Hi,
I have to design engine room ventilation system.The machineries are as follows,
1. 300kW diesel engine
2. 30kw diesel generator
Kindly tel me how to do the calculation for this.
I always calculate for 60 air renewals per hour plus the volume of air consumed by the engines. Only the net volume of the engine room should be taken into account.
I do not know if there is a fixed standard for this so you will find many opinions.
Thank you ,
I have taken that in to my design .Using this,It gives 5500m3/hr flow rate. but engine emit 27kW heat to the engine room ,I use q=mc(t1-t2) eqn to find the flow rate .It gives 8000m3/hr flow rate (with the consumed Air). Kindly give me some advice .
I have never calculated the heat emitted by the engine. It is assumed that, whatever the value, renewing the air 1 time per minute will cause the temperature not to reach exaggerated values. For outdoor air temperatures between 20-32 degrees, that number of renovations should be sufficient.
