Mitsubishi Electric Vertical LOSSNAY ventilation system

Mitsubishi Electric Australia has launched its newest mechanical ventilation with heat recovery (MVHR) system, which recovers heat from the air inside a home, and transfers it to fresh, dry air introduced from outside, providing energy efficiency in winter and energy recovery in summer.

Suited to residential buildings, including multi-storeys or homes located in inner-city locations concerned with localised air quality, the LOSSNAY technology continuously removes stale interior air from bathrooms, kitchens, toilets and the laundry. Heat is then transferred to the incoming fresh air to warm the home on a cool day. This enables energy efficiency of ventilated air while reducing the demands on air conditioning for heating.

The Vertical LOSSNAY has several new features including a compact slimline design (small enough to fit inside a cupboard), low noise output, and both left and right configurations.

Using onboard temperature sensors, the unit automatically enters bypass mode when it detects the space is hotter than desired and the outside air is cool enough. Bypass mode allows the unit to bring in fresh air from outside without recovering the heat, helping to reduce the need for air-conditioning cooling, such as overnight in summer.

A third filter slot can hold an optional NOx (nitrogen oxides) filter on the supply side of the unit to clean incoming air in polluted environments. The third filter slot can alternatively hold an optional PM2.5 (particulate matter 2.5) filter providing a high standard of fresh air filtration.

The Vertical LOSSNAY can contribute to as much as 40–46% in energy savings on reduced air-conditioning loads depending on conditions. Full energy consumption, CO₂ emissions and electrical expense calculations are available on request.
