1. Energy Efficiency Ratio (EER): Look for the EER rating of the AC unit, which indicates its energy efficiency. The higher the EER, the more efficient the AC.
2. Cooling Capacity: A 1.5 ton AC has a cooling capacity of approximately 18,000 British Thermal Units per hour (BTU/h).
3. Power Consumption (Watts): To calculate the approximate power consumption in Watts (W), divide the cooling capacity in BTU/h by the EER. For example, if the EER is 10:
Power Consumption = Cooling Capacity (BTU/h) / EER
= 18,000 BTU/h / 10
= 1,800 Watts
4. Kilowatts (KW): To convert Watts to Kilowatts, divide the power consumption in Watts by 1,000.
Power Consumption (KW) = Power Consumption (Watts) / 1,000
= 1,800 Watts / 1,000
= 1.8 KW
So, a 1.5 ton window AC unit with an EER of 10 may consume approximately 1.8 KW of power. However, it's essential to note that the actual power consumption can vary depending on the specific AC unit and the operating conditions. It's always recommended to refer to the manufacturer's specifications for accurate information on power consumption.
