1. What is AC Power Consumption?

AC power consumption refers to the amount of electrical energy used by an air conditioner over a specific period, measured in kilowatt-hours (kWh). Understanding consumption helps estimate electricity bills and environmental impact.

2. How Does the Calculator Work?

The calculator uses the AC power consumption formula:

\[ \text{Consumption (kWh)} = \frac{\text{Watts} \times \text{Hours} \times \text{BEE Star Rating Factor}}{1000} \]

Where:

\( \text{Watts} \) — Power rating of the AC unit in watts
\( \text{Hours} \) — Duration of usage in hours
\( \text{BEE Star Rating Factor} \) — Efficiency factor based on BEE star rating
\( 1000 \) — Conversion factor from watts to kilowatts

Explanation: The formula calculates energy consumption by multiplying power, time, and efficiency factor, then converting to kilowatt-hours.

3. Importance of BEE Star Rating

Details: BEE (Bureau of Energy Efficiency) star rating indicates the energy efficiency of appliances. Higher star ratings (5-star) consume less electricity for the same cooling output, resulting in lower electricity bills.

4. Using the Calculator

Tips: Enter AC wattage (found on product specifications), hours of usage, and select the appropriate BEE star rating factor. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is BEE star rating?
A: BEE star rating is an energy efficiency rating system in India where higher stars (1-5) indicate better energy efficiency and lower power consumption.

Q2: How do I find my AC's wattage?
A: Check the product specifications label on your AC unit, user manual, or manufacturer's website for the power rating in watts.

Q3: Why include BEE star rating factor?
A: The factor accounts for efficiency differences - more efficient ACs (higher stars) use less power for the same cooling output.

Q4: How accurate is this calculation?
A: This provides an estimate. Actual consumption may vary based on room size, temperature settings, outdoor temperature, and AC maintenance.

Q5: Can I calculate monthly electricity cost?
A: Yes, multiply the calculated kWh by your electricity rate (per kWh) and by the number of days used to estimate monthly cost.
