1. What is Aircon Wattage Calculation?

The air conditioning wattage calculation determines the electrical power consumption of an air conditioning unit based on its cooling capacity (BTU) and energy efficiency ratio (SEER). This helps estimate operating costs and electrical requirements.

2. How Does the Calculator Work?

The calculator uses the wattage formula:

Where:

• \( Watts \) — Power consumption in watts
• \( BTU \) — Cooling capacity in British Thermal Units per hour
• \( SEER \) — Seasonal Energy Efficiency Ratio in BTU per watt-hour

Explanation: The formula converts cooling capacity to electrical power consumption by dividing by the efficiency rating.

3. Importance of Wattage Calculation

Details: Calculating aircon wattage is essential for determining electrical load requirements, estimating energy costs, selecting appropriate circuit breakers, and comparing energy efficiency between different models.

4. Using the Calculator

Tips: Enter BTU rating (found on the unit's specification plate) and SEER rating (typically between 13-25 for modern units). Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical SEER rating?
A: Modern air conditioners typically have SEER ratings between 14-25, with higher numbers indicating better energy efficiency.

Q2: How does wattage relate to electricity cost?
A: Wattage directly affects electricity consumption. Higher wattage means higher energy costs when the unit is running.

Q3: What's the difference between BTU and tons?
A: 1 ton of cooling equals 12,000 BTU per hour. Residential units are often rated in tons (1.5, 2, 2.5, 3, 4, 5 tons).

Q4: Why is my actual consumption different?
A: Actual consumption varies based on temperature settings, outdoor conditions, unit maintenance, and runtime duration.

Q5: Can I use this for heat pumps?
A: Yes, the same calculation applies to heat pumps in cooling mode, using the cooling BTU and SEER ratings.
