The Ventilation Rate per Person calculator computes the ventilation rate per person based on the flow rate of fresh air, volume of the space, occupant density and the ceiling height.
INSTRUCTIONS: Choose units and enter the following:
- (q) Fresh Air Flow Rate into the space
- (v) Total Room Volume (e.g. volume of a room)
- (D) Occupant Density (e.g. 64 square feet per person)
- (h) Height of Ceiling
Ventilation Rate (Rp): The calculator returns the ventilation rate in cubic feet per minute. However, that can be automatically converted to compatible units via the pull-down menu.
The Math / Science
The formula for ventilation rate per personis:
`R_p = (q / v) * (D*h)`
where
- Rp = ventilation rate per person
- q = fresh air flow through the room (Cubic Feet per Minute, cfm)
- v = volume of the room (Cubic Feet)
- D = occupancy density
- h = height of the ceiling
HVAC (Heating and Cooling) Calculators
- Air Change Rate: Computes the number of times per hour the air in a space changes based on the flow rate of fresh air and the volume of the space.
- Air Conditioner Size: Computes the number of BTUs needed to air condition a room with a window unit air conditioner based on the size of the room, number of occupants, sun exposure and use (kitchen or not).
- Arithmetic Mean Temperature Difference: Computes the mean temperature difference based on the temperatures of the primary and secondary inlets and outlets of a system.
- BTUs per hour to Heat a Room: Computes the energy (heat) required to heat a space of a certain volume by a specified temperature variance.
