Our new Airostar 39SQ energy recovery units have been
designed specifically to provide efficient fresh air
solutions for buildings of all types from a standard unit.
Fresh air units with energy recovery are a major step
towards improving building efficiency and can improve energy
savings.
The new units will achieve 30 per cent energy savings
with thermal efficiencies between 54 and 86 per cent
Airostar 39SQ energy
recovery units are available in two variations:
- The 39SQR is equipped with a high efficiency
rotary air-to-air heat exchanger which offers thermal
efficiency of up to 86 per cent. It has a condensation
wheel to extract moisture recovery by condensation, and
the heat exchanger includes peripheral and transverse
seals to minimise internal leaks.
- The 39SQP is equipped with a cross flow plate heat
exchanger with a thermal efficiency of up to 54 per cent.
It has a by-pass damper which is used to control
capacity, manage the defrosting cycles and ensure free
night cooling during the summer. This technology is
recommended for those operations where possible
contamination of fresh air is not acceptable.
In addition to ‘highly significant’ efficiency savings,
this new generation AHU with energy recovery comes with a
wide range of benefits. It ranges in size from 2500 to 18000
m³/h, and all units bar one are delivered from the factory
in one piece for ease of installation. Units longer than
three metres can be separated on site for ease of access.
Airostar 39SQ units can be selected for either indoor or
outdoor installation. The supply duct connection can either
be at the top or the bottom; airflow direction can be
selected for left-hand or right-hand service access, and
optional isolating dampers—with or without actuators—are
available for extract or fresh air intakes.
In addition to energy recovery the 39SQ also has to
deliver on indoor air quality. That is why Carrier has
factored in F7 efficiency filters on all units on exhaust
and supply air streams. The 39SQR has a 500mm bag filter,
while the 39SQP has a100mm pleated air filter. The filter
racks are equipped with a manual locking device to ensure
perfect air tightness, and there is an optional service
chamber between heating and cooling units. |
