Units equipped with a heat and humidity recovery core (
enthalpic core
) can reduce
ventilation costs in winter as well as in summer.
1.
During the heating season, the unit draws the humidity and heat from the stale air and
transfers them, in part, to the cold air entering the house, thus avoiding dryness
problems and providing maximum comfort.
Example (in winter):
1.3 R

•
Units equipped with a heat recovery core (
polypropylene core
) are specifically
designed to control excess humidity and reduce ventilation costs by recovering the
heat energy from the exhausted air, and using that same heat energy to warm the fresh
air being supplied. This heat recovery process is accomplished in such a way that the
stale air is never mixed with the fresh air.
Example (in winter):
OUTSIDE
INSIDE
STALE AIR TO OUTSIDE
4°C/40°F
FRESH AIR TO BUILDING
18°C/64°F
FRESH AIR FROM OUTSIDE
0°C/32°F
STALE AIR FROM BUILDING
22°C/72°F

2.
During the cooling season, the unit reverses the process, preventing the humidity from
the outside air from entering into the house.
