I want to calculate how much effect in Watts a ventilation system brings into a room. Will it be correct to use the following equation for this:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]

\dot Q = \dot V \cdot 0,335 \cdot \left( {T_A - T_O } \right)

[/tex]

where 0,335 is actually the Cp of air derived from [itex]{{1005} \over {3600}} \cdot 1,2[/itex]

T_{A}is the temperature the air enters the room with, and T_{O}is the outside temp.

If the air enters the room with a lower temp than the room, how can the energy needed to heat up this air to room temp be taken into account?
