Local ventilation system
Andra Blumberga, Ritvars Freimanis

The invention relates to the energy sector, particularly to systems that ensure the energy efficiency of buildings and indoor air quality.
The invention aims to improve indoor air quality and CO2 removal with reduced energy consumption by reducing the impact of greenhouse gases from energy production on climate change. The ventilation system lowers the CO2 level of the indoor air by using an ion exchange material that works based on changes in humidity with low energy consumption.
The ventilation system comprises an air inlet from the room (2), an air inlet valve (4), a fan (6), a chamber (1) containing an air humidifier (9), an ion exchange material (8), a measuring chamber (7) which includes CO2 sensor (16), temperature sensor (17) and relative humidity sensor (18), room air outlet (3), air outlet valve (5), three-way valve (10), water supply (11), drain pipe (12), water collection funnel (13), water pump (14) and air valve to the environment (15).
The invention can be used in public spaces with a high density of people, where it is difficult to ensure the required air quality.
