Ecoair odorless toilet system - Removal of harmful odors and pathogens like Covid at the source. Reducing the overall power required by traditional exhaust fan systems and making our bathroom green and healthy. 09-16-2022 BSU Health Study / power reduction Re Dr Uwe EcoAir Ventilation System Assessment Background Average bathroom size in the US: 80 sq.ft. Average bathroom volume: 80 sq.ft. x 8 ft. height = 640 cu.ft. Standard commercial bathroom exhaust ventilator o Air flow: 80 cfm o Power usage: 36 W EcoAir Ventilator o Air Flow: 6 cfm o Power usage: 7 W Energy use Computations Bathroom odor-dilution calculations: o 640 cu. ft. bathroom volume / 80 cfm. air flow = 8 minutes o Dilution reduction by 90% = 8 min x 10 = 80 minutes = 1.3 hours o Power requirement: 36 watts x 1.3 hours = 48 watt hours or 0.048 KWH EcoAir Design o Power requirement: 7 watts x 10 min operation = 7 watts x 0.2 hours = 1.4 watt hours or 0.0014 KWH Results: o In comparison to the standard commercial bathroom ventilator, the EcoAir design uses only 3% of the power used by the commercial bathroom ventilator. Explanation of results: o EcoAir captures the odor directly at the “source” while a bathroom ventilator is required to dilute the odor present in the entire air volume of the bathroom, i.e., 640 cu.ft. o Ventilation principles dictate that 10 volumes of fresh air are required to reduce an odor concentration inside a fixed volume by 90%. o Therefore, while traditional ventilators require up to 1.3 hours to dilute the bathroom air, the EcoAir system must operate only 10 minutes thus conserving significant amounts of electrical energy.
