About Ventilation Heat Loss Calculator (Formula)
The Ventilation Heat Loss Calculator is a tool used to estimate the heat loss through ventilation in a room or space. It helps determine the amount of heat that is lost due to air exchanges per hour, the volume of the room, and the change in temperature.
The formula used in the calculator to calculate ventilation heat loss is as follows:
Heat Loss (Q) = 0.33 * n * V * ΔT
In this formula:
- “Heat Loss” (Q) represents the amount of heat lost through ventilation. It is typically measured in units such as watts (W) or British thermal units (BTUs).
- “n” refers to the air exchanges per hour, which represents the number of times the air in the room is completely replaced within an hour.
- “V” represents the volume of the room or space being ventilated. It is measured in cubic meters (m³) or cubic feet (ft³).
- “ΔT” represents the change in temperature, which is the difference between the indoor and outdoor temperatures. It is typically measured in degrees Celsius (°C) or degrees Fahrenheit (°F).
By inputting the values of air exchanges per hour, room volume, and change in temperature into the calculator, the tool calculates the estimated heat loss due to ventilation.
The Ventilation Heat Loss Calculator simplifies the process of estimating heat loss by automating the computation based on the provided parameters. It is commonly used in the field of building design, HVAC (heating, ventilation, and air conditioning) systems, and energy efficiency assessments to determine the impact of ventilation on heat loss and optimize energy usage.
