Definitions

  • the invention relates to an air heat / air conditioning unit for private or commercial spaces. Such devices serve the combination of heating or cooling and ventilation.
  • this air heat / air conditioner should have a small footprint and therefore be installed in many places and preferably embedded in a building wall, also its function should be performed reliably with attractive appearance and low noise and high performance with the high standards to meet heating, cooling, ventilation and air conditioning.
  • preheating of fresh air carried by the apparatus should not affect the efficiency of the heat exchanger.
  • an air heat / air conditioner which shallow depth of z. B. only a few centimeters, as of not significantly more than about 6 cm, and in which optionally tempered fresh air supplied via preferably low-noise nozzles in a housing is inserted such that room air is entrained by the fresh air, and that fresh air and / or room air in a predetermined ratio of room air: fresh air, from z. B. 2: 1 passed through the housing under heating or cooling on a heat exchanger element and the air mixture is discharged from the housing in the space to be heated or cooled.
  • the conditions defined in claim 1 with respect to the arrangement and geometry of the nozzles and the heat exchanger element are met according to the invention.
  • the invented air heat / air conditioning unit has only small dimensions in depth and can be mounted even where there is little space.
  • the compact flat design also contributes to the fact that very favorable air flow conditions prevail, which leads to a defined proportionate mixing of fresh air and room air in front of the heat exchanger element.
  • the relationship between room air and fresh air can be written down from device to device.
  • the compact design allows due to the relatively large heat transfer surface of the heat exchanger element also a rapid heating or cooling of the room air conditioning serving air.
