The consumption sheet on the manufacturer's website announces 0.9 kWh/60min of operation - we agree that this corresponds to an hourly consumption of roughly 1kWh, is this correct? So after 8 hours of use, it would be around 7-8 kWh to cool a room? As a comparison, do we have the average consumption per hour per room in Switzerland? Starting from the average annual consumption for a one-person household (~1 room) of 1750 kWh, in daily form, I arrive at 4.8kWh - is it correct to say that this amounts to almost "tripling" one's electricity consumption - or have I missed something in my tablecloth corner calculations?
