Description

  The invention of this application relates to an air purification ventilation facility. More specifically, the invention of this application relates to an air purification ventilation facility having an electrostatic atomizer.

  In recent years, the demand for a healthy and comfortable life due to the improvement of the living environment has increased, and in particular, indoor ventilation and purification of indoor air have been attracting attention as the insulation and sealing performance of residences and the like have improved. As for indoor ventilation, to create a healthy and comfortable air environment, by creating an air flow throughout the house, it suppresses the generation of mold and mites, from moisture that causes condensation, building materials, furniture, etc. Formaldehyde and volatile organic compounds that are generated are discharged.

  In addition, air purification has received particular attention from the relationship with indoor air pollution, the occurrence of mites, and the occurrence of allergies caused by pollen from the outdoors. Various types of air purifiers have been developed and put into practical use as means for removing dust and odors. This air purifier has a so-called filter system as a dust collection function and a deodorization function. The dust collection function is sufficiently practical, but the deodorization function exhibits a sufficiently satisfactory performance. There is no current situation. For this reason, when an odorous substance adheres to clothes, walls, furniture, etc., it has been difficult to remove with the above air cleaner.

  Therefore, as a method for solving this problem, an air cleaner (Patent Document 1) provided with electrostatic atomizing means has been developed. Here, the electrostatic atomization means that water is atomized by applying a liquid such as water to a high voltage. And the odor adhering to the indoor wall surface etc. is removed by the charged fine particle water generated by atomization. Furthermore, according to the air cleaner provided with this electrostatic atomizer, bacteria and viruses can be removed.

And since the charged fine particle water generated from the electrostatic atomizer is charged to the same polarity, it is sprayed over a wide range by repulsive force. For this reason, according to the air cleaner provided with this electrostatic atomizer, an odor, a microbe, and a virus are removed over a wide range.
