The Result of No Bacterial Cross Contamination for the Lossnay
Core and Determining Resistance of the Lossnay Core to Molds
Test report
This document reports the result that there is no bacterial cross contamination for the Lossnay Core.
(1) Object
The object of this test is to verify that there is no bacterial cross contamination from the outlet air to the inlet air of
the Lossnay Core in the heat recovery process.
(2) Client
MITSUBISHI ELECTRIC CO. NAKATSUGAWA WORKS.
(3) Test period
April 26, 1999 - May 28, 1999
(4) Test method
The configuration of the test equipment is shown below. The test bacteria suspension is sprayed in the outlet duct
at a pressure of 1.5 kg/cm
are installed at the each center of the locations of A, B, C, D, in the Lossnay inlet/outlet ducts so that their openings
are directly against the air flow, and then connected to the impinger outside the duct. The impinger is filled with
100 mL physiological salt solution. The airborne bacteria in the duct air are sampled at the rate of 10L air/minute
for three minutes.
