Definitions

  • the present invention relates to double skin fagade elements of the kind of composite windows or box-type double windows comprising an inner glazing and an outer glazing with an intermediate air space in between.
  • a further variant applied in practice consists in blowing dry air into the fagade element and to put the cavity under overpressure in order to avoid the uncontrolled sucking in via the leakages. This, however, requires considerable elaboration in connection with the central generation of dry air and the distribution via air ducts into the individual fagade elements.
  • air conditioning technology it has already been known to condition air by dehumidifying and cooling down and to heat it up again by a subsequent heating process.
  • Air conditioning plants known in the air condition technology operate with relatively huge air flows with high air velocities and elaborate controls.
  • a device has been known which ensures the keeping dry of the air flowing into a fagade interior space by using a drying agent or another active agent.
  • the principle of this patent application is to organize, via valve controls, the flow paths of the in-breathing and the out-breathing air.
  • the control of the valves is effected via pressure-sensitive sensors in the fagade element.
  • the pressure values required to open the valves are stored by a soft ware.
  • the disadvantage of this device is the high technical elaboration with a view to valves, control and adjustment for the co-ordination of the numerous air paths and the deduction of the condensate, the complex control by a soft ware as well as the necessity to have a drying agent which has to be serviced and, at intervals, has to be renewed as well.
  • the advantage of the present invention consists in the simultaneous use of two physical processes, namely the sucking in of air by contraction when the air space in the fagade element is cooled down, and the dehumidification. This is obtained by cooling either the walls of a flow-in channel or cooling elements integrated in the flow-in channel, which leads to immediate condensate formation and hence drying of the inflowing air.
  • the further advantage consists in that air conditioning is obtained by means of minutest air velocities and very small air amounts.
  • the invention makes intelligent use of the natural processes, such as expansion and contraction of the air, for adjusting the flow direction within the conditioning units so that the device functions automatically and independently.
  • the advantage consists furthermore in that the size of these air conditioning plants is reduced in such a way that they may be accommodated even in a small fagade profile. In this way, the condition is met to accommodate the air conditioning plants, decentralized, in each individual fagade element of a building. Moreover, the plant may be produced so economically that it may be employed hundredfold in one single building, depending on the number of windows.
  • the present invention suggests to preferably use at least the cold side of thermoelectric elements but at the same time make also use of the warm side and to condition the air by cooling, on one hand, or additionally by heating, on the other. These opposing processes occur either simultaneously or in a timely sequence one after the other in favour of air dehumidification in case of cooling and, moreover, to avoid icing over of cold surfaces in case of heating.
  • the invention makes use of the suction effect in case of the contraction of the air by cooling down the intermediate air space in the fagade element, or the reversal of the air flow in case of a pressure build-up by heating the air in the cavity of the fagade elements.
  • this task is solved by making use of the waste heat of the Peltier element.
  • the idea of the invention is that the "in-breathing" air of the fagade element so be organized that air drying without icing up is assured.
  • a inflow tube is preferably formed as cooled condensation tube and is disposed vertically with openings showing downwards so that the condensate developing in the condensation tube may downwardly freely drop out and/or into a collector.
  • a further idea of the invention therefore, consists in simultaneously forming the air conditioning unit as drainage tube for the condensate developed.
  • a rule to be kept may be to cool the inflowing air not only down to its condensation temperature but rather significantly below the dew-point temperature in the fagade element itself. Only when sticking to this rule is the fagade element permanently free from condensate. It is important to dehumidify the inflowing air and to lower the relative air humidity so far that during cold weather periods sufficient reserves have been formed when the dew-point in the cavity of the fagade element is undercut. In critical climates, it might, therefore, be advisable to insert a drying agent cartouche passed by air after the condensation but before the cavity. By the drying agent, residual humidity in the air is withdrawn in order to further reduce the condensation temperature of the air to be breathed in. When the cavity is "breathing out", the humidity stored in the desiccant will advantageously be withdrawn again so that the desiccant is again activated for the following cycle.
  • the spirit of the present invention with reference to the control and the regulation of the air flows in the air conditioning unit is to make use of the contraction, or expansion, of the air in case of temperature changes in the fagade element.
  • An after flow of air dried in the air conditioning unit will always come up if and when the fagade cools down and sucks in.
  • energy irradiation for instance sun irradiation
  • heating up and hence expansion of the heated air occurs which subsequently flows out again through the air conditioning unit into the opposite direction.
  • the intermediate air space cools down again, the air volume collapses, and cooler and respectively dryer air is again sucked in via the air conditioning unit.
  • the directions of the air flows turn round.
  • the Peltier element Via an outer or inner temperature sensor in the intermediate air space of the fagade, the Peltier element is switched on as soon as cooling sets in. If the fagade intermediate space heats up, the Peltier element switches off, the air flow turns round, expanding air flows out through the condensation tubes. If the fagade intermediate space cools down, the Peltier elements switches on. According to the invention, therefore, the cavity in the fagade element itself serves as a controller and, additionally as an "air pump" and defines the direction of the air flows in the air tube.
  • the suction port In colder latitudes it is of advantage to suck in the air from the outside, in tropical climates from actively cooled down interior spaces. It is essential of the invention to correctly dimension the size of the suction port.
  • the suction port should be dimensioned large enough so that no under pressure will occur in the intermediate air space of the fagade to avoid undesired sucking-in of humid interior space air via leaky joints of window and fagade structures.
  • the air supply and exhaust air openings of the air conditioning unit should be made so small that no undesired ventilation occurs.
  • 1 m 2 of air volume enclosed in the fagade element requires an opening cross section of from about 100 mm 2 to about 200 mm 2 .
  • the out-flowing air should either be deducted again via the condensation tube, or further independent outflow openings should be provided with check valves.
  • a check valve may additionally be inserted on the in-flowing air side.
  • Sucking in is effected via an at least one lengthy vertical condensation tube made of copper disposed for instance as draining tube in a fagade post.
  • An advantageous side effect of the innovation is that, within the sucking-in tube, possible dust and dirt particles from the air sucked in will deposit at the walls, or stick to the humid walls, which means that a self-cleaning effect of the air occurs.
  • the condensation tube should, therefore, be provided exchangeable as a maintenance element so that it may be cleaned from the inner dirt particles sticking to the walls.
  • the inflow opening of the tube and, perhaps additionally, the inflow side to the intermediate air space should be provided with filters so that remaining dirt particles may be filtered out.
  • the condensation tube therefore, constitute at the same time as dust catcher and cleaning system for the air flowing into the fagade elements.

  • the Peltier elements are controlled by temperature sensors disposed outside of, or within, the intermediate air space.

  • a further method to control the Peltier element includes an air flow sensor in the condensation tube. As soon as air flows in, the Peltier element switches on. When the fagade elements are heated up, the air expands, the air flow turns round, and the Peltier element switches off.
