Ventilation or Air conditioning in Mechanical room?

[orator]

A swimming pool building has got an underground mechanical room. The room contains all mechanical equipments (Water heaters, tanks, chemical dosing tanks etc related to swimming pool). Local code says "Ventilation for mechanical equipment rooms shall provide 10 air changes per hour. Fans shall be controlled by a thermostat set at 40°C". What I understand is if the temperature reaches 40C, only then fans will operate. In this case there will be no ventilation (air movement) if temperature is below 40C.Please provide any ASHRAE reference which speaks about temperature control and ventilation rate. Can we provide ventilation with air conditioning in mechanical rooms.

ASHRAE and such standards will not help you against a local code, you should contact building department in your area to get an explanation of this issue

Generally "Code" is the minimum requirement.

Since you have big tanks of chemicals you will certainly need to do better than the minimum.

You'll need to calculate the ventilation necessary to keep chemical concentration below acceptable concentrations.

Maybe the code you mention is not precise as it is written.

Conditioning and ventilation are two different things.

If it prescribes 10 air changes per hour, which it appears to be high, the intention should be to be ventilated all the time, not only when it is over 40ºC.

Is this pool located in a region where ambient air temps reach over 40c ? If chlorine is stored is stored in this room, you may also need not only ventilation , but a wind sock and alarm system as well.

You are judged not by what you know, but by what you can do.
