Description

Ventilation heat exchanger {HEAT EXCHANGE APPARATUS FOR VENTILATING}

The present invention relates to a heat exchanger for ventilation, and more particularly, to a heat exchanger for ventilation capable of performing heat exchange by bending and stacking an integral sheet and moving indoor air and outdoor air through therebetween.

In general, in order to purify indoor air, contaminated air is inhaled with an anion air purifier with a fan, and fine dust and bacteria up to about 0.01 μm are collected by a filter to deodorize body odor or cigarette odor. (陰) ions are recovered by an ion generator.

In addition, an electric dust collector that collects dust by adding it to a filter inside the air purifier to charge the dust by high-pressure discharge is also used.

In addition to the improvement of indoor air quality due to deodorization or dust collection by the negative ion generator or electric precipitator as described above, various particulate pollutants or environmental hormones in the indoor air come into contact with the body and are inhaled to prevent skin diseases such as atopy and respiratory diseases from time to time. It is desirable to open the windows and sufficiently ventilate to improve the indoor air quality.

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

To this end, recently, a duct-type ceiling type or floor-mounted ventilation system has been developed as an indoor/outdoor ventilation system that takes into account the loss of indoor heat energy. Such ventilation systems require installation of duct facilities through the inner and outer walls of the building. The fan motor power is required a lot due to the generation of static pressure due to construction cost and duct construction according to equipment price, construction cost, and installation space.

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 only 40 to 70%.
