There are two main ventilation methods:
Centralized Ventilation Method
This is mainly used in large buildings, with the outside air
intake being installed in one machine room. For this method,
primary treatment of the outside air, such as energy recovery
and dust removal, is performed before distribution to the build-
ing duct system.
Independent Zoned Ventilation Method
This is mainly used in small to medium-sized buildings,
with areas being ventilated using outside air intakes from
independent ventilation devices. The rate of use of this
method has recently increased as zone conditioning and
independent control have become more feasible.

Energy Recovery Ventilators – Core
The sophisticated energy recovery technology of the LOSSNAY
®
core is constructed from a specially treated cellulose membrane
separating cross-flow air passages with a corrugated structure for strength and durability. See below, right for an illustration of the
