Publication number: 20060219381Abstract: The present invention relates to an apparatus for ventilation systems which include an element for the transfer of heat from warm exhaust air (taken from inside a building) to cooler exterior fresh air which is drawn into the building. The present invention in particular provides an apparatus whereby, during a defrost cycle, interior air may circulate through both of the fresh air and exhaust air paths for delivery back into the building, i.e. the warm interior air, used as defrost air, may be able to circulate from the interior of the building into the ventilation apparatus and back to the interior of the building. The apparatus can thus use interior air as defrost air while diminishing or avoiding the creation of a negative air pressure in the building.Type: ApplicationFiled: May 23, 2006Publication date: October 5, 2006Inventors: Frederic Lagace, Jean-Francois Grondin, Pierre Cusson, Michel Julien, Daniel Marcoux

Publication number: 20050006058Abstract: Various systems and apparati as well as devices and structures are provided which may be used or incorporated into air handling systems (e.g. (air) ventilation systems and apparati) for the manipulation or control of air in a enclosure such as a building, a room of a structure such as a residence, and the like. Such air handling systems (e.g. ventilation apparati or systems) may for example include an element for the transfer of heat from warm exhaust air (taken from inside an enclosure e.g. a building) to cooler exterior fresh air (drawn into the enclosure e.g. building). The present invention further relates to air handling systems (e.g. ventilation systems and apparati) which may not only exhaust stale interior air to the outside of an enclosure but as desired or necessary also intermingle a portion of such stale air with fresh air for delivery of the intermingled air back into the enclosure (during cold or warm weather). The present invention in particular relates to air handling systems (e.g.Type: ApplicationFiled: August 2, 2004Publication date: January 13, 2005Inventors: Martin Gagnon, Eric Charlebois, Michel Julien, Daniel Marcoux, Jean-Bernard Piaud
