The Lossnay Solution - The best possible mechanical solution is to ventilate with a Lossnay Energy Recovery Ventilation (ERV) system, designed and patented during the time the oil embargo was in effect. Lossnay ERV's provide your building with the highest degree of energy recovery ventilation possible. Lossnay is the only fixed-plate design to offer both sensible (heat) and latent (humidity) exchange. Additionally, unlike wheel-type ventilators, there are no moving parts in the energy exchange process. There is nothing to wear out and less to maintain.
With Lossnay ERV systems stale indoor air is exhausted to the outside and simultaneously replaced by fresh incoming outdoor air. In the Lossnay energy exchange core the exhausted stale air and the fresh incoming air travel through multiple air passages separated by an engineered, composite-resin, partition plate. Sensible heat transfers from the warmer to the cooler air stream. Also latent energy (water vapor in the gas state) transfers from the wetter to the dryer air stream. The fresh incoming air is automatically preheated or pre-cooled, depending on the design conditions. Additionally, because the two air streams never mix, there is no need to worry about cross-contamination. Lossnay easily satisfies IAQ standards set by ASHRAE in ASHRAE 62-1989 and 90.1, while providing years of cost effective ventilation.
The unique moisture transfer feature of the Lossnay energy exchange core eliminates condensate and frosting in most applications. No mechanical or electrical defrost systems are needed, therefore offering higher heat recovery efficiencies, simpler installation, and more reliable operation. Further, drain pans and condensate handling are eliminated.
