Description

Ventilation heat exchanger {HEAT EXCHANGE APPARATUS FOR VENTILATING}

The present invention relates to a heat exchange device for ventilation, and more particularly, to a ventilation heat exchange device capable of heat exchange by stacking a plurality of panels when moving indoor air and moving indoor air and outdoor air therebetween.

In general, for the purification of indoor air, the air contaminated with an anion air purifier is sucked into the fan, and fine dust or bacteria of up to 0.01 μm is collected by the filter to deodorize the body odor or cigarette, and the reduced noise due to pollution (Iii) Ion is recovered by an ion generator.

In addition, an electrostatic precipitator that is added to a filter inside an air cleaner to charge dust by high-pressure discharge and collect it is also used.

In addition to improving indoor air quality due to deodorization or dust collection by the anion generator or electrostatic precipitator as described above, various particulate contaminants of indoor air or environmental hormones come into contact with the body and are inhaled to prevent skin diseases such as atopy and respiratory diseases. It is desirable to improve the indoor air quality by opening the windows and ventilating sufficiently.

In order to improve the air quality of a residential area or office space, ventilation by opening and closing of windows is easy, but opening and closing of windows has disadvantages that external noise and dust inflow and heat energy of indoor air are lost.

To this end, in recent years, duct-type ceiling or floor-mounted ventilation systems have been developed as indoor and outdoor ventilation systems that take into account the loss of indoor heat energy, and these ventilation systems must penetrate the inner and outer walls of the building to construct duct facilities. , The fan motor power is required a lot due to the burden of construction cost due to equipment price, construction cost, securing installation space, and static pressure caused by duct construction.

In addition, a plate type heat exchanger is used to reduce energy costs due to the inflow of external air, but due to the structural problem of the plate type heat exchanger, the volume of the exchanger is large, and the heat exchange efficiency is also limited to about 40 to 70%.
