Definitions

  • the invention relates to a for air conditioning by exchanging heat radiation certain wall element with at least one heat exchange plate.
  • Such heat exchange plates are used in particular for temperature control Building rooms and especially for their cooling increasingly as an alternative to conventional forced ventilation used (EP 740 114 A2).
  • JP-A-08303822 is a wall element with a heat exchange plate known, which is provided with a plurality of tiny ventilation openings, so that the Wall element has a filter function.
  • a building room is divided over one Source air line that opens into the building through a source air outlet new or conditioned air supplied, which at the same time the Influences the temperature of the room and cools it, for example.
  • conventional Spring air outlets are usually installed in the foot area.
  • the common forced ventilation devices are in several ways disadvantageous - the air conditioning caused exclusively by air renewal, especially cooling the room often requires high air exchange rates unpleasant consequences for people present in the room. So the high Air exchange easily leads to thermal discomfort of people due to drafts, due to a high exit speed of compact source air and a high degree of turbulence in the source air flow.
  • Convection noises are usually very annoying acoustically.
  • This background noise can only partially due to the limited cross-sectional area of the air outlets be reduced.
  • the source air outlets are generally allowed to have a height of around Do not exceed 80 cm to avoid drafts caused by excessive horizontal currents in the Avoid head area. As a result, adequate air supply is only achievable by a correspondingly high flow rate.
  • the invention has for its object a wall element for air conditioning of the respective room by exchanging heat radiation at least one Has heat exchange plate to develop such that the quality, i.e. the purity the air is improved and its temperature in the area of each workplace individually can be adjusted.
  • the air is flushed past or directed past the heat exchange plate heat absorbed by infrared radiation as in the case of conventional Water cooling derived.
  • the heat exchange plate of the er-inventive wall element a variety of ventilation openings, so that the air used for cooling is not only discharged, but also partly in the room is led into.
  • the wall element according to the invention also has the function of Air firing too.
  • the cooling itself is done in two ways, namely by deriving the amount of heat absorbed by infrared radiation the cold air circuit on the back of the heat exchange plate (i.e. inside the Wall element and its supply and exhaust air duct) and additionally through the ventilation of the room due to colder air from those in the heat exchange plate Openings.
  • openings are preferably more over the entire area of the heat exchange plate or less evenly distributed and thus cause a large ventilation of the Space.
  • the source air supply is very even because there is turbulence due to altitude can occur at the edge of the cooling surface.
  • Their size can typically vary between the size of a desk area up to the size of the entire ceiling area vary. If the wall element covers the entire ceiling of the room, any marginal turbulence is largely eliminated.
  • the heat exchange plate is largely made of metal consists.
  • a perforated or perforated metal plate is used as Heat exchange plate used.
  • the high proportion of metal surface increases the heat radiation caused by absorption Cooling the room. Due to the good thermal conductivity, the absorbed Heat quickly to the supply air side, the side facing away from the room Heat exchange plate transported and there through the above the cooling plate main air stream flowing past is recorded and derived.
  • the second feature of the invention provides that in the heat exchange plate ventilation openings are provided with a microfilter.
  • a microfilter not only cleans the air of dust; in addition, the Air self-decelerated. This avoids the creation of Drafts and also has one over the surface of the heat exchange plate more even air passage. This can be done in the simplest case circular ventilation openings arbitrarily enlarged or instead, for example Slots or other relatively large ventilation openings can be provided without that the homogeneity of the air passage suffers.
  • the Heat exchange plate be designed in several parts with appropriate ventilation openings in the gaps.
  • the microfilter is preferably on the supply air side as a full surface Coating applied to the heat exchange plate.
  • Another embodiment provides a device intended for air conditioning with at least two wall elements and with at least two air inlets, from each of which is connected to a wall element for the air supply independent of the air supply to the other wall element.
  • this embodiment enables in conjunction with a known air supply control at each individual workstation individual regulation of the room temperature, reducing the minimum Dissatisfaction rate can be reached to zero.
  • the wall element can also be on a side wall instead of on the ceiling attached, or it can be set up as a free-standing wall surface in the room and air-conditioning a workplace, for example, near the head.
  • a further embodiment provides that both wall elements to form a wall element that exchanges heat on both sides Partition are assembled.
  • the wall element according to the invention With the wall element according to the invention and its embodiments, it will possible in rooms with existing forced ventilation, a draft-free, low-noise, fine dust-filtered and individually adjustable air conditioning guarantee. Especially in view of the cost of changing the air source on water, the use of the wall elements according to the invention offers one inexpensive way out.
  • the cooling surfaces through which air flows according to the invention can also be used Air conditioning systems to be renovated are connected.
  • Air conditioning systems to be renovated are connected.
  • only one is left Part of the existing forced ventilation used for air renewal, which is a reduction of thermally and acoustically disturbing high air speeds has the consequence.
  • the wall element 1 shown in the figure points to the room or the A preferably metallic heat exchange plate 2 facing the workplace on, which contains a plurality of ventilation openings 3.
  • the main stream of Cooling air is introduced into the wall element through an air supply 5 and flows mostly between the heat exchange plate provided with d ( ⁇ m microfilter and the Back wall 6 through to the exhaust air line 7, while a smaller part of the air through the microfilter and the ventilation openings into the air conditioning system Space enters.
  • the wall element on the wall of a building room, for. B. the main flow of the cooling air can also be attached to the entire surface of the ceiling run between the wall element and the ceiling wall.
  • the wall element does not require its own rear wall. In the same way The invention extends to all other obvious modifications of the concrete embodiment.
