HVAC Calculations
Calculate cooling loads (BTU), airflow (CFM), and duct sizing equivalents. Optimize heating, ventilation, and air conditioning systems for comfort and energy efficiency.
Room BTU
Estimate the cooling/heating BTU capacity needed for a room based on square footage. A quick rule-of-thumb tool for sizing air conditioners and heaters.
Airflow (CFM)
Calculate Cubic Feet per Minute (CFM) of airflow given velocity and duct area. Essential for balancing HVAC systems and ensuring proper ventilation.
Rect Duct Equiv
Find the circular duct diameter equivalent to a rectangular duct size. Helps HVAC designers convert duct shapes while maintaining friction rates.
Heat Index
Calculate the 'feels like' temperature based on actual air temperature and relative humidity. Critical for assessing safety conditions in hot environments.
Dew Point
Determine the Dew Point temperature where condensation begins to form. Essential for mold prevention and humidity control in buildings.
