Description

  • The present invention concerns a method for installing a heat exchanging device in a building like e.g. a house, the device comprising a heat exchange module which is arranged for exchanging heat with the open air outside the building. Moreover, the invention refers to a heat exchanging device which is arranged for performing this method.
  • One aspect of the present invention is to provide a heating/cooling device which can easily be combined with another (e.g. already existing) system e.g. in (dwelling) houses etc. without occupying substantial room.
  • Another aspect is to provide a device which can be installed, maintained and repaired without the need for much room and which device can easily be built in and out.
  • Yet another aspect of the invention is to provide a device and system having exterior parts (protuding outside the roof) which comply with the desired and/or prescribed aesthetics of the exterior of the house.
  • Still another aspect is to provide a device which is capable to provide substantial energy savings when the heat exchanging device has the constitution of a so-called "heat pump" which is very efficient in particular in periods in which the difference between the outside and inside temperature is moderate.
  • In order to stimulate the use of such heat pumps (see also http://en.wikipedia.org/wiki/Heat_pump) -meant here are heat pumps which have one heat exchanger exposed to outside air (viz. to extract heat from the outside air and transfer it to the in-house (CH) heating system or vice versa)-a novel configuration has been designed, which is supposed to enable and promote the application of heat pumps as an additional heat source for e.g. domestic use, i.e. in houses and buildings having restricted room to install an additional (heat pump) installation.
  • To that end the method according to the invention comprising the following steps:
    • providing an opening in a roof of the building;
    • providing a housing having one or more air accession openings, the housing extending outside the roof and covering the roof opening;
    • moving the heat exchange device or at least its heat exchange module, from the inside of the building towards the outside through the roof opening, causing that the heat exchange module mainly extends outside the building and is capable to exchange heat with the open air outside the building via the housing's air accession openings;
    • fixing the heat exchange device or at least its heat exchange module to the roof, the roof opening, the housing or any other part of the building.
  • The roof of the relevant house thus is provided with an opening which is covered by a housing which has the functions of:
    • protecting the roof opening against rain, wind etc. (the housing thus needs to be proper connected to the surrounding roofing);
    • housing the heat exchange module;
    • providing aesthetic camouflage of the heat exchange module protruding through the roof (and thus well visible);
    • providing -where needed- protection of the exchange module and/or guiding the outside air to (or from) the exchange module).
  • The housing may be installed from the inside of the house towards the outside or from the outside (i.e. the outer roof side); the installation of the housing is more or less similar to the installation of a roof window or a dormer window.
  • After the housing has been installed and mounted, the heat exchanging device or (when not integrated as one unit) at least the heat exchange module (i.e. the outside air exchange module) can be installed from the inside of the house (e.g. the loft) towards the outside, e.g. by sliding the device or module through the roof opening (covered by the housing) outside and then fixing it to e.g. the roof of roof opening.
  • It is, however, preferred, to use a guiding of sliding frame construction, as outlined here:
    • providing a frame and fixing it to the roof, the roof opening, the housing or any other part of the building;
    • moving the heat exchange device or at least its heat exchange module, from the inside of the building towards the outside through the roof opening, using the frame for guidance;
    • fixing the heat exchange device or at least its heat exchange module, to the frame, the roof, the roof opening, the housing or any other part of the building.
  • According to this preferred option the use of a (auxiliary) frame is proposed which -in short- may be fastened to the roof (opening) and which is used then to guide the heat exchanging device or the heat exchange module in its motion through the roof opening during installation or de-installation (e.g. for repair or maintenance).
  • According to the invention, it is preferred that the heat exchanging device comprises a heat exchange module which is arranged for exchanging heat with the open air outside the building; besides, the preferred device furthermore comprises -or is arranged to cooperate with- a housing, having one or more air accession openings, the housing extending, via an opening in a roof of the building, outside the roof and covering the roof opening; the preferred device, or at least its heat exchange module, furthermore, comprises means for moving it from the inside of the building towards the outside through the roof opening, causing that the heat exchange module mainly extends outside the building and is capable to exchange heat with the open air outside the building via the housing's air accession openings; and the device, moreover, comprises means for detachably fixing the heat exchange device or at least its heat exchange module, to the roof, the roof opening, the housing or any other part of the building.
  • It is preferred that the heat exchanging device either comprises -or is arranged to cooperate with- a frame which is arranged to be fixed to the roof, the roof opening, the housing or any other part of the building, where the device -or at least its heat exchange module- is arranged to be moved from the inside of the building towards the outside through the roof opening, using the frame for guidance and the device, moreover, comprises means for detachably fixing the heat exchange device or at least its heat exchange module, to the frame, the roof, the roof opening, the housing or any other part of the building.
