Question
Will tobacco and tar affect
12
the Lossnay Core?
Are there any locations
13
where Lossnay units cannot
be used?
What is the short circulation
14
of the air intake/exhaust air
outlet?
Tobacco smoke tends to adhere to dust, and when it passes through the
Lossnay Core, most of the nicotine and tar will be filtered by the air filter.
However, in very smoky places (ex. smoking lounge, casinos), or when used
for a long period, the tobacco will accumulate and move to the intake side. In
this case, the Core and filter should be replaced.
Lossnay units cannot be used where toxic gases and corrosives such as
acids, alkalis, organic solvents, oil mist or paints exist.
The Lossnay cannot be used in energy recovery in air containing odors.
The Lossnay unit uses the forced simultaneous supply/exhaust method, so
insufficient ventilation found in standard ventilators without air intake is
found.
Caution
(1) The fresh outdoor air supplied to the room should not short circulate and be
drawn back into the return grille - should flow through the entire room.
(2) The relation of the supply and suction air flows must be also considered.
< good example >
Supply grille
Indoor unit of
air conditioner
The air intake/exhaust grille on the outside wall is out in the open, so
there is a natural wind, and short circulation will not occur easily.
However, if the wind blows from the exhaust grille towards the intake
grille, short circulation may occur, so the grilles should be placed as far
apart as possible.
Distance should be three times the duct diameter.
