Assuming that the duct leaked at class 3 and the test apparatus could generate the static pressure to indicate 24 cfm 250 square feet of duct 24 9 6 100 250 could be tested at one time.
Duct smoke test procedure.
The superior method of generating smoke by chemical reaction eliminates costly equipment and time consuming operations in pinpointing hvac leaks.
Test apparatustest apparatus duct leakage test system consists of duct leakage test system consists of.
This test will be performed annually on each duct smoke detector.
All dampers if installed to.
This smoke test finds out the leaked area in the hvac duct system.
Yes if the duct detector cannot be reset at the facp or annunciator then a separate test reset station will need to be installed for resetting the duct detector per nfpa 72 section 23 8 5 4 6 4.
All boots are temporarily sealed by either the ac contractor or authorized smoke testing personnel.
Ac representative is present during.
3 1 notify the facility work coordinator using the approved electronic work control notification procedure.
The basic idea behind using a duct leakage tester to test for duct leakage is.
The process is simple consist of smoke producing tablet air blower and air passing channe.
Use a calibrated fan to pressurize the duct system.
The sound of the actuator and the time it takes are tantamount to a test.
Portable smoke tester is connected to the supply and return sections of the duct work.
Test proceduretest procedure 1 select duct section for testing 2 measure and calculate duct surface area 3 pg p seal all openings except one.
The duct smoke testing process 1.
A larger meter for example q 26δ p could test 666 s f.
Hvac smoke testing with superior smoke smoke testing effectively and inexpensively reveals leaks and other faults in heat ing and air conditioning duct work.
1 blower with speed control vfd to generate range of pressure flowrange of pressure flow.
Measure the airflow through the fan with the duct system at pressure.
