Definitions

  • the invention relates to a device for heating and / or cooling of room air with a fan, a heat exchanger and an air outlet.
  • the object of the invention is to improve a device of the type mentioned so that fluidically favorable flow guides in the device, in the outlet and in the room can be achieved and an adaptation of these flow guides to the flow conditions in particular to the air flow and the air temperature can be achieved.
  • At least one air guide is arranged laterally in the air outlet, through which the air is aerodynamically directed to the outlet and through which the outlet cross section according to the temperature and / or the air volume flow is variable in size.
  • the air outlet can be subdivided into two outlet regions by an air guide surface, wherein the air guide surface is rotationally adjustable about an axis which is arranged transversely to the air outlet direction.
  • the air flow is thus guided through a flow-optimized nozzle and / or flap or a flow-optimized channel.
  • a flow-optimized air flow is achieved with air detection and guidance already in the device with integrated outlet, in contrast to outlet constructions, which are subsequently attached to the device.
  • An adaptation of this channel and / or the outlet cross section to the air volume flow, the air temperature and / or the air temperature difference is achieved. This leads to lower pressure losses, lower noise emission and a more stable jet behavior and higher throwing distances. This also leads to a higher level of comfort and lower energy consumption, especially as a flow short circuit is reliably prevented.
  • thermo-mechanical actuator based on the coupling of at least two thermal expansion elements.
  • Fig. 1 shows a first embodiment with a side adjustable
  • Air guide which divides the air outlet into two outlet areas, with different positions of the air guide
  • Fig. 6 thermal expansion elements for adjusting an air guide or the air guide.
  • the device according to the invention forms a fan coil as a decentralized device, in particular for offices, hotels and living spaces, and according to the first exemplary embodiment (FIG. 1) has a housing 1 which forms an air outlet 2 in an outer wall.
  • the air outlet is supplied with the heated or cooled air from a fan 3 via a heat exchanger 4.
  • air guide elements 5, 6 are attached to the air outlet 2 on both sides, which project convexly into the air flow. At least one of these two air guide elements is movably arranged so that in this way the outlet cross section can be changed in size according to the temperature and / or the air volume flow.
  • the air guide element 5 is attached hinged at the end facing away from the air outlet 2 end and motor, hydraulically, pneumatically or thermo-mechanically adjustable by a corresponding, not shown adjustment.
  • thermo-mechanical actuators The position of the air guide element 5 and thus the cross section of the channel in the air outlet are set as a function of air volume flow and / or temperature. This can be realized by electric actuators and connection to the control components or by thermo-mechanical actuators, without a connection to the control components is needed. This solution with thermo-mechanical actuators has as advantages that no electrical Connections and no connection to control technology are necessary. This enables a stand-alone solution.
  • a constructive implementation can also be done by thermal expansion elements.
  • the path specification is effected as a function of a temperature difference.
  • the use of thermal expansion elements and a suitable mechanism also other sizes can be determined, such as the flow or the caloric power.
  • air is sucked in laterally in front of the air outlet into the airflow in the induction principle (FIG. 5).
  • the volume flow is determined by a fluidic arrangement on the measurement of the temperatures of the incoming primary air (air flow), the incoming secondary air (ambient air) and the exiting air flow, if the induction ratio (ratio between primary air and secondary air) is known. If these temperatures are measured with thermal expansion elements, a suitable mechanism results in a travel as a function of the volume flow.
  • a travel is realized by a suitable mechanism that corresponds to the caloric power.
  • an air-guiding surface 7 is fastened or hinged in a rotationally adjustable manner in the rotary region 8, which subdivides the air outlet 2 into two outlet regions 9, 10.
  • the first outlet region 9, which adjoins the adjustable air guide element 5 has a larger air passage cross section than the second outlet region 10.
  • the variant of FIG. 2 to 4 shares the air flow in a primary air flow flowing between the two nozzle elements and a secondary Air flow, which flows past the nozzle on. In the exit then the secondary air flow is entrained by the primary air flow and the air emerges as a single jet of air from the device.
  • FIGS. 3 and 4 in which the two extreme positions of the adjustable nozzle element are shown, essentially the secondary air flow flowing past the nozzle is influenced and thus an indirect adjustment of the nozzle cross-section takes place.
  • the resulting velocity of the total air jet emerging from the unit results from the ratio of the velocities and the volume flows of primary air and secondary air.
  • This version has the further advantage over the previously considered embodiments that the geometries are fixed in the blow-out area and thus an optionally located in the equipment panel grid is ideally tuned to these geometries. Distracting influences due to overlapping, different free cross sections of an adjustable nozzle and a subsequent rigid Beerausblasgitters are reliably avoided.
  • Fig. 6 shows the arrangement of thermal expansion elements 11 at the flow and return for measuring the caloric power.
  • the temperatures at the supply line and the return line of the cooling medium (in the cooling case) or the heating medium (in the heating case) can also be a suitable arrangement of the thermal expansion elements, a corresponding constructive thermal integration and a corresponding mechanism a travel for the air guide. 5 and / or air guiding surface 7 are realized as a function of the calorific power.
