BUILDING SYSTEMS ANALYSIS

Evaluate flow distribution in clean

rooms, data centers, hospital

quarantine rooms, atriums and many

other applications

Optimize data center configuration and

identify “Hot” zones.

Identify moisture level & distribution in

indoor swimming pools and water parks

Evaluate smoke & carbon monoxide

levels in emergency exit corridors for

scenarios involving localized fire events

Human (thermal) comfort

Natural ventilation effectiveness

Contaminant control

Exterior wind conditions



DATA CENTER ANALYSIS

Data center air flow can be analysed using

CFD software which reveals detailed

information about the way the air is

distributed throughout the room.

Room optimization can be performed

virtually rather than by trial and error.

TDMG has performed analysis on data

centers with CRAC systems and central

under-floor ventilation systems.

The results of the analysis show the areas

which may not be seeing adequate airflow or

rack sections which may have inlet

temperatures which are too high due to

recirculation or other.

Detailed rack analysis can also be

performed, where necessary, to identify the

performance of the rack equipment.



INDOOR POOLS AND WATERPARKS

Proper ventilation for indoor pools and waters

parks is a must in order to achieve a good

design, thermal comfort for the bathers and

spectators, as well as safety concerns.

TDMG has performed a number of ventilation

analyses to establish humidity levels, human

comfort parameters, mean age of air,

condensation concerns on windows, and

exhaust of pool chemicals.

In many cases, the analyses performed

identified areas of air recirculation, high

velocity jets, and condensation issues that

would have resulted in on-site corrective

action. Identification of these concerns

allowed for redesign of the ventilation system

(example: relocation of supplies and returns)

well before the ventilation system was built.



CLEAN ROOM ANALYSIS

Our ventilation analysis capabilities allow us

to model clean rooms and identify areas of

concern.

Having early visibility of problem areas

means that the issues can be solved early in

the design cycle and in an effective manner

rather than after the fact.

Contamination zones can be eliminated.

Plenum design can be optimized for optimal

flow performance.

Humidity control can be evaluated early in the

design.

All the above can be done prior to investment

of capital.
