  • the liquid and air can be stored in a medium container. This air is different from the room air to be heated and can, for. B. can also be referred to as working air or displacement air.
  • the liquid and the air are in an air cushion in the medium container.
  • both the liquid and the air can be routed through a medium line.
  • a conveyor device is available for the transfer of liquid and air between the medium tank and medium line. This air is guided in the device and is used for its operation.
  • a heat exchanger transfers thermal energy to the room air and/or the liquid. The liquid that is fed through the medium line is heated.
  • the heat exchanger and the medium line are arranged relative to one another.
  • the device makes it possible, for example, to switch between the media to be heated, i.e. liquid and room air, in a targeted manner.
  • the medium line is drained with respect to the liquid. This is done by the control unit controlling the conveying device in a preparatory step, i.e. before the actual air mode, so that the conveying device moves air - i.e. the working air - from the air cushion of the medium container through the medium line. This serves to empty the medium line. Due to the movement of the air, the liquid is pushed out or displaced.
  • One embodiment is characterized in that the medium container, the conveying device and the medium line are designed and coordinated with one another such that the amount of air in the medium container, the conveying device and the medium line remains essentially constant.
  • the arrangement of medium container, conveyor device and medium line is therefore so tight that no air escapes and this air circulates in this arrangement.
  • the way in which liquid is removed from the medium container in the direction of the liquid outlet is also designed in such a way that the amount of air remains constant.
  • the conveying device removes air from the air cushion and, after passing through the medium line, feeds it back to the medium container.
  • the air in the air cushion serves to discharge liquid from the medium line. The air is then reintroduced into the medium container so that the amount of air in the air cushion remains essentially constant.

  • the room air is guided from the air inlet 1 by a blower 12 along or past the heat exchanger 6 to the air outlet 2 .
  • a medium container 7 is provided for the liquid, which is connected to the liquid inlet 3 and the liquid outlet 4 and a medium line 8 .
  • the liquid that passes through the medium line 8 can absorb thermal energy from the heat exchanger 6 .
  • the flow of the liquid is effected by the conveying device 9, which comprises at least one pump, for example.
  • the conveyor device 9 is controlled by the control unit 10, which in this embodiment also switches between the different operating modes based on a user setting.
  • An air cushion 11 is present in the medium container 7 for changing between the modes.
  • the medium container 7 is thus not completely filled with the liquid, but an area remains for the air.
  • the medium line 8 is first largely emptied of the liquid.
  • air from the air cushion 11 is guided through the medium line 8 by the conveying device 9 .
  • the delivery device 9 can deliver not only liquid but also air. After the preparation step, in the air mode, the air is heated.

Abstract

L'invention se rapporte à un dispositif pour le chauffage de l'air ambiant et d'un liquide. De l'air ambiant entre et sort du dispositif par l'intermédiaire d'une entrée d'air (1) et d'une sortie d'air (2), et le liquide entre et sort du dispositif par l'intermédiaire d'une entrée de liquide (3) et d'une sortie de liquide (4). L'échangeur de chaleur (6) transfère de l'énergie thermique générée par une unité d'énergie (5) au liquide dans une région d'interaction d'une conduite de milieu (8). Un dispositif de transporteur (9) déplace un liquide et/ou de l'air entre un contenant de milieu (7) et la conduite de milieu (8), et une unité de commande (10) commande le dispositif de transporteur (9). Dans le cas où le dispositif ne doit chauffer que de l'air ambiant dans un mode d'air, l'unité de commande (10) commande le dispositif de transporteur (9) dans une étape de préparation de sorte que le dispositif de transporteur (9) déplace de l'air hors d'un coussin d'air (11) dans le contenant de milieu (7) à travers la conduite de milieu (8).
