VTS Ventus VVS650 [41/55] Counterflow hexagonal recuperator

VTS Ventus VVS300 [41/55] Counterflow hexagonal recuperator
Design and application
» Rotor made of aluminum with shaft
suspended on bearings, installed in
steel housing.
» Rotor lling – two layers of
alternately winded aluminium foil
– one at, the other – corrugated –
making small ducts for the air.
» Rotor drive system with smooth
revolutions control enabling to
maintain highest recovery efciency
and to adjust degree of recovery
performance.
» Purge zone reducing the
cross-contamination effect of
contaminated exhaust air to supply
to absolute minimum.
» Set of gaskets installed both on the
wheel outer edge and bar separating
supply from exhaust air being an
additional protection against cross-
contamination.
» Rotary heat wheel recovers sensible
heat from return air to supply, which
passes the unit in opposite direction.
The process enables heat recovery
in winter time, same as cool recovery
in summer.
» Humidity recovery from return
to supply in case the rotor pad
temperature is lower than dew point
of return air – typically during winter
season.
Specication
» Up to 86% of energy recovery,
depending on airow rate and its
velocity in the heat wheel window.
ROTARY HEAT WHEEL
Design and application
» Section equipped with two air inlets/
outlets aided with dampers, enabling
regulation of fresh and recirculation
air share (recirculation).
Specication
» Direct Energy recovery (sensible
and latent heat) resulting from partial
mixing of fresh air with return one.
» Control of fresh air share in entire
airow supplied to handled spaces.
» Working temperature range:
-40 ÷ +70°C."
MIXIN SECTION
Design and application
» Block of copper pipes integrated
with another block of aluminum ns,
creating expanded heat exchange
surface. Pipes are bonded to the
collectors, equipped with headers
(for connecting entire coil to the
medium supply system).
» Heating of the air supplied to the
handled spaces.
» Re-heating of the air as a part of air
dehumidifying process.
» The coil can be applied if heating
medium is available (local boiler or
district heating system).
» Coil headers are equipped with
medium damping valve and air vent.
» Connecting the coil in parallel
medium ow vs air, will result in its
capacity reduction by over a dozen
percent.
Specication
» Max glycol concentration: 50%.
» Max medium temperature: 150°C.
» Max medium working pressure:
1,6MPa = 16bar (test: 21bar).
» Heating capacity: parameter resulting
from individual performance
calculaation of selected unit (CCOL).
» Medium side pressure drop –
parameter resulting from individual
performance calculation of selected
unit (CCOL).
WATER HEATER
Design and application
» Set of resistive heating elements
made of CR-Ni-Fe alloy, 6 kW/400V
each.
» Coils mounted on hot-dip galvanized
steel frame.
» Heater is equipped with power
terminals and thermostat protecting
against overheating.
» In case of AHU with complete
controls, heater is equipped with
integrated capacity control module.
» Heating capacity can be modied by
means of smooth regulation module
(HE module, set of Solid State Relays
as optional parts of AHU controls) or
by means of automatic engaging of
next heating sections.
Specication
» Max permissible ambient
temperature around heating
elements: 65°C.
» The heater is available in a version
built in the air handling unit and in a
duct heater version (without thermal
insulation)
ELECTRIC HEATER
Design and application
» Hexagonal heat recovery
recuperator made of crosswise
stamped aluminum plates, between
which supply and exhaust air
passes alternately in counterow
arrangement.
» As standard, the recuperator is
equipped with by-pass damper,
enabling its securing against
frosting and heat recovery capacity
regulation.
» Optionally, the recuperator can be
equipped with integrated mixing box.
» The recuperator provides sensible
heat recovery for warmer air to the
colder one. For winter season –
recovery of heat from return air to
supply. For summer – recovery of
chill from return air to supply.
Specication
» Energy recovery at very high supply
and exhaust air stream separation
(reaching 99,9%).
» Heat recovery reaching up to 93%
depending on ow rate face velocity
of the air passing the recuperator.
