In this video, we will discuss and learn about fresh air calculation formula in HVAC.
Fresh air calculation formula in HVAC is a simple mathematical equation that calculates the amount of air required for a room. It plays a significant role in the process of designing and building. It helps to determine how much fresh air needs to be supplied in a room and how much ventilation should be provided for it.
The formula is as follows:
F = A x B x C x D
F - The number of breaths taken (in seconds)
A - The player's current air percentage
B - The player's maximum air percentage
C - The time it would take for one breath at the player's maximum air percentage
D - A multiplier that determines how quickly the player will deplete their oxygen supply.
The formula for calculating the required ventilation rate in a given space is:
Required Ventilation Rate = Fresh Air Volume / Room Area
The fresh air calculation formula was developed by an engineer and is based on the assumption that people breathe at a rate of 8 litres per minute. The formula is derived from this assumption and uses it to calculate the volume of fresh air needed.
The advantages of using this method are that it can be done quickly, it can be done with the use of simple math, and it is easy to understand.
