These
tests are not normally run in a special test area or test room
and we refer to them as table top tests.
Temperature
mixing and stratification
Many project specifications will call
for this type of testing. A discharge duct is attached to
the test unit and located in that duct are sensors for reading
temperature. Once inlet airflow, pressures and temperatures
are set, a recording of the discharge sensors is made to
see if specified ratios are met. Primarily dual duct and
fan powered units are subjected to this type testing.
Controls
Many times, special or different digital
control sequences are specified for a building. We have the ability
to setup the test equipment to run under these conditions
to verify the compliance. However we also test electric or
pneumatic, if required.
Terminal
Retrofit Performance
Many older buildings are modified to
meet today's building codes. In many cases the air distribution
equipment is retrofitted, not replaced. This laboratory runs
tests on the old equipment and makes suggestions as to
what changes need to be made to make that equipment work
properly in a modernized building. Most retrofit units are
old dual duct and single duct units.
