1. What is AC Condenser Sizing?

AC condenser sizing determines the appropriate cooling capacity needed for a space based on area and cooling requirements. Proper sizing ensures efficient operation, energy savings, and optimal comfort.

2. How Does the Calculator Work?

The calculator uses the standard AC sizing formula:

Where:

• \( Area \) — Room area in square feet
• \( Factor \) — Cooling factor ranging from 20-30 BTU/hr/ft²
• \( 12000 \) — Conversion factor (1 ton = 12000 BTU/hr)

Explanation: The formula calculates the required cooling capacity in tons based on room area and selected cooling intensity factor.

3. Importance of Proper AC Sizing

Details: Correct AC sizing prevents energy waste, reduces operating costs, ensures proper dehumidification, and extends equipment lifespan. Oversized units cycle frequently, while undersized units struggle to maintain temperature.

4. Using the Calculator

Tips: Enter room area in square feet and select appropriate cooling factor based on climate, insulation, and room usage. Standard factor (20) for normal conditions, moderate (25) for warmer climates, high (30) for very hot climates or poor insulation.

5. Frequently Asked Questions (FAQ)

Q1: What cooling factor should I choose?
A: Use 20 BTU/hr/ft² for standard conditions, 25 for warmer climates or average insulation, and 30 for very hot climates or poor insulation.

Q2: What is considered a standard room size?
A: Standard bedrooms are 120-200 ft², living rooms 200-400 ft². Measure length × width to calculate exact area.

Q3: Why is proper AC sizing important?
A: Proper sizing ensures efficient cooling, lower energy bills, better humidity control, and longer equipment life.

Q4: What other factors affect AC sizing?
A: Ceiling height, window area, insulation quality, number of occupants, and heat-generating appliances also impact cooling requirements.

Q5: Should I round up the calculated tonnage?
A: Round to nearest standard unit size (1, 1.5, 2, 2.5, 3, 3.5, 4, 5 tons). Avoid oversizing by more than 15%.
