To calculate the electricity consumption in units (kilowatt-hours) for a 1.5-ton inverter split AC used for 8 hours a day, we need to know the power rating of the AC unit and the energy efficiency ratio (EER) or the coefficient of performance (COP) of the unit.
Assuming an EER of 3.5, which is a common value for efficient inverter ACs, we can estimate the electricity consumption:
Calculate the power consumption in kilowatts (kW): Power consumption = Cooling capacity (in tons) * 3.51685 kW/ton Power consumption = 1.5 tons * 3.51685 kW/ton Power consumption = 5.275275 kW
Calculate the electricity consumption per hour: Electricity consumption per hour = Power consumption * Operating hours Electricity consumption per hour = 5.275275 kW * 8 hours Electricity consumption per hour = 42.2022 kWh
Therefore, if you use a 1.5-ton inverter split AC for 8 hours a day, it would consume approximately 42.2022 kilowatt-hours (kWh) of electricity per day.
