The importance of correctly controlled humidity 

A dry environment offers the ideal conditions for the proliferation of bacteria and viruses, and the survival rate of these micro-organisms drops rapidly at relative humidity levels above 50%. Excessively humid environments, on the other hand, encourage the proliferation of mold and mites. 

Precise humidity control is therefore an important factor in maintaining ideal, healthy conditions. 

As shown in the figure, the Lossnay exchanger consists of a structure in special treated paper allowing two different air flows to cross one another and exchange thermal energy. 

Partitions separating the inlet and outlet channels prevent incoming fresh air from ever mixing with outgoing air. 

The Lossnay exchanger performs a highly effective total exchange action for both temperature (sensible heat) and humidity (latent heat) – the system uses moisture permeable partitions in specially treated paper to allow stale air to be vented externally and fresh outdoor air to be fed to the indoor space with absolutely no mixing between the two air flows. 

Comfort and energy savings 

With universally recognized efficiency, Lossnay heat exchanger ventilation units use energy recovery to offer significant energy savings. 

A conventional ventilation system vents treated indoor air into the outdoor environment and replaces this air with outdoor air, causing the room to lose heat in winter and heat up in summer. 

This loss of heated/cooled air means that energy must be expended to restore comfortable temperature conditions in the indoor space. 

The result of this is notably higher air conditioning costs. 

To solve this problem while still ensuring the necessary air exchange, Mitsubishi Electric offers a range of thermal energy recovery ventilation systems, which minimize air conditioning costs. 

All Lossnay units are equipped with class “G3” air filter. 

LGH models may also be equipped with a class “F7” high efficiency filter. 

Low noise 

Precise control over the flow of treated air significantly reduces the sound pressure values of the LOSSNAY unit by up to 18 dB(A). 

All LGH-RVX units ensure ideal acoustic comfort, including for residential applications, libraries, offices etc.
