Ventilation is a process by which one can exchange indoor air to
outdoor air in order to improve the air quality and to maintain
environmental temperature conditions. LG's Eco V heat recovery
ventilation system modulates the temperature and humidity of
incoming fresh air to match indoor conditions. A balance is thus
achieved between indoor and outdoor ambient, enabling the cooling
or heating load placed on the air conditioning system to be
reduced significantly which can be controlled individually or
integral with the air conditioning system.
Provides efficiency, cost savings, superior performance, compact &
light design, BLDC Motor ensuring various design of duct system
and easy maintenance. Units are ideal for hotels, dormitories,
restaurants, hospitals, retail establishments, theatres, schools,
and office buildings.
High Efficiency Heat Exchanger :
Cross flow heat exchanger ensure no mixing of the stale air with
the fresh air. Efficiency and comfort is ensured by the
high-efficiency energy recovery central core which recovers energy
from the indoor air and transfers it to the fresh incoming air
without mixing airstreams. The heat exchanger also helps to remove
unwanted humidity from air inside your home during winter, and
removes the humidity from the outside air before it enters your
home in the summer.
Easy Cleaning and Filter Changing:
Door attached, side-panel and slide-removable options provide
convenient access for maintenance. What's more, enthalpy heat
exchanger filters can be changed without additional
maintenance. With regular maintenance, our air conditioners can
achieve a collection efficiency of over 80%, which means they
can filter particles up to 0.3 m, including tobacco smoke.

General
Units shall be completely factory assembled
including fan motors, filters, heat exchanger element(s) and
controls in a sheet metal casing.
Casing
Unit casing shall be constructed of zinc coated,
heavy gauge galvanized steel. All panels in the casing shall be
cleaned with permanent, fire retardant, odor-less material.
Knockouts shall be provided for unit electrical power. Panels
shall be fastened by screws.
Heat Exchanger Element
The heat exchanger element shall be assembled
without moving parts for higher durability and reliability. The
material is flame-retardant for safety. The supply air passage and
the exhaust air passage are arranged in right angle the prevent
the supply and exhaust air from getting mixed.
Fan Motor
The fan motors shall be of permanently lubricated
type with internal thermal protection as standard. The shaft shall
be protected against rusting. The fan motors shall be resilient
mounted to minimize vibration and noise. All fans shall be
statically and dynamically balanced for quiet operation.
Filters
Filters shall be easily accessible from the side
of the unit. Filters shall be fabricated from synthetic media and
shall be of washable type.
Controls
Wired control shall be available as standard. The
controls shall be microprocessor based and provide for a user
interface.
