hi,

pls let me know the design of underground car park ventilation systems and how to select the fan also.

You are asking in the wrong Forum, my friend. This forum is for Refrigeration Engineers.

This is not really the place to look for answers. However, to be short:

You need ventilation 1.5 cfm/sq.ft. which is the IMC standard (International Mechanical Code)

You need to start ventilation when CO2 levels reach about 25 ppm. As a rule of thumb, you need a CO2 senser for every 2000 sq.ft. of basement parking garage.

The best would be to consult with your local Fire Authority and the corresponding by-laws in your area.

I wish I could be more helpfull, but I'm committed to my trade, Refrigeration!
