Description

Stand type heat exchanger

The present invention relates to a stand-type total heat exchanger, and more particularly, to a stand-type total heat exchanger capable of improving noise reduction efficiency.

In general, the air in the closed space has to be replaced with fresh air from the outside because the content of carbon dioxide is gradually increased by the breathing of living beings and at the same time it is polluted and interferes with the breathing of living things.

In recent years, as heating and cooling are common, indoor spaces are becoming more closed due to problems such as energy saving and noise. Also, in the case of a new house, various harmful substances generated indoors cause skin diseases such as atopy and allergies and respiratory diseases. For this reason, the ventilation problem of indoor air is emerging as an important issue.

For such ventilation, a ventilation device for forcibly discharging indoor air to the outside using only one blower has been used in the prior art.

In the conventional ventilation device as described above, when only indoor air is forcibly exhausted using a single blower, cold air and heat in the room are discharged to the outside without filtration and are lost, and outdoor air is introduced through a door or window gap. As a result, cooling and heating as much as the loss was required, resulting in unnecessary waste of energy.

In addition, foreign substances contained in the outside air were introduced into the room without filtration, so that the function of simply removing odors was performed rather than the effect of pleasant ventilation.

In order to solve the above problems of the prior art, a heat exchange type ventilation device has been developed in recent years that allows the incoming outdoor air to maintain an appropriate temperature by exchanging heat between indoor air and outdoor air.

In such a heat exchange type ventilation device, the inflow of the exhausted air undergoes heat exchange to some extent and flows in. However, if the temperature difference between the outside and the room is large, that is, in midsummer or midwinter, a loss of room temperature occurs, so a separate heater or There is a problem that the air conditioner must be operated.

In addition, since the conventional ventilation device is mainly used in large air conditioning rooms such as buildings or factories, or is fixedly installed by being buried in the ceiling of an office, there are problems such as noise and inconvenience of installation in general homes or small indoor spaces.

In addition, the conventional ventilation device has a narrow flow path, and at a high air volume, a considerable pressure is applied to the flow path to generate vibration and noise, and there is a problem in that the indoor air quality deteriorates because only ventilation is performed regardless of the outdoor air quality.
