Home Ventilation - The quality of your indoor air is important!

---

Why a ventilation system matters?

Ventilation Systems include positive pressure ventilation, heat transfer and energy recovery systems ensure that the air in your home stays fresher, cleaner and drier. A well designed and installed home ventilation system by Modserve NZ offers the convenience of good ventilation by continuously replacing air, independently of weather conditions.

One of our preferred systems is the Lossnay System from Mitsubishi Electric, world leader in ventilation systems.

What are the benefits?

• Ventilation and airtight building design in New Zealand

  Current building regulations now demand homes to be built more airtight as they are subjected to higher insulation standards. But the option of leaving doors or windows open to allow more fresh air to enter is often not the solution from an outdoor noise or security perspective.

• Mould, condensation and moisture control

  The lack of natural ventilation due to air tight spaces can lead to the build-up of moisture-laden stale air within the home. This is the perfect breeding ground for mould that is associated with triggering allergy or respiratory problems. Controlling moisture and humidity levels in the home is seen as the most important step you can take to ensure your home remains mould free.

• Minimising CO2 levels

  High level of CO2 can effect concentration and learning, overall well-being and productivity.

• Fresh outside air instead of attic air

  The absence of significant air movement common in attics means the air is likely to be stale. In addition, build-up of dust, dirt and other contaminants such as mould, insect and rodent droppings makes this air much harder to filter before it is distributed through your home.

How does it work?

The stale air extracted from your home is (RA) Return Air. Return air can contain high levels of CO2, odours and other pollutants. This return air stream also contains energy that Lossnay can recover, which is often not the case with other ventilation systems.

As the stale Return Air is removed, Lossnay’s core ‘recovers’ the useful energy from it. The air is then exhausted (EA) outside along with the unwanted pollutants.

Outdoor Air (OA) is introduced to provide fresh air. It is first filtered, then passed through the Lossnay core. This allows it be pre-heated in winter (or pre-cooled in summer) using the energy recovered from the Return Air.

Supply Air (SA) then enters your house as fresh pre-heated or pre-cooled air.
