METHOD OF IMPROVING INDOOR AIR ENVIRONMENT

摘要

PPROBLEM TO BE SOLVED: To adjust ion balance in air in a room. PSOLUTION: A wall surface in the room is coated with paint containing charcoal powder or a molded body having surfaces coated with paint containing charcoal powder is disposed in the room, and the wall surface or the molded body is connected to a ground electrode buried in the ground to generate ground potential. Since ion balance in air in the room is improved, an environment of the indoor air can be improved. The wall surface or the molded body is connected to the ground electrode through a negative potential generator. PCOPYRIGHT: (C)2009,JPO&INPIT
