3.0 DISCUSSION OF TEST
Unless otherwise noted all tests were performed with the
Microcon’s flow setting selector in the medium position.
The tests began after a four (4) to five (5)
minute settling period, to allow dust concentration to stabilize. After this
settling
period the Microcon™ unit was activated. During this stablilization period
no additional
mixing was provided other than that produced by the room’s dynamics.
Chart
1 - Background Dust Levels - Rm. 336
This test represents the background or
residual airborne dust present in the test room prior
to the introduction of the test dust. This dust is undoubtedly
the result of lack of use because this section of the hospital was not being
used.
Chart 2- Settling Profile - Rm. 336
This test represents
normal settling characteristics of the dust used in the
test, as well as, any inherent flow of the test room.
An airborne dust concentration was generated, mixed and
then allowed to
settle naturally.
Chart 3- Test Number 1- Rm. 336
This test shows the performance
of the Microcon™ (air machine) in the test room
with an elevated level of
dust present. After the initial dust
application
it
was noted that additional openings through which air could flow into
the room needed to be sealed if a true test of the Microcon™ was
to be obtained. After these
openings
were
sealed a second dust application was performed (see Chart 3).
Chart
4 - Test Number 2 - Rm. 336
In this test, all room HVAC
vents and openings were opened (this condition is more
typical of normal usage conditions).
Chart 5 - Test Number
3 - Rm. 336
The test conditions were the same as those
indicated for Test Number 2, but the
Microcon™ was operated with the flow setting on low.
Chart 6 - Test Number 4 - Rm. 335
The test condition were
the same as those indicated for Test Number 2.
Chart 7
- Test Number 5 - Rm. 335
The test conditions were the
same as those indicated for Test Number 2, but the
Microcon™ was operated with the flow setting on low. |
