CAUTION
PLEASE READ INSTRUCTION BEFORE COMMENCING INSTALLATION AND RETAIN FOR FUTURE REFERENCES.
The installation must conform to all applicable codes. The fresh air duct from outside and to the house and the stale air duct from the unit to
the outside must be fully insulated to prevent condensation from forming on the duct work
STRUCTURE AND OPERATING LOGIC
The unit has the following operating logic (Figure 1):
Warm stale air extracted from the indoor space is purified in the exhaust filter
and is supplied to the heat recovery core before being exhausted to an
outdoor space. Clean cold air from outside is purified through the supply filter
and is supplied to the heat recovery core before being supplied to the indoor
space.
Thermal energy of warm extracted air is transferred to the supplied fresh air
before the fresh air is supplied to a room. The extract and intake air flows are
fully separated during heat recovery which prevents any transfer of odors and
pathogens to the supply air. Heat recovery minimizes thermal energy losses,
energy demand and heating costs.
Both sensible thermal energy and latent moisture energy contained in the
extract air are transferred in the unit heat recovery core to the cold intake air
flow from outside to warm it up before supplying to the room.
ERVs: The graphene modified polymer membranes core of the unit operates
as a moisture balancer in case of low outdoor humidity or as an air dryer in
case of high outdoor air humidity. Due to high hydroscopic features of the
heat and energy recovery core material the unit does not need condensate
drainage. Application of the heat exchanger provides decreasing thermal
energy losses and heating costs saving during cold season.
HRVs: The Aluminum heat recovery core of the unit operates as a temperature
balancer in case of large temperature di erences between indoor and
outdoor. When the air streams flow through the core, condensation may
accumulate, requiring a drain for extraction out of the unit.
