Definitions
- Wall element for air conditioning rooms
- the invention relates to a wall element intended for air conditioning by exchanging heat radiation with at least one heat exchange plate and to a method for air conditioning by exchanging heat radiation by means of a heat exchange plate
- Such heat exchange plates are increasingly being used as an alternative to conventional forced ventilation for temperature control, in particular of building spaces, and in particular for cooling them
- a building room is supplied with new or conditioned air via a source air duct that flows into the building room via a source air outlet, which simultaneously influences the temperature of the room due to its temperature and, for example, cools it.
- Conventional source air outlets are usually installed in the foot area
- the conventional forced ventilation systems are disadvantageous in several respects.
- the air conditioning which is exclusively brought about by air renewal, in particular cooling of the room, requires high air exchange rates with often unpleasant consequences for people present in the room.
- the high air exchange easily leads to thermal
- Another disadvantage of conventional air conditioning through forced ventilation is that the air supply via a single source air outlet basically precludes an individual setting of the room climate, i.e. a workplace-specific regulation of the (local) room temperature. Even in the case of multiple source air outlets, the source air supply is only branched according to the prior art , without a control of the air supply through the individual source air ducts being provided.
- undifferentiated ventilation can only be perceived as pleasant by a part of the people present at the same time in working and recreational rooms due to the naturally different sensation of warmth.
- the so-called minimal dissatisfaction rate is a factor conventional ventilation still 5% to 20% even in favorable cases
- the conventional cow fixtures are preferably installed as wall elements in the ceiling area and consist of large cooling plates through which water or air flows, which absorb the heat radiation via a heat exchange surface on the room side. The amount of heat absorbed is dissipated by the cooling water or air flowing in the cooling plate
- the invention has for its object to develop a wall element, which has at least one heat exchange plate for air conditioning the respective room by exchanging heat radiation, in such a way that regulation of both the room temperature and the air renewal is possible without an acoustically or thermally induced nuisance
- the heat exchange plate has a plurality of ventilation openings, and in that the heat exchange plate is flushed with air on one side and part of the air is passed through ventilation openings located in the heat exchange plate The heat that is absorbed by the infrared radiation is dissipated by the air that is spooled past or directed past the heat exchange plate, as in the case of conventional water cooling.
- the heat exchange plate of the wall element according to the invention has a large number of ventilation openings, so that the air used for cooling is not only discharged, but is also partly led into the room
- the wall element according to the invention also has the function of renewing the air.
- the cooling itself takes place in two ways, namely by dissipating the amount of heat absorbed by infrared radiation through the cold air circuit on the rear side of the heat exchange plate (ie inside the wall element and its supply air and exhaust air duct). and additionally through the ventilation of the room by colder air from the openings in the heat exchange plate
- openings are preferably more or less evenly distributed over the entire area of the heat exchange plate and thus provide large-area ventilation of the room.
- the source air supply is very uniform, since high-level turbulence can only 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. If the wall element covers the entire ceiling of the room, any edge turbulence is largely eliminated Due to the large area of the cooling plate provided with ventilation openings, there is a low outlet speed for a given volume flow, which prevents the hitherto unavoidable draft generation because of the increased long-wave radiation exchange
- the heat exchange plate consists largely of metal.
- a perforated or perforated metal plate is used as the heat exchange plate
- the high proportion of metal surface increases the cooling of the room caused by absorption of heat radiation. Due to the good thermal conductivity, the heat absorbed is quickly transported to the side of the heat exchange plate facing away from the room, where it is absorbed and dissipated by the main air stream flowing above the cooling plate
- the ventilation openings located in the heat exchange plate are provided with a filter.
- This type of microfilter not only cleans the air from dust, it also slows down the air outlet speed.This avoids the formation of drafts and also has a This results in even more even air passage over the surface of the heat exchange plate.
- the circular ventilation openings in the simplest case can be enlarged as desired or instead, for example, slits or other relatively large ventilation openings can be provided without the homogeneity of the air throughput being reduced.
- the heat exchange plate can be designed in several parts with corresponding ventilation openings in the spaces.
- the micro filter is preferably applied on the supply air side as a full-surface coating on the heat exchange plate
- a further embodiment provides a device intended for air conditioning with at least two wall elements and with at least two air feeds, each of which is connected to a wall element in order to control its air supply independently of the air supply of the other wall element
- this embodiment in conjunction with an air supply control known per se, enables individual regulation of the room temperature at each individual work station, as a result of which the minimum dissatisfaction rate can be reduced to zero
- the wall element can also be attached to a side wall instead of to the ceiling, 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 are joined together to form a wall element with an intermediate wall that exchanges heat on both sides
- the wall element according to the invention With the wall element according to the invention and its embodiments, it is possible to ensure low-draft, low-noise, fine dust-filtered and individually adjustable air conditioning in rooms with existing forced ventilation. Especially in view of the costs of converting the energy source air to water, the use of the wall elements according to the invention offers a cost-effective way out
- the wall element 1 shown in the figure has, on the side facing the room or the workplace, a preferably metallic heat exchange plate 2 which contains a large number of ventilation openings 3.
- a microfilter 4 for cleaning the air from dust and the like.
- the main flow of cooling air is introduced into the wall element through an air supply 5 and flows largely between the heat exchange plate provided with the microfilter and the rear wall 6 towards the exhaust air line 7, while a smaller part of the air flows through the microfilter and the ventilation openings into the air-conditioning room.
- the wall element on the wall of a building room, for. B. all over the ceiling the main flow of the cooling air can also run between the wall element and the ceiling wall.
- the wall element according to the invention does not require its own rear wall. In the same way, the invention extends to all other obvious modifications of the specific embodiment.
