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 referred 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.
Use less, pay less... all year round.

Energy recovered in Winter
If outdoor air is 7°C and the indoor air is at 20°C,
then the energy recovered from the return air would be 14.5°C.
Now the incoming air only needs to be heated by 5.5°C, not 13°C,
thus saving energy and money. With conventional ventilation systems,
this energy would normally be wasted!

Energy recovered in Summer
If the outdoor air is 24°C and the indoor air is 20°C,
then the supply air would be 21.7°C. In summer the house will feel clean and fresh,
even if you leave the house locked up for a long period of time.

The Lossnay difference.
| Old ‘forced’ attic air ventilation |
|
New Lossnay ‘balanced’ ventilation |
 |
Air goes in and gets trapped.
These systems force air into the home from the attic or via an outside grille.
Because the air has been forced in, it leaks out through gaps in the building.
And if that air was heated, you don't just pay to heat lost air but also the continuous
reheating of new incoming air.
What’s more, as newer homes are built to seal in the heat, they no longer have air gaps
to allow effective operation of this type of system.

Air goes in and comes out.
Lossnay’s ‘balanced’ ventilation removes stale air and replaces it with clean,
fresh air at the same rate. But because it recovers heat energy from the stale indoor air,
the need for additional heating is reduced. Which of course, means so is your heating bill!
This perfect balance works for any house type.
