, down into the room directed second partial flow that forms in the area the window is also deflected upwards again becomes.
- the partial flow on your Path through the room approximating its room temperature, before going straight to a person in the room meets.
- the invention is based on the drawing an embodiment explained in more detail.
- the only Figure shows an inventive cooling and heating element as part of a covering for a ceiling in the schematic longitudinal section and in its installed state.
- the cooling and heating element Ke is designed as a sheet metal cassette, their after space Ra and a space Zr directed between the ceiling and the cladding Surfaces the inside of the cooling and heating element Ke limit.
- the cooling and heating element Ke contains on it in the Drawing right side of a separate housing Gh, the is open to the inside.
- a cylindrical fan Lü which from the Room Ra underneath the cladding the one there Sucking in air.
- This can be pure indoor air Rl, it is outside air Al or a mixture of both; a passage Df for the outside air Al through a
- the outer wall Aw of the room Ra can be used for this purpose if necessary be adjustable so that the admixture can be controlled by fresh outside air Al.
- the supply air provided by the fan Lü flows through first a heat exchanger Wt, which is used for temperature control serves the supply air, which, if necessary thermostatically controlled, cooled to a preselected setpoint or is heated; the details are customary and not shown in the drawing.
- the heat exchanger Wt and the fan does not have to be in the housing Gh or at all within the cooling and heating element Ke be provided; rather, the temperature control can also done by an externally provided heat exchanger, so that the required functional elements not installed in the cooling and heating element Ke Need to become.
- the heat exchanger Wt is equipped with a drip pan Kw, the condensate generated during cooling picks up; it can be arranged that the relative evaporate small amounts of condensate, alternatively with the support of an additional heater.
- the supply air cannot flow into the space Zr because of this from one adjacent to the space Zr, on the Surface of the cooling and heating element Ke applied Cover ad is prevented.
- the supply air is fed into the supply air flows after it has been tempered Zs1 and Zs2 split.
- the supply air flow Zs1 flat with a relatively high pressure loss from the cover layer Ds of the cooling and heating element Ke in the room Ra
- the supply air flow Zs2 is over an air outlet opening Lö in the room Ra with little Pressure loss directed.
- the supply air flow Zs2 already has before passing through the air outlet opening Lö experience intensive temperature compensation, conditionally through the room air surrounding the entire element Ke.
- the air outlet opening Lö is designed that the supply air flow Zs2 can exit directed. It has proven to be particularly advantageous when a first partial flow Ts1 vertical and a further partial flow Ts2 is directed obliquely downwards, this one below 30 ° to 45 ° variably adjustable to the level of Cladding.
- the arrangement of the cooling and heating elements Ke nearby a window Fe has the advantage that a heat or Cooling load of people in the room Ra can be avoided.
- the outside air Al becomes direct and low-loss sucked in by the fan Lü.
- the air outlet opening in the heating and cooling elements can have another air outlet La for generating a directional flow be provided, which is advantageously below the window is arranged.
- This air outlet La creates a directional flow, through which the room climate can be influenced in the desired sense is.
