ventilation 2

[sethuME]

hi everybody
im working out in ventilation for a turbine room,whose temperature is 5*c greater than the ambient(32*c).is it ok to fix the turbine ventilators @15 AC

Rather than fixing an airchange,I would suggest you to calculate the airflow requirement based on the heat emission from the turbine.

Heat emission in Kw= air flow(m3/s)x1.2(specific heat) X1.02(density)x5 (Temperature rise)

If you do not have turbine heat emission data,you may assume an efficiency of around 30%
and claculate the heat output based on the turbine out put.

The turbine generator heat emmission with the turbine in the space and the generator generated power out of the space would be:

Heat emmission = (1/Eff-1)x Kw output = (1/.3-1)x kw output

But you should add all other heat gains into the space such as:
. lights
. all other heat gain from other equipment in the space
. fan heat = kw/eff since fan & supply air would go to the space
. solar & transmission heat gain to the space
. people heat
You may want to add more cooling to improve the efficiency of the turbine.
