The Lossnay ventilator, from Mitsubishi
Running the Lossnay
The Lossnay moves dirty indoor air outside
(exhausting it) and brings clean air from the
outside in (providing air supply).
When it supplies air, it brings outside air close
to room temperature (functioning as a heat
exchanger).
* The Lossnay is not an air-conditioner. It is
a ventilating fan that exchanges heat as it
ventilates.
Since it not only sends indoor air out but also
EULQJVIUHVKDLULQLWZRUNVZHOOLQWLJKWO\VHDOHG
homes.
Since it is a heat exchanger, it provides heating
and cooling at a lower cost than ventilators that
merely exhaust.
%XLOWLQ¿OWHUVUHGXFHWKHDPRXQWRIGXVW
pollen and other particles entering the house in
outside air.
To prevent freezing or damage to the Lossnay
Core, stop the unit if the outside temperature
falls below -10°C and the room's humidity
rises above 40%. (The other conditions about
temperature and humidity are based on Table
1 as a reference.)
