Definitions

  • the object of the invention is a ceiling system for space heating and ventilation with a rotary blow-out element, classified into the systems of space heating with hot air and constant recirculation in and through the system, or a vertical ceiling system for air heating with forced circulation through hot water or steam heat exchangers, according to the principle convection, and is at the same time a ceiling system for air ventilation or room ventilation with forced flow of fresh outside air.
  • the invention is classified in F 24D 5/04 and additionally in F 24H 3/08 and F 24F 7/007.
  • the technical problem solved by this invention is one such construction of the plant, which is uniform Heating larger closed rooms and at the same time Room ventilation with fresh atmospheric and / or cleaned Indoor air enables, with lower heat energy consumption, minimal temperature difference in all extreme points or boundary points of the room, and enables also accelerated heating of the rooms as well Maintaining a constant target air temperature with relatively low operating costs, the construction is simple and compact, their operation program-controlled and remote-controlled.
  • Another known solution from Hoval is a system in two separate versions; after the first run the system is used for heating, after the second for Air cooling in the room.
  • the system consists of the housing, in the upper part with heating or cooling fins Hot water or cold water flow and return are attached. There is an axial fan under the ribs Air turbine attached, the heated air swirl and through it Blow the outflow opening into the room.
  • the lack of this Solution in particular is that they have no ventilation enabled by fresh outside air, and further in that the blow-out air is in the form of a swirling column, as with Tornado, which allows mixing of the air, but not also an even distribution of the heated or cooled air in the whole room.
  • the system housing consists of two in length interconnected and in the top half continuous hollow tubes. Are in the upper part of the housing two adjustable directional flaps executed after the Principle to work openly.
  • One of the hollow tubes is for the Air supply from the room determines the second for the Blow out the heated air into the room, taking one in both Heat exchanger is attached.
  • In the mouth of the Supply pipe is a network with an air filter and above this one Centrifugal fan, with which the air is sucked into the system, executed, which can work in two ways. After The first type is the heated air drawn in through the open ones upper flaps pressed into the room, the neighboring one Pipe is closed with a flap.
  • the air from the intake pipe is pressed into the exhaust pipe where this is through an additional air filter and further over the Heat exchanger moves, then it is replaced by the second Axial fan over the additional air heater after the Principle of the heated air column pressed into the room.
  • the disadvantage or lack of this known solution is mainly in that they are used only for space heating through forced circulation and additional heating of the room air serves, but not also for room ventilation, because it is not Fresh fresh air is supplied to the system.
  • the lack of this system is also that the exhaust air only is directed vertically directly to the ground and that the system is too is weak.
  • the solution of the compact, decentralized Convair roof heating system from the German company Colt is also known, in two basic versions: with vertical exhaust air, by means of an axial fan and with lateral or horizontal exhaust air by means of a radial fan, whereby both versions can be used separately for heating and air cooling.
  • This known solution represents the design of the classic fan heater with hot and cold exhaust air, the disadvantage or deficiency of which is, in particular, that the fan heater does not have a control flap that regulates the direction of the exhaust air and that it does not allow ventilation, since it uses the fresh outside air is not continuously connected, and has no filter for cleaning hard particles from the air.
  • the common feature of all known solutions mentioned is the air circulation through the system and an additional air heating or cooling and only one possible use.
  • the variants relate in particular to the purpose of the design, to the attachment and design of the flaps for air intake and air blowing, and to the type or design of the systems in the blow-out part.
  • the problem that remains unsolved concerns in particular the implementation of room heating and ventilation with one and the same system and thus the supply of fresh outside air into these rooms, further the uneven heating of the entire heated room and thus the temperature fluctuations of the air in the vertical and horizontal of the room, a large consumption of thermal energy, as well as the unguarded regulation of the sucked and blown air.
  • the ceiling system for space heating and ventilation with Rotary blow-out element shown in Fig. 1 is composed of the housing 1 in which the air filter 8 Differential pressure switch 9, electric motor 10 with axial fan 11, Air heater 12 with not designated supply and return of the Heating medium and frost protection thermostat 13 are installed, continue fresher from the feed pipe 4 for feeding Outside air B, from the Rotationsausblaselement 16 for the heated exhaust air C and from electric motor 20 for driving the Rotary blowout element 16.
