Improving air quality – room by room

// heating and ventilation

Mitsubishi Electric has led the way on what is known as Mechanical Ventilation with Heat Recovery (MVHR) in the commercial sector with its popular Lossnay system and the manufacturer has now translated all of this technical know-how into an easy-to-fit unit that is an ideal and cost-effective way of introducing MVHR, room by room.

“We’ve worked with housing associations to introduce full Lossnay systems but this can involve major refurbishment work as it requires ducting throughout a property,” explains Janvi Patel, ventilation expert for the Hatfield-based company.
“Our VL-50 Lossnay unit can be fitted to an outside wall and ducted out using one single pipe, it will then capture up to 80% of the heat energy that would otherwise be wasted.”
Lossnay achieves this by using a fine paper core, which allows the heated outgoing air to transfer this heat energy to bring the incoming air closer to the room temperature, thereby keeping the inside fresh without wasting energy.
Pollutants, smells and even outdoor noise are filtered out by the unit, meaning that the inside is both fresh and comfortable, whilst the heat recovery element also means it is highly energy efficient.
Only one single pipe connection to the outside is needed for the unit, making it ideal for retrofitting into existing buildings.  The VL-50 is available as a pull-cord, hard-wired, or wireless remote controlled unit and measures just 52cm by 24.5cm.
The unit can be fitted vertically or horizontally to suit the interior décor and provide installation flexibility and needs no pipework other than the connection through the wall to the outdoors.
“Lossnay recovers both latent heat and sensible heat, meaning the incoming air is comfortable and the home doesn’t suffer from static or dryness,” adds Patel, “it’s all about increasing the comfort for tenants whilst minimising the energy needed to do so.”
The added advantage for social housing providers as well is that adequate effective ventilation is known to help reduce instances of mould and mildew, which are also harmful to health and, if left untreated, damaging to the fabric of the building.
The units price start at £208 which makes them a really cost-effective way of improving indoor air quality for tenants, whilst helping landlords keep maintenance regimes to a minimum.
