ERV Energy Recovery Ventilation
Mitsubishi Electric offers its patented Fresh Air Energy Recovery System in Canada. The Lossnay® system utilizes fresh air to ventilate buildings, improving indoor air quality for occupants. With up to 80% sensible efficiency, Lossnay® heat-exchange technology creates highly efficient ventilation systems while minimizing energy loss. The core of Lossnay consists of a cross-flow, plate-fin configuration with a diaphragm made of specially processed paper. This paper’s advanced heat-transfer and moisture permeability properties maximize heat recovery as air circulates through the element, leading to significant energy savings and a more comfortable indoor environment.
