Why Do We Need Fresh Air Ventilation?

Poor indoor air quality can be attributed to many problems inside a building. Excess humidity causes dampness, rot and mould, whilst pollutants are known to be a major cause of damaging health issues such as asthma and eczema. Stale air is also believed to lead to a loss in productivity and low morale. As the demand for improved energy efficiency results in increasingly airtight buildings, natural ventilation proves less effective and drives the need for mechanical ventilation. With increasing legislation, the challenge for designers, installers and occupiers of any building is to find ventilation that’s both effective and energy efficient.

Mitsubishi Electric meets this need with a range of ventilation products covering mechanical ventilation with heat recovery units (MVHR). These systems have been designed to deliver a fresh air supply to a building whilst simultaneously extracting stale air in the most energy efficient manner possible by utilising heat recovery technology.



The Unbeatable Lossnay

Excellent Air Quality and Heat Exchange Efficiency.

Developed and refined over the past 35 years, the Lossnay system has perfected the recovery of energy that would have otherwise been wasted. The units reduce overall energy costs by extracting stale air and then recovering the heating or cooling energy to either warm or cool incoming fresh air.  By utilising this energy, the Lossnay system can save up to 30% on initial capital costs of heating and cooling plant by reducing the load of the occupied space, resulting in the need for a smaller heating and/or cooling system. As Lossnay extracts stale air from a building, heat energy is recovered through the paper core and is transfered into the fresh incoming air.
