APPENDIX D. PRESCRIPTIVE METHODOLOGY
FOR THE CYCLIC TESTING OF DUCTED SYSTEMS
REQUIRED BY C4.1 AND C4.2 - NORMATIVE
For the purpose of unifonnity in the cyclic test requirements
of Appendix C, the following test apparatus and conditions
shall be met:
D 1 The test apparatus is a physical arrangement of
dampers, damper boxes, mixers, themlopiJe and ducts all
properly seaJed and insulated. See Figures D 1 tluough D4
for typical test apparatus. The arrangement and size(s) of
the components may be altered to meet the physical
requirements of the unit to be tested.
D2
Dampers and their boxes shall be located outside of
the ANSI/ASHRAE Standard 37 pressure measurement
locations in the inlet air and. outlet air ducts.
D3
The entire test apparatus shall not have a leakage rate
which exceeds 20 cfm [0.01 m'ls] when a negative pressure
of 1.0 in H20 [0.25 k1'a] is maintained at the 'apparatus exit
air location.
D4
The apparatus shall be insulated to have "U" value
not to exceed 0.04 Btu/(h·ft2 °F) total.
D5
The air mixer and a 40% maximum open area
perforated screen shall be located in the outlet air portion of
the apparatus upstream of the outlet damper. Themixer(s)
shall be as described in Al'iSI/ASHRAE Standard 41.1. The
mixing device shall achieve a maximum temperature spread
of 1.5°F [0.8 0c] across the device. An inlet air mixer is not
required.
(
D7
The dampers shall be capable of being completely
opened or completely closed within a time period not to
exceed 10 seconds for each action. Airflow tluough the
equipment being tested should stop within 3 seconds after
the airflow measuring device is de-energized. The air
pressure difference (6P) at the nozzle shall be witmn 2% of
steady state 61' within 15 seconds from the time the air
measuring device is re~energized.
D8
Test set up, temperature and electrical measureme~t~
must be identical for nc" and "UI! tests in order to obtain
minimum eITor in CD_ Electrical measurements shall be
taken with an integrating type meter per ANSIIASHR..A.E
Standard 37 having an accuracy for all ranges experienced
during the cyclic test.
D9
Prior to taking test data, the unit shall be operated at
least one hour after achieving dry coil conditions. The drain
pan shall be drained and the drain opening plugged. The
drain pan shall be completely dry in order to maximize
repeatability and reproducibility of test results.
(
DJO For coil only units not employing an enclosure, the
coil shall be tested with an enclosure constructed of 1.0 in
[25 rum 1fiberglass ductboard with a density of61b/ftJ [100
kg/m3] or an equivalent llR" value. For units with enclosur~s
or cabinets, no extra insulating or sealing shall be employed.
D6
The temperature difference between inlet air and
outlet air shall be measured by a thennopile. The
thennopile shall be constructed of 24 gauge thermocouple
wire with 16 junctions at each end. At each junction point
the wire insulation shall be stripped for a length of 1.0 in
[25 rum]. The junction of the wires shall have no more than
two bonded turns.
