|The humidity in the factory is always detected. During summer months, an air-conditioning machine performs cooling dehumidification, while in winter months, it adjusts humidity by a humidifier built in the air-conditioning machine.
|The air-conditioning machine sends pressurization air, whose temperature and humidity have been adjusted, into the ceiling to pressurize the inside of the ceiling. Differences of air pressure from inside the factory make the air to go out through pore ventilation holes, like mist.
Through this process, the air currents in the factory become constant. Temperature and humidity differences
