Fresh Air Energy Recovery
Lossnay, by Mitsubishi Electric, is set to revolutionise standards in home ventilation. And it's
designed in Japan for New Zealand conditions.
Here's how it works... stale air is extracted from inside your house to remove damp, odours,
dust, bacteria and gasses. This air is then replaced with allergen reduced fresh air
from outside - unlike some systems that recycle it from the dust-filled attic. But where
Lossnay gets really clever is with its environmentally friendly 'Energy Recovery' system
(sometimes refered to as 'Energy Exchange'). Put simply, energy within the stale air can
be recovered and used to pre-heat or pre-cool the fresh air being vented in. So it warms
the fresh air in winter, and cools it in summer.
This diagram below shows how this cycle works.

The Lossnay Ventilator is the heart
of Fresh Air Energy Recovery.
1. The stale air found within your home is also known as Return Air (RA). This
air can carry unhealthy levels of CO2, and is a
common problem in airtight buildings. However, Return Air also contains energy
that can be put to good use and shouldn't be wasted - which is often the case
with common ventilation systems.
2. As the stale Return Air is removed, Lossnay's heat exchanger 'recovers'
the useful energy within it. The remaining air is then exhausted (EA)
outside along with other unwanted pollutants.
3. Next, Outdoor Air (OA) is introduced from outside to provide the freshest, cleanest air available. It is filtered, then passed through the Lossnay core - this allows it be pre-heated in winter (or precooled in summer) using the energy recovered from the Return Air.
4. Supply Air (SA) then enters your house as fresh, dry and mostly warm (or mostly cool) air.
