we are having 2 Nos. Rotary Compressor in a single room (Size 10Mtr - Length, 11Mtr - Width & 5Mtr Height) having an Aspatas roof. Now the room is getting fully heated. How i select exhaust fan for this room.
You will need a intake fan with louvers and out flow, the reason is that you all ready taking in air into the compressors. You can create a negative pressure by having an exhaust fan.
I would go with two, one fan for each compressor. The louvers and fans can be temperature controlled so that they will maintain a nice workable temperature.
You did not say what was the prime mover, if it's diesel just reverse the fans, if it's an electric motor run a duct to the fan of the motor. You will still need an outtake of 'make-up' air, louvers again. There are all kinds of ways.
Good luck!!!
