The power consumption of an air conditioner is typically measured in kilowatts (kW) rather than tons. However, I can help you calculate the electricity consumption in units based on the assumption that you are referring to the cooling capacity of the air conditioner.
To calculate the electricity consumption, you need to know the power rating of the air conditioner in kilowatts (kW) or the current it draws in amperes (A) along with the supply voltage. Typically, the power rating of an air conditioner is mentioned on the unit itself or in the user manual.
Assuming the power rating of your 1.5-ton split air conditioner is approximately 1.5 kW (1500 watts), we can proceed with the calculation.
Electricity consumption (in kilowatt-hours, kWh) = Power rating (in kilowatts, kW) × Time (in hours)
Electricity consumption = 1.5 kW × 8 hours
Electricity consumption = 12 kWh
Therefore, the 1.5-ton split air conditioner would consume approximately 12 units of electricity when running for 8 hours. Please note that this calculation is an estimate, and the actual power consumption may vary depending on the specific model and its efficiency.
