  • Patent number: 7316261
    Abstract: A heat exchanging system of a ventilating device includes: a heat exchanging housing communicating with an outdoor air passage and an indoor air passage; a rotational shaft rotatably supported at one side of the case of a ventilating device; and a heat exchanging elements mounted at an outer circumferential surface of the rotational shaft at regular intervals, and performing a heat-exchanging operation of outdoor air and indoor air while being rotated by a wind force of outdoor air passing the outdoor air passage and a blow force of indoor air passing the indoor air passage. Thus, any additional driving unit is not necessary to rotate the heat exchanging system, so that a fabrication cost can be reduced, the overall size of the ventilating device can be reduced, and a noise and vibration can be reduced.

  • Patent number: 7267165
    Abstract: A heat exchanger of a ventilating system, including heat exchange plates which are laminated at a predetermined interval and divide an outdoor air path through which outdoor air passes and an indoor air path through which indoor air passes, and a plurality of embossing protrusions which are formed on the outdoor air path divided by the heat exchange plates, for generating turbulence in the outdoor air which flows in the outdoor air path, can improve heat transfer performance by controlling development of a boundary layer by differentiating structure of the air flow of an air path through which indoor air passes and an air path through which outdoor air passes.

  • Patent number: 7237603
    Abstract: A heat exchanger of a ventilating system includes a plurality of heat exchange plates which are laminated at a predetermined interval, a first heat exchange portion which is positioned among the heat exchange plates and through which outdoor air passes and a second heat exchange portion which is positioned among the heat exchange plates in turn with the first heat exchange portion and through which indoor air passes. The first and second heat exchange portions are composed of a plurality of heat exchange members having a predetermined length, and an inner surface of one heat exchange member and an outer surface of the other heat exchange member are aligned to face each other. Accordingly, the heat exchanger can improve heat transfer performance by restraining development of a boundary layer by improving air flowing structure of the heat exchanger.

  • Patent number: 7188666
    Abstract: A heat exchanger of a ventilating system includes: heat exchange plates having first air passage through which indoor air being discharged to outside of a building passes and a second air passage through which outdoor air being introduced to the interior of the building passes which are sequentially formed: first corrugation plates attached to the first air passage; and second corrugation plates attached to the second air passage, wherein the heat exchange plates are made of a paper material with numerous fine holes that are able to generate a capillary phenomenon and loess which radiates far infrared ray. Heat exchange and moisture exchange between the indoor air and the outdoor air are performed simultaneously, and a cleaning function of removing a harmful material contained in outdoor air can be carried out.

  • Patent number: 7168482
    Abstract: A heat exchanger of a ventilating system includes: heat exchange plates laminated with regular intervals so that a first air passage through which indoor air being discharged to outside of a building passes and a second air passage through which outdoor air being introduced into the interior of the building passes are sequentially formed; first corrugation plates attached to the first air passage and obtaining a space to allow outdoor air to pass therethrough; and second corrugation plates attached to the second air passage and obtaining a space to allow outdoor air to passtherethrough, wherein the heat exchange plates are made of a paper material with numerous fine holes that are able to generate a capillary phenomenon. A sensible heat exchange and a latent heat exchange are possible to minimize a change in a temperature and moisture.
