The power consumption of an inverter air conditioner is measured in watts (W) or kilowatts (kW). To estimate the power consumption, we need to consider the cooling capacity of the air conditioner and its Energy Efficiency Ratio (EER) or Seasonal Energy Efficiency Ratio (SEER).
Cooling Capacity: The cooling capacity of an air conditioner is usually measured in British Thermal Units per hour (BTU/hr) or tons (1 ton = 12,000 BTU/hr). In this case, you mentioned a 1-ton inverter air conditioner, so its cooling capacity would be 12,000 BTU/hr.
Energy Efficiency Ratio (EER) or Seasonal Energy Efficiency Ratio (SEER): The EER or SEER represents the cooling output (in BTU/hr) divided by the power input (in watts or kW). Inverter air conditioners typically have high EER or SEER values compared to non-inverter models, as they adjust their compressor speed to maintain a consistent temperature, reducing energy consumption.
Let's assume the EER for the 1-ton inverter air conditioner is 15. This means it produces 15 BTU of cooling output per 1 watt of power input.
Now, let's calculate the power consumption:
Power Consumption (kW) = Cooling Capacity (BTU/hr) / EER
First, convert the cooling capacity to BTU/hr: Cooling Capacity = 1 ton × 12,000 BTU/hr = 12,000 BTU/hr
Now, calculate the power consumption in kilowatts: Power Consumption (kW) = 12,000 BTU/hr / 15 (EER) = 800 watts or 0.8 kW
So, a 1-ton inverter air conditioner with an EER of 15 would consume approximately 0.8 kilowatts (800 watts) of power when operating at its maximum cooling capacity. Keep in mind that the actual power consumption may vary depending on the specific model and operating conditions.
